SAP HANA Security Group Planning

Table 1 describes the SAP HANA security group rules.

NOTE:

The network segments and IP addresses are for reference only. The following security group rules are recommended practices. You can configure your own security group rules as needed.
In the following table, ## stands for the SAP HANA instance ID, such as 00. The instance ID must be the same as that specified during SAP HANA software installation. For details about SAP HANA instance ID planning, see SAP HANA ECS Planning.
For more information about the specific ports to be accessed by SAP software and security group rules, see SAP official documents.

**Table 1** SAP HANA security group rules
Source/Destination	Protocol	Port Range	Description
Inbound
Automatically specified by the system	All	All	Security group rule created by the system by default It enables ECSs in the same security group to communicate with each other.
0.0.0.0	TCP	22	Allows users to access the SAP HANA Studio using Secure Shell (SSH) protocol. This rule is required only when SAP HANA Studio is deployed on a Linux ECS.
0.0.0.0	TCP	3389	Allows users to access the SAP HANA Studio using Remote Desktop Protocol (RDP). This rule is required only when the SAP HANA Studio is deployed on a Windows ECS.
10.0.0.0/24	TCP	80 (HTTP)	Allows users to access the NAT server using Hypertext Transfer Protocol (HTTP).
10.0.0.0/24	TCP	443 (HTTPS)	Allows users to access the NAT server using Hypertext Transfer Protocol Secure (HTTPS).
10.0.0.0/24	TCP	1128-1129	Allows access to SAP Host Agent using SOAP/HTTP.
10.0.0.0/24	TCP	43##	Allows access to XS Engine from the 10.0.0.0/24 subnet using HTTPS.
10.0.0.0/24	TCP	80##	Allows access to XS Engine from the 10.0.0.0/24 subnet using HTTP.
10.0.0.0/24	TCP	8080	Allows Software Update Manager (SUM) to access SAP HANA using HTTP.
10.0.0.0/24	TCP	8443	Allows Software Update Manager (SUM) to access SAP HANA using HTTPS.
10.0.0.0/24	TCP	3##13	Allows SAP HANA Studio to access SAP HANA.
10.0.0.0/24	TCP	3##15	Provides ports for the service plane.
10.0.0.0/24	TCP	3##17	Provides ports for the service plane.
10.0.0.0/24	TCP	5##13	Allows SAP HANA Studio to access sapstartsrv.
Outbound
All	All	All	Security group rule created by the system by default Allows SAP HANA to access all peers.

SAP S/4HANA Security Group Planning

The security group planning needs to meet the requirements for communication between SAP nodes over the management plane and internal communication plane. You need to configure the security group together with the network department. For details about SAP's requirements for security group rules, see TCP/IP ports used by SAP applications.

You can configure the security group by referring to Table 2.

NOTE:

Plan the network segments and IP addresses based on the site requirements. The following security group rules are recommended practices. You can configure your own security group rules as needed.
In the following table, ## stands for the SAP S/4HANA instance ID, which must be consistent with the instance ID specified when the SAP S/4HANA software is installed.

**Table 2** SAP S/4HANA security group rules
Source/Destination	Protocol	Port Range	Description
Inbound
Automatically specified by the system	All	All	Security group rule created by the system by default It enables ECSs in the same security group to communicate with each other.
10.0.3.0/24	TCP	32##	Allows SAP GUI to access SAP S/4HANA.
10.0.3.0/24	TCP	36##	Message Port with profile parameter rdisp/msserv
10.0.3.0/24	TCP	5##13 ~ 5##14	Allows ASCS to access SAP application server.
10.0.3.0/24	TCP	33##, 38##, 48##	Port used by CPIC and RFC
10.0.3.0/24	TCP	22	Allows SAP S/4HANA to be accessed using SSH.
10.0.3.0/24	TCP	123	Allows other servers to synchronize time with SAP S/4HANA.
Outbound
All	All	All	Security group rule created by the system by default Allows SAP 4/HANA to access all peers.
