Application Security Assessment is designed to identify and assess threats to the organization through bespoke, proprietary applications or systems. These applications may provide interactive access to potentially sensitive materials. It is vital that they be assessed to
ensure that

the application doesn't expose the underlying servers and software to attack(s), and

a malicious user cannot access, modify or destroy data or services within the system.
Even in a well-deployed and secured infrastructure, a weak application can expose the organization's information assets to unacceptable risk. Visit the following links to get a better insight of our application security related research activities:
NII Approach to Application Security Assessments
NII uses a number of software-testing techniques (including black-box testing, fault injection, and behavior monitoring), as well as real-world situations to test each application. The NII methodology is as described below:
High Level Design Audit
High Level Design Audit identifies and analyzes:

Flow of information throughout the application environment

Sensitive data in different sections of the organization

Threats to the sensitive information in question
Source Code Audit
In this step the code is reviewed for vulnerabilities and threats that belong to these categories:

Cryptography

Authentication

Session Management

Data Validation

Exception Management

Authorization

Auditing and Logging
Black Box Testing

Testing Communication Behavior

Identifying Fault Injection Points

Identifying Client-side behavior of the application

Testing interactions with third-party applications

File Interpretation

Cryptanalysis
BenefitsApplication Security Assessments help

Secure the flow of information through the application

Implement secure coding practices, remove logical, formatting flaws in the application code

Embedding security right from the design to the execution stage

Recognize the existing vulnerabilities and the extent of current and potential damages posed by the application

Harden technologies keeping in mind the involvement of people which is a key criterion for any strategy to succeed
Above all, the strategies recommended by NII at the end of the exercise will put appropriate application controls in place.
