CYBERSECURITY TESTING

Code Review &
Assessment Services.

Find security weaknesses in the code before they become exploitable defects. Some of the most serious security flaws are visible only when source code, data flows, and business rules are examined together.

SOURCE-ASSISTED ASSURANCE

A source-assisted review of software implementation.

Code Review and Assessment examines how security controls are implemented, how untrusted data moves through the software, and whether sensitive operations can be reached in unintended ways. Manual review is supported by targeted static analysis, secrets detection, and dependency checks.

Full Security Baseline Review

Complete source-assisted security evaluation of an agreed application, repository, or architecture baseline prior to production release or M&A acquisition.

Focused High-Risk Module Review

Targeted assessment focusing specifically on critical software modules such as identity providers, payment gateways, cryptography, or administrative features.

Auth & Crypto Modules File Processing High ROI Triage

Diff-Based & Release Review

Efficient review focused on pull requests, release branches, patches, or major feature changes to ensure new commits do not introduce regressions.

SAST Triage & DevSecOps Integration

Independent expert validation of existing automated SAST, secrets-scanning, and dependency findings, filtering out noise and integrating security gates into CI/CD.

When This Service Is Useful

Applications approaching release, procurement, acquisition or assurance review.
Changes to identity, payments, file handling, cryptography or sensitive-data processing.
Teams requiring expert validation and prioritisation of automated static-analysis findings.
Legacy or inherited codebases with unclear security assumptions or technical debt.
Organisations introducing secure-development gates or repeatable review practices into CI/CD.
Validating compliance with NCSC secure development guidelines and OWASP ASVS.

TECHNICAL SCOPE

What we test.

We trace untrusted data flows, review privilege logic, inspect cryptographic implementation, and audit third-party dependencies.

DATA FLOW

Architecture & Trust

Entry points, privilege boundaries, sensitive assets, and untrusted data movement through services, storage, and integrations.

IDENTITY

Auth & Session Handling

Credential handling, recovery mechanisms, session tokens, session lifecycle, identity-provider integration, and privileged roles.

AUTHZ

Authorisation & Isolation

Object, function, role, and property-level checks, administrative paths, ownership validation, and multi-tenant separation.

INJECTION

Input & Output Security

Validation, encoding, parameterisation, file/path handling, XML parsers, deserialisation, and command/SQL interactions.

SECRETS

Data, Secrets & Crypto

Hard-coded API keys/secrets, key management, encryption algorithms, randomness, hashing, personal-data exposure, and logging.

LOGIC

Business Logic & State

Workflow bypasses, replay conditions, race conditions, state transitions, transaction integrity, and resource consumption limits.

DEPS

Dependencies & Build

Dependency manifests, unsafe third-party packages, build scripts, feature flags, environment handling, and debug code.

ERRORS

Error Handling & Memory

Exception paths, fail-open behavior, information leakage, unsafe memory operations, concurrency, and framework pitfalls.

METHODOLOGY

How the engagement works.

A 6-stage testing framework aligned with NCSC secure-development guidance, UK Software Security Code of Practice, OWASP ASVS 5.0.0, and NIST SSDF 1.1.

STAGE 01

Define Review Baseline

Agree repositories, branch or commit ID, technologies, components, depth, exclusions, and review model.

STAGE 02

Understand System

Review architecture diagrams, threat models, trust boundaries, sensitive functions, and expected security controls.

STAGE 03

Run Targeted Analysis

Execute static analysis (SAST), secrets-detection, or dependency checks, then de-duplicate and triage output.

STAGE 04

Trace Critical Code Paths

Follow input, identity, permissions, sensitive data, and state changes manually through realistic misuse cases.

STAGE 05

Validate & Prioritise

Confirm reachability and business impact, identify related instances across the codebase, and prioritize root causes.

STAGE 06

Report & Walkthrough

Deliver developer-ready evidence, discuss remediation patterns with engineers, and re-assess corrected code.

ENGAGEMENT DETAILS

Requirements & Deliverables.

Clear input requirements and developer-ready remediation guidance delivered upon project completion.

What We Need From You

Read-only repository access or an approved code snapshot (exact branch and commit).
Architecture, data-flow diagrams, threat models, and security requirements where available.
Build instructions, dependency manifests, configuration files, and deployment details.
A technical contact who can explain workflows, trust decisions, and sensitive logic.
Existing SAST, secrets, dependency, or security assessment findings.

What You Receive

Executive summary highlighting software-security risks and business priorities.
Recorded repositories, commit hash, components, tools, assumptions, and limitations.
Risk-rated findings with affected code paths, developer-ready evidence, and CWE references.
Root-cause analysis, practical remediation patterns, and an engineer walkthrough.
Verification status for agreed corrected code patches.

Important Scope & Safety Note

Source code is commercially sensitive and may contain credentials or personal data. Access, storage, approved locations, retention, and deletion arrangements are agreed before transfer. We use least-privilege, read-only access wherever possible and do not modify a repository or production system without explicit approval. Findings apply to the reviewed version and scope; code outside the baseline, generated artefacts, runtime configuration and external services may require separate testing.

WHY WORLD COMPUTING

Evidence-led code security.

Developer-Ready Reporting

Clear reporting designed for developers, engineering leads, and technical decision-makers.

Human-Driven Context

Manual review goes beyond automated scanner output to uncover complex business logic flaws.

Practical Remediation

Findings prioritized by actual exploitability with practical code remediation patterns.

Engineering Collaboration

A collaborative approach that supports development teams throughout the assessment and fix cycle.

COMMON QUESTIONS

Code Review FAQ

How is a secure code review different from a penetration test?

A code review examines implementation and data flows from inside the software, while a penetration test primarily interacts with a running system. They find overlapping but different classes of weakness and provide stronger assurance when used together for high-risk applications.

Is this just an automated SAST scan?

No. Tools support coverage but can miss business logic and context, while also producing false positives. The assessment uses expert manual analysis to validate tool output, trace security decisions and identify weaknesses that pattern matching alone may not detect.

Which programming languages and frameworks can be reviewed?

Scope depends on the technologies and the depth required. We confirm suitable reviewer expertise and tooling during scoping; specialist or unusual languages may require an adjusted approach or additional subject-matter support.

Do you need access to the complete repository?

Not always. A focused or diff-based review can assess selected components, but omitted shared libraries, generated code, configuration or surrounding services may limit the conclusions. Dependencies and trust boundaries must be clear enough to interpret the selected code correctly.

Will you change our code or commit fixes?

The standard service is an independent assessment, so repository access is normally read-only. We provide clear remediation guidance and can review proposed fixes. Any hands-on change or development work would require a separate, explicitly authorised agreement.

When should code review be repeated?

Use review before major releases and after material changes to security-critical functions. Regular peer review and automated checks should operate continuously, with independent focused review scheduled according to risk, change volume and assurance needs.
