A. B. C. D.security audit.
Answer: A, B, and D are incorrect.
Implementing NIDS and HIDS and configuring firewall to block unauthorized traffic are not examples of.
Penetration testing is a method of evaluating the security of a computer system or network by simulating an attack from a malicious source, known as a Black Hat Hacker, or Cracker.
The process involves an active analysis of the system for any potential vulnerabilities that may result from poor or improper system configuration, known and/or unknown hardware or software flaws, or operational weaknesses in process or technical countermeasures.
This analysis is carried out from the position of a potential attacker, and can involve active exploitation of security vulnerabilities.
Any security issues that are found will be presented to the system owner together with an assessment of their impact and often with a proposal for mitigation or a technical solution.
The intent of a penetration testing is to determine feasibility of an attack and the amount of business impact of a successful exploit, if discovered.
It is a component of a full penetration testing.
Out of the given options, option C, simulating an actual attack on a network, is an example of penetration testing.
Penetration testing is a type of security testing that involves evaluating the security of an information system by simulating an attack on it. The objective of this testing is to identify vulnerabilities and weaknesses in the system's defenses, which can then be addressed to prevent real attacks from succeeding.
Option A, implementing NIDS on a network, is not an example of penetration testing. NIDS (Network Intrusion Detection System) is a system that detects and alerts administrators about potential intrusions in a network. It is a security measure that helps to protect the network from attacks, but it does not involve simulating an attack on the network.
Option B, implementing HIDS on a computer, is also not an example of penetration testing. HIDS (Host Intrusion Detection System) is a security measure that monitors a computer for suspicious activity and alerts administrators if it detects any potential intrusions. It is a useful security measure, but it does not involve simulating an attack on the computer.
Option D, configuring a firewall to block unauthorized traffic, is not an example of penetration testing either. A firewall is a security device that monitors and controls traffic between a network and the internet. Configuring a firewall to block unauthorized traffic is a proactive security measure, but it does not involve simulating an attack on the network.
In summary, penetration testing is a type of security testing that involves simulating an attack on an information system to identify vulnerabilities and weaknesses in its defenses. Therefore, option C, simulating an actual attack on a network, is an example of penetration testing.
