Summary
Computer security is about protecting computers and networks from threats. Students learn about the importance of security in systems design and the measures used to prevent, detect and respond to threats.
What is computer security
Computer security is information security for computing devices and networks. It covers all the processes and mechanisms to protect computer-based equipment, information and services.
Security and systems design
Security is important when designing a computer system. Many organisations prioritise security improvements to their computer systems.
Security measures
Security involves three processes: threat prevention, detection, and response. These processes use various policies and system components to protect systems and data.
Prevention systems
User account access controls and cryptography protect systems and data. Firewalls are common prevention systems that can shield access to internal network services.
