29. What is a security awareness training program?
Ans:- A security awareness training program educates employees about cybersecurity best practices, helping them recognize and respond to security threats.
30. What is a Certificate Authority (CA)?
Ans:- A Certificate Authority is a trusted entity that issues digital certificates to validate the identity of individuals, websites, or organizations in online communications.
31. What is the role of intrusion detection and prevention systems (IDPS)?
Ans:- IDPS monitors network or system activities for malicious behavior, helping detect and prevent security incidents.
32. What is a risk assessment in cybersecurity?
Ans:- A risk assessment evaluates potential threats, vulnerabilities, and the impact of security incidents to determine the level of risk an organization faces.
33. What is the principle of least privilege?
Ans:- The principle of least privilege restricts access rights for users to the minimum level necessary for their job responsibilities, reducing the risk of unauthorized access.
34. What is data loss prevention (DLP)?
Ans:- Data loss prevention aims to prevent unauthorized access, use, or disclosure of sensitive information, ensuring data integrity and confidentiality.
35. What is security hygiene?
Ans:- Security hygiene refers to the best practices and habits that individuals and organizations should follow to maintain a secure computing environment.
