The Spectre vulnerability that has haunted hardware and software makers since 2018 continues to defy efforts to bury it. . On Thursday, Eduardo (sirdarckcat) Vela Nava, from Google's product security response team, disclosed a Spectre-related flaw in version 6.2 of the Linux kernel. The bug, designated medium severity, was initially reported to cloud service providers – those most likely to be affected – on December 31, 2022, and was patched in Linux on February 27, 2023 . "The kernel failed to protect applications that attempted to protect against Spectre v2, leaving them open to attack from other processes running on the same physical core in another hyperthread," the vulnerability disclosure explains. The consequence of that attack is potential information exposure (e.g., leaked private keys) through this pernicous problem. . A flaw in the Linux kernel version 6.2 related to Spectre could lead to possible data exposure for cloud service vendors, raising concerns about security vulnerabilities..

The cloud is fairly new territory for many organizations and, consequently, it’s an area where mistakes are made stemming from confusion around the role cloud service providers play in security, and how companies should work with them.. "Organizations looking to host their data in cloud service providers have the best intentions in mind, and the clients I speak with are looking at security as being a key motivator," says Mark Judd, research analyst at Gartner's Research Analyst Lab.. When evaluating cloud providers, it's essential to explore key questions that enhance your data management and security strategies for better protection and compliance.

As a information security executive, what are your concerns related to disaster recovery and business continuity of your cloud applications? In Organizing sensitive data in the cloud, I mention configuration information for each cloud service layer (software, platform, infrastructure, and security) needs to be kept in a directory. I have a significant concern though. . Today, there are hundreds to thousands of permutations for vendors product configurations that may be deployed in the cloud. The sheer number of features supported for each product are mind-numbing. This makes disaster recovery and business continuity a nightmare. Only financial services companies invest the money necessary to replicate the applications and core infrastructure to ensure that a disaster can be effectively handled. This is too expensive for many small and medium sized corporations. What is the key to disaster recovery success? The cloud provider needs to minimize the number of product vendors and the corresponding features they deploy. This reduces the number of permutations that must be tested. Hence, a cloud user can have assurance that the cloud provider's web solution will work for them. I'll examine a cloud application scenario. How should the directory be designed to assist in deploying a cloud based application? A cloud application is supported by a web server that interfaces with a database which runs on an operating system contained within a virtual machine. The virtual machine acquires the network and storage resources it needs to support the application. The flavors of virtualized networking products and storage components also need templates associated with them. The link for this article located at CSO Online is no longer available. . Organizations must adopt key strategies for cloud disaster recovery, such as multi-region deployments, automated backups, and rigorous testing for resilience and continuity.
