We know that security and speed are two properties that often require trade-offs, sacrificing one to optimize the other. However, we can ensure security indirectly across the entire system while maintaining performance. This can be achieved by applying minimal security measures to each component where possible. Each layer of a security system is like a slice of cheese. There may be a hole in each slice, but when stacked together, light cannot pass through. These layers are not just individual system components, but also monitoring, access control, security protocols, and periodic audits.

? First, figure out where the client’s data is most vulnerable, e.g. during transmission, transfer or when it is stored ? Encrypt Everything: From information in transit to data at rest, if it’s sensitive it should be encrypted ? Limit the number of users who can access the system by only allowing those who are authorised. Use RBAC (role-based access control) for domains where excess data access can have a negative impact on the business ? Optimise Securely: Work on optimising performance but, when applicable, always do so in a fashion that does not undermine nor compromise security ? Continuous Monitoring: Configure real-time 24 X 7 monitoring capabilities to check for security breaches as well as overall system performance

To optimize system performance while prioritizing client data security, I implement a multi-layered approach. First, I ensure data encryption both in transit and at rest, using advanced cryptographic algorithms. Role-based access controls are established to limit data exposure to authorized personnel. Regular vulnerability assessments and security patches prevent breaches. Additionally, I implement auditing and monitoring tools to track any unusual activities. This balance of security protocols and performance optimization ensures that client data remains protected without sacrificing system efficiency.
