Web Application Pen Testing

A Web application pen testing aims to identify security vulnerabilities resulting from insecure coding practices or underlying platform weaknesses of software or a website.

Website security testing is named differently, often based on the name of applications, platforms or popular software in use. Web application security assessments is a simulation of web based attacks to attempt gain access to underlying sensitive data just like an unauthorised user would in the event of an attack.

There is a history of WAF or corporate firewall bypasses in the past, and it is then the application code that should come up to the task. Ensuring secure coding practices is the comprehensive way to secure web applications.

Cyphere, web applications services can be commissioned to assess in-house developed applications, off-the-shelf or cloud service provider applications. For example:

  • WordPress penetration test or similar CMS (Content Management System) application pen test
  • OWASP Web Penetration Testing
  • eCommerce businesses requiring Magentopenetration testing or WordPress penetration testing
  • More complex platforms such as Banking login product security, Gambling platforms web security, or eCommerce security

What type of web penetration testing service does your business need?

application penetration testing

The following questions help decide why and what type of web application penetration test service a business requires to improve their web application’s security posture.

  1. Could your website compromise lead to a data breach? 
  2. Could your platform or web application be exploited to access the underlying network? 
  3. Are your development teams aware of web application security risks?
  4. How is your CMS or off-the-shelf CMS security?
  5. Whether any processing or storing of payment details is performed securely?
  6. Are your web applications holding static content only, with a shared database instance? 
  7. Whether any PII (Personally Identifiable Information) is stored in the shared database instance at the backend. 

Most importantly, have you independently validated your security controls irrespective of your product, platform or network provider?we

Benefits of Web Application Pen Testing

No cancellations or retest charges - no fuss, promise!

Types of Application Pen Testing

Web application penetration Testing

A web application security testing forms the basis of any business trading on the Internet securely. Without security in mind, applications are a treat for online fraudsters to target genuine unsuspecting users.​

Secure code review

Secure Code review is the process of manually reviewing the source code that would highlight issues missed during a black box pentest. This review helps to detect the inconsistencies overlooked during all other web app security assessments.

API security testing

APIs are the backbone of architecture backing the digitally connected world. Web services security testing for public and private RETS APIs used by Mobile, Web Applications and Thick clients.

Thick client application pentesting

Thick or compiled applications are popular in an enterprise for their internal operations. Legacy thick client applications could have inherent problems waiting to be discovered or rather exploited.​

Threat modelling

Threat modelling service deals with helping customers to identify, communicate, and understand threats and mitigations within the context of protecting most valuable data. ​

Database security review

Data breaches are directly related to extracting data from databases. Validation of security controls around data storage through website penetration testing helps organisations protect the stored data. This includes both cloud and traditional database storage systems.

Web Application Vulnerabilities

Secure hardening vulnerabilities such as OS or web server software patching, information disclosures, directory listing, TLS/SSL encryption weaknesses and network footprint are most common in web apps security testing.

User input submitted to the application is thoroughly tested in a web app penetration test to identify any opportunities for malicious input. Common vulnerabilities such as Cross-Site Scripting (XSS), HTML, JS, SQL Injection, XXE, Cross site request forgery (CSRF), server side request forgery (SSRF) fall under this category.

Business logic flaws are often customers’ ‘bang for the buck’ as inexperienced teams or automated scanners often ignore these flaws in a web application pentesting. These include events, actions or sequence of steps often missed by developers.

Whether it is possible to access unauthorised functionality and/or data, such as viewing, modifying other user accounts or changing access rights. It may include specific issues to be considered during internal pen testing to discover the most vulnerable route for inside attackers.

We check against the configuration and use of encryption methods used for data at rest and transit. This ensures data is safe against tampering and eavesdropping web application attacks.

Authentication vulnerabilities are one of the most critical and important attack vectors. This area includes multiple website penetration test cases i.e. transmission channels, nature of input, insecure configurations, weak credentials & bypass attempts.

Whether application enforces strict password controls via user account policies and backend password storage in the database. Database storage mechanisms are reviewed to assess encryption algorithms in use.

Session management is the bedrock of authentication domain when it comes to applications. This includes checking for session state, predictability, token tampering, manipulation, session hijacking tests.

Frequently Asked Questions about Web App Penetration Testing

A technical exercise aimed at simulating an internet based threat actor or an insider to identify and safely remove web application exploits and weaknesses in the applications.

Based on the functionality and requirements, web application penetration testing offerings include website pen tests, API web app security testing, source code review, database security to a multi-tiered assessment involving the entire tech stack. Specific threat scenarios around data theft or utilising social engineering attacks around malicious employee attacks directly relate to the testing cases such as privilege escalation, authenticated user testing.

Our testing methodology involves checks included in OWASP Top 10, OWASP API Security Top 10, SANS Top 20 Critical Controls and CIS, NIST 800-115. Any specific requirements should be discussed during scoping exercise to reflect this in the deliverables. See our pen test blog post for detailed information.

Our teams utilize a mix of open source and commercial software in addition to a number of custom scripts and utilities. We are happy to share specific list based on the engagement.

In order to maximise the investments in independent testing, one should wait till the assessment is over. This offers comprehensive view of the attack surface as well as coverage and depth of issues identified.

Any development activities that must continue should be discussed with our team to mutually agree on minimising impact on web security testing. Similar approach is considered when using Web Application Firewall (WAF) to cover unauthenticated and authenticated vulnerability detection scenarios.

Communication plays an important role during security assessments. We always prompt customers to inform us about fragile components during project initiation meetings. Low level attacks, Denial of Service attacks are explicitly deemed out of scope for all assessments.

A custom written report is prepared based on the findings after complete web application penetration testing. This report serves both technical and non-technical audiences with specific sections dedicated to strategic and tactical recommendations, raw/supplemental data, proof of concepts and risk details such as impact, likelihood and risk scorings.

This is followed by mitigation advice along with related references to help customer teams with remediation.

Website pen test remediation is sometimes a complex process due to the specialist security skill-set needed for IT teams. As part of our aftercare support, we provide help in preparing remediation plan to all our customers.

Optionally, we provide remediation consultancy to ensure all agreed findings are mitigated in line with best security practices.
