Solutions to Computer Network Security Problems
This section talks about solutions to computer network security problems when you have an existing network. It also applies to people who are considering building small networks.
First of all, you need to develop a plan to assess the vulnerabilities of your network. A vulnerability assessment plan should cover the key areas that, if affected, can bring down the network or create huge data loss. These items include
1 - Server protection (the main computer in case of peer to peer networks),
2 - Firewalls and antivirus on the server,
3 - The method your server employs to communicate with other computers, and
4 - How other peripherals on the network (computers, printers, etc) can pose a danger to the network.
Please note that this list is not comprehensive. There can be several other points to consider - based on your network type and configuration.
There is some good software available that helps you assess network problems. The software can scan each component of the network and give you a detailed report so that you can work on the vulnerabilities. Some software can go a step further and patch the vulnerabilities. GFI LanGuard is one example.
