Same as previous post. Network security refers to all the measures and efforts made to protect a network and its data. The components we care about are the same components from computer security (usability, reliability, integrity).

 

Having a secure network not only assures a healthy and constant connectivity on the network, but most important it helps to protect personal information from a hacler attack.

 

To provide protection to a network we need to combine multiple layers for a solution. Each layer containing its own policies and controls. Some popular types of network security are the following:

 

  • Access control
  • Antivirus and antimalware software
  • Behavioral analytics – it analizes activites that deviate from the norm
  • Email security – this is the channel where many infections occur. An email secuiry application blocks incoming attacks
  • Firewalls – set a barrier between your network and outside networks
  • Network segmentation – it is intelligent to classify and restric a network to limit the privilegies and content each segment has.
  • Web security
  • Wireless security
