English to Italian Law/Patents Law (general)

E' inclusa in un'ordinanza del Tribunale che nomina dei tutori per un disabile mentale. Il contesto è il seguente:
"- Security
The deputies are jointly required fortwith to obtain and maintain security in the sum of £££ in accordance with the standard requirements as to the giving of security. (...)
The deputy must ensure that the level of security ordered by the court is in place before discharging any of the functions conferred by this order."
Cosa si intende di preciso in questo caso con security? Pensavo a garanzia ma garanzia di cosa?
Grazie mille in anticipo!
