Web Applications
Authentication, authorization, session handling, input processing, exposed functionality, and common application-security weaknesses.
Authorized application security testing
Find weaknesses before they become incidents.
Authorized penetration testing for websites, web applications, and APIs — designed to identify real, reproducible security weaknesses within an agreed scope.
Scoped. Authorized. Evidence-driven.
Why penetration testing?
Security problems are easier to fix before they become incidents.
A penetration test examines an application from an attacker’s perspective within an agreed and authorized scope.
The objective is not simply to generate scanner output. Potential findings are investigated, validated where appropriate, prioritized by practical risk, and documented with enough context to help support remediation decisions.
Assessment coverage
What can be assessed?
APIs
Endpoint authorization, object-level access control, authentication, excessive data exposure, parameter handling, and other API security concerns.
Access Control
Review of user roles, permissions, object access, and workflows where one user may be able to access functionality or information intended for another.
Business Logic
Manual investigation of workflows where technically valid requests may create unintended or insecure outcomes.
Configuration & Exposure
Security headers, exposed resources, deployment configuration, information disclosure, and other externally visible security weaknesses.
Authentication & Session Security
Login flows, account recovery, session handling, authentication boundaries, and related security controls.
The areas covered in an assessment depend on the agreed engagement scope. Not every assessment includes every category.
Approach
A deliberate assessment process.
- 01
Scope & Authorization
Define the permitted systems, testing boundaries, exclusions, objectives, and engagement conditions before testing begins.
- 02
Reconnaissance & Review
Understand the authorized attack surface and application behavior using appropriate non-destructive techniques.
- 03
Manual Validation
Investigate potential weaknesses and manually verify findings wherever practical to reduce false positives and understand impact.
- 04
Evidence & Reporting
Document confirmed findings with affected components, reproduction information, evidence, risk context, and remediation guidance.
- 05
Remediation Follow-Up
Where included in the engagement, discuss fixes or perform a focused retest after remediation.
Assessment principles
Why Jonaski Web Development?
Manual Validation
Automated tooling may assist an assessment, but potential findings are manually reviewed wherever practical before being presented as confirmed vulnerabilities.
Authorization First
Testing is performed only against systems the client owns or is explicitly authorized to have tested.
Web & API Focus
Assessments are designed around modern websites, web applications, APIs, authentication flows, access control, and related application-security concerns.
Evidence-Driven Findings
Confirmed issues are supported by clear reproduction information and relevant technical evidence.
Risk-Based Reporting
Findings are organized around practical security impact so remediation effort can be focused appropriately.
Remediation Guidance
Reports include practical mitigation or remediation guidance where appropriate.
