Computer security system (8)

Ross

I believe the answer is:

firewall

(Other definitions for firewall that I've seen before include "A protective system" , "Software protection for computer" , "Computer security system against online attack" , "network protection" .)

I've seen this clue in The Irish Times and The Guardian.
