Testing Plan

Step 1: Analyze the Authentication Module Code

 Examine the input handling functions to ensure that user inputs are validated and
sanitized.
 Identify logical paths within the authentication process, including user registration, login,
and session management.
 Review password handling mechanisms, such as encryption and storage.
 Check for potential hardcoded credentials or sensitive information.
 Analyze error messages to ensure they do not leak sensitive information.

Step 2: Identify Vulnerabilities

 Input Validation Issues: Lack of validation for username and password fields.
 SQL Injection: Inspect code for any unparameterized database queries.
 Password Handling: Ensure secure password hashing algorithms (e.g., bcrypt) are used.
 Session Management: Verify that sessions are properly created, managed, and
invalidated.
 Error Message Disclosure: Ensure error messages do not reveal if the username or
password is incorrect.

Step 3: Design Test Cases

Test Case Actual


Test Description Expected Outcome Status
ID Outcome

TC_001 Login successful

Attempt SQL injection in the login
TC_002 Block the attempt
field
Validate password encryption Password securely
TC_003

Test login with invalid
TC_004 Show generic error message
username/password combination
Check for session timeout after a Session expires and user is
TC_005
defined period logged out
Verify no hardcoded credentials No hardcoded credentials
TC_006
exist in the codebase found
Test error message for password Show generic error without
TC_007
recovery revealing sensitive details
Validate handling of special
TC_008 Input properly sanitized
characters in input fields

Step 4: Execute Test Cases


 Run each test case using both automated and manual testing techniques.
 Document any failed test cases and report security vulnerabilities to the development
team.

Step 5: Recommendations

 Implement input validation functions to sanitize user inputs.


 Use parameterized queries to prevent SQL injection.
 Ensure password hashing and salting with industry-standard algorithms.
 Establish secure session management practices.
 Review and refine error handling mechanisms to protect sensitive information.
