Every business that builds or operates a mobile app must ensure it’s free from exploitable vulnerabilities. That’s where Mobile Application Penetration Testing and CERT-In guidelines come in. If your organization operates in India, following these guidelines is essential for compliance, data protection, and customer trust.
Let’s explore what CERT-In requires for Penetration Testing for Mobile Applications, why these guidelines exist, and how businesses can comply effectively.
CERT-In Guidelines for Mobile Application Penetration Testing
CERT-In (Indian Computer Emergency Response Team) provides a well-structured framework for conducting Mobile Application Penetration Testing to ensure security, consistency, and robustness of mobile applications. The goal is to identify vulnerabilities before attackers can exploit them. Below are the major areas and additional key points the testing must cover:
1. Authentication and Authorization Controls
The tester must ensure the app correctly implements secure authentication, session management, and authorization mechanisms.
Key checks include:
- Secure password handling and encrypted storage
- Proper session timeout and re-authentication after inactivity
- Role-based access restrictions and privilege separation
- Protection from brute-force or credential-stuffing attacks
- Multi-factor authentication (MFA) implementation
- Validation of secure token-based authentication (JWT/OAuth)
2. Data Storage and Transmission Security
Applications must ensure sensitive data is properly protected both at rest and in transit.
CERT-In recommends testing:
- Use of strong encryption (AES-256 or equivalent) for sensitive data
- Proper SSL/TLS configuration with valid certificates
- No hardcoded API keys, tokens, or credentials in code
- Secure use of local databases, shared preferences, and file storage
- Protection against data leakage through clipboard, logs, or caches
- Verification that data is wiped upon logout or uninstallation
3. Input Validation and Error Handling
Improper input validation is one of the most common causes of app vulnerabilities.
Penetration testing must include checks for:
- Cross-Site Scripting (XSS)
- SQL and NoSQL Injection vulnerabilities
- Command or OS injection
- XML External Entity (XXE) attacks
- Buffer overflow vulnerabilities
- Information disclosure through verbose error messages or logs
- Validation of all user inputs on both client and server sides
4. API and Backend Communication Testing
Mobile apps often rely heavily on backend APIs for data exchange. CERT-In mandates comprehensive API testing to prevent unauthorized access and data exposure.
Focus areas include:
- Token validation and secure session management
- Prevention of Broken Object-Level Authorization (BOLA)
- Implementation of rate limiting and request throttling
- Validation of proper access control for API endpoints
- Avoiding sensitive data exposure in API responses
- Ensuring HTTPS-only communication
- Input/output validation in all API calls
5. Reverse Engineering and Code Obfuscation
Attackers may attempt to decompile or tamper with mobile apps to uncover secrets or bypass security.
CERT-In mandates verifying:
- Implementation of code obfuscation and anti-tampering techniques
- Attempting APK/IPA decompilation to test resilience
- Searching for hardcoded secrets or sensitive data in code
- Presence of anti-debugging, anti-hooking, and checksum verification mechanisms
- Verification of binary integrity and signature validation
- Use of runtime protection tools (e.g., RASP, ProGuard, DexGuard)
6. Secure Configuration and Platform Permissions
Misconfigured settings or excessive permissions can lead to serious security risks. CERT-In testing ensures the app follows the principle of least privilege.
Checklist includes:
- Reviewing and minimizing requested app permissions
- Checking for debug modes, development certificates, or test URLs in production builds
- Ensuring secure API keys, tokens, and storage paths
- Disabling backup of app data unless required
- Restricting WebView usage and enforcing HTTPS in WebViews
- Verifying secure configurations in AndroidManifest.xml or Info.plist
- Ensuring app does not run on rooted or jailbroken devices (if prohibited)
- Enforcing secure keyboard input for sensitive fields (passwords, PINs)
7. Logging, Monitoring, and Incident Response
CERT-In also emphasizes proper logging and monitoring mechanisms for identifying and responding to security events.
Key checks include:
- Ensuring no sensitive data (passwords, tokens, PII) is logged
- Verification of secure log storage and access control
- Detection of suspicious activities through in-app monitoring
- Mechanisms for reporting security incidents or anomalies
8. Updates and Patch Management
Security testing must also confirm that the application supports secure and verifiable update mechanisms.
Checklist includes:
- Verification of app update authenticity (signed packages)
- Timely patching of third-party libraries or SDKs
- No use of deprecated or vulnerable APIs
In summary, CERT-In’s mobile application penetration testing framework ensures that every aspect of app security from authentication to data protection, API safety, code integrity, and secure configuration is thoroughly verified to safeguard users and maintain regulatory compliance.

How Businesses Can Prepare for Mobile Penetration Testing?
Before engaging a CERT-In empanelled auditor, businesses must ensure that their mobile application and supporting infrastructure are well-prepared for testing. Proper preparation not only streamlines the penetration testing process but also improves the accuracy of results, reduces downtime, and speeds up remediation.
Below are the key steps organizations should take to effectively prepare their mobile apps for penetration testing:
1. Conduct Internal Vulnerability Assessments
Before external auditors begin their work, it’s recommended that the internal IT or security team conducts a preliminary vulnerability assessment of the mobile application.
This internal scan helps identify obvious weaknesses that can be resolved early, minimizing false positives during formal testing.
Key actions include:
- Using automated scanning tools to detect common issues (e.g., outdated libraries, missing patches, insecure permissions).
- Reviewing code for insecure APIs, hardcoded credentials, or weak encryption.
- Validating authentication flows and access controls.
- Ensuring the app complies with internal security policies and data protection standards.
This proactive step allows your organization to enter the CERT-In testing phase with a cleaner, more secure baseline.
2. Ensure App and API Documentation Is Ready
Accurate and up-to-date technical documentation is crucial for a comprehensive and efficient penetration test. It helps the auditor understand the app’s architecture, data flow, and integration points.
Documentation should include:
- Detailed descriptions of app functionality and business logic.
- Backend architecture and server environment details.
- API endpoints with associated authentication methods and data exchange patterns.
- Third-party services, SDKs, or cloud components used within the app.
- Version control information (OS compatibility, SDK versions, and frameworks).
Well-organized documentation helps auditors plan the testing scope efficiently, minimizing confusion and saving valuable time during assessment.
3. Remove Test Data or Dummy Accounts
Before testing begins, ensure that all dummy data, test accounts, and placeholder records are removed or disabled from production environments.
Leaving test data in place can lead to:
- Misleading test results
- Unnecessary data exposure
- Potential compliance issues if sensitive data is inadvertently accessed
Recommended actions:
- Sanitize databases to retain only production-level, non-sensitive data.
- Deactivate old test user accounts, admin credentials, or API tokens.
- Backup critical data before testing to prevent accidental loss during the audit.
Maintaining a clean and realistic testing environment ensures that the findings reflect genuine vulnerabilities rather than outdated test artifacts.
4. Share Relevant Credentials and Define Scope Clearly
Transparency and clarity are essential for effective penetration testing. Businesses must provide auditors with the necessary credentials, tokens, and configuration access to perform comprehensive assessments without unnecessary restrictions.
At the same time, it’s vital to clearly define the scope of the engagement to align expectations and avoid operational disruptions.
Scope and access preparation should include:
- Sharing test credentials, API keys, or tokens with limited permissions.
- Defining whether testing includes production, staging, or both environments.
- Outlining the specific platforms (Android, iOS) and app versions under review.
- Clarifying in-scope and out-of-scope functionalities (e.g., payment gateways, third-party APIs).
- Setting communication channels for real-time issue reporting or approvals.
Proper scoping ensures the auditor focuses on relevant components, avoids business downtime, and delivers actionable insights.
The Importance of Proper Preparation
Thorough preparation before CERT-In-compliant mobile penetration testing is not just a procedural step, it’s a strategic advantage. When documentation, access, and environments are properly aligned, the testing process becomes smoother, faster, and far more accurate.
Moreover, preparation allows businesses to:
- Identify and fix simple vulnerabilities in advance
- Reduce the risk of miscommunication or delays
- Focus remediation efforts on high-priority security gaps
In short, a well-prepared organization maximizes the value of penetration testing by turning it into a proactive security improvement process rather than a reactive compliance exercise.
