Section 5. Overview
85
• Set AES-128 PakBus encryption key
•
Set .csipasswd file for securing HTTP and web API
•
Track signatures
• Encrypt program files if they contain sensitive information
•
Hide program files for extra protection
•
Secure the physical CR800 and power supply under lock and key
Note All security features can be subverted through physical access to
the CR800. If absolute security is a requirement, the physical CR800 must
be kept in a secure location.

(p. 580)
The CR800 and most of its peripherals must be protected from moisture. Moisture
in the electronics will seriously damage, and probably render un-repairable, the
CR800. Water can come in liquid form from flooding or sprinkler irrigation, but
most often it comes as condensation. In most cases, protection from water is
easily accomplished by placing the CR800 in a weather-tight enclosure with
desiccant and by elevating the enclosure above the ground. The CR800 is shipped
with internal desiccant packs to reduce humidity. Desiccant in enclosures should
be changed periodically.
Note
Do not completely seal the enclosure if lead acid batteries are
present; hydrogen gas generated by the batteries may build up to an
explosive concentration.
5.9.2 Protection from Voltage Transients — Overview
The CR800 must be grounded to minimize the risk of damage by voltage
transients associated with power surges and lightning-induced transients. Earth
grounding is required to form a complete circuit for voltage clamping devices
internal to the CR800.
