VPSRemote Configuration The VPSRemote is configured with devices installed at the customer site for remote operation and linked to the secure YOKOGAWA Center System, which provides a safe network communication environment to connect these devices and systems. YOKOGAWA Center System VPSRemote Server Customer Firewall Site Router Customer Network Preventive Maintenance Site B KVM Switch Maintenance PC Applicable System Device for Remote Remote Site *1: Internet Service Provider High-tech Security Measures Stringent access control Recovery Support ● The connection to the customer’s system is limited to the Internet domain only for VPSRemote. It cannot be accessed from the other domains. ● The firewall of VPSRemote is extremely powerful and safe because all the communication ports for accessing the internal network from the Internet are closed. Accessing from an outside network is not allowed. ● Inside of the firewall, the system rejects all access from ping sweeps or port scans from the Internet. Therefore, it makes it difficult for hackers to target the system for unauthorized access, which significantly reduces risk. Operation Support Secure encryption communication ● The communication connection with customers utilize SSL-VPN (Secure Socket Layer Virtual Private Network). Since communication data is strictly protected and managed by authentication or encryption, there is no risk such as interference, disclosure, sniffing, and spoofing. Safe and foolproof user authentication ● In order to clarify the identity of the access user, the originator IP address is registered in advance in the user management system, which prevents unauthorized third person access. ● A one-time password is used for user authentication. A one-time password is valid for only one login session or transaction. After it is automatically issued to the user, it can only be used by that person. This minimizes the risk of a password being stolen, and avoids the risk of abuse. Security by access monitoring ● In order to detect an unauthorized access from hackers early on and to take effective measures against the problem, YOKOGAWA has established the 24/7 access monitoring system operated by security experts. If the system is attacked by hackers, the entire network is shut down and any potential damage is minimized. VPSRemote/Remote Solution Service is a part of the Lifecycle Agreement that helps customers maintain stable operation of their systems.
