Study Notes
Information Security Tools
- Tools can range from software to hardware like door locks.
- Tools aim to prevent unauthorized access to confidential information.
- Procedures are important for understanding how to use security tools effectively.
Threat Actors
- Threat actors are individuals or groups that pose a threat to information security.
Fundamental Security Principles
- Layering: Multiple defenses are used to create a barrier against attacks. This approach, also known as defense-in-depth, provides comprehensive protection.
- Limiting: Restricting access to information and resources based on need-to-know principles.
- Diversity: Using a variety of security tools and techniques to make it harder for attackers to exploit vulnerabilities.
- Obscurity: Making it difficult for attackers to understand how systems work or to identify vulnerabilities.
- Simplicity: Designing systems in a way that is easy to understand and secure.
