Vierailijat pääsevät turva-alueille ainoastaan luvan kanssa, asiallisesti tunnistettuina ja heidän pääsyoikeutensa on rajattu ainoastaan tarvittaviin tiloihin. Kaikki vierailut kirjataan vierailijalokiin. Lisäksi henkilöstöä on ohjeistettu turvalliseen toimintaan vierailuihin liittyen.

Individuals other than those properly authorized by the organization (visitors) must always be accompanied by an escort. The host of the visitors must have independent access rights to the security area being visited, as well as the authority to host visitors. Visitor procedures must ensure that the confidentiality of the information processed or stored in the area is not compromised.

Maintenance activities in the area may only be performed by, or under the supervision of, personnel with independent access rights. Information processing in the area is prohibited during maintenance, installation, and cleaning activities if there is a risk that the personnel performing these tasks could gain access to the protected information.

Unescorted visitor procedures may be approved for those visitors who meet the requirements for granting access rights.

The organization has approved a procedure for visitors, which may address, for example, the following matters:

• Visitors are identified and provided with a visitor badge.
• Visits are recorded.
• Visitors are never allowed or left in the areas unsupervised, and the host is responsible for external persons throughout the visit.
• Staff are instructed on hosting visitors.
• Ensuring that visitors cannot unlawfully see, hear, or otherwise gain access to protected information.
• Staff are instructed to respond to individuals moving within the area without proper identification.

If entering a security area effectively grants immediate access to the classified information stored there:

• the highest security classification of the information normally stored in the area must be clearly indicated, and
• all visitors must have explicit permission to enter the area, must always be accompanied by an escort, and their reliability must be appropriately verified, unless it has been ensured that they will not have access to classified information.
