Intrusion Prevention- the best protective shield for the internet users

Have you ever wondered why all of a sudden your computer slows down and does not accept any particular command or sometimes you receive any weird mails or messages? This is all because of the interference of any unauthenticated elements into your computer or your internet network.

Every day many people come across many security threats that hinder their normal online activities and cause lots of destruction and losses. To overcome this situation our computer and networks are fortified with the help of the intrusion prevention systems.

Intrusion Detection and Prevention Systems (IDPS) are the network security appliances that monitor the network or the activities of the computer. The supreme functions of an IDPS are to identify the malicious activities, log or extract information about the activities, attempt to block or stop them and report the activities.

The best part of the network security, the Intrusion Prevention Systems are so designed to protect your vital information from unauthorized access, damage or disruption. Intrusion prevention technology is considered as an extension of the intrusion detection (IDS) technology, but is actually another way of access control like the firewall security supports.

For the best internet security, you must know how Intrusion Prevention System works. Being the part of the network security systems like firewalls, antivirus programs, Intrusion Detection Systems tries to identify attacks as it occurs. Unlike firewalls that stop services by blocking certain port numbers but do little to evaluate traffic by using the allowed port numbers, IDS can evaluate traffic that passes through these open ports but cannot stop it. The Intrusion detection system proactively blocks the attacks.

rnIf you will look into the distinction between the IDS and IPS, you will find that Intrusion Detection Technology is out of the band technology whereas the Intrusion Prevention System performs in-line on the network. The IPS monitors the network very much like the IDS but when an event (the detection) occurs, it takes action on the prescribed rules.

Intrusion Prevention System can be achieved through three main estimations:

1- Crafting the systems without any vulnerability.

2- Can act perfectly by taking the perfect remediation steps remove the threats and patch them.

3- Detecting the attack and exploit attempts and block them before serious damage is done.

IPS functions on the In-line mode i.e. the sensor is placed directly in the network traffic path by inspecting all traffics at wire speed. In-line mode enables the sensor to run in a protection/prevention mode, where packet inspection is performed in real time to drop the malicious packets. This enables it to actually prevent the attack reaching its target.

Therefore with the help of the Intrusion Detection System, your cyber security issues can be easily handled like the breaches of the security policy by the computer user.
