Which network ports and URLs are required for the KACE SMA appliance to function? -
설명
The following table describes expected KACE Systems Management Appliance (SMA) traffic (inbound, outbound, bidirectional) at the NIC. This is meant to describe internal network behavior. Any outbound ports that require access out to the internet are labeled as 'NAT' in the Direction column. Some unique configurations, such as allowing SMTP inbound directly to the SMA will require slight deviation and custom configuration outside the confines of this list. When in doubt, contact KACE Support for clarification.

해결 방안
Quest’s patching and updating process for KACE® System Management Appliances (SMA) includes several security features. For example, Quest’s transmissions of patch and update metadata for SMA are encrypted. Checksums are used to validate the integrity of SMA patch payloads. And, the directory where SMA patch payloads reside is permission-controlled to prevent user tampering.
As with any web-server based application, security best practices include limiting access to the KACE Systems Management Appliance (SMA) from the Internet. Careful consideration and review of the environment are necessary to ensure security.
It is strongly recommended to consider firewalls, encryption, port access, roles, antivirus, SSL, access control list, disaster recovery, and review Best Practices for Securing your SMA prior to configuring the SMA on the Internet. At a minimum, if the SMA is configured as internet/public facing, only port 443 (HTTPS) traffic should be allowed inbound through a firewall to the SMA for UI access and agent communication traffic.
Port Purpose Configuration Location Optional / Required Direction Protocol 20/21 FTP to Backup Share Security Settings Optional Inbound FTP 22 SSH for KACE Support Tether Security Settings Optional Outbound/NAT SSH 25 SMTP Queue Configuration / Network Settings Optional Bidirectional TCP 80 User/Admin/System UI (non-SSL); Agent/Replication Share Downloads (non-SSL) Security Settings Required for UI/Agent traffic if SSL not enabled; Strongly recommend using SSL instead; Still required outbound/NAT for SMA itself Inbound (non-SSL);
Outbound/NAT (SMA requires HTTP for patch feed sync)
HTTP 161 SNMP Monitoring of SMA Security Settings Optional Inbound UDP 199 SNMP Read Access (SMUX) Security Settings Optional Inbound TCP 443 SSL User/Admin/System UI; Agent/Replication Share Downloads Security Settings Required if SSL is enabled Inbound (Agent/Replication Share Traffic);
Outbound/NAT (several services, including patching, rely on the ability to download to the SMA from the internet via HTTPS)
HTTPS 587 SMTPS Outbound Mail Relay Queue Configuration / Network Settings Required for email sending via SMTPS Outbound;
NAT (if using a cloud service)
TCP 110/995 POP3/SPOP Inbound Mail Queue Configuration / Network Settings Required for email retrieval via POP/SPOP Outbound;
NAT (if using a cloud service)
TCP 139/445 Access to Samba Shares/SMB (Replication Shares, Agent Provisioning (non-WinRM method)) Security Settings Both Ports Required for Provisioning (non-WinRM) Bidirectional SMB 389/636 LDAP/LDAPS LDAP Filters / LDAP Authentication Optional Outbound;
NAT (if using a cloud service)
LDAP 3306 Remote Read-Only Database Access (ODBC) Security Settings Optional Inbound TCP 5985 WinRM (HTTP/HTTPS) used for Agent Provisioning Agent Provisioning Optional Outbound HTTP/HTTPS 52231 Upgrade Status Page (temporary web server during upgrade) Not Configurable Optional Inbound HTTP/HTTPS URLs Required for Proper SMA Functionality
