Banking App Security Testing: Techniques and Tools
The financial sector ranks second in global cyber incident damage statistics, surpassed only the healthcare industry, according to the 2023 IBM’s Cost of a Data Breach Report. Financial organizations experience losses averaging around $5.9M per cyber incident, exceeding the cross-industry average of $4.45 millionThe sector is a prime target for cybercriminals as they hold a goldmine of sensitive data which can be used for various malicious purposes, like targeted phishing attacks or financial fraud. Moreover, cybercriminals can directly steal money from financial institutions through various means, like wire transfers, account takeovers, and ATM skimming. As they also manage fund access, financial institutions are often willing to pay hefty ransoms to get their critical data back compared to other potential victims
With that being said, banking application security testing plays a pivotal role in keeping financial institutions safe from cyber threats and staying one step ahead of hackers. In this article, we’ll explore everything you need to know to enhance your defense.
With this type of testing, teams usually leverage automated scanning tools to scan systems such as servers, routes, and endpoints against predetermined vulnerabilities
During a vulnerability assessment, you can categorize identified security weaknesses based on their type, severity level, etc., based on these frameworks:
- OWASP Top 10 Application Security Risks.
- OWASP Top 10 Mobile Risks.
- Open Web Application Security Project (OWASP) Testing Guide.
- Web Application Security Consortium (WASC) Threat Classification.
- Common Vulnerability Scoring System (CVSS).
Penetration testing entails replicating the techniques employed by a real-world attacker to gain access to a company's data, applications, or IT infrastructure. The objective of penetration testing services is to pinpoint security vulnerabilities within an IT environment, assess their potential impact, and provide guidance for remediation.
Code review encompasses both manual and automated examination of application source code to identify flaws such as encryption errors, buffer overflows, XSS, and SQL injection vulnerabilities. It can help enhance source code performance, scalability, maintainability, and clarity, while also fortifying software against potential cyberattacks.
Conducting a compliance assessment is instrumental in identifying and addressing deficiencies in a company's policies, procedures, software, and IT infrastructure that are subject to industry-specific or widely applicable regulations such as PCI DSS, HIPAA, GLBA, and GDPR. Compliance assessment services encompass:
- Examination of security and quality assurance policies and procedures
- Assessing employees' understanding of relevant standards and regulations.
- Perform security testing on software and IT networks.
- Provide remediation guidance and practical assistance to rectify any identified gaps.
A comprehensive evaluation of software security controls involves examining software protection measures alongside the assessment of information security policies and the cyber resilience of employees.
Here are some popular techniques employed in the process:
- Software Application Security Testing (SAST)
It falls under the category of white box testing, where the security testers are familiar with how the code was built, focusing on testing the application’s actual code. It Identifies common coding vulnerabilities like SQL injection, cross-site scripting, and insecure direct object references.
Can be automated and integrated into the development process, making it a good choice for early detection of vulnerabilities.
- Dynamic Application Security Testing (DAST)
DAST operates as a black-box security testing in which testers are uninformed of the app’s underlying architecture. It’s designed to detect vulnerabilities while the app is in runtime. It can identify vulnerabilities that SAST might miss, such as logic flaws and configuration errors. While it requires more manual effort than SAST, the testing type can be more effective at finding critical vulnerabilities.
- Interactive Application Security Testing (IAST)
IAST combines elements of both SAST and DAST to assess the potential exploitation of known vulnerabilities (SAST) within a live application environment (DAST). These tools leverage knowledge of data and application flow to visualize complex attack scenarios. The resulting test cases are then used iteratively to generate additional test cases, building upon DAST results.
In high-paced DevOps environments, IAST tools demonstrate enhanced efficiency and reduced false positives compared to relying solely on DAST or SAST. The real-time feedback provided during testing equips developers with the intelligence and context necessary to promptly recognize and address vulnerabilities as they emerge. This facilitates quicker remediation, leading to a reduction in the overall time and effort required to rectify security issues within the application, thereby minimizing the likelihood of application-related data or security breaches.
When deciding on a mobile app security testing tool, it’s vital to consider a variety of capabilities to guarantee thorough testing and safeguard your banking mobile apps. Here are some crucial features to consider:
- Automation & CI/CD integration
Search for a tool that seamlessly integrates into your CI/CD pipeline with common development tools, including integrated development environments (IDEs), build systems, and continuous integration/continuous deployment (CI/CD) pipelines to enhance the efficiency of the development and testing workflow.
- Customization and configuration
The ability to customize and configure not only enhances flexibility but also enables a more precise alignment of the tool with the specific intricacies of your organization's security landscape, fostering a tailored and robust security framework.
The tool should remain adept at handling increased workloads, data volumes, and user interactions, all while maintaining optimal performance levels
- Customer support and community
An active user community adds immense value by fostering the sharing of knowledge, best practices, and user-generated scripts or plugins that enrich the functionality of the tool. Moreover, the presence of responsive and knowledgeable customer support from the tool's provider is crucial for ensuring a positive user experience.
- Detailed reporting
The tool is expected to generate a concise and actionable report detailing identified vulnerabilities, encompassing crucial information on the severity of each issue, potential impact, and recommendations for effective remediation.
