In February 2026, the FBI launched Operation Winter SHIELD (Securing Homeland Infrastructure by Enhancing Layered Defense), a nationwide campaign to empower organizations against evolving cyber threats. Drawing from insights gained in countless investigations—including ransomware, nation-state intrusions, and credential-based attacks—the FBI outlined 10 proven, high-impact defensive actions. These focus on closing common gaps that adversaries exploit time and again.
Implementing these doesn’t require massive overhauls; many are foundational hygiene steps with outsized returns. Here’s a breakdown of each action, what it really means, and practical steps to get started—plus how Black Belt Secure’s services can accelerate and sustain your efforts.
The 10 Key Actions from Operation Winter SHIELD
- Adopt phish-resistant authentication What it means: Most breaches begin with stolen credentials via phishing. Traditional MFA (like SMS or push notifications) can be bypassed; phish-resistant methods (e.g., FIDO2 security keys or passkeys) cryptographically prove identity without shareable secrets, drastically reducing initial access success. Practical steps: Prioritize admins/executives first; deploy hardware keys or device-bound passkeys for VPN, email, and critical apps; require number-matching for authenticator apps; disable SMS MFA and legacy protocols. How We Help: Our vCISO service helps design and roadmap MFA upgrades, while MSSP monitors for anomalous logins.
- Implement a risk-based vulnerability management program What it means: Attackers routinely exploit known, unpatched flaws because organizations lack prioritized processes. A risk-based approach scores vulnerabilities by exploitability, asset criticality, and business impact for faster remediation. Practical steps: Build/maintain an asset inventory with owners and criticality ratings; scan internally/authentically; set SLAs (e.g., critical vulns patched in days); document exceptions with compensating controls and deadlines. How We Help: Our MSSP includes continuous vulnerability scanning and prioritization; Jutsu adds threat-hunting to validate patches.
- Track and retire end-of-life (EOL) technology on a defined schedule What it means: Unsupported systems (no security updates) are prime targets for exploitation. Tracking EOL prevents “forgotten” assets from becoming backdoors. Practical steps: Forecast EOL 12+ months ahead; review quarterly with owners/procurement; isolate or replace EOL devices; apply temporary mitigations with hard sunset dates if delays occur. How We Help: vCISO conducts asset lifecycle audits; MSSP monitors legacy systems for anomalies.
- Manage third-party risk What it means: Vendors with access can be the weakest link—attackers chain-compromise supply chains. Extending security governance to partners prevents bypass attacks. Practical steps: Inventory third parties with access/data roles; enforce least-privilege, strong auth, and monitoring; include breach notification/encryption in contracts; revoke access promptly on termination and audit data handling. How We Help: Our vCISO develops third-party risk programs; MSSP extends visibility into vendor connections.
- Protect security logs and preserve them for an appropriate time What it means: Attackers delete logs to cover tracks; preserved, centralized logs enable detection, forensic response, and attribution. Practical steps: Centralize key logs (auth, endpoint, network, cloud) in a SIEM/immutable storage; retain 12+ months; sync clocks; test log completeness quarterly via user/server activity reviews. How We Help: MSSP provides SIEM management and log monitoring; Jutsu uses preserved logs for incident hunting/response.
- Maintain offline immutable backups and test restoration What it means: Ransomware targets backups first; offline/immutable copies ensure recovery without paying, while testing confirms viability. Practical steps: Follow 3-2-1 rule (3 copies, 2 media types, 1 offline/immutable); secure backup admin access; define RTO/RPO; test restores regularly and measure times. How We Help: Jutsu includes backup validation in incident response; MSSP advises on immutable storage setups.
- Identify, inventory, and protect internet-facing systems and services What it means: Exposed assets (unpatched RDP, etc.) offer easy entry. Inventory and hardening minimize the public attack surface. Practical steps: List all internet-reachable assets with owners; remove unnecessary exposure; use VPN/gateways for remote access; scan public IPs regularly for shadow IT. How We Help: MSSP performs external attack surface management and monitoring.
- Strengthen email authentication and malicious content protections What it means: Email is a top initial vector; weak DMARC/SPF/DKIM allows spoofing, and poor filtering lets malware through. Practical steps: Enforce DMARC (progress to reject), SPF, DKIM; quarantine risky attachments/macros; enable link protection and block auto-forwarding. How We Help: MSSP integrates advanced email security and phishing simulation training.
- Reduce administrator privileges What it means: Excessive admin rights allow rapid lateral movement/escalation post-compromise. Least-privilege limits blast radius. Practical steps: Minimize admin accounts/groups; use just-in-time/elevated access from secure devices; separate admin/user accounts; remove local admin rights on endpoints; monitor privilege changes. How We Help: vCISO designs privilege access management strategies; MSSP enforces and alerts on violations.
- Exercise your incident response plan with all stakeholders What it means: Plans on paper fail in reality; regular exercises build muscle memory, clarify roles, and speed containment/recovery. Practical steps: Maintain a concise playbook; run quarterly tabletop exercises (60 mins) with tech, legal, comms, leadership; include FBI/local contacts for coordination. How We Help: Jutsu leads tabletop simulations and full IR exercises; vCISO refines plans.
These 10 actions form a practical blueprint for resilience—many align with CISA’s Cybersecurity Performance Goals and FBI alerts on threats like ransomware and state actors. Operation Winter SHIELD emphasizes that layered, consistent implementation of these measures significantly reduces risk.
At Black Belt Secure, we don’t just advise—we implement and manage these defenses through our MSSP (continuous monitoring and response), Jutsu (advanced threat hunting and incident response), and vCISO (strategic advisory and program building) services. Whether you’re starting from basics or maturing your posture, our team can help prioritize and execute these steps tailored to your environment, fully aligned with Operation Winter SHIELD guidance.
