Hardware

Hardware knowledge in IT and cybersecurity involves understanding computer components, their interactions, and security implications at the physical and firmware level.

Core Components

• Processors (CPU) - Architecture, security features, vulnerabilities
• Memory (RAM) - Types, management, security considerations
• Storage - HDDs, SSDs, encryption capabilities
• Motherboards - BIOS/UEFI, TPM, secure boot
• Network Hardware - NICs, switches, routers, firewalls

Security Considerations

• Hardware security modules (HSM)
• Trusted Platform Module (TPM)
• Secure boot and measured boot
• Hardware-based encryption
• Physical security and tamper protection

Hardware Vulnerabilities

• Side-channel attacks (Spectre, Meltdown)
• Firmware attacks
• Supply chain compromise
• Physical access attacks
• Hardware implants

Skills Application

• System building and troubleshooting
• Hardware forensics
• Embedded systems security
• IoT device security
• Data center security
