Backup Critical Data: Before starting the upgrade, ensure all critical data is securely backed up to prevent loss in case of unexpected issues. For example, a retail startup upgrading its system backed up its entire customer database and transaction history to a cloud platform. During the upgrade, a glitch temporarily wiped out local data, but the backup ensured business continuity without any customer impact. Backing up regularly not only safeguards data during upgrades but also demonstrates professionalism and reliability to clients and stakeholders. It's a simple yet crucial step in maintaining network security and trust.

Deploy Zero Trust Architecture: Implement a Zero Trust model to ensure that every access request is verified, authenticated, and encrypted, regardless of whether it originates inside or outside the network, minimizing vulnerabilities during the upgrade.

Durante uma grande atualização de sistema, deve-se priorizar a segurança da rede. Primeiramente, é importante realizar uma auditoria completa de segurança para identificar vulnerabilidades. Em seguida, implementar controles de acesso rigorosos, autenticação multifator (MFA) e criptografia de dados. Utilizar firewalls e sistemas de detecção de intrusões para monitorar a atividade da rede em tempo real. Além disso, fazer backups regulares e testar os planos de recuperação de desastres. Treinar todos os funcionários sobre práticas de segurança cibernética é essencial. Essas etapas são cruciais para proteger a integridade da rede durante a atualização.

Ensuring network security during a system upgrade requires careful planning and robust measures. Start with a detailed risk assessment using tools like Nessus to identify vulnerabilities and address them beforehand. Implement VLANs and Role-Based Access Control (RBAC) for network segmentation, minimizing the impact of potential incidents. Strengthen access with Multi-Factor Authentication (MFA) through solutions like Duo or Azure MFA. Keep systems updated using tools like SCCM or Ansible to mitigate known vulnerabilities. Leverage monitoring platforms such as Splunk for real-time threat detection, and always test upgrades in a controlled environment to identify issues before deployment.

First of all prepare a Backup/Snapshots of your mirror Pre environment. Next step, upgrade it in the same way you'll do the Pro to ensure the viability of the upgrade. After that you must stress the Pre environment to detect any issues or bugs. In case of any issue, check for workaround solutions and restore snaps and retry the upgrade with the workarounds until you get a clean upgrade to move it to the Pro environment. This is not warranty for a safe transition, a new possible issues can appear, but they'll be less critical, be always prepared to solve it.

A big part of the development lifecycle that gets ignored way too often is testing. I cannot stress enough how important it is to work the bugs out in a sandbox environment before pushing any system upgrades to production. It is better to take the schedule hit in testing, than it is to risk your company’s reputation and the data of your customers. Test, test, test, then test some more!

Haga un estudio y análisis de riesgos antes de implementar un upgrade de sus sistemas y productos, donde tenga un plan de seguridad en caso de problemas, virus y malware. Siempre este actualizado en seguridad para su empresa y sus clientes, haga updates y parches regularmente.

To ensure network security you need to have a strategy plan in place to assess any potential risks and eliminate any potential jams. Always follow the designs built and implement a step-by-step migration plan. Once this is all done, definitely have to test and evaluate the work. And always keep in mind to exercise your information technology team and keep them in the know for any upgrades that need to be done or emergency security issues that might come up in the future.
