SECTION 1.3 SERVICE SECURITY CONSIDERATIONS
Item 1 Default use of Non-Standard Ports
Use of Non-Standard ports help ensure consistency in an environment where UPnP, and customer port forwarding,
may re-map standard ports for personal use.
The following ports are used as VisionNet defaults:
Service LAN Port / Status WAN Port - Status
HTTP 80 - Enabled 6080 - Enabled
TELNET 23 - Enabled 6023 - Disabled
SSH 22 - Enabled 6022 - Enabled
FTP 21 - Disabled 21 - Disabled
TFTP 69 - Enabled 69 - Disabled
ICMP N/A - Enabled N/A - Enabled
SNMP 161 - Disabled 161 - Disabled
SAMBA 445 - Enabled N/A
Item 2 WAN Interface Restrictions
Dedicated PVC / VLANs are an effective method of isolating management services to privately managed
networks; thus removing potential security threats.
IP based ACLs are suggested for public facing WAN services.
