You're facing a network outage crisis. How do you protect sensitive data during the restoration process?

Here’s a concise guide with examples: 1. Data Classification: Highly Sensitive: Personal identification Sensitive: Financial data Non-sensitive: Publicly available information 2. Risk Scenarios: Scenario 1: A database breach exposes customer profiles. Impact: Reputation damage, legal penalties. 3. Mitigation Strategies: Encryption: Encrypt sensitive files to prevent unauthorized access. Regular Backups: Frequent backups minimize data loss risk. Access Controls: Limit access based on roles 4. Prioritization: Critical Data: Restore high-priority data first Secondary Data: Less critical data

é sempre necessário avaliar os riscos antes de qualquer processo, para que dessa forma a margem de erros sejam minimizadas em projetos.

Com 20 anos de experiência como analista de suporte, enfrentei diversas crises de interrup??o de rede. Proteger dados confidenciais é essencial durante essas situa??es. Minha abordagem inclui implementar criptografia de dados e autentica??o multifatorial, garantindo que apenas pessoal autorizado acesse os sistemas. Backups regulares e seguros também s?o fundamentais para recupera??o rápida e segura. Monitorar o tráfego da rede para atividades suspeitas e usar ferramentas de detec??o de intrus?o s?o práticas essenciais. A comunica??o clara com a equipe sobre os protocolos de seguran?a é vital para minimizar riscos e manter a integridade dos dados, mesmo em crises.

Identifying and prioritizing data should be done prior the incidence. A good organization should already have a comprehensive priority list about the stored data. So when a breach happen, we can focus on the next step.

During a network outage crisis, protecting sensitive data is crucial. First, ensure all data is encrypted, both at rest and in transit, using strong encryption protocols. Disable access to critical systems and data to prevent unauthorized access. Use secure backup solutions and verify their integrity before restoration. Implement multi-factor authentication (MFA) for accessing backup systems. Monitor all network activity for suspicious behavior. Communicate clearly with your team and follow your incident response plan. Document all actions taken for auditing and future reference. For detailed strategies, refer to the incident response section of the CySA Project on my LinkedIn Page.

In my experience, disconnecting all the network and restore the trusted connection one by one proved to be the most efficient way to secure access.

Concordo, uma vez que os dados armazenados est?o em nuvem, s?o abertas diversas comodidades para acesso. Como utilizar outros dispositivos, também pela seguran?a que nos traz em caso de danos no componente de armazenamento físico.

Actually that statement is very effective for prevent the Incident that might be harmful. But there are other factor that might be helpful, that factor is to implement the automation to minimize our monitor activity, automation help to minimize human error when me as a dev or ics doing the monitoring activity

A comunica??o clara permite objetividade nas tarefas do dia a dia, na execu??o de escopos determinados. A compreens?o e obten??o de informa??es importantes para a??o.

First and foremost, be sure you have a good, recent backup. Everything else (hardware and software) can be repaired but the data is the most important item. Data is the equivalent of the King on a chessboard; you can afford to lose everything else. Most operating systems and software has some sort of checksum routine to ensure the integrity of the data. Be sure to let them run through their checks completely before giving users access. Of course, there's physical control to physical data access as well. You must be vigilante in controlling access to facilities, the associated software, hardware and data. Permissions to software and hardware, must be strictly controlled, monitored and restored promptly. Some sort of audit trail is important.
