Information and efficient communication are two of the most important strategic issues for the success of every business. With the advent of electronic means of communication and storage, more and more businesses have shifted to using data networks to communicate, store information, and to obtain resources. There are different types and levels of network infrastructures…
Almost every medium and large-scale organization has a presence on the Internet and has an organizational network connected to it. Network partitioning at the boundary between the outside Internet and the internal network is essential for network security. Sometimes the inside network (intranet) is referred to as the “trusted” side and the external Internet as…
Network access control is a method of enhancing the security of a private organizational network by restricting the availability of network resources to endpoint devices that comply with the organization’s security policy. A typical network access control scheme comprises of two major components such as Restricted Access and Network Boundary Protection. Restricted Access to the…
Network layer security controls have been used frequently for securing communications, particularly over shared networks such as the Internet because they can provide protection for many applications at once without modifying them. In the earlier chapters, we discussed that many real-time security protocols have evolved for network security ensuring basic tenets of security such as…
What is System Hacking? System hacking is defined as the compromise between computer systems and software to access the target computer and steal or misuse their sensitive information. The malware and the attacker identify and exploit the vulnerability of the computer system to gain unauthorized access. Hacking Linux system Linux is an operating system based on Unix OS created…
What is Cyber Security? Cyber Security is a domain and body of knowledge consisting of technologies, practices, and processes to secure networks, systems, devices, and data from cyber threats, cyberattacks, and unauthorized access. Sometimes, cyber security is also referred to as information technology security; the professionals specializing in this domain are known as cyber security experts….
Cyber Security skills include techniques that help secure unauthorized digital access to various digital component network data and computer systems. Depending on the type of network we are connected to, there are several ways to implement Cyber Security. Cyber Security: Key Skills To defend networks for an organization effectively, you should first understand how they’re being…
What is Cyber Security? Cyber Security is about adding layers of security to computers, devices, systems, and networks to stop attacks. Almost all organizations have a system and framework to deal with cyberattacks, whether they are attempted or successful. A good framework can help detect and identify threats, protect networks and systems, and recover in…
Overview of Cyber Security In the present world where cyber attackers are well equipped with state-of-the-art and sophisticated technologies, the risk for hacks and security breaches is at its peak. For this particular reason, security protocols need to be in place. And what is better than countering hacking with hacking itself. This is where Ethical Hacking comes…
We have seen that rapid growth of Internet has raised a major concern for network security. Several methods have been developed to provide security in the application, transport, or network layer of a network. Many organizations incorporate security measures at higher OSI layers, from application layer all the way down to IP layer. However, one…
