I find it interesting that the new Signal Regiment will be aligned with the civilian NCSC. This makes perfect sense as threats are no respecters of uniform or rank…:
[…] Modernising the UK defence sector is one of, if not the top priority for the MOD, acknowledging the fact that digital and cyber-based threats continue to develop their capabilities. As part of this objective, several programs have been launched aiming to bolster communication technologies, while ensuring they are kept secure. Investment pledges have been made over previous years, acting as part of the National Cyber Security Strategy, having been granted £1.9bn. The National Cyber Security Centre (NCSC) yielded from this strategy, and now operates as a core function of UK national security cyber defence.
In the announcement of the new 13th Signal Regiment, there were no details on how the new team would collaborate with the NCSC. It would be expected that the new team would operate under the banner of the NCSC, especially as it only has 250 members. However, it could be that the specialist team focuses specifically on critical networks operated by deployed military troops. Whereas the NCSC effectively deals with wide-ranging cyber-attacks that are faced in the millions per week.
