Portscan
The PortScan function enables the cyclic or manual searching for
all open, incoming TCP and UDP list 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
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 with machine manufacturer-specific
functions, e.g. for Python and DNC 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 contains the type of port (TCP/UDP),
the port number, the offering 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.
