The Network Security: Definition and Tips

In this post, we can have a look on the networking security issues. Even wars are focused on computers and network, this topic has got immense value. Please check below:

Network security can be defined as a set of policies adopted in order to monitor and prevent unauthorised access, misuse, modification of a computer network and network resources. The network security measures are designed to check the authorisation of access to data in a network and they are manifested by the implementation of secure hardware, and software.

By applying effective network security, a variety of security threats can be identified and prevented from entering or spreading the network.

The Most Common Network Security Threats:

  • Viruses
  • Worms and Trojan horses
  • Spyware and adware
  • Hacker attacks
  • Zero-hour attacks
  • Service denial attacks
  • Data interception
  • Data theft
  • Identity theft
Network security threat -malware

Network Security Strategy:

No single solution can protect from a variety of security threats, so multiple layers of security are required. If a security layer fails, the other ones will protect.

Network security is implemented by means of both hardware and software. The security software must be constantly updated with the latest versions to protect from the emerging threats.

The Common Network Security Components

  • Anti-virus, anti-spyware and anti-malware
  • Firewall, to prevent unauthorised access to the network
  • Intrusion Prevention Systems (IPS), to protect from quick spreading threats like zero-day or zero-hour attacks.
  • Virtual Private Networks (VPNs), for secure remote access
