The Trivial File Transfer Protocol (TFTP) Server, known as tftpd, supports file transfer according to the industry standard Trivial File Transfer Protocol. The TFTP Server does not perform any user identification or authentication, allowing any client to connect to the TFTP Server. Due to this lack of security, the TFTP Server will not be used. Failure to restrict the use of the TFTP Server may result in unauthorized access to the host. This exposure may impact the integrity, availability, and privacy of application data.
a) Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(PROGRAM) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(IFTP0090) b) Ensure the following program controls are in effect for the TFTP Server: 1) Program resources TFTPD and EZATD are defined to the PROGRAM resource class with a UACC(NONE). The library name where these programs are located is SYS1.TCPIP.SEZALOAD. 2) No access to the program resources TFTPD and EZATD is permitted. c) If both the items in (b) are true, there is NO FINDING. d) If any item in (b) is untrue, this is a FINDING.
Evaluate the impact of implementing the following change. Develop a plan of action and implement the change as required. 1) Ensure that the EZATD program and its alias TFTPD are defined to RACF, no access is granted, and WARN mode is not enabled. The following commands provide a sample of how this can be accomplished. rdef program tftpd addmem('sys1.tcpip.sezaload'//nopadchk) - data('Reference SRR PDI # IFTP0090') - audit(all(read)) uacc(none) owner(admin) rdef program ezatd - addmem('sys1.tcpip.sezaload'//nopadchk) - data('Reference SRR PDI # IFTP0090') - audit(all(read)) uacc(none) owner(admin) A PROGRAM class refresh will be necessary and can be accomplished with the command: setr when(program) refresh
Lavender hyperlinks in small type off to the right (of CSS
class id, if you view the page source) point to
globally unique URIs for each document and item. Copy the
link location and paste anywhere you need to talk
unambiguously about these things.
You can obtain data about documents and items in other
formats. Simply provide an HTTP header Accept:
