Threat Hunting vs Incident Response for Cyber Resilience

Protecting data and protecting business continuity are both similar and different. In a data driven world, your mission as a security analyst is to prevent threat actors from gaining unauthorized access to sensitive data and systems. Simultaneously, you also need to investigate incidents rapidly, ensuring that critical services experience as little downtime as possible.

Threat Detection and Response: 5 Log Management Best Practices

In a world where attackers can move fast, security teams need to move faster. According to SANS research from 2022, adversaries can perform intrusion actions within a five-hour window. While analysts need the Millennium Falcon of security technologies that enable threat detection and response in under twelve parsecs, increasingly complex IT environments make the 1-10-60 Framework feel unachievable.

Detecting the 3CX Supply Chain Attack with Graylog and Sigma Rules

According to reporting by several cybersecurity publications the 3CX Desktop Application has been exploited in a supply chain attack. The 3CX client is a popular VOIP and messaging application used by over 600,000 companies. From the article on Bleeping computer This supply chain attack, dubbed ‘SmoothOperator’ by SentinelOne, starts when the MSI installer is downloaded from 3CX’s website or an update is pushed to an already installed desktop application.

The Ultimate Guide to Sigma Rules

In cybersecurity as in sports, teamwork makes the dream work. In a world where security analysts can feel constantly bombarded by threat actors, banding together to share information and strategies is increasingly important. Over the last few years, security operations center (SOC) analysts started sharing open source Sigma rules to create and share detections that help them level the playing field.

CLM and Turkish KVKK Personal Data Protection Law

Data’s role in business processes continues to evolve. Today, organizations collect, store, process, and transmit more personal data than ever before, and legislative bodies respond by updating privacy laws. In 2016, Turkey passed the first iteration of its Personal Data Protection Law number 6698 (PDPL), which also established the Kişisel Verileri Koruma Kurumu (KVKK), the country’s data protection authority.

Centralized Log Management for NIS2 Directive Compliance

As digital transformation expands the threat landscape, compliance mandates adapt to meet new challenges. In 2020, the European Commission announced its decision to accelerate its revision of the Directive on Security of Network and Information Systems (NIS2). When carrying out its impact assessment, the Commission realized that it needed to update the NIS Directive in response to new risks.

Audit Log: Feature Guide for Security and Compliance

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.

The importance of event correlation techniques in SIEM

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.

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.

Risk Based Alerts Using Lookup Tables

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.
