NAC with security rtr

Hello

We want to implement a NAC solution for people who call the House HO, then goes to internet through our internet router.

This router contains the security feature and NAC is activated (you can see it from the web interface)

However, a partner of cisco suggests to use the clean access server and not the router security.

is there an advantage of the use of the own access servers or limitation of security rtr.

Note: we only need check windows updates and antivirus updates when computers access the internet

Well, both the NAC framework (SNAC on your router) and NAC Appliance (Clean Access Server) will work. You can dial via PSTN/ISDN or VPN using Cisco VPN Client. In addition, you can buy NME-NAC-K9 module for your router and it will work as clean access server.

To use the framework of the NAC, you'll also need Cisco Secure Access Control Server (ACS CS) 4.0 + (4.1). It's a commercial RADIUS server and is not cheap.

In addition, to check the antivirus updates your antivirus product must be accompanied by the NAC framework or device. For a list of supported products, take a look at:

http://www.Cisco.com/go/NAC

NAC http://www.Cisco.com/Web/partners/pr46/NAC/partners.html (frame)

http://www.Cisco.com/en/us/docs/security/NAC/appliance/Release_notes/416/416rn.html (NAC Appliance)

Framework of the NAC that you will need to integrate provider .dll files in the Cisco Trust Agent (for all of your providers of antivirus!), and then distribute CTA all the PC user using a mechanism out of band (not easy). CTA is a must for the NAC framework.

NAC Appliance automates this. It is a stand-alone product (not .dll files). Clean access agent can check the anti-virus supported by himself. It can be installed on the PC via a mechanism out of band or downloaded from the login Web page. In addition, Java / ActiveX agent is supported and can check your PC for compliance as well.

Verification of Service Pack number is not

difficult in these two products. However, to check the patches for Windows, you need to create complex rules as part of the NAC. When a new patch is released by Microsoft, you will need to change your rules manually (not easy). NAC Appliance automates this. It can download rules on the Cisco site. But you will need to purchase technical support for it.

In general, set up and maintain the framework of the ANC are not an easy task. However, you can buy additional products, integrating them into the frame and they will automate a lot of things for you. It is cheap and easy. NAC Appliance is autonomous. You don't have to be anything else.

  • HP Deskjet 3055 A does not connect to the WIFI with security

    I'm trying to configure a Deskjet 3055 A on my DD - WRT router.  I am a highly qualified network engineer, so I don't know 100% what I'm doing.

    First, DD - WRT supports WPS connection, because these are very precarious.  This means that my only way to connect the pritner to my home network is to connect to my PC and use the Setup utility (downloaded from your page drivers) I use the 28.8 version.

    My router supports the 2.4 and 5 GHz and I know the printer is only 2.4 GHz.  I disabled completely the 5 GHz network in order to connect the printer, even though it shouldn't have any effect.

    I restarted my router and reset the printers wireless network using its integrated control panel.

    In any case, after a shameful 2 hours troubleshooting, I did discover that the printer WILL NOT CONNECT to the WIFI network if any security is applied against it.  It works 100% fine with open security however, it is totally unacceptable.

    I tried both WPA Personal and WPA2 Personal, both with the same effect.

    For reasons to try, I added also the printer to my network WIFI open and tried to manually change the setting WIFI via webinterface of printers, however, whenever I try and access the wireless configuration wizard, I simply get an error message saying "Internal system error" - eventually I managed to work around this another bug that has been there for years (see http://h30434.www3.hp.com/t5/Printer-Networking-and-Wireless/Internal-System-Error-prevents-access-t...

    After installing printers web interface WIFI, the problem is always the same and it does not connect.

    HP, we were in the order of 2500 of these printers for users of our remote site.  If you don't come to the top with a quick solution/bug fixed, consider the lost business!

    Concerning

    Ian

    After playing well, I managed to find a solution for this!

    For all users who are unable to find a solution by using the other methods, here's what to do.

    Change your local network to open the safe but note your WIFI settings for your default installation.

    Connect the printer to the open network the HP software (via USB cable)

    Go to the URL of the printer, but make sure that you connect through HTTPS - if you get an internal system error, keep refreshing until it works (WHAT A JOKE!)

    Click on 'Network', then click 'Advanced' on the left.

    Enter the network settings as they need to be secured.

    Downstairs, check "in an infrastructure network, use 802. 11b / g behavior (assuming that your assisted supports g, otherwise use the b only option), then click on apply.

    Turn on your wireless security, on your router and then the printer should connect!

    I am really confused as to why this is not automatically enabled, if the printer is not working with security on a Wireless N network wireless, then have this as the default!

    HP - feel free to thank me in this post!

    MSN Outlook, hotmail "IE has blocked this site to display content with security certificate errors. Click here for options... »

    How can I get rid of this irritating pop-up message whenever outlook is open?

    Without knowing what are certificate errors, it is a shot-in-the-dark.

    80 90% of certificate in Windows XP errors can be attributed to one of the following two issues:

    1. Time Date, time, time zone, or light of day on your computer is/is not set correctly.  The time on your machine should be within 5 minutes of real time for certificates authenticate properly.  Right-click on your taskbar clock, and select time settings to check the correct time.  Synchronize time via Internet can solve this problem.
    2. Windows XP does a poor job of keeping its root certificates (certificates by which all other certificates are considered) up-to-date.  The newer versions of Windows did a much better job.  It certainly wouldn't hurt to update your root certificates and in many cases, this is all you need.  For update, visit the following article:
      "Members of the certificate program root Windows.
         <>http://support.Microsoft.com/kb/931125 >
      Then go down to the subsection titled "root Update Package (for Windows XP only).  Then click on the option "update for root certificates for Windows XP... "the link.  This will take you to the last downloadable update.  Download the package on your computer and double-click it to update your certificates

    One of the above should solve your problem.

  • problem with secure access

    Recently, I buy a scandisk 4 GB USB key.  It came with secure access software.  I failed and eventually remove the software.  Then I downloaded the software to access secure on my USB key.  I got the arch in place.  Then I closed it down.  Now, whenever I try to run access secure - it takes several minutes before I get the logon screen.  What's wrong?  What do I ned to do?  I am running windows 7 64 bit.

    OK, good analysis fb65.

    I have no experience with SecureAccess download but the blade I bought recently has SecureAccess on this and I have to suspect that they are similar if not identical.  Mine also shows a version of 1.1.19269.0.

    When I started the SecureAccess departure he asked if I wanted to sign up 2 GB of online storage, which I refused.  I suspect that you have accepted the offer, and that's why you try to connect to the ' net when you start SecureAccess.  I don't know how to disable this option, but I know not how to bypass links chiken.

    Go to your Windows\System32\drivers\etc.  You will find a file named hosts simply.  No extension.   Open the file with Notepad and down add this line:

    127.0.0.1 yuuwaa.com support.dmailer.com # SecureAccess

    Instead, you can try

    127.0.0.1 yuuwaa.com # SecureAccess

    One or the other should reduce to nil the impact that tries to connect online.

    Hi Rick,

    Thanks for posting this question in the Microsoft Community.

    You should not have more than one security software or antivirus installed on the computer, because they are a potential for conflict between them. Thus, it is advisable to have security software installed on the computer.

    You can read these articles and check if that helps.

  • UserPOV does not not en with security filters

    I am trying to create the following scenario

    Create a standard model EN assuming standard dimensions. One of which "Department", I added security.

    My grid is the standard period through the top and the accounts on the side.

    My end user has Instance1 and Idescendants of this division. Instance1 is under the TotalCompany node, and that the user does NOT have access to TotalCompany.

    I have also disappeared in the preferences under this user, and then select Instance1 as my preference of the user. Without that it matters, but it is a cube of planning versus direct to Essbase.

    Now as the Administrator reports, I put the point of view of the Department, and the default setting is TotalCompany. But when the user tries to open the report it shows you that the user doesn't have access to the Member of the Department. But it does not allow himself to someone else, it just stops.

    When I move in Department grid POV and select Instance1, it works fine (so security is not the real problem here). But it does not on the whole as an option I want a standard report but to work with security to users.

    Any suggestions? Or should I do this a different way.

    Can you please check if the preview UserPOV is checked.
    In the workspace, go to file-> Preferences-> financial information, there is a button to activate the preview UserPOV
