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
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.
Full disclosure: I wasn’t physically at BlackHat 2017. But my colleagues who attended told me about the keynote by Alex Stamos, CSO at Facebook.
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.
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.
True Positives. It’s a topic of great interest to me. Security Operations can spend a lot of time dealing with separating out the truly non-malicious events. There is an easier way. But, before we go further, let’s align and calibrate on the terminology of True/False Positives/Negatives. Some of these terms have varying levels of agreement. It reminds me of VLAN-- you can have 5 people in the room and there will be 6 different definitions for it. To make sure we are on the same page, let's start with basic definitions accompanied with real life examples.
Password leaks from public breaches help us learn how people think, allow us to identify patterns and build dictionaries of passwords. As password cracking methods evolve, Upper characters, Lower characters, Special characters and Digits (ULSD) recommendations and password complexity mean less.
Big Data is a revolution that in my opinion is equivalent to other epiphany moments such as when humanity (i.e. Galileo) identified that the sun isn’t moving. It's our planet that moves around it. Science and discovery have changed the way people perceive the world.
Think about this statement: “Half of the people you know are below average.” In simple terms, it means that statistically most of the people you know are considered to have average intelligence, or just below or above the line. Does this mean they are dangerous? Does it mean you should reconsider your friendship? Let’s not jump to conclusions just yet.
Noise. Noise. Noise. Our world is noisy. It's all over the place. Visual noise, physical noise. And then there is the noise which bothers analysts in the security industry. I am referring to the security signal to noise ratio that is only growing and growing because of the evolving techniques, various data sources and the unknown threats that we all want to catch (or is it afraid to miss?). In fact, the elephant has left the room and is now visible to all.
