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 is the practice of safeguarding digital files from unauthorized access, modification, erasure, or appropriation. Its purpose is to guarantee that sensitive information remains protected and is only accessible to permitted individuals. File security is implemented via:

• Access Permissions: Establishing read, write, and execute privileges to limit file visibility and modification rights.
• Encryption: Converting file content into a coded format readable only by those possessing the decryption key.
• Authentication: Confirming user identities prior to granting access.
• Backup and Recovery: Implementing routine file duplication to mitigate data loss.
• Antivirus and Anti-malware: Defending files against malicious software threats.
