Many organizations today have strict data privacy regulations that they must comply with. These privacy regulations can often clash with the requirements of security, application and operations teams who need detailed log information. This how to guide walks you through redacting message fields for privacy purposes. At Graylog, many of the organizations who use our tool are logging sensitive data that may contain personally identifiable information, health related data or financial data.

Wherever you live, people can find you using either a street address or a set of latitude and longitude numbers. In the digital world, your website’s domain name or URL is the street address while the IP address is the latitude and longitude. For example, it would be cumbersome to tell people that you live at 35°05′17″N 109°48′23″W, but easy to say a number and street name. IP address data is useful for both protective and detective cybersecurity functions.

A recent analysis by JPMorganChase criticized the CVSS scoring process, finding missing context leads to misleading prioritization. When it comes to cybersecurity, patching vulnerabilities often feels like the Holy Grail. Get those CVEs patched, and you’re safe, right? Well, not exactly. As we know, patching isn’t as straightforward—or as effective—as we’d like to believe.

The high volumes of security data that cloud environments generate leave security teams swimming in data, but many feel like they need a life preserver to improve their incident response capabilities. Enter security data lakes. As the costs associated with data retention become overwhelming, organizations are embracing the idea of security data lakes and data warehouses.

Organizations have grappled with the cost-benefit tradeoff of log management and Security Information and Event Management (SIEM) for decades. Do you capture every log at the risk of overwhelming storage, infrastructure, and license costs, or limit your collection and gamble on what’s truly important? The high costs imposed by traditional vendors have dictated Sophie’s choice, forcing enterprises into a game of compromise that risks the entire organization’s security.

In life, you get a lot of different alerts. Your bank may send emails or texts about normal account activities, like privacy notices, product updates, or account statements. It also sends alerts when someone fraudulently makes a purchase with your credit card. You can ignore most of the normal messages, but you need to pay attention to the fraud alerts. Security is the same way.

Illicit streaming devices have become an unnoticed yet significant threat in many households and corporate environments. These devices, often advertised with wild promises of free access to premium content, have a dark side that many users might not be aware of. They operate much like the “black boxes” of the 1990s, offering access to pay-per-view events and premium channels at suspiciously low costs.

Imagine, for a moment, that your IT environment is the Death Star. You know the rebels will try to rescue Princess Leia. If you’re Darth Vader, you need systems that detect Luke and Chewbacca when they gain unauthorized access and systems that prevent them from accessing the Death Star. As a security analyst, you have varied technologies that detect and prevent malicious actors from gaining unauthorized access to your networks.

2024 was a thrilling year for Graylog Capture The Flag (CTF) events! Across major cybersecurity conferences, Graylog invited participants to test their skills in a range of challenging scenarios designed to simulate real-world cyber threats. From North America to Europe and beyond, we saw cybersecurity professionals and enthusiasts go head-to-head in Graylog CTFs, flexing their skills, deepening their knowledge, and having fun along the way.

Being a security analyst today is hard. You’re constantly trying to protect your organization while feeling like attackers are always a step ahead of you. Every year, you seem to add more security technologies to your stack, yet you still find yourself facing tooling gaps. If only you had the ability to clearly compare different products and their capabilities, you think.
