Discover how to navigate risk compliance during the kernel patching process, which is critical to protecting sensitive data and maintaining compliance with IT risk frameworks like NIST, CIS Controls, ISO 27001, and PCI DSS. This blog post delves deep into understanding these frameworks and provides a step-by-step guide to effectively manage risk compliance when patching, from risk assessment and patch prioritization to testing and continuous monitoring. In this blog post, you’ll also learn how to master the delicate balance of ensuring system security while adhering to industry standards with these actionable insights.
Intel CPUs are under threat from the “Downfall” vulnerability (GDS), which might expose stale data, especially affecting processors using Intel AVX2 and AVX-512. This flaw allows potential attackers to retrieve data from certain registers, and in extreme cases, extract cryptographic keys. Dive into this post to understand the risks, performance impacts, and immediate steps you can take to safeguard your systems, backed by insights from Red Hat and Intel’s own advisory.
Boost your CentOS 7’s security by effectively harnessing SELinux, a potent kernel security module often underutilized due to misconceptions. This blog post unveils how SELinux, with its granular control, can act as a proactive shield against threats, even during vulnerable periods between security flaw discoveries and patch releases. Jump into this post to gain an understanding of SELinux’s practical applications, ensure fewer weak links in your system, and maximize your Linux-based infrastructure’s defense capabilities.
While patching software addresses vulnerabilities and is crucial for meeting compliance standards, simply patching for compliance isn’t enough these days. The timeframes set by compliance standards may leave systems exposed to rapid exploits, with zero-day vulnerabilities posing particular challenges. Check out this post to learn about the gap between patching and compliance and why a comprehensive, timely patching strategy is vital for genuine security against evolving threats.
