All,

For your review, here is my own, abridged version of TunTrust’s value
justification.

See https://wiki.mozilla.org/CA/Quantifying_Value and
https://bugzilla.mozilla.org/attachment.cgi?id=9226817 .

*Ownership and Management Structure*

The beneficial owner of the TunTrust Root CA is the Agence Nationale de
Certification Electronique (“ANCE”) under the Ministry of
<https://www.mtc.gov.tn/> Communication Technologies of Tunisia
<https://www.mtc.gov.tn/> pursuant to Law no. 2000-83 of 9 August 2000
<https://www.tuntrust.tn/sites/default/files/reglementations/loi_2000-83_fr.pdf>
.

and report to Board of Directors)

ANCE (TunTrust) implements and maintains an Integrated Management System
(IMS) that complies with ISO 9001 and ISO 27001. The IMS design is based on
a Plan-Do-Check-Act (PDCA) approach to ensure continuous improvement of
compliance and incident management processes to meet security, quality and
compliance requirements.

*CA Hierarchy Highlights*

· TunTrust Services CA: This issuing CA is restricted to only issue OV SSL
certificates to domain names under “.tn” top-level domain and owned by
entities operating under the Tunisian Jurisdiction.

· TunTrust Qualified CA: This issuing CA is technically constrained to
prevent issuance of SSL- certificates.

· Starting June 2022: Issuing S/MIME certificates in compliance with the
currently-in-progress CA/B Forum S/MIME Baseline Requirements. S/MIME
certificates would be used on Tunisian national platforms: e-banking
services, e-gov services, e-health, etc.

· Starting June 2023: Issuing SSL Certificates with no constraints on the
top-level domain name, nor on the entity's jurisdiction starting June 2023.

*Budgeting*

TunTrust's budget document is uploaded here:
https://bugzilla.mozilla.org/attachment.cgi?id=9228562

It's annual compliance budget is determined based on:

· The compliance plan derived from the continuous risk assessment;

· Action plans derived from external and internal audit reports;

· Resources identified by each department of TunTrust that are required to
achieve compliance and to maintain and improve the TunTrust IMS; and

· As new technology becomes available, the possibility of introducing it to
improve the efficiency and security of the IMS is to be considered.

The compliance annual budget is validated by the board of directors and
then approved by the Ministry. TunTrust holds monthly follow-up meetings to
prevent forecast deviation and ensure enough budget allocation in case of
unforeseen compliance issues. The annual budget can be updated in case of
urgent compliance issues, and TunTrust indicates that it and its Board are
willing to allocate the necessary budget in a timely manner to quickly
address compliance incidents (prevention and/or remediation actions).

*CA System*

TunTrust uses Primekey EJBCA Enterprise Solution, with a subscription to
professional support and maintenance to keep its CA updated and compliant
with audit and policy requirements. Hardware and software are purchased
with vendor support and maintenance services to have access to the latest
stable releases and security patches. TunTrust's continuous investment plan
is to improve its infrastructure through maintenance services and
procurement strategies to acquire new hardware/software aiming at improving
the efficiency and security of the IMS. All systems and equipment that
would be in End-of Life or End-of-Support states are substituted with
upgraded versions or newer equipment.

*Personnel*

Key TunTrust personnel appear to have sufficient PKI domain experience and
system and security training.

Individuals in trusted roles receive regular training on evolving
technologies and changes to audit frameworks and requirements (WebTrust,
CA/B Forum, Mozilla Security Policy, ISO 9001 and ISO 27001). TunTrust also
conducts an annual security awareness program.

Annual risk assessments evaluate the strength of the compliance team in
terms of numbers and expertise.

*Compliance*

TunTrust uses PDCA/continuous improvement, change management processes, and
a watch process.

As evidence of its proactive approach to compliance, TunTrust omitted the
OU field from its OV SSL Certificate Profile in advance of CABF Ballot SC47.

With respect to the documented watch procedure, engineers from the Audit
and Risk Analysis Department are formally designated to regularly report to
the Board of Directors about any potential compliance issue or newly
adopted approaches that they might find about while following:

· Discussions in Mozilla's dev-security-policy forums (the previous and the
current ones);

· Updates to the Mozilla root store policy (starting from the discussions
on the draft on Github);

· Mozilla Incident Dashboard - CA incidents and misissuance reports;

· Discussions in the Working Groups and Subcommittees of the CA/B Forum -
subscribed to the mailing lists of the SCWG, the Validation list, the
Public list, the NetSec list and the Infrastructure list;

· New ballots from the state of “Under Consideration” to the “Review
Period” of the Guidelines;

· The CT logs group, https://groups.google.com/g/certificate-transparency;

· Chromium CT policy <https://chromium.github.io/ct-policy/ct_policy.html>and
Certificate Transparency Logs that are recognized by
<https://cs.chromium.org/chromium/src/components/certificate_transparency/data/log_list.json>
Chromium,
https://cs.chromium.org/chromium/src/components/certificate_transparency/data/log_list.json
;

· Updates to linting tools (zlint, cablint, certlint);

· Updates to Microsoft Root Store Policy Program Requirements and Audit
Requirements;

· Updates to the WebTrust Principles and Criteria on the website of CPA
Canada;

· Updates to the ETSI standards on the etsi.org website;

· Updates to the ISO 9000 and 27000 series on the iso.org website.

Engineers from the Technical Department and from the Audit and Risk
Analysis Department are formally designated to regularly report to the
Board of Directors about any technical updates and new recommendations in
the PKI and Information Security industries that may impact its systems.

*Automation*

As part of its continuous infrastructure development strategy, automated
security and compliance controls are continuously enforced in addition to
real-time monitoring and alerting systems. TunTrust has implemented
automation in its systems and equipment, such as:

· Automated monitoring systems that detect configuration changes and alerts
administrators in real-time of these changes;

· Automated systems that monitor system and equipment performance (CPU,
RAM, disk space, etc.) and alerts administrators in real-time of any
problems;

· Control over Certificate Attributes to conform to the CA/B Forum Baseline
Requirements (such as prohibiting the underscore character, etc.);

· Automated Patch Management for Windows systems (Ongoing automation for
RedHat systems, refer to incident bug
<https://bugzilla.mozilla.org/show_bug.cgi?id=1663953>);

· System and network audit logging process, backup and recovery, and IT
asset inventorying;

· Pre-configured EJBCA Validators: CAA Checking, Black List Checking and
Weak key Checking; and

· Lint Checking: TunTrust uses zlint, cablint and certlint as linting tools
before Certificate Issuance.

*Risk Assessment*

TunTrust’s risk assessment is updated annually (as part of the annual
compliance program) and before implementing major changes (new platforms,
major updates to systems, physical and environmental changing factors,
etc.). It includes strategic and operational risks. The risk assessment and
risk mitigation plan are reviewed by independent auditors in the context of
audits performed. TunTrust maintains and regularly (at least annually and
before major changes) updates its risk assessment using ISO 27005 for risk
management. Per the ISO 27001 audit, TunTrust is required to justify all
decisions taken to deal with the identified risks.

*Audits and Assessments*

TunTrust undergoes:

· WebTrust Audits since 2019;

· ETSI audits since 2015;

· ISO audits since 2015;

· An annual information security audit as mandated by the Tunisian National
Law <https://www.ansi.tn/sites/default/files/loi%205-2004%20FR.pdf>. This
mandatory audit includes a technical audit (vulnerability scan, internal
and external pentesting, etc.), an organizational audit (in accordance with
the ISO 27001 standard) and a risk assessment (in accordance with the
ISO27005 standard); and

· Internal audits of systems and processes in accordance with compliance
requirements.

*Summary*

In summary, TunTrust has:

· a regularly reviewed risk assessment that covers operational risks;

· automated monitoring systems that detect changes to configuration files
and other security events and send real-time alerts;

· security and quality metrics that are controlled through periodic
self-audits, vulnerability scans and internal and external penetration
tests; and

· automation and minimized human actions on systems where possible.

Based on my reading of TunTrust's value justification, it appears that we
should move forward with approving TunTrust's application for CA inclusion.
I look forward to any additional comments.

Sincerely yours,

Ben
