Intrusion Prevention System

Service Description

  • Cloud-Bricks New Generation Firewall integrates the famous SNORT system in order to perform real-time traffic analysis and threat detection.
  • This system is able to detect network attacks and vulnerability exploits. Working in conjunction with the system firewall it can generate alerts or even block attacks based on a preconfigured set of rules. It works in a similar way to Antivirus software for network packets.
  • Cloud-Bricks Web Management Interface also integrates SNORBY, an easy to use Web system useful to browse SNORT generated alerts and monitor your network traffic health.


Snort Rules

The Intrusion Prevention System works based on a set of rules files which contain all the threats definitions. The SNORT system provides 3 different set of rules:

  1. Community rules: Available for free for every one.
  2. Registered user rules: Available for free only for users registered at snort.org
  3. Subscriber rules: High-security rules with the latest updates, available only for paying users.

The Cloud-Bricks system comes with SNORT preconfigured with Community rules only.

If you want to use the "Registered User Rule set", please Sign Up at snort.org, get your oink code and contact our support team.

If you want to protect your system with the most updated threat definition rules and receive support for snort, you may become a snort subscriber.  Our support team will configure your SNORT system with the Subscriber Rule Set.

Configuring your Virtual Machine to use the IPS system

In order to actually make the Intrusion Prevention System to scan your virtual machine network traffic, you will have to include some "IPS Filters" in your Firewall rules.

What to do in case of attack

  • If you see some suspicious activity, alerts or attacks in the Snorby database, you need to identify the IP Address where the attack comes from.
  • The Snorby interface will provide you a link to a web site with an explanation of the rule that was activated.
  • If you are able to confirm this is not a false positive, you may want to block the attacker's IP Address using the Black List Firewall feature.
  • Our support team may be able to help, but keep in mind that if you need specific support for snort, you need to become an snort subscriber.
