2.1.3 Data Integrity

All records are protected using the symmetry encryption and checksum

algorithms. Symmetry encryption protects the data privacy. With check-

sum, which is protected by encryption, we could guarantee the integrity

of data. Transmissions also include a sequence number, which is pro-

tected by encryption, so that missing, altered or extra messages are

detectable.

2.1.4 Access Control and Local Password Configuration

IP access control can block users from unauthorized hosts; it only allows

32 users to access at one time. In addition, the ADAM-4570S/4571S pro-

tects all configuration settings from being changed inadvertently. When

this option is enabled, only the corresponding PC can configure the mod-

ule. The multiple security mechanisms work to prevent unauthorized

access to your RS-422/485 networks.
