What is a Source Code Security Review?
A source code review can identify security flaws in an application, such as a web application or a mobile application. By performing a source code review, certified security consultants assess whether secure coding best practices have been applied and identify any vulnerable components.
Unlike external black-box penetration testing alone, examining application code directly allows security consultants to trace data flows, evaluate authentication mechanisms, and uncover complex architectural logic flaws that automated scanners frequently miss. Implementing code-level security assessments within the Software Development Life Cycle (SDLC) reduces remediation costs and ensures software resilience.
Key Vulnerabilities Identified
Assessments combine automated Static Application Security Testing (SAST) tools with rigorous manual code inspection. Core focus areas include.
Injection Flaws and Input Handling
Detecting SQL injection, OS Command injection, and Cross-Site Scripting (XSS) weaknesses caused by improper input sanitisation and parameterisation.
Hardcoded Secrets and API Keys
Uncovering embedded credentials, API tokens, cryptographic keys, and internal connection strings within source repositories.
Insecure Dependencies and Component Flaws
Identifying outdated third-party libraries, open-source frameworks, and packages containing known CVEs and security flaws.
Broken Authentication and Authorisation Logic
Spotting flawed access control implementations, improper session handling, and privilege escalation vulnerabilities directly within business logic.
Insecure Cryptographic Practices
Finding weak encryption algorithms, hardcoded seeds, improper key storage, and insecure random number generation.
A CREST-Accredited Methodology
Every development environment utilises unique frameworks, design patterns, and programming languages. Source code reviews are customised to support major development languages, including C#, Java, Python, JavaScript/TypeScript, PHP, Go, Swift, and Kotlin.
As a CREST-accredited service provider, Cyber Security Specialists guarantees that testing is delivered by highly skilled professionals holding recognised technical certifications such as OSCP and CREST. All assessments follow industry-recognised standards, including OWASP Secure Coding Practices, OWASP ASVS, and PCI-DSS requirements.
Comprehensive Reporting and Remediation
After the source code review, we deliver a detailed, actionable report to development and IT security teams. This documentation classifies the risks to the overall cybersecurity posture, prioritises vulnerabilities to address, and provides clear technical remediation guidance, including code-level fixes and patches. Development teams receive precise technical guidance to remediate flaws before release.
Secure Software Applications Today
Source code reviews help organisations identify and fix vulnerabilities before attackers can exploit them, reducing risk and protecting proprietary applications.
