Intrusion Detection System - Assignment Example

Intrusion Detection System A system equipped to fight against firewall, malwares, and offers protection against viruses is not novice. This is because protecting the computer against these attacks is an essential part of computer management and protection policy. I agree with this argument of Justin concerning HIDS. HIDS is an intrusion detection system that screens and scrutinizes the internal parts of a computer system, and its own network interface. The system protects against attacks on the computer memory.

QUESTION 2I agree with this argument of David, since a layered defense provide security to a computing system At three different levels with the aim of preventing an attack from a virus, malwares, worms, theft, un-authorized access and other security risks. The three levels are the system, network and application levels. The HIDS, and NIDS are protective mechanisms, in a computing system that detects and prevents efforts of accessing information from an-authorized parties. I agree with the notion that NIDS is widely based, since the computer administrator can install it at various destinations all over the internal computer system.

I agree with the notion that HIDS is installed in a workstation, or server. This is because the system is an agent of the secured host. Due to this, HIDS serves a particular host, and can serve a particular purpose.Question 3 I agree with David’s answer that the methods of security testing are the white, black and gray box testing. However, I do not agree with the answer that the black box testing system involves knowing the architecture and design of the computer before the testing.

Black-box system does not entail any knowledge of the architecture, or the interior workings of the computer system, while white box testing involves knowledge of the architecture and design of the computer system. Grey box system involves testing the computing system with limited knowledge of the system, and not as defined by David. I agree with the notion that the person conducting black box testing is an end user. This is because the person doing the test cannot access the source code of the computing system.

I also agree with the notion that a system designer conducts white box testing. This is because the test requires extensive knowledge on the internal structure and logic of the computer system. I agree with the notion that beta tester perform grey box testing.Question 3(b) I agree with David’s notion that Vulnerability testing seeks to identify weaknesses in a computer system, and on his notions that vulnerability tests seeks to identify the best places to attack a system. I agree with answer concerning penetration testing, and its application.

Question 4 I agree with Kevin’s explanation on white box, black box, and grey box testing. Kevin’s rightfully explains vulnerability and penetration testing.Question 5 I agree with Richards answer on ethnic tensions, and it main cause is the conflicting views of the cultures of different ethnic groups. In United States of America, there are social structures in place to prevent an emergence of armed conflict emanating from ethnic tensions, e.g. equitable distribution of resources, and efficient law enforcement agencies.
