Common Angular Routing Challenges

When it comes to frameworks, no one is perfect. As we migrate the Logentries application from legacy code to Angular, we’ve encountered a few interesting challenges along the way that we’ve enjoyed investigating and resolving. While specific challenges often depend on your project and migration strategy, the aim of this post is to share our solutions to problems one may encounter when migrating an app to Angular. In particular, I’ll focus on how Angular handles routing and some issues we’ve en

UserInsight Ranks Users by Risky Behavior

UserInsight now ranks risky users through behavioral analytics. UserInsight, the User and Entity Behavior Analytics (UEBA) solution , spots user behavior such as unusual admin activity, authentications to new assets, and new user locations and highlights users that exhibit several such behaviors. The User Risk Ranking augments UserInsight's low-noise incident alerts and enables administrators to g

10 Phishing Countermeasures to Protect Your Organization

The Internet is full of articles for how to tell if an email is phishing but there seems to be a lack of concise checklists how to prepare an organization against phishing attacks , so here you go. Because phishing attacks humans and systems alike, the defense should also cover both aspects. None of the following steps is bullet proof, so layering your defenses is important – and having an incident response plan in case someone does get th

CISOs: Do you have enough locks on your doors?

In a previous blog post , I referenced some research on how people plan for, or rather how they fail to plan for, natural disasters like floods. At the end of the blog post I mentioned that people who have poor mental models about disasters fail to prepare fully. I keep coming back to the idea of mental models because it starts to explain why we have such a gap between security practitioners and senior executives. I asked one CISO

Best Practices for Container Log Analysis: Part 2

This 3-part series explores the challenges presented by containers and the advantages of using an end-to-end container log monitoring solution for complete container environment visibility. When working with containers, setting up a local image repository like Docker’s Registry can enable a team to iterate quickly, easily storing image versions in a central location to be used as needed. Yet as multiple team members update images, start, st

Best Practices for Container Log Analysis: Part 1

This 3-part series explores the challenges presented by containers and the advantages of using an end-to-end container log monitoring solution for complete container environment visibility. As container environments become mainstream, it’s important to consider the most common challenges of migrating a monolithic application into containerized microservices and how to overcome them. While containers introduce new levels of flexibility from

Multiple Insecure Installation and Update Procedures for RStudio (R7-2015-10) (FIXED)

Prior to RStudio version 0.99.473, the RStudio integrated toolset for Windows is installed and updated in an insecure manner. A remote attacker could leverage these flaws to run arbitrary code in the context of the system Administrator by leveraging two particular flaws in the update process, and as the RStudio user via the third update process flaw. This advisory will discuss all three issues. Since reporting these issues, RStudio version 0.99.473 has been released. This version addresses all

Using Reflective DLL Injection to exploit IE Elevation Policies

As you are probably aware, sandbox bypasses are becoming a MUST when exploiting desktop applications such as Internet Explorer. One interesting class of sandbox bypasses abuse IE's Elevation Policies. An example of this type of sandbox bypass is CVE-2015-0016 . The vulnerability has already been analyzed by Henry Li, who published a complete description in this blog entry

The real challenge behind asset inventory

As the IT landscape evolves, and as companies diversify the assets they bring to their networks - including on premise, cloud and personal assets - one of the biggest challenges becomes maintaining an accurate picture of which assets are present on your network. Furthermore, while the accurate picture is the end goal, the real challenge becomes optimizing the means to obtain and maintain that picture current. The traditional discovery paradigm of continuous discovery sweeps of your whole network

What is Elastic Logging?

We’re all familiar with the concept of “Elasticity” – the way cloud infrastructures can automatically react to their required workloads, scaling resources up or down as needed. While elastic environments provide us with much needed flexibility, they have also historically presented challenges when trying to monitor activity from their ephemeral components. Automatically accounting for new nodes can be tricky while scaling up. And when scaling down, data associated with these nodes is potentially

The Absence of Evidence in Breaches

Try this experiment. Go to your favorite search engine and type this: ”no evidence” security compromise (Other variations are also interesting, including adding words like “breach”) There is something about the phrase “no evidence” that troubles me. You may have noticed the same thing. On a regular basis organizations say that there is no evidence of compromise, and no evidence that attackers gained access to user/customer/employee data. They write these phrases to lessen the blow of what is
