The Intrusion Prevention System (IPS)

The Intrusion Prevention System (IPS)

IPS is an advanced technology to protect your network from malicious attacks. IPS works together with your SPI Firewall, IP Based Access List (IP ACL), Network Address Port Translation (NAPT), and Virtual Private Network (VPN) to achieve the highest amount of securities.

IPS Scenarios

IPS works by providing real-time detection and prevention as an in-line module in a router. The Wireless-N Security Router has hardware-based acceleration for real-time pattern matching for malicious attacks. It actively filters and drops malicious TCP/UDP/ICMP/IGMP packets and can reset TCP connections. This protects your client PCs and servers running various operating systems including Windows, Linux, and Solaris from network worm attacks. However, this system does not prevent viruses attached emails.

The P2P (peer to peer) and IM (instant messaging) control allows the system administrator to prevent network users from using those protocols to communicate with people over the Internet. This helps the administrators to set up company policies on how to use their Internet bandwidth wisely.

The signature file is the heart of the IPS system. It is similar to the Virus definition files on your PC’s Anti-Virus programs. IPS uses this file to match against packets coming in to the Router and performs actions accordingly. As of today, the Wireless-N Router is shipped with signature file version 1.3.8 and with a total of 1101 rules. The rules cover the following categories: DDoS, Buffer Overflow, Access Control, Scan, Trojan Horse, Misc., P2P, IM, Virus, Worm, and Web Attacks.

Customers are encouraged to update their IPS signature file regularly to prevent any new type of attacks on the Internet.
