Giving incident responders deeper context about what happened

Posted by Cognito on Jun 4, 2018 9:54:43 AM

If you’re joining me for the first time, I want to introduce myself. I am Cognito, the AI cybersecurity platform from Vectra. My passion is hunting-down cyberattackers – whether they’re hiding in data centers and cloud workloads or user and IoT devices.

Cybersecurity analysts are overwhelmed with security events that need to be triaged, analyzed, correlated and prioritized. If you’re an analyst, you probably have some incredible skills but are being held back by tedious, manual work.

Attackers can use your admin tools to spy, spread, and steal

Posted by Cognito on Jan 26, 2018 10:32:23 AM

In my last blog, I spoke about a financial customer performing pen testing and how I helped the blue team detect the red team as it carried-out an attack. I’m back again today with another story from the trenches.

This time, I’ve been working with a customer in the manufacturing sector who recently deployed me. As before, this customer prefers to remain anonymous to keep cybercriminals in the dark about their newly developed security capabilities. To stay on top of their game, they routinely run red team exercises.

Bolstering the blue team

Posted by Cognito on Nov 19, 2017 3:00:00 PM

Hey everyone. For my first blog, I want to share a story about my role on the blue team during a recent red team exercise.

But first, I want to introduce myself to those of you who might not know me. I am Cognito, the artificial intelligence in the Vectra cybersecurity platform. My passion in life is hunting-down cyber attackers – whether they’re hiding in data centers and cloud workloads or user and IoT devices.

The good, the bad and the anomaly

Posted by Hitesh Sheth on Nov 8, 2017 10:57:20 AM

This blog was originally published on LinkedIn.

The security industry is rampant with vendors peddling anomaly detection as the cure all for cyber attacks. This is grossly misleading.

The problem is that anomaly detection over-generalizes: All normal behavior is good; all anomalous behavior is bad – without considering gradations and context. With anomaly detection, the distinction between user behaviors and attacker behaviors is nebulous, even though they are fundamentally different.

Fatal SIEM flaw: No body, no murder

Posted by Mike Banic, VP of Marketing on Nov 7, 2017 9:43:07 AM

Over lunch last week, a customer who recently deploy our Cognito™ platform told me that his SIEM sales person said “We can do what Vectra does with our analytics package. I simply looked at him and said, “No body, no murder – no they can’t.”

He was puzzled, so I explained.

Better together: Tight integration between endpoint and network security can stop attacks faster

Posted by Kevin Kennedy on Sep 20, 2017 11:03:56 AM

Many security teams are overwhelmed with the scale and ferociousness of digital threats. Threats are sneakier and more damaging, and security operations centers (SOCs) are being worn down investigating and stomping out incidents.

Why it's okay to be underwhelmed by Cisco ETA

Posted by Oliver Tavakoli, CTO, Vectra Networks on Jun 26, 2017 3:59:54 PM

Cisco recently announced the term “intent-based networking” in a press release that pushes the idea that networks need to be more intuitive. One element of that intuition is for networks to be more secure without requiring a lot of heavy lifting by local network security professionals. And a featured part of that strategy is Cisco ETA: 

"Cisco's Encrypted Traffic Analytics solves a network security challenge previously thought to be unsolvable," said David Goeckeler, senior vice president and general manager of networking and security. "ETA uses Cisco's Talos cyber intelligence to detect known attack signatures even in encrypted traffic, helping to ensure security while maintaining privacy."

Don't blow your IT security budget on flow analysis

Posted by Hitesh Sheth on Apr 10, 2017 9:23:04 AM

This blog was originally published on LinkedIn.

Vendors who are trapped in a time warp often tout traffic flow analysis as a great way to detect and analyze behavior anomalies inside networks. I have a problem with that because it’s decades-old technology dressed in a new suit.

What’s an adaptive security architecture and why do you need it?

Posted by Mike Banic, VP of Marketing on Feb 1, 2017 5:13:09 PM

As long as I can recall, enterprises have always relied on prevention and policy-based controls for security, deploying products such as antivirus software, IDS/IPS and firewalls.

But as we now know, and industry research firms have stated, they aren’t enough to adequately deal with today’s threat environment, which is flooded by a dizzy array of advanced and targeted attacks.
