Source Code Review & Analysis
Source Code Review is a critical part of the software development lifecycle, where security experts analyze an application’s source code to identify vulnerabilities, coding flaws, and potential security weaknesses. By thoroughly reviewing the source code, we ensure that security is embedded directly into the application, reducing the likelihood of exploits and breaches. A proactive source code review helps organizations build secure applications from the ground up, preventing risks that may arise later in the deployment phase.
Why is Source Code Review Critical?
While automated security tools can detect known vulnerabilities, source code review offers a more comprehensive, manual approach to identifying flaws in the application’s logic, structure, and implementation. Many vulnerabilities, such as business logic errors or complex security flaws, can only be detected through a manual inspection of the source code. Ensuring that your source code is secure not only minimizes the risk of attacks but also helps maintain compliance with industry standards and regulations.
Standards We Follow
Our source code review process adheres to industry best practices and security standards, ensuring a thorough and reliable analysis:
- OWASP Secure Coding Guidelines: We follow the OWASP (Open Web Application Security Project) guidelines, which provide comprehensive standards for writing secure code and identifying common coding vulnerabilities.
- SANS CWE/SANS Top 25: We focus on the most common and critical software vulnerabilities, as defined by the SANS Institute’s Top 25 Most Dangerous Software Errors.
- ISO/IEC 27034: This standard provides guidelines for secure coding practices, ensuring that applications are resilient against security threats.
- NIST SP 800-53: We integrate NIST’s security controls into our review process to align with the highest standards of application security.
Vulnerabilities We Find
During a thorough source code review, we focus on identifying and mitigating a wide range of vulnerabilities that could lead to security risks:
Authentication and Authorization Issues
- Weak Authentication Mechanisms: Hardcoded passwords, unprotected session tokens, or poor implementation of multifactor authentication.
- Privilege Escalation: Code flaws that allow unauthorized users to gain elevated privileges or perform actions beyond their assigned permissions.
Injection Attacks
- SQL Injection: Improper input validation or parameterization of SQL queries, allowing attackers to manipulate the database.
- Command Injection: Insecure use of system commands, where user inputs can be executed as system commands on the server.
- XML Injection: Vulnerabilities in XML parsing, allowing attackers to manipulate XML data or execute malicious payloads.
Insecure Data Storage
- Plaintext Data: Storing sensitive data, such as passwords or API keys, in plaintext or improperly encrypted.
- Insecure Cryptographic Practices: Using weak or outdated encryption algorithms, or poor key management.
Cross-Site Scripting (XSS)
- Stored XSS: The application fails to properly sanitize user inputs that are stored and later rendered back to the user, allowing attackers to inject malicious scripts.
- Reflected XSS: Inputs that are reflected back to the user without proper encoding or validation, allowing malicious scripts to be executed.
Insecure Communications
- Unencrypted Data Transmission: Sensitive data being transmitted without encryption, exposing it to interception via Man-in-the-Middle (MitM) attacks.
- Improper Handling of API Calls: Failing to authenticate or properly validate API requests, leading to potential data exposure or unauthorized access.
Business Logic Flaws
- Broken Logic: Misimplementation of application workflows or business rules that could allow attackers to bypass key security measures, such as access controls or validation processes.
- Race Conditions: Exploitable timing issues that could allow attackers to manipulate the application’s behavior or state.
Insecure Dependencies
- Outdated Libraries: Use of old or unpatched libraries that have known vulnerabilities.
- Insecure API Integrations: Poorly secured third-party APIs that could be exploited by attackers to gain unauthorized access or cause disruption.
Deliverables: What You Receive After Testing
After the source code review, we provide a Security Assessment Report that includes:
- Detailed Findings: A thorough analysis of the vulnerabilities discovered in the source code, categorized by severity and potential impact.
- Exploitability: A description of whether and how these vulnerabilities could be exploited in a real-world attack.
- Remediation Recommendations: Clear, actionable advice for developers on how to fix the identified issues, including code changes and best practices.
- Security Best Practices: General recommendations on improving coding practices, securing libraries, and enhancing the overall security of the development lifecycle.
- Follow-Up Consultation: A follow-up consultation to help clarify the report and guide the development team through the remediation process.
