Network Security

This guide takes the attacker's viewpoint in order to help defenders anticipate what intruders will try. Readers learn to think like the people who break into computer systems, so they can spot the signs of an attack before it lands. The book walks through the routes an intruder might use to pose as someone else by borrowing an address on a network, and the ways information can be collected by probing which services a machine offers, identifying its software, and eavesdropping on traffic. It also looks at how password files can be targeted. Alongside each threat comes the practical protection that network managers and everyday internet users can apply to keep their data out of reach.
