- The Problem
- A Major challenge in eGov : Data Management
- E.g. Land Records , Citizen Database etc.
- Content Manager : a Possible Solution
- What is Content Manager ?
- Content Manager (a product from IBM) is a scalable solution for storing
and retrieving documents of various types.

- Brief Overview of the features of CM
- 1. Lets you store content regardless of format.
( Unstructured data )
- E.g. text documents, scanned images, audio, video, forms any binary
object
- 2. Stores data on distributed servers and provides single point access.
- 3. Provides many sophisticated features like
- Access control
- Storage management – Archiving , Purging , Migration
- User management
- Automated Workflow
- Enterprise wide search from Internet or intranet clients.
- Streaming audio and video.

- Definition of Audit Trail
- An audit trail is a series of records of computer events, about an
operating system, an application, or user activities.
- Purpose of Audit Trail
- Individual Accountability: track individual actions to facilitate
audit.
- Reconstructing Events: reconstruct events as and when required.
- Problem Monitoring: online tools to help monitor problems
- Intrusion Detection: identifying attempts to penetrate a system and
gain unauthorized access.

- Audit Trail Component : A module responsible for managing the audit
trail of eGov applications across the entire system.
- Problem Description
- Where can we place the Audit Trail Component in the eGov Architecture ?
- Possible options:
- Application
- In the Middleware , above DV Module
- In the Component Databases
|

|
- Security Issues
- Risking security at the hands of applications
- Tamper proofing of Audit Trail
- Implementation Issues
- Application Complexity
- Database design Complexity
- Audit Trail Transparency to the application developers
- Consistency of Audit Trail across the entire system
- Ease of Audit Policy Management

- Audit Trail Agent Architecture
- Storage of Audit Trail is an issue
- Distributed or Centralized ?
- Possible Solution:
- A Buffered Distributed - Centralized Architecture
- Amalgamation of audit trail data at the central server
- Timestamping issues to ensure correct chronological sequencing of
audit trail for analysis – Time sync , which time to use
- Proper Categorization of Audit Trail data to facilitate analysis
- Ensuring Tamperproofing of Audit Trail for the Auditor
- Authentication of Distributed Sources
- Encryption
- Access Control
- Secure Transmission
- Audit trail management (Archiving and purging)
- Access Control to Audit Trail
