What does a signature-based IDS use to identify attacks?answerComparison of current statistics to past statisticsStatistical analysis to find unusual deviationsExceeding threshold valuesComparisons to known attack patterns

IDS signatures are usually based off of patterns and not heuristicsQuestion 4AnswerTrueFalse

Which IDS method searches for intrusion or attack attempts by recognizing patterns or identifying entities listed in a database?answerSignature-based IDSHeuristics-based IDSAnomaly-analysis-based IDSStateful-inspection-based IDS

What is the difference between signature based and anomaly-based intrusion detection system (IDS) technologies?a.Signature-based IDS blocks traffic without an appropriate digital signature, while anomaly-based IDS only alerts on traffic that is not originalb.Signature-based IDS blocks attackers that match a malware signature list, while anomaly-based IDS establish a baseline and then look for variations from the baselinec.Signature-based IDS compares the signature in a packet to determine if the signature is authentic, while an anomaly-based IDS looks for odd occurrences on a systemd.Signature-based IDS flags nefarious traffic with a digital signature, while anomaly-based IDS reviews traffic time stamps and alerts on those that do not match the system time

The _____ component of an IDS signature includes network traffic information.1 分headerrule options signature IDaction

What is the main advantage of an Anomaly-based IDS/IPS?It can detect known attack patterns with high accuracyIt can detect unknown attack patterns with high accuracyIt can identify previously unknown and novel attacksIt can identify previously known and novel attacks
