Firmware Security
The protection of firmware from tampering and exploitation by cybercriminals.
Understanding Firmware Security
Firmware serves as the foundation for hardware initialization and boot processes. Because it exists at a low level, attackers can exploit flaws, misconfigurations, or outdated firmware to gain persistent access to a device. Traditional security tools, such as antivirus and firewalls, often fail to detect firmware-based threats, making firmware security a critical area of focus.
Common Firmware Attack Vectors
Firmware Rootkits – Malicious software that embeds itself within firmware to persist across reboots.
BIOS/UEFI Exploits – Vulnerabilities in boot firmware allow attackers to modify startup processes.
Supply Chain Attacks – Attackers infect firmware during manufacturing or software updates.
Privilege Escalation Attacks – Exploits firmware flaws to bypass OS security controls.
Common Applications of Firmware Security
1. Protecting Enterprise Hardware
Secures servers, workstations, and endpoint devices from low-level attacks.
2. IoT and Embedded Systems Security
Ensures smart home devices, medical equipment, and automotive firmware are not compromised.
3. Preventing Persistent Malware
Stops malicious actors from embedding malware at the firmware level for long-term access.
