How Does Network Security Work?

To understand What is network security?, it helps to understand that no single solution protects you from a variety of threats. You need multiple layers of security. If one fails, others still stand.

Network security components often include:

Anti-virus and anti-spyware
Firewall, to block unauthorized access to your network
Intrusion prevention systems (IPS), to identify fast-spreading threats, such as zero-day or zero-hour attacks
Virtual Private Networks (VPNs), to provide secure remote access
