Cisco Next-Generation IPS NGIPS appliances do this by correlating huge amounts of global threat intelligence to not only block malicious activity but also track the progression of suspect files and malware across the network to prevent the spread of outbreaks and reinfection.

They were so good!!! I really enjoy your lessons; they are the best I've ever seen. Keep up the good work and keep sending me the security threats updates as I read them with a fine tooth comb.
