"In essence this books rounds up all the Cisco IPS related technologies, and hence serves as a good reference for Cisco IPS. This book is useful not only as an exam preparation guide for the Cisco IPS exam 642-532, but also as a reference book for those who work with Cisco IPS appliances on day-to-day basis."
