This poses a significant security risk, as an unauthorized user could capture the data packets using a protocol analyzer sniffer and obtain the password. The advantage of PAP is that it is compatible with many server types running different operating systems.
PAP should be used only when necessary for compatibility purposes. The client sends the user name along with the encrypted password, and the remote server decrypts the password. It is an Internet standard that uses MD5, a one-way encryption method, which performs a hash operation on the password and transmits the hash result—instead of the password itself—over the network.
The hash algorithm ensures that the operation cannot be reverse engineered to obtain the original password from the hash results. CHAP is, however, vulnerable to remote server impersonation. MS-CHAPv2 uses two-way authentication so that the identity of the server, as well as the client, is verified. This protects against server impersonation.
MS-CHAP also increases security by using separate cryptographic keys for transmitted and received data. A key characteristic of EAP is its extensibility, indicated by its name.
Plug-in modules can be added at both client and server sides to support new EAP types. A RADIUS server receives user credentials and connection information from dial-up clients and authenticates them to the network.
Certificate services Digital certificates consist of data that is used for authentication and securing of communications, especially on unsecured networks for example, the Internet. Certificates associate a public key to a user or other entity a computer or service that has the corresponding private key. The CA digitally signs the certificates it issues, using its private key.
The certificates are only valid for a specified time period; when a certificate expires, a new one must be issued. The issuing authority can also revoke certificates. Standards for the most commonly used certificates are based on the X. Information on certificate services Windows includes support for certificate services. There are a number of ways that authentication can be accomplished, depending on network operating system and connection type. In this Daily Drill Down, I have provided an overview of some of the most common authentication methods, under what circumstances each is used, and how they work.

Hide Comments. My Profile Log out. Users provide their digital certificates when they sign in to a server. The server verifies the credibility of the digital signature and the certificate authority. The server then uses cryptography to confirm that the user has a correct private key associated with the certificate. Biometrics authentication is a security process that relies on the unique biological characteristics of an individual. Here are key advantages of using biometric authentication technologies:.
Biometric authentication technologies are used by consumers, governments and private corporations including airports, military bases, and national borders. The technology is increasingly adopted due to the ability to achieve a high level of security without creating friction for the user.
Common biometric authentication methods include:. Token-based authentication technologies enable users to enter their credentials once and receive a unique encrypted string of random characters in exchange.
You can then use the token to access protected systems instead of entering your credentials all over again. The digital token proves that you already have access permission. Authentication technology is always changing. Businesses have to move beyond passwords and think of authentication as a means of enhancing user experience. Authentication methods like biometrics eliminate the need to remember long and complex passwords.
As a result of enhanced authentication methods and technologies, attackers will not be able to exploit passwords, and a data breach will be prevented.

Password-based authentication Passwords are the most common methods of authentication. Multi-factor authentication Multi-Factor Authentication MFA is an authentication method that requires two or more independent ways to identify a user. Certificate-based authentication Certificate-based authentication technologies identify users, machines or devices by using digital certificates.
Biometric authentication Biometrics authentication is a security process that relies on the unique biological characteristics of an individual. Here are key advantages of using biometric authentication technologies: Biological characteristics can be easily compared to authorized features saved in a database. Biometric authentication can control physical access when installed on gates and doors.
The ability to refer to other systems —such as remote servers, data stored in the cloud, web- and mobile-based applications, etc. At the same time, it may also bring greater data protection and cybersecurity risks. The authentication level of assurance provided by online mechanisms varies according to the specific credentials, authenticators, and protocols used. In addition to choosing authentication methods with levels of assurance appropriate to the transaction, practitioners must consider their accessibility and convenience , particularly for vulnerable persons e.
For example, card-based authentication for remote transactions e. Input devices i. Device that can receive the password e. On-device match fingerprint, iris, face, PIN unlocks a private key used to authenticate against a server. The trusting organization must be comfortable that the other identity provider has acceptable policies, and that those policies are being followed. Federation protocols and assurance and trust frameworks facilitate federation of digital identity between organizations.
For federation to be effectively used globally, agreement and mapping with the ISO defined assurance framework and the adoption of standards are critical Source: Catalog of Technical Standards.
A trusting organization can capture and send the credential to the issuing organization i. For example, service providers in the UK can accept the credentials of multiple identity providers via the GOV. UK verify system see Box A trusting organization can accept credentials issued by another organization, but still authenticate and authorize the individual locally.
A trusting organization can accept specific attributes describing an individual from another organization. For example, a bank can request credit score from a credit bureau, rather than maintaining its own registry of credit information. A trusting organization can accept an authorization decision from another organization i.
Establish a trust framework—i. Determine federation protocols to be used e. For example, the combination of Open ID Connect and OAuth protocols allows for sharing different set of attributes, based on user consent.
Establish a secure communication channel between the relying parting service provider and the identity provider to enable an authentication workflow between the service provider and identity provider application. This is typically done using digital certificates to secure communication and may also involve passwords a shared secret to authenticate the application.
Unlike many other countries, the UK has no single foundational ID system except for a civil registry. People hold a variety of credentials—such as driving licenses, passports, birth certificates, and more—and rely on some combinations of these to assert their identities for various purposes. UK Verify system to provide a digital identity layer that would allow UK citizens and residents to authenticate themselves online for a variety of public and private sector services.
Rather than relying on a single, centrally provided digital identity credential, the Government developed a federated system with multiple digital identity providers who are certified by the GOV. UK Verify platform to provide authentication services.
UK Verify partnered with a number of private sector identity providers e.
