Secure Data Storage...

Security of your data is critical to both our businesses. The following measures are taken to ensure its safekeeping in our data center:

Physical Security

Physical access to our servers is restricted. They are located in a key-pad controlled, lockable, temperature-controlled computer room with an un-interruptible power supply. Servers are housed in a computer rack whose access is tightly controlled.

Network Security

All production servers are isolated on a private segment of the hosting center network without publicly routable IP addresses. Direct access to these servers from outside the data center is not possible.

Operating System Security

Each server is protected by host operating system security. On all platforms, each executable, data file, and directory is independently given read, write, and execute access on a per-user or per-group basis.

Database Server Security

We have implemented restricted access to the Data Archive and the Point Database beyond what is provided by physical, network, and operating system security. We have the ability to:

Restrict access to the database server
Control access to point attributes and/or data

Firewall Security

The firewall allows us to control access to the Data Archive at the IP address level. We manage all connections to the database, including subsystem connections and TCP/IP applications. We screen access based on the IP address of the machine trying to access the data.

Database Security

Database level security controls which users and groups can edit a specific table; for example, to create a point. Performance equations are considered another form of database point and are therefore protected through the same point security.

Point Security

Point attributes (zero, span, descriptor, etc.) have one access level and the point data values (snapshot and archive data) have another. Thus, it is possible to have different owners and different access for point attributes than for point data. Access levels are of three types:

Read and write
Read only
No access
