• Threats of Database In E-Commerce

4. What Is Commerce
• Commerce
• CCommerce: Exchange of Goods /
Services

Security
• S

5. What is E Commerce

using computer and communication
technologies
• t Facilitated by Internet and WWW

7. Problems of E-Commerce

8. E-Commerce risks
• ECustomer's risks
• –Stolen credentials or password

• Forged or copied instruments
• –Disputed charges
• –Insufficient funds in customer’s account
• –Unauthorized redistribution of purchased
items
• i Main issue: Secure payment scheme

10. Overview
• Levels of data security
• Authorization in databases
• Application Vulnerabilities
• Summary and References

11. Levels of Data Security
• Human level: Corrupt/careless User
• Network/User Interface
• Database application program
• Database system
• Operating System
• Physical level

12. Database Threats
• Disclosure of valuable and private
information could irreparably damage a
company
• Security is often enforced through the use
of privileges
• Some databases are inherently insecure
and rely on the Web server to enforce
security measures

13. Continued
• Threats to database result in the loss or
degradation of some or all of the following
security goals: integrity, availability, and
confidentially.
– Loss of integrity
– Loss of availability
– Loss of confidentially

14. Explanation Of Threats in Database
• 1. Privilege abuse: When database users are provided with
privileges that exceeds their day-to-day job requirement, these
privileges may be abused intentionally or unintentionally.
• 3. Database rootkits: A database rootkit is a program or a
procedure that is hidden inside the database and that provides
administrator-level privileges to gain access to the data in the
database. These rootkits may even turn off alerts triggered by
Intrusion Prevention Systems (IPS).
• 4. Weak authentication: Weak authentication models allow
attackers to employ strategies such as social engineering and brute
force to obtain database login credentials and assume the identity of
legitimate database users.

15. Different Authorization
Different authorizations
for different users
Accounts clerk vs.
Accounts manager
vs.
End users

16. Database/Application Security
• Ensure that only authenticated users can
access the system
• And can access (read/update) only
data/interfaces that they are authorized to
access

17. How to protect database
• To protect database against these types
of 4 kinds of countermeasures can be
implemented:
– Access control
– Inference control
– Flow control
– Encryption
