Intrusion Detection Systems (IDS) are security tools that monitor network traffic or system activity for signs of potential threats or malicious behavior. There are two primary types of IDS: knowledge-based IDS and behavior-based IDS.
Knowledge-based IDS (KIDS), also known as signature-based IDS, uses a database of known attack signatures to identify potential threats. Attack signatures are patterns of network activity or system behavior associated with known attack methods. When network traffic or system activity matches a known attack signature, the KIDS generates an alert or takes other predefined actions to block the attack.
Behavior-based IDS (BIDS) uses a baseline of "normal" activity to identify deviations from normal behavior that may indicate an attack. BIDS can use various techniques to establish a baseline, such as statistical analysis or machine learning algorithms. Once the baseline is established, BIDS can detect abnormal patterns of network activity or system behavior and generate alerts or take other actions to mitigate potential threats.
Answer options:
A. signature-based IDS and statistical anomaly-based IDS, respectively This option is incorrect because it incorrectly identifies KIDS as statistical anomaly-based IDS. KIDS is actually signature-based IDS, as mentioned earlier.
B. signature-based IDS and dynamic anomaly-based IDS, respectively This option is incorrect because it incorrectly identifies BIDS as dynamic anomaly-based IDS. BIDS may use dynamic anomaly detection techniques, but it is not limited to that method.
C. anomaly-based IDS and statistical-based IDS, respectively This option is incorrect because it uses generic terms that do not accurately reflect the specific types of IDS being discussed.
D. signature-based IDS and motion anomaly-based IDS, respectively. This option is incorrect because it introduces a new term "motion anomaly-based IDS," which is not a commonly used term in the field of IDS.
In summary, the correct answer is option A: signature-based IDS and statistical anomaly-based IDS, respectively.
