Cyber security Fundamentals - Confidentiality
Confidentiality is about preventing the disclosure of data to unauthorized parties. It also means trying to keep the identity of authorized parties involved in sharing and holding data private and anonymous.
Often confidentiality is compromised by cracking poorly encrypted data, Man-in-the-middle (MITM) attacks, disclosing sensitive data. Standard measures to establish confidentiality include:
Data encryption
Two-factor authentication
Biometric verification
Security tokens
Integrity
Integrity refers to protecting information from being modified by unauthorized parties. Standard measures to guarantee integrity include:
Cryptographic checksums
Using file permissions
Uninterrupted power supplies
Data backups
Availability
Availability is making sure that authorized parties are able to access the information when needed.
Standard measures to guarantee availability include:
Backing up data to external drives
Implementing firewalls
Having backup power supplies
Data redundancy
