AMD Acknowledges Newly Disclosed Flaws In Its Processors — Patches Coming Soon

AMD Acknowledges Newly Disclosed Flaws In Its Processors — Patches Coming Soon

Mar 21, 2018
AMD has finally acknowledged 13 critical vulnerabilities, and exploitable backdoors in its Ryzen and EPYC processors disclosed earlier this month by Israel-based CTS Labs and promised to roll out firmware patches for millions of affected devices 'in the coming weeks.' According to CTS-Labs researchers, critical vulnerabilities ( RyzenFall, MasterKey, Fallout, and Chimera ) that affect AMD's Platform Security Processor (PSP) could allow attackers to access sensitive data, install persistent malware inside the chip, and gain full access to the compromised systems. Although exploiting AMD vulnerabilities require admin access, it could help attackers defeat important security features like Windows Credential Guard, TPMs, and virtualization that are responsible for preventing access to the sensitive data from even an admin or root account. In a press release published by AMD on Tuesday, the company downplays the threat by saying that, "any attacker gaining unauthorised ad

13 Critical Flaws Discovered in AMD Ryzen and EPYC Processors

Mar 13, 2018
Security researchers claimed to have discovered 13 critical Spectre/Meltdown -like vulnerabilities throughout AMD's Ryzen and EPYC lines of processors that could allow attackers to access sensitive data, install persistent malware inside the chip, and gain full access to the compromised systems. All these vulnerabilities reside in the secure part of the AMD's Zen architecture processors and chipsets—typically where device stores sensitive information such as passwords and encryption keys and makes sure nothing malicious is running when you start your PC. The alleged vulnerabilities are categorized into four classes—RYZENFALL, FALLOUT, CHIMERA, and MASTERKEY—and threaten wide-range of servers, workstations, and laptops running vulnerable AMD Ryzen, Ryzen Pro, Ryzen Mobile or EPYC processors. Discovered by a team of researchers at Israel-based CTS-Labs, newly disclosed  unpatched vulnerabilities defeat AMD's Secure Encrypted Virtualization (SEV) technology and could
SaaS Compliance through the NIST Cybersecurity Framework

SaaS Compliance through the NIST Cybersecurity Framework

Feb 20, 2024Cybersecurity Framework / SaaS Security
The US National Institute of Standards and Technology (NIST) cybersecurity framework is one of the world's most important guidelines for securing networks. It can be applied to any number of applications, including SaaS.  One of the challenges facing those tasked with securing SaaS applications is the different settings found in each application. It makes it difficult to develop a configuration policy that will apply to an HR app that manages employees, a marketing app that manages content, and an R&D app that manages software versions, all while aligning with NIST compliance standards.  However, there are several settings that can be applied to nearly every app in the SaaS stack. In this article, we'll explore some universal configurations, explain why they are important, and guide you in setting them in a way that improves your SaaS apps' security posture.  Start with Admins Role-based access control (RBAC) is a key to NIST adherence and should be applied to every SaaS a
