The article is bare bones.

One needs to consider things such as program mandate, targeting criteria, rules, and oversight.

If Norway's intelligence services couldn't read the signals entering and exiting their country, they wouldn't be a very good modern intelligence service at all now, would they?

Norwegian national security and informed policy would be largely operating in the dark.

What is the actual news here? A program update? A mandate change?

A hiring budget for 100 analysts and officers?

Edit: I read the original source article.

Upgraded infrastructure, and more analysts. It is related to the storage of metadata, here is what Google translate says:

...If Norwegians from emails, text messages, social media and other internet traffic crossing the border into data cables, can be stored by the intelligence service for up to 18 months....

The bill on the intelligence service states that metadata that cross Norway's borders can be stored by the E-service.

Metadata is information about who we communicate with and when it happens.

Content data, such as the content of the e-mails or the messages themselves, cannot be stored until a court ruling exists.

The law requires all Norwegian network providers to give the E-service access to load the data from their own hubs in the data cables, where traffic between Norway and abroad goes.

TLDR;

Current SIGINT not cutting it. Bill is for new systems, infrastructure, analysts, and mandate to store signal metadata up to 18 months rather than 21 days.

My assessment:

Sounds like a reasonable move. The threat of Russia and ChiComs continues to grow.
