Deepen your knowledge of CMS security by exploring key concepts in authentication methods, role management, and strategies to prevent common vulnerabilities. This quiz helps users understand best practices and risks associated with safeguarding content management systems.
Which method best enhances login security in a CMS by requiring users to provide a one-time code from a mobile device after entering their password?
Explanation: Multifactor authentication adds a layer of security by requiring something the user knows (password) and something the user has (one-time code), making unauthorized access significantly harder. Plaintext login is insecure because passwords are exposed, and single sign-in does not provide the additional security layer. Role escalation refers to increasing user permissions, which relates to authorization, not authentication.
In a CMS scenario, which user role should only have permission to edit and publish content but not to manage system settings or user accounts?
Explanation: Editors in a CMS can modify and publish content, but they typically lack access to sensitive system or user management settings. Administrators and superusers hold broader system-level permissions, while viewers can only read content. Granting the editor role only content-related access reduces the risk of accidental system changes.
To protect a CMS from SQL injection attacks when processing user-submitted form data, which strategy is the most effective?
Explanation: Prepared statements ensure user inputs are handled safely by separating data from SQL commands, making injection much harder. While increasing password length and limiting login attempts enhance authentication security, they do not address SQL injection. Allowing direct query input is risky and exposes the CMS to attacks.
After a user logs out of a CMS, which measure helps prevent unauthorized access if someone acquires their old session ID?
Explanation: Invalidating the session immediately on logout ensures that stolen session IDs cannot be reused. Storing sessions in cookies permanently and extending the duration make it easier for attackers to hijack sessions. Using predictable session names helps attackers guess valid sessions and should be avoided.
Which technique helps prevent XSS vulnerabilities in a CMS by ensuring that HTML special characters in user input are not executed in the browser?
Explanation: Output encoding transforms special characters like angle brackets into browser-safe representations, preventing scripts from executing. Weak password policies and unrestricted file uploads pose different security risks but do not address XSS. Client-side redirects do not mitigate the impact of malicious scripts embedded via user input.
