Configure 802.1X on Mojo

Configure 802.1X on Mojo Networks Access Points Securing a remote organize implies venturing up past the preshared key verification of Mojo. The shortcoming in preshared key is the secret word that's shared among individuals and over numerous gadgets. In the event that a individual or gadget takes off the organization, the secret word must be changed to avoid that individual from joining the arrange. A more grounded way of securing the remote organize is to utilize 802.1X. In this case, we are going go over arranging the Mojo Systems C-120 access point as the authenticator which is able point to our FreeRADIUS server. Within the Mojo Remote Director, Tap on Configuration at the beat menu and after that click on Device Configuration within the primary board. - Next, click on SSID Profiles to modify the SSID in which we will configure 802.1X. - Select the SSID in the list where we will configure 802.1X security. You may have multiple SSIDs listed here. - While in the Edit Wi-Fi Profile subconfiguration menu, the first option we want to display is Security. Click on it to expand the options. Make sure the Security Mode is set to WPA2. Right below it, select 802.1X. To arrange our verification server, seek for the area Sweep Verification. A Essential and Auxiliary Verification server can be designed. In this illustration I will arrange as it were one. Input the subtle elements of the Verification server. When total, press on Spare at the foot of the page and confirm network to the SSID. Utilizing the Observing tab, confirm the gadget is effectively associated. In my arrangement I am utilizing EAP-TTLS which is designed to confirm gadgets employing a username and secret word.   Read the full article

Investigadores descubren nuevas formas de hackear contraseñas WiFi protegidas con WPA3

El mismo equipo de investigadores de ciberseguridad que descubrió varias vulnerabilidades graves, denominadas colectivamente Dragonblood, en el estándar de seguridad WiFi WPA3 publicado recientemente hace unos meses, ahora ha descubierto dos fallos más que podrían permitir a los atacantes hackear las contraseñas WiFi .

WPA, o WiFi Protected Access, es un estándar de seguridad WiFi que ha sido diseñado para autenticar dispositivos inalámbricos mediante el protocolo de Estándar de cifrado avanzado (AES) y está destinado a evitar que los ciberdelincuentes escuchen nuestros datos inalámbricos.

El protocolo de acceso protegido WiFi III (WPA3) se lanzó hace un año en un intento de abordar las deficiencias técnicas del protocolo WPA2 desde sus cimientos, el cual se considera inseguro y vulnerable a ataques KRACK más graves desde hace tiempo.

WPA3 se basa en un handshake más seguro, llamado SAE (Autenticación simultánea de iguales), que también se conoce como Dragonfly, y que tiene como objetivo proteger las redes WiFi contra ataques de diccionario fuera de línea.

Sin embargo, en menos de un año, los investigadores de seguridad Mathy Vanhoef y Eyal Ronen encontraron varias debilidades (Dragonblood) en la implementación temprana de WPA3, permitiendo que un atacante recupere las contraseñas de WiFi al abusar del tiempo o las fugas de canal lateral basadas en caché.

Poco después de esa divulgación, WiFi Alliance, la organización sin fines de lucro que supervisa la adopción del estándar WiFi, lanzó parches para abordar los problemas y creó recomendaciones de seguridad para mitigar los ataques iniciales de Dragonblood.

Pero resulta que esas recomendaciones de seguridad, que se crearon de forma privada sin colaborar con los investigadores, no son suficientes para proteger a los usuarios contra los ataques de Dragonblood. En cambio, abre dos nuevos ataques de canal lateral, que una vez más les permite a los atacantes robar las contraseñas WiFi incluso si se está utilizando la última versión del protocolo WiFi.

Nuevo ataque de canal lateral contra WPA3 cuando se utiliza cifrado de curvas elípticas Brainpool

La primera vulnerabilidad, identificada como CVE-2019-13377, es un ataque de canal lateral basado en el tiempo contra el handshake Dragonfly de WPA3 cuando se usa cifrado de curvas elípticas de Brainpool, que la Alianza WiFi recomendó a los proveedores usar como una de las recomendaciones de seguridad para agregar otra capa de seguridad .

"Sin embargo, descubrimos que el uso de las curvas de Brainpool introduce la segunda clase de fugas de canal lateral en el handshake Dragonfly de WPA3", dice la pareja de investigadores en un aviso actualizado . "En otras palabras, incluso si se siguen los consejos de WiFi Alliance, las implementaciones siguen en riesgo de ataques".

"La nueva fuga de canal lateral se encuentra en el algoritmo de codificación de contraseña de Dragonfly", dijeron los investigadores, "confirmamos la nueva fuga de Brainpool en la práctica contra la última versión de Hostapd, y pudimos forzar la contraseña con fuerza bruta utilizando la información filtrada ".

Ataque de canal lateral contra la implementación EAP-PWD de FreeRADIUS

La segunda vulnerabilidad, identificada como CVE-2019-13456, es un error de fuga de información que reside en la implementación de EAP-pwd (Protocolo de autenticación de contraseña extensible) en FreeRADIUS, uno de los servidores RADIUS de código abierto más utilizados por las empresas como base de datos central para autenticar usuarios remotos.

Mathy Vanhoef, uno de los dos investigadores que descubrió las fallos de Dragonblood, indicó que un atacante podría iniciar varios handshakes EAP-pwd para filtrar información, que luego se puede utilizar para recuperar la contraseña WiFi del usuario mediante la realización de ataques de diccionario y fuerza bruta.

"El protocolo EAP-pwd usa internamente el handshake Dragonfly, y este protocolo se usa en algunas redes empresariales donde los usuarios se autentican usando un nombre de usuario y contraseña", dijo Vanhoef.

"Más preocupante, encontramos que el firmware WiFi de los chips Cypress solo ejecuta 8 iteraciones como mínimo para evitar fugas en los canales laterales. Aunque esto hace que los ataques sean más difíciles, no los evita". comentó la pareja de investigadores."

Según los investigadores, la implementación del algoritmo Dragonfly y WPA3 sin fugas de canal lateral es sorprendentemente difícil, y las contramedidas compatibles con estos ataques son demasiado costosas para dispositivos livianos.

Los investigadores compartieron sus nuevos hallazgos con WiFi Alliance y tuitearon que "el estándar WiFi ahora se está actualizando con las defensas adecuadas, lo que podría conducir a WPA 3.1", pero desafortunadamente, las nuevas defensas no serían compatibles con la versión inicial de WPA3.

Mathy Vanhoef también mencionó que es lamentable que WiFi Alliance haya creado sus pautas de seguridad en privado. "Si hubieran hecho esto públicamente, estos nuevos problemas podrían haberse evitado. Incluso la certificación WPA3 original se hizo en parte en privado, lo que tampoco ha sido lo más ideal"

SA: Secure Methods of Communication :- Port based Authentication  IEEE  802.1X

In this secure method of communication, Involves 3-party communications:

Supplicant which is the User

Authenticator which is either the Ethernet switch or wireless access point

Authentication server which is the RADIUS (Remote access dial-in user service) database, Kerberos, LDAP

Supplicant is the user device which uses WAP protocol. To access a network service/resource. the device need to be get authenticated. This is connected to the through the authenticator or the access point, AP. This can:

software/app running 802.1X client

OS based supplicants like Microsoft Wireless Zero Conf–WZC or Apple’s airport client

The Chipset vendor’s supplicant software –Intel, Atheros, Broadcom

Authenticator (Access Point): This works as a relay between Supplicant and Authentication Server, There will be two Virtual Ports:

Uncontrolled : allows EAP authentication traffic

Controlled: Only authenticated traffic

Authentication Server: RADIUS provides centralized authentication, authorization and accounting management for user/host to access a network service/resource. This supports AAA (Authentication, Authorization and Accounting). Steps involved in communication:

Both Radius Server and Authenticator are configured with a shared secret

Authenticator sends a RADIUS Access Request message to the RADIUS server, requesting authorization to grant access via the RADIUS protocol. This request includes access credentials (e.g., username and password hash)

Authentication server checks the credentials using the RADIUS server, Kerberos server, LDAP or Active Directory server– returns one of three responses

Access Accept,

Access Reject,

Access Challenge for extra credentials

RADIUS server examples:

Elektron(US$750) is an entry-level and user friendly server

ClearBox(US$599) is designed for small networks, but it also scales to larger networks

FreeRADIUS(open source) is a solid and economical choice for Unix/Linuxadm
