Assessing Application Security for a FinTech Start-up
Business Requirement
The business requirement was to conduct an application security review within a UK-based FinTech start-up. The objective was to assess the current state of application security, identify any deficiencies and vulnerabilities, and offer actionable recommendations for improvement.
Nuage Solution
To fulfil the Fintech’s requirement of an application security review, Nuage security expert took a comprehensive approach to assess the organization’s information security maturity. The first step involved conducting an application security review, which included a grey box penetration testing approach. Information gathering phase was organized to examine the application architecture and security implementation.
Nuage conducted network scanning and vulnerability analysis to identify any weaknesses or vulnerabilities. Upon discovering potential vulnerabilities, Nuage actively focused on exploitation and remediation to gain a comprehensive understanding of the risks and device effective strategies for addressing them.
Specific tests that helped in addressing the key areas of concern are:
Broken Authentication
To identify any vulnerabilities that could lead to authentication bypass, allowing unauthorized access to sensitive areas of the application.
Authorization
This involved examining unauthorized access attempts and assessing the implementation of appropriate authorization controls. Additional tests to detect vulnerabilities related to access control, including the potential risk of privilege escalation.
Business Logic Testing
Nuage performed a comprehensive business logic test to evaluate the application’s functionality and identify any flaws that attackers could exploit.
API Testing
To ensure their protection against common API vulnerabilities, including injection attacks, unauthorized access, and improper input validation.
Input Injection
Nuage tested for various types of input injection vulnerabilities, to identify potential weaknesses in the application’s input validation and processing mechanisms.
Session Management
The security of session management was evaluated to verify that sessions were adequately protected against session hijacking or fixation attacks.
Weak cryptography
Nuage performed weak cipher scans to identify any vulnerabilities in the SSL/TLS configuration and assess the overall security of the encryption.
Client site testing
Nuage conducted client site testing which aimed to prevent attacks, unauthorized access to sensitive resources, and ensure data protection.
