• Firesight URL filtering - shows do not block page for https sites

  Hi all

  I configured to block certain pages of URL filtering. I configured the decrypting ssl as well. But I noticed that when a website https is blocked firesight does not display the block page. When the Web http site is blocked the block page shows correctly. Is this a limitation in the firesight?. The firesight version is 6.0.

  Thanks in advance

  SSL web filtering occurs with the common name of the server certificate. When the end user opens any SSL-based Web site. End system not the TCP connection with the server and then SSL handshake begins.

  The probe monitors the SSL handshake and when the server sends the server certificate. Sensor corresponds to the common name of the certificate with the access rule (rules based on a URL). If it matches the sensor blocks the connection during the SSL handshake. Therefore, the connection has been blocked before reaching the application protocol (HTTP GET request) so that the system doesn't send any response page.

  The sensor not the resignation certificate (SSL decryption) when it receives the certificate of the server, but at the same time / name common package (server certificate) corresponds to the access rule (URL blocking) to block the connection. Therefore, blocking connection has occurred then the SSL decryption is not the case. In this way, the system can save some resources (CPU / memory).

• Cannot select on FireSight URL filtering with license activated

  Hi community

  I have a FireSight 6.0 VM with 4 modules of firepower enabled from four 5506-X ASA devices.

  They are all updated to 6.0 the power of fire and FireSight, I have an activated license:

  

  Under management of devices for fire power I can't even select URL filtering:

  

  What should do?

  The permanent control (CTRL) license free of charge is a sine qua non for all licenses of the term-based subscription. The PAK, it should have been included with the ASA.

  If this is not your partner (or TAC) can call the sales order and you can then redeem it for a license.

• Cisco ASA url filtering

  I have cisco ASA 5515 and it works fine. Now, I want to activate the url filtering so that I can filter websites such as facebook, youtube, torrents and so on. I don't have the license for filtering url, and in accordance with the document of cisco, he said that we have no need for this from the url filtering license. So how can I block them?

• Basic URL filtering

  Hello

  I need to purchase a firewall with a base URL filtering. I only need to deny access to certain URL and do not use a service like Websense or something like that.

  I would do it with an international search report, as the family of 2800, because I don't need anti-x features but only base firewall, VPN and voice features.

  The other option is to use the ASA 5520, but I would like to make the URL simple filtering without the need to use the module of CSC.

  Is there a way to do this?

  Mario.

  There is no need to go to an ASA. Will do a Sri 2800.

• Failed to download from URL filtering

  Hello

  Download of URL database suddenly started to fail. Connections go through the proxy, but proxy shows that the connection is there and going through fine. And it worked fine a few moments ago.

  Check/var/log for possible clues, and in the var, there is a message:

  ISM - SF [4309]: [4415] CloudAgent:CloudAgent [WARN] DownloadURLDBFilesOnDC: read failure of power supply during the update of the database URL. Status:-4

  I couldn't find any relevant information on this error and the text, it seems that it may be the connection problem, probably should try to go without proxy. FMC has been restarted, which did not help.

  Are there more written logs that may contain something more? Could there be a related bug I've not stumbled on? I can only dream about if a person of 'inside' might be the meaning of this error/status code. :)

  CMF/FP 6.0.1.2.

  Hi Niko,

  We have failure to download, reported by several customers yesterday morning of URL filtering and the technical team is aware of this. At the moment everything seems to be resolved, and they work on the RCA. However, we submitted the bug, and the team works on the RCA.

• Power heat capacity of URL filtering

  Hi all

  Then I actually time based (quota) web access to users? For example, I want A group access the sites of Marketing 1 hour per day. Is something possible in firepower?

  Thank you

  You can only do with firepower modules (5,4) current and FireSIGHT Management Center.

  I heard the rumor in 6.0 (later this year), but we will have to wait and see if this feature makes the cut.

• URL filtering - allowing one single site, blocking all the others

  Hello.

  I want to use ASA to allow a computer to access a single website (www.tsf.pt).

  I used the following Setup, but I'm not be able to put it to work, since all web traffic is prohibited.

  access-list Inside_mpc line 1 extended permits object-group Web_Access virtual object TI any4 (Web_Access group allows http and https)

  Regex TSF "tsf\.pt."
       
  type of policy-card inspect http TSF
  parameters
  violation of Protocol action drop-connection
  not match request uri regex TSF
  Reset log

  TSF-filter-class of the class-map
  matches the access list Inside_mpc

  Policy-map filter TSF
  TSF-filter-class
  inspect the http TSF

  interface of TSF-filter service-policy inside

  My idea is that anything which did not correspond to the www.tsf.pt would be refused. After I failed to do so I configured the policy with an match request uri regex TSF (with delivery to zero and newspaper) and when I opened the site I have seen increasing political access number (it was just to check that the ASA dealt with regex).

  After I tried the following policy which does not also (did this because I didn't know if it was implicitly refuse at the end of the political map)

  type of policy-card inspect http TSF
  parameters
  violation of Protocol action drop-connection
  matches the query uri regex TSF
  Journal

   match not request uri regex TSF
  Reset log

  Is there something wrong with my config? Am I missing something?

  Thanks in advance,

  João.

  Hello, João,.

  Fix your regular expression:

  Regex TSF "\.tsf\.pt."

  You can test if your regex is correct by testing using cmd:

  ciscoasa (config) # test regex www.tsf.pt "\.tsf\.pt".
  NEWS: Regular expression match succeeded.

• Filtering on ASA URL tunnel through

  Hello

  IAM can't put this thread in which section firewall or vpn. I want to know if we can set up the filtering of URLS with websense through the VPN. If so, how can do us the same thing and if we can do it for the two site to site and remote access? Let's take an example with websense on the ASA1 DMZ. Now, if Site 2 wants to send to all of its users to 1 Site for the URL filtering, then back it out with its (ASA1) internet (with the external interface ASA1) is it possible?

  (192.168.3.0) Site1 - ASA1 - VPN - ASA2 - Site 2 (10.22.22.0)

  Jayesh salvation,

  (192.168.3.0) Site1 - ASA1 - VPN - ASA2 - Site 2 (10.22.22.0)

  Now I see 2 ways to apply:

  (1) URL filtering config on ASA1: with this configured and also the ASA2 configured to send all internet traffic also to ASA1, when the ASA1 sees the initial GET to a site request, it forwards the request to the time the URL-filling server and the web server. Now, when the web server responds to this request, the ASA1 will decide to drop or before it based on the response from the websense server.

  (2) URL filtering config on ASA2: once again with this configured and also the the ASA2 configured to send all internet traffic also to ASA1, when the ASA2 sees the initial GET request, it will send traffic to the server on the DMZ ASA1 more url filtering web server. Please note that this query to the websense Server package, will have a source IP address of the external interface and destination IP of the server filter URL ASA2. We must therefore ensure that the 2 following things:

  ++ the ACL on ASA2 crypto includes an entry of external interface IP of ASA2 at the DMZ IP of the websense server and vice versa on ASA1.

  ++ an exemption nat configured on the DMZ ASA1 (acl pointing to the DMZ IP of websense server to the external IP of the ASA2).

  In this case labour will be similar. When ASA2 sees the server'sw web to answer the first GET request, decide to drop ot or transmit it on the client based on the response of the websense.

  Please let me know if that clarifies things.

  See you soon,.

• Filtering in Cisco ASA using module sfr Web

  Hello

  I have Cisco ASA 5515-x version 9.2 (2) and I use ASDM version 7.2 (2). I module 5.3.1 LICO of ASA. I want to activate the ASA web filtering feature. Previously, I used the method of expression regex in the SAA to perform url filtering, but it was not effective. Since then, I have the license for the management of firesight I want to use it.

  But I am confused as some cisco docs say to set the firesight management in vmware while others offer to run the boot image in the SAA itself. What is the right way to do it?

  The show module command, I see that my module of sfr is in place so that means the sfr module is pre-installed, and I can't do a lot of configurations?

  It would be better for me to run ASA itself, but if it does not work like that then I will configure in VM. So please me clearify that concerns my options and my best chance.

  If it should be installed on a virtual machine or ASA itself, then please give me the link to download the boot images and other files on cisco.com. I have the user name and password, but did not find the correct software.

  Thank you in advance.

  Your ASA 5515-x performs the minimum version required to support the fire power module (sfr). The module also runs the initial version of the software of the firepower for ASA-based module firepower.

  With this combination of Software ASA and firepower on your device, you will need to use an external administrator of firepower to manage module (create strategies, apply licenses, monitor events etc.).

  From ASA 9.5 (1) and firepower 6.0, you have the opportunity to make the most of the same functions via ASDM. You must upgrade the ASA (both ASDM) and firepower to achieve module.

  In both cases, you should Protect licenses and URL filtering for the module of firepower.
