Study Notes
Security and Ethics
- Computer and data security is the practice of protecting computer and data from unauthorized access and corruption.
-
Sources of security breaches:
- Malware (viruses, worms, spyware, Trojan horses)
- Poor network implementation
- Lack of ICT policies
- Carelessness
- Hackers, spammers, scammers
-
Malware: malicious programs designed to access or damage a computer without the owner's knowledge.
- Viruses: Attach to programs/files, spreading infections as they travel. Need human action (e.g., running an infected program) to spread.
- Worms: Spread from computer to computer without human intervention, taking advantage of file transport features.
- Trojan horses: Not viruses. Disguised as legitimate applications, but can be destructive. Open backdoors for malicious access.
- Spyware: Malicious software that gathers data about a user and sends it to a third party without consent. Sometimes used legitimately for advertising.
- Poor network implementation: Security vulnerabilities in network setups.
- Poor/lack of ICT policies: Lax or absent network access policies make systems vulnerable.
- Carelessness: Providing personal information without proper security measures.
- Hackers, spammers, scammers: Individuals who use computers to gain unauthorized access, send unwanted messages, or defraud others
