Networks

Companies must prioritise a comprehensive and proactive approach to network security. Among the most effective strategies to ensure robust defence mechanisms is rigorous penetration testing. By adopting an “assumed breach” mentality, organisations can better prepare for potential attacks, ensuring they are not merely reacting to threats but actively preventing them.

Over the past twenty years, I have navigated a unique journey through the cybersecurity landscape. My path has taken me from the realms of hacking and academia into the heart of threat intelligence (TI), culminating in my current role. Since I joined Cato in 2021, I’ve been leading security strategy and am proud to share the culmination of Cato’s research efforts in Cyber Threat Research Lab (Cato CTRL), our cyber threat research team.

Microsegmentation represents a transformative approach to enhancing network security within Kubernetes environments. This technique divides networks into smaller, isolated segments, allowing for granular control over traffic flow and significantly bolstering security posture. At its core, microsegmentation leverages Kubernetes network policies to isolate workloads, applications, namespaces, and entire clusters, tailoring security measures to specific organizational needs and compliance requirements.

In the ever-evolving landscape of cybersecurity threats, staying ahead requires more than just detection; it demands comprehensive correlation and analysis for informed decision-making. Understanding the context surrounding an alert is important to effectively mitigate risk. That's why we're thrilled to announce the integration of CrowdStrike Falcon EDR with Investigator, part of Corelight’s Open NDR Platform.

Network migration is a critical undertaking for any organization looking to optimize their network performance, adopt new technologies, or achieve cost savings. However, this process poses numerous challenges that can lead to disruptions and unwarranted risks if not properly managed.

A command injection vulnerability, being tracked as CVE-2024-3400, was recently discovered in the GlobalProtect feature of Palo Alto Networks PAN-OS software. This vulnerability has a CVSS score of 10 (Critical) and is actively being exploited in the wild. It impacts versions PAN-OS 120.2, PAN-OS 11.0 and PAN-OS 11.1. If exploited on vulnerable PAN-OS versions and distinct feature configurations, an unauthenticated attacker could execute arbitrary code with root privileges on the firewall.

Operational technology (OT) and Industrial Control Systems (ICS) are core parts of an engine fueling critical infrastructure in industrialized nations worldwide. Water treatment facilities. Wastewater plants. Electrical transmission and distribution hubs. Nuclear power and manufacturing plants. Energy pipelines.

On Friday, April 12, 2024, Palo Alto Networks PAN-OS was found to have an OS command injection vulnerability (CVE-2024-3400). Due to its severity, CISA added it to its Known Exploited Vulnerabilities Catalog. Shortly after disclosure, a PoC was published.
