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.
