5.1
Cybersecurity definition
Cybersecurity aims to secure the properties of the organization against security
risks. To strengthen the system and increase the security level towards any
cybersecurity attacks from the Internet, certain actions are recommended while
configuring the device.
• The device should be installed physically secure, for example, in a locked cabinet.
• The latest security updates need to be installed for all network devices.
• The network inventory needs to be documented and kept up to date.
• Unused services and interfaces should always be disabled.
• Only VPN connections should be used to access remote networks.
5.2

• Use pin code in SIM cards.
• Prefer a private APN service from the operator.
• Prefer M2M subscription SIM cards from the operator.
• Use private IP addressing from the operator for cellular network based
communications.
• If connected to a public IP network, do not use plain text protocols such as http,
SNMP and telnet. Always use VPN to connect to the device.
5.3
Configuring firewall and services
Enable the firewall and disable the unused services and interfaces in the device. To
start, disallow traffic and allow only the needed traffic. Use the default policy to
drop connections.
• Check that the firewall is enabled.
• For incoming connections, always filter (drop) all unused ports which may include
DNS, L2TP-VPN, SNMP and so on.
