Intrusion Detection System (IDS) Evasion
Intrusion Detection System (IDS) evasion is a technique that is commonly used in the field of computer security. To put it simply, an IDS is a security system that is designed to detect and prevent unauthorized access to a network or a computer system. IDS evasion is the act of circumventing or bypassing the security measures that are put in place by an IDS.
There are many different techniques that can be used to avoid detection by an IDS. One of the most common techniques is called “signature mutation”. This involves making small changes to the attack code in order to avoid detection by the IDS’s signature-based detection system. Another technique is known as “protocol-level evasion”. This involves exploiting weaknesses in the network protocols that the IDS is designed to monitor.
Overall, IDS evasion is a major concern for security experts, as it allows attackers to sneak past security systems undetected. As a result, many security professionals put a great deal of effort into developing and deploying IDS systems that are capable of keeping up with the latest evasion techniques.
