Siemens SIMATIC Spectre-NG Variants 3a and 4 (CVE-2018-3639)

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Stor...

Vulnerability Remediation: It’s Not Just Patching

Vulnerability does not equal a patch, as such remediating a detected vulnerability requires deploying the right patches and, in some cases, making the right configuration changes. Using multiple tools to detect, map and deploy the right remediation actions is time consuming and will result in les...
