This rather jumbled study of the state of modern American security issues falls short of indispensable but rises well above useless polemic. Saying the most in his own professional area, information-technology security, Ranum denigrates the prospect of "cyberwar," but then discusses in some detail the disruption that hackers have caused. Existing firewalls (of which the author is a professional developer) and virus protection are valuable, but only if universally and rigorously used. Hackers should not be rewarded for turning "expert" but charged with grand theft, and people with top-secret access need to be paid more than clerks. He praises the better-trained personnel of the Transportation Security Authority and goes on to denounce the opposition to profiling as the dreaded "PC's." If Ranum demonizes anybody in this breezy first-person polemic, it is the media, with the standard charges of giving information to the enemy ("Thanks a lot, guys!"), but he also makes a persuasive case for their abysmal technical ignorance. (The ACLU is not accused of anything worse than having a radically different perspective than his about the long-term consequences of the Patriot Act.) Ranum notes I that more cooperation with foreign intelligence agencies is needed, and is possibly occurring. The turf war between the FBI and the CIA has to end. And the government's information technology system needs to be rationalized, starting about 10 years ago. At the end of Ranum's stocktaking, one is left with an instant soup-like aftertaste, but there are enough cubes of information among the "You Should Know" sidebars and "Bringing the Point Home" boxes, particularly for technophiles, to make it worthwhile.
