| Practice | Reason | |----------|--------| | Isolate FTP in a separate VLAN | Prevent unauthorized access to PLC control network | | Use FTPS (port 990) or SFTP (not FTP) | Credentials & data travel encrypted | | Change default root directory | Avoid system access | | Disable anonymous login | Mandatory for industrial security | | Limit simultaneous connections | Prevent DoS | | Log all FTP transfers | Audit trail for safety systems | | Use watchdog to restart FTP server if hung | CP internal or external monitoring |
ICC stands for several possibilities in industrial and technical environments. The most relevant for this keyword are:
| Acronym | Full Form | Likelihood | |--------|-----------|-------------| | ICC | Industrial Control Computer | High – often embedded systems with FTP servers for log retrieval. | | ICC | Intelligent Communication Controller | Medium – used in substation automation (IEC 61850). | | ICC | International Code Council | Low – unrelated to FTP servers. | | ICC | ICC (brand) – e.g., ICC Building Automation Systems (CAREL, Distech) | High – many BMS controllers use FTP for firmware updates. |
Most plausible: An ICC-branded building automation controller (e.g., ICC’s “Intelligent Room Controller” or “Universal I/O Controller”) with an embedded FTP service for configuration backup and trend data export. 10.16 1oo 244 icc ftp server
The combination of safety logic (1oo) and cleartext FTP is a red flag for any OT (Operational Technology) security assessment.
Based on the deconstruction, here is the most probable real-world scenario:
System: An ICC-branded industrial safety controller or protocol gateway. Model Series: Possibly the ICC
1oo244series (a safety-rated logic solver with 244 I/O points). Network Assignment: Static IP address10.16.1.244(the1oobeing a mis-parsed separator). Service Enabled: An embedded FTP server running on port 21 (or a non-standard port for obscurity). Function: The FTP server allows engineers to retrieve fault records, update the 1oo2/1oo244 voting logic, or access trend data from the field devices. | Practice | Reason | |----------|--------| | Isolate
ftp> put new_firmware.bin /firmware/update.bin
Warning: Uploading to an industrial device can disrupt operations. Do this only during planned maintenance.
The string 10.16 1oo 244 likely means 10.16.1.244. Try:
ping 10.16.1.244
If that fails, the 1oo might be literal; check 10.16.100.244 or 10.16.1.100. ICC stands for several possibilities in industrial and
FTP sends usernames, passwords, and files in clear text. Anyone with Wireshark on the same network segment can capture credentials for 10.16.100.244.
From a PC on same network:
ftp 192.168.1.10
User: oper
Password: ******
ftp> ls
ftp> put test.txt
ftp> get /DATA/CSV_OUT/meas_01.csv
Repeat for 192.168.1.11.
