Given below is an issue that you have identified as an issue in a retail company: Assume the
organization is a typical retailer with a corporate network installation. Store networks are
connected to the backend servers via the POS machines. Network administrators use Telnet to
access the network and network passwords never expire. Administrators should only access the
network internally. Complete a risk qualification for this organization and identify the following:
Vulnerability: Threats (threat actor and activity): Severity: Likelihood: Sensitivity:
Solution
According to the above corporate network infrastructure, the following risks can be found in
terms of security & Risk Management:
Vulnerability: As authentication credentials and all the commands are sent to the network device
in cleartext format, it could allow for eavesdropping or manipulation of data in transit between
the user and the network device.
Threat: It\'s a kind of internal abuse.A savvy insider could interpret and steal sensitive
information or credentials of an authorized administrator as it traverses the network.
Severity: Payment card information traverses these n/w devices between the point of sale system
(in the stores) and back-end servers (corporate data centers). If they can get access to the n/w
device, they can have the full control or access to view any of this sensitive data.
Likelihood: Although it is possible to view any data in a Telnet session, it is not trivial to sniff
traffic on a switched network. The attacker would need to be in the path of the communication
between the network device and the administrator, or the attacker would need to exploit a
vulnerability on another network device in the path. Additionally, the attacker would need some
knowledge of the network device technology in order to capture and view data traversing the
network device after gaining access. The probability of the attacker gaining access once the
credentials have been stolen is further reduced by the use of Access Control Lists (ACLs) on the
network device to limit Telnet connections to certain source IP addresses used by network
administrator’s workstations. Given that the password never expires and is therefore likely not
ever to be changed, the chance of interception and successful exploitation increases over time.
The attack vector with the most the highest probability of success would be from the store
network.
Sensitivity: A breach of this sort would require the organization to publicly report the incident,
costing the company over $500,000 directly in the form of fines and lawsuits and also indirectly
when approximately 10% of clients switch their business to a competitor..

The Cyber Kill Chain. 7 Stages of Cyber Kill Chain Supplementary ReadingMuhammad FAHAD
The “cyber kill chain” is a sequence of stages required for an
attacker to successfully infiltrate a network and exfiltrate data
from it. Each stage demonstrates a specific goal along the attacker’s
path. Designing your monitoring and response plan around the cyber kill chain model is an effective method because it focuses on
how actual attacks happen.

Computer Security
Computer Security Goals
Computer security must be viewed in a holistic manner and provide an end-to-end protection
as data moves through its lifecycle. Data originates from a user or sensor, passes over a
network to reach a computing system that hosts software. This computer system has software
and processes the data and stores in in a storage device. That data is backed up on a device
and finally archived. The elements that handle the data need to be secure. Computer security
pertains to all the means to protect the confidentiality, integrity, availability, authenticity,
utility, and possession of data throughout its lifecycle.
Confidentiality: A security principle that
works to ensure that data is not disclosed to
unauthorized persons.
Integrity: A security principle that makes sure
that information and systems are not
modified maliciously or accidentally.
Availability: A security principle that assures
reliable and timely access to data and
resources by authorized individuals.
Authenticity: A security principle that the
data, transactions, communications or
documents are genuine, valid, and not
fraudulent.
Utility: A security principle that addresses
that the information is usable for its intended
purpose. .
Possession: A security principle that works to
ensure that data remains under the control of
the authorized individuals.
Figure 1. Parkerian Hexad (PH) security model.
The Parerian Hexad (PH) model expands on the Confidentiality, Integrity, and Availability (CIA)
triad that has been the basic model of Information Security for over 20 years. This framework is
used to list all aspects of security at a basic level. It provides a complete security framework to
provide the means for information owners to protect their information from any adversaries
and vulnerabilities. It adds Authenticity, Utility, and Possession to CIA triad security model. It
addresses security aspects for data throughout its lifecycle.
The Center for Internet Security has identified 20 controls necessary to protect an organization
from known cyber-attack. The first 5 controls will provide effective defense against the most
common cyber-attacks, approximately 85% of attacks. The 5 controls are:
1. Inventory of Authorized and Devices
2. Inventory of Authorized and Unauthorized Software
3. Secure Configurations for Hardware and Software
4. Continuous Vulnerability Assessment and Remediation
5. Controlled User of Administrative Privileges

javaFix in the program belowhandle incomplete data for text fil.pdfbirajdar2
java
Fix in the program below:
handle incomplete data for text file and allow to search multiple items at once
and let it sort duplicate values
and most importantly let it use get and set methods on the Nodes
New Internal Requirements :
For this assignment, you should replace your Database class with another implementation which
uses instances of the Java Collections java.util.LinkedList class to replace your hand-crafted
LinkedList classes. Note the following:
• LinkedList is a generic type; you must instantiate it with concrete class types. Thus, your
Database object will contain several LinkedList objects; you will need to organize these lists into
another instance of LinkedList. (Consider creating a Year object to help with this.)
• You are still required to maintain your lists in sorted order. The pre-built LinkedList methods
do not directly support relative insertion into a linked list; you will need to find ways to
accomplish this with the tools available to you. (There are at least a couple of ways to do this.)
New function to add:
• A new command should be implemented which allows the user to edit a storm from the main
menu. If selected, the program should prompt the user for the year and storm name to be edited.
If a matching storm is found, the corresponding record should be displayed and the user
prompted for new information to be placed in the record. Users may not change the year or storm
name, but may change any of the other information. If no matching storm is found, no action
should be taken. The user should be informed of the outcome in any case.
this is what the txt file the program is reading from looks like:
2000/Alex/0110/0120/0
2001/Bill/0210/0220/0

How do hydrophobic and hydrophilic hormones differ in their speeds a.pdfbirajdar2
How do hydrophobic and hydrophilic hormones differ in their speeds and modes of action?
Solution
Hydrophobic hormones are fat soluble while hydrophilic hormones are water soluble.
Hydrophobic hormones speed and modes of action is slower than the hydrophilic hormones as
they have to cross the cell membrane ,bind to receptors, go to nucleus and then attach to
particular DNA sequence for gene expression to occur while hydrophilic hormones simply attach
to receptors on cell surface and trigger a chemical recation. Mode of action: Hydrophobic
hormones pass through the cell membrane and bind to receptors present inside the cell forming a
hormone receptor complex.This complex then moves to nucleus of the cell and bind to a
particular DNA sequence.This either turns on or turns off the expression of the gene resulting in
production of enzymes that regulate the activity of the cell whereas in case of hydrophilic
hormones the speed and action is faster as they bind directly to receptors (particularly G proteins
)that are expressed on the cell surface and initiate a signaling event involving second messenger,
such as cyclic adenosine monophosphate (cAMP). The second messengers then function to
amplify the hormone signal to a greater extent thereby resulting in efficinet and faster response.
Overall the speed and mode of action of hydrophilic hormones is faster than hydrophilic
hormones..

Explain Aquinas\' 5 proofs of God, being sure to identify the \"Aristotelian\" elements in each
proof.
Solution
Part I. The Argument from Motion. (Thomas argues that since everything that moves is moved
by another, there must thereby exist an Unmoved Mover.)
Part II. The Argument from Efficient Cause. (The sequence of causes which make up this
universe must have a First Cause.)
Part III. The Argument to Necessary Being. (Since all existent things depend upon other things
for their existence, there must exist at least one thing that is not dependent and so is a Necessary
Being.)
Part IV. The Argument from Gradation. (Since all existent things can be compared to such
qualities as degrees of goodness, there must exist something that is an Absolutely Good Being.)
Part V. The Argument from Design. (Also named “The Teleological Argument”— The intricate
design and order of existent things and natural processes imply that a Great Designer exists.).

Exercise 7. Show that if C/(0) (the punctured plane) and U C are conformally equivalent, then
C/U has no interior, i.e. the complement of U contains no open sets.
Solution
Let P be the punctured plane and U be conformally equivalent.
Then the complements P\' (of P) and U\'( of U) will be topologically equivalent.
But P\' ={0} is a singleton...has no interior points..(hence contains no open sets)
So the same it true of U\'.
Hence the result.

Solution
a) Physical address for 4,44:
2200+44 = 2244
Physical address for 1,22:
Illegal reference
b) Paging and segmentation are different in the following ways:
1) A page is a contiguous range of memory addresses which is mapped to physical memory
whereas a segment is an independent address space.
2) A has only one linear address space whereas a segment has many address spaces.
3) A page is a physical unit whereas a segment is a logical unit..
Can you explain the movement of ions and ion channel activity during.pdfbirajdar2
Can you explain the movement of ions and ion channel activity during the resting and action
potential?
Solution
Action potential is the potential due to the which the impulse is passed from one neuron to
another.
Resting stage - in resting stage the inside has higher concentration of Potassium ions ie (-ve)
sign,wheareas the outside it has high concentration of Sodium ions ie (+ve) ions..!! The
membrane is slightly permeable to Sodium ions to transport the Sodium outside maintaining the
concentration outside and inside..
Action potential - during this this the membrane becomes much more permeable to Sodium ions
which allows the huge of Sodium inside the neuron in a short time making the charge opposite
direction with comparison to outside.. The Potassium ions moves outside of the neuron thus
creating action potential....

dark area with no light source. Hence seeds in the dark is control group in this experiment..
21. What is the relationship between the maximum size of aggregates a.pdfbirajdar2
21. What is the relationship between the maximum size of aggregates and concrete strengths for
the same water-cement ratio 22. Certain harmful materias in aggregates, such as such as some
shales, will cause popouts. What are the mechanisms of the popouts? 23. What are the minerals
that are considered low shrinkage aggregates? 24. List three negative effects of organic
impurities in concrete
Solution
21) Relationship between maximum size of aggregates and concrete compreesive strength:
Compressive strength of concrete depends on the aggreagte strength not necessarily on the
aggragate size. However, with an increase in size of the aggreagte to the maximum the
consumption of water-cement ratio decreases, thereby the density of concrete increases. With
increase in density, the compressive strength increases.
The surface texture of aggregate can either be smooth or rough. A smooth surface can improve
the workability, yet a rougher surface generates a stronger bond between the paste and the
agggregates creating a higher strength. Angular and elongated aggregates have higher surface to
volume ratio, better bond characteristics but require more cement paste to produce a workable
mixture. So for the same water-cement ratio, smooth aggregates are preferred to produce higher
compressive strength.
22) Mechanisms of popouts:
Shales have been found to be montmorillonitic. Popouts could be attributed to the pressures
generated by the absorption of water by the monmorillonite.
The reaction between cement alkalis and the reactive shale particles form an alkali-silica gel at
the surface of the reacted particle. The quantity of gel produced from a single reactive particle,
and the rate at which it forms, will be the greatest if the particles are exposed to high-alkali
concentrations. Once formed, the alkali silica gel absorbs water and start to swell. The swollen
gel occupies the available pore space in the concrete creating pressures, which often causes
popouts.
23) Minerals that are considered low shrinkage aggregates:
Metakalinite: It is a highly reactive material which is formed as a result of roasting of natural
kaolinite at temperatures of 700oC to 900oC.
Zeolite: The source of zeolite formation is due to settlement of volcanic ash and then reaction
with lake salts.
Fly ash: It is a by-product obtained during combustion of coal in thermal power plants.
Silica fumes: It is a by-product of the production of elemental silicon or alloys containing silicon,
also known as condensed silica fume or microsilica.
Slag: Blast furnace slag is a by product of extraction of iron ore. Amongst the mineral
admixtures, slag possesses the highest specific gravity( around 2.8 to 3.0).
Rice hush ash: It is a highly reactive pozzolan obtained by controlled calcination of rice husks.
24) Negative effects of organic impurities:
- Organic impurities derived from decaying vegetation delay the setting time and hardening of
concrete.
- Silt, clay and dust may form a coating on the a.

In summary, there is evidence for an active Wnt/Beta catenin pathway within the vegetal region
of the chick embryo, which is radially distributed around the epiblast. In contrast, the
Tbx6L/cVg1/CMIX system is restricted to the posterior vegetal region of the embryo. The
activities of the two pathways overlap spatially in the posterior marginal zone(PMZ), which thus
becomes a focal structure of early avian development..

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Given below is an issue that you have identified as an issue in a ret.pdf
1. Given below is an issue that you have identified as an issue in a retail company: Assume the
organization is a typical retailer with a corporate network installation. Store networks are
connected to the backend servers via the POS machines. Network administrators use Telnet to
access the network and network passwords never expire. Administrators should only access the
network internally. Complete a risk qualification for this organization and identify the following:
Vulnerability: Threats (threat actor and activity): Severity: Likelihood: Sensitivity:
Solution
According to the above corporate network infrastructure, the following risks can be found in
terms of security & Risk Management:
Vulnerability: As authentication credentials and all the commands are sent to the network device
in cleartext format, it could allow for eavesdropping or manipulation of data in transit between
the user and the network device.
Threat: It's a kind of internal abuse.A savvy insider could interpret and steal sensitive
information or credentials of an authorized administrator as it traverses the network.
Severity: Payment card information traverses these n/w devices between the point of sale system
(in the stores) and back-end servers (corporate data centers). If they can get access to the n/w
device, they can have the full control or access to view any of this sensitive data.
Likelihood: Although it is possible to view any data in a Telnet session, it is not trivial to sniff
traffic on a switched network. The attacker would need to be in the path of the communication
between the network device and the administrator, or the attacker would need to exploit a
vulnerability on another network device in the path. Additionally, the attacker would need some
knowledge of the network device technology in order to capture and view data traversing the
network device after gaining access. The probability of the attacker gaining access once the
credentials have been stolen is further reduced by the use of Access Control Lists (ACLs) on the
network device to limit Telnet connections to certain source IP addresses used by network
administrator’s workstations. Given that the password never expires and is therefore likely not
ever to be changed, the chance of interception and successful exploitation increases over time.
The attack vector with the most the highest probability of success would be from the store
network.
Sensitivity: A breach of this sort would require the organization to publicly report the incident,
costing the company over $500,000 directly in the form of fines and lawsuits and also indirectly
when approximately 10% of clients switch their business to a competitor.
