4. SAIG Security TDClient v2.2.x (formerly EasyAccess) is the client software used to send and receive FTP data transmissions securely over the Internet using SSL 3.0 and the Diffie-Hellman Dynamic Key Exchange algorithm. TDClient v2.2.x (formerly EasyAccess) is the client software used to send and receive FTP data transmissions securely over the Internet using SSL 3.0 and the Diffie-Hellman Dynamic Key Exchange algorithm. Since TDClient is built into current versions of EDConnect, the level of security is identical between EDConnect and TDClient running on a mainframe. Since TDClient is built into current versions of EDConnect, the level of security is identical between EDConnect and TDClient running on a mainframe.

7. CSU Process Overview Receiving Message Classes Receiving Message Classes –1 st job in nightly production schedule –Establish secure connection to SAIG –Download available message classes Only those we have identified Only those we have identified –Decompress –Backup message classes –Move message classes to appropriate datasets Available for subsequent jobs during the same nightly run Available for subsequent jobs during the same nightly run –If a downloaded message class is a COMRECOP: The same “receive” JCL initiates CASX50 The same “receive” JCL initiates CASX50 –XML documents are parsed and datasets created  ORSPx, DRSPx, PNOTEx, etc. TDClient

8. CSU Process Overview Sending Message Classes Sending Message Classes –Production job runs generating an outbound message class –Establish secure connection to SAIG –Message class is compressed –Message class is sent TDClient

EDIPDS – Temporary location of the send file to be compressed EDIPDS – Temporary location of the send file to be compressed EASTATUS – Contains any errors during send or receive sessions EASTATUS – Contains any errors during send or receive sessions DCMPLOG – Logs decompression step for each file received. Indicates if any files failed decompression DCMPLOG – Logs decompression step for each file received. Indicates if any files failed decompression SECFILEX – This name comes from the “SECFILE=DD” in the TRANSFER statement. It stores the SECFILE command lines that tell EasyAccess how to format the headers and trailers during compression/decompression SECFILEX – This name comes from the “SECFILE=DD” in the TRANSFER statement. It stores the SECFILE command lines that tell EasyAccess how to format the headers and trailers during compression/decompression OUTMSG – Confirms successful OUTMSG – Confirms successful –Login, compression, and send of file or –Decompression and receive files SYSPRINT – Logs the stored Transfer processing SYSPRINT – Logs the stored Transfer processing EAFTPLOG – Verifies success or failure of logging on to system and send/receive of files as identified by unique filename. Logs all internal and external FTP activities EAFTPLOG – Verifies success or failure of logging on to system and send/receive of files as identified by unique filename. Logs all internal and external FTP activities EALOG – General log of the session EALOG – General log of the session EXFERLOG – Verifies all internal FTP, compression, and decompression activities EXFERLOG – Verifies all internal FTP, compression, and decompression activities COMPLOG – Verifies successful compression of data COMPLOG – Verifies successful compression of data
