5. Facility, Management, and Operational Controls
The CA/Browser Forum's "Network and Certificate System Security Requirement" isfully incorporated into this document by reference.
The CA SHALL develop, implement, and maintain a comprehensive security program
designed to:
1. Protect the confidentiality, integrity, and availability of Certificate Data andCertificate Management Processes;
2. Protect against anticipated threats or hazards to the confidentiality, integrity, andavailability of the Certificate Data and Certificate Management Processes;
3. Protect against unauthorized or unlawful access, use, disclosure, alteration, or
destruction of any Certificate Data or Certificate Management Processes;
4. Protect against accidental loss or destruction of, or damage to, any Certificate Dataor Certificate Management Processes; and5. Comply with all other security requirements applicable to the CA by law.
The Certificate Management Process MUST include:
1. physical security and environmental controls;
2. system integrity controls, including configuration management, integrity
maintenance of trusted code, and malware detection/prevention;
3. network security and firewall management, including port restrictions and IP
address filtering;
4. user management, separate trusted-role assignments, education, awareness, andtraining; and5. logical access controls, activity logging, and inactivity time-outs to provide
individual accountability.
The CA's security program must include the following annual risk assessments:
1. Identifies foreseeable internal and external threats that could result inunauthorized access, disclosure, misuse, alteration, or destruction of any
Certificate Data or Certificate Management Processes;
2. Assesses the likelihood and potential damage of these threats, taking into
consideration the sensitivity of the Certificate Data and Certificate Management
Processes; and3. Assesses the sufficiency of the policies, procedures, information systems,
technology, and other arrangements that the CA has in place to counter suchthreats.
Based on the Risk Assessment, the CA SHALL develop, implement, and maintain asecurity plan consisting of security procedures, measures, and products designed toachieve the objectives set forth above and to manage and control the risks identified
during the Risk Assessment, commensurate with the sensitivity of the Certificate Data
and Certificate Management Processes. The security plan MUST include administrative,
organizational, technical, and physical safeguards appropriate to the sensitivity of the© 2003 SECOM Trust Systems Co., Ltd.

Certificate Data and Certificate Management Processes. The security plan MUST also
take into account then-available technology and the cost of implementing the specificmeasures, and SHALL implement a reasonable level of security appropriate to the harmthat might result from a breach of security and the nature of the data to be protected.
5.1 Physical Controls
5.1.1 Site Location and Construction
The systems of the CAs (hereinafter, "CA Systems") are located where they will not beeasily damaged by water exposures, earthquakes, fires or any other disasters, andstructural measures have been implemented to prevent and protect against suchdisasters. In addition, the equipment and instruments used in the facility shall be
installed in secure locations implementing the anti-disaster/hacking/breaking &entering measures.
5.1.2 Physical Access
The hardware and software used by the CAs employ an appropriate security control
combining physical and electronic access controls. Access to the hardware and thesoftware providing the CA Services are continuously monitored and requires permission
by the Service Operation Manager(s).
5.1.3 Power and Air Conditioning
The installation room for the CA Systems secure the power source with sufficient
capacity to operate the CA Systems and is protected through the power supply from the
backup generators during long-lasting power outages. Further, the CA Systems are
installed in an air conditioned environment where optimum temperature and humidity
can be maintained constantly using air conditioners.
5.1.4 Water Exposures
The installation room for the CA Systems implement the protection against the water
exposures, including deployment of the leakage sensors.
5.1.5 Fire Prevention and Protection
The installation rooms for CA Systems are in a fireproof compartment partitioned off by
firewalls and equipped with fire alarms as well as fire extinguishing equipment.
5.1.6 Media Storage

5.2.1 Trusted Roles
Individuals involved in the registration, issuance, and revocation practices are acting in
the capacity of a trusted role conforming to this CPS and the relevant CP. The CAs do
not centrally assign operational roles to a specific individual, but allocate authorities tomultiple personnel. The roles in the CAs are listed in "Table 5.2-1 Trusted Roles".
