ECCouncil 212-89 Actual Questions

The port scanning technique that involves resetting the TCP connection between the client and server abruptly before the completion of the three-way handshake, thereby leaving the connection half-open, is known as a Stealth scan (also referred to as a SYN scan). This technique allows the scanner to inquire about the status of a port without establishing a full TCP connection, making the scan less detectible to intrusion detection systems and less likely to be logged by the target. It ' s a method used to discreetly discover open ports on a target machine without establishing a full connection that would be visible in logs.

Anti-forensics refers to techniques used to hinder the forensic analysis of a computer system. By hiding files in slack space, changing file headers, embedding suspicious files in executables, and altering metadata, BadGuy Bob is attempting to make it difficult for forensic analysts to find, analyze, and attribute the malicious activities and data on his laptop. These actions are designed to conceal evidence, manipulate digital artifacts, and obstruct investigations, making them clear examples of anti-forensic techniques. While such actions could be part of broader criminal activities, constituting a felony, and could be seen as adversarial mechanics or legal hostility in specific contexts, the most accurate classification of these techniques is anti-forensics.
