Securing Windows Logons Using a Password and OTP Securing Windows logons using a password and OTP A guide to enabling two-factor authentication (TFA) for local and remote access to Windows workstations and servers in the domain Enter OTP Harick Submit OTP www.adselfserviceplus.com Table of contents Why passwords aren't enough 1 Reinforcing Windows security by enabling TFA 1 How TFA for Windows works 2 Prerequisites 3 Steps for enabling TFA 4 Highlights of ADSelfService Plus’ TFA 5 Future proofing: TFA for all enterprise applications 6 About ADSelfService Plus 6 Why passwords aren't enough Passwords are the keys to unlocking access to your Active Directory (AD) kingdom, and cybercriminals will likely never stop targeting these passwords. All a hacker needs is a password cracking tool—there are a number to choose from—to gain access to your network, steal data, and wreck havoc on your enterprise. According to the Data Breach Investigation Report (2018) from Verizon, 81 percent of breaches were caused by stolen passwords. The password policy settings available in AD have not changed since 2000. Considering how far technology has come, and how adept today's cybercriminals are at using it, a password alone will no longer ensure security. With the right tools, a hacker can break into your AD domain in a matter of minutes. Knowing the risks associated with passwords, IT compliance laws such as PCI DSS have explicitly prohibited the use of passwords as the only authentication mechanism. Reinforcing Windows security by enabling TFA TFA adds an extra layer of security by authenticating users twice before granting access to valuable corporate resources—once through a standard password, and again through a unique identifier like a fingerprint or a one-time password (OTP) sent by email or SMS. TFA is a better way to authenticate users than relying solely on passwords. It ensures sensitive data remains secure, even in cases where a password is compromised. With TFA, even if an attacker gets access to a user's password, they would still need access to the user's mobile phone, email, or physical presence. TFA is almost impossible for attackers to bypass. While Microsoft provides Windows Hello for Business, which enables TFA for Windows, it comes with a lot of drawbacks and is quite costly. Windows logon TFA using ADSelfService Plus ADSelfService Plus, an integrated AD self-service password management and single sign-on (SSO) solution, provides a simple, aordable way to enable TFA for Windows machines across both local and remote desktop logons. 1 www.adselfserviceplus.com How TFA for Windows works When TFA for Windows is enabled in ADSelfService Plus, users will have to authenticate through two successive stages to access their Windows machine. While the first authentication will be through the usual Windows domain credentials, admins can choose one of the following as the second factor of authentication: SMS or email-based OTP. DUO Security. RSA SecurID. RADIUS. Admins can configure the factor of authentication based on OUs and groups. Here’s how it works: 1. When users log in to their Windows machine, Windows will prompt them to enter their AD domain username and password to prove their identity. 2. If they correctly entered their password, then the ADSelfService Plus authentication wizard will open. 3. Next, users must authenticate themselves with an OTP or through a third-party identity provider. 4. Users will now be successfully logged in to their Windows machines. User Name First Factor of Authentication using Second Factor of Authentication in Access to Windows machine Windows Login credentiails ADSelService Plus 1. SMS or email verification codes 2. DUO Security 3. RSA SecurID 4. RADIUS Server If the user fails the second factor of authentication, they will be taken back to the Windows logon screen and will have to start the process from the beginning. 2 www.adselfserviceplus.com How to enable TFA for Windows in ADSelfService Plus ADSelfService Plus comes with a built-in logon agent for Windows, which is a custom Credential Provider. You must install this logon agent to enable TFA for Windows. The logon agent must be pushed to the Windows clients and servers from the ADSelfService Plus web console itself. ADSelfService Plus also comes with a scheduler that will automatically scan your network for new computers added to the domain and install the logon agent in them. Let’s learn how to enable TFA for Windows. Prerequisites Download and install ADSelfService Plus. Deploy the logon agent for Windows (Credential Provider): You must install the logon agent through the GINA/Mac installation console (Configuration > Administrative Tools > GINA/Mac (Ctrl + Alt + Del) > GINA/Mac Installation) available in ADSelfService Plus. Enable SSL and login TFA: 1. Log in to the ADSelfService Plus web-console with admin credentials; if you're logging in for the first time, the username and password are both admin. 2. Navigate to Configuration > Administrative Tools > GINA/Mac (Ctrl+Alt+Del) > Windows Logon TFA. 3. Click SSL(HTTPS). Check Enable SSL Port, and click Save. Restart ADSelfService Plus. For information on how to enable SSL using a self-signed or CA-signed certificate, refer to this guide. 3 www.adselfserviceplus.com 4. Back in the Windows Logon TFA screen, click Login TFA. In Logon TFA settings, check Enable Two-Factor Authentication, and configure any one of the authentication methods provided. 5. Click OK. Steps for enabling TFA Log in to the ADSelfService Plus web console with admin credentials. Navigate to Configuration > Administrative Tools > GINA/Mac (Ctrl + Alt + Del) > Windows Logon TFA. Check Enable Windows Logon TFA. 4 www.adselfserviceplus.com By default, the Bypass TFA if ADSelfService Plus is down box is checked when you enable Windows Logon TFA. Checking this box ensures that users will still be able to access their machines if ADSelfService Plus, for any reason, is inaccessible. Click Configure Access and make sure that the access URL has HTTPS as its selected Protocol. Click Save. That’s it! TFA has now been enabled for Windows machines in your organization using ADSelfService Plus. Highlights of ADSelfService Plus’ TFA Mitigates risks associated with poor passwords Users nowadays have multiple accounts—both for personal and business use. To avoid forgetting the numerous passwords they have to remember, they often use the same password across all accounts, or set weak passwords. You can mitigate the risks of poor password behavior by enabling TFA. Granularly enforce TFA You can enforce TFA for all users or only for select individuals—such as those that have elevated privileges and are at higher risk of security attacks—through OU and group-based policies. Comply with PCI DSS and the GDRP TFA is a requirement in the latest version of PCI DSS (3.2). The European Union Agency for Network and Information Security (ENISA) also recommends implementing TFA as a technical measure to comply with the GDPR. 5 www.adselfserviceplus.com Future proofing: TFA for all enterprise applications ADSelfService Plus allows you to provide a simple, secure, and seamless logon experience to users across all their enterprise applications—not just AD. By enabling SSO in ADSelfService Plus, you can allow users to access all their SAML-based enterprise applications, even those that were developed in-house, by authenticating once using the same factors that they use to log in to their Windows machines. SSO saves users from entering their credentials multiple times a day, cuts down the number of passwords they need to remember to one, and improves their overall experience of using multiple applications. To learn more about enabling TFA and SSO for all enterprise applications, read this guide. About ADSelfService Plus ADSelfService Plus is an integrated Active Directory self-service password management and single sign-on solution. It offers password self-service, password expiration reminders, a self-service directory updater, a multiplatform password synchronizer, and single sign-on for cloud applications.

  • Passwordless Authentication: How Giving up Your Password Might Make You More Secure
    thalesgroup.com Passwordless Authentication: How Giving Up Your Password Might Make You More Secure White Paper Why Passwords Are Bad Passwords are one of the oldest security tools in the world of software and the internet. But in today’s environment, passwords cannot provide enough protection for businesses for several reasons. Password Fatigue Leads to Bad Hygiene Policy-driven password strengths and rotation leads to password fatigue, thereby contributing to poor password management. Verizon’s Data Breach Investigation Report1 indicates that over 70 percent of employees reuse passwords for work and personal accounts. A malicious actor could therefore abuse an employee’s credentials to access other applications and sensitive customer information. % out “123456” 81 ~40 4 of 5 “password” of breaches involve Average person People reuse same still among most use of weak or has roughly 40 passwords across popular password stolen credentials online accounts dierent accounts choices in 2018 People also tend to pick easy-to-hack passwords because of the trouble they have with remembering passwords. An analysis of over five million leaked passwords showed that 10 percent of people used one of the 25 worst passwords2. Seven percent of enterprise users had extremely weak passwords. Passwords Hurt User Experience Research by Carnegie Mellon University indicates that a properly written password policy can provide an organization with increased security. However, there is less accord over what should be in this policy to make it effective. To illustrate this fact, users commonly react to a policy rule that requires them to include numbers by picking the same number or by using the number in the same location in their passwords3.

  • Modern Password Security for System Designers What to Consider When Building a Password-Based Authentication System
    Modern password security for system designers What to consider when building a password-based authentication system By Ian Maddox and Kyle Moschetto, Google Cloud Solutions Architects This whitepaper describes and models modern password guidance and recommendations for the designers and engineers who create secure online applications. A related whitepaper, Password security ​ for users, offers guidance for end users. This whitepaper covers the wide range of options to consider ​ when building a password-based authentication system. It also establishes a set of user-focused recommendations for password policies and storage, including the balance of password strength and usability. The technology world has been trying to improve on the password since the early days of computing. Shared-knowledge authentication is problematic because information can fall into the wrong hands or be forgotten. The problem is magnified by systems that don't support real-world secure use cases and by the frequent decision of users to take shortcuts. According to a 2019 Yubico/Ponemon study, 69 percent of respondents admit to sharing passwords with ​ ​ their colleagues to access accounts. More than half of respondents (51 percent) reuse an average of five passwords across their business and personal accounts. Furthermore, two-factor authentication is not widely used, even though it adds protection beyond a username and password. Of the respondents, 67 percent don’t use any form of two-factor authentication in their personal life, and 55 percent don’t use it at work. Password systems often allow, or even encourage, users to use insecure passwords. Systems that allow only single-factor credentials and that implement ineffective security policies add to the problem.

  • Autopass: an Automatic Password Generator
    AutoPass: An Automatic Password Generator Fatma Al Maqbali and Chris J Mitchell Information Security Group, Royal Holloway, University of London [email protected], [email protected] March 9, 2017 Abstract Text password has long been the dominant user authentication technique and is used by large numbers of Internet services. If they fol- low recommended practice, users are faced with the almost insuperable problem of generating and managing a large number of site-unique and strong (i.e. non-guessable) passwords. One way of addressing this prob- lem is through the use of a password generator, i.e. a client-side scheme which generates (and regenerates) site-specific strong passwords on demand, with the minimum of user input. This paper provides a detailed specification and analysis of AutoPass, a password genera- tor scheme previously outlined as part of a general analysis of such schemes. AutoPass has been designed to address issues identified in previously proposed password generators, and incorporates novel tech- niques to address these issues. Unlike almost all previously proposed schemes, AutoPass enables the generation of passwords that meet im- portant real-world requirements, including forced password changes, use of pre-specified passwords, and generation of passwords meeting site-specific requirements. 1 Introduction Despite its widely-discussed shortcomings, text password authentication is widely used to authenticate users to online services. Many attempts have been made to replace simple password authentication, e.g. using biometrics, arXiv:1703.01959v2 [cs.CR] 8 Mar 2017 tokens and multi-factor authentication [4]. However, single-factor password- based authentication remains very widely used.
