Context makes network security policy smarter, but not easier
Traditional approaches to network security are no longer sufficient to combat today's advanced threats. Attacks now target users and applications, and experts say an approach called context-aware security is essential to the defense. That's because a context-based model dynamically adapts network security policy based on how an activity correlates to known patterns of behavior, identity, data classification and device profiles. But it's an approach that's best for enterprises with mature security programs, as discussed in this edition of Network Evolution. Network security teams that use context-based strategies without having done the upfront architecture work are set up for failure.
Also in this issue, we find network engineers easing into software-defined networking (SDN) with a hybrid model that gradually or partially introduces SDN into a legacy networking environment. And finally, find out why several networking pros say learning a programming language is now vital.
Features in this issue
Context-aware security has the potential to make network security a lot smarter. But it also requires legwork many IT shops aren't equipped to handle.
Enterprises aren't ready to revamp entire networks for SDN, but it's not a zero-sum game. A hybrid SDN strategy introduces it gradually or partially.
Networking pros don't need to become code monkeys, but a little network programming can go a long way toward advancing their careers.
Network downtime is often a necessary evil for network upgrades, but in the world of 24/7 broadcast media, maintenance windows are hard to come by.
Columns in this issue
Today's network security threats demand a context-based approach, but without a good grasp of security basics, context won't do you much good.
