Challenges

Following are the challenges faced by the database security system -

(1) Data Quality

• The database community need the solution to assess the quality of data. The quality of data can be assessed by a simple mechanism such as quality stamps that are posted on web sites:

• The database community may need more effective technique of integrity semantic verification for accessing the quality of data.

• Application level recovery techniques are also used to repair incorrect data.

(2) Intellectual Property Rights

• Everywhere there is increasing use of internet and intranet. Due to which there are chances of making un-authorized duplication and distribution of the contents. Hence digital watermarking technique is used to protect the contents from unauthorized access or ownership.

• However, research is needed to develop the techniques for preventing intellectual property right violation.

(3) Database Survivability

• It is desired that the database systems must continue to work even after information warfare attacks.

• The goal of information warfare attacker is to damage the organization's operation.

• Following are the corrective actions for handling this situation -

    • Confinement : Take immediate action to eliminate attacker's access to the system. Isolate the affected components to avoid further spread.

    • Damage Assessment: Determine the extent of problem.

    • Reconfiguration:Re-configuration allows the system to be in operation in degraded mode while recovery is going on.

    • Repair:Recover the corrupted or lost data by repairing or reinstalling the system.

    • Fault treatment: Identify the weakness exploited in the attack and take steps to prevent a recurrence.
