In fast-paced coding environments, where critical deadlines demand that code be written, tested and deployed within a short time period, unsafe coding practices are very prone to creep-in, which may lead to errors from the security aspect. This code is where security defects originate, which can lead to threats and vulnerabilities in an application and its functionalities. Code reviews identify programming flaws that can make applications vulnerable to attack and exploitation, for mitigating risks and eliminating architectural flaws.
Secure code review is the process of auditing the code of an application on a line by line basis for its security quality. This ensures that the application is developed properly so that the application defends itself in its own environment.
A Code Review discovers implementation-level vulnerabilities introduced during coding and recommends remediation for those coding errors. It provides an analysis of an existing codebase and locates code constructs that lead to security vulnerabilities. A security code review is designed to highlight potential security vulnerabilities within the application based upon a defined application threat-model. These services provide a very granular level of review on the actual application source code in order to ensure that best practices of secure coding are in place, thus providing the highest level of scrutiny.
QSEAP METHODLOGY I
Qseap is well versed in secure code reviews for nearly all programming languages in use today, including: Java, .NET, C / C++, C#, ASP, Visual Basic, Visual Basic.NET, ABAP, Ruby, PHP, Perl, Python, TCL, AJAX and assembly language.
We perform source code audits for our clients with an established hybrid methodology by combining scripts, custom tools, static analysis tools, automated tools and manual code review to uncover the highest number of flaws possible.
During code reviews, we look for the following flaws in the code:
Application Architecture Security
Input Validation Filters
Session based attacks
End user information disclosure attacks, between users
Cross Site request attacks
Cross domain redirection attacks
Exception management, Error reporting and information leakage
Poor enforcement of authentication, authorization and access control
Weak cryptographic algorithms and implementation
Insecure database access
Inadequate protection of data
Missing or weak security boundaries
QSEAP METHODLOGY II
Exploitable gaps in business logic
Poor resource management
Insufficient audit records
Vulnerability to well-known attacks
Miscellaneous code quality and consistency issues
Non-compliance with organizational code development policies
Undocumented public interfaces
Code access security
Unsafe and unmanaged code
Threading, and many more
Qseap works closely with the application owners during the process to ensure thorough communication and understanding of application scope, functionality and intended design. The outcome of a Code Review is a detailed report describing each code-security issue broken down by the vulnerability itself, analysis of the severity of the finding and recommended mitigations with code samples to resolve the issues for improved security in ways that are aligned with industry best practices. This allows the development team to understand the problem areas of their code in a better way and prevent mistakes in the future.
What is different?
Qseap employs a well-established hybrid methodology of using tools and manual review at the same time. A fully manual process may consume a long time, and a fully automated process may miss out the vulnerabilities. Qseap develops a threat-model for each review which helps in minimizing the time to identify all possible risks.
Qseap's Secure code review induces the following significant paybacks to the customers' projects:
Eliminates security-defects in the application before release
Protection from vulnerabilities and attacks
Lesser updates and patches
Saves critical time and code rewrite costs
Benefit over the competitor by having a reputation of releasing safer-software
Secure Code Review is the sure-shot silver-bullet to identify software vulnerabilities. Improper design or implementation in SDLC Process life cycle while developing software, results in vulnerabilities and flaws in the code. Organizations today, face the biggest security concerns from software insecurity.
