Application Security Checklist Before A Launch Or Update

Table of Contents

In an increasingly digital world, businesses rely on applications for seamless operations and staying ahead of the competition. However, focusing on innovation and adding new features often leaves security on the back burner. As a leading cybersecurity provider specializing in application security testing, we want to share a comprehensive checklist to help development teams avoid common vulnerabilities and protect their applications before launch or update.

Following this checklist will ensure that your organization is better prepared to tackle potential threats and safeguard sensitive data. Remember, our experts are always available to discuss your specific needs and provide tailored solutions. Contact us today.

1. Secure Development Life Cycle

Implement a secure development life cycle (SDLC) to integrate security practices throughout the development process. This includes:

  • Security training for developers
  • Threat modeling
  • Secure coding standards
  • Security testing
  • Security code reviews
  • Incident response planning

2. Authentication and Authorization

Ensure strong authentication and authorization mechanisms to protect user accounts and restrict access to sensitive data. This includes:

  • Multi-factor authentication (MFA)
  • Password complexity and expiration policies
  • Role-based access control (RBAC)
  • Secure handling of session tokens
  • Proper implementation of OAuth and OpenID Connect

3. Data Validation and Sanitization

Validate and sanitize all data inputs to prevent injection attacks, cross-site scripting (XSS), and other input-based vulnerabilities. This includes:

  • Using prepared statements and parameterized queries
  • Validating input data against a whitelist of allowed values
  • Encoding output data to prevent XSS
  • Implementing Content Security Policy (CSP) headers

4. Encryption and Cryptography

Utilize encryption and cryptography best practices to protect sensitive data, both in transit and at rest. This includes:

  • Using TLS/SSL for all network communications
  • Encrypting sensitive data stored in databases
  • Employing secure key management and storage practices
  • Implementing proper hashing and salting of passwords

5. Error Handling and Logging

Implement proper error handling and logging mechanisms to prevent information leakage and facilitate incident response. This includes:

  • Avoiding revealing sensitive information in error messages
  • Logging security-related events
  • Monitoring logs for suspicious activity
  • Implementing alerts for critical security events

6. Patch Management and Dependency Management

Regularly update and patch all software dependencies, libraries, and components to minimize the risk of vulnerabilities. This includes:

  • Establishing a patch management process
  • Monitoring for security updates and patches
  • Regularly scanning for vulnerable dependencies
  • Using vulnerability management tools

7. Penetration Testing

Conducting frequent and comprehensive pentesting remains the most efficient solution to identify and fix potential vulnerabilities in your application. Penetration testing mimics real-world attacks, based on technological standards such as the OWASP Top 10 or the MITRE ATT&CK Framework, and provides valuable insight into the various ways your application could be breached by modern hackers and how it can be prevented.
