David Bowie once sang, “ch-ch-ch-changes, turn and face the strange.” While the changes to ISO 27000-series may look strange, they’re primarily a configuration and modernization of the same standard you already know. The standard’s format looks entirely different, but most of your current controls will remain the same.

Welcome to our technical blog, where we’ll be diving into the world of Graylog and how you can secure your Graylog Server with Transport Layer Security (TLS). As an admin or a tech-savvy user, you know the importance of protecting your Graylog Server and the logs it manages from unauthorized access.

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.

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.

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.

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.

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.

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.

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.

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.
