IEC 61587-6-2021 Mechanical structures for electrical and electronic equipment – Tests for IEC 60917 and IEC 60297 series – Part 6: Security aspects for indoor cabinets.
4 Security aspects for indoor cabinets
Security for electronic equipment should be designed from the point of view of both hardware and software. With respect to the security of hardware installed in a cabinet, the security aspects of the cabinet depend on the following factors:
a) access security level of the cabinet installation site (access security within the building);
b) security performance of the cabinet.
The access security within the building, as part of the physical security, is primarily aimed to be effective against unauthorized forced entry. In this regard, many international or regional regulations and specifications for building doors, gates, building door handles and key-locking systems and other building physical security facilities are defined.
The security performance of the cabinet is determined by the choice of specific handle, key, mechanical lock and other components, which are different from the hardware for buildings and are mostly dedicated to cabinets for electrical and electronic systems.
Designers and users should consider those points properly to establish security aspects for the intended use of the relevant indoor cabinet.
4.2 Access security level of the cabinet
In the case of the indoor cabinet, the access security level depends on building level restrictions to reach the cabinet installation sites. Figure 2 and Table 1 show typical access security levels in buildings or premises.
Security performance for the intended use cabinet should be appropriate for the access security levels shown in Table 1 . End users should use Table 1 to describe their installation location to cabinet providers.
5 Security performance levels of cabinets
Table 2 shows security performance levels of cabinets and related security performance levels of mechanical components.
Application of security performance levels of cabinets should be defined by the required security measures of the cabinet-mounted electronic system and the access security levels of the installation sites. Nevertheless, whatever the access security level of the installation site, the security level of the cabinet may be chosen independently with reference to requirements arising from the intended electronic system. Designers and users should study and clarify the actual conditions of the installation site and the required security measures of the intended electronic system, and apply the optimum security performance levels for cabinets.IEC 61587-6 pdf download.
