HOST Class

Each record in the HOST class defines the access that a host has to the local computer connected by IPv4.

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

CA ControlMinder resolves the addresses of host names that you add to the HOST class. This means that the names mustmust appear in the operating system hosts file, or must be defined to NIS or DNS.

For each HOST record, the INETACL property defines the services the local host can provide to that host.

CA ControlMinder permits aliases for a host name, but records that represent aliases are not used for authorization checks. You must know the canonical name of a host for CA ControlMinder to protect the connection with that host.

CA ControlMinder resolves a hostname by one IP address. If multiple IP addresses are configured for one hostname, then use one of the following classes:

The key of the HOST class record is the name of the host.

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. Nonmodifiable 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

The list of GHOST or CONTAINER records a resource record belongs to.

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

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.
