Study Notes
Network Segmentation and Isolation
- Sensitive systems are placed on separate networks to limit access.
- Segmentation: Systems within the network can communicate with restrictions to systems outside the network.
- Isolation: Complete separation from external networks.
Rule-Based Access Control (RBAC)
- Uses a set of rules or access control lists (ACLs) to define access.
- Checks access attempts to an object against rules.
- Firewalls use rule-based access control.
Attribute-Based Access Control (ABAC)
- Policies are based on user attributes.
- Creates complex rulesets based on attribute combinations.
- Flexible due to context-specific attribute settings.
- Complex to manage effectively.
- Useful for enterprise systems with varying user roles and rights.
- Also used in databases, content management systems, microservices, and APIs.
Time-of-Day Restrictions
- Limit the time of day when activities can occur.
- Windows example: Logon hours set in Active Directory to enforce work hours.
- Prevents account misuse and unauthorized access.
Least Privilege
- Users and accounts should have the minimum permissions needed for their roles.
- A core concept throughout information security practices.
- Essential for designing permission and access schemes.
