Network Security

What Is Network Security and How Does It Protect You?

There are many network security threats today, the most common include:

  • Viruses, worms, and Trojan horses
  • Spyware and adware
  • Zero-day attacks, also called zero-hour attacks
  • Hacker attacks
  • Denial of service attacks
  • Data interception and theft
  • Identity theft

How Does Network Security Work?

It is not possible that a single solution can protect your systems from very different types of threats. You need to use many layers of security. If one fails, others still stand.

Network security is about two part, hardware and software. The software must be always updated and try to protect you from new threats.

A network security system mainly has many components. They should work together, which minimizes maintenance and improves security.

Here are some of the Network security components:

  • 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
