A value-packed two-book set that combines the best of engineering dependable and secure software systems with the best in-depth look at physical lock security and insecurity In Security Engineering: A Guide to Building Dependable Distributed Systems, Cambridge University professor Ross Anderson updates his classic textbook and teaches readers how to design, implement, and test systems to withstand both error and attack.  Now the latest edition brings it up to date for 2020. As people now go online from phones more than laptops, most servers are in the cloud, online advertising drives the Internet and social networks have taken over much human interaction, many patterns of crime and abuse are the same, but the methods have evolved. Ross Anderson explores what security engineering means in 2020, including: How the basic elements of cryptography, protocols, and access control translate to the new world of phones, cloud services, social media and the Internet of ThingsWho the attackers are – from nation states and business competitors through criminal gangs to stalkers and playground bulliesSecurity psychology, from privacy through ease-of-use to deception The economics of security and dependability – why companies build vulnerable systems and governments look the other wayHow to manage security and safety engineering in a world of agile development – from reliability engineering to DevSecOps Security Engineering ends with a grand challenge: sustainable security. As we build ever more software and connectivity into safety-critical durable goods like cars and medical devices, how do we design systems we can maintain and defend for decades? Or will everything in the world need monthly software upgrades, and become unsafe once they stop? In Tobias on Locks and Insecurity Engineering, renowned investigative attorney and physical security expert Marc Weber Tobias delivers a comprehensive and insightful exploration of how locks are designed, built, and — ultimately — defeated by criminals, spies, hackers, and even lockpickers. In the book, you'll discover the myriad ways that security experts and bad actors have compromised physical locks using everything from the newest 3D printers to 99-cent ballpoint pens. The book explores the origins of different lock designs and the mistakes that design engineers make when they create new locks. It explains the countless ways that locks remain at risk for attack. The author explains the latest lock designs and technology, as well as how to assess whether a specific solution will work for you depending on your individual security requirements and use case. You'll also find ways to differentiate between fatally flawed locks and solid, secure options as well as examinations of lock security from the perspectives of forced entry, covert entry, and key-control. Together these two books are the perfect guides for security and information technology professionals, design engineers, risk managers, law enforcement personnel, intelligence agents, regulators, policymakers, investigators, lawyers, and more.
