Round Rock ISD Achieves Pervasive Internal Network Security With Mirage Networks

Austin, TX – June 17, 2004 – Mirage Networks, Inc., the pioneer in security solutions for Interior Defense, today announced that Round Rock Independent School District (ISD), Texas, has deployed the Inverted Firewall throughout its internal network to protect against rapidly propagating threats and network abuses.

Round Rock ISD has a state-of-the-art network that serves more than 35,000 students and 4,000 staff across 43 schools and five administrative facilities. Despite having excellent perimeter security firewalls and intrusion detection systems, Round Rock ISD was unable to stop rapidly propagating threats that were able to bypass these defenses. Since installing the Inverted Firewall, Round Rock ISD has discovered and stopped threats like Sasser and Welchia – without the need to use signatures or deploy agents.

“With our small network IT staff, it is essential that we have an automated solution to stop worms that get past perimeter defenses,” said Dan Scott, Senior Systems Engineer, Round Rock ISD. “With the Mirage Networks solution, instead of 200 or 300 systems to clean up, we’ll only have the initial infection point, which will remain contained until we have the time to remediate that system.”

In addition to containing rapidly propagating threats, Round Rock ISD has used the Inverted Firewall to uncover several network abuses arising from incomplete firewall rules and misconfigured PCs.

“The ROI of the Inverted Firewall was evident immediately,” said Jim Brigham, CTO, Kairos InfoSec Systems. “Within 30 minutes of installation, Round Rock ISD found unwanted reconnaissance – that their industry-leading intrusion detection system missed – and were able to seal an unknown hole in their firewall and shut the intruder out of their network.”

“Educational institutions, because they are trying to create an open learning environment to enable technology-savvy students, often experience more internal threats than external threats,” said Greg Stock, Vice President of Sales and Marketing, Mirage Networks. “With the Inverted Firewall, Round Rock ISD now has pervasive internal network security that can control internal threats and balance its perimeter security investments.”
