Communications and control networks

Cyber criminals can exploit configuration errors or technical vulnerabilities in applications, firewalls, or networks to access our information.

An organization must use defense-in-depth technologies to protect against, detect, and respond to cyber-attacks. The techniques should be suitable for controlling physical, logical and administrative controls.

Endpoint security management system can be used to demand the desired security criteria from the devices before they are allowed to connect to the network resources. Devices can be laptops, smartphones, tablets or industry-specific hardware.

Criteria for the use of network resources may include e.g. approved operating system, VPN and antivirus systems, and the timeliness of these updates.

The use of the wireless network is secured with sufficient keys and the connection traffic to the network router is encrypted. The wireless network for guest use is isolated from the company's own internal network.

An appropriate log is generated from the use of the network to enable the detection of actions relevant to cyber security.

The normal state of network traffic (traffic volumes, protocols, and connections) is known. In order to detect anomalies, there is a procedure for detecting events that are different from the normal state of network traffic (for example, anomalous connections or their attempts).
