SafetyProduct manual 2CKA001473B9726 │82.5 Cyber-securityIndustry faces intensifying cyber security risks. In order to increase stability, security androbustness of its solutions, ABB has formally established cyber security robustness testing aspart of the product development process.In addition, the following measures are prerequisites for the safe operation of your free@homesystem.Prevention of access to the different mediaThe careful isolation oft he system against unauthorised access is the basis for each protectiveconcept. In the case of a free@home system, only authorised persons may have physicalaccess to the free@home system, as well as the System Access Point. During planning andinstallation all free@home media (cable and wireless) and all components prone to cyberattacks, must be protected as best as possible.Sub-distributors with free@home devices should be either locked, or located in room to whichonly authorized persons have access.Twisted Pair cabling■ The cable ends of the free@home Twisted Pair cable should not be visible or project outfrom the wall, neither inside nor outside the building.■ Bus lines in outdoor areas or in areas with limited protection represent an increased risk.Here the physical access to the free@home Twisted Pair cable should be mad exceptionallydifficult.IP cabling within the buildingThe local network serves as a sensitive component for secure communication. Therefore,unauthorized access to the local network must be prevented. As a result, the usual securitymechanisms for IP networks must be applied. These are, for example:■ Secure encryption of wireless networks.■ Use of complex passwords and protection of these against unauthorized persons.■ Physical access to network interfaces (Ethernet interfaces) should only be permitted inprotected areas.■ MAC filterConnection to the InternetTo prevent malpractice, no router ports from the Internet to the home network may be openedfor free@home components. For secure remote access a VPN tunnel or the myBUSCH-JAEGER Portal / MyBuildings Portal can be used.
