Ensuring employees operate securely regardless of location has grown in importance over the last several years as the number of people working remotely has exploded. These workers are most likely operating within a software-defined wide area network (SD-WAN). They use SD-WAN to work with data that is now processed more and more in many different cloud services.

According to the Cloud Security Alliance, the average large enterprise has 946 custom applications deployed. Traditionally, organizations deployed Web Application Firewalls (WAF), which provide visibility and enforce security controls on external traffic that passes through them, at the perimeter to protect these applications against external attacks.

The past three years have been challenging in many ways for the retail industry, and this uncertain reality isn’t going anywhere. The industry continues to face challenges; the cost-of-living and energy crisis, and expected period of economic downturn, are understandably unsettling for all sectors, with retail particularly hard hit in a recessionary period.

Managed NDR is network detection and response (NDR) combined with an outsourced SOC (Security Operations Center) monitoring and response layer. The meaning of “managed” in managed NDR will vary from provider to provider. Some managed NDR services will remediate threats for you, while others will stop at alerting and assisting your internal IT team. Similarly, the capabilities of the “NDR” part of managed NDR will also differ depending on who offers it.

In our new threat briefing report, Forescout’s Vedere Labs provides details on the recent ransomware campaign targeting VMware ESXi virtualization servers, or hypervisors, and analyzes two payloads used in these attacks: variants of the Royal and Clop ransomware. We also present the tactics, techniques and procedures (TTPs) used by attackers in this campaign, discuss mitigation recommendations and list indicators of compromise (IOCs) that can be used for detection or threat hunting.

Firewall optimization (also known as firewall analysis) is the process of analyzing and adjusting the configuration and policy set of a firewall to improve performance and security. This process involves reviewing and corelating log data and device configurations, identifying potential vulnerabilities and weaknesses, and providing recommendations for remediation. Performing these processes is complex, which is why tools like firewall analyzers are useful.
