1 Initial Response

As soon as you detect a cyber attack, your immediate response is critical. First, isolate affected systems to prevent the spread of the attack. This may involve taking servers offline or disconnecting from the internet. Then, engage your incident response team to assess the scope and impact of the breach. Communication is key during this phase; keep stakeholders informed without causing panic. Ensure that you document all actions taken, as this will be invaluable for post-incident analysis and potential legal considerations.

Deben tener un plan de respuesta a incidentes estructurado, y con prácticas para actuar rápidamente. Identificar y aislar la fuente del ataque para evitar que se propague en la red. Hay que desconectar los sistemas comprometidos y revisar los registros de actividad para dimensionar el daño. Restaurar los sistemas afectados y las copias de seguridad limpias de infecciones, aplicar parches de seguridad para eliminar las vulnerabilidades explotadas. Deben comunicar a las partes afectadas sobre el incidente y medidas que se están tomando. Realizar una evaluación post del incidente y saber causas y fortalecer las defensas cibernéticas. Sumar medidas de monitoreo y detección de amenazas y considera la posibilidad realizar auditorías externas.

2 Assess Damage

Once the immediate threat is contained, you must evaluate the damage caused by the cyber attack. This involves identifying which data was compromised, the extent of system damage, and how business operations have been affected. You'll need to conduct a thorough investigation to understand the vulnerabilities exploited and whether any malware remains in your systems. It's also essential to consider the legal implications, such as data breach notification laws, which may require you to inform affected parties.

3 Restore Systems

The next step is to restore your systems to normal operation. This usually involves cleaning infected systems, repairing damaged files, and restoring data from backups. Make sure your backups were not compromised and are free of malware before using them to restore systems. In some cases, you may need to rebuild systems from scratch to ensure they're secure. During restoration, maintain transparency with customers and partners about when they can expect normal service to resume.

4 Update Security

After a cyber attack, it's crucial to update and strengthen your security posture to prevent future incidents. This could involve updating software and hardware, changing passwords and access controls, and implementing additional layers of security like two-factor authentication. Educate your employees about new security protocols and the importance of cybersecurity hygiene. Regularly review and update your security measures to keep up with evolving threats.

5 Business Continuity

Business continuity planning is essential to minimize downtime during a cyber attack. This includes having a plan for operating your business during a disruption and strategies for quick recovery. Review your business continuity plan in light of the attack, making necessary adjustments based on lessons learned. Ensure all team members are familiar with the plan and their roles within it, which will enable a more effective response to any future incidents.

(DR) in a security incident and recovery from a disaster (or major disruptive event) as quickly and securely as possible. Business continuity and disaster recovery are quite often referred to in the same breath, but you must understand the role that each plays. A business continuity plan (BCP) is a methodology and set of protocols that deals with allowing an organization to keep its key business functions running in the event of a crisis; this is sometimes referred to as continuity of operations (COOP). Business continuity includes all of the preventative controls and the management A disaster recovery plan (DRP) is a set of processes that deal with restoring your information systems and operations, securely and efficiently.

6 Learn and Adapt

The final step in recovery is to learn from the cyber attack and adapt your practices accordingly. Conduct a post-incident review to identify what worked well and what didn't in your response. Use this information to improve your incident response plan and security measures. It's also beneficial to share your experiences with other businesses, as collaboration can lead to stronger defenses against common threats.

Initiate the BCP in place and follow the course of action per IRT (Incident Response Team). Alert system are available to monitor and analyse the magnitude of impact which can be quantified in order to prevent the intended attacks.

Get the basics right. Do those updates for the patch management, configure the firewalls, check the configuration on your anti-malware products and layer the defences. Identify your critical assets and implement an effective incident response process, get the stakeholders and business units involved. Then train and practise. A desktop scenario is acceptable and better than nothing. Look to continually improve the process.
