Web Application Rules in the .Trust Policy

2014-11-21 10:45

NCC Group has invested resources in developing and promoting the concept of a Top-Level Domain (TLD) where greater information assurance is provided — the .trust TLD. Note this service has nothing to do with the organisation TRUSTe mentioned yesterday.

Partial screen capture from a page on the NCC .Trust website that explains how .trust stands on three core principles: verify, secure and assure

The recently announced (October 2014) .trust technical policy defines five policy areas (abuse, DNS, email, network and web application), each with rules and sub-rules. Although .trust is not for me on this blog (nor by some parts of NCC that insist on using .guide and .com for information and resources, including the very confusing redirect URL https://trust.guide), it may gain commercial traction and I was interested to see how their policy mapped to other standards.

I have compared the web application policy rules with the OWASP Application Security Verification Standard (ASVS), OWASP Testing Guide (Testing), the OWASP Top Ten (T10) and the Payment Card Industry Data Security Standard (PCI DSS). This is from the perspective of the .trust technical policy, and a mapping does not mean "the same as".

So considerable overlap, but there are unique testing in each of the above.

The seven rules in the .trust Abuse Policy are also relevant for hosted content such as what is linked to, what is redirected to, avoidance of obfuscation, and the types of files hosted, especially aspects that might be considered malware.
