NCSC scanning Internet devices hosted in the UK — what you need to know? | 2009

NCSC — The United Kingdom’s National Cyber Security Centre — is the government agency responsible for providing support and guidance regarding the country’s cybersecurity. And now a vital part of their mission includes scanning all Internet-exposed devices hosted in the UK for any weak points.

  1. What is all the fuss about? 5 facts that you should know:
  2. Uncertainties and unknowns
  3. What you should do

To acquire a wider and more current view of the risk environment and to better prepare for potential emergency, they aim to map out the UK’s exposure to cyberthreats. Additionally, it aims to assist company owners in assessing their current level of internet security.

Read on to learn what you should know about this, your alternatives, and how to be ready for the government scanning whether your systems (all of them or just some of them) are also hosted in the UK.

What the heck is the big deal? Five things you should be aware of:

1 Making the UK the safest country in which to live and conduct business online is the NCSC’s stated goal. They have thus chosen to provide a data-driven picture of “the vulnerability of the UK” in light of this. They are concentrating on the most prevalent kinds of vulnerabilities that might have a significant influence on the stability and security of the system.

2 The scanning procedure, which will be carried out automatically without first requesting consent from company owners, includes all Internet-accessible systems located in the UK.

3 How are the scans going to be done? They will first determine whether a system contains any particular protocols or services that are linked to vulnerabilities by interacting with it in a manner similar to that of a network client. Later, they will Analyze the reaction you got and look for any weaknesses.

4 The NCSC’s operations will be carried out with the use of common tools that are hosted in a specific cloud environment. Only two IP addresses— and—assigned to will be used for all connections. Additionally, the government scanning probes will be recognized as coming from the agency (where possible, probably not in every case), for example, in the headers of HTTP requests. This will make it simple for any business to recognize these operations and decide to ignore them because they will be recognized as being carried out by the UK government and not by a cybercriminal.

5 You may always opt-out by sending an email to with a list of the IP addresses you want to have removed from the scanning process. The agency will verify your request and delete the IP addresses as soon as feasible. Just keep in mind that you will need to be proactive about alerting them once you make this decision, since the UK government won’t provide firms with any documents to complete prior to them beginning their work.

Unknowns and uncertainties

1 We don’t know what specific tests will be run, what will be scanned, or how disruptive everything will be. It really shouldn’t cause any disruption, though. Only your IT/security department will probably be aware of any NCSC activity. Your firm should continue to operate normally because your procedures and operations won’t be interrupted.

2 Whether the NCSC will alert businesses to any discovered vulnerabilities is unknown. The official statement doesn’t address this, so it might go either way. Receiving this information would be helpful so that those firms could make some rapid repairs (and more sophisticated ones as well).

3 We don’t know if there will be repercussions for businesses with found security flaws. Once more, probably not. Any organization that has security issues deserves adequate penalty, so as long as you adhere to the rules and regulations set out by the government, you should be safe.

As far as we know, these scans shouldn’t cause any problems. On the contrary, because of the nature of the scans, the objective is to aid in boosting business security, as well as national security. Security scans are also carried out by CERT Polska (the Polish Computer Emergency Response Team), but on a much lesser scale.

It’s also important to note that the NCSC has previously tested its scans in a controlled setting in order to assure utmost security. Additionally, they appear to be extremely similar to the scans conducted by private cybersecurity firms.

How you should proceed

Don’t panic, first of all. After all, the goal of the entire project is to stop cyberattacks and make online spaces safer for everyone to use, both from a client and corporate perspective.

Second, be organized. The aforementioned IP addresses can be added to your IT department’s recognized and trusted list so that government scanning won’t notify your security specialists and cause any unneeded replies.
