Why is remote authentication important?
MFA is important for remote workers for not only preventing unauthorized access, but in improving your organization's overall security posture. This is thanks to one of the great features of MFA: when an attempt is made to get into someone's account from an unauthorized device, the user will get a notification.
What are the 4 general forms of authentication?
Four-factor authentication (4FA) is the use of four types of identity-confirming credentials, typically categorized as knowledge, possession, inherence and location factors.
How many types of authentication are there?
There are three basic types of authentication. The first is knowledge-based — something like a password or PIN code that only the identified user would know. The second is property-based, meaning the user possesses an access card, key, key fob or authorized device unique to them. The third is biologically based.
What are different authentication methods?
Common types of biometrics include the following: Fingerprint scanning verifies authentication based on a user's fingerprints. Facial recognition uses the person's facial characteristics for verification. Iris recognition scans the user's eye with infrared to compare patterns against a saved profile.

What are Authentication Systems?
Authentication systems are security measures put in place to secure data and systems by requiring additional input beyond username and password for users to access a system. By providing this additional input, authentication systems help ensure that users are who they say they are. Authentication systems can require one other form of user input or more. These systems are sometimes called multiple-factor authentication, or MFA.

What is 2FA authentication?
Today there are a series of tasks, such as the update of software, maintenance work or changes to configuration, which are carried out periodically and are necessary for the system to function correctly. On occasions it is possible for these tasks to be carried out remotely and by individuals external to the organisation (e.g. manufacturers or engineers). This access may be performed in a non-secure way or from an environment that may have been compromised and it is particularly in these cases where it is recommended to implement two-factor authentication (2FA).
What are tokens based on?
Token Based on Software or Hardware 1 Google Authenticator :is a mobile application based on two-factor authentication which uses the Time-based One-Time Password algorithm (TOTP) and the HMAC-based One-time Password algorithm (HOTP) to authenticate the users. There is a PAM module for installation on Linux systems and authentication against RADIUS systems. 2 Authy: Open Source multi-platform application: iPhone, Android, or desktop and offers three authentication combinations: Authy SoftToken, Authy OneCode and Authy OneTouch. 3 Yubiko: solution based on hardware called YubiKey. It is a small hardware device that activates two-factor authentication with the simple touch of a button. 4 DUO: allows users to protect their logins and transactions through smartphones and the application can be used offline. It is compatible with Linux and Windows systems. For example, in Windows it would be possible for RDP connections.
What is a remote authentication dial in user service?
The remote authentication dial in user service (RADIUS) protocol is a third-party authentication system. RADIUS is described in RFCs 2865 and 2866, and it uses the UDP ports 1812 (authentication) and 1813 (accounting). RADIUS formerly used the unofficially assigned ports of 1645 and 1646 for the same respective purposes, and some implementations continue to use those ports.
How does trust pass authentication requests?
How a specific trust passes authentication requests depends on how it is configured; trust relationships can be one way, providing access from the trusted domain to resources in the trusting domain, or two way, providing access from each domain to resources in the other domain . Trusts are also either nontransitive, in which case trust exists only between the two trust partner domains, or transitive, in which case trust automatically extends to any other domains that either of the partners trusts.
What is the purpose of the Radius system?
RADIUS is considered an “AAA” system, comprised of three components: authentication, authorization, and accounting. It authenticates a subject's credentials against an authentication database. It authorizes users by allowing specific users' access to specific data objects.
What is authentication in NAS?
Authentication The server seeking access sends a request to NAS. The NAS then creates and sends a RADIUS Access Request to the RADIUS Server. This request acts as an authorization to grant access. Typically, a user name and password or some other means of establishing identity is requested for this process, which must then be provided by the user seeking access. The request will also contain other means of verification that the NAS collected, such as physical location of the user and/or the phone number or network address of the user.
What is domain in Active Directory?
Microsoft Windows Active Directory uses the concept of domains as the primary means to control access. For authentication purposes, Microsoft bases their authentication of trust relationships on RFC 1510, the Kerberos Authentication Protocol, and it has been integrated into Microsoft Windows operating systems since Windows 2000. Each domain has a separate authentication process and space. Each domain may contain different users and different network assets and data objects. Because Microsoft Windows also uses the concept of groups to control access by users to data objects, each group may be granted access to various domains within the system. If a two-way trust between domains is created, then groups belonging to either domain may access data objects from each domain.
What is a PAP server?
The Password Authentication Protocol (PAP) is defined by RFC 1334 ( http://tools.ietf.org/html/rfc1334#section-2) and is referred to as being, “not a strong authentication method.” [17] A user enters a password and it is sent across the network in clear text. When received by the PAP server, it is authenticated and validated. Sniffing the network may disclose the plaintext passwords. Sniffing refers to monitoring network communications and capturing the raw TCP/IP traffic.
