The elevation of the terrorism alert over the weekend to Code Orange or "high risk" is another reminder that the US still faces threats to grave threats here at home from those who seek to do us harm. It is also a reminder of the importance of the ongoing work to make our nation's critical infrastructure more secure. Along those lines, the paper I issued last week, "Do Feds Risk A Communications Blackout," warrants some attention.

The paper explains why it is important for federal buildings to be served by diverse communications facilities that are truly redundant. And it suggests that the federal government needs a targeted policy to focus in a systematic way on achieving a greater degree of network redundancy.

In my view, the government is doing a very good job of trying to prevent another 9/11. And we all pray, of course, it succeeds. But we're in this war for the long haul. Let's keep preparing to upgrade our infrastructure readiness as if the terrorists might succeed again in a major attack.
