In response to recent malicious cyber incidents in Ukraine—including the defacement of government websites and the presence of potentially destructive malware on Ukrainian systems—CISA has published “CISA Insights: “Implement Cybersecurity Measures Now to Protect Against Potential Critical Threats.” The CISA Insights strongly urges leaders and network defenders to be on alert for malicious cyberactivity and provides a checklist of concrete actions that every organization—regardless of sector or size can take immediately to:
- Reduce the likelihood of a damaging cyber intrusion,
- Detect a potential intrusion,
- Ensure the organization is prepared to respond if an intrusion occurs, and
- Maximize the organization’s resilience to a destructive cyber incident.
