The Defense Of Layer Security - 991 Words

Cyber attacks target everyone including small companies, large companies, government agencies, executives, and even salespeople. Cyber criminals are using sophisticated methods to gain unauthorized access to information systems to steal sensitive data, Personality Identifiable Information (PII), or even classified materials. Some of the creative methods that attackers use to gain unauthorized access are backdoor programs, social engineering, and Ransomware. Ransomware, as the name implies, is software that encrypts files, and then requires ransom in order for a person to be re-granted access to their restricted files; thus, ransomware is an access denial type of attack that prevents legitimate users from accessing files. While threats and attacks cannot be eliminated, solutions can be applied to reduce the chances of devices getting infected with malware – it is called the defense-in-layers security approach. Defense-in-layers is an approach that advocates for applying security measures in overlapping layers to ensure that the whole security posture is covered. The security layers are to complement each other by ensuring that an unmitigated vulnerability at one layer is mitigated by another control available within another layer. Figure 1 illustrates how the defense-in-layers approach works. 1. Develop a Policy Agencies must develop a policy as the foundation layer for their security program. The policy needs to highlight the key steps the agency is establishing toShow MoreRelatedEssay On Defense-In-Depth Strategy1218 Words   |  5 Pagesstrong defense-in-depth strategies in place. Although they may be strong defense-in-depth strategies, vulnerabilities may be present and used as an advantage point for hackers to gain access to the network. Defense-in-depth strategies will help create risk management to assess certain risks that may be proven as detrimental to a network. The idea behind defense in depth is to manage risk with diverse defensive strategies, so that if one layer of defense turns out to be inadequate, another layer of defenseRead MoreThe Core Layers Of Defense1237 Words   |  5 Pagesand most of them will perform their duties without having security. In addition, the critical missions of a massive interconnected device are security and interoperability. Hackers will use more complex tools and techniques to breach the network system. Hence, companies should establish strong security countermeasures and the best approach to provide better security by deploying a multilayer approach which is called Defense in Depth.

Defense in depth is a good practice to follow, this is having more than one form of defense to break through. This will either slow down an attacker or discourage them. It is a great strategy because having several layers of defense makes it more difficult for an attacker to breach the network. One critical security device and layer of defense to have on the organizations network is an IntrusionRead MoreThe Threat Of Network Security925 Words   |  4 PagesThere are threats to network security that can compromise your computer systems. Viruses are one of the top security threats in the technology industry. A virus is a program or a code that is loaded into your computer system without your knowledge will run against your wishes (Beal, n.d). Viruses can also replicate themselves. All computer viruses are manmade and a virus can make a copy of itself several times and easy to create (Beal, n.d).
