SPECTER refers to which IDS-related concept?

• A. The process by which an attacker confuses the IDS by forcing it to read invalid packets.
• B. An IDS evasion technique that encodes the attack payload so that only the destination can decode it.
• C. A honeypot system.
• D. A firewall rule optimizer.

Answer: (B)

SPECTER is an IDS evasion technique in which the attack payload is encoded (or encrypted) so that the intrusion detection system does not see the recognizable pattern, while the intended destination can decode it. Signature-based IDS look for known patterns in payloads; encoding the content hides those patterns from the IDS, allowing the traffic to pass through. Once it reaches the destination, the payload is decoded back to its usable form, revealing the attack intent. This contrasts with approaches that simply flood or confuse the IDS with malformed packets, or with concepts outside the IDS realm like honeypots or firewall optimization.
