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
