He also refers to the excellent support provided by Innominate, stating that help was always provided very quickly when problems arose. The possibility to also integrate the secure remote services technology into existing systems without “default gateway or standard gateway” was important to Zippe. The “Remote VPN NAT” function is used to map the entire data traffic, which travels over the VPN, on the local network via the configured address. As a result, a default gateway is not required. Legacy systems are also due to be opened for remote services in the near future with an additional feature of the mGuard firmware. Up until now, plant operators have refused access to legacy systems running Windows NT or Windows 95 for security reasons. mGuard CIFS Integrity Monitoring, an optional firmware module, provides an industrial-strength alternative to antivirus software. In order to do so, Windows network drives are checked regularly to determine whether certain files (such as *.exe, *.dll) change unexpectedly in comparison to a reference state. The module also facilitates an external virus scan on drives of systems that are located “behind” mGuard, which cannot otherwise be reached from the outside (e.g. industrial PCs in production cells), and cannot use antivirus software that is installed locally. CIFS Integrity Monitoring thereby offers improved protection for file shares which are frequently used for exchanging data with the environment, based on the CIFS/SMB family of protocols. These are a gateway for malware. Damage caused by “zero-day” exploits can also be detected with the CIFS integrity check. In connection with the firewall, which isolates the customer network, VPN access can also be achieved for poorly-secured legacy systems.
