Basic Security measures and publishes all measurements around online security that are responsible to publish, more on that in the publication policy. We also use the considerations in our code of conduct to determine which measurements are added.
This article lists which measurements are made around which techniques. A complete list of these, with references, is under the heading “overview of all measurements.”
This measurement policy is always evolving and responds to new developments. There are a number of exceptions to this measurement policy; these are described in the exceptions to the measurement policy.
Please read our disclaimer before using the measurement data. If you have questions, contact info@internetcleanup.foundation.
This article states:
- Information on the timeliness of measurements
- How measurements are valued more rigorously over time (roadmap)
- An overview of all individual measurements
- Includes links there documentation and test tools
Timeliness of measurements
Measurements are performed daily to weekly, this depends on the complexity and intensity of the measurements. A single inventory measurement is taken once every six months because it is noisy, the repeat measurement of this does take place once a week.
Because of the frequency of measurement, data in the reports is usually never older than a week. If it is, there is something special going on. We are still working on functionality that measurements older than two months never appear in the reports, and shorten this duration to one month at most.
You can always see how old a measurement is in the detail report. This is shown at the bottom of each measurement. For example, in the example below you can see that the measurement has been the same since 22 days and that the last measurement took place 1 day ago.

In addition, each map shows the data quality of the map. In that overview you can see which measurements are made and how many of them are up to data / outdated. In this overview, measurements older than 7 days are considered obsolete. This can also be seen in the example below.
The data quality is under the dot on the top left of the map. This ball colors depending on the quality. If it is orange or red, something is wrong. Usually it is on a green dot. If everything is up to date, there is a rainbow.

Roadmap of tightening measurements
Over time, there will be stricter monitoring. For example, some findings are green or orange now, but will become red in the future.
A new reading is often introduced as orange or green so people can get used to this and act before it turns to red.
The roadmap of this is still fragmented and not established. When individual measurements are introduced, there is often some mention of this. This information is still being gathered.
Overview of all measurements
Here is an overview of all measurements, assessments, documentation and tooling to measure yourself. When all of these are applied correctly, the organization is put green on the map.
If an organization keeps track of its online services and does minimize them, it is not too difficult to get to orange or even green.
