DNS Security Best Practices for Logging

Your Domain Name System (DNS) infrastructure enables users to connect to web-based resources by translating everyday language into IP addresses. Imagine going into a restaurant, in the age before the internet, only to find that the staff speaks and the menu is written in a different language from yours. Without some shared communication form, you can’t order dinner, and they can’t give you what you want.

Redacting Message Fields for Privacy Purposes

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.

Using IP Lookup for Cybersecurity Monitoring

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.

Why Patching Isn't the Ultimate Goal in Cybersecurity

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.

Building a Security Data Lake Strategy

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.
