majiayu000 Authentication Validator
This skill provides automated assistance for authentication validator tasks.
Overview
This skill allows Claude to assess the security of authentication mechanisms in a system or application. It provides a detailed report highlighting potential vulnerabilities and offering recommendations for improvement based on established security principles.
How It Works
- Initiate Validation: Upon receiving a trigger phrase, the skill activates the
authentication-validatorplugin. - Analyze Authentication Methods: The plugin examines the implemented authentication methods, such as JWT, OAuth, session-based, or API keys.
- Generate Security Report: The plugin generates a comprehensive report outlining potential vulnerabilities and recommended fixes related to password security, session management, token security (JWT), multi-factor authentication, and account security.
When to Use This Skill
This skill activates when you need to:
- Assess the security of an application's authentication implementation.
- Identify vulnerabilities in password policies and session management.
- Evaluate the security of JWT tokens and MFA implementation.
- Ensure compliance with security best practices and industry standards.
Examples
Example 1: Assessing JWT Security
User request: "validate authentication for jwt implementation"
The skill will:
- Activate the
authentication-validatorplugin. - Analyze the JWT implementation, checking for strong signing algorithms, proper expiration claims, and audience/issuer validation.
- Generate a report highlighting any vulnerabilities and recommending best practices for JWT security.
Example 2: Checking Session Security
User request: "authcheck session cookies"
The skill will:
- Activate the
authentication-validatorplugin. - Analyze the session cookie settings, including HttpOnly, Secure, and SameSite attributes.
- Generate a report outlining any potential session fixation or CSRF vulnerabilities and recommending appropriate countermeasures.
Best Practices
- Password Hashing: Always use strong hashing algorithms like bcrypt or Argon2 with appropriate salt generation.
- Token Expiration: Implement short-lived access tokens and refresh token rotation for enhanced security.
- Multi-Factor Authentication: Encourage or enforce MFA to mitigate the risk of password compromise.
Integration
This skill can be used in conjunction with other security-related plugins to provide a comprehensive security assessment of an application. For example, it can be used alongside a code analysis plugin to identify potential code-level vulnerabilities related to authentication.
