Technology that interconnects computers in the world allows to be able to exchange information and data even communicate with each other in the form of images and video. The more valuable the information is required a security standard to maintain the information. Computer security target, among others, is as protection of information. The higher the security standards provided the higher the privacy protection of the information. Protection of employee privacy within a company is one factor that must be considered in the information systems implementation. Information system security policies include: System maintenance, risk handling, access rights settings and human resources, security and control of information assets, enterprise server security policy and password policy. The policies that have been reviewed, be a form of protection of corporate information

What is Security? 1.1 Introduction
The central role of computer security for the working of the economy, the defense of the country, and the protection of our individual privacy is universally acknowledged today. This is a relatively recent development; it has resulted from the rapid deployment of Internet technologies in all fields of human endeavor and throughout the world that started at the beginning of the 1990s. Mainframe computers have handled secret military information and personal computers have stored private data from the very beginning of their existence in the mid-1940s and 1980s, respectively. However, security was not a crucial issue in either case: the information could mostly be protected in the old-fashioned way, by physically locking up the computer and checking the trustworthiness of the people who worked on it through background checks and screening procedures. What has radically changed and made the physical and administrative approaches to computer security insufficient is the interconnectedness of computers and information systems. Highly sensitive economic, financial, military, and personal information is stored and processed in a global network that spans countries, governments, businesses, organizations, and individuals. Securing this cyberspace is synonymous with securing the normal functioning of our daily lives.
Secure information systems must work reliably despite random errors, disturbances, and malicious attacks. Mechanisms incorporating security measures are not just hard to design and implement but can also backfire by decreasing efficiency, sometimes to the point of making the system unusable. This is why some programmers used to look at security mechanisms as an unfortunate nuisance; they require more work, do not add new functionality, and slow down the application and thus decrease usability. The situation is similar when adding security at the hardware, network, or organizational level: increased security makes the system clumsier and less fun to use; just think of the current airport security checks and contrast them to the happy (and now so distant) pre–September 11, 2001 memories of buying your ticket right before boarding the plane. Nonetheless, systems must work, and they must be secure; thus, there is a fine balance to maintain between the level of security on one side and the efficiency and usability of the system on the other. One can argue that there are three key attributes of information systems:
Processing capacity—speed
Convenience—user friendliness
Secure—reliable operation
The process of securing these systems is finding an acceptable balance of these attributes. 1.2 The Subject of Security
Security is a word used to refer to many things, so its use has become somewhat ambiguous. Here we will try to clarify just what security focuses on. Over the years, the subject of information security has been considered from a number of perspectives, as a concept, a function, and ...

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Introduction
Information security: a “well-informed sense of
assurance that the information risks and controls are in
balance.” —Jim Anderson, Inovant (2002)
Necessary to review the origins of this field and its
impact on our understanding of information security
today
4. Principles of Information Security, 2nd Edition 4
The History of Information Security
Began immediately after the first mainframes were
developed
Created to aid code-breaking computations during World
War II
Physical controls to limit access to sensitive military
locations to authorized personnel: badges, keys, and
facial recognition
Rudimentary in defending against physical theft,
espionage, and sabotage
6. Principles of Information Security, 2nd Edition 6
The History of Information Security
One of 1st documented problems
Early 1960s
Not physical
Accidental file switch
Entire password file
printed on every output file
7. Principles of Information Security, 2nd Edition 7
The 1960s
Additional mainframes online
Advanced Research Procurement Agency (ARPA)
began to examine feasibility of redundant networked
communications
Larry Roberts developed ARPANET from its inception
ARPANET is the first Internet
9. Principles of Information Security, 2nd Edition 9
The 1970s and 80s
ARPANET grew in popularity as did its potential for misuse
Fundamental problems with ARPANET security were
identified
No safety procedures for dial-up connections to ARPANET
Non-existent user identification and authorization to system
10. Principles of Information Security, 2nd Edition 10
R-609
Information security began with Rand Report R-609 (paper
that started the study of computer security)
Scope of computer security grew from physical security to
include:
Safety of data
Limiting unauthorized access to data
Involvement of personnel from multiple levels of an
organization
First identified role of management and policy
11. Principles of Information Security, 2nd Edition 11
The History of Information Security
Multics
Operating System
Security primary goal
Didn’t go very far
Several developers created Unix
Late 1970s: microprocessor expanded computing
capabilities and security threats
From mainframe to PC
Decentralized computing
Need for sharing resources increased
Major changed computing
12. Principles of Information Security, 2nd Edition 12
The 1990s
Networks of computers became more common; so too
did the need to interconnect networks
Internet became first manifestation of a global network of
networks
In early Internet deployments, security was treated as a
low priority
Many of the problems that plague e-mail on the Internet are
the result to this early lack of security
13. Principles of Information Security, 2nd Edition 13
The Present
The Internet brings millions of computer networks into
communication with each other—many of them
unsecured
Ability to secure a computer’s data influenced by the
security of every computer to which it is connected
14. Principles of Information Security, 2nd Edition 14
What is Security?
“The quality or state of being secure—to be free from
danger”
A successful organization should have multiple layers of
security in place:
Physical security
Personal security
Operations security
Communications security
Network security
Information security
15. Principles of Information Security, 2nd Edition 15
What is Information Security?
The protection of information and its critical elements,
including systems and hardware that use, store, and
transmit that information
Necessary tools: policy, awareness, training, education,
technology
C.I.A. triangle was standard based on confidentiality,
integrity, and availability
C.I.A. triangle now expanded into list of critical
characteristics of information
17. Principles of Information Security, 2nd Edition 17
Critical Characteristics of Information
The value of information comes from the characteristics it
possesses:
Timeliness
No value if it is too late
Availability
No interference or obstruction
Required format
Accuracy
Free from mistakes
Authenticity
Quality or state of being genuine, i.e., sender of an email
Confidentiality
Disclosure or exposure to unauthorized individuals or system is prevented
18. Principles of Information Security, 2nd Edition 18
Critical Characteristics of Information
Integrity
Whole, completed, uncorrupted
Cornerstone
Size of the file, hash values, error-correcting codes,
retransmission
Utility
Having value for some purpose
Possession
Ownership
Breach of confidentiality results in the breach of possession, not
the reverse

Components of an Information System
Information System (IS) is entire set of software, hardware, data,
people, procedures, and networks necessary to use information as
a resource in the organization
Software
Perhaps most difficult to secure
Easy target
Exploitation substantial portion of attacks on information
Hardware
Physical security policies
Securing physical location important
Laptops
Flash memory
21. Principles of Information Security, 2nd Edition 21
Components of an Information System
Data
Often most valuable asset
Main target of intentional attacks
People
Weakest link
Social engineering
Must be well trained and informed
Procedures
Threat to integrity of data
Networks
Locks and keys won’t work
22. Principles of Information Security, 2nd Edition 22
Securing Components
Computer can be subject of an attack and/or the object
of an attack
When the subject of an attack, computer is used as an
active tool to conduct attack
When the object of an attack, computer is the entity being
attacked
2 types of attack
Direct
Hacker uses their computer to break into a system
Indirect
System is compromised and used to attack other systems
24. Principles of Information Security, 2nd Edition 24
Balancing Information Security and Access
Impossible to obtain perfect security—it is a process, not
an absolute
Security should be considered balance between
protection and availability
To achieve balance, level of security must allow
reasonable access, yet protect against threats
26. Principles of Information Security, 2nd Edition 26
Approaches to Information Security
Implementation: Bottom-Up Approach
Grassroots effort: systems administrators attempt to
improve security of their systems
Key advantage: technical expertise of individual
administrators
Seldom works, as it lacks a number of critical features:
Participant support
Organizational staying power
28. Principles of Information Security, 2nd Edition 28
Approaches to Information Security
Implementation: Top-Down Approach
Initiated by upper management
Issue policy, procedures and processes
Dictate goals and expected outcomes of project
Determine accountability for each required action
The most successful also involve formal development
strategy referred to as systems development life cycle
29. Principles of Information Security, 2nd Edition 29
The Systems Development Life Cycle
Systems development life cycle (SDLC) is methodology
and design for implementation of information security within
an organization
Methodology is formal approach to problem-solving based
on structured sequence of procedures
Using a methodology
ensures a rigorous process
avoids missing steps
Goal is creating a comprehensive security posture/program
Traditional SDLC consists of six general phases
31. Principles of Information Security, 2nd Edition 31
The Security Systems Development Life Cycle
The same phases used in traditional SDLC may be
adapted to support specialized implementation of an IS
project
Identification of specific threats and creating controls to
counter them
SecSDLC is a coherent program rather than a series of
random, seemingly unconnected actions
32. Principles of Information Security, 2nd Edition 32
The Security Systems Development Life Cycle
Investigation
Identifies process, outcomes, goals, and constraints of the
project
Begins with enterprise information security policy
Analysis
Existing security policies, legal issues,
Perform risk analysis
33. Principles of Information Security, 2nd Edition 33
The Security Systems Development Life Cycle
Logical Design
Creates and develops blueprints for information security
Incident response actions: Continuity planning, Incident
response, Disaster recovery
Feasibility analysis to determine whether project should
continue or be outsourced
Physical Design
Needed security technology is evaluated, alternatives
generated, and final design selected
34. Principles of Information Security, 2nd Edition 34
The Security Systems Development Life Cycle
Implementation
Security solutions are acquired, tested, implemented, and
tested again
Personnel issues evaluated; specific training and education
programs conducted
Entire tested package is presented to management for final
approval
Maintenance and Change
Most important
Constant changing threats
Constant monitoring, testing updating and implementing
change
35. Principles of Information Security, 2nd Edition 35
Security Professionals and the Organization

Critical infrastructure
From Wikipedia.
Critical infrastructure is a term used by governments to describe systems or material assets that are
essential for the functioning of a society and economy. Most commonly associated with the term are
facilities for:
electricity generation and distribution;
telecommunication;
water supply;
agriculture, food production and distribution;
heating (natural gas, fuel oil);
public health;
transportation systems (fuel supply, railway network, airports);
financial services;
security services (police, military).
Critical-infrastructure protection is the study, design and implementation of precautionary measures
aimed to reduce the risk that critical infrastructure fails as the result of war, disaster, civil unrest,
vandalism, or sabotage.
42. Principles of Information Security, 2nd Edition 42
Summary
Information security is a “well-informed sense of
assurance that the information risks and controls are in
balance.”
Computer security began immediately after first
mainframes were developed
Successful organizations have multiple layers of security
in place: physical, personal, operations, communications,
network, and information.
43. Principles of Information Security, 2nd Edition 43
Summary
Security should be considered a balance between
protection and availability
Information security must be managed similar to any
major system implemented in an organization using a
methodology like SecSDLC
Implementation of information security often described as
a combination of art and science
