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:

1. Fun or challenge
2. Industrial espionage
3. Financial gain
4. Personal attacks
5. Disruption
6. 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:

1. Physical security measures (locks)
2. Passwords
3. Biometrics
4. Two-factor authentication
5. Device hardening
6. Procedures for backing up and recovering data
7. Encryption of stored and transmitted data

Data level protection measures include:

1. Firewalls (hardware and software)
2. 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.
