Workload Security components communicate over your network using the following:
Before deployment, your network administrator might need to configure firewalls, AWS
security groups, and web proxies to allow those network services.
Default settings are displayed. Many network settings are configurable. For example,
if your network has a web proxy, you could configure agents to connect through it on port 1443, instead of directly
to Workload Security on port 443. If you change the default settings, then firewalls
must allow communications via the new settings.
The following network diagram provides an overview:

Required Workload Security IP addresses and port numbers
The following table is organized by source address (the deployment component which
starts the TCP connection or UDP session). Replies (packets in the same connection
but opposite direction, from the destination address) usually must be allowed, too.
Workload Security servers usually have dynamic IP addresses (that is, other computers
in your deployment use DNS queries to find the current IP address of a Workload Security
FQDN when required). For the list of Workload Security domain names, see Required Workload Security URLs.
Some ports are required only if you use specific components and features. Some services
might have static IP addresses. These exceptions and optional features are indicated.
All ports in the table are destination ports (also known as listening ports). Like
many software,
Workload Security also uses a range of dynamic, ephemeral source ports when opening
a socket. Rarely, ephemeral source ports might be blocked, which causes connectivity issues. If that happens, you must also open the source
ports.

Only configure if the server's other software uses the same port
(a port conflict), or if host firewalls such as iptables
or Windows Firewall block localhost connections (server
connecting internally to itself). Network firewalls do
not need to allow this port because localhost
connections do not reach the network.

Required Workload Security URLs
Web proxies and URL filters can inspect the HTTP layer of connections: valid
certificates, URL (such as
/index
), fully-qualified domain name
(FQDN) (such as Host: store.example.com:8080
), and more. Allow all
URLs on every FQDN listed in the following table.For example, agents and relays must be able to download software updates from
files.trendmicro.com
on port 80 or 443. You have allowed that
TCP/IP connection on your firewall. However, the connection contains the HTTP
or
HTTPS protocol, which can be blocked not only by firewalls, but also by web proxies
and web filters. Therefore you must configure them to allow
https://files.trendmicro.com/
or
http://files.trendmicro.com/
and all sub-URLs.Some FQDNs are required only if you use specific components and features, as
indicated.
