BIOS Security
Techniques to protect a system’s Basic Input/Output System (BIOS) from tampering or malware.
Understanding BIOS Security
BIOS security focuses on protecting the firmware from unauthorized access, tampering, or corruption. Since BIOS operates at a fundamental level, compromising it can allow attackers to maintain persistent control over a system, bypassing traditional security measures. Threat actors often exploit BIOS vulnerabilities to inject malware that persists even after reformatting the hard drive.
Common Attacks
BIOS Rootkits: Malware that hides within the firmware, making detection and removal difficult.
Firmware Injection: Attackers modify BIOS firmware to alter system behavior or install malicious payloads.
BIOS Password Bypass: Methods used to reset or remove BIOS passwords to gain unauthorized access.
Future Trends
Stronger hardware-based root of trust mechanisms.
AI-driven BIOS anomaly detection to identify malicious modifications.
Blockchain-backed integrity verification for BIOS updates.
