The theme of User Friendly is the tension between the desire for convenience and the need for security in the digital age.
Stoll argues that as we increasingly rely on computers and the internet, we are becoming more vulnerable to attack. He points to a number of high-profile security breaches in recent years, such as the hack of the Pentagon's computer systems and the theft of credit card numbers from major retailers, as evidence of this vulnerability.
Stoll argues that we need to take steps to protect ourselves from these attacks, such as using strong passwords, being careful about what information we share online, and keeping our software up to date. He also calls for greater cooperation between government and industry to develop new security measures.
Stoll's book is a wake-up call about the dangers of the digital age, but it is also a hopeful message. He believes that we can protect ourselves from these dangers if we take the necessary precautions. User Friendly is a valuable resource for anyone who wants to understand the security risks of the digital age and how to protect themselves from them.
