Client-Side Application Security Testing

Client-Side Application Security Testing tests “thick” applications that are run and/or installed on an endpoint (workstation, server, etc.). It is typical to perform this in conjunction with Web Application Security Testing when the application is an “agent” running on the endpoint and interacting with a web service/API.

Testing involves automated and manual evaluations of one or more applications to ensure they provide protection against abuse of your data. We use industry standard tools to carry out automated scans looking for well-known vulnerabilities, and we also conduct manual testing to find vulnerabilities and attack vectors not otherwise detectable by automated tools.

More than a Vulnerability Assessment

This is more than a simple vulnerability assessment. We actively attempt to circumvent security controls by carrying out exploits that take advantage of discovered vulnerabilities, revealing what an adversary would be able to do. During testing, we look for any method that can violate the CIA Triad security model (confidentiality, integrity, availability).

  • Confidentiality is limiting information to only the authorized person(s) who should have access to it.
  • Integrity is ensuring data/communication at rest or in transit can only originate from, be sent to, or be modified by an authorized person(s).
  • Availability is the ability for an authorized person(s) to access the resources when needed.
Schedule a Consultation

The purpose of testing is to enumerate your exposure (within the given time constraints), identify and verify as many vulnerabilities as possible, ensure the security of your application is strong, and then provide actionable solutions to help you protect against attack/compromise. For example, we use industry standard tools to scan for and verify well-known/unpatched vulnerabilities that allow an attacker to carry out remote code execution and privilege escalation, circumvent intended controls, gain access to sensitive data, etc. In most cases, we will leverage the discovered vulnerabilities to (1) verify it is exploitable and (2) determine the exposure, should it be breached.

The testing is largely centered around static code analysis, fuzzing, and manual analysis using our internal/proprietary methodologies.

DISCLAIMER: Sample pricing listed is not actual pricing. These dollar amounts are estimates based on the number of hours required for engagements of similar size and assumes white box testing and at least a 60-day lead time. They are provided to give you a ballpark idea of the cost for the service. The total cost will be based on the estimated number of hours needed to perform the requested service and our hourly rate. Black box testing, specific complexities, and other non-standard situations will increase costs. Additionally, sample pricing does not include travel or other non-standard expenses (specialized equipment, materials, etc.). Final pricing is determined during the no-obligation scoping phase (before testing starts).
