Test your computer security with one click

Dagbladet's test engine can tell if you are registered with known security flaws.

(Dagbladet): How secure are your photos and documents? Not to mention databases containing sensitive company data or high-tech devices that are connected to the Internet?

In the last few months the newspaper Dagbladet has revealed poor computer security in Norway.

Dagbladet has revealed:
• 290 vulnerable control systems, in banks, schools, nursing homes - and a military camp
• 2048 surveillance cameras in private homes, night clubs, shops and restaurants
• 2500 control systems connected to the Internet with minimal or no security
• 500 of these control industrial or critical infrastructure
• Thousands of data bases and servers that give away content without passwords

Findings are in Norway alone. Your country is likely no better.

Test yourself As a service to its readers, Dagbladet has made it easy to test whether you have information or critical systems accessible to the Internet.

YOU CAN DO THE TEST HERE

The test is set up to automatically check your IP address. In this way you can test your own system, but not your neighbour's.

Dagbladet uses the Shodan search engine to find security holes. Shodan searches devices that are connected to the Internet. Such devices might include servers, control systems, mobile phones or CCTVs.

- Our search function is connected to the Shodan server. We did this subject to an agreement with the founder of Shodan, John Matherly, says editorial developer Ola Strømman.

Guiding The test engine is to be considered a guide and is not a guarantee of complete and full data security. The test engine checks a database where IP addresses have already been checked. This means that the result you get will not change even if you make system changes.

- Even if you are registered with open ports, this is not necessarily an error or a security hole. This may also include equipment that should be accessible, Strømman says.

The team has also created a visual guide to known security issues for you to play around with. You can also visit the project homepage.

How it works: There are 65,535 «ports» on the Internet. These are used to identify different computers or programs connected to an IP address and means that one computer could have several programs that are communicating over the Internet at the same time.

Shodan - and Dagbladet - looked at the 33 most common ports.

The test engine indicates open ports and what this could mean.
