Portscan
The PortScan function allows the cyclic or manual searching for all
open, incoming TCP and UDP listen ports on the system. All ports
found are compared with whitelists. If the control finds a non-listed
port it shows a corresponding pop-up window.
The HEROS menu Diagnostic menu contains the Portscan and
Portscan OEM applications for this purpose. Portscan OEM is only
executable after entering the machine manufacturer password.
The Portscan function searches for all open, incoming TCP and UDP
ports on the system and compares them to four whitelists stored in
the system:
System-internal whitelists /etc/sysconfig/portscan-whitelist.cfg
and /mnt/sys/etc/sysconfig/portscan-whitelist.cfg
Whitelist for ports for machine manufacturer-specific functions,
e.g. for Python applications, external applications: /mnt/plc/etc/
sysconfig/portscan-whitelist.cfg
Whitelist for ports with customer-specific functions: /mnt/tnc/
etc/sysconfig/portscan-whitelist.cfg
For each entry, the whitelist specifies the type of port (TCP/UDP),
the port number, the providing program, and optional comments.
If the automatic port scan function is active, only ports listed in
the whitelists can be open. Non-listed ports trigger a notification
window.
The result of the scan is saved to a log file (LOG:/portscan/scanlog
and LOG:/portscan/scanlogevil) and, if new ports are found that are
not listed in one of the whitelists, these are displayed.
