Plixer NetFlow Analyzer Puts School's Cyber Threats in Time Out

Bloomington Public Schools Gives Typical Antivirus Software a Failing Grade

SANFORD, ME -- (Marketwire) -- 12/13/12 -- Plixer International, Inc., a leading provider of NetFlow-based network traffic reporting, today announced that Bloomington Public Schools deployed its award-winning Scrutinizer network analyzer, to help protect its network from continued cyber threats that off-the-shelf firewalls and antivirus software failed to detect.

Bloomington Public Schools are comprised of 4,000 students, dispersed across seven different locations. Built to serve three primary groups, students, teachers and faculty, the schools' IT infrastructure is comprised of a central data center with Metro TLS Ethernet links connecting each school via a Cisco backbone as well as the Cisco Unified Computing System (UCS) Server. Finding the best solution to effectively protect the network from cyber threats is a big challenge, as Jason Radford, System Administrator at Bloomington Public Schools explains.

"Our network is like the 'Wild West,' with traffic coming from every direction," said Radford. "This makes it very difficult for our team to effectively monitor and trace network activity."

Over time, the reporting frequency of suspicious PC behavior such as unrelenting pop-up advertisements and extremely slow performance began to increase. After a thorough evaluation, the IT team found that a dangerous virus had manifested itself within the network, and begun reaching out to specific BOTNET Websites as well as sending e-mails to further propagate itself into other PCs and devices.

"Our antivirus software just didn't catch it," continued Radford. "It had already infected more than 100 machines. We turned to Plixer and their Scrutinizer solution for help."

Scrutinizer reports on which hosts, applications, and protocols are consuming network bandwidth and provides custom NetFlow reports to instantly sort data into useful information. Working with Plixer, the Bloomington IT team installed Scrutinizer and created filters for SMTP and specific subnets attempting to hit known BOTNET sites. By using a Scrutinizer saved report as a threat detection algorithm, in less than one hour, the team at Bloomington identified every single infected machine and stopped the virus.

"Scrutinizer permits us to drill-down into any type of traffic -- anywhere on the network -- so we can provide fast answers to potential problems. It has completely changed the way we monitor network traffic," Radford concluded.

Scrutinizer is a one hundred percent web-based tool that provides detailed network utilization reports showing the applications and users generating network traffic. Leveraging the software's domain utilization report, even sites with secured connections that use encrypted traffic can't hide from the insight provided by NetFlow and IPFIX collection and reporting. Scrutinizer is designed to peer deep into bandwidth traffic and enable the network administrator to easily see who is consuming bandwidth, what they are using it for and immediately restore precious bandwidth for work-related needs.

"As computer viruses and malware such as Advanced Persistent Threats (APTs) become more elusive and damaging, companies need to make careful decisions regarding soft security solutions," said Michael Patterson, CEO, Plixer International Inc. "Our Scrutinizer NetFlow Analyzer is capable of amassing a network traffic view that typical firewalls and antivirus tools were not built to provide. We are able to provide a holistic view of the entire enterprise -- regardless of equipment vendor -- to quickly pinpoint the root cause of harmful behavior."

Nowadays, a large number of sensors and devices are connected to the network. Leading-edge IoT technologies integrate various types of sensor data to create a new value for several business decision scenarios. The transparent cloud is a model of a new IoT emergence service platform. Many service providers store and access various types of sensor data in order to create and find out new business values by integrating such data.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
