Title: Thick Client Penetration Testing Modern Approaches and Techniques (1)
1Thick Client Penetration Testing Modern
Approaches and Techniques
What Is Thick Client Penetration Testing ? A
client program that can offer rich functionality
without relying on the server in a network
is referred to as a thick client, also known as
a fat client. The majority of thick client
operations can be carried out without an active
server connection. While they do occasionally
need to connect to a network on the central
server, they
2- can operate independently and may contain
locally stored resources. - On the other hand, a thin client is a client
program or computer that requires a connection
to the server in order to work. Thin clients rely
heavily on server access each time they need to
analyze or validate input data because they
perform as little processing on their own as is
feasible. - Why do thick client applications need testing?
- For internal operations, thick client
applications are crucial. They are frequently
used to interact with private data, such as
financial and health records and they provide a
significant danger to a business, particularly
if they are legacy applications. - Thick clients function differently, and each has
advantages and disadvantages of their own. The
security that thin clients offer over thick
clients is one of their main advantages. The
following are some of the main security issues
with thick clients - Sensitive data disclosure.
3- Denial of Service (DoS).
- Improper access control.
- Improper session management.
- Reverse engineering.
- Injection attacks.
- Variable and response manipulation.
- Improper error handling.
- Insecure storage.
- How can thick client apps be tested?
- Thick client applications require a certain
strategy when it comes to a penetration test
because they are typically more involved and
customized than online or mobile applications. - When dealing with a thick client application, the
initial step is to obtain data, such as - Identifying the technologies being utilized on
both the server and client sides. - Determining the behaviour and operation of the
program. - Locating the entire various user input entry
- locations.
- Recognizing the applications primary security
techniques.
4- Recognizing widespread vulnerabilities in things
like languages and frameworks. - Phases of Thick Client Application Vulnerability
Assessment Penetration Testing - Mapping and Scoping
- Make a business process model and agree to it. By
identifying and regulating access to documents
and information, scoping ensures their security.
It makes it possible to map out the problems for
subsequent steps. A brief meeting with the
client will be required as part of this process
to review and confirm the rules of engagement
for Thick Client Penetration Testing as well
as to establish the project scope and testing
schedule. - Enumeration and Information Gathering
- The tester receives information from this stage
that can be used to find and take advantage of
vulnerabilities in the online applications. This
phases objective is to detect any sensitive
data, such as application technology, usernames,
version information, hardcoded data, etc., that
may be useful during the testing phases that
follow.
5- Scanning
- To identify recurring problems in the thick
client software, we employ a proprietary method.
For our experts to investigate the tool also
lists the thick clients network communication,
inter process communication, operating system
interactions, and other activities. - Vulnerability identification and assessment
- The list of all targets and apps that fall under
the scope of the vulnerability analysis phase
will be compiled at both the network layer and
the application layer. Our experts examine the
setup of your thick client, detecting both
issues with the default configuration and
potential methods the application could be set
up to avoid security measures. - Exploitation
- All potential vulnerabilities found in the
earlier stages of the assessment will be
subjected to this phases effort to exploit them
like an attacker would. Business logic problems,
bypasses for
6- authentication and authorization, direct object
references, parameter manipulation, and session
management are all included in this. The majority
of thick clients make use of some server-side
capability, and all thick clients or central data
storage may be impacted by a server-side
vulnerability that is successfully exploited. - Need Penetration Testing for Thick Client
Applications? - Regardless of whether your thick client
application is hosted internally or in a
virtualized environment, Elanus Technologies
evaluates it. - When conducting security assessments for thick
- client applications, we look at best practices
for authorization and authentication as well as
data storage and communication pathways. To
assess your application, we use manual and
automated pen-testing procedures using paid,
free, and open-source cybersecurity. - We at Elanus Technologies specialize in thick
client application security, including - Static Analysis To find potential flaws and
- vulnerabilities in the applications source code
7- without actually running it, our professionals
use cutting-edge methods. - Dynamic analysis To find any flaws or
weaknesses in the functionality of the
application, our specialists run the application
and examine its behavior while it operates. - Penetration testing During this process, we
mimic a real-world assault on the application - in order to find and exploit vulnerabilities and
provide a comprehensive evaluation of its
security posture. - Review of Configuration Our team of specialists
examines the configuration of the application
and suggests modifications to - increase the applications general security.
- Network Traffic Analysis To discover and reduce
potential security concerns, our - professionals track and examine network traffic.
Security Code Review Our team of professionals
examines the applications source code for
security flaws, finding any potential problems
and offering solutions. - Thick client application security describes the
steps required to safeguard thick client
applications, which are computer or device
8software applications that run on end users'
computers or other devices and demand a lot of
resources and processing power. These programs
frequently work with sensitive data and are open
to many forms of assault, such as malware,
phishing, and hacking. We have expertise of
conducting Thick Client Application Security
Testing on client-server applications adopting
proven methods and technology. Get in touch with
