- It is used to protect sensitive data both in transit and at rest.
- Common encryption methods include AES (Advanced Encryption Standard) and RSA (Rivest-Shamir-Adleman).
- Two-Factor Authentication (2FA)
- 2FA adds an extra layer of security by requiring two forms of identification before access is granted.
- This usually includes something you know (password) and something you have (mobile device for OTP).
- 2FA is widely used in online banking, email services, and secure systems.
- Biometric Authentication
- Biometric authentication uses unique biological traits such as fingerprints, retina scans, or facial recognition for identification.

- Commonly used in smartphones, secure facilities, and high-security areas.
- Antivirus Software
- Antivirus software is designed to detect, prevent, and remove malware, including viruses, worms, and trojans.
- Regular updates are essential for antivirus software to protect against the latest threats.
