WMQ Recommendations.
11 January 2017 Issue 1.0
WMQ 5.3 SSL
SSL
SSL
WMQ SSL supports TCP/IP
WMQ Reuses Secret Key for life of channel
WMQ is link level security
Data on Xmit Queue and local queues is in plaintext
WMQ SSL is LINK LEVEL SECURITY – good for WMQ clients

Released by US Administration mid September 2002.

Key Recommendations:
CEO’s should consider forming security councils to integrate
cyber security, privacy, physical security and operational
considerations.
Boards should consider forming committees on IT security and
should ensure that the CEO regularly reviews
recommendations of the chief information security official.
IT continuity plans should be regularly reviewed and
exercised, and should consider site and staff alternatives.
Consideration should be given to diversity in IT service
providers.
Corporations should consider active involvement in industry
wide programs to develop IT security best practices.
Companies should review mainframe security software and
procedures, and consider developing a partnership to review
and update best practices.

Certificates
 Windows



Makecert – only if you have W2K SDK.
OpenSSL – Need to download and compile – no GUI
iKeyMan – Only end user certificates – free download.
 Mainframe

RACF – End user AND CA Certificates
 Issues


PKCS#12 – Keys only as strong as the password.
MQ5.3 Bug importing through GUI – use amqscert
 CRL’s



LDAP
OCSP
Cipherspec
 MD5 or SHA-1, RC2, RC4, DES, T-DES, RC5, RC6, AES

Application Level Security
 If the message does not itself contain a certificate and is
encrypted, you can NEVER be sure of it’s integrity or origin.
One “Mistake” is all it takes to undo Link level security.
 Application Level Security provides this capability.
 Managed at the API level – BEFORE MQPut and AFTER MQGet
or through API Crossing Exits (MQ5.3)
 Crossing Exits have performance ‘baggage’.
 API level means that you do NOT need WMQ…
 E.g. “Mangle This”, “Unmangle This”
 Means that it works with OTHER artifacts – e.g.
 Tibco, SeeBeyond, WAS, WMQI, WebLogic, etc etc
 Can use before “READ” and “WRITE” for files…
 PathWAI Secure compliments both SSL and TAMBI
