OUR APPROACH

AppCheck was designed from the ground up to emulate the process of a professional penetration tester to ensure maximum coverage and accuracy

AppCheck takes a first principals approach to application vulnerability detection, and therefore is not bound to any platform or signature database.

Rather than use a database of static signatures, AppCheck approaches each test in the same way a hacker or penetration tester would and applies a testing methodology. The vast majority of application security flaws, such as SQL Injection and Cross-Site Scripting arise from insecure processing of input supplied by the client. AppCheck adopts a first principals approach when testing each input by examining the original expected value and the servers response when the value is modified. By adopting this methodology, AppCheck is able to determine how data may be being processed by the server and can then dynamically evolve each test to identify vulnerabilities. This approach results in more accurate testing and allows AppCheck to identify security flaws that may be masked by security filters and Intrusion Prevention Systems (IPS), but could still be exploited by a real-world attacker.

Crawling and content discovery crawling

The AppCheck crawling engine uses a combination of application modelling techniques and subtle heuristical cues to automatically discover the complete attack surface of any given application in the shortest time possible. The algorithms are designed to model how a penetration tester or attacker would explore the application, utilising visual cues and ruling out equivalent instances of the attack surface if they have already been explored.

All of this means that for each target discovered we know its state at discovery and how to re-create that state to later attack it; and because the scanner is behaving in a more human way, it opens up attack vectors that are inaccessible to less sophisticated crawlers.

How our intelligent crawling works

Identify identical components

An ecommerce application may have several thousand product pages, with each one implementing the same code path within the application. AppCheck identifies these cases and avoids wasting time on identical components.

Identify & replicate behaviour

The application may have components that need to be accessed in a specific sequence, for example, navigating from a product page through a shopping basket flow. AppCheck is able to identify this behaviour and ensure the complete process is followed for each vulnerability check.

Open source intelligence gathering

Whilst the AppCheck crawling engine does an excellent job of enumerating the visible attack surface, it can sometimes be the hidden components that are the Achilles’ heel.

Temporary components such as micro-sites and marketing landing pages can become forgotten and unmaintained. These no-longer linked components may hide a critical security flaw and therefore it is important we test every component an attacker may target. AppCheck queries search engines such as Google and other online indexing services to gather a list of URLS both past and present to factor into the attack discovery phase.

Our approach to testing

Web Application scans can be started in just a few seconds by entering a list of URLs into the AppCheck user interface and either selecting one of our extensive pre-configured profiles or by building your own scan configuration. Once started, AppCheck combines open source intelligence gathering and a sophisticated browser based crawling engine to identify application components that could be vulnerable to attack.

Application Scanning

For each URL configured with the scan, AppCheck performs online reconnaissance to gather information pertaining to the site that is publicly available in search engines and other online indexing services.

Next AppCheck will map out the application using a sophisticated crawling engine. The crawler combines traditional web scraping with a browser-based crawler which implements artificial intelligence to mimic typical application user behaviour.

The “Mapped Attack Surface” enumerated during the initial phases of the scan, is then subject to methodical security testing. Typically, the assessment process works by taking each user supplied data component, such as a form field of query string parameter, then modifies it to include a specific test case before submitting it to the server. Based on the applications response, further test cases are then submitted through the same method to confirm the vulnerability.

Common vulnerabilities detected during the web application scan include; Injection flaws such as SQL, NoSQL, XML, Code, and Command injection, Cross-Site Scripting and hundreds of other vulnerability classes arising from insecure code.

Infrastructure scanning

In this context, “Infrastructure” includes all components that are not covered within the application scanning phase. The infrastructure scan beings by port scanning each host to identified accessible services. Each service is then probed for vulnerabilities such as missing security patches, configuration weaknesses and information disclosure vulnerabilities.

Common vulnerabilities detected during the infrastructure scanning phase include; missing operating system patches, weak administrative passwords and access control vulnerabilities.

If the target system is hosted within Amazon Web Services, Google Cloud or Azure, specific configuration assessment modules are launched to identify common configuration weaknesses.

Reporting

At completion, AppCheck provides a detailed report listing the potential impact, a technical narrative detailing how the flaw was detected and detailed remediation advice. Where possible, proof of concept examples are provided so that the flaw can be easily recreated and demonstrated to the relevant stakeholders.

Users can either manage all vulnerabilities through the vulnerability management dashboard, or at the click of a button download custom filtered results and view via HTML, Docx or CSV. AppCheck includes a simple JSON data API for retrieving, aggregating, processing and reporting raw vulnerability data for use in third party applications.

Additionally, multiple (unlimited) user accounts can be created to allow team collaboration. AppCheck includes workflow management allowing you to assign and prioritise each vulnerability’s remediation to nominated members of your team.

AppCheck at Frost and Sullivan

We tested multiple DAST solutions and AppCheck stood out as the tool to tick all of the boxes. We needed a scanner that allowed simple yet granular configuration, a dashboard that enabled multiple departments to manage any discovered vulnerabilities, would give us great vulnerability detection coverage and that came within our budget. AppCheck did this and more and their support team offer useful guidance on getting the best out of the tool, as well as keeping us updated with the latest threats and security news.

AppCheck at ESP Group

When we compared AppCheck against a team of manual penetration testers, AppCheck identified all of the same vulnerabilities, plus an additional three critical vulnerabilities and did so in under half the time. This demonstrated how advanced AppCheck was as a web application security scanner and how cost effective it is compared with manual testing. We see AppCheck being a long term tool in our security management system.

We have worked with Appcheck for over 3 years and in that time we have found Appcheck personnel to be professional and knowledgeable. The system is very easy to use and penetration testing is decisive with results produced in a very precise format that is visibly and textually informative.

Pam, IT Manager
AppCheck at Cartrefi Cymuneol Gwynedd

AppCheck has taken the stress out of penetration testing, gone are the weeks of liaising with vendors and honing scan profiles to produce a once a year report, regular automated scheduled scans means we can relax while AppCheck does the heavy lifting.

Richard, Infrastructure Manager
AppCheck at Saint Gobain

We are very pleased to have AppCheck as part of our toolkit and it plays a key role in securing our 90+ websites. It has become a fundamental part of our website deployment process, with all new releases being scanned prior to going live which has enabled us to identify zero day vulnerabilities and delay releases until they have been resolved. AppCheck is very easy to use, with the reports generated being very easy to read and interpret, enabling us to be able to forward vulnerabilities on to our various development teams and partners for a swift resolution. The best thing is that I know we have only scratched the surface in terms of AppCheck’s capabilities, yet already it has proved to be a valuable addition so hopefully we can continue to get more out of the platform.

AppCheck at Queens University Belfast

The main benefit of Appcheck for us is the speed with which we can spin up a test. The application compares well with manual testing and indeed has found significant vulnerabilities on a number of occasions. The reports are well structured and ready for presentation to senior management with minimal editing.

Chris, Data Security Manager

We use AppCheck as part of our security strategy, due to its ease of use and clear and concise reporting functions. Compared to manual pen-testing we find AppCheck much easier and more cost effective and feel confident vulnerabilities are being picked up all year round. Their support team are always on hand for any queries we may have. I would definitely recommend AppCheck if you're looking for a market leading solution that covers all bases.

Ian, ICT Security Manager

Leeds Credit Union have been using AppCheck’s services for some time now and we have found their staff to be friendly and very helpful in getting the product to do exactly what we want. The process is quite straight forward and the staff at AppCheck are always eager to answer any questions we may have. We have tried other products that have been way more expensive as well as onsite penetration testing but found that AppCheck easily beat them both in terms of costs, depth of coverage and the ability to re-test at no extra cost when any vulnerabilities are resolved. We would have absolutely no problem in recommending them to any company.
