6.3.1 Overview
Replace the existing first and second paragraphs with the following new text:
All traffic from uncontrolled networks is passed or processed through a 460-Gateway or 460-
Wireless gateway. A 460-Gateway consists of firewall(s) (see 6.3.2) and may include support
for one or any combination of the following functions:
• direct communication (see 6.3.3);
• DMZ with application servers (see 6.3.5.2);
• DMZ with interoperable access to file storage (see 6.3.5.3).
Firewall(s) provide network-access security for the uncontrolled network and the 460-Network.
Firewalls for external and internal interfaces may be provided by the same application.
The 460-Gateway components may be implemented in one device or in different devices.
Figure 2 shows an example of a 460-Network with a 460-Gateway.
6.3.2.1 External firewall
Replace the existing paragraph with the following new paragraph:
An external firewall blocks all traffic unless it is registered (i.e. whitelisted) and destined only
to equipment in the DMZ. This means that, in principle, all direct communication to or from a
460-Network is not allowed.
6.3.2.2 Internal firewall
Replace the existing paragraph with the following new paragraph:
An internal firewall blocks all traffic unless it is either destined to equipment in a 460-Network
and it originates from equipment in the DMZ or it is destined to equipment in the DMZ and it
originates from equipment in a 460-Network. All traffic passing through the internal firewall is
registered (i.e. whitelisted) in advance.
6.3.5.1 Firewall
Replace the existing title with the following new title:
6.3.5.1 General
Replace the existing second and third bullets with the following new bullets:
• firewall(s) shall be provided which are configured with the combination of source and
destination IP address, protocol and destination port number (see 6.3.2);
• all connections between uncontrolled networks and a 460-Network shall be registered (i.e.
all network traffic that does not match a set firewall rule shall be blocked by the firewall);

6.3.5.2 Application server
Replace the existing second paragraph with the following new paragraph:
If provided, the application server shall provide an application level authentication
mechanism, such as password, smartcard, digital signature, dongle, etc., of clients from
uncontrolled networks.
8.2.7.1 Alerts and indication
Replace, in the existing first paragraph, the existing reference "IEC 62288" with
"IEC 62923-1".
Table 2 – Summary of alert of network monitoring
Replace the existing title of the second column "Cause" with "Purpose".
Replace, in the last column, the existing unique identifiers at alert source corresponding to the
alerts listed below with the following new identifiers:
Direct connection to uncontrolled network as a caution (see 6.3.4) 3159
Direct connection to uncontrolled network as a warning (see 6.3.4) 3158
Connected to uncontrolled network (see 6.3.5.1) 3163
Network traffic capacity may be exceeded (see 8.2.2) 3166
Network traffic capacity exceeded (see 8.2.2) 3168
Network redundancy lost for xxxx (see 8.2.3) 3173
8.2.7.2 Alert management interface
Replace the existing second paragraph with the following new paragraph:
The alert management interface, if provided, shall be compliant with the sentences of Annex E
and comply with the communication requirements of IEC 62923-1 and IEC 62923-2. In the
BAM concept, the network components act as alert sources.
8.2.7.4 Remote acknowledgement and silencing of alerts
Replace the existing first paragraph with the following new paragraph:
Remote acknowledgement shall only be possible for category B alerts.
10.8.4 Firewall
Replace the existing second paragraph with the following new paragraph:
Set an EUT in accordance with the manufacturer’s instructions between a 460-Network and
an uncontrolled network. Using a network scanner with port scan function, set it to scan the
entire address range for the 460-Network, DMZ and uncontrolled network. Use packet capture
software running in promiscuous mode and confirm by analytical evaluation that packets do
not pass through the EUT from the uncontrolled network to the 460-Network and vice-versa as
follows:
• port scan UDP and TCP test for all ports 1-65535 to the internal address range of the
460-Network;
• if DMZ is provided, port scan UDP and TCP test for all ports 1-65535 to the address range
of the DMZ;
© IEC 2020
• port scan UDP and TCP test for all ports 1-65535 to the address range of the uncontrolled
network.
Example test:
®5
Using the Nmap network scanning tool with an address range for a 460-Network of
192.168.22.0/24, for a DMZ of 172.31.16.0/24 and for an uncontrolled network of
10.100.100.0/24.
• Port scan UDP and TCP test to the internal address range of the 460-Network:
complete a ping test with TCP port scan with the command "nmap -p 1-65535 -sV -sS -T4
192.168.22.0/24";
complete a ping test with UDP port scan with the command "nmap -p 1-65535 -sV -sU -T4
192.168.22.0/24".
• Port scan UDP and TCP test to the address range of the DMZ:
complete a ping test with TCP port scan with the command "nmap -p 1-65535 -sV -sS -T4
172.31.16.0/24";
complete a ping test with UDP port scan with the command "nmap -p 1-65535 -sV -sU -T4
172.31.16.0/24".
• Port scan UDP and TCP test to the address range of the uncontrolled network;
complete a ping test with TCP port scan with the command "nmap -p 1-65535 -sV -sS -T4
10.100.100.0/24";
complete a ping test with UDP port scan with the command "nmap -p 1-65535 -sV -sU -T4
10.100.100.0/24". ®
