As experts in the management of z/OS networks WDS understands the importance of increasing the effectiveness of standard z/OS components, such as SyslogD, FTP and Enterprise Extender (EE). SyslogD is used to record critical system events, yet facilities for managing it are limited. FTP and Enterprise Extender (EE) protocols are freely available with z/OS and provide excellent value as alternatives to proprietary data transfer solutions, in the case of ftp, or potentially having to re-write complex, legacy SNA applications to take advantage of IP networking as is the case with EE. Yet there is room for significant improvement with all three of these vital z/OS components.


While there are many ways to encrypt ftp traffic, access control is a serious issue for organizations wishing to give their users access to ftp. FTP implementation can leave business data exposed. Personnel files, patient information, payroll details and confidential corporate records can be transferred from your company, without your knowledge, and sent anywhere, shared with anyone. Files can be redistributed or modified and reinstated, with no record of it ever happening. This forces many enterprises to withhold ftp services from the user community and look to expensive alternatives.

ZEN FTP CONTROL (ZFC) restores ftp's credibility as a business tool and is the missing link for businesses looking for an inexpensive way of sharing data. ZFC plugs the holes associated with securing ftp access and turns ftp into viable alternative to the costly proprietary solutions.


IBM's Enterprise Extender (EE) protocol is part of Communications Server, which is freely available with the z/OS operating system. It was written to enable businesses to transition away from proprietary SNA networking to the open standards of IP. The attraction of EE is that it allow enterprises who have invested huge amounts of money in SNA applications, to play in the internet age. This it does by 'encapsulating' SNA applications data in IP packets. It's a great solution and negates the need for expensive re-writes of legacy applications.

The disadvantage of EE centres around its use of UDP protocol. For many experts UDP is seen as potential security hazard due to its 'connectionless' nature. Furthermore, industry standard encryption and authentication methods such as SSL or TLS cannot be applied to UDP.

ZEN EE SECURITY (ZES) overcomes these disadvantages by uniquely converting EE traffic to TCP, With ZES, preserving SNA application investment and taking advantage of IP networking no longer need to be mutually exclusive.


Syslog Daemon (SyslogD) support in ZEN extends its system and network log services to include messages originating from the SyslogD. SyslogD is a critical part of z/OS's Intrusion Detection and Prevention services (IDS) because detailed event messages, such as security violations, are sent to SyslogD, as well as messages from many other important communications services including FTP and AT-TLS. ZEN's ability to provide real-time monitoring of SyslogD is vital for z/OS system security.

ZEN Rexx procedures driven by automation on receipt of a SyslogD message can extract the message attributes (facility, priority and origin IP address) as well as the message text. All ZEN automation capabilities are available for SyslogD messages including forwarding the message to console, email, SNMP traps etc. You can see and potentially automate any SyslogD-enabled device by routing its messages to the ZEN System Log.
