Put the logging mechanism for every activity in your system and conduct a regular audit. Audit capabilities are often also required from various industry-compliance regulations. Collect logs from every component, including all transactions and each API call, to put centralized monitoring in place. It is a good practice to add a level of security and access limitation for a centralized logging account so that no one is able to tamper with it.

Take a proactive approach and have the alert capability to take care of any incident before the user gets impacted. Alert capabilities with centralized monitoring help you to take quick action and mitigate any incident. Monitor all user activity and application accounts to limit the security breach.
