MADISON, Wis. (Aug. 13, 2010) — Businesses must be two steps ahead of hackers when it comes to managing the barrier between their network and the world. In an upcoming free webinar, TDS Telecommunications Corp. (TDS®) is offering tips and information to help businesses outpace hackers.

On Aug. 25 at 2 p.m. EST, TDS will host the third in a four-part series of webinars. Guest speaker Johannes Ullrich, Ph.D., chief technology officer of the SANS Internet Storm Center, will discuss:

* How business networks become compromised (and ways to keep them safe).

* Threats and ways to control traffic between a business’s network and the Internet.

* Managing network traffic to fit a business’s preferences.

* Thwarting hacker attacks.

“By now, most companies realize the benefit of securing their computers with anti-virus software,” says Scott Meier, product manager of managed security services at TDS. “Hackers know this and have moved on to more advanced attacks against networks. Businesses may think it’s too complicated or expensive to defend their network, however, it’s now a required step to protect your business and your data.”
