This document introduces EntireX Security under z/VSE through overviews of the functionality and components of EntireX Security. The location where Broker Kernel is installed determines the functionality made available for EntireX Security. This document covers the following topics:

Note:
Installation of the security software is described under Installing EntireX Security under z/VSE.


Introduction

Functionality of EntireX Security

This table lists the security functionality available with EntireX Security running Broker Kernel under the respective operating system. See also Configuration Options for Broker.

Security Functionality z/OS UNIX Windows BS2000/OSD z/VSE Comment
Authentication of user Yes Yes Yes Yes Yes Verify User ID password.
User password change Yes No No No No  
LDAP authentication No Yes Yes No No Authenticate using LDAP repository.
Trusted user ID Yes No No No No Trusted computer base, avoiding plain text password.
Verified client user ID Yes No No Yes Yes Provide verified identity of client to server.
Authorization of client request Yes No No No No  
Authorization of server register Yes No No No No  
Authorize IP connection Yes No No No No

EntireX Security for EntireX Broker

EntireX Broker acts as an agent to make the creation and operation of client/server applications simpler and more effective. Any number of server applications can be built for use by any number of clients. EntireX Security allows you to protect your server applications and clients independently.

Clients and servers are authenticated by user ID and password on their first contact with the system.

Configuration Options for Broker

This section describes the parameters for configuring EntireX Security under z/VSE. You may either accept or modify the default settings which are specified in the Broker attribute file DEFAULTS=SECURITY. See also Security-specific Attributes under Broker Attributes and Operator Commands.

This section covers the following topics:

Authentication

Authentication is mandatory and performed for both client and server applications based on user ID and password. First contact with the Broker results in the host security system being referenced. If authentication fails, access is denied and the application is informed with a suitable error message.

It is the responsibility of both client and server applications to supply a valid user ID and password when calling the Broker. The user ID must be supplied with all commands. The password is required only for the first command and should not be supplied subsequently, except when executing multiple instances of the same application.

Authentication expires after a period of non-activity after which it must be repeated. User ID and password must be resupplied before further access is possible. The time limits CLIENT-NONACT and SERVER-NONACT determine these timeout periods and are defined in the Broker attribute file.

Guaranteed Encryption / Decryption Mechanism

EntireX Security ensures message encryption consistency regardless of any configuration errors. This means that if the relevant assembly parameters or environment variables are incorrectly or inconsistently specified, the integrity of the Broker message is honored. This feature requires upgrade of all EntireX Security Broker stub and kernel components in all places.

See Broker attribute ENCRYPTION-LEVEL and control block field ENCRYPTION-LEVEL.

Password to Uppercase

To cater for situations where a site is in transition from uppercase to mixed case passwords setting this parameter can convert all passwords to uppercase. It is not recommended you use this option by default.

PASSWORD-TO-UPPER-CASE={NO,YES} Convert password to uppercase.

Security Level

By default, EntireX Security furnishes authentication with optional encryption of send/receive buffers. The following parameter can be used to modify the functionality of EntireX Security:

SECURITY-LEVEL=ENCRYPTION No authentication or authorization checks performed. The only functionality available in this mode is message privacy.
SECURITY-LEVEL=AUTHENTICATION User authentication is performed but without any resource authorization (the normal default operation).
