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 ACF2 Data Collection and Data Set and Resource Data Collection: - ACF2CMDS.RPT(ACFGSO) - 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) Programs TFTPD and EZATD are defined in the GSO PPGM record. 2) Program resources TFTPD and EZATD are defined in the PROGRAM resource class. 3) No access to the program resources TFTPD and EZATD is permitted. c) If all items in (b) are true, there is NO FINDING. d) If any item (b) is untrue, this is a FINDING.
The IAO will ensure that the resource controls for the TFTP Server programs TFTPD and EZATD and ensure all access is restricted. Evaluate the impact of implementing the following change. Develop a plan of action and implement the change as required. 1) Ensure that the resource controls for the TFTP Server programs TFTPD and EZATD and ensure all access is restricted. Examples: SET CONTROL(GSO) CHANGE PPGM PGM-MASK(TFTPD EZATD) ADD F ACF2,REFRESH(PPGM) $KEY(TFTPD) TYPE(PGM) UID(*) PREVENT SET R(PGM) COMPILE 'ACF2.MVA.PGM(TFTPD)' STORE F ACF2,REBUILD(PGM) $KEY(EZATD) TYPE(PGM) UID(*) PREVENT SET R(PGM) COMPILE 'ACF2.MVA.PGM(EZATD)' STORE F ACF2,REBUILD(PGM)
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.
