In this context: me being a little tongue in cheek.
In cyberpunk fiction "ICE" means "Intrusion Countermeasures Electronics"[1] and "breaking ICE" basically means something like "hacking through firewalls / network security". The term was made famous (if not outright introduced by) William Gibson's "Sprawl Trilogy" works, particularly Neuromancer. Amusingly enough the term - while fictional - has actually bled over into real-life usage a little bit.
