VPN <br />provides a secure & encrypted communication tunnel to allow the use of <br />tools such as RDP or VNC These tools allow secure- remote connectivity to <br />servers /computers within the network. XV Solutions is experienced in <br />creating VPN gateways, and training staff on methods to securely connect <br />into internal networks. <br />Y Remote connections are validated for access into the private secured <br />network via two different methods: (1) the VPN profile for each user has <br />unique feature codes that are only known to the City of Santo Ana devices. <br />This prevents brute force attacks into the VPN from external threats. (2) The <br />SCADA server configuration for DYNAC ES contain specific end -point devices <br />and their IP addresses that are allowed access to the SC40A portal. XV <br />Solutions is familiar with both access control validation methods for remote <br />connections. <br />Y XV Solutions has experience managing both Dynamic IP addresses, which are <br />typically used for mobile devices and workstations, and static IP addresses, <br />which are usually required for servers. <br />Dynamic IP addresses are managed with a DHCP Server. Windows Server <br />operating systems, such as Windows 2003, Windows 2008, and Windows <br />2012 come with a built -in DHCP Server service that can be turned on and <br />configured to dynamically assign 1P addresses to devices connected to the <br />network. Some appliances, like the Netgear SRX5308 also come with a built - <br />in DHCP server that can be used for this purpose. <br />ff <br />XV SOLUTIONS Page 5 <br />Critical servers, like SCADA servers, SMTP /Email servers, Microsoft <br />SharePoint, and other application servers require a static IP address. Static <br />IP addresses can be reserved in a DHCP server. <br />3 —h <br />RAID Y RAID (Redundant Array of independent Disks) is a method of grouping. <br />Configuration multiple hard- drives, so that the OS views multiple drives as one logical <br />Support drive. There are several advantages to RAID configurations, such as <br />increased read /write performance and redundancy. XV Solutions has <br />expertise in creating various types of RAID configurations, and has <br />configured RAID -5 for the Water Resources Division. <br />3 —i <br />VPN Support Y Knowledge in configuring Netgear VPN Router and Cisco ASA firewalls to <br />allow external systems VPN access to internal network. <br />3 —i <br />Network Y Experience with SCADA Dynoc ES redundant server, where there is a primary <br />Redundancy server and a stand -by server. When the primary server faits, the secondary <br />server takes over and becomes the primary server. Servers use a virtual iP <br />address, so that the primary server is always seen on the virtual IP address. <br />Both servers have their own typical IP address, but users always connect <br />using the virtual IP address which will always connect users to the whichever <br />server is the primary server. <br />3 —k <br />Reporting Y Yes, monthly reports can be easily prepared and delivered via email, posted <br />on the SharePoint server, added to o file server, or any other method that is <br />convenient or desired. <br />ff <br />XV SOLUTIONS Page 5 <br />
