In security terminology, what term refers to a toolkit of software designed to conceal intrusions?

• A. Firewall
• B. Antivirus
• C. Sniffer
• D. Rootkit

Answer: (D)

Rootkits are a toolkit of software designed to hide intrusions by concealing their presence and activities. They typically modify the operating system or use stealth techniques to hide files, processes, network connections, and logs, often operating at kernel level to avoid detection and allow the attacker continued access. This focus on concealment distinguishes rootkits from other security tools: a firewall blocks unauthorized access, antivirus scans for and removes malicious software, and a sniffer captures and analyzes network traffic. Because the primary purpose here is to keep the intrusion hidden, a rootkit is the term that best fits.
