Cisco supports strong remote network authentication protocols?

Hello world

To the best of my knowledge IOS and IOS - XE nothing better than PAP support for authenticating users to network devices remotely. Is there a solution more concentrated than PAP, perhaps CHAP or P/EAP-based? Given the fact that OpenSSL already installed in these devices, I'm surprised that EAP-TTLS has not been adopted as a secure alternative.

Any ideas?

Hey Hod,

As far as I'm concerned, I don't know of any technology readily available to protect RAY sessions between the authenticator and the RADIUS server. The need for this is may be minimized by the fact that common applications of RADIUS (i.e., PPP, 802. 1 X and wireless authentication) establish a secure channel "supplicant" - RADIUS and use EAP to carry any authentication the begging and RADIUS is supported, with the authenticator, being relegated to a minor role of reconditioning of EAP messages in pairs of RAY - V and vice versa. This whole chain carrying identification user information can be protected by TLS, the actual communication between a RADIUS server and her authenticators is not protected by itself.

Many sources often States in a flippant remark that a VPN tunnel, such as IPsec, could be used to protect RAY sessions. It is hardly feasible, however, because many features in the role of authenticator (for example, switches) have no support for IPsec, either. It seems that RADIUS has been recently extended with TLS support - the "RadSec" is described in RFC 6614 but I've not supported by devices yet seen - honestly, I learned about this was now alone as I looking for some details during the drafting of this response.

Protect the old RADIUS protocol is always a challenge, it would seem.

Best regards

  • PAP authentication protocol

    Dear,

    When I ssh rocking the authentication protocol and authentication details in the snapshot attached, I see as a PAP_ASCII protocol that was used.

    I know that the PAP's clear password authentication protocol, so how do I justify to anyone connecting to my switch is secure.

    So the only way to access the device managed correctly is to use SSH and TELNET. from the NAS to the AAA (RADIUS) server, your password is encrypted anyway.

    Generally speaking, you would just follow the same process in the Sub URL, but add all the multiple networks local and remote networks that you want to be protected IPSEC.

  • EZVPN Mode of Extension of remote network

    Hello world

    I'm having the extension to the network mode remote ezvpn connecting to the server using pre-shared key authentication ezvpn. The remote router in network extension mode is on a dynamic IP. Now, every time the IP address on the remote router changes the its ISAKMP remain in State QM_IDLE even with peers who were the previous IP addresses of the remote router. When I connect with a VPN client software ezvpn Server tunnel for this customer pulls as soon as customers disconnects.

    How can I do the same thing for the remote router in network extension mode?

    Having this problem with the extension of the remote network it could easily deplete my resources ezvpn (only 10 tunnels IPSec allowed) if the IP address changes quite often on the remote router.

    Thanks a lot for your help.

    Kind regards

    Remi

    It looks like a bug. Use "sh cry his det isa" to see if KeepAlive is indeed active and "deb cry isa" to see that they are sent (you need the "periodic" option to check). IPSec security associations are deleted when IP address changes? Check with "sh cry ipsec his."

    Most likely, is a configuration of Miss of the AAA command on the switch.

    Hello

    (1) in the direction of LAN, they can access HQ LAN & resource, but cannot access the internet. I did not configure NAT on the router PH

    Answer:

    You must configure the NAT and crossed to the ASA HQ so that the VPN branch router provides LAN and u-Turn, access to Internet of the SAA.  You must first seup NAT for the branch on the SAA router subnet, then you must type the command:

    permit same-security-traffic intra-interface

    Here's a great example for VPN client hairpining.

    But all of a sudden when I try to connect wirelessly to it.
    He asks me to authenticate network right after that I entered the wep wireless password.

    It never asked before with the previous firmware.
    And I have no idea what is the user/pass.

    Can someone tell me what it is?

    This looks like standard network authentication. Go into the control panel. Network connections. Open the properties of the wireless network connection. Should be an Authentication tab where you have enabled authentication for 802. 1 x.

  • Windows 7 network authentication problem

    Having Windows 7 installed and have problems connecting to wireless internet. I see our wireless network, but whenever I click on it, I get a box titled "Network authentication" where it says "Please enter the credentials of the user" with a name and a password. My computer does not have a password. I don't have the credentials saved in the computer (I checked via the control panel). I tried all possible combinations of things and I can just go. If I 'x' out of it, behind it states that "additional connection information are necessary. I entered in the control panel and already ticked the box in the network and sharing Center to "disable password protected sharing. Has nothing. Any help to get rid of this annoying credential dialog would be MUCH appreciated!

    XbowSteve and Yelliez,

    I had the same problem: I bought a new computer (laptop ASUS U43F), and when I tried to connect to my home wireless network, I got a window that says "Windows Security" and "network authentication: Please enter the user credentials" also including a block a username and password.  I have three other machines humming happily my wireless network on Windows 7 and some on Mac OSX Snow Leopard.

    Problem was, I bought this computer today and do not enter a password system.  In addition, I was the one who put my wireless network and I did not need only an encryption key, user authentication.  In addition, there is no credential stored again, and I had only my admin account set up.

    #1: don't listen to those who say that it is a router problem, it is not.  IT DOES NOT ASK THE ADMIN ROUTER USERNAME AND PASSWORD!

    #2: don't take you in the long list of issues poorly answered in the nets of the 'credentials of the user.

    #3: IT IS NOT A QUESTION OF SHARING PROTECTED BY WORD!  ACK!

    Instead, follow these steps:

    (1) go to Panel and then network and Internet, then network and sharing Center.

    (2) click on manage networks wireless in the upper left of the window.

    (3) If your computer is new, then simply click 'Add '. If not, then click on "add", go through the steps below and choose the new network as your active network.

    (4) select 'Manually create a network profile.'

    (5) the form in the next window, including your network SSID, encryption, encryption, etc..  Select Conect automatically.

    (6) save.  It should say "Network successfully added."

    Presto!  Who should do it - I'm not so different.
