A continuación, le indicamos cómo puede minimizar el impacto de un incidente de seguridad.

1 - Intensive training for employees of any institution, because the weakest part of the entire system is the human factor, so that they are not lured by fraudulent messages. 2- Conduct hacking reports periodically 3 - Network Segmentation 4- Use strong and paid protection programs 5- Do not download any applications outside of trusted sources 6 - Appointing a trained team for the security operations center

Prep is key, and should include: 1. Network Segmentation - don't let it spread 2. Patch Management - don't let it in. 3. Least Privilege - don't give accounts rights they don't absolutely have to have. 4. Log Analysis - collect and analyze continuously for early detection. Learn normal for your network, continuously investigate weird. 5. Data Discovery - Know where your important data is, who and how it's accessed, and what controls you can effect if the worst happens, as well as log collection so you know when something goes wrong. If you're not confident in each of the above, conduct a purple team exercise. Openly pentest while the SOC team checks to see if they can detect it, or even if they have the logs.

In the Incident Response (IR) lifecycle, the "Prepare" phase is crucial. It lays the groundwork for how effectively an organization can respond to and manage security incidents. Here's what typically falls under the "Prepare" phase: 1- Developing an Incident Response Plan (IRP): Create Policies and Procedures, Define Roles and Responsibilities, Establish path for escalating incidents. 2- Incident Response Team Formation: Form a dedicated team with diverse skills, including IT, legal, communications, and management. 3- Infrastructure and Tools: Deploy tools for detection, analysis, and response, such as SIEM , IDS/IPS , and endpoint protection. 4- Asset Management: Maintain an up-to-date inventory. 5- Stakeholder Communication Plans:

preparing for security incidents, implementing effective detection and response mechanisms, preform incidents simulation, and continuously improving incident management practices, organizations can significantly minimize the impact of security incidents and maintain business continuity in the face of evolving threats.

Preparation is perhaps the most important aspect of a proper Incident Response Plan. Develop playbooks based on real world scenarios so that you can act promptly should an incident occur. Regularly execute IR tests to ensure your policies and procedures work as expected. Finally, keep up with trends and treat all IR documents as living documents, updating every time there is a major change to business objectives or processes and annually at a minimum.

Quickly identifying a security incident is crucial to minimize its impact. Here are key steps to swiftly recognize and confirm a security incident: 1-Use security tools like SIEM to detect unusual patterns or behaviors. 2-Configure real-time alerts for suspicious activities such as unauthorized access attempts, changes to critical files. 3-Regularly review logs from firewalls, servers, and applications for signs of compromise or unauthorized activities. 4-Encourage employees to report any suspicious emails, system behavior, or security concerns immediately. 5-Understand what normal operations look like for your network and systems. This helps in quickly identifying deviations that might indicate an incident.

Conocer de manera anticipada quién es el atacante interesado y qué activos están en su objetivo permite ajustar estratégicamente la defensa cibernética. Esta información es invaluable para la gestión de ciberseguridad, ya que proporciona una ventaja al identificar y mitigar amenazas antes de que se materialicen. ¿Cuánto vale esta capacidad de anticipación en la gestión de ciberseguridad? La respuesta es simple: su valor es incalculable, pues permite proteger los activos críticos de la organización y reducir significativamente el riesgo de incidentes cibernéticos.

Implement robust monitoring and detection systems to swiftly identify security incidents. Utilize advanced threat detection tools, conduct regular security audits, and maintain real-time monitoring to quickly detect any anomalies. Early identification is crucial in limiting the damage and initiating a prompt response

Imagine que sua casa é protegida por uma cerca elétrica. Se alguém tentar invadi-la, um alarme dispara, avisando a você sobre a possível intrusão. Da mesma forma, no mundo digital, as empresas contam com ferramentas de monitoramento que funcionam como alarmes para detectar tentativas de invasão ou atividades suspeitas em suas redes de computadores. Essas ferramentas analisam o tráfego de rede e os padrões de acesso dos usuários, procurando por comportamentos incomuns que possam indicar uma violação de segurança. Quanto mais rápido essas anomalias são identificadas, mais rápido a empresa pode agir para conter o incidente e evitar que mais danos sejam causados.

Quando um incidente de segurança é detectado em uma empresa, é crucial agir rapidamente para contê-lo e reduzir os danos causados. Isso envolve isolar os sistemas afetados para evitar que a violação se espalhe para outras partes da rede. Desconectar dispositivos comprometidos ou desativar contas de usuários suspeitos são medidas importantes a serem tomadas. A contenção rápida do incidente é essencial para minimizar a exposição da empresa a possíveis ataques cibernéticos e para proteger os dados sensíveis de clientes e da própria empresa. Os empresários precisam ter a ciência da importância de agir rapidamente diante de uma violação de segurança e estejam preparados para tomar as medidas necessárias para conter o incidente.

El 28 de diciembre de 2022, el 15 de septiembre de 2023, el 11 de noviembre de 2023 y el 9 de mayo de 2024 son ejemplos de fechas en las que varias empresas lograron anticiparse a un ataque cibernético. Conocer el vector de ataque permitió a los CISOs (Chief Information Security Officers) tomar medidas preventivas para evitar la indisponibilidad de servicios, proteger la imagen corporativa y prevenir daños reputacionales a las empresas.

Once the incident is identified, act quickly to contain it and prevent further damage. Isolate affected systems, block malicious traffic, and implement measures to stop the spread of the incident. Rapid containment is essential to protect organization's data and minimize the overall impact of the security breach.

Containment in Incident Response (IR) is crucial to stop the spread of a security incident and limit its impact. Here’s a brief overview of how to effectively contain an incident: 1- Isolate Affected Systems: Disconnect compromised systems to prevent the threat from spreading. 2- Disable Accounts and Access:Temporarily disable accounts or change credentials for compromised account. 3- Network Segmentation: Use firewalls or network segmentation to quarantine affected areas 4- Stop Malicious Processes:Identify and terminate malicious processes running on compromised systems. 5- Contain Communication:Restrict outgoing communication from infected devices. 6- Patch and Update: Apply patches or updates to fix vulnerabilities.

La erradicación completa de las amenazas cibernéticas no es realista, pero lograr una visibilidad clara de la postura cibernética de la empresa es esencial. Para esto, es crucial establecer una estrategia de ciberseguridad madura. Esta estrategia debe proporcionar un nivel adecuado de preparación y capacidad de respuesta, permitiendo maniobrar eficazmente frente a eventos y amenazas cibernéticas.

Eradication in Incident Response (IR) focuses on removing the root cause of a security incident to prevent its recurrence. Here’s a concise guide on how to effectively eradicate a threat: 1- Scan and clean all affected systems to remove malware, malicious code, or any unauthorized software. 2- Apply security patches to close the vulnerabilities exploited during the incident. 3- Reinstall or restore systems from known-good backups to ensure they are free of compromise. 4- Conduct thorough checks to ensure no malicious modifications or backdoors remain. 5- Reset passwords and update access controls for any compromised accounts or systems. 6- Implement additional security measures, such as enhancing firewall rules, updating antivirus.

Todas las empresas, tanto a nivel local como global, enfrentarán un ataque cibernético en algún momento. La clave no está en evitar el ataque, sino en cómo se recupera la empresa. Un factor crucial para el éxito es realizar simulaciones constantes de recuperación. Además, los datos de respaldo y los planes de continuidad del negocio (BCP) deben estar microsegmentados y aislados del núcleo de los datos principales. Esta estrategia asegura que, en caso de un ataque, la recuperación sea rápida y eficaz, minimizando el impacto en la operación y reputación de la empresa

After resolving the incident, review what happened and improve your security policies and procedures to prevent future incidents. Continuous improvements!

It’s also necessary to maintain all the stakeholders aware of the current incident and elaborate at the end a postmortem report highlighting the areas of impact, the affected resources (technological or not), the contingency plan executed, the identified time of the incident, not just when it happened, that sometimes is uncertain, but the duration of the incident. If possible, synch the technical info with the economical and elaborate just one executive summary report about the incident. This report should be also defined in your recovery plan.

Excellent breach response hinges on transparency and rapid communication, which are crucial for maintaining customer trust during a security crisis. Consider Okta and Cloudflare: - Okta's handling of incidents often resulted in lost customer trust. - Cloudflare turned potential crises into opportunities, sometimes gaining new customers. Key takeaway: CISOs should align their public communications team, legal department, and themselves well before any incident occurs. This preparation enables a swift, transparent response modeled after Cloudflare's approach rather than Okta's.

Always plan for a breach and be proactive rather than reactive about it. Be sure to have incident response plans (IRP) in place but also be sure to enact and test them to learn about ways to constantly evoke and improve them. I always recommend table top exercises when you can do them. There is no one-size fits all. It is highly important to have e communication plans in place not only for the teams but also for the leadership, human resources and the corporate communication teams for example. Additionally, having updated contacts for primary and backup contacts is very essential. Constantly work on your plans and incorporate findings & lessons learned to constant evolve them!

Documenting everything during a security incident can minimize its impact. By keeping detailed records of what happened, actions taken, and the decisions made, we make sure that nothing is forgotten. This helps in understanding the incident, avoiding repeated mistakes, and improving future responses.

Minimizing the impact of a security incident involves thorough preparation, rapid detection, effective response, and continuous improvement. By developing a robust incident response plan, regularly training staff, implementing strong security controls, and learning from past incidents, organizations can significantly reduce the damage caused by security breaches and recover more quickly

Use established framework like ISO 27035 or NIST Cyber Security Framework, then develop and customize to your need. Start from Process (policy, incident response plan, procedure, and their derivatives; also overall management), to People (build team, awareness, training), and Technology/Platform (tools). Don't forget about internal relations (involving top management, legal, HR, ...), external relations (vendors, external experts, journalist, ...). Prepare Press Release template. Establish trust and alternate communication channels. Some process might reside outside of incident response team (backup, SOC, ...) so be aware of those relation/dependency in preparation and so on.
