An In-Depth Look at the NSA's Zero-Trust Guidance to Guard Against Network Adversities In a bid to bolster network security and hinder adversaries' lateral movement, the National Security Agency (NSA) is recommending organizations to adopt the zero-trust framework principles. At its core, the zero-trust security architecture puts stringent controls on accessing network resources — whether they're within or beyond the physical boundary. This results not only in limiting the breach impact but also in keeping the network protected. The Zero-Trust Framework Unlike the traditional IT security model, where everyone and everything within the network perimeter is trusted, the zero-trust architecture operates on the premise that a threat may already be lurking inside. Hence, it denies unrestricted access to the network, keeping potential risks at bay. A key aspect of enhancing the zero-trust maturity involves addressing several elements, known as pillars, which threat acto...

Introduction When it comes to cybersecurity, compliance may not be the most eye-catching topic, yet it is undoubtedly significant. In the current digital age, security teams play a vital role in Governance, Risk, and Compliance (GRC) concerns thereby warranting their due recognition in any security organization's objectives and priorities. Notably, various compliance standards and frameworks have recently adopted requirements that echo security best practices rather than mere checkboxes, making the case for PCI DSS 4.0, the newest credit card standard, all the stronger. Let’s delve deeper into its facets and what security professionals can glean from the changes. The Noteworthiness of PCI DSS 4.0 The Payment Card Industry Security Standards Council (PCISSC), comprising main credit card industry players like Visa, Mastercard, American Express, Discover, JCB International, and UnionPay, are responsible for setting up and administering the credit card standard. As per this ...
