Increase the reliability of your domain name

You can add to the reliability of your fi-domain name by following information security guidelines and enabling DNS security extensions (DNSSEC).

Pay attention to information security when you create web pages and use the internet. By anticipating risks, threats are less likely to occur. Moreover, legislation requires the protection of confidential information.

A computer and its data remain secure when you regularly update your

  • operating system
  • firewall
  • anti-virus software.

Remember also to install security updates on other programs.

The National Cyber Security Centre Finland (NCSC-FI) at FICORA provides assistance in issues related to information security violations and their prevention. On its website, the NCSC-FI informs the public about most recent information security threats and vulnerabilities.

DNSSEC protects name servers

DNSSEC (Domain Name System Security Extensions) is a service that improves the information security of name servers. In practice, DNSSEC is a kind of an insurance which guarantees that internet users access just the websites they intend to visit. Furthermore, DNSSC protects you from attacks targeted at the name server system.

DNSSEC ensures that responses to domain name system queries come from the right sender and that the response information has not been modified. When DNSSEC is enabled, responses to domain name system queries are digitally signed.

The domain name system gives each domain name an individual IP address (e.g. 87.239.124.120). The DNSSEC technology ensures that the computer sending the query (e.g. web browser) sees whether the response received at the web address through a domain name system comes from a server that has been registered as a trusted server.

To enable DNSSEC, contact the registrar maintaining the name servers for your fi-domain name.

Registry Lock provides added security

Registry Lock is an additional service for fi-domain names that are classified as especially critical (e.g. domain names of banks or governmental organisations). The service provides a greater level of reliability for your most valuable domain names. Registry Lock prevents unintended changes, deletions or transfers if the registrar's system is attacked.

Registry Lock increases the reliability of a domain name but it is an extreme measure as it prevents the administration of the domain name. Therefore, consider carefully whether Registry Lock is worth having as it also restricts your performance.

Contact your registrar to find out whether they offer Registry Lock.
