- 11. © Techcello www.techcello.com Web application top threats • Man in middle attack • Use secure channel - https • SQL Injection • Use parameterized queries • Malicious script injection and Cross Site Scripting • Validate input if it is a safe HTML • URL escape, Html escape and Javascript escape untrusted data • Cross site request • Challenge-Response such as CAPTCHA • Synchronizer Token • Origin header OWASP – open web application security project
- 12. © Techcello www.techcello.com Encryption • Preferred Symmetric compared to asymmetric due to performance • Use Strong Keys • Change Keys Periodically Key storage • Store in Key Vault and store away from encrypted data • Double encryption • Dual key storage Database encryption • Watch for Performance implications • Encrypt only necessary columns Data Security – Data Storage

- 15. © Techcello www.techcello.com Event Audit • Covers • Who does the action? • What action is performed? • What is the context in which the operation is performed? • What time is the action performed? • Event audit information – subject, target, context, user, datetime • Audit details stored in a separate datastore for better performance • Realtime audit details – audit cache server Security Audit
- 16. © Techcello www.techcello.com Transaction and Change Audit • Transaction Audit • Snapshot: Exact copy of the row stored in history tables • More suitable if requests to access past data are more • More data growth • Change Audit • Only the delta of the state change captured as part of change tables • More suitable when changes need to be reported and past data are not required much • Used more for Security tracking purposes • Easier to implement by using methods available out of the box in RDBMS such as CDC for SQL server • Asynchronous Mode : For better performance and if we wish that audit should not roll back the transactions it is advisable to audit in a asynchronous thread.
