System design should be kept secret to improve security.

The security architecture should be made publicly available. (correct)

Security should depend on the secrecy of the system's design.

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.
