HOSTNET Class

Each record in the HOSTNET class defines a group of hosts on a particular network. HOSTNET records define rules that govern the access other hosts in the group have to the local host when using IPv4 communication.

Note: CA ControlMinder access rules for IP communication apply only to IPv4. CA ControlMinder does not control access by IPv6.

The INMASKMATCH determines which other hosts are subject to a HOSTNET record. The INETACL property defines which services the local host can provide to those hosts.

The key of the HOSTNET class record is the name of the HOSTNET record.

The following definitions describe the properties contained in this class record. Most properties are modifiable and can be manipulated using selang or the administration interfaces. Non-modifiable properties are marked informational.

CALENDAR

Represents a Unicenter TNG calendar object for user, group, and resource restrictions in CA ControlMinder. CA ControlMinder fetches Unicenter TNG active calendars at specified time intervals.

COMMENT

Defines additional information that you want to include in the record. CA ControlMinder does not use this information for authorization.

Limit: 255 characters.

CREATE_TIME

(Informational) Displays the date and time when the record was created.

DAYTIME

Defines the day and time restrictions that govern when an accessor can access a resource.

Use the restrictions parameter with the chres, ch[x]usr, or ch[x]grp commands to modify this property.

The resolution of daytime restrictions is one minute.

GROUPS

Defines the list of CONTAINER records that a resource record belongs to.

To modify this property in a class record, change the MEMBERS property in the appropriate CONTAINER record.

Use the mem+ or mem‑ parameter with the chres, editres or newres command to modify this property.

INETACL

Defines the services the local host is allowed to provide to the group of client hosts and what their access types are. Each element in the access control list contains the following information:

Services reference

A reference to a service (a port number or name). To specify all the services, enter an asterisk (*) as the services reference.

CA ControlMinder supports dynamic port names as specified in the /etc/rpc file (for UNIX) or \etc\rpc file (for Windows).

Access

Defines the access authority that the accessor has to the resource.

Use the access(typeofaccess), service, and stationName parameters with the authorize[-] command to modify accessors and their access types in the INETACL property.

INSERVRNGE

Specifies the range of services that the local host provides to the group of client hosts.

Performs a similar function to the INETACL property.

Use the service(serviceRange) parameter with the authorize[-] command to modify accessors and their access types in the INSERVRANGE property.

INMASKMATCH

Defines the group of hosts to which this HOSTNET record applies. The property contains mask and match values, which are applied to the IP address of the requesting host to determine whether the requesting host belongs to the group.

The INMASKMATCH property only supports addresses that are in IPv4 format .

Note: This property corresponds to the mask and match parameters of the chres command.

OWNER

Defines the user or group that owns the record.

RAUDIT

Defines the types of access events that CA ControlMinder records in the audit log. RAUDIT derives its name from Resource AUDIT. Valid values are:

all

All access requests.

success

Granted access requests.

failure

Denied access requests (default).

none

No access requests.

CA ControlMinder records events on each attempted access to a resource, and does not record whether the access rules were applied directly to the resource, or were applied to a group or class that had the resource as a member.

Use the audit parameter of the chres and chfile commands to modify the audit mode.

UPDATE_TIME

(Informational) Displays the date and time when the record was last modified.

UPDATE_WHO

(Informational) Displays the administrator who performed the update.

WARNING

Specifies whether Warning mode is enabled. When Warning mode is enabled on a resource, all access requests to the resource are granted, and if an access request violates an access rule, a record is written to the audit log.
