Versa UEBA incorporates GraphML to generate insights and detect anomalies in user relationship graphs. Anomaly and behavior detections are just the first step. We then need to quickly pivot into building the forensics to inform response and remediation. This can involve determining the origination point of a malicious activity or an attack and building the scope and scale of a potential breach.
CVEs: CVE-2024-3400; Summary Recently Palo Alto Networks announced a critical vulnerability in their PAN-OS software used in their GlobalProtect VPN Gateway, which is a feature in the PAN-OS Firewall. The discovery and public disclosure of the vulnerability and fixes timeline is currently as follows: Volexity first discovered the PAN-OS attack on April 10, 2024 at one of its network security monitoring (NSM) customers, and on April 11, 2024 subsequently learnt that another NSM customer was compromised by the same threat actor. Palo Alto Networks was then notified by Volexity that a zero-day vulnerability in its GlobalProtect Gateway was under active…
In the rapidly evolving landscape of cyber threats, data protection has become a priority concern. Traditional security models are proving inadequate in the face of sophisticated attacks, leading organizations to seek out more dynamic and robust approaches to securing their data. The integration of Secure Access Service Edge (SASE) and Zero Trust architectures offers a promising approach to modern cybersecurity challenges. In this blog, we delve into how Versa Networks merges SASE and Zero Trust to ensure the protection of data in today’s landscape.
Cloud security is mission critical especially in an environment where cyber threats have evolved in frequency and sophistication like never before making the need for highly efficient and robust cloud firewall solutions is undeniable. CyberRatings.org (CRO) is a cyber assessment firm focused on providing independent, objective ratings of security product efficacy based on real-world testing. They just finished a rigorous evaluation of eleven vendors in the Cloud Network Firewall space, including the Versa Next Generation Firewall (NGFW) for cloud deployments. This detailed analysis tested Cloud Firewall performance for key capabilities across: Routing and access control TLS/SSL functionality Stability and reliability…

CVE Description CVSSv3 Severity CVE-2024- 1709 (CWE-288) Authentication Bypass Using Alternate Path or Channel 10.0 Critical CVE-2024- 1708 (CWE-22) Improper Limitation of a Pathname to…
Summary This security bulletin focuses on understanding the sophisticated exploitation of critical n-day and zero-day vulnerabilities in VPN and other network devices by state-sponsored threat actors, reinforcing the urgency for organizations to prioritize patching vulnerabilities in appliances known to be targeted. The recent exploitation of the critical FortiOS vulnerability followed a disclosure by CISA and other federal agencies revealing that China-linked threat group Volt Typhoon has been known to exploit network appliances from several vendors including Fortinet. Fortinet released a blog post to coincide with the U.S. agencies’ advisory, which pointed to “the need for organizations to have a robust…
Securing the over three billion IoT devices globally connected to corporate systems via mobile networks presents a formidable and growing challenge for organizations worldwide. Driven by the adoption of newer IoT-specific cell technologies like LTE-M, NB-IoT, and LTE-Cat 1, along with a boom in 5G module shipments as older 2G and 3G modules are phased out, the number of cell-connected IoT devices is growing 27 percent a year, taking market share from Wi-Fi and Bluetooth connections. My recent collaboration with the network and security team of one of our industrial customers provided a front-row seat to the complexities of safeguarding…
Introduction: Interest in SASE has exploded with CIOs and CISOs alike. The promise of dramatic cost reductions, security improvements and improved agility delivered by a converged networking (SD-WAN) and security (SSE) infrastructure is compelling. However, today’s SASE solutions are commonly delivered on a shared global infrastructure of PoPs provisioned by a handful of technology vendors. This approach doesn’t always meet everyone’s requirements. A “shared” SASE approach is generally good enough for many companies, delivering unified networking and security capabilities with fast time to market and cloud/SaaS economics. But because these shared services lack any ability to control and manage service…
CVEs: CVE-2023-46805, CVE-2024-21887, CVE-2024-21888, CVE-2024-21893 Summary Recently, Ivanti Connect Secure appliances have faced active exploitation through a series of linked vulnerabilities of high or critical severity. On January 10, 2024, Ivanti disclosed two new vulnerabilities in its Ivanti Connect Secure and Ivanti Policy Secure gateways: CVE-2023-46805 (high severity authentication bypass vulnerability) and CVE-2024-21887 (critical severity command injection vulnerability).
To 100G and Beyond: The Next Frontier for SASE In the ever-evolving landscape of enterprise networking and security, a significant transformation is underway. Siloed, point product infrastructures are giving way to a Secure Access Service Edge (SASE) approach, driven by the rapid adoption of cloud technologies, the increased reliance on collaboration tools, and the emergence of hybrid work models.
