Continuous packet capture reflects needs of today's networking

This week, bloggers look into ExtraHop continuous packet capture, Oracle's cloud computing goals and the breach at Yahoo.

Drew Conry-Murray, writing in Packet Pushers, reviewed ExtraHop Networks' new network analytics platform, which now includes continuous packet capture. The updated product, ExtraHop 6.0, is intended to better provide actionable intelligence with a physical -- or virtual -- Discover appliance that takes in real-time network traffic data and transforms it into structured data. The Discover appliance can process up to 4 million packets per second.

The product's physical Trace appliance maintains continuous packet capture, with an initial offering of 28 TB of raw capacity -- allowing for approximately six hours of capture per device, Conry-Murray said.

In addition to continuous packet capture, ExtraHop includes data indexing with the Explore appliance and the ability to spot granular transactions, such as a login. According to Conry-Murray, the Discover appliance starts at $10,000, while Trace is priced at $73,500.

Multiple cloud journeys and the modern enterprise

Dan Conde, an analyst with Enterprise Strategy Group Inc., in Milford, Mass., highlighted Oracle's cloud strategy that was revealed at Oracle OpenWorld 2016. At the conference, Dave Donatelli, Oracle's executive vice president for converged infrastructure, spoke of five different paths to the cloud: tailored for business, hardware, software, workload or compliance needs.

Having this many options, however, could prove challenging to companies assessing their cloud strategies, Conde said.

"When we talk of going to the cloud, we often think of some nirvana, where everything is sucked into a public cloud. That may happen in some distant future, but pragmatically speaking, it's not something I envision in the short term," Conde said. He added that many companies may struggle with too many choices and a baffling array of compliance audits, architectures and security protocols for Oracle cloud, or even hybrid offerings from Azure.

To overcome inertia caused by too many options, Conde suggested companies assess what they really need to help them forge the correct cloud strategy.

Takeaways from the Yahoo breach

Avivah Litan, an analyst with Gartner, said she believes the recent breach of 500 million records at Yahoo -- allegedly by state-sponsored hackers -- is "shocking, but not surprising." After all, she said, a majority of Americans have now seen their identities compromised. State-sponsored hackers buy up enormous amounts of data for intelligence uses, and fraudsters steal credentials and data for "credential-stuffing" takeovers of private accounts.

To overcome these challenges, Litan said companies need to cut down on static data, shift to dynamic data and focus on identity proofing. She suggested a four-tier identity-proofing approach for risky transactions, such as logins, profile data changes and money transfers. Litan added that out-of band push notifications, which offer a second layer of security on mobile devices, are a step forward, but are far from a panacea.
