so, the things need to follow on critical IT incident 1. Check for detail case study, why it happened 2. The cause need to identify and check the vulnerable area. 3. Improve the monitoring on IT Infrastructure, probably configure SIEM tool for monitoring 4. Incident report need to create, submit with cause and how to avoid this in future 5. Make that critical logs are getting monitored 6. Keep your IT Infrastructure equipment and applications security patch updated

1. Conduct a thorough Root Cause Analysis to pinpoint the cause. 2. Hold a Post-Incident Review with an open, blame-free culture to learn and improve. 3. Document every detail and share knowledge with your team. 4. Implement monitoring tools with alerts for early detection. 5. Regularly train your team and simulate crisis scenarios. 6. Regularly update processes based on new insights. 7. Invest in robust IT infrastructure for redundancy and recovery.

hmmmm....So .. 1-Conduct a Post-Incident Review (Root Cause Analysis), 2-Strengthen Incident Response Process, 3- Implement Preventative Measures, 4- Security Enhancements , 5- Continuous Improvement, 7- Change Management.

Primeiro passo é ter uma determina??o clara do que é incidente crítico e ter um processo para tal. Após um incidente crítico, importante a realiza??o de um Post Mortem, para analisar detalhadamente o incidente: entender o que deu errado e o que podemos fazer de melhor para aprender com o ocorrido. Registre um ticket de problema e atrele a prioridade do incidente ao problema. Os insumos coletados no Post Mortem devem alimentar o ticket de Problema. A gest?o de problemas transformará os insights do post mortem e atuará na analise de causa raiz para garantir que o incidente nao ocorra novamente. Assim criando uma cultura de aprendizado, melhoria contínua, resiliência de servi?os de ti e inova??o na empresa.

Fix the Immediate Issue Ensure that the problem is fixed and tested thoroughly. Patch and Update Systems Apply patches or updates to vulnerable systems to avoid recurrence of the same issue. Update Configurations Review and update configurations that may have contributed to the incident.
