What is 802.1X port security? IEEE 802.1X is a standard for port-based network access control (NAC) that provides an authentication framework for devices trying to connect to a LAN or WLAN. The “X” in 802.1X represents the variety of authentication methods it supports. This standard is commonly used for enhancing network security by ensuring that…

What is TACACS authentication? TACACS (Terminal Access Controller Access Control System) is a protocol used to control access to network devices. It provides centralized authentication, authorization, and accounting (AAA) services for users who are trying to access network resources. TACACS operates by separating the authentication, authorization, and accounting functionalities into separate services: Authentication: This verifies…

What is WiFi certificate authentication? WiFi certificate authentication, also known as WPA-Enterprise or 802.1X authentication, is a security method used to authenticate users or devices on a wireless network. This method is more secure than the common pre-shared key (PSK) authentication used in WPA-Personal or WPA2-Personal configurations. Here’s a brief overview of how WiFi certificate…

What is a PKI certificate? A PKI (Public Key Infrastructure) certificate, also known as a digital certificate, is an electronic document used to certify the ownership of a public key. It’s a crucial component of the Public Key Infrastructure, which is a system for the creation, storage, and distribution of digital certificates. PKI certificates are…

How do you setup passwordless SSH? Setting up passwordless SSH involves a few key steps. Here’s a general guide: Generate a Key Pair on Your Local Machine: Open a terminal or command prompt. Run the command ssh-keygen to generate a new SSH key pair. You’ll be prompted to provide a file path to save the…

What is the LDAP protocol? The LDAP (Lightweight Directory Access Protocol) is a protocol used for accessing and managing directory services over an IP network. It is most commonly used for storing and retrieving information in a network directory. The protocol runs over TCP/IP or other connection-oriented transfer services. Here are some key points about…

What is a RADIUS authentication server? A RADIUS (Remote Authentication Dial-In User Service) authentication server is a server that employs RADIUS protocol to manage network authentication. Developed by Livingston Enterprises Inc. in 1991, the RADIUS protocol enables centralized authentication, authorization, and account management for users connecting to a network service. When a user attempts to…

What is SAML authentication? SAML (Security Assertion Markup Language) is an open standard for exchanging authentication and authorization data between parties, commonly between an identity provider and a service provider. Some key aspects of SAML authentication include: It enables single sign-on (SSO), so users can access multiple applications with one set of login credentials. The…

How do I fix a WiFi authentication error? A Wi-Fi authentication error can occur for various reasons, and troubleshooting steps may depend on the specific device and operating system you’re using. Here are some general steps you can try to fix Wi-Fi authentication errors: Check Password: Make sure you are entering the correct Wi-Fi password.…

What is EAPoL? EAPoL stands for Extensible Authentication Protocol over LAN (Local Area Network). It’s a network communication protocol used in wired and wireless networks to provide a framework for authenticating and controlling access of devices to a network infrastructure. EAPoL is specifically designed for use with the IEEE 802.1X authentication standard, which is commonly…

Unpacking the Role of Registration Authority In the intricate web of digital security and standards enforcement, the concept of a Registration Authority (RA) plays a pivotal role. Serving as the backbone for many standards organizations such as ANNA, the Object Management Group, and W3C, these entities are crucial in promoting the adoption and correct implementation…

What is SSH passwordless login? SSH passwordless login is a method that allows you to log into an SSH server without needing to enter your password each time. This is achieved using a pair of cryptographic keys: a private key and a public key. Here’s how it works: Generate Key Pair: On your local machine,…
