TCP port numbers from 0 to 1023 are universally reserved for well-known
. Never use these port numbers.
7.3 Denial of service (DOS) threshold rates
Protection of ports used for TCP/IP communication, such as Ethernet, is very important. Cybersecurity
threats can make a device unavailable for connection.
If the Totalflow device has a Denial of Service (DOS) attack, the device cannot grant requests for
connection. It stops responding. The following table provides the DOS threshold rates per packet type.
The device stops responding at these thresholds.

7.4 Security guidelines
The following table contains recommended guidelines to secure access to the XIO. Find procedures for
secure configuration throughout this manual, in Quick Start Guides, and in online PCCU help files.
Table 7-6: XIO security guidelines
Secure physical
access to the device
Control access to the device, internal components, and connected peripherals.
Secure access with
security switch
Turn the onboard security switch on to enforce authentication through bi-level
security codes or RBAC.
section 7.5.
Configure bi-level
security codes
Change default security codes to private codes (the default security code for both
level 1 and level 2 is 0000).
section 7.5.
Enable Role-Based
Access Control
(RBAC)
Configure RBAC. See section 7.6.
Enable
role-based access and enable authentication for each of the communication
he default RBAC passwords and security codes.
Secure network
connection
The device only connects to a firewall-protected private network. Do not connect
directly
to the Internet.
