Ms Abbott would be responsible for cybersecurity, as well as crime and policing
The important thing for being in charge of anything is to understand your own limitations. The philosophy I adopt for anything that I find I have been made responsible for is...
Is this thing something which lies in my defined skill-set?
If yes, then I should be able to cope
If no, then assess how important it is, risks, impacts, etc. If it is in any way serious, then I find someone for who this thing is their bread & butter, and utilise their expertise.
