What is the CCSS? 

CryptoCurrency Security Standard (CCSS) is a set of requirements for all information systems that make use of cryptocurrencies, including exchanges, web applications, and cryptocurrency storage solutions. By standardizing the techniques and methodologies used by systems around the globe, end-users will be able to easily make educated decisions about which products and services to use and with which companies they wish to align.

CCSS is designed to complement existing information security standards (i.e. ISO 27001:2013) by introducing guidance for security best practices with respect to cryptocurrencies such as Bitcoin. CCSS is not designed to substitute or replace these standards; in fact, following the CCSS to the letter while ignoring standards like ISO 27001:2013 will likely lead to compromise. CCSS is a cryptocurrency standard that augments standard information security practices. As with any standard, knowledgeable and experienced security professionals and/or auditors are necessary when implementing any information system to ensure coverage of all classes of attack as well as the appropriate handling of all potential risks.

How does an entity with a cryptocurrency system start the audit process?

The first step to getting audited is to select a CCSSA. You can search our currently certified CCSSAs here. Entities then contact and negotiate with the CCSSA of their choosing. Please note that while these individuals have proven their knowledge of the CCSS, C4 does not endorse specific CCSSAs. It is imperative that entities follow best practices for selecting an auditor.

All CCSS audits cover a period of time prior to audit completion and will test the operating effectiveness of the control over this period of time. Audits are designed to be performed at least annually and cover the preceding 12 month period. All audits performed by CCSSAs are reviewed by a CCSSA-Peer Reviewer before C4 certifies an entity. Any dispute arising out of the peer review process shall be arbitrated by the CCSS Steering Committee.

The CCSSA is responsible for ensuring all data related to the audit is transmitted and stored in a secure manner for the duration of the Certificate of Compliance (CoC) and as legally required in the jurisdiction of the audit. C4 will not view documentation of evidence outside the Summary Report on Compliance (SRoC). The CCSS steering committee shall review evidentiary documentation in the case of a peer review dispute.

What is a CryptoCurrency Security Standard Auditor (CCSSA)?

A CryptoCurrency Security Standard Auditor is an expert in the CCSS. CCSSAs are able to apply the CCSS standard to any information system that uses cryptocurrencies, calculating a grade for the system according to the CCSS.

CCSSAs must avoid any potential conflict of interest. This may include current or previous employment, familial relationships, financial interest (such as tokens or equity held), or any other matters that may constitute a conflict of interest.

So strongly and metaphysically did I conceive of my situation then, that while earnestly watching his motions, I seemed distinctly to perceive that my own individuality was now merged in a joint stock company of two; that my free will had received a mortal wound.

It was a humorously perilous business for both of us. For, before we proceed further, it must be said that the monkey-rope was fast at both ends; fast to Queequeg's broad canvas belt, and fast to my narrow leather one.
