Measure: EntranceAccessControl


Implementation of an access control system for entrances to sensitive sites. Thus it shall be avoided that unauthorized people get access to the sensitive sites. The aim is to protect the infrastructures of the water utility from damages.


The physical access control can be implemented in different forms. The most common way of access control is the distribution of keys or access cards for sensitive sites only to authorized personnel. Another way of access control would be the implementation of regularly changing codes that are necessary to open doors. Also the access permission via biometric data like fingerprints is possible. In case of biometric entrance systems special attention has to be paid to data protection issues. Access control can also be realized by personnel that is positioned at entrances to check access permissions manually. The principle of minimum access permissions should be applied, that means that as few access authorizations as possible should be distributed.
