Today's Huge Networks Need Agile Security Tools to Ferret Out Malware
NEWS ANALYSIS: With networks getting larger faster and facing ever more threats, many network products at the GEN15 conference emphasize new approaches to security.DALLAS—Over the past year it's safe to say that both metro and global Ethernet are exploding. According to numbers released to the press at the Metro Ethernet Foundation's GEN15 conference here, wide area versions of Ethernet are showing 100 percent growth year over year. Most of the growth is in networks delivering bandwidth of 1 gigabit or greater. In fact, the MEF has already certified six vendors for 100 Gigabit Ethernet, and networks with that bandwidth are already going into place. But having all that bandwidth adds to problems in other areas, one of which is security. It's not that such high speeds change the security landscape, exactly; it's that security needs to become more sophisticated to keep up. Finding security appliances that will work at 100G bps requires groundbreaking hardware. And that's only the start. With the growth of these massive networks, the complexity changes. A typical metro Ethernet may have to work with different edge vendors. The logical network may have to work across varying Ethernet topographies and different network hardware. Furthermore, it may be connected to a wider global network with access in places that are more risky than in the United States.
To top it all off, as these networks have grown, different parts will have different management software and, in many cases, different managers. So the question becomes how to keep the network secure from end to end. As you probably suspect by now, there's also no single solution.
