Firewall’s task is to block attack attempts on a network. Firewall monitors network traffic and blocks all connections coming from untrusted recipients. It allows to stop potential attacks even before they have reached the company’s network and devices in it.
Firewall systems can be divided into three types:
- Open source firewalls – we implement this type of firewall on Windows and Linux systems.
- Commercial firewalls – dedicated network devices. When selecting the equipment, we use mostly Cisco and Fortinet solutions.
- Firewalls on network active devices – configuration of firewall systems embedded in network devices.
