1st known threat: The first know threat that a server can have is DDoS attacks. I would rate DDoS
as a 4 out of 5 because if your company is well known, it is likely that you will come across DDoS
attacks. Over all I would rate this is as a 5 because DDoS can really slow down or shut your
company down and deny access to your server. A DDoS can should be a high risk because it can
happen at any time, also it shows were your vulnerabilities are.
2nd known threat: The second know threat to a server is CSS, cross site scripting makes use of
vulnerabilities in web applications. This huge because the company uses some web applications. I
would rate CSS a 4 out of 5 because with CSS you can contract malware which will do damage to

If you don't have strong enough password form your computer such as "apple, password, MacBook"
then you can be spoofed by hackers, and they can gain unauthorized access your computer. I would
rate spoofing a 3 because you should always keep storing passwords, especially for you encrypted
files. Overall I think that spoofing is a 3 because having strong firewalls and encryption passwords
should block spoofing and hackers won't be able to attack your computer and encrypted files that
easily.
2nd known threat: Sniffing is something that can also do damage and expose your company data
and files. If your network is not secure, your company can be sniffed by hackers who are trying to
get data from you network server. I would rate sniffing a 3 because if comes as a threat when your
system files are not secure and can cause you to have you company data revealed. Over all sniffing
should be rated a 2 because having a strong firewall and security could fix the problem of sniffing,
but you should always look to see if you notice that something odd is going on in you network

Computer Security : Memory Controlr Overflow
Defining buffer overflow
Buffer overflow vulnerability considered one of the most common security exploit to exist, focuses
on buffers, or memory allocations exploits eventually giving the attacker full control over a
compromised system. This takes place when a process or programme writes or attempts to write
data onto a static sized memory block than it was initially allocated.
By taking advantage of the buffer overflow attacker are always aiming to completely take control of
the whole system by elevating their privileges to the Admin rights. To successfully attain this they
identify a function pointer in memory that they them taking advantage of the buffer overflow
functionality, where in many occasions pointing to a location where ... Show more content on
Helpwriting.net ...
Upon the crashing of the server and the exploit is identified (EIP) the attacker then has at hand
where to inject the malicious code.
7. The malicious code commonly referred to as payload/shellcode which is a sequence of machine
instruction interpretable by the computer's CPU. Will then be executed.
8. Ensured the client has netcat to listen to specified ports where our shellcode will connect back.
9. ATM this point the payload executed of choice is the reverse shell a backdoor process that runs on
the server side and as soon as its executed its connects to the client that, as soon as it is been
executed at the server side, it connects back to the client, providing an interactive command
interpreter, thus allowing us to execute commands to the server. In this instance the reverse shell
was favoured because it can easily bypass any possible Firewall filtering incoming traffic to ports
that are not being used by the server.
Remediation against buffer overflow:
Enable ARC(Automatic reference counting) – this is a compiler(programme that processes
statements writing in a programming language e.g. C,C++) attribute that enables it to automatically
manage the memory objects.[2]
Implement full ASLR (Address Space Layout Randomization) protection – this enables to choose
different locations for your stack, heap, libraries, frameworks, and executable code each time you
run your software
Implement stack–smashing protection – Commonly done when compiling and

Lab Investigation : Email And Internet Artifacts Essay
Week 4 Lab Investigation: Email and Internet Artifacts This week's lab is a continuation of the
Blacksuit Case Investigation using the EnCase software. The goal is to use knowledge gained from
EnCase Tutorials and explore the emails sent and received by Jane, as well as identify her Internet
browsing activities in an effort to identify any potential issues. The specific questions about the
email that must be answered are: Who has Jane been communicating with via email? Are email
senders, or recipients, suspicious? What would be the next system checked based on the email's
contents? In terms of the Internet artifacts, the questions that must be addressed are: Did Jane visit
any suspicious websites? Why would the student deem them as suspicious? Did Jane download any
software? What was the software potentially downloaded? What is the software's legitimacy?
Finally, the student will attempt to infer and form a hypothesis from the information collected at this
point in the investigation, including information from Internet Explorer Internet history, and web
cache. To begin to answer these questions, the email collected in the case must be examined to see
who Jane communicated with. Under the Email Tab under the Records Tab in EnCase shows Jane's
email folder structure with two messages and her Inbox (Appendix A, figure 1). The two messages,
'msg_43.txt' and 'msg_25.txt' are suspicious messages originating from Jane's account. The first,

1. What does the shell ordinarily do while a command is executing? What should you do if you do
not want for a command to finish before running another command?
While the command is executing, the shell waits for the process to finish. Or sleeps
3. What is a PID number? Why are these numbers useful when you run processes in the
background? Which utility displays the PID numbers of the commands you are running?
PID process identification numbers. Each of these numbers identifies the command running in the

$ cd $HOME/biblios
After executing the preceding commands, Zach's working directory is
/home/zach/biblios. When you give cd an absolute pathname as an argument, cd does not use
CDPATH.
8. Enter the following command:
$ sleep 30 | cat /etc/services
Is there any output from sleep? Where does cat get its input from? What has to happen before the
shell displays a prompt?
There is no output from sleep (try giving the command sleep 30 by itself).
The /etc/services file provides input for cat (when cat has an argument, it does not check standard
input). The sleep command has to run to completion before the shell displays a prompt.
Chapter 9, p.357, Advanced Exercises 10,11
10. Write a shell script that outputs the name of the shell executing it.

There are many ways to solve this problem. The following solutions are all basically the same.
These scripts take advantage of the PPID shell variable, which holds the PID number of the shell
that is the parent of the process using the variable. They also use the fact that echo changes multiple
sequential SPACEs to a single SPACE. The cut utility interprets multiple sequential SPACEs as
multiple delimiters, so the script does not work properly without echo.

Operating System Structure Of A Single Large Executable...
OPERATING SYSTEM STRUCTURE The operating system can be defined as a collection of
written procedures, linked together into a single large executable binary program. The most useful
and better approach is divide the task into small components /modules instead of having one
monolithic system so that the operating system can function properly and can be modified easily.
Input, output and functions should be clearly defined in each of the system modules as far as we can
finally come with large and complex system. Simple structure, layered structure, microkernel,
client–server systems and virtual machines are among different structures of operating system.
1.Simple Structure Well defined structures are very important in operating systems. Scope,
functionality and well designed modules are main factor to consider to make sure the system will
satisfy user needs and provides a good service to users.MS–DOS is a good example of Simple
structure because of its history which starts with small, simple and limited system that did not
consider about the number of users and possibility of become popular operating system that can be
able to accommodate as many users as possible.MS–DOS do not consider the matter of separation
between the interfaces and levels of functionality. As Silberschatz (2013) observation on weakness

Designing A Windows Registry Autorun
MSC.BAT was used to initialize the persistent installation of the other two binaries,
NTLHAFD.GCP and NTSVCHOST.EXE, and cleanup the installation. A Windows registry Autorun
key was set to provide persistence. NTLHAFD.GCP was the backdoor and was encrypted with RC4
stream cipher and compressed using the Zlib library (GReAT, 2013a). Before executing the
decryption and memory load routines, the loader, NTSVCHOST.EXE, first attempted to connect to
legitimate Microsoft domains (update.microsoft.com, www.microsoft.com, and
support.microsoft.com) to determine if the victim computer was able to route to the internet. If the
infected computer was not online, the loader would not decrypt the backdoor, NTLHAFD.GCP.
When online, the loader would execute the decryption and memory load routines, and the backdoor
would communicate periodically with the designated Command–and–Control server. From an
antivirus perspective, the backdoor that was on disk was encrypted, and the more nefarious code
was only in its unencrypted form while in memory. In order to reverse engineer the malware, it
required either connecting to the internet or tricking the malware into believing it was on the
internet.

establishing a connection to one of the three hardcoded Command–and–Control servers built into
every installation of Red October, the backdoor was capable of loading additional modules. Some of

Ip Delivery For Fpgas Using Applets And Jhdl
Paper Summary The paper, "IP Delivery for FPGAs Using Applets and JHDL", describes the use of
Java applets in order to provide IP (Intellectual Property) based FPGA delivery and evaluation. As
IP–based FPGA approach has significant advantages such as it improves the productivity/quality,
and reduce design time. FPGA IP uses Java applets that allow designers to create, evaluate, test and
obtain circuits, and that too has to be done within a web browser. Several other approaches have
been introduced, which are similar to JHDL. Those can be described as follows;  Web–CAD: It
uses client–server architecture and transfers the simulation events across the network  Java CAD:
This is similar to Web–CAD. It has applets which are described in Java and uses RMI (Remote
Method Invocation) over the internet for simulating and evaluating the circuits.  JBits: This tool
does not use the internet to deliver IP cores and delivers pre–placed IP core. It is easily incorporated
with online Java applets. In Java–based applets, here "JHDL" is used as a design environment. It is
developed at BYU used for creating high–performance FPGA. JHDL libraries provide the
components and wires that are used to create the instance. The programming language used here is
Java and for simulation and compilation, Java Virtual Machine (JVM) platform is needed. Variety of
design tools it supported, such as  Schematic Viewer, allows the designer to quickly view the
structure and hierarchy of a circuit. 

Clinical Decision Support System ( Cdss ) Essay
Background Information Clinical decision support system (CDSS) is gaining increased recognition
in healthcare organizations. This is due to an increasing recognition that a stronger CDSS is crucial
to achieve a high quality of patients care and safety1,2. CDSS is a class of computerized
information system that supports decision–making activities2. It uses patient data to provide tailored
patient assessments and evidence–based treatment recommendations for healthcare providers to
consider2,3". Patient data can be input by digital entry, queried from other clinical information
systems or transmitted from medical devices. Patient data are compared against a knowledge–base
and made sense of by an inference mechanism. The knowledge base can be procured commercially
or developed in–house. The inference mechanism can be highly variable in sophistication ranging
from a simple 'yes 'no and 'if 'then statement to Bayesian prediction techniques and/or fuzzy logic.
The output can also take a number of forms and can be delivered to a number of destinations at any
time before, during or post–interaction with the patient4. CDS is most effective when provided at
the time that the physician is formulating her assessment of the patient's condition and is making
ordering decisions2. CDS encompasses a variety of tools to enhance decision–making in the clinical
workflow. These tools include computerized alerts and reminders to care providers and patients;
clinical guidelines;

Annotated Bibliography On The Development And Adoption Of Cds
Even where CDS is deployed, the implementations often do not effectively use and present the best
available clinical knowledge, thereby limiting the impact and degree of clinical improvement. More
specifically: – drug–drug interaction checking modules and drug–allergy checking modules are the
primary CDS interventions that are routinely being purchased and implemented. – Many
organizations that use CDS do not have dose checking capabilities. – Some current CDS systems
generate too many "false positive" alerts, or interrupt clinical workflows in a manner that can
disrupt efficient care delivery. Despite their potential to significantly improve health care, advanced
clinical decision support (CDS) capabilities are not widely available in the clinical setting. An
important reason for this limited availability of CDS capabilities is the application–specific and
institution–specific nature of most current CDS implementations. There is a critical need to enable
CDS capabilities on a much larger scale is the development and adoption of standards that enable
current and emerging CDS resources to be more effectively leveraged across multiple applications
and care settings. Standards required for such effective scaling of CDS include (i) standard
terminologies and information models to represent and communicate about health care data; (ii)
standard approaches to representing clinical knowledge in both human–readable and machine–
executable formats; and (iii) standard approaches for

Essay On My Second Attack
My second attack is an offline dictionary attack against team 10718 (Will Xu). Will stores the salted
SHA1 hash of each user's pin in their card file. He salts the hashes by concatenating the pin with the
user's name and their account creation time in seconds since Jan 1, 1970. However, usernames can
easily be found by examining the card's file name and the creation time can be found by examining
the file's creation date. As a result, this salting doesn't do much to protect against an offline
dictionary attack against a single user. My attack examines .card files and prints out their associated
pins. It does this by conducting a brute–force attack in which it guesses creation times and pins and
checks the value of Hash(username || pin guess || time guess) against the value of the hash which is
stored in the .card file. Because I'm able to make good guesses about the card creation time and the
pin is short enough to turn up in a small dictionary of possible pins, this attack typically runs in
under a second. While it would be possible to examine the card file's creation time to accurately
estimate the timestamp which was used in the salt, my attack code simply guesses ... Show more

Please note that this will throw an error unless you manually create the bin folder. Additionally, you
should also be aware that Will's ATM code has a bug which can cause it to hang (he acknowledges
this bug in his design doc). To test my attack, you must compile pin_extractor.c using the command
"gcc –lcrypto pin_extractor.c". You must then run the bank executable and create a user with a
command such as "create–user bob 2134 1". Then run the executable which was created by building
pin_extractor.c and pass in a path to the card file which the bank just created. This can be done using
a command such as "./a.out bob.card". This should print the user's pin to the terminal. The following

Problems With Battling Malware Have Been Discussed, Moving...
Now that issues with battling malware have been discussed, moving to solutions is the next step.
Utilizing deobfuscation, especially through signature analysis, has already been discussed to its
fullest potential. New methods include CPU analyzers, holograpy, eigenvirus detection, differential
fault analysis, the growing grapes method, and whitelist protection. These are more general
approaches and therefore do not rely on storing certain specific characteristics of the code of
malware and tend to analyze behavior. Due to the extreme focus on deobfuscation, these ideas have
only been explored fairly recently and are currently underdeveloped. As was stated in the previous
section, CPU analyzers are a possible valid method of detecting malware. While it can be unreliable
alone, O 'Kane et al. believe it can be a good preliminary detection method for metamorphic
malware due to high CPU processing times (2011). The main issue is valid processes may trigger a
warning with this type of detection. This is why it must be paired with another detection method. A
newer study examines a type of anti–malware called holography. Dai, Fyodor, Wu Huang, and Kuo,
researchers at the National Taiwan University and the Research Center for Information Technology
Innovation in Taipei, state that holography utilizes CPU analysis and memory instructions in order
to analyze malware and detect infections (2012). However, this method is, in general, more useful
currently as an analysis method

Malware Analysis And Detection Techniques
MALWARE ANALYSIS/DETECTION TECHNIQUES
Sikorski & Honig (2012), explain the fact that when carrying out malware analysis and detection,
only the malware executable is present, which is usually not in natural language form. A variety of
tools and techniques need to be employed to ensure that the underlying information is revealed. Two
basic approaches to malware analysis and detection include: static analysis (observing the malware
without running it), and dynamic analysis (running the malware). They can be done either in the
basic form or more advanced ways.
Static Analysis
In the basic form, static analysis involves carefully observing the executable file without looking at
the actual commands or instructions. This is done to ascertain that a file is indeed malicious, give
information about its functions, and occasionally give information that will enable one produce
simple network signatures. This process is straightforward and can be performed quickly, but in
most cases, it is not effective when dealing with sophisticated malware, and may miss significant
behaviours. An example of static analysis is the use of antivirus software such as AVG for malware
analysis. Unique identifiers called hashes can also be used to identify malware in static analysis.
Dynamic Analysis
In the basic form, dynamic analysis techniques involve both running the malware code and
examining its behaviour on the system or network so as to remove the infection, derive effective
signatures, or

overflowing the buffer on a stack frame and overwriting the return address of the function, thereby
jumping to another portion of the stack frame that contains malicious executable code that had been
placed there as a result of the buffer overflow. – By preventing the execution of code from the stack
segment, this problem is eliminated. – Approaches that use a better programming methodology are
typically built around the use of bounds–checking to guard against buffer overflows. – Buffer
overflows do not occur in languages like Java where every array access is guaranteed to be within
bounds through a software check. Such approaches require no hardware support but result in run–
time costs associated with performing

Rational Unified Process
Introduction This paper has the intention to explain what Rational Unified Process (RUP) is like an
IBM product and a CASE tool. After is explained what phases it has, what are the most common
extensions thus what are its workflows more used. The Rational Unified Process (RUP) is a
software design method created by the Rational Software Corporation and now is part of IBM
developer software. This paper describes how to deploy software effectively. The Rational Unified
Process (RUP) use commercially proven techniques, and is a heavy weight process, and hence
particularly applicable to larger software development teams working on large projects. Rational

The nature of the iterations will not necessarily change much; but the longevity of the software
produced will certainly increase. Early iterations (usually in the inception phase) have a tendency to
be thrown out. During elaboration, you will discover the rest of the use cases (or at least their first
approximations) and will implement the minimal set. During construction, users will drive towards
giving the customer the minimum system that they need. The nature of the iterations will not change
much, but your focus will be on identifying the smallest possible deliverable that will still meet at
least some of the customers needs. During construction, the use cases will change a bit as the
customer sees the growing system and feeds changes back to you. During transition, users will drive
towards fleshing out the functionality of the system, and incorporating the mounds of customer
feedback that users are surely to get. The nature of your iterations will not change much. During
transition, the use cases are likely to undergo drastic changes as the customers actually use the
system and realize that it is not exactly what they needed. Again, the essence of RUP is iteration,
and the essence of iteration is the production of executable deliverables. Users may also be
producing UML diagrams, or some other form of model too. Such models take two forms. One is a
model of the architecture, which is seeded during inception and established during

Source Code Essay
There are several definition of source code, which makes regulating it difficult because different
regulators may have varying conceptions of just what it is, and as a result, what kinds of rules
should attach to it.
The general definition of source code that most people acknowledge is "the version of software as it
is originally written by a human in plain text" (Source Code). According to this definition, code is
written by humans in order to create software, which can be any operating system, program or data
with a processor. The average person can see that the source code would be the code that the
software needs in order to function. This is source code but source code is also much more.
Another definition states holds that source code is "any fully executable description of a software
system. It is therefore so construed as to include machine code, very high level languages and
executable graphical representations of systems" (Harman). At first glance, it seems just like the
other definition. However, it only seems that way because we automatically apply the assumption
that the "executable description" is the same as the "version of software" which may not necessarily
be the case. The description leads us to believe that the source code does not necessarily have to run
the software but can just be a description for said software. The first definition leads us to believe
that the code is that specific software. The second definition also mentions "machine code" and

Analysis And Design Of Software
Structured Programming, Nassi–Shneiderman Structure Charts, Formal Proofs of Correctness, and
Structured Analysis and Design are all tools to help with analysis and design of software. Each topic
is described briefly below with respect to software development and project management. At its
core, Structured Programming is a method to organize code. The intent of the rules laid out by the
method is to make code easier to read, understand, and maintain (3). Most software projects are
large and written by many programmers. Employing Structured Programming provides strict
guidelines on coding practices. These guidelines are designed to decrease development time,
improve readability, and increase maintainability. There are three components of structured
programming: Control Structures, Subroutines, and Blocks (13). Control Structures are further
broken down into Sequences, Selections, and Iterations. Sequences are lines of code that are
executed in a specific order. Selections are only executed when the program is in a certain state, and
Iterations are loops that are executed until a certain condition is met. Both Subroutines and Blocks
are units of code that are executed together. Blocks have specific syntax in order to group the lines
of code together and are only present in some languages. They are a way to group executable code
in order to make sense to the reader and clearly define sections and functionality of the code. The
grouping is motivated by the flow of information

Designing A Client Server Application
Abstract–Distributed multiprocessor operating systems is a course that involves exploring new
concepts in the field of operating systems and its internals. This course clearly elaborates the
concepts of operating systems, distributed systems and internals and how are they utilized. It clearly
explains how multiprocessors in operating systems are used in today's world. The course also
involves a four phase project to create a client server application that demonstrates the usage and
application of various concepts like reentrancy, synchronization, etc. operating systems. The project
clearly introduces us to the concepts of distributed memories, remote procedure calls, shared

and how can they be applied. As we all know, semaphores can be defined as the variables whose
access are completely dependent on the wait and signal operations that are performed and are also
termed as P and V [1]. It clearly explained the concepts of producer–consumer problems, reader–
writers problems and also helped realizing the potential situations where the problem could actually
arise and also taught the ways in which we could solve these problems. Reentrancy is another key
concept that plays a key role in multiprocessor operating systems. It is under normal cases that
multiple interrupts do occur in a system sometimes. At this point of time, we face certain situations
where some of the functions need to be called back after the interrupt is handled, on the other hand
similarly few of the other functions can be left unhandled [2]. This however depends on the
particular situation that we need during the execution. Hence, calling a function back after the
sudden interruption of its execution is called reentrancy [2]. Similarly, if the function is said to have
an undefined behavior when it is called after an interrupt occurred, then it is said to be non–reentrant
function [2]. This project helped us to implement functions which can be reentrant.
The project has been implemented in four different phases, where each phase acts as an input to the
others.

A New Family Of Apple Os X And Ios Malware
WIRELURKER
Yedavalli Anantha Nag 30131626
ABSTRACT:
A new family of apple os x and ios malware was detected by palo alto networks , named wireluker .
It heralds a new era in malware across Apple's desktop and mobile platforms . It is the second
detected malware family that attacks iOS devices through OS X via USB and can infect installed
iOS applications similar to a traditional virus. This malware install's third–party applications on
non–jailbroken iOS devices through enterprise provisioning. WireLurker was generally used to
trojanize 467 OS X applications on the Maiyadi App Store, which was a third–party Mac application
in China. In the past six months, 469 infected applications were downloaded over 356,106 times and
have impacted thousands of devices.
WireLurker attacks any iOS device connected to USB with an infected OS X computer and installs
maiyadi applications or automatically generated malicious applications onto the device. WireLurker
exhibits anti–reversing with the help of multiple component versions, customized encryption, code
obfuscation, hiding files and complex code structure.

Advantages Of Heuristic Detection Techniques
3.2. Heuristic detection technique
This technique is also known as proactive technique. This technique is similar to signature based
technique, with a difference that instead of searching for a particular signature in the code, the
malware detector now searches for the commands or instructions that are not present in the
application program. The result is that, here it becomes easy to detect new variants of malware that
had not yet been discovered. Different heuristic analysis techniques are:
3.2.1. File based heuristic analysis
It is also known as file analysis. In this technique, the file is analyzed deeply like the contents,
purpose, destination, working of file. If the file contains commands to delete or harm other file, than
it is ... Show more content on Helpwriting.net ...
It combines the code structure of program under inspection. If static analysis can calculate the
malicious behavior in the application then this information can then be used for future security
mechanism.
One of the advantages of static analysis is that the cost of computation is low. It requires less time
and low resource consumption as well.
6. Disadvantage of Static Analysis
Static analysis does not take stand for analyzing the unknown malware. The source code of many
applications is not easily available. Code obfuscation makes the pattern matching a major drawback
in detecting the malicious behavior. For doing static analysis, researchers must be expert in
assembly language and should have a deep understanding about the functioning of operating system.
7. Conclusion
Static analysis is a technique to detect malicious behavior by analyzing the code segments. This
technique is carried out without running the application in an Android emulator or device. However,
this technique has a major drawback of code obfuscation and dynamic code loading. This paper
discusses about what is Android Static Malware analysis, different methods and techniques, types of
static analysis and its components. This paper also states the advantages, disadvantages and
limitations of static malware

A Brief Note On The Primary Function Of Exec
Lab 2
CSNB324
Muath Abdullah SN091649
Answer Q1:
Execv(): it is a prototype of exec family, v is added to indicate the type of argument which in this
case specified as a vector (array of character pointers). The primary function of exec () system call
is to execute a file or a program. This is done by creating a new process image from a regular,
executable file.
This file is either an interpreter script or an executable file object. It has the form execv(char *path,
char *argv[], char *envp[]). The path argument is the pathname of a file that contains the new
program to be executed. The argv array is a list of parameter strings, and the envp array is a list of
environment variable strings and values that should be used when the process begins executing the
new programs. When a process encounters the execve() system call, the next instruction it executes
will be the one at the entry point of the new executable file.
Execvp()
The created child process does not have to run the same program as the parent process does. The
exec type system calls allow a process to run any program files, which include a binary executable
or a shell script. On this page, we only discuss one such system call: execvp(). The execvp() system
call requires two arguments: 1. The first argument is a character string that contains the name of a
file to be executed.
2. The second argument is a pointer to an array of character strings. More precisely, its type is char
**, which is exactly identical to the

Related Professions Rutgers, the State University of New Jersey BINF 5005 Assignment 2 Fall 2015
Background Information Clinical decision support system (CDSS) is gaining increased recognition
in healthcare organization. This is due to an increasing recognition that a stronger CDSS is crucial to
achieve a high quality of patients care and safety1,2. CDSS is a class of computerized information
system that supports decision–making activities2. It uses patient data to provide tailored patient ...
The output can also take a number of forms and can be delivered to a number of destinations at any
time before, during or post–interaction with the patient4. CDS is most effective when provided at
the time that the physician is formulating her assessment of the patient's condition and is making
ordering decisions2. CDS encompasses a variety of tools to enhance decision–making in the clinical
workflow. These tools include computerized alerts and reminders to care providers and patients;
clinical guidelines; condition–specific order sets; focused patient data reports and summaries;
documentation templates; diagnostic support, and contextually relevant reference information,
among other tools. Computer–assisted decision support is only acceptable when it allows the
physician to override a system–provided recommendation and choose an alternative action2. The
most successful decision–support intervention makes complying with the suggested action easy. A
brief rationale is generally provided with the recommendation, and complying with the
recommendation is as easy as hitting the Enter key or clicking the mouse. CDSS can vary greatly in
design and function, undergoing a constant evolution of their scope and application4. The majority
of CDS applications operate as components of comprehensive electronic health record systems,
although

Operating System Structure Of A Single Large Executable...
OPERATING SYSTEM STRUCTURE The operating system can be defined as a collection of
written procedures, linked together into a single large executable binary program. The most useful
and better approach is divide the task into small components /modules instead of having one
monolithic system so that the operating system can function properly and can be modified easily.
Input, output and functions should be clearly defined in each of the system modules as far as we can
finally come with large and complex system. Simple structure, layered structure, microkernel,
client–server systems and virtual machines are among different structures of operating system. 1
Simple Structure Well defined structures are very important in operating systems. Scope,
functionality and well designed modules are main factor to consider to make sure the system will
satisfy user needs and provides a good service to users.MS–DOS is a good example of Simple
structure because of its history which starts with small, simple and limited system that did not
consider about the number of users and possibility of become popular operating system that can be
able to accommodate as many users as possible.MS–DOS do not consider the matter of separation
between the interfaces and levels of functionality. As Silberschatz (2013)," stated that an application
programs are able to access the basic I/O routines to write directly to the display and disk drives.
Such freedom leaves MS–DOS vulnerable to errant (or malicious)

Orientation, the Enemy statement was simply a repeat of what was given by the evaluator, and there
was no "in order to" for the Mission. The SOM briefed was too vague with no executable
instructions provided, and SNC failed to provide any Tasks. During the execution, SNC placed
himself in an appropriate location where his FT could hear him and he would be able to assist as
necessary; however, he was timid with little confidence or command presence. Instead of ordering
his FT members to complete tasks he asked them if they were comfortable doing those things.
Because of this, SNC did employ his FT members well and when they were able to successfully

He does pass information based upon memory instead of having a solid understanding of why he is
saying it. The Orientation was missing a purpose and the Mission had no "in order to" statement.
The SOM was very thorough indicating that SNC had developed a plan of action. Once the
execution began, SNC placed himself where he could best be seen and heard by his FT. SNC does
not yet possess a solid understanding of how best to employ his subordinates. When one of his FT
members made it to the far side of the obstacle, SNC realized there was no logical reason for having
sent him over there so he told him to touch the red and take the penalty. He only did this to get his
FT member off the obstacle quicker instead of maneuvering back to the beginning. SNC acted too
hastily when he realized time was short. He attempted to maneuver the obstacle on his own, with no
purpose behind his actions, and paying no attention to where the red areas on the cables were. His
FT lost confidence in him as they were just standing off to the side watching him not attempting to

Development Of A Simulation Management System
Summary
The main contribution of the proposed research is the development of a Simulation Management
System. Simulation models are vital to modern scientific research. These models tend to be
extremely complex, often with many sources of uncertainties and numerous factors. To understand
the impact of these factors and their interactions, on the simulation model results, requires effective
design of experiments. DoE allows construction of well defined procedures for ordering experiment
outcomes and offers a framework that can be used to replicate and validate those outcomes. In this
study, we propose an approach that integrates concepts of model–driven engineering, intelligent
agent technology, and variability modeling to support the management of the lifecycle of a
simulation experiment. The Model–Driven Engineering (MDE) methodology provides a framework
and strategy to move from the platform–independent experiment domain space to the technical
space involving platform–specific executable simulation experiment scripts. Experiment design
modeling is introduced for configurable experiment synthesis and execution. Feature–oriented
variability modeling is used to design a family of experiments by allowing explicit specification of
variability in the configuration of experiments Adaptation is needed for continuous management of
stochastic simulation experiments. In simulation lifecycle management systems, adaptation is
proposed for dynamic experiment model updating.

Computer Crime Report – CM0431
Introduction
In this computer crime report, the following will be discussed about the computer crime of Botnets.
This report will explain the role of computer forensics has in detecting and deterring the use of
botnets, the hardware and software used in forensically investigating botnets, the legal context of
using botnets such as legislation related to offences caused by using botnets, and the ethical and
professional challenges faced by computer forensics practitioners in investigating botnets.
A botnet is defined ( http://www.pcmag.com/encyclopedia/term/38866/botnet, 2014) as a
compromised group of computers, generally in large groups, that are used to generate spam (such as
phishing emails in large quantities), spread viruses to infect new machines, and flood a network or
web server using an enormous amount of request repeatedly and cause it to fail, this is known as a
distributed denial of service attack (DDOS).
The infected computers are normally infected by a Trojan horse virus, once infected the virus
usually opens an Internet Relay Chat (IRC) channel, this channel will wait for commands from the
user in command of the botnet network. In the modern world, there is large, and growing, industry
of selling lists of infected computers to hackers and spammers.
Rik Ferguson (2010) stated the first use of botnets came about in 1999, and the malware that started
it all off was known as "Sub7", a Trojan virus and "Pretty Park", a computer worm.

Abstract– In this paper two set of edge–texture features is proposed such as Discriminative Robust
Local Binary Pattern (DRLBP) and Discriminative Robust Local Ternary Pattern (DRLTP) for
object recognition. The proposed DLBP and DRLTP are derived from the drawback of the Local
Binary Pattern (LBP), Local Ternary Pattern (LTP) and Robust LBP (RLBP).The LBP code and the
RLBP code are mapped in the same block .The proposed feature solves the problem of
discrimination between a bright object against dark background and vice–versa. The proposed
feature retains contrast information for representation of object contours the LBP, LTP and RLBP
discards. By this proposed features the objects in the image can be further analyzed for the exact
location of the object in the given image.
Keywords– Object recognition, Local Binary pattern, Local Ternary Pattern, Texture, features
