Product Details
SSSS (Simplex Security Software Solution)
SSSS is a one-way security solution that transfers security area
data and files from national security facilities/public
institutions to non-security areas.
Only the data in the security zone that is allowed by the
administrator is securely encrypted and sent to the non-security
zone, and the data that is not allowed is blocked from being
transmitted to prevent data leakage.
It also blocks all data transmitted from a non-secure area to a
secure area, preventing outside intrusion.
Configurations
① SSSS Tx v3.0 :
Located in a secure area, it is designed to block all packets by
default and allow only communication with IPs allowed by the
network policy, and acquires data from the FTPS server according
to the settings registered in the FTPS policy and sends it to the
SSSS Rx within the non-secure area.
② SSSS Rx v3.0 :
The 'SSSS RX' located in a non-secure area receives 'FTPS data'
from 'SSSS Tx' and is sent to the FTPS server.
③ SSSS Manager v3.0 :
Displays audit logs (network logs, accounting logs, system logs)
and provides operational settings for SSSS (access policy, FTPS
policy, manager settings, server settings, log settings, DBMS
settings, mail settings, etc.) and provides a user GUI.
