Today we are releasing Graylog v2.5.1 to fix a few bugs. Many thanks to our community for reporting issues and contributing fixes!

SIEM and log management provide security to your organization; these tools allow your security analysts to track events such as potential and successful breaches of your system and react accordingly. Usually, it doesn’t matter how you ensure your organizational safety-as long as you do.

Logging is a data collection method that stores pieces of information about the events that take place in a computer system. There are different kinds of log files based on the kind of information they contain, the events that trigger log creation, and several other factors. This post focuses on log files created by the three main operating systems--Windows, Mac, and Linux, and on the main differences in the ways to access and read log files for each OS.

To stay competitive, companies who want to run an agile business need log analysis to navigate the complex world of Big Data in search of actionable insight. However, scouring through the apparently boundless data lakes to find meaningful info means treading troubled waters when appropriate tools are not employed. Best case scenario, data amounts to terabytes (hence the name “Big Data”), if not petabytes.

So, you’ve done your homework, you’ve clearly defined business requirements, and you’ve decided to implement a SIEM solution into your organization. However, before you set out on this adventure there are a quite a few questions to consider.

We are happy to announce that Graylog v2.5 is now available. This release includes several new features, including support for Elasticsearch 6.x, along with numerous bug fixes.

Investing in a log analysis tool provides many benefits: it saves time needed to detect and troubleshoot a problem, reduces churn by providing a better user experience, and improves system security. There is a wide scope of use cases for log analysis - from tackling security and performance issues head-on to enhancing the quality of your services. What are some of the most common use cases for log file analysis?

In the digital era, we need to track and record all of our data at all times. From a user logging into the dashboard to database queries, JavaScript errors, and website traffic, everything that matters is recorded in a log. You name it, and with due probability, you already have time-stamped documentation of all the events saved somewhere in the form of a log.

With so many choices available to us today, choosing log management software that’s just right for us has never been simpler. That is, if you know exactly what it is you are looking for. But for many users, the sheer amount of computer programs that perform the same tasks, and seem so similar(sometimes almost identical) to each other, can quickly become off-putting and confusing.

Most organizations use their SIEM solution to automate repetitive security tasks, saving analysts time. But the reality is your system could be doing—and saving—so much more by blocking the obvious threat actors attempting to connect with your network, systems, and assets.
