Una auditoría profunda de sistemas ayuda a detectar el origen y un monitoreo continuo hace que las defensas se mantengan fuertes. Desde mi experiencia, los equipos actúan de manera rápida ante este tipo de situaciones logran proteger su red y fortalecen la confianza del cliente.

Follow these steps to secure your network and data effectively: -Disconnect compromised systems from the network. Investigate the scope, entry point, and affected areas to understand the impact. -Fix vulnerabilities by updating software, firmware, and security configurations. -Enforce strong passwords, multi-factor authentication (MFA), and role-based access control (RBAC). -Enable detailed logging and use monitoring tools to detect and respond to suspicious behaviour. -Ensure data is encrypted both in transit and at rest to reduce exposure. -Review system settings, permissions, and configurations to eliminate weaknesses. -Inform employees about the breach and train them on recognising potential threats.

Assess the Situation: Identify the nature and scope of the breach. Determine which systems and data were affected. Contain the Breach: Isolate compromised systems to prevent the breach from spreading. Disconnect affected devices from the network and change passwords1. Notify Key Stakeholders: Inform internal teams, management, and external partners who might be affected. Transparency is crucial in maintaining trust1. Implement Security Measures: Use firewalls, intrusion detection systems, and network segmentation to enhance security. Apply security patches and update credentials1.

Good luck. My rule is simple, "Millions of hackers are always smarter than one of me, so hacks will occur repeatedly. Only question is how to design backups + transaction roll forwards (sales payments), so they can be applied quickly. When hacks occur -> pause systems with maintenance message, restore a backup, go through roll forward, figure out how to block future hacks, bring system back online for users. This usually requires some use to this type of design to ensure your recovery process is rock solid + fast.

To protect your network and data after a security breach, immediately isolate affected systems to contain the threat and investigate to identify its origin and scope. Apply patches to vulnerabilities, restore systems using clean backups, and implement enhanced security measures such as firewalls, multi-factor authentication, and real-time monitoring. Conduct a comprehensive review of security protocols to prevent future incidents.

En diferentes oportunidades, al detectar una inseguridad o vulnerabilidad en sistemas de información, se procede a monitorear el tráfico de la red y en ese mismo instante se revisan todos los permisos vigentes a fin de poder identificar algún permiso sospechoso y bloquearlo

Following a security breach, I act swiftly by immediately changing all passwords and enforcing multi-factor authentication to strengthen access security. A comprehensive audit identifies the breach’s origin and addresses vulnerabilities. Regular updates and continuous monitoring of security systems are then implemented to prevent future incidents. This proactive and structured response ensures the network and data are effectively safeguarded against further threats.

Primeiro passo é isolar os sistemas comprometidos para conter a ameaça, seguido de uma análise ou auditoria para identificar a origem do ataque e até onde foi comprometido. Revogaria credenciais comprometidas e reforçaria autenticações. Necessário definir uma estratégia para fazemos um DRP e realizar um monitoramento contínuo, ajustando políticas de segurança e treinando a equipe para prevenir futuras violações.

To secure your network and data, disconnect compromised systems, investigate the breach's scope, and address vulnerabilities through updates and configuration changes. Enforce strong passwords, MFA, and RBAC. Enable detailed logging, monitor for threats, encrypt data, review system permissions, and educate employees on recognizing and responding to potential security risks.
