Example of conversation level security

As shown in this example, to set up a successful security system for use with the Server Option in an IMS TM LU 6.2 environment, you need to synchronize SNA and IMS TM very carefully.

1. At the mainframe, go to the SNA LogMode entry.

2. Define security as “VERIFY,” which requires a user ID and password. This example highlights security defined as VERIFY:

   SYBTABV		MODETAB
    		EJECT
    		TITLE 'M6P1024V'
    *------------------------------------------------------------*
    * LU6.2,	SINGLE SESSIONS, RU_SIZE(1024),
    * SYNCH_LEVEL(CONFIRM), SECURITY(VERIFY) 
    *------------------------------------------------------------*
    M6P1024V		MODEENT LOGMODE=M6S1024V,FMPROF=X'13',TSPROF=X'07',
    		PRIPROT=X'B0',SECPROT=X'B0',COMPROT=X'78A5', 
    		RUSIZES=X'8787',TYPE=X'00', 
    		PSNDPAC=X'05',SRCVPAC=X'05',SSNDPAC=X'05',
    		PSERVIC=X'060200000000000000102F00'
   

   *MODEEND
   
   

   The 10th byte of the PSERVIC parameter must be set to x’10’ for “VERIFY” security.

3. In your network definition to SNA, specify the mode you defined in the LogMode entry. You can apply the LogMode entry to a specific LU statement, or apply it globally through the PU statement:

   SYBPU1		PU	CUADDR=041,DLOGMOD=M6P1024V,MAXBFRU=11,SSCPFM=FSS, +
    			USSTAB=ISTINCDT,DELAY=0,SECNET=YES,ISTATUS=ACTIVE        
   

   * 
    SYBLU02		LU 	LOCADDR=2
