Full Report
According to this year’s Microsoft Digital Defense Report, government agencies and services were the sector most impacted by cyber threats in 2026, accounting for 27% of observed activity, up from 17% in 2025.

Analysis Summary
# Best Practices: Interconnected Cyber Risk & AI Resilience
## Overview
These practices address the escalating threat landscape where government agencies are primary targets for nation-state and criminal actors. They focus on shifting from isolated incident response to a holistic, ecosystem-wide resilience strategy necessitated by the speed of AI-driven attacks and the interconnected nature of modern infrastructure.
## Key Recommendations
### Immediate Actions
1. **Strengthen Identity Access Management (IAM):** Prioritize securing valid accounts, as phishing and compromised identities remain the top entry points (23% of intrusions).
2. **Establish Rapid Response Channels:** Define clear roles and responsibilities for communication between agencies and private sector partners to counter the sub-24-hour weaponization window of new vulnerabilities.
3. **Audit Publicly Exposed Applications:** Conduct a sweep of all Internet-facing assets to close common entry points used by both nation-state and criminal actors.
### Short-term Improvements (1-3 months)
1. **Map Critical Service Dependencies:** Identify the specific identities, systems, suppliers, and infrastructure that support essential government functions.
2. **Implement Multi-Directional Information Sharing:** Move beyond consuming threat intelligence; establish mechanisms to share local signals (like account compromises) with central agencies or partners to reveal coordinated campaigns.
3. **Adopt Secure-by-Design AI Principles:** Evaluate current AI implementations for resilience, focusing on data integrity, model security, and supplier transparency.
### Long-term Strategy (3+ months)
1. **Institutionalize Scenario-Based Exercises:** Conduct regular, cross-sector tabletop simulations (e.g., following the ARC program model) to practice coordination under pressure.
2. **Develop Shared-Service Security Models:** Centralize security and response capabilities to support local governments and smaller public institutions that lack the resources to build independent defenses.
3. **Build an "Interconnected Risk" Framework:** Shift planning from "isolated compromise" to "cascading failure" models, accounting for how a breach in one supplier or partner can cross sectoral boundaries.
## Implementation Guidance
### For Small Organizations (Local Government/Public Services)
- **Leverage Shared Services:** Instead of building a custom SOC, utilize state-level or national shared security platforms.
- **Focus on Hygiene:** Prioritize MFA and patch management for the projected 72,000+ annual CVEs.
### For Medium Organizations
- **Supplier Risk Audits:** Conduct formal reviews of third-party service providers and technology partners to understand their security posture.
- **Internal Exercises:** Run departmental drills to ensure personnel know how to escalate an incident when an entry point (like phishing) is detected.
### For Large Enterprises (Federal/National Agencies)
- **Global Collaboration:** Establish formal partnerships with international peers and the private sector to track nation-state activity.
- **AI Governance:** Create a dedicated AI security agenda integrated into the broader critical infrastructure protection plan.
## Configuration Examples
*While the article focuses on strategic imperatives, the following technical focuses are implied:*
- **Endpoint Detection and Response (EDR):** Configure to alert on "Living off the Land" techniques—where attackers use legitimate administrative tools (e.g., PowerShell, WMI) to blend in.
- **Conditional Access Policies:** Implement "Zero Trust" configurations that require re-authentication when a user switches between internal agency applications and third-party supplier portals.
## Compliance Alignment
- **NIST Cybersecurity Framework (CSF) 2.0:** Aligns with the "Govern" and "Recover" functions.
- **ISO/IEC 27001:** Relevant to supply chain security and incident management.
- **CISA Cross-Sector Cybersecurity Performance Goals (CPGs):** Aligns with information sharing and incident response planning.
## Common Pitfalls to Avoid
- **The "Silo" Trap:** Treating AI security as a separate technical issue rather than an ecosystem-wide resilience challenge.
- **Underestimating Dwell Time:** Assuming that a lack of alerts means no intrusion; attackers are increasingly mimicking legitimate user behavior.
- **Narrow Impact Assessment:** Evaluating an incident only by its starting point (e.g., one stolen laptop) rather than its potential to spread to partners or critical infrastructure.
