Study Notes
Fail-Safe Defaults Principle
- Default configurations of systems should deny access unless explicitly granted, minimizing potential vulnerabilities.
- New user accounts in operating systems should be created with the least permissions necessary for essential functions.
Complete Mediation Principle
- This principle requires that every access to a resource must be checked against the current authorization state, ensuring ongoing security.
- Storing results from prior authorization checks may lead to unauthorized access if changes in roles or permissions are not updated.
Open Design Principle
- Advocates for systems to be designed with transparency, allowing for inspection of their structure and security mechanisms.
- Contrasts with 'security by obscurity', which relies solely on keeping system details secret to maintain security.
Virus and Spyware Protection Policy
- Aims to safeguard systems from malicious software by outlining preventive measures and response strategies to threats.
Resource Protection and Peripheral Management Policy
- Encompasses security measures designed to protect system resources from unauthorized applications and manage the access of peripheral devices.
Firewall Policy
- Primarily focuses on controlling network traffic by regulating inbound and outbound data, thereby protecting systems from unauthorized access.
Intrusion Prevention Policy
- Key function is to proactively identify and respond to potential threats or unauthorized access attempts to maintain system integrity.
LiveUpdate Policy
- May include both LiveUpdate Content Policy and LiveUpdate Setting Policy to ensure that systems receive timely updates and maintain security relevance.
Application and Device Control Policy
- Seeks to manage and restrict how applications interact with system resources and control the usage of devices connected to the network.
Principle of Separation of Privilege
- Requires multiple conditions or credentials for gaining access to sensitive resources, thereby reducing risk through diverse authentication methods.
Principle of Least Privilege
- Limits user permissions to only what is necessary for their role, minimizing potential exposure to security threats.
- Enforcing this principle significantly strengthens cybersecurity by reducing attack surfaces.
Limited Access Permissions
- System entities must have restricted access to prevent misuse, limit vulnerabilities, and mitigate the impact of potential incidents.
Revocation of Elevated Rights
- Once higher-level rights associated with a user identity are deemed unnecessary, those privileges should be revoked promptly to minimize risk exposure.
Contribution of Separation of Privilege
- By ensuring that no single entity has unrestricted access, this principle enhances security measures, making unauthorized access more difficult.
