Security - Access Controls

The NetRS is shipped without security being enabled. This means that initially anyone connected to the receiver using the web browser can control all aspects of the receiver. Although this is the initial state, it is not the recommended mode of operation. It is recommended that a security strategy for the use of one or more accounts be put into place. The use of a security strategy protects not only against malicious attacks on receiver opeation, but also against the accidental change of critical receiver settings that can affect day-to-day operation.

The Access Controls provided on this page provide the ability to restrict access to modify various controls to selected user accounts. This affects the ability to access various web pages when using the web browser interface. When Access Controls are enabled, if access to a page is restricted, a login dialog will be presented before access to that page is granted.

EXTREMELY IMPORTANT: Once security is enabled, make sure that access to the sysadmin account, or an account with System Controls access, is available to those responsible for performing the system administration. If the password to the sysadmin account is changed, record the password in a safe place to avoid problems in accessing and modifying receiver settings at a later date. It is very important to not lose the password for the sysadmin account.

System Controls

Accounts with access to System Controls have the ability to modify the most important system settings, including the Security, Internet configuration and I/O configuration controls. Access to System Controls is required to upgrade the firmware in the receiver.

System controls are enabled by selecting the Restricted radio button, then pressing OK. Once System Controls have been restricted, only the sysadmin, or other account with System Controls access rights, will be able to make changes to the system controls.

To remove restrictions on System Controls, the sysadmin, or other account with System Controls access rights, must be used to access this page. System Controls restrictions are removed by selecting the Unrestricted radio button.

GPS Controls

Accounts with access to GPS Controls have the ability to modify the settings that affect GPS operations, including satellite tracking modes. They can also control data logging operations and delete logged data files.

GPS controls are enabled by selecting the Restricted radio button, then pressing OK. To remove restrictions on GPS Controls, select the Unrestricted radio button then press OK. The ability to enable or remove GPS Controls may be restricted by the System Controls settings.

File Access

Accounts with File Access have the ability to view, download and delete collected data files using the web browser. Although accounts with only File Access have the ability to view the settings of other receiver controls, they will not be able to change them.

File Access controls are enabled by selecting the Restricted radio button, then pressing OK. To remove restrictions on File Access, select the Unrestricted radio button then press OK. The ability to enable or remove File Access controls may be restricted by the System Controls settings.

Use the OK button to leave this page and apply the Access settings. Use the Cancel button to return to the Accounts summary page.
