A security audit systematically evaluates an organization’s information systems and security policies to assess their effectiveness, identify vulnerabilities, and recommend improvements.
14. What steps would you take if you discovered a security breach?
Isolate affected systems, contain the breach, notify relevant parties, investigate the incident, remediate vulnerabilities, and implement measures to prevent future breaches.
15. What is social engineering? Give an example.
Social engineering manipulates individuals to disclose confidential information or perform actions for malicious purposes.
Example: Pretending to be a trusted colleague and asking for login credentials over the phone.
16. What are cookies in a web browser?
Cookies are stored by websites on a user’s device. They are used to track user preferences, session information, and provide a personalized browsing experience.
17. What is a DDoS attack and how does it work?
A Distributed Denial of Service (DDoS) attack inundates a target server or network with excessive traffic originating from numerous sources, making it inaccessible to genuine users.
18. Explain what a security policy is.
A security policy comprises a collection of formally documented regulations, recommendations, and protocols that delineate an organization’s methods to safeguard its information, assets, and technological resources.
19. What is the difference between symmetric and asymmetric encryption?
- Symmetric Encryption uses a similar key for encryption and decryption.
- Asymmetric Encryption employs a pair of keys, one public and one private. Data that is encrypted with one key can only be deciphered using the complementary key.
20. How can you prevent a Man-In-The-Middle attack?
Use secure communication protocols, verify digital certificates, and avoid public Wi-Fi for sensitive transactions. Implementing strong encryption also helps.
