Book Description

Mobile Authentication: Problems and Solutions looks at human-to-machine authentication, with a keen focus on the mobile scenario. Human-to-machine authentication is a startlingly complex issue. In the old days of computer security-before 2000, the human component was all but disregarded. It was either assumed that people should and would be able to follow instructions, or that end users were hopeless and would always make mistakes. The truth, of course, is somewhere in between, which is exactly what makes this topic so enticing. We cannot make progress with human-to-machine authentication without understanding both humans and machines. Mobile security is not simply security ported to a handset. Handsets have different constraints than traditional computers, and are used in a different way. Text entry is more frustrating, and therefore, it is tempting to use shorter and less complex passwords. It is also harder to detect spoofing. We need to design with this in mind. We also need to determine how exactly to integrate biometric readers to reap the maximum benefits from them. This book addresses all of these issues, and more.

Book Description

Mobile IP is most often found in wired and wireless environments where users need to carry their mobile devices across multiple LAN subnets. Examples of use are in roaming between overlapping wireless systems, e.g., IP over DVB, WLAN, WiMAX and BWA. Mobile IP is not required within cellular systems such as 3G, to provide transparency when Internet users migrate between cellular towers, since these systems provide their own data link layer handover and roaming mechanisms. However, it is often used in 3G systems to allow seamless IP mobility between different packet data serving node (PDSN) domains. Mobile IP is an Internet Engineering Task Force (IETF) standard communications protocol that is designed to allow mobile device users to move from one network to another while maintaining their permanent IP address. Defined in Request for Comments (RFC) 2002, Mobile IP is an enhancement of the Internet Protocol (IP) that adds mechanisms for forwarding Internet traffic to mobile devices (known as mobile nodes) when they are connecting through other than their home network. Mobile IP communication protocol refers to the forwarding of Internet traffic with a fixed IP address even outside the home network. It allows users having wireless or mobile devices to use the Internet remotely. Mobile IP is mostly used in WAN networks, where users need to carry their mobile devices across different LANs with different IP addresses. Mobile IP is not a wireless protocol. However, it could be employed for the IP infrastructure of cellular networks. The principle objective of this book are to provide an introduction to basic concepts and methodologies for mobile communication and to develop a foundation, that can be used the basis for further study and research in the field of communication engineering.

Book Description

Authenticating users with passwords is a fundamental part of web and mobile security. It is also the part that's easy to get wrong. This book is for developers who want to learn how to implement password authentication correctly and securely. It answers many questions that everyone has when writing their own authentication system or learning a framework that implements it. Store passwords securely What is the best password hashing function for your app? How many bytes of salt should you use? What is the optimal password hash length? How to encode and store hashes? When to pepper and encrypt hashes and how to do it securely? How to avoid vulnerabilities in bcrypt, PBKDF2, and scrypt, and which Argon2 version to use? How to update password hashes to keep up with Moore's law? How to enforce password quality? Remember users How to implement secure sessions that are not vulnerable to timing attacks and database leaks? Why is it a bad idea to use JWT and signed cookies for sessions? How to allow users to view and revoke sessions from other devices? Verify usernames and email addresses How to verify email addresses and why is it important? How Skype failed to do it and got hacked. How to avoid vulnerabilities caused by Unicode? How to disallow profanities and reserved words in usernames? Add multi-factor authentication How to implement two-factor authentication with TOTP and WebAuthn/U2F security keys How to generate recovery codes? How long should they be? How to rate limit 2FA and why not doing it breaks everything? Also... How to create accessible registration and log in forms? How to use cryptography to improve security and when to avoid it? How to generate random strings that are free from modulo bias? The book applies to any programming language.

Book Description

There is an intrinsic conflict between creating secure systems and usable systems. But usability and security can be made synergistic by providing requirements and design tools with specific usable security principles earlier in the requirements and design phase. In certain situations, it is possible to increase usability and security by revisiting design decisions made in the past; in others, to align security and usability by changing the regulatory environment in which the computers operate. This book addresses creation of a usable security protocol for user authentication as a natural outcome of the requirements and design phase of the authentication method development life cycle.

Book Description

This book is especially important for top management and other stakeholders of small and medium companies (SME or SMB). Small and medium companies are the major contributors to overall employment, the GDP of most countries, and the global economy. Recent cyberattack statistics show that SMEs are always a target for cybercriminals, posing a direct threat to the global economy if they are not protected. To understand the current scenarios in the SME segment, Dr. Shekhar Pawar conducted research to get insights into the current cybersecurity posture of each participant SME as well as the problems faced by businesses in adopting cybersecurity controls. The input from many SMEs working in different domains and from different countries helped Dr. Pawar understand the gaps that are helping cyberattacks to be successful. The top three issues identified during research were a lack of required financial investment, a lack of skilled resources, and not getting visibility into how investment in cybersecurity implementation will contribute to business growth. To address these problems, Dr. Pawar invented a new cybersecurity framework known as Business Domain Specific Least Cybersecurity Controls Implementation (BDSLCCI). It provides a tailored list of cybersecurity controls depending on the business domain of the SME, reducing costs and resources while providing a return on investment for businesses. BDSLCCI is now an AI ML-driven web platform with a few useful tools to assist companies in easily adopting it.
