This book provides a template with step-by-step instructions on how to respond and recover when hackers get into your SCADA system and cause building equipment to act erratically or fail completely. When hackers shut off the water, turn off the building power, disable the sewage effluent pumps and activate the fire alarm, you have to do something quick. It is even more alarming that hackers can do all those things at the same time-even from the other side of the planet. Not every equipment failure or power outage is a cyber-physical attack. When your building is attacked, you probably won't suspect it was a hacker-until you see a pattern. The building control system (BCS) will act "squirrelly" and you will know-it really is a cyber-physical attack. Once a cyber-physical attack occurs, it can mean years of court cases, job losses, higher insurance rates, and maybe even criminal litigation. It also takes years to overcome the loss of safety credibility to your employees and the local community. Cyber-Physical Attack Recovery Procedures provides a detailed guide to taking the right steps ahead of time, and equipping your facility and employees with the training, knowledge, and tools they need and may save lives. The book contains: A one-of-a-kind action plan describing how hackers attack building equipment, the extent of damage possible, and how to respond when a cyber-physical attack occurs. Detailed descriptions of cyber-physical attacks directed against SCADA systems or building controls, as well as cyber booby traps Invaluable appendices, including: Emergency Procedures, Team Staffing and Tasking, Alternate Site Procedures, a Documentation List, Software and Hardware Inventories, Vendor Contact Lists, External Support Agreements, and much more. What you'll learn Possible ways hackers can cause building equipment to fail. How to quickly assess the threat to his facilities in real time, how to stop a cyber-physical attack. How to restore equipment operation without doing any more damage. Who This Book Is For Architects, Engineers, Building Managers, Students, Researchers and Consultants interested in cybersecurity-attacks against facilities in the real world. Also for IT professionals getting involved in cybersecurity responsibilities.

This book investigates tradeoff between security and usability in designing leakage resilient password systems (LRP) and introduces two practical LRP systems named Cover Pad and ShadowKey. It demonstrates that existing LRP systems are subject to both brute force attacks and statistical attacks and that these attacks cannot be effectively mitigated without sacrificing the usability of LRP systems. Quantitative analysis proves that a secure LRP system in practical settings imposes a considerable amount of cognitive workload unless certain secure channels are involved. The book introduces a secure and practical LRP system, named Cover Pad, for password entry on touch-screen mobile devices. Cover Pad leverages a temporary secure channel between a user and a touch screen which can be easily realized by placing a hand shielding gesture on the touch screen. The temporary secure channel is used to deliver a hidden message to the user for transforming each password symbol before entering it on the touch screen. A user study shows the impact of these testing conditions on the users' performance in practice. Finally, this book introduces a new LRP system named ShadowKey. Shadow Key is designed to achieve better usability for leakage resilient password entry. It leverages either a permanent secure channel, which naturally exists between a user and the display unit of certain mobile devices, or a temporary secure channel, which can be easily realized between a user and a touch screen with a hand-shielding gesture. The secure channel protects the mappings between original password symbols and associated random symbols. Unlike previous LRP system users, Shadow Key users do not need to remember anything except their passwords. Leakage Resilient Password Systems is designed for professionals working in the security industry. Advanced-level students studying computer science and electrical engineering will find this brief full of useful material.

The Manager's Guide to Web Application Security is a concise, information-packed guide to application security risks every organization faces, written in plain language, with guidance on how to deal with those issues quickly and effectively. Often, security vulnerabilities are difficult to understand and quantify because they are the result of intricate programming deficiencies and highly technical issues. Author and noted industry expert Ron Lepofsky breaks down the technical barrier and identifies many real-world examples of security vulnerabilities commonly found by IT security auditors, translates them into business risks with identifiable consequences, and provides practical guidance about mitigating them. The Manager's Guide to Web Application Security describes how to fix and prevent these vulnerabilities in easy-to-understand discussions of vulnerability classes and their remediation. For easy reference, the information is also presented schematically in Excel spreadsheets available to readers for free download from the publisher's digital annex. The book is current, concise, and to the point-which is to help managers cut through the technical jargon and make the business decisions required to find, fix, and prevent serious vulnerabilities.
