Question

What is file security and how is it achieved?

Hint:

File security protects data integrity and privacy by controlling access and encrypting sensitive information.

Answer 1

File security refers to protecting computer files from unauthorized access, alteration, deletion, or theft. It ensures that sensitive data is safe and only accessible by authorized users. File security is achieved through:

• Access Permissions: Setting read, write, and execute permissions to restrict who can view or modify files.
• Encryption: Encoding file contents so that only users with the decryption key can read them.
• Authentication: Verifying the identity of users before granting access.
• Backup and Recovery: Regularly saving copies of files to prevent data loss.
• Antivirus and Anti-malware: Protecting files from malicious software attacks.
