Intel Admits It Won't Be Possible to Fix Spectre (V2) Flaw in Some Processors

Apr 04, 2018
As speculated by the researcher who disclosed Meltdown and Spectre flaws in Intel processors, some of the Intel processors will not receive patches for the Spectre (variant 2) side-channel analysis attack In a recent microcode revision guidance ( PDF ), Intel admits that it would not be possible to address the Spectre design flaw in its specific old CPUs, because it requires changes to the processor architecture to mitigate the issue fully. The chip-maker has marked "Stopped" to the production status for a total 9 product families—Bloomfield, Clarksfield, Gulftown, Harpertown Xeon, Jasper Forest, Penryn, SoFIA 3GR, Wolfdale, and Yorkfield. These vulnerable chip families—which are mostly old that went on sale between 2007 and 2011—will no longer receive microcode updates, leaving more than 230 Intel processor models vulnerable to hackers that powers millions of computers and mobile devices. According to the revised guidance, "after a comprehensive investigatio...
Intel Releases New Spectre Patch Update for Skylake Processors

Intel Releases New Spectre Patch Update for Skylake Processors

Feb 08, 2018
After leaving million of devices at risk of hacking and then rolling out broken patches, Intel has now released a new batch of security patches only for its Skylake processors to address one of the Spectre vulnerabilities (Variant 2). For those unaware, Spectre ( Variant 1, Variant 2 ) and Meltdown ( Variant 3 ) are security flaws disclosed by researchers earlier last month in processors from Intel, ARM, and AMD, leaving nearly every PC, server, and mobile phone on the planet vulnerable to data theft. Shortly after the researchers disclosed the Spectre and Meltdown exploits , Intel started releasing microcode patches for its systems running Broadwell, Haswell, Skylake, Kaby Lake, and Coffee Lake processors. However, later the chip maker rollbacked the firmware updates and had to tell users to stop using an earlier update due to users complaining of frequent reboots and other unpredictable system behavior after installing patches. Although it should be a bit quicker, Intel i...
7 PAM Best Practices to Secure Hybrid and Multi-Cloud Environments

7 PAM Best Practices to Secure Hybrid and Multi-Cloud Environments

Dec 04, 2024Risk Management / Zero Trust
Are you using the cloud or thinking about transitioning? Undoubtedly, multi-cloud and hybrid environments offer numerous benefits for organizations. However, the cloud's flexibility, scalability, and efficiency come with significant risk — an expanded attack surface. The decentralization that comes with utilizing multi-cloud environments can also lead to limited visibility into user activity and poor access management.  Privileged accounts with access to your critical systems and sensitive data are among the most vulnerable elements in cloud setups. When mismanaged, these accounts open the doors to unauthorized access, potential malicious activity, and data breaches. That's why strong privileged access management (PAM) is indispensable. PAM plays an essential role in addressing the security challenges of complex infrastructures by enforcing strict access controls and managing the life cycle of privileged accounts. By employing PAM in hybrid and cloud environments, you're not...
