6 Tips for Living a Healthy Digital Life and Avoiding Credential Theft This Holiday Season

Posted by Eran Cohen on Nov 29, 2018 7:51:00 AM

Most of us still dream practical, down to earth, old fashioned dreams. And I’d place a bet that not many people, if any, dream about their credentials being stolen.  Almost all of my memories from the last 15 years or so are stored digitally. The majority of my day to day activity is managed online. My online persona is almost identical to my physical one. I imagine that  many of you are in the same situation.

Zero Trust: Why Implementation Doesn’t Have to Mean Painful Surgery On Your Network – Pt. 2

Posted by Eran Cohen on Oct 24, 2018 7:50:17 AM

Across the conference circuit and the general cybersecurity community this year, Zero Trust – a term originally coined in 2010 – has been perhaps the industry’s hottest buzzword. Move over, blockchain and machine learning. In my previous blog, I outlined what Zero Trust means and what lessons the framework offers for the security community. To recap the challenges of Zero Trust: organizations face hurdles around securing legacy applications/network resources and tools and protocols; regulatory headwinds given that the framework can theoretically conflict with global legislation, including GDPR; and the looming reality that the typical large global enterprise lacks the organization-wide visibility and control necessary for implementation. Here, I’ll outline a framework for a true Zero Trust model that adheres to industry best practices while specifically avoiding the potential for an over-engineered network overhaul, wasted IT budget, and potentially costly organizational disruption.

Hostile by definition: Thoughts on Zero Trust Security – and its pitfalls. Part 1

Posted by Eran Cohen on Oct 4, 2018 12:03:15 PM

(Note: see part two of our Zero Trust blog posts here)

It’s a common question after a major breach: did you do everything you could have to protect your network? Most of the time the answer is...probably not. Often, we live in a false sense of security. We know it, and most of us are OK with it. But let's talk about what’s practical and what steps can be taken to help you get to a better sense of security.

Transitioning applications to the cloud doesn’t have to mean sacrificing security, visibility or control

Posted by Eran Cohen on Aug 30, 2018 9:42:30 AM

A CISO recently told us that despite having an impressive array of cybersecurity solutions during their transition to the cloud, nothing was tying it all together from a threat standpoint. From her perspective, all the security tools at their disposal were great individually, but lacked visibility across all accounts and all platforms. Further, they didn’t have the ability to identify and respond to threats, as well as user access requests, in a consistent manner. It actually made the job harder and less effective. This vulnerable patchwork approach of disparate vendor solutions is all too common.

Shopping for a Cyber Security Product? 7 Tips to Help You Get What You Need.

Posted by Eran Cohen on Aug 13, 2018 12:56:59 PM

It’s increasingly difficult and more complex to be an effective buyer of security products today. Messaging and content overlaps are everywhere, cloud platforms claim to do what endpoint solutions do, and all the while products are constantly pivoting in the middle of operation - often changing their identity and main purpose. At the same time, enterprise and personal priorities change, vendor awards are presented to whoever pays more, analysts are not always aligned, and the list goes on.

How to Use Identity, Behavior and Risk to Prevent Compromised Credentials

Posted by Eran Cohen on Jan 25, 2018 10:00:00 AM

Identity, Behavior and Risk. Identity, Behavior and Risk. Almost like a mantra. Think about it for few seconds. Identity, Behavior and Risk are the 3 main pieces of evidence that security personnel would like to deeply understand so they can protect their organization and users from credential compromise

Getting the Most out of a Security Product POC

Posted by Eran Cohen on Jan 21, 2018 3:00:00 PM

Vendors, especially in the over crowded security space, often must help buyers justify their investment. But what happens when there isn’t a real problem during the test period? This can make it difficult to properly assess. Some security vendors will simulate problems, others may sponsor penetration tests, or they may provide a list of tests and tools, and so on. In the highly competitive End Point market (aka AntiVirus) they will use any tool they may have in the box.

QakBot, Stop Playing with my Active Directory!

Posted by Eran Cohen on Jun 23, 2017 9:39:32 AM

Really, it’s not just me saying that Active Directory is the crown jewel. It's actually them, the hackers, that de facto target the active directory in almost every advanced attack. They look for domain credentials and administrative accounts, they practice domain reconnaissance, privilege elevation, targeted attacks against the domain controller and more. Their motivation is similar to terror. For example: produce widespread fear, obtain recognition and attention of media, steal money, damage facilities and functionalities. This is why it was not surprising to learn about the QakBot Trojan causing a mess.

The Insider Threat Denial Syndrome

Posted by Eran Cohen on May 18, 2017 12:01:22 PM

I believe there is a “denial syndrome” that exists in cyber security. I’m not referring to the “It won’t happen to me” concept, I’m pointing to a deeper and more dangerous belief. In psychology, denial happens when we are uncomfortable with the facts of reality and instead of dealing with it we reject it, insisting it is not correct.
