"Plain old" FTP on z/OS does not support encryption --- directly -- however it's possible to enforce encryption at the TCPIP stack level via AT/TLS. Short for Application Transparent Transport Level Security - the key phrase bei8ng "Application Transparent". When configured properly TCPIP itself will ensure and enforce encryption and the zOS FTP server won't even know it's happening. Interestingly enough, both client and server on z/VM do support TLS encryption.
Configuring ATTLS on zOS requires running the policy agent (PAGENT) and setting up the appropriate policies, certificates, etc. -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Bob Bridges Sent: Monday, September 16, 2024 1:50 PM To: [email protected] Subject: Is z/OS FTP encrypted? Newbie question: I've just started work for a new client, and they (understandably) don't care for me using Win FTP to load up my REXX tools because it's not encrypted; the REXX execs aren't secret, but my ID and password should be. But once I've laboriously gotten a bunch of things uploaded using IND$FILE, what about moving them from one complex to another? Is FTP encrypted once I'm talking between two mainframes? --- Bob Bridges, [email protected], cell 336 382-7313 /* ...in February, United States coalition-building efforts are dealt a severe blow when France announces that it will not participate in the impending Iraq invasion, a decision that, in the words of Defense Secretary Donald Rumsfeld, "could seriously impair our ability to surrender". -Dave Barry’s 2003 Year in Review */ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
