    some info on the EU view which sec standards are potentially usable for cyber sec. at least for 5G no bigh surprises ISO 27, GSMA, 3GPP. Only ETSI cyber was a bit of surprise to me, considering the size of the group.

    Security. The new EU toolbox is nice. I only wonder if the local govs have the sufficient expertise e.g. to split the word "monitoring" into the different layers & domains e.g. DNS, malware (GTP_U), GTP_C, diameter, SS7, DoS monitoring, REST API, IP FW.....Its complex.

    Ian Levy has a good blog post on "issues" e.g. relating to market and business around 5G Security. Some stuff I do not agree on. I just wish he would highlight more the need (also business wise) of monitoring&penetration testing.

    security can now be measured in Euro...The idea on the table in Germany, if 5G security is not in place, up to 4% of company turnover.

    Hacking Team still seems to be up and running. Brief re-cap, that company got caught delivering to UN embargo countries surveillance services (incl using SS7)

    Configuration, in particular in combination with legacy nodes is one of the main challenges, that is why monitoring is so crucial....

    There are two big problems kicking the responsibility to the individual EU member states. There are very, very few 5G Sec experts in the world and every country cooking up its own schemata will not fly as it makes 5G Sec too expensive.

    that famous toolbox, I wonder what it will cover beside the ISO 27 stuff. Will it mandate monitoring, pentesting, TPMs, new features for NWDAF for IDS?

    is a good technology and can help in many good use cases, but it is scary what kind of use cases some come up with....spying granny app I wish 1984 would be fiction again......

    nice summary of security related issues and he hits some good points e.g. if something is mandatory to implement in standard, does not mean its mandatory to use by operator. Some stuff is missing like industry interfaces.

    Why go to a shop to do social engineering, if there is the RDP? Internet "risks" enter telco domain....
