Hardware,Software,and Os security

Hardware

Physical components of a computer system (processors, memory, and storage devices).

Threats to Hardware systems:

1.Physical attacks: unauthorized access or theft of hardware components

2.Counterfeit Components: malicious parts in the supply chain risk hardware reliability and security.

3. Hardware Trojans: hidden malicious circuits can leak sensitive data.

4. Side-channel attacks: attackers exploit power consumption.

Security practices for hardware:

1. Secure boot processes

2. Trusted platform modules

3. Hardware security keys

4. Firmware and virtualization security

Software security

Protects programs and applications running on a computer system from vulnerabilities, bugs, and potential exploits.

Threats to software systems:

Exploitation of vulnerabilities: attackers exploit software vulnerabilities.

Malware threats.

Code injection attacks

Logic bombs
