Network security is an important part of protecting confidential data. All the security software in the world won’t help if the network it’s installed on isn’t kept safe by the people who access it. The only way to secure your networks it to make sure everyone using it practices good habits. There are many different behaviors that can be taught to prevent users from doing things that leave the network less secure.
Passwords are a very basic type of access control. Administrators need to make sure there are minimum settings for password creation. Having a minimal amount of characters is a good start. Studies show that passwords of at least fifteen characters are optimal. It’s also a good idea to include special characters, numbers, and capital letters as well.
Firewalls and security software help keep the network safe. When users want to visit sites outside the network they might consider disabling that software. Everyone should be taught that disabling this software makes the entire system vulnerable, not just their computer. If all else fails, it might be necessary to remove the ability to disable security software.
Physical connections should be checked often. Most software attacks can be stopped easily. Unusual activity on the network can be detected and stopped with a combination of software and technical expertise. Physical connections can be much harder to track. Users should get in the habit of checking their physical network connections to make sure there’s no new hardware connected.
Wireless settings can be configured easily by almost anyone with network access. WiFi networks are especially easy to hack. Administrators shouldn’t have to restrict access based on who has control over wireless settings. Everyone should learn about how wireless settings can put the entire network at risk.
Backups should be performed often. Preventing spyware infections requires cleaning out the system regularly. If files aren’t backed up they might be lost during cleaning. Employees should get in the habit of backing up their files so the system can be cleaned as necessary. Backups can also be scheduled by users either through the operating system or the service used for storing the files online.
