| Online free service for Web App Security |
What is it?
We are super excited to launch our FreeScan for Web Application Service. It is an online hosted service that can perform automatic security scan of websites or web applications. We have implemented tests for most commonly occurring issues in websites or web applications that can have a security impact.
Who is it for?
This service can be used by anybody with web presence, whose business continuity depends on confidentiality, integrity and availability of its website, business data and client data. Online businesses with strong brand presence can also use this service to look for common security issues to prevent loss of brand due to security incidents. Security engineers or administrators can benefit by scanning their web infrastructure using this service. If you are an enterprise with mass scanning requirements, this might not be the right solution for you. However, do get in touch, we might be able to offer something appropriate.
What does it offer?
The FreeScan for Web currently looks for a bunch of commonly occurring issues in web applications including:
- HTTP headers security
- HTTP cookie security
- HTTP insecure methods
- SSL/TLS crypto strength & security
- SSL/TLS configuration weakness
- Heartbleed
- Shellshock
Why is it Free?
We in 3S Labs have been doing a lot of Web Application Penetration Testing. In fact, web security test is perhaps one of our most frequently delivered service. Due to our prolonged involvement, we have been writing a bunch of miscellaneous scripts and tools for detecting common issues in web applications. Although the quality of any Penetration Test depends significantly on the skill and expertise of the tester involved, identification of many of the commonly occurring issues can be automated to a certain extent to increase productivity. FreeScan is our project to offer online hosted security services for free, using tools and techniques that graduate out of our research lab. We intend to maintain and extend this service based on our R&D output. However, only tests that can be implemented automatically with a certain degree of reliability and can be executed in a fixed time will be added to FreeScan. This means, you can test your applications for common issues, however for serious security requirements (quality & coverage), you still need a good and experienced security consultant.
Due to the scope and architectural pattern used in developing FreeScan service, it can be easily scaled up or down depending on demand. We should be able to support scanning of a large number of websites or web applications using this service. However, due to the open nature of the service, misuse may be eminent. In order to prevent misuse, we have currently considered a manual approval of scan. In future, we might consider automating the ownership verification of a site to limit misuse and legal issues on our part.

Coverage and Quality
A conventional Web Application Penetration Test consists of roughly the following steps:
- Application discovery through web page crawling.
- Attack surface enumeration based on detected functionality.
- Testing various input/output flows for possible vulnerabilities.
- Business logic testing.
- Framework/technology specific testing.
In this case - [1], [2] & [3] are directly related i.e. based on the quality of [1] & [2], the effectiveness of [3] will be determined which is the most important part of a proper web application security testing. Apart from that, a security consultant must also enumerate various business logic in the application and test them duly for possible violations. In general, a web application test with good coverage requires significant human intervention and cannot be automated fully. Due to the nature of human intervention, the quality of findings depends on the skill and experience level of the person involved in testing.
We are not trying to build a full fledged web application security scanner. The complexity involved in developing and maintaining such a software is beyond the scope of this service. However, for all practical purpose, it has been noticed that roughly 20% of the vulnerabilities (or weakness) appears 80% of the time. Many of these issues are trivial to detect and can be automated as well. We want to implement these tests in our FreeScan service so that our service can be used to quickly identify most commonly occurring issues in a website or web application.
Due to our in-house R&D capability, we are in a position to respond quickly to critical vulnerabilities that are discovered or found exploited in the wild. We intend to add detection capability in FreeScan for critical vulnerabilities that are discovered in the future. For example, we were able to analyze, reproduce and add test for Shellshock vulnerability disclosed recently. FreeScan for Web Application supports scanning for Shellshock vulnerability in web applications.
