If for some control objective there is no such evidence, first the auditor tries to see if there is some alternative way that the company handles the specific control objective, and in case such a way exists then this control objective is marked as compensating and the auditor considers that the objective is met. He is a DBA, System Architect, and Software Team Leader with more than two decades working in IT. Using these techniques improves your application's use of resources and help you stay within Cloud SQL connection limits.For more information and code samples, see Managing database connections. To enable query logging on PostgreSQL, follow these steps: Note: The following example parameter modifications logs the following: all queries that take longer than one second (regardless of the query type) and all schema changes (DDL statements regardless of completion time). I am working on an IoT project where our devices will send (one way) text (JSON) logs to our servers for storing them in DB for further our specialists analyzing. Connect any person or service to any infrastructure, anywhere, When things go wrong you need to know what happened and who is responsible, You store sensitive data, maybe even PII or PHI, You are subject to compliance standards like, No need for symbols, digits, or uppercase characters.

Once you've made these changes to the config file, don't forget to restart the PostgreSQL service using pg_ctl or your system's daemon management command like systemctl or service.

However there are some caveats: Pgaudit is the newest addition to PostgreSQL as far as auditing is concerned. An IT audit may be of two generic types: An IT audit may cover certain critical system parts, such as the ones related to financial data in order to support a specific set of regulations (e.g. Let’s give once again the INSERT, UPDATE, DELETE of the previous examples and watch the postgresql log: We observe that the output is identical to the SESSION logging discussed above with the difference that instead of SESSION as audit type (the string next to AUDIT: ) now we get OBJECT. The scope must be correctly identified beforehand as an early step in the initial planning phase. In every IT system where important business tasks take place, it is important to have an explicit set of policies and practices, and to make sure those are respected and followed.

Based on the scope, the auditor forms a set of control objectives to be tested by the audit. We have to resort to SESSION logging for this. Now that I’ve given a quick introduction to these two methods, here are my thoughts: The main metric impacting DB performance will be IO consumption and the most interesting things you want to capture are the log details: who, what, and when? Offline mode. Connection handling best practice with PostgreSQL ‎08-07-2019 03:47 PM.
