Do You Need a Thick Client Pentesting?

What is Thick Client Pen Testing?

Thick client pentesting is an amalgamation of information gathering and Securing endpoints from various cyberattacks. It scans vulnerabilities for client-side, server-side, and network-side attacks. It is not only about automated scanning. It involves a comprehensive methodology and a customized test environment.

Do You Need a Thick Client Pentesting?

A lot of businesses have been using thick client applications for an exceptionally long time. Thick client pentesting is required to safeguard the security of organizations using these applications. It uses proprietary protocols for communication and assessment scanning.

Thick client applications adopt a hybrid infrastructure for operations. This makes them an easy target for attackers. Thick client pentesting can help you find the vulnerable points. You can then take remediation steps to ensure protection against severe threats.

There are two types of thick client applications that need pentesting:
1. Two-tier thick client application
In this type of application, there is only a computer and server. The installation is on the client-side. These applications directly communicate with the database. Desktop Games, Music players, and Text editors are the major examples of two-tier thick client applications.

2. Three-tier thick client application
In these applications, a layer of the application server is added to the communication. The client needs to access the database through the application server. A few examples of the three-tier thick client application are Firefox, Chrome, Burp Suite, and Zap Proxy.

Testing Procedure for Thick Client Applications

The thick client applications are quite different than the conventional applications. You need a thorough and comprehensive approach to penetration tests. Following are the steps to take during the thick client application security testing:

• Analyzing the tools and techniques used on both client and the server-side.
• Discovering all the characteristics and functionalities of the application.
• Understanding all the endpoints
• Dissection of all the security measures present in the application
• Scanning the vulnerabilities, all hidden and visible

Types of thick client application security testing

Black-Box Testing
Testing the application without having any prior knowledge of its configurations. Testers test all the functionalities of the application without having access to the design/application, and backend processes.
Grey-Box Testing
In Grey-Box Testing the team has access to only infrastructure basics and working knowledge of the application before testing. This knowledge is about the data flow within the application and API documentation.

Common Thick Client Vulnerabilities

The outcomes of thick client application security testing are the common vulnerabilities present in the application. The following are the key vulnerabilities you will get to see after thick client pentesting:

• Information Leak
• Tampering and Loss of Data
• Weak Authentication Protocol
• Error in Configuration and Handling
• Compromised Authorization
