1. Firewall can strengthen security policy
Because there are millions of people collecting and exchanging information there every day on the Internet. industrial firewall are “traffic cops” designed to prevent undesirable phenomena, enforcing a site’s security policy and allowing only “approved” and rule-compliant requests to pass through.
2, the firewall can effectively record the activities on the Internet
Firewalls are ideal for collecting information about system and network usage and misuse because all information going in and out must pass through them.
3. Firewall restricts exposed user points
Firewalls can be used to separate one network segment from another in a network. In this way, problems affecting one network segment can be prevented from spreading through the entire network.
4. A firewall is a checkpoint for security policies
All incoming and outgoing information must pass through the firewall, and the firewall becomes a checkpoint for security issues, allowing suspicious access to be denied the door.
