In Hackers Beware, Eric Cole managed to explain how hackers get into computers, steal information, and deny service to legitimate users' machines. Cole, who worked with the monitoring of-attack SANS Institute as an instructor and security consultant, gave his readers specific knowledge of offensive and defensive weaponry as well as general familiarity with attack strategies and good security practices. It also allows the reader to understand specific texts further security, including what Northcutt Intrusion Signatures and Analysis Stephen. Cole's didactic style of most of the conversation, embracing the fact that most computer exploits can be conveyed as stories about what hackers want and the steps they take to achieve their goals. He interrupts the prose with line drawings that clarify what is passed between the machines involved in the attack, and pauses often to show the user programs' interface and the parts of their logs.
