Well, the cyber-criminals are committing cyber-crimes in cyberspace and we need our cyber-intelligence to be up to speed.

(cyber-speed)

Government says cyber to differentiate from traditional "security", which means "establishing or maintaining control by putting people in cages or killing them". When talking with someone who can launch missiles, order soldiers to kill, or dispatch law enforcement officers to assault a crowd of students holding a protest, then saying cyber isn't ridiculous.

Computer security people just say "security" without any qualifiers, because none are required. When a salesman pitching an anti spam product says cyber, he's failing the shibboleth

Who cares? Honestly, who cares what word they use. We all know what they mean.

Comments like this one just seem to me like a form of avoidance: let's mock their vocabulary, because we don't want to think about the substance of what they're doing.

What do you think would be a better term?

Network security is accurate I think but not specific enough.

What's wrong with "cyber"? - does it not relate to computers?
