You're tasked with securing a corporate network against insider threats. How would you implement strategies to prevent unauthorized access to sensitive data?

Multi-factor authentication (MFA) adds an extra layer of security by requiring users to provide multiple forms of identification before accessing sensitive data. This can prevent unauthorized access even if login credentials are compromised. Strict access control policies limit access based on roles and responsibilities, reducing the risk of unauthorized access. Security awareness training educates employees about potential threats and best practices, but it alone may not prevent unauthorized access. Encryption protects data from being accessed by unauthorized parties, but it doesn't prevent access attempts.
