Cyber Security: Threats and Protection Measures
This page delves into the reasons behind system attacks and various protection measures in cyber security, which is crucial knowledge for BTEC IT Level 3 Unit 11 Cyber Security studies.
Reasons for system attacks include:
- Fun or challenge
- Industrial espionage
- Financial gain
- Personal attacks
- Disruption
- Data or information theft
Definition: Phishing is a term used to describe malicious individuals or groups who scam users through the use of email.
Example: A Man-in-the-Middle (MitM) attack, also known as a hijack attack, is where an attacker secretly relays and possibly alters communications between two parties who believe they are directly communicating with each other.
User access restriction measures include:
- Physical security measures (locks)
- Passwords
- Biometrics
- Two-factor authentication
- Device hardening
- Procedures for backing up and recovering data
- Encryption of stored and transmitted data
Data level protection measures include:
- Firewalls (hardware and software)
- Anti-virus software
Vocabulary: A firewall is a program or hardware device that filters information coming through the internet connection into your private network or computer system.
Highlight: Implementing a combination of user access restrictions and data level protection measures is essential for comprehensive cyber security in digital information systems.
