Trusted Node Security
The Trusted Node Security feature enables you to enforce more restrictive security parameters when dealing with specific nodes in your network, enabling you to define each adjacent node in the network map as internal or external in its relationship to the local node of that network map.
When a Process begins execution, the security exit gets control and a bit in the Security Control Block (SQCB), SQEXTNOD, turns on if the adjacent node is defined as EXTERNAL. If the adjacent node is defined as INTERNAL, the bit turns off. Based on this information, the administrator can code the security exit to take the appropriate action.
In the adjacent node definition, the fifth positional parameter is required for the Trusted Node Security option. The parameter description follows:
Parameter | Description |
---|---|
EXTERNAL|EXT | Indicates that the node is external. |
INTERNAL|INT | Indicates that the node is internal. This value is the default. |
