When a user logs on to his account on the company service and finds that there has been changes made to the settings, It used to be that the first thing that would enter the his mind is that there must be some sort of bug or error in the system. However, nowadays, it would be foolish not to consider that there might have been a breach in the network and that a hacker might have been able to gain access to your account and therefore, the files that you have permission to access and modify as well.
Regardless of whether you work for or own a small, medium, or large-scale corporation. The fact remains the same that there is a risk of intrusion every single day you’re in operation. If you have poor security measures in place, then you increase the odds of having some hacker try to gain access into your system or network.
What is an Intrusion Prevention Service?
Intrusion prevention services work by monitoring the activities being done on the network or server. When a malicious or suspicious action has been done, a report will be generated and sent off to the management station. This is similar in function to intrusion detection services. The main difference is that these services also have a preventive measure in place: aside from the report, intrusion prevention systems work to block or stop such activities in order to prevent a breach.
Intrusion prevention services are basically extensions of intrusion detection services as both monitor the system traffic and network while being on the lookout for any strange activity. Intrusion prevention services are commonly placed in-line so that they can actively block and stop intrusions, once they have been detected.
Methods of Detection with an Intrusion Prevention Service
There are basically three modes of detection being used by most intrusion prevention services. They are as followed: signature-based detection, statistical anomaly-based detection, and stateful protocol analysis detection. They differ on the mode with which they compare network traffic to standards in order to identify whether there has been a breach in security or not.
Signature-based Detection in Intrusion Prevention Services
In this method, signatures are analyzed. Signatures are defined as attack patterns that have been previously noted down and configured into the system. The network pattern is continuously monitored and the activity compared to the signatures. The intrusion prevention service kicks into action once a match has been made. These signatures are either exploit-based or vulnerability-basd.
Statistical Anomaly-based Detection in Intrusion Prevention Services
In the statistical method, the average network traffic conditions are gathered and summarized. A baseline of the activity is then created. Once the baseline has been obtained, then the system will sample the network traffic at regular intervals. Statistical analysis is used in order to compare the obtained samples with the baseline values.
Stateful Protocol Analysis Detection
In this method deviations of the network traffic pitted against protocol are obtained by looking at events with predetermined profiles of benign activity.
