How would you prioritize addressing security vulnerabilities in a high-traffic database system?

Data is backbone of any IT system, without data, systems are meaningless. To make sure that we can save and retrieve data effectively and securely, we make use of database systems. Security is an integral part or feature of any database management system. In modern era we have to be proactive rather than reactive. So we can able to counter the high volume of security threats happening. Risk analyses is a process where we evaluate every change based on the impact it creates, and importantly take into account the unknown impacts, or uncertainities may arise. By creating counter measures for these uncertainities we make sure that we are protected.

As a proactive approach, it is very important to close any loop hole that can cause to any kind of security breach. Using effective patch management we can make sure that any zero data vulnerability will not impact us. Also any other security flaw or vulnerability is closed or take care of.

Yes, agreed. I have found more often than not that companies do not have clearly defined and regularly practiced access rights reviews. Automated provisioning can be wonderful, but the solid rule to follow is trust, but verify.

Access control process play vital role in access management processes. Broken access control will cause great damage, if not detected on time. Authentication and authotization both are very important, using RBAC to trim the permissions as required. Access control review also required frequently to avoid unwanted or orphaned permissions stays on systems. Access control process must be implemented for on boarding and off boarding processes to make sure proper rights assigned and revoked.

Encryption at rest or in transit both are usefull for data privacy and breaches. But we have to make sure we are using right algorithms and right encryption key length. Adavancement in technology is so fast that the algorithms which we think were safe 3 years ago are now breachable easily. So making sure we are using latest TLS version and latest and most secured algorithms for encryption are necessary. No compromises must be done on security hardening. If required we must update applications to work with latest TLS version and use latest encryption algorithms.

However amount of security hardening we implement or we use latest upto date devices or applications, that still will not safe us 100% from security breaches. In this case monitoring is our best friend. Keep monitor anonlmolies and unexpected connections or transactions. This will provides us opportunity to react faster and close the breach, before damage is done.
