They should possess the ability to easily track or identify potential fraud or anomalies end-to-end. Environments Affected All. Relevant COBIT Topics DS11 – Manage Data – All sections should be reviewed, but in particular: DS11.4 Source data error handling DS11.8 Data input error handling Description Error handling, debug messages, auditing and logging are different aspects of the same topic: how to track events within an application: Best practices Fail safe – do not fail open Dual purpose logs Audit logs are legally protected – protect them Reports and search logs using a read-only copy or complete replica Error Handling Error handling takes two forms: structured exception handling and functional error checking. Structured exception handling is always preferred as it is easier to cover 100% of code. On the other hand it is very hard to cover 100% of all errors in languages that do not have exceptions, such as PHP 4. Code that covers 100% of errors is extraordinarily verbose and difficult to read, and can contain subtle bugs and errors in the error handling code itself. Motivated attackers l
