Last week I had the opportunity to speak with several CISOs about what they are doing to deal with cyberattacks, breaches and internal threats. A consistent theme I heard is that detection only solutions aren't enough. They need more practical approaches to rapidly respond to anomalous behavior and they need to reduce burden on analysts. Working smarter not harder. This is one of the great benefits of real-time threat prevention based on identity, behavior and risk. It can removes work from analyst via adaptive response and automated resolution of false positives. One customer recently told me that within just a couple months, automated response has helped them improve their efficiency by 30-40%. That’s a lot of time that can focused on more critical security tasks.
Service Accounts can represent tremendous security risk for enterprises. And many of our customers struggle with how to best identify, control and protect these accounts. Let’s take a closer look at what service accounts are and what organizations can do to protect service accounts from attackers and insiders.
In the past year I have seen a big shift in the conversations I've had with CISOs. What used to be all about how to keep the bad guys out, is now about, how do I manage the threats that are already on the inside. Their security strategies are broadening to address Insider Threats and they are implementing, or looking to implement, technologies and solutions to help them better understand what’s really going on inside their organization and to find ways to reduce their risk.
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.
It was recently published that Shadow Brokers, the group behind the Equation Group leak, are selling a new set of tools that have the ability to tamper with Windows event logs. What stood out to me is the inefficiency of security solutions that rely solely on logs for detecting threats. Implementing a security analytics or a UEBA product that relies on logs for detection of advanced cyber threats has advantages, but it is also risky.
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.
In our Part 1 Series we talked about User and Entity Behavior Analytics (UEBA) and its benefits for better detecting possible breaches and insider threats through user and entity behavior and risk scoring. Now let’s talk about the differences between traditional UEBA vs the newer UEBA solution, the Behavioral Firewall, which integrates adaptive responses to prevent threats.
Enterprises define security policies that match their business objectives. By setting security policy rules, an organization can better enable the business to achieve its goals while protecting them from advanced threats. They work reasonably well, even allowing for the well publicized breaches and insider threats. Without policies or a set of tools in place for such eventualities, it will be very difficult for the business to operate effectively when under attack.
I believe detection and prevention are the most chewed-over words in the security market. In the last 20 years, I have seen the term virus evolve to worm and horse (trojan). Then it left the living creature world and moved to the “Bond” world by becoming spyware, malware, ransomware and even getting recognized by names, such as Zeus, Cryptolocker and more.
And yet the basic terms of detection and prevention have remained steady. No matter the triggers, no matter the technology or the company. Sometimes you’ll hear detection and prevention used together and sometimes separately depending on the solution’s capabilities. What changes with these terms lies underneath as the threats to organizations continue to proliferate.
In the past few days we all learned of the latest advanced cyber espionage spyware, ProjectSauron. An in-depth analysis was published by Kaspersky Lab, and found it to be one of the most advanced cyber-warfare malware ever made. The malware was named ProjectSauron after reference to the evil dark lord of Lord of the Rings was found embedded in the code.
