Study Notes

Virtual Private Networks (VPN)

Relays communications via the Internet while maintaining privacy.
Encrypts data during transmission, securing information from interception.
Decrypts data at the destination for authorized users.
Enhances security by encrypting both originating and receiving network addresses.

Prevention of Cyber Attacks

Complete security from attacks is unachievable for any organization.
Emphasize a layered security approach to deter attackers.
If one layer is breached, additional layers serve as obstacles, making attacks more challenging.

Security Measures

Firewall
- Restricts network access in accordance with the organization's defined access policy.
Intrusion Detection System (IDS)
- Actively monitors system and network resources for suspicious activities and potential breaches.
Antivirus Software
- Detects threats by scanning for known virus signatures, which are unique byte sequences identifying specific viruses.
Virus signatures play a crucial role in recognizing and countering malware infections.
