An intrusion detection software is a software that helps you monitor your system and/or network for policy violations or any other malicious activity. If any are detected, the intrusion detection software will report back to you, giving you a number of solutions to handle the situation. After the detection is made the software will try to stop the possible incidents or, if that is not possible, to isolate the problem so it wouldn’t cause any additional damage to your system and network.
The primary use of the intrusion detection software is to detect any possible events that will affect your system’s well being, to record all the information available, to try to stop them and to notify the system administrators about the incidents. Also, intrusion detection software is used by large companies and organizations for purposes like recognizing problems with security policies, stopping people from breaking the security policies or documenting about possible threats. Nowadays, with the progress made by technology, nearly every company or organization is required to use the intrusion detection software in order to keep their private valuable information safe from outside attackers.
Using the intrusion detection software will not require any special skills, but if you don’t know a lot about computers it is always best to notify the person responsible with the administration. In case a detection is made, the software will inform you about it and will specify the type of activity detected. The terminology used by the intrusion detection software is simple and easy to use if you have a bit of a knowledge about computers.
Here are some examples:
- Alert – reports that the system in under attack
- True Positive – an attack that produces an alarm
- True Negative – no attack has occurred and no alarm is triggered
- False Positive – an event triggering an alarm when no attack was produced
- False Negative – an attack not being detected
- Site Policy – a set of regulations that will guide an intrusion detection software’s functioning
The intrusion detection software, like any other software, has some limitations, as the technology advance is very fast and every day new methods to trick the system are discovered. One of the main weaknesses is the high false alarm rate. Many things can generate a false alarm, from software bugs to Internet packets not being read and it is never pleasant to look for a problem where there is none. Another problem is keeping the software up to date. If you are not familiar with the term, you might be in danger. Many attacks target outdated versions of the intrusion detection software, so it is always important to keep it updated. If you don’t know how, ask for help. You can never be to careful about it.
In conclusion, it is always important to use an intrusion detection software in order to secure the privacy of your information. Whether you are a domestic user or part of a larger organization, the risks are the same. People are always trying to access private information and the intrusion detection software is a useful tool that helps you keep them away.
