source/faq/index: Update FAQ.

Update the FAQ with additional entries as requested by CTI TAC
review.

Add information about relevant national standards and why we want
to advance the state of our current infrastructure.

Add information about service bringup and how to achieve that.

 meet more stringent expectations to maintain the trust of the ecosystem. It is
 with this context in mind that CTI has been formed.
 
+The global focus on security is clear and present and in direct relation to
+the effective functioning of economies and societies. The GNU Toolchain plays
+a hugely important role in companies and communities of all sizes, providing
+tooling for compilation, assembly, linkage, running and debugging of
+critical software.
+
+In order to continue to support these communities we must start to adhere to
+the modern cybersecurity principles including moving towards zero-trust
+architectures with strong application sandboxing for all provided services
+e.g. NIST SP.800-207, separate and protect each environment involved
+in software development e.g. NIST SP.800-218A PO.5.1, and use multi-factor,
+risk-based authentication and conditional access for each environment.
+
+Governments around the world have increased their focus on Cybersecurity and
+resilience in the face of cybersecurity attacks. In the European Union with
+the creation of the Network and Information Security Directive (NIS 2016/1148,
+NIS2 2022/2555), the Cybersecurity Act (2019/881), and now the Cyber Resilience
+Act (2022/0272). In the United States with the publishing of the Executive
+Order 14028 "Improving the Nation's Cybersecurity", with NIST's
+Secure Software Development Framework (SSDF SP 800-218A), Cybersecurity
+Framework 2.0 (CSF 2.0), and Software Supply Chain Security Guidance.
+
+Several of the components of the GNU Toolchain meet the definition of NIST's
+"critical software" since they underpin ICAM (Identity, Credentials and
+access management), network control (DNS stub resolver), and key operating
+system components. We want to expand and continue to support FOSS in all
+of these use cases we should strive to meet the increasing cybersecurity
+best practices.
+
+The purpose of CTI is to help meet these requirements now and into the future
+to ensure FOSS and the GNU Toolchain can be used by these users and communities.

+How are services validated prior to migration?
+""""""""""""""""""""""""""""""""""""""""""""""
+Services are validated on a per-service basis, with per-service functionality
+being tested. Given the focus on strong service isolation and resilience the
+inter-service integration pieces can and should be added in stages e.g.
+email to bugzilla, git send-email to mailing lists, as services that can
+communicate are brought online.
+
+The intent is not to stand up a monolithic integrated set of services, but to
+start small and create well-isolated services that can operate independently
+with loose coupling.
+
+Are all services migrated at the same time?
+"""""""""""""""""""""""""""""""""""""""""""
+There are no plans to construct a prototype of the entire constellation of
+enumerated services for a project that is to be migrated to CTI services.
+
+Instead the approach taken is to stand up well-isolated services that can
+operate independently of each other and with high resilience, and then add
+the inter-service integration functionality.
+
+Since many of the services being provided are known to already be deployed
+in production for other projects there is a lot of existing experience
+to support deployment. What needs to be done is to ensure stronger isolation
+between services as part of improving the project's cybersecurity position.

 Are there any presentations covering CTI?

 Yes, in October 2022 the CTI TAC gave an `FSF hosted community Q&A <https://media.libreplanet.org/u/libreplanet/m/the-gti-project-a-conversation-and-community-q-a/>`_.
