In computing, an audit log is a record of an event. An event is any significant action that impacts the hardware or software of a computer – anything from a mouse click to a program error. Besides documenting which resources were accessed and what for, an audit file system will also include the source and destination addresses, the timestamp, and the user ID information.

With the rapid expansion in both scale and variety of technologies in modern business systems, there comes a need to further secure those technologies to prevent nefarious actors from causing havoc. The expanding data landscape creates a much larger attack surface for bad actors to exploit, and as a result leaves many organizations at risk from theft, fraud or other undesirable behavior.

Event correlation tools are a fundamental instrument in your toolbox to detect threats from all sources across your organization in real time. A wise use of the right event correlation techniques through log management and analysis is the cornerstone of any reliable security information and event management (SIEM) strategy – a strategy that focuses on prevention rather than reaction.

Vulnerability management (VM) is a challenging task. Of the three pillars of people, process, and technology, it is the latter that we have the most control over and that can make the greatest impact. We recognize that technology alone is not sufficient and must be accompanied by strong processes and skilled personnel. However, the right technology can greatly facilitate and improve the effectiveness of our vulnerability management efforts.

The Sumo Logic Threat Labs team previously outlined the risks associated with unprotected cloud credentials found on Windows endpoints. This article builds on that work by providing detection and hunting guidance in the context of endpoints that run the Linux operating system. Although workloads that support business functionality are increasingly moving to the cloud, these workloads are often managed through an endpoint that is often found on premises.

The decision to buy a Security Information and Event Management (SIEM) product or outsource to a Managed Detection and Response (MDR) service depends on a number of factors, including the size of your organization, the complexity of your IT infrastructure, and your overall security needs.

Free and open access is one of the core principles upon which Elastic was originally built and continues to operate. Our products are free to use, and much of our code is accessible in public source code repositories. In recent years, this commitment to transparency and availability has extended to our security offerings.

ManageEngine Log360 was featured in the GigaOm Radar report on Automated Security Operations Management (ASOM), published in October 2022 and written by Logan Andrew Green. The research firm’s report includes an in-depth study of the solutions offered by some of the major vendors in the market and highlights Log360 as a Challenger in the ASOM sector. Log360 is a unified SIEM solution from ManageEngine with integrated DLP and CASB capabilities.

Authentication, at its core, is the act of verifying credentials. In the case of human beings, it’s as simple as answering the question, “Who are you, and how do I know for sure it’s you?” Authentication is something we’re constantly engaging with in everyday life.

At the global level, there is enough demand for security information and event management services to generate more than $4 billion every single year. Over the next several years, experts, predict that this industry will continue to grow at a rate of more than 5% each year.

Proactive event notification is one of the most valuable components of centralized log management and SIEM. It allows us to identify problems, misconfigurations, and potential security risks at an early stage. One of the ways we can improve event notification within Graylog is through the use of Lookup Tables.

Our SOC Performance Report found that it takes an average of seven months to fill open SOC positions, and 55% of those doing the hiring are struggling to find qualified staff. As a result, SOC resources are strained, putting the team at risk for fatigue and burnout, which can cause them to miss critical alerts. Research has shown this is a widespread issue, too, as most SOCs waste an average of 10,000 hours annually validating unreliable and incorrect alerts.

Cyber attacks are becoming more frequent, targeted, and complex. When it comes to sophisticated attacks, one of the most commonly seen tactics is Lateral Movement. During lateral movement, many attackers try impersonating a legitimate user by abusing admin tools (e.g., SMB, SAMBA, FTP, WMI, WinRM, and PowerShell Remoting) to move laterally from system to system in search of sensitive information.

If your company is like many others, it probably invested heavily in the Microsoft ecosystem. Microsoft has been around since the 1980s, focusing primarily on business technologies. It has a reputation for compatibility which gives you more purchasing options across devices and accessories. Unfortunately, this reach across corporate IT environments means that malicious actors target everything associated with Microsoft.
