What is a rootkit?

• A. A type of hardware firewall
• B. A method for encrypting data
• C. A type of malware that hides its presence
• D. A standard for data storage

Answer: (C)

A rootkit is a type of malware designed to gain unauthorized access to a computer or network while masking its presence. It operates at a low level in the system, often integrating itself into the operating system's kernel or installing malicious applications that can hide processes, files, and other system activity. By doing so, it allows an attacker to maintain control over a system covertly. This stealthy behavior makes rootkits particularly dangerous, as they can evade detection by conventional security software and users alike, allowing the attacker to execute malicious actions, steal data, or exploit the system for further attacks without being noticed. Understanding rootkits is crucial for implementing effective security measures and mitigation strategies in any system.
