Security of network services

The security arrangements required for critical online services, such as security features, service levels, and management requirements, are carefully defined in advance. Online services include e.g. connections, networks and network security solutions (e.g. firewalls).

The security features of online services can be e.g. the following:

• required security-related technologies such as authentication, encryption technology, and network connection management tools
• the technical parameters required for a secure connection to network services
• online service usage criteria that restrict access to the online service or applications as needed

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.

For example, when the fault tolerance of a telecommunication network is critical, it can be further improved by procuring basic network services through several routes and through several service providers.
