Do you need better insight into the overall state of your network security? Take a step back and look through the larger lens of the SIEM solution. Security information and event management (SIEM) is an approach to security management that combines two aspects: Coined in 2005 by Amrit Williams and Mark Nicolett of Gartner, the term SIEM now serves as a synonym for the gathering, analyzing, and presenting network and security information as well as external threat data and vulnerability management.

So, here’s the deal with AntiVirus software these days: It’s mostly playing catch-up with super-fast athletes — the malware guys. Traditional AV software is like old-school detectives who need a picture (or, in this case, a ‘signature’) of the bad guys to know who they’re chasing. The trouble is, these malware creators are quite sneaky — constantly changing their look and creating new disguises faster than AntiVirus can keep up with their photos.

Before diving into our blog post topic, allow me to introduce myself. My name is Joel and I work with the solution engineering team at Graylog. Our primary task is to work with our customers and prospective clients on how to manage and make the most out of Graylog in their respective IT environments. One of our main tasks is to identify the logs sources they should incorporate and the kind of volumes they should anticipate.

How US federal agencies can better meet advanced event logging requirements Recently, the US Government Accountability Office (GAO) released a study tracking US federal agencies’ progress on meeting the requirements set out in OMB M-21-31. Released in 2021, the Office of Management and Budget (OMB)’s M-21-31 memorandum provided guidance and requirements for federal agencies in order to improve centralized visibility into logging data before, during, and after cybersecurity incidents.

If you are an organisation that operates or does business in the European Union (EU), then your team is likely preparing for the NIS2 Directive, an EU-wide legislation on cybersecurity. It provides legal measures to boost the overall level of cybersecurity in the EU and goes into effect on October 17, 2024. However, according to a survey by cybersecurity firm Sailpoint (and a Sumo Logic customer), only 34% of organisations in the UK, France, and Germany are prepared for NIS2.

As we’ve covered before, SIEMs are an expensive tool. The average enterprise-level SIEM deployment costs over £15 million a year, and operating a small, 100 to 1000-seat SIEM will still run up bills of over £10k monthly. SIEMs create spiralling costs that eat security budgets. Without a skilled team operating them, they can also make organisations less secure despite receiving more information about their digital estates. But where do these SIEM costs come from?

On November 14, 2023, FortiGuard published an advisory disclosing that a critical command injection vulnerability (CVE-2023-36553) had been patched in the latest updates for FortiSIEM. The vulnerability was rated with a Common Vulnerability Scoring System (CVSS) score of 9.3, as it can be exploited remotely by an unauthenticated threat actor using crafted API requests to execute unauthorized commands. This vulnerability is caused by improper neutralization of special elements in FortiSIEM report server.

An application’s attack surface is the sum of all the areas of an application which could be attacked by malicious attackers. This includes the application’s APIs, the underlying code, supporting infrastructure, and any other components which could be compromised. The goal for any organization is to reduce the attack surface area by discovering and minimizing potential vulnerabilities.

Security information and event management (SIEM) systems play a pivotal role in cybersecurity: they offer a unified solution for gathering and assessing alerts from a plethora of security tools, network structures, and software applications. Yet, the mere presence of a SIEM isn't a magic bullet. For optimal functionality, SIEM systems must be appropriately set up, governed, and supervised round-the-clock.

As the new year approaches, security professionals and analysts alike are taking a step back to review what has transpired over the past twelve months. At Devo, 2023 was an exciting year full of change and progress. As we look forward to 2024, we want to take some time to reflect on Devo’s year across product enhancements, analyst recognition, partnerships, and community engagement.
