CISA's latest innovation bundles two powerful, **open-source resources** into one coherent strategy: a web-based application called **Playbook-NG (Cyber Eviction Strategies Playbook Next Generation)** and a robust database of **post-compromise countermeasures** named **COUN7ER**. Together, these tools promise to transform how organizations respond to and recover from active **cyberattacks**.

Here’s how it works: You simply feed Playbook-NG with details of adversary activities – known **TTPs (Tactics, Techniques, and Procedures)** or descriptions of the breach. In return, the application instantly provides recommended **response actions**, creating a custom roadmap for remediation. These plans are fully exportable and editable, giving you complete control.

But Playbook-NG goes further. It’s not just for active incidents. You can also use it to generate realistic scenarios for **tabletop exercise (TTX)** drills, honing your team’s skills before a real crisis hits. Imagine training with battle-tested templates describing specific collections of TTPs in a campaign or event, quickly customizing them to your organization’s unique environment. This agile guidance follows a "write once, share many" model, ensuring your team always has the latest, most effective **defensive strategies** at their fingertips.

COUN7ER: The Definitive Database of Digital Defenses Behind Playbook-NG's powerful recommendations lies **COUN7ER**, a meticulously curated collection of **post-compromise countermeasures** and mitigations. This isn't just a list; it's a comprehensive knowledge base designed to give your team the upper hand. COUN7ER’s entries are cross-referenced with leading **cybersecurity frameworks** – including MITRE’s ATT&CK, D3FEND, and Common Weakness Enumeration (CWE) – ensuring alignment with industry best practices. Each of its more than 100 fully developed entries provides granular detail on: * Intended outcome * Preparation steps * Potential risks * Related countermeasures * Clear guidance * References for further research This means every recommended action is backed by robust intelligence. CISA itself regularly reviews and updates the COUN7ER database, ensuring it remains dynamic and relevant, incorporating the latest incident observations and **threat intelligence**. Each countermeasure undergoes a rigorous review process, guaranteeing accuracy and consistency. It’s like having a team of elite **threat detection** specialists constantly refining your digital shield. Beyond Eviction: Building a Zero Trust Future CISA's commitment to enhancing **network security** doesn't stop at incident response. This week also saw the release of new guidance as part of its ongoing **Journey to Zero Trust** series. The latest installment, "Microsegmentation in Zero Trust, Part One," dives deep into introducing and planning for **microsegmentation** within a **zero trust** architecture. This crucial document defines core concepts, details a phased approach to implementing microsegmentation, and provides vital planning considerations alongside practical examples. It's an essential resource for organizations looking to build more resilient, inherently secure environments, further reinforcing their **digital defenses** against evolving threats.
