What does this mean for you? Mandiant is a leading Red Team/Penetration Testing company with a highly sophisticated toolkit, called the "Red Team tools." These are digital tools that replicate some of the best hacking tools in the world.

SUNBURST Backdoor: What to look for in your logs now - Interview with an incident responder

Yesterday, FireEye published a report about a global intrusion campaign that utilized a backdoor planted in SolarWinds Orion. Attackers gained access to the download servers of Orion. They managed to infect signed installers downloaded by Orion users who had all reason to believe that the packages are safe and had not been tampered with. With this information out in the world, teams are scrambling to investigate if their environments are affected by this breach.

Triaging Log Management Through SIEMS

While all cybersecurity professionals agree that log management is integral for robust proactive and reactive security, managing the enormous amount of data logs can be a challenge. While you might be tempted to collect all logs generated from your systems, software, network devices, and users, this “fear of missing out” on an important notification ultimately leads to so much noise that your security analysts and threat hunters cannot find the most important information.

Event Log Management for Security and Compliance

Security log management is the process of collecting, storing, and correlating the network data that details all activity in your systems and networks. Every action in an organization’s network generates event data, including records produced by operating systems, applications, devices, and users. The Center for Internet Security (CIS) identifies log management as a basic control for detecting malicious actors and software hiding in networks and on machines.

Detecting Security Vulnerabilities with Alerts

Every day we discover new vulnerabilities in our systems, cracks in the fence the adversaries take advantage of to get into your organization and wreak havoc. Understanding what you have in your environment (e.g., types of devices, systems equipment, etc.) is very important in order to make sure the controls in place are working and more importantly, keeping up with the threat landscape.

Detecting & Preventing Ransomware Through Log Management

As companies responded to the COVID-19 pandemic with remote work, cybercriminals increased their social engineering and ransomware attack methodologies. Ransomware, malicious code that automatically downloads to a user’s device and locks it from further use, has been rampant since the beginning of March 2020. According to a 2020 report by Bitdefender, ransomware attacks increased by seven times when compared year-over-year to 2019.

Whether you are planning to use Graylog for security and threat hunting, IT Operations analysis and reporting, or any other use case, getting your logs into Graylog is essential. The process of log collection is sometimes a daunting task, especially if you are planning to collect massive amounts of data. But if you take a minute to answer some key questions before you begin, you can transform the log collection task from daunting to smooth sailing. Here we go with the questions...

Cyber Security: Understanding the 5 Phases of Intrusion

Here at Graylog, we have recently had an increase in conversations with security teams from leading companies. We want to share our key findings with the Graylog community. The good thing is that cybercriminals use a methodical approach when planning an attack. By understanding their process and knowing your network, you will be better prepared and able to stay one step ahead.

Importance of System Resource Monitoring on Graylog, Elasticsearch, and MongoDB Servers

The first thing we tell Graylog users is, “Monitor your disk space.” The core set of metrics discussed below should always be in acceptable parameters and never grow over extended periods without going back to normal levels. This is why it is critical to monitor metrics that come directly from the hosts running your Graylog infrastructure.
