How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl
Mar 21, 2024SaaS Security / Endpoint Security
In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must shorte

PixieFail UEFI Flaws Expose Millions of Computers to RCE, DoS, and Data Theft
Jan 18, 2024 Firmware Security / Vulnerability
Multiple security vulnerabilities have been disclosed in the TCP/IP network protocol stack of an open-source reference implementation of the Unified Extensible Firmware Interface ( UEFI ) specification used widely in modern computers. Collectively dubbed  PixieFail  by Quarkslab, the  nine issues  reside in the TianoCore EFI Development Kit II ( EDK II ) and could be exploited to achieve remote code execution, denial-of-service (DoS), DNS cache poisoning, and leakage of sensitive information. UEFI firmware – which is responsible for  booting the operating system  – from AMI, Intel, Insyde, and Phoenix Technologies are impacted by the shortcomings. EDK II incorporates its own TCP/IP stack called  NetworkPkg  to enable network functionalities available during the initial Preboot eXecution Environment ( PXE , pronounced "pixie") stage, which allows for management tasks in the absence of a running operating system. In other words, it is a client-server interface to  boot a
