Content-based signature analysis is the type of attack signature analysis performed by Anderson in

the above scenario. Content-based signature analysis is a technique that analyzes packet header

fields such as IP options, IP protocols, IP fragmentation flags, offset, and identification to check

whether any fields are altered in transit. Content-based signature analysis can help detect attacks

that manipulate packet headers to evade detection or exploit vulnerabilities . Context-based

signature analysis is a technique that analyzes packet payloads such as application data or commands

to check whether they match any known attack patterns or signatures. Atomic-signature-based

analysis is a technique that analyzes individual packets to check whether they match any known

attack patterns or signatures. Composite-signature-based analysis is a technique that analyzes

multiple packets or sessions to check whether they match any known attack patterns or signatures.
