Secure Your Network from the Inside
Most network security issues now come from the inside rather than through the Firewalls. This is mainly due to :-
• Spyware and Malware downloaded from Social Networking Sites
• Peer to Peer and Skype users
• .exe files downloaded at home
• Laptops that are used in multiple locations bring known applications and traffic inside the network.
Many of these issues will look at first glance to be normal Microsoft and Web traffic, hence technology needs to be able to look at the content to determine the exact nature of the threat. LanGuardian uses Deep Packet Analysis and Network Behavioural Analysis to spot traffic that looks normal but contains threats.
If malicious traffic does get into the network, they is a need to spot it as early as possible before is uses bandwidth and ties down server resources. ConSentry Network Access Control (link to follow) enables you block wanted or unnecessary traffic as source rather than letting it converse the network before being rejected. This also uses the Active Directory policies that you have on your servers to control traffic flow rather than creating more VLAN groups.
Much of today’s network security is reliant on solid Layer 2 & 3 configuration which is getting more difficult to manage. There are specific ratings and features in NetCordia (link to follow) designed to check how secure the configuration of your network hardware is and generate reports on the issues.
