Introduction
Knight Inc will be growing in the next few years and it will require robust and reliable network infrastructure. The company will need to be sure that it data can be accessed and handled in an environment that is safe and technically sound. The solutions will need to be up to date and be updated regularly. Security is very important and it will be paid the utmost attention to ensure that no bad elements are allowed into the network to cause damage and endanger the company’s data and infrastructure.
Logical and Physical Topographical Layout
Star topology will be used for the physical network. This is where all devices in a network are connected to a central hub. All resources are drawn from this hub including bandwidth that allows access to cloud resources. Star topology simplifies the matter of network management as everything can be deployed from the central hub(Shinde, 2014).
Bus topology will be used for the logical network. It is a topology where a backbone is the anchor on which computers connect to and request data and other resources. The logical network exists on a different subnet and as such can have different topology than the physical network. Computers are identified by IP addresses. Bus topology is good as it provides the computers with capabilities to access data as they need it by simply requesting (Shinde, 2014).

Incorrectly deployed and configured firewalls and intrusion detection systems can be vulnerabilities to their networks. Given that they are meant to monitor traffic coming to and from the network and determine the harmful ones, this will not be accomplished. This makes it easy for malware to access the system. Fixing this requires that the firewall and the intrusion detection system be regularly checked for any signs of vulnerabilities and be fixed accordingly. (Peltier, 2013).
New devices like smartphones and tablets can also cause problems for the network. These are usually used when the company has its operations hosted on a cloud. This then allows for access to data from a variety of devices, which is every device that can access the internet. For companies that allow its employees to use personal devices to access work data, they are especially vulnerable. Viruses could easily be uploaded to the cloud without even the device owner realizing. The fix is to ensure that all mobile devices used to access the cloud are company issued so that they can be assessed and equipped with the necessary security measures (Peltier, 2013).
Old credentials could be used to access the network discreetly without raising suspicions, these could be the credentials of employees that have lef ...

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.

2. Network Security is the security provided to a
network from unauthorized access and risks.
It is the duty of network administrators to adopt
preventive measures to protect their networks from
potential security threats.
Network Security refers to any activity designed
to protect the usability and integrity of your network
and data.
3. Network security consists of the provisions
and policies adopted by a network administrator to
prevent and monitor unauthorized access, misuse,
modification, or denial of a computer network and
network-accessible resources.
Network security involves the authorization of
access to data in a network, which is controlled by
the network administrator.
It targets a variety of threats and stop them from
entering or spreading on your network.
4. Protect vital information while still allowing access to
those who need it
Trade secrets, medical records, etc.
Provide authentication and access control for
resources
Guarantee availability of resources
Ex: 5 9’s (99.999% reliability)
5.
6. The function of "Confidentiality" is in protecting
precious business data from unauthorized
persons.
Confidentiality part of Network Security makes
sure that the data is available only to intended and
authorized persons.
Access to business data should be only for those
individuals who are permitted to use that data.
7. Authentication is the process of determining
whether someone or something is, in fact, who or
what it is declared to be.
Ensures that whoever supplies or accesses
sensitive data is an authorized party.
8. At a minimum level, all network devices should
have username password authentication.
The password should be non-trivial ( at least 10
characters, mixed alphabets, numbers and
symbols ).
9. Integrity aims at maintaining and assuring the
accuracy and consistency of data.
The function of Integrity is to make sure that the
date is accurate and reliable and is not changed
by unauthorized persons or hackers.
The data received by the recipient must be exactly
same as the data sent from the sender, without
change in even single bit of data.
10. The sender and receiver are to be able prove that
they sent or did not send or received a message.
Ensures that the recipient actually received the
message or data and sender sent the message or
data.
11. Limits and control access to certain system
applications to certain users.
Network access control is a method of enhancing
the security of a private organization network by
restricting the availability of network resources to
endpoint device that comply with the organization
security policy.
12. The function of "Availability" in Network Security is
to make sure that the Data, Network Resources or
Network Services are continuously available to the
legitimate users, whenever they require it.
13. The network security model is a model that
determines how the information is sent securely
over a communication line.
14. The components of network security model :
Sender
Receiver
Communication Lines
Encryption / Decryption
Trusted Third Party
15. Network security is an important and critical issue
that all computer systems need to have
implemented some sort of security control.
Without having security, sensitive information can
be easily gained, so it is important that we prevent,
detect and correct security issues.
