Sigma Rules Guide for ArcSight

1,830

Introduction to Sigma Sigma, created by Florian Roth and Thomas Patzke, is an open source project to create a generic signature format for SIEM systems. The common analogy is that Sigma is the log file equivalent of what Snort is to IDS and what YARA is for file based malware detection. However, unlike Snort and […]

Integrating QRadar with VirusTotal

Hello. In the last article we considered creating rules, and today I want to describe the method that will help SIEM administrators respond to possible security incidents faster. When working with information security incidents in QRadar it is extremely important to increase operators’ and analysts’ operation speed in SOC. Usage of built-in tools provides ample […]

In the previous article I have demonstrated how to create a simple dashboard that monitors accessibility of sources in Splunk. Today I want to demonstrate you how to make any table in the dashboard more obvious and convenient. Let’s look at my last article and continue to improve the functionality of the table that I […]

A very common task for all ArcSight content developers is cleaning active lists on a scheduled basis or on-demand automatically. In the previous post I have described how to clear Active Lists on scheduled basis using trends:¬†https://socprime.com/en/blog/active-lists-in-arcsight-automatic-clearing-part-1/ Today I will show you another two ways how this can be achieved. Automatic clearing of Active Lists […]

In the previous article, we have examined using depends panel for creating convenient visualizations in dashboards. If you missed it, follow the link: https://socprime.com/blog/using-depends-panels-in-splunk-for-creating-convenient-drilldowns/ Many people who begin to study Splunk have questions about monitoring the availability of incoming data: when the last time the data came from a particular source, when the data ceased […]

Creating Rules in IBM QRadar

Last week, I wrote about how to update your IBM QRadar. But the correct operation of any SIEM is not only updating the build, or collection and storage of events from various data sources. The primary task of SIEM is to identify security incidents. The vendor provides preconfigured detection rules for IBM QRadar, but most […]

In the previous article, we have examined simple integration with external web resources using drilldowns. If you missed it, follow the link:¬†https://socprime.com/en/blog/simple-virus-total-integration-with-splunk-dashboards/ Today we will get acquainted with one more interesting variant of drilldowns in Splunk: using depends panels. Depends panels in Splunk: an interesting way to use drilldowns in dashboards   Very often there […]

Updating IBM QRadar

616

The efficient SIEM operation directly depends on fixing detected vulnerabilities and issues in its functioning. The primary method for this is updating the system to the latest version. Updates can include fixing security issues, releasing new functionality, improving system performance, patches, and so on. In my recent article, we reviewed how to create backups in […]

Almost all of the ArcSight beginners face a situation when there are a high incoming EPS from the log sources, especially when it is critical to License limits or causes performance issues. To reduce incoming EPS, ArcSight has two native methods for event processing: Event Aggregation and Filtration. In this article, I will try to […]

In the previous article, we examined Additional Data fields and how to use them. But what if events do not have needed/required/necessary information even in Additional Data fields? You may always face the situation when events in ArcSight don’t contain all needed information for Analysts. E.g., user ID instead of username, host ID instead of […]
