Question

How does IDS signature analysis work?

a. It identifies anomalies in network traffic.
b. It matches patterns in data against known attack signatures.
c. It encrypts data for secure transmission.
d. It monitors physical access to a network.

Answer 1

IDS signature analysis is a process used by Intrusion Detection Systems (IDS) to detect and identify network attacks. It works by matching patterns in data against known attack signatures.

Step-by-step explanation:

IDS signature analysis is a process used by Intrusion Detection Systems (IDS) to detect and identify network attacks. It works by matching patterns in data against known attack signatures. IDS signatures are patterns or specific characteristics of known attacks that have been identified and documented.

For example, if an IDS receives network traffic that matches a known attack signature, it can trigger an alert to notify system administrators of the potential attack. This enables them to take appropriate action to mitigate the threat.

Some IDS systems also use anomaly detection, which identifies network traffic that deviates from normal behavior. This helps detect new or unknown attacks that may not have a known signature.
