IPS / IDS

IPS / IDS

As the usage of internet is increasing day by day, network security is becoming critical part. The network has to be protected by unauthorized intruders. An intrusion prevention system performs this task efficiently. An intrusion prevention system is a network security device that monitors network and system activities for malicious or unwanted behavior and can react, in real-time, to block or prevent those activities. An IPS is typically designed to operate completely invisible on network and it takes the actions which include dropping packets, resetting connections, generating alerts, and even quarantining intruders on a network. IPS has the ability to look at layer 7 protocols like HTTP, FTP, and SMTP which provides greater awareness and protection of the network.

We provide you advanced IPS solutions that protect your network from:

1. Stopping threats including worms, Trojans, viruses, denial of service, reconnaissance, and exploits against application and operations system vulnerabilities before they enter your network.

2. Network-Based IPS Solutions.

Our expert team can design an IPS solutions as per your business needs to protect your network in real time.

Need for Intrusion Prevention Systems

Firewalls, antivirus software as well as patches are sufficient protection for IT systems - this view is extremely unrealistic. Accordingly, IT managers now consider these classic protection mechanisms often insufficient. More and more business processes are running via the internet and the security requirements have amplified considerably.

Increasing amount of critical data is accepted from outside - such as emails, web services or VPN data from partners as well as from employees. So for that some control over firewalls and open ports is required to check the actual package content.

Present Network Security Risks

Important data that is send from legitimate ports may not be stopped by the firewalls. Plus firewall is of no use against attacks from within like viruses that are introduced unconsciously or deliberately by media and mobile devices.

Independent patching system does not give total protection. Local IT managers require 30 to 60 days for bringing a single patch on the system with 110 bases.

The increasing speed with which fresh issues appear on internet; firewalls, anti virus programs and regular patch cycles may no longer cover them. There is an increase in frequent and faster attacks due to loopholes in operating system and in programs which integrate different solutions. The system requires a temporary shield that can give enough time to generate a patch for the systems. One solution to block the dangers before they go into a corporate network is intrusion prevention system (IPS).

How IPS Functions?

Intrusion prevention system is a solution that aims to prevent an attack. An intrusion prevention system sits on the LAN and verifies the data packets that the firewall has classified as legal network traffic. For this purpose hardware plus software agents are utilized to administer the network traffic and then decide whether to pass data packets or not.

Kinds of Intrusion Prevention Systems

Two varieties of intrusion prevention systems are used. One is network intrusion prevention system and the other one is host intrusion prevention system.

a) Network Intrusion Prevention Systems

Network intrusion prevention systems usually sit on components within the network. They examine entire traffic between given segments to protect them. If the classified data packet is harmless then it is forwarded to Layer 2 or Layer 3. If the data packets are identified as dangerous, the intrusion prevention system rejects it. Via single point of monitoring all the succeeding sections are protected.

b) Host Intrusion Prevention Systems

A host intrusion prevention system is a program that is loaded on to servers, workstations and notebooks. The host intrusion prevention system prevents the host from running the harmful programs on host and examines the traffic that originates from the individual system. It functions in 2 directions: If the doubtful traffic is coming from the host then it is blocked directly at the network interface. This is significant, since there are chances that an employee on his desktop views the infected attachment from an email.
