This week’s security landscape is marked by multiple zero-day vulnerabilities, sophisticated identity attacks, and the growing abuse of AI in cyber operations. CISOs should focus on rapid patching, monitoring for credential theft, and preparing for advanced threat scenarios. Below are the top items requiring executive attention, followed by a concise action checklist. Top Items CISOs Should Care About (Priority) Apple Fixes Exploited Zero-Day Affecting iOS, macOS, and Apple Devices What happened: Apple released urgent patches for a zero-day vulnerability actively exploited in the wild, impacting iOS, macOS, and other Apple devices. Why it matters: Exploited zero-days in widely used devices pose significant threat and regulatory risk. What to verify internally: Confirm all Apple devices are updated to the latest OS versions. Review device management policies for timely patch deployment. Assess exposure of high-value users and executives. ...

Cybersecurity governance does not stop at your network perimeter. Modern enterprises rely on a complex ecosystem of vendors, cloud providers, SaaS platforms, integrators, and partners. Each dependency introduces risk—often outside the direct control of the CISO. GV.SC (Supply Chain Risk Management) exists to ensure those risks are governed with the same rigor as internal cybersecurity controls. In NIST CSF 2.0, GV.SC formalizes how organizations identify, assess, manage, and oversee cybersecurity risk originating from suppliers and third parties . What GV.SC Is Designed to Address GV.SC focuses on governing risks that arise from: Third-party service providers Software supply chains and dependencies Cloud and managed service providers Strategic business partners Mergers, acquisitions, and outsourcing While technical controls may reduce exposure, governance ensures that supply chain risk is understood, accepted, mitigated, or avoided at the leadership level . Why Supply Chain Risk Is a ...

Staying ahead of emerging threats is essential for enterprise resilience. This week brings a mix of critical vulnerabilities, advanced ransomware, and sophisticated nation-state activity. CISOs should prioritize patching, review detection capabilities, and prepare executive responses to evolving risks. Below are the top items requiring immediate attention, notable developments, and a concise action checklist. Top Items CISOs Should Care About (Priority) Microsoft Patches 59 Vulnerabilities Including Six Actively Exploited Zero-Days What happened: Microsoft released patches for 59 vulnerabilities, including six zero-days currently being exploited in the wild. Why it matters: Unpatched systems are at high risk of compromise and regulatory scrutiny. What to verify internally: All Microsoft systems are patched promptly, especially endpoints and servers. Vulnerability management processes are up to date and effective. Critical assets are prioritiz...

In the previous post on GV.PO – Policies, Processes, and Procedures , we focused on how organizations define expectations for cybersecurity. But governance does not stop at documentation. Policies without oversight are aspirational at best—and risky at worst. This is where GV.OV (Oversight) comes in. Under NIST CSF 2.0 , GV.OV ensures that cybersecurity governance is actively monitored, challenged, and reinforced by leadership. It transforms governance from a static control set into a living management discipline. What GV.OV Really Means in Practice GV.OV focuses on accountability. It ensures that: Cybersecurity decisions are made at the right level Risk is understood, accepted, or rejected explicitly Leadership visibility extends beyond dashboards and heat maps In short: someone is clearly responsible , and oversight mechanisms exist to confirm cybersecurity is being executed as intended. This category ties cybersecurity directly to enterprise governance , not just IT operations. C...

After decades leading cybersecurity programs in large, global organizations, I’ve learned that governance only matters when it shows up in daily decisions . Policies that live in binders, processes that no one follows, and procedures that exist only for audits do not reduce risk—they create the illusion of control. The GV.PO category in NIST CSF 2.0 exists to close that gap. Where Organizational Context defines what matters , Risk Management Strategy defines how decisions are made , and Roles and Responsibilities define who decides , GV.PO defines how governance is operationalized across the enterprise . What GV.PO Is GV.PO – Policies, Processes, and Procedures ensures that cybersecurity governance is formalized, actionable, and consistently executed across the organization. GV.PO addresses questions leaders often overlook: Do our policies reflect how we actually operate? Are processes designed for the business or for auditors? Can teams execute security procedures under pressure? A...

After more than twenty years leading cybersecurity programs in global enterprises, I’ve seen sophisticated security architectures fail for one simple reason: no one was truly accountable . Technology does not fail in isolation—organizations do. GV.RR exists to eliminate the ambiguity that undermines even the most mature security programs by clearly defining who is responsible, who is accountable, and who has authority to make decisions about cybersecurity risk. In NIST CSF 2.0, GV.RR formalizes something CISOs have long known: governance without clear ownership is performative. What GV.RR Is GV.RR – Roles, Responsibilities, and Authorities focuses on ensuring that cybersecurity responsibilities are clearly defined, assigned, communicated, and enforced across the organization. GV.RR answers leadership-level questions such as: Who owns cyber risk at the enterprise level? Who has authority to accept or transfer risk? How do responsibilities differ between IT, security, legal, complian...
