You're expanding your database capacity. How can you ensure data security and integrity?

Plan Ahead: Develop a comprehensive data security strategy during the expansion phase, including risk assessments, security protocols to address potential threats. Encrypt Data: Implement robust encryption both at rest and in transit. Ensure that sensitive data is always protected by using industry-standard encryption algorithms to prevent unauthorized access Manage Access: Enforce strict access control policies by granting the least privilege required. Use role based & multi-factor authentication Monitor Activity: Set up continuous monitoring of database activity using tools that track access logs, identify unusual behavior Backup Regularly: Schedule automated & encrypted backups to ensure data is recoverable in case of failure

As your system grows and evolves, so should your expansion plan. Schedule regular reviews of your plan to ensure it remains aligned with your current and future needs. Technology, security threats, and organizational goals can change over time, and what was sufficient yesterday may not be adequate tomorrow. By periodically reassessing and updating your plan, you can address emerging security challenges, optimize performance, and ensure that your infrastructure scales smoothly. This proactive approach minimizes risks and ensures that your system remains resilient and secure as it expands.

1. Plan Ahead - Plan in advance and ensure that the database will contain the required integrity and security. 2. Encrypt Data - Implement encryption techniques associated with the classifications of the data contained within the database. 3. Manage Access - Within the planning, managed access must be guaranteed where only authorized people can access certain data. 4. Monitor Activity - Activities must be monitored in order to maintain control over information security and management. 5. Backup Regularly - Backup must be regular to ensure incident control management. 6. Validate Integrity - Data integration must be validated to keep its validation up to date.

To ensure data security and integrity when expanding database capacity: Implement robust access controls and authentication mechanisms Encrypt sensitive data both in transit and at rest Regularly back up data to prevent loss in case of failures Conduct thorough security audits and vulnerability assessments Enforce data validation and normalization rules to maintain data consistency.

While encryption is essential, the security of your data also depends heavily on how you manage your encryption keys. Implement a regular key rotation policy to further protect your encrypted data. Key rotation involves periodically replacing encryption keys with new ones, which helps limit the amount of data that could be compromised if a key is exposed. Ensure that your key management system supports automated key rotation without disrupting access to your data. By rotating keys regularly and securely, you add an extra layer of defense, making it more challenging for unauthorized parties to decrypt your sensitive information.

Usar padr?es fortes como AES para dados em repouso e TLS para dados em transito é fundamental, porém, a seguran?a vai além da criptografia em si. A gest?o das chaves é igualmente importante. Implementar uma política de rota??o de chaves, onde você troca as chaves periodicamente, pode limitar os riscos caso uma chave seja exposta. é ideal que o sistema de gerenciamento de chaves suporte essa rota??o de forma automatizada, garantindo que o acesso aos dados n?o seja interrompido. Ao fazer isso, você adiciona uma camada extra de prote??o, tornando mais difícil para pessoas n?o autorizadas a terem informa??es sensíveis e fortalecendo a seguran?a do seu sistema.

Encryption is essential for database security. As you expand, ensure data is encrypted to keep it unreadable without proper decryption keys. Use strong standards like AES for data at rest and TLS for data in transit. Manage encryption keys securely with a centralized key management system to prevent unauthorized access.

To streamline and enhance the management of user permissions, consider implementing Role-Based Access Control (RBAC). RBAC allows you to assign permissions based on the roles within your organization, rather than on an individual basis. This not only simplifies the process of granting and revoking access but also ensures that users automatically inherit the appropriate permissions when their role changes. Additionally, RBAC makes it easier to enforce the principle of least privilege, as each role is carefully defined to include only the necessary permissions. Regularly audit and adjust roles to ensure they continue to align with your security policies and organizational needs.

Identity and Access Management is a key service where limiting access to the data only for those who actually requires it rather than providing it to everyone. Row based Access - Nowadays companies are focusing more on Row based Access. An Example is that if a person from US tries to run a query it will display only the records related to US and not about other countries.

Emphasize the importance of continuous monitoring to detect and respond to security incidents quickly. Suggest using automated tools for threat detection and access log auditing. Highlight the need for regular log reviews to identify any anomalies or potential security breaches

When it comes to Monitoring. , We have to Manage multiple jobs and workflows. Creating a proper dashboard about the status of the jobs and Setting up an alert system to Teams or Creating an incident in Service now whenever a job fails in production will help in Streamlining the Monitoring as it is a 24/7 activity, Automating these key areas will definitely help in reducing the work and effort in the long run.

Stress that regular backups are essential to prevent data loss or corruption. Recommend keeping multiple copies of backups in different locations, including off-site or cloud-based options. Advocate for regular testing of backups to ensure successful restoration and maintained data integrity

Implantei um plano de a??o para automa??o de backups de dados na empresa. Desenvolvi um script backup.sh que utilizava pg_dump para exportar o banco de dados PostgreSQL, armazenando os arquivos com a data atual e mantendo apenas os últimos sete backups. Programei a execu??o automática do script via cron, todos os dias às 2 da manh?, e configurei a transferência dos backups para um servi?o de nuvem. Além disso, realizei testes de restaura??o mensalmente para garantir a integridade dos dados. Essa estratégia assegurou a prote??o contra a perda de dados e a prontid?o para eventuais incidentes.

Fault Tolerance or DLP - Data Loss Prevention is an important Factor to consider while designing a pipeline System. Creating awareness among Data Engineers regarding the impact of delete statements so that proper delete statements will be queried instead of Deleting the entire attribute or Table. Maintaining a Snapshot or History table will help in recoveing the data that has been lost.

Mention that regular data integrity checks should be a fundamental part of database management practices. Suggest integrating integrity validation into routine operations to identify and correct potential issues early
