Designing the business cordial to the Enduser

Business logic vulnerabilities are often defined as the flaws in the design and implementation of an application that allows the threat actors to exploit the applications. These flaws generally occur as the developers fail to anticipate the behaviour of the end-user using the application. 


Business logic is intended to enforce the rules and constraints defined at the time of designing the application, preventing the users from doing anything that may negatively impact the business. These logic-based vulnerabilities can be extremely diverse depending on the application and its functionalities. 


Bugs or flaws in the logic can allow the attackers to outwit these rules. They might exploit by making arbitrary changes in the user data or may pass unexpected values to the server-side of the application forcing it to do unexpected tasks. 


The impact of business logic vulnerabilities can be huge. These flaws in logic should be fixed even if the developers can't figure out, how these can be exploited. 


Business logic testing or application logic testing, for testing the flaws in a multi-functional application requires unconventional methods. It is not possible to test these vulnerabilities through automated tools, hence it's done by a person.

Why is Business logic testing important for your business?

A logic vulnerability is not a flaw in the coding framework, but the way it is exploited to do something unexpected. developers often focus on making the application user-friendly but are unaware of ways hackers can misuse certain functionalities from the server side as in the case of authorization issues, denial of service etc. 


Using both Dynamic Application Security Testing (DAST) and Static Application Security Testing (SAST) the application security can be improved on overall compliance and risk management. Tools included in the manual vulnerabilities finding are OWASP Top 10, CWE Top 25 issues, Cross-Site Scripting (XSS), SQL injection, Fingerprinting, Content Spoofing, Cross-Site Request Forgery (CSRF), URL redirector abuse, Brute Force, etc. 


According to the experts, 20% of the vulnerabilities are detected during Business Logic Testing or Application security testing, out of which 80% are of high to medium rating.

These are the kind of errors that allow attackers to manipulate the business logic of an application. These errors can't be located automatically, hence can be located by the one who understands the business.
The impact can be fairly trivial. Any unintended behaviour can potentially lead to high-severity attacks if an attacker can manipulate the application in the right way. Even if you don't understand how any logic can be exploited, there are chances that someone else can.
Business logic testing involves evaluating the functional aspects of a system, focusing on its underlying rules and processes. It ensures that the software behaves correctly and meets business requirements. It's crucial for organizations to ensure that their systems operate accurately and efficiently to support business operations and deliver value to customers.
Unlike traditional testing methods that focus on individual components or modules, business logic testing examines the core logic that drives system behavior. It evaluates how well the software aligns with business rules and processes, ensuring that it meets business objectives effectively.
The objectives include verifying the accuracy and consistency of business rules, validating system behavior against expected outcomes, identifying and resolving logic errors or inconsistencies, and ensuring compliance with regulatory requirements.
Examples include pricing errors in e-commerce platforms, incorrect calculations in financial systems, eligibility flaws in insurance applications, and faulty decision-making logic in workflow management systems.
We collaborate closely with stakeholders to understand business requirements and identify critical scenarios based on factors such as business impact, frequency of use, and regulatory compliance. We prioritize testing efforts to focus on high-risk areas and critical functionalities.
We employ a variety of tools and methodologies, including test automation frameworks, business rule management systems, domain-specific testing techniques, and agile testing practices tailored to business logic validation.
The frequency of testing depends on factors such as the complexity of the system, the rate of change in business rules, regulatory requirements, and risk tolerance. Generally, it's recommended to conduct business logic testing as part of regular software maintenance and whenever significant changes are made to the system.
We tailor our testing approach to align with industry-specific regulations and compliance standards by conducting thorough requirements analysis, collaborating with compliance experts, and implementing appropriate testing techniques and controls.
Yes, we understand that every organization has unique business processes and requirements. We customize our testing approach to address your specific needs, incorporating industry best practices and leveraging our expertise to deliver tailored solutions.
