Networking blogs: Big data security trifecta, distributed firewalls

In this week's blog roundup, read about the three areas big data security needs to encompass, and get expert insight on distributed firewalls.

The big data security analytics 'trifecta'

Conventional wisdom states that status quo security isn't adequate against today's growing cyberthreats, so we need more sophisticated analytics to combat threats in the face of big data. But what exactly is the "big data" behind big data security analytics? Enterprise Strategy Group senior principal analyst Jon Oltsik contends that big data security analytics haven't yet reached their true potential.

Read now to learn the three key areas Oltsik believes big data security analytics need to encompass in order to work effectively in today's security landscape.

In this post, Brad Hedlund delves into the distributed firewall, where traffic steering is removed from the process of implementing security policy.
