Incident management and cyberattack response plan

Strengthening cyberattack response capabilities in the healthcare sector

Cyber-Tower partnered with a healthcare organization to design and implement an Information Security Incident Response Plan (ISIRP). The objective was to establish a clear, operational strategy against cyber threats that could compromise availability and confidentiality of clinical data.

Initial situation

The institution had experienced security incidents that disrupted critical medical systems and patient records. There were no formal procedures or defined roles for incident response, resulting in delayed reaction times and reliance on third parties.

Methodology and approach

• Initial diagnosis of incident management maturity.
• Design of the response workflow based on NIST 800-61r2 (Computer Security Incident Handling Guide).
• Definition of roles and responsibilities within the Internal CSIRT.
• Implementation of a centralized event logging and monitoring system.
• Incident simulation exercises to validate reaction times and communication flow.

Results and benefits

The organization reduced its detection and containment times for critical incidents by over 50%. Standardized procedures and automated escalation rules were implemented. The response plan was aligned with business continuity and cyber resilience strategies.

“We now have a clear structure to respond to any cyberattack. Cyber-Tower’s preparation and support made a significant difference in our response capability.”

Key lessons

The experience highlighted that organizational preparedness and effective internal communication are essential for successful incident management. Technology alone is not enough—people were a critical component of the response.

Next steps

The plan includes biannual simulations and the adoption of a SIEM platform to improve threat detection. Cyber-Tower continues to support the organization in continuous process improvement.
