    Move Beyond Passwords Index The quest to move beyond passwords 4 Evaluation of current authentication method 6 Getting started with passwordless authentication 8 Early results to going passwordless 9 Common approaches to going passwordless 11 Email magic links 11 Factor sequencing 12 Webauthn 14 Planning for a passwordless future 16 Move Beyond Passwords 2 Introduction Traditional authentication using a username and password has been the foundation of digital identity and security for over 50 years. But with the ever-growing number of user accounts, there are a number of new issues: the burden on end users to remember multiple passwords, support costs, and most importantly, the security risks posed by compromised credentials. These new challenges are now outweighing the usefulness of passwords. The case for eliminating passwords from the authentication experience is getting more compelling every day. Emerging passwordless security standards, elevated consumer and consumer-like experience expectations, and ballooning costs have moved eliminating passwords from a theoretical concept to a real possibility. In this whitepaper, we will explore the case for going passwordless for both customer and employee authentication, and map out steps that organizations can take on their journey to true passwordless authentication. Move Beyond Passwords 3 The quest to move beyond passwords Understanding the need for passwordless authentication starts with understanding the challenges presented by passwords. The core challenges with passwords can be broken down into the following areas: Poor Account Security Passwords have spawned a whole category of security/identity-driven attacks — compromised passwords due to credential breaches, phishing, password spraying attacks, or poor password hygiene can result in account takeover attacks (ATO).

    What readers are saying about The Rails View This is a must-read for Rails developers looking to juice up their skills for a world of web apps that increasingly includes mobile browsers and a lot more JavaScript. ➤ Yehuda Katz Driving force behind Rails 3.0 and Co-founder, Tilde In the past several years, I’ve been privileged to work with some of the world’s leading Rails developers. If asked to name the best view-layer Rails developer I’ve met, I’d have a hard time picking between two names: Bruce Williams and John Athayde. This book is a rare opportunity to look into the minds of two of the leading experts on an area that receives far too little attention. Read, apply, and reread. ➤ Chad Fowler VP Engineering, LivingSocial Finally! An authoritative and up-to-date guide to everything view-related in Rails 3. If you’re stabbing in the dark when putting together your Rails apps’ views, The Rails View provides a big confidence boost and shows how to get things done the right way. ➤ Peter Cooper Editor, Ruby Inside and Ruby Weekly The Rails view layer has always been a morass, but this book reins it in with details of how to build views as software, not just as markup. This book represents the wisdom gained from years’ worth of building maintainable interfaces by two of the best and brightest minds in our business. I have been writing Ruby code for over a decade and Rails code since its inception, and out of all the Ruby books I’ve read, I value this one the most.

  • Cybersecurity in a Digital Era.Pdf
    Digital McKinsey and Global Risk Practice Cybersecurity in a Digital Era June 2020 Introduction Even before the advent of a global pandemic, executive teams faced a challenging and dynamic environ- ment as they sought to protect their institutions from cyberattack, without degrading their ability to innovate and extract value from technology investments. CISOs and their partners in business and IT functions have had to think through how to protect increasingly valuable digital assets, how to assess threats related to an increasingly fraught geopolitical environment, how to meet increasingly stringent customer and regulatory expectations and how to navigate disruptions to existing cybersecurity models as companies adopt agile development and cloud computing. We believe there are five areas for CIOs, CISOs, CROs and other business leaders to address in particular: 1. Get a strategy in place that will activate the organization. Even more than in the past cybersecurity is a business issue – and cybersecurity effectiveness means action not only from the CISO organiza- tion, but also from application development, infrastructure, product development, customer care, finance, human resources, procurement and risk. A successful cybersecurity strategy supports the business, highlights the actions required from across the enterprise – and perhaps most importantly captures the imagination of the executive in how it can manage risk and also enable business innovation. 2. Create granular, analytic risk management capabilities. There will always be more vulnerabilities to address and more protections you can consider than you will have capacity to implement. Even companies with large and increasing cybersecurity budgets face constraints in how much change the organization can absorb.

Published: 18 August 2020 Abstract: During the last few years, the FIDO Alliance and the W3C have been working on a new standard called WebAuthn that aims to substitute the obsolete password as an authentication method by using physical security keys instead. Due to its recent design, the standard is still changing and so are the needs for protocol testing. This research has driven the development of a web application that supports the standard and gives extensive information to the user. This tool can be used by WebAuthn developers and researchers, helping them to debug concrete use cases with no need for an ad hoc implementation. Keywords: WebAuthn; authentication; testing 1. Introduction Authentication is one of the most critical parts of an application. It is a security service that aims to guarantee the authenticity of an identity. This can be done by using several security mechanisms but currently, without a doubt, the most common is the username and password method. Although this method is easy for a user to conceptually understand, it constitutes many security problems.

Think twice about using SMS for OTP 10 5. Check compliance requirements carefully 11 6. Plan for lost devices 12 7. Plan to deploy MFA to remote workers 14 8. Phase your deployment: Be prepared to review and revise 16 8 Steps for Effectively Deploying MFA 2 The value of MFA Multi-factor authentication (MFA) has never been more important. With the growing number of data breaches and cybersecurity threats—and the steep financial and reputational costs that come with them—organizations need to prioritize MFA deployment for their workforce and customers alike. Not doing so could spell disaster; an invitation for bad actors to compromise accounts and breach your systems. Adopting modern MFA means implementing a secure, simple, and context-aware solution that ensures that only the right people have access to the right resources. It adds a layer of security, giving your security team, your employees, and your customers peace of mind. Unfortunately, while the benefits are clear, implementing MFA can be a complex project. In our Multi-factor Authentication Deployment Guide, we’ve outlined eight steps that you can take to better enable your MFA deployment: Educate your users Consider your MFA policies Plan and provide for a variety of access needs Think twice about using SMS for OTP Check compliance requirements carefully Plan for lost devices Plan to deploy MFA to remote workers Phase your deployment: be prepared to review and revise In this eBook, we’ll take a deeper dive into each of these elements, giving you tactical advice and best practices for how to implement each step as you get ready to roll out Okta MFA.

Especially, the smartphone app has become one of the most important forms to perform the authentication. This thesis describes various authentication methods used previously and discusses about possible factors that generated the demand for the current strong authentication approach. We present the concepts and architectures of mobile application based authentication systems. Furthermore, we take closer look into the security of the mobile application based authentication approach. Mobile apps have various attack vectors that need to be taken under consideration when designing an authentication system. Fortunately, various generic software protection mechanisms have been developed during the last decades. We discuss how these mechanisms can be utilized in mobile app environment and in the authentication context. The main idea of this thesis is to gather relevant information about the authentication history and to be able to build a view of strong authentication evolution.

  • Zero-Knowledge User Authentication: an Old Idea Whose Time Has Come
    Zero-Knowledge User Authentication: An Old Idea Whose Time Has Come Laurent Chuat, Sarah Plocher, and Adrian Perrig ETH Zurich Abstract User authentication can rely on various factors (e.g., a pass- word, a cryptographic key, and/or biometric data) but should not re- veal any secret information held by the user. This seemingly paradoxical feat can be achieved through zero-knowledge proofs. Unfortunately, naive password-based approaches still prevail on the web. Multi-factor authen- tication schemes address some of the weaknesses of the traditional login process, but generally have deployability issues or degrade usability even further as they assume users do not possess adequate hardware. This as- sumption no longer holds: smartphones with biometric sensors, cameras, short-range communication capabilities, and unlimited data plans have become ubiquitous. In this paper, we show that, assuming the user has such a device, both security and usability can be drastically improved using an augmented password-authenticated key agreement (PAKE) pro- tocol and message authentication codes. 1 Introduction User authentication still typically involves transmitting a plaintext password to the web server, which is problematic for many reasons. First, an attacker could obtain the user’s password using malware, a keystroke logger, phishing, or a man-in-the-middle attack. Second, the user might be using the same password on different websites, allowing a malicious server operator to impersonate the user. Third, if the website’s database is breached, although passwords may be protected by a hash function, a brute-force attack could reveal low-entropy pass- words. Fourth, as password-reuse and low-entropy passwords are problematic, users are constantly advised to pick new, long, complicated passwords.
