One Identity Safeguard for Privileged Sessions 7.4

The channel policy lists the channels (for example, terminal session and SCP in SSH, Drawing, Clipboard in RDP) that can be used in a connection. The channel policy can further restrict access to each channel based on the IP address of the client or the server, a user list, user group, or a time policy. For example, all clients may access the servers defined in a connection via SSH terminal, but the channel policy may restrict SCP access only to a single client. The policies set in the channel policy are checked when the user attempts to open a particular channel type in the connection.

Channel policies are protocol specific. To list the available Channel policies for a protocol, use the following command.

curl --cookie cookies https://<IP-address-of-SPS>/api/configuration/<http|ica|rdp|ssh|telnet|vnc>/channel_policies

The following sections detail the properties of Channel policy objects.

Cookies

Cookie name	Description	Required	Values
session_id	Contains the authentication token of the user	Required	The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For more information on authentication, see Authenticate to the SPS REST API. NOTE: This session ID refers to the connection between the REST client and the SPS REST API. It is not related to the sessions that SPS records (and which also have a session ID, but in a different format).

Element		Type	Description
name		string	Top level element, the name of the object. This name is also displayed on the SPS web interface. It cannot contain whitespace.
rules		list of JSON objects	Top level element, contains the configuration properties of the object.
	actions	JSON object	The actions that SPS performs for the channel, for example, recording the traffic into an audit trail.
	allowed_for	JSON object	Specifies the access control rules of the channel, for example, permitted target IP addresses or usergroups.
	channel	string	The type of the channel. Note that channels are protocol specific, and different type of channels can have different parameters. For details on HTTP-specific channels, see HTTP channels. For details on Citrix ICA-specific channels, see ICA channels. For details on RDP-specific channels, see RDP channels. For details on SSH-specific channels, see SSH channels. For details on Telnet-specific channels, see Telnet channels. For example: "channel": "#drawing",

Element		Type	Description
actions		JSON object	The list of actions to perform when the Content policy matches the analyzed traffic. All actions are boolean values (true or false)
	audit	boolean	Set to true to record the activities of the channel into audit trails. Possible values: true or false
	content_policy	JSON object	Specifies the Content policy to use in the channel, otherwise its value is null (which is the default). For details on Content policies, see Real-time content monitoring with Content Policies For example: "content_policy": { "key": "<object-id>", }
	four_eyes	boolean	Set to true to require four-eyes authorization to access the channel. For details, see "Configuring four-eyes authorization" in the Administration Guide. Possible values: true or false

Element		Type	Description
allowed_for		JSON object	Specifies the access control rules of the channel.
	clients	list	To restrict the availability of the channel only to certain clients, list the IP address or network of the clients allowed to use this the channel. For IPv6 addresses, use the canonized format of the address. For example: "clients": [ "192.168.1.1/24", "2001:db8:85a3::8a2e:0:0/32" Alternatively, you can also enter a hostname instead. One Identity Safeguard for Privileged Sessions (SPS) saves the hostname and resolves it when opening channels, therefore SPS can trace dynamic IP addresses. NOTE: Note the following limitations: The Domain Name Servers you set must be able to resolve the hostnames you enter into the clients and servers fields, otherwise this function (and, therefore, the sessions using this Channel Policy) will not work. SPS Channel Policies support wildcard characters in the *.example.com format. If the channel opening request contains an IP address, SPS uses a reverse lookup method to resolve this IP address into a hostname for a match. SPS uses the Domain Name Servers set in the /api/configuration/network/dns endpoint to resolve the hostnames.
	gateway_groups	list	You can control channel access during gateway authentication with blacklists or whitelists of user groups. You can use local user lists on SPS, or LDAP groups. To use this option, you must also configure web gateway authentication in the connection policy, or client-side gateway authentication back-end in the authentication policy. For example: "gateway_groups": ["group1", "group2"], To configure local user lists, see User lists.
	remote_groups	list	You can control channel access during authentication to the remote server with blacklists or whitelists of user groups. You can use local user lists on SPS, or LDAP groups. For example: "remote_groups": ["group1", "group2"], To configure local user lists, see User lists.
	servers	list	To restrict the availability of the channel only to certain servers, list the IP address or network of the servers that your clients are allowed to access using this the channel. For IPv6 addresses, use the canonized format of the address. For example: "servers": [ "192.168.1.1/24", "2001:db8:85a3::8a2e:0:0/32" Alternatively, you can also enter a hostname instead. One Identity Safeguard for Privileged Sessions (SPS) saves the hostname and resolves it when opening channels, therefore SPS can trace dynamic IP addresses. NOTE: Note the following limitations: The Domain Name Servers you set must be able to resolve the hostnames you enter into the clients and servers fields, otherwise this function (and, therefore, the sessions using this Channel Policy) will not work. SPS Channel Policies support wildcard characters in the *.example.com format. If the channel opening request contains an IP address, SPS uses a reverse lookup method to resolve this IP address into a hostname for a match. SPS uses the Domain Name Servers set in the /api/configuration/network/dns endpoint to resolve the hostnames. Alternatively, you can configure a custom DNS server to be used for target selection custom_dns field of the Connection Policy.
	time_policy	JSON object	Specifies the Time policy to use in the channel. If you do not want to restrict access, use the default 7x24 policy-100. For details on Time policies, see Time policy. For example: "time_policy": { "key": "-100", }

Archive/Cleanup policy

Archiving transfers data from SPS to an external storage solution, cleanup removes (deletes) old files. Archived data can be accessed and searched, but cannot be restored (moved back) to the SPS appliance. Only those closed audit-trail files are archived where the retention time has already elapsed. To list the available Archive policies, use the following command.

curl --cookie cookies https://<IP-address-of-SPS>/api/configuration/policies/archive_cleanup_policies/

The following sections detail the properties of Archive/Cleanup policy objects.

	type	string (all \| errors-only \| none)	all: Sends notification emails on all archive-related events. errors-only: Sends notification emails only on archive-related errors. none: Sends no archive-related notification emails.
	send_filelist	boolean	This is meaningful only if notification_event is set to all. True if the list of files are included in the notification e-mail.
	file_count_limit	integer	This is meaningful only if notification_event is set to all and send_filelist is set to True. The maximum number of files that are included in the notification e-mail.
target		Top level element	Defines the address of the archive server, which protocol to use to access it, and other parameters. SPS can be configured to use the SMB/CIFS, and NFS protocols to access the archive server.
	type	string (smb \| nfs \| none)	smb: Move data to a remote server using SMB/CIFS nfs: Move data to a remote server using NFS none: Cleanup data. Data is deleted from SPS forever and cannot be recovered.
	server	Top level element
	domain	string	Only if type is set to smb. The domain name of the target server
	protocol_version	string	Only if type is set to smb. The SMB protocol to use when SPS connects to the server. Servers are usually backwards compatible with earlier protocol versions (for example, a server that supports version 2.1 supports versions 2.0 and 1.0 as well).
	share	string	Only if type is set to smb. The name and directory path of the share in the following format: share_name/path/to/directory
	authentication	Top level element	Only if type is set to smb.
	path	string	The path to the archive directory on the target server
start_times		list of strings	The time when the archive process starts in H:MM or HH:MM format.
template		string	SPS organizes the audit trails into directories based on the date or the protocol. The subdirectories are created directly into the archive directory. The following subdirectory structures are possible: PROTOCOL/CONNECTION/ARCHIVEDATE/ ARCHIVEDATE/CONNECTION/PROTOCOL/ CONNECTIONDATE/PROTOCOL/CONNECTION/ ARCHIVEDATE/ CONNECTIONDATE/
retention_days		integer (days)	Data older than this value is archived to the external server. The archived data is deleted from SPS.

Elements of server		Type	Description
server		Top level element
	selection	string (ip \| fqdn)	ip: IP address fqdn: Hostname
	value	string	The IP address or the hostname of the remote server

Elements of authentication		Type	Description
