OK then, i'll handle protecting communication that way.
Concerning that, i have a question. The book lists Encryption as a specialization for Electronic Warfare skill, which i took because i wanted Stake to be better good at that. Now i have a greater insight into how encryption works (like protecting files and, with the same method, communication), i'm not sure if the specialization is just there as a remainder of the 4th edition. As for 5th edition terminology, encryption just seems to be used as a method to strengthen firewall protocols (thus giving +1 firewall while using the encrypt program).
According to the above, i'd like to replace that specialization with another one, on a skill connected to hacking and not belonging to the electronics skill group (as i took that as a group at character creation, i couldn't have taken a specialization for those skills).
A different question about the rules. How do you think ID forging works? According to the book (p. 367), the first three ratings of fake SINs don't really require too much supporting data in independent databases, is it possible for a character to make one that will stand, say, one or two cursory checks? Something not permanent, but working temporarily?
