Network security is appreciated the most when a security breach happens and trouble strikes. It is not necessary to say that this is not the way to go. Instead, you should focus your efforts on how to improve your security in order to prevent security disasters from happening. Here are some simple, yet frequently forgotten ideas how to secure your network:

  1. Security policies are a must. Many people hate when rules and regulations limit them but security policies are too important to be ignored and they are something you can’t do without.

  2. Security starts with physical security. Physical access control to your premises is very important because when everybody can walk around your facilities, this can cause more problems than even the most severe remote attack.

  3. The least privilege rule. It is a basic rule that the best security is achieved when users have the least privilege required in order to do their jobs. That’s why you shouldn’t be generous with giving them rights because this can be easily misused – intentionally or unintentionally.

  4. A network is as secure as its weakest part is. With network security, there are no averages. If you have made 99% of your network as secure as a fortress but you have one tiny gap you have left unprotected, this is all it takes to take your whole network down.

  5. Control devices. The use of mobile devices and removable media, such as USBs, DVDs, external hard drives is becoming very common but in fact they offer limitless opportunities for misuse. What is more, you often don’t have control over the way your users use their mobile devices and removable media, which makes things worse.

  6. Weak passwords. Passwords are one of the keys to any security policy. It is true that password-protection is not the most reliable protection but it is the best one can afford. Weak passwords (or even worse – no passwords at all) are a great security risk. Passwords, which are know by everybody, aren’t better and you should also fight with the desire of your users to share their passwords with friends and colleagues.

  7. Malware. Viruses and other pests are so widespread that it is hard to figure out how somebody might not take the necessary precautions against then. Still, it is a fact that many companies and individuals do not take this thread in earnest and do not protect themselves against this. Needless to say, the damages can be very, very severe.

These basic recommendations are far from a complete reference how to secure your network but they are a good starting point and if you don’t implement at least them, you should start right away.
