Application Security

Web application testing that goes beyond automated scanning.

TruSec manually evaluates user roles, workflows, business logic, sessions, inputs, and data access to identify weaknesses that scanners and generic checklists routinely miss.

Service Overview

Test the application as a system of users, data, and business processes.

Modern application risk is often created by how functions interact—not by a single obvious vulnerability. A valid user may be able to access another customer’s records, a low-privileged role may reach administrative functions, or a normal workflow may be manipulated to bypass an intended business rule.

TruSec performs black-box, gray-box, or authenticated testing based on the objectives of the engagement. The assessment can include public and authenticated interfaces, administrative functions, file handling, integrations, client-side behavior, and role-specific workflows.

Assessment Coverage

Manual coverage across the application attack surface.

Testing is adapted to the application architecture, user roles, data sensitivity, and business workflows.

Authentication

Login, account recovery, multifactor workflows, password controls, enumeration, lockout behavior, and alternate authentication paths.

Authorization

Horizontal and vertical access control, insecure direct object references, role boundaries, administrative functions, and tenant isolation.

Session Security

Cookie protections, token handling, session lifecycle, logout behavior, fixation, replay, timeout, and concurrent session controls.

Input and Data Handling

Injection, cross-site scripting, file upload, deserialization, path handling, server-side requests, and unsafe data processing.

Business Logic

Workflow bypass, transaction manipulation, sequence abuse, pricing or quantity logic, approval processes, and automation resistance.

Information Exposure

Sensitive data leakage, verbose errors, source maps, client-side secrets, predictable identifiers, metadata, and insecure caching.

How the Engagement Works

Testing organized around risk and repeatable evidence.

Understand the application

Confirm architecture, roles, workflows, sensitive functions, environments, and testing constraints.

Map the attack surface

Enumerate accessible functions, parameters, objects, endpoints, client-side behavior, and trust boundaries.

Test and validate

Manually test security controls and safely demonstrate the impact of meaningful weaknesses.

Report and support fixes

Provide endpoint-specific evidence, remediation guidance, executive context, and optional retesting.

Deliverables

Findings that developers can reproduce and fix.

Each meaningful issue is documented with enough context for leadership to understand the risk and for technical teams to correct it.

  • Executive summary and application risk posture
  • Tested roles, functions, workflows, and environments
  • Risk-rated findings with affected URLs or functions
  • Steps to reproduce and supporting evidence
  • Technical and business impact
  • Developer-focused remediation guidance
  • OWASP category and control mapping where useful
  • Retest results for corrected findings

Findings are separated by affected function or attack path so the report remains useful during remediation and verification.

Common Questions

Web application testing questions

Do you need application credentials?

Authenticated testing is strongly recommended when the application has user roles or protected workflows. Testing can include multiple accounts to evaluate horizontal and vertical authorization boundaries.

Is this only an OWASP Top 10 test?

No. OWASP provides useful coverage guidance, but the assessment also evaluates application-specific business logic, workflows, trust boundaries, and abuse cases.

Can testing be performed against production?

Yes, when appropriate safeguards and rules of engagement are defined. A staging environment may be preferred for destructive functions or unstable features, but it should accurately represent production.

Will the report include remediation guidance?

Yes. Findings include practical corrective recommendations and enough evidence for developers or platform teams to reproduce and validate the issue.
