Networking Security 101: Responding to Attacks
If nations, particularly their media, followed these rules, there would likely be no terrorism at all.
Rule #1: Never let them see you sweat. Doing this only lets the attacker know of his/her/their success. It only serves to further encourage the attacker and others. Instead of providing any details, just post a note somewhere that mentions "temporary service outages."
Rule #2: Never publicly acknowledge the attacker. Doing so only feeds the notoriety which the attacker craves. This thread isn't helping.
Rule #3: Cooperate with the authorities to the maximum extent possible. They can't take the bad guys off the streets without the computer forensics evidence required for lawful prosecution.
Rule #4: Understand that as customers, some network outages are caused by physical breakdowns, others by logic (programming) breakdowns, and still others by cyber terrorists.
Again, drawing attention to their activities in any way, shape, manner, or form only encourages them further.
