ScreenDoor Brief
ScreenDoor is a simple-to-use, easy-to-implement network appliance that leverages patented core technology to solve the problems associated with conventional Internet access management products. Connect the ScreenDoor appliance to the Ethernet network you wish to manage, install the ScreenDoor Administrator software on any workstation that can see that network, and you're prepared to easily and efficiently control access without the drawbacks of conventional products.
Full Network Performance. ScreenDoor avoids performance issues created by needing to funnel all traffic through a single point in the network. ScreenDoor passively monitors all activities until called to action when it efficiently terminates offending connections with a single network-level command.
High Availability. Because it is a passive device, it is impossible for ScreenDoor to interrupt internal Internet-bound network traffic in the event the appliance fails for some reason. In that case, simple and cost effective redundant implementation options can insure that you'll always be protected.
Stealthy Operation. Due to its patented core technology, ScreenDoor is virtually impossible to identify, locate, circumvent, or dismantle, even for the most sophisticated hacker. This means ScreenDoor will not become a target for mischievous or malicious users on your network.
Effective Internal Protection. Network security begins with firewalls but shouldn't end there. ScreenDoor also protects against unauthorized access to sensitive internal servers, network services, or protocols within your internal network, thus dramatically reducing the chance of security incidents.
Easy Implementation and Configuration. ScreenDoor integrates seamlessly in any TCP/IP network regardless of operating systems, hardware, or applications and requires no physical machine-by-machine setup.
PacketHound Brief
Most companies have installed firewalls and other technologies to defend their networks from illegitimate use and external attacks by outsiders. But what about the problems introduced by insiders, those with legitimate reasons for using the network? PacketHound specifically targets one of the most significant of these insider problems: the bandwidth, liability, productivity, and security issues introduced through the use of new Internet technologies such as Napster, Aimster, and RealMedia.
Bandwidth. Napster, Aimster, and other distributed peer to peer (P2P) technologies use tremendous amounts of bandwidth. The University of Missouri found that from 10 a.m. until 2 p.m. weekdays, their bandwidth usage was not too heavy, but after 2 p.m., when students began to return from class and fire up Napster , use became so heavy (bandwidth was often as much as 50% Napster) that many more mission-critical academic tasks could not be accomplished.
Liability. The Recording Industry Association of America recently won their lawsuit against Napster for hosting copyrighted materials. If your users are sharing copyrighted material on your network, your organization could be held responsible for their activities.
Productivity. If a number of users on a network are using file-sharing and streaming technologies, the effect on the organization's bandwidth can be staggering, limiting the productivity of everyone in the organization as the entire network slows down. Additionally, users who are downloading music, video, and picture files are less likely to be productive than those who are not.
Security. According to Information Security Magazine, Peer-to-peer (P2P) technologies such as Napster, Gnutella, and their dozens of copycats introduce significant security issues:
1. Users can share any files they have read access to, including all files on network if permissions have not been adequate secured. Using Wrapster to disguise zip files as MP3 files, users can trade your source code and confidential files through Napster and other P2P technologies.
2. Gnutella users were recently struck by the W32.Gnuman.worm the first virus transmitted through P2P technologies. Because P2P clients come from a variety of unknown open-source distributions, files downloaded from Napster, Gnutella, and others may contain back doors, trojan horses, and viruses.
Using PacketHound, you can prevent and eliminate bandwidth, liability, and security risks on your network even if your network has already been compromised by the use of file-sharing and streaming applications. If you do not already have a problem PacketHound gives you the opportunity to protect your network from future exposure to these applications. |
