Cisco ASA url filtering

• 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.

• 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,.

  Hello

  is there any clear guide to install the device VM firesight with integration of module power of fire ASA? I found some documents that explained the ASA device unit firesight recording.

• The services configuration of firepower on Cisco asa 5506 with ASDM

  I have a few 5506 firewalls, and they are fully licensed with services of power, control, Protection, URL filtering, malware. I have intend running and configuration of all of this on the 5506 by ASDM. I was wondering if there are guides for a basic configuration and the implementation of policies available. Something to show a basic configuration which would technically begin inspection of traffic and work. Then I can edit and make changes to my taste.

  Thank you

  My recommendation to clients is to look at the Cisco Live, BRKSEC-2018presentation. Please refer to the 56 slide from for a good overview of how policies are installed in a module of firepower.

  There are also a number of other detailed guides available in the FireSIGHT Management Center product support page should you care to learn more about customization and operations. You can also find the series of videos of ASA FirePOWER on request to Labminutes.com useful to guide you on execution of operations of your system.

• 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.

• Integration of Websense with Cisco ASA

  Hello guys,.

  Little experience with a Cisco ASA so I want help from you.

  I have in my network of Websense solution worked with ASA firewall. It works perfectly fine, most discover that the ASA when working with Websense it sends only HTTPS IPthis causes some trouble in the report generated by Websense contained only the IP addresses instead of the names of the sites.

  Someone has already managed to integrate with Websense and did not go for it?

  Thank you all

  The reason why it only contains IP instead of the URL for the HTTPS traffic is that HTTPS is encrypted and the URL is in the encrypted session, so you see only IP instead of the URL.

  If Websense support HTTPS decryption, you'd be able to see the actual URL.

• 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.

• The ACE IPS Cisco and Cisco ASA AIP - SSM (IPS)

  Is there a difference between the features offered by the Cisco ACE IPS and Cisco ASA AIP - SSM (IPS) devices?

  Can we do without Cisco ASA AIP - SSM (IPS) of 'only' configuration/implementation Cisco ACE IPS.

  Cisco AVS/ACE emphasis on commissioning and to secure web-based applications. IP addresses do not focus on just the web applications and trying to get the multiple layers of the OSI stack. Consider the IPS as a general practitioner and the ACE/AVS as an eye surgeon, or something :)

  Here is the response from Cisco itself:

  http://www.Cisco.com/en/us/prod/collateral/modules/ps2706/ps6906/prod_qas0900aecd8045867c_ps6492_Products_Q_and_A_Item.html

  Q: how is Cisco AVS Firewall application differs from an intrusion prevention system (IPS)?

  A. IPSs are solid solutions of protection against targeted attacks of known vulnerabilities in major platforms such as Windows, Solaris, Apache or Microsoft Internet Information Services (IIS). Cisco AVS excels to protect against targeted attacks Web sites or enterprise applications. These applications can be built custom internal applications or software vendor. Signatures and security patches are generally not available for these types of applications, and building these security levels in each application, it would be almost impossible.

  Q: how is Cisco AVS Firewall application differs by a network firewall?

  A. The Cisco AVS 3120 and Firewall network such as the Firewall of Cisco PIX® and Cisco ASA 5500 Series Adaptive Security appliances are complementary products. The application Cisco AVS Firewall secures Web applications; excellent network in the network security firewall. and the Cisco AVS provides defense in depth for Web applications.

  Firewall network apply policy networks, IP addresses and ports; they have a wide range of application for many different protocols layer features. The firewall can and will be deployed in many locations, including the edge, edge of the enterprise network, branch, etc. Cisco AVS imposed the policy on data HTTP as URL, headers and parameters. Cisco AVS is deployed in the data center in front of Web applications

• Add the date of activation of the system of detention of intrusions and Cisco ASA FirePOWER

  Good evening

  I want to add detention system intrusions to Cisco ASA FirePOWER license (with I.P.S, protection MPAs., Apps and URL). Is possible that? I have to buy another license or only (not free) upgrade?

  the start date of the firepower Cisco ASA license-protection starts from the purchase date or from date of activation/installation on router ASA5506-X?

  Hi again, my responses below:

  (3) the L-ASA5506W-TAMÁS = is the correct part number if you are looking to get the model of 5506-X Wireless ASA. Don't know why ours (CDW) site has not listed :) However, we have listed promotional SKU: L-ASA5506WTAMC-1PR. For more information, I suggest that join you your CDW account manager. If you are not a customer CDW then I would suggest that you contact your local Cisco partner dealer

  (4) here's the datasheet FireSIGHT:

  http://www.Cisco.com/c/en/us/products/collateral/security/firesight-Management-Center/datasheet-C78-736775.html

  The device can be virtual or physical

  5.1) IOS-base-2960 - I'm not sure I understand the question. Can you elaborate a bit more on what you're asking here?

  5.2) I.D.S. requires no additional licenses. It is part of the solution if you buy above subscriptions. The main difference here is that IPS (Intrusion Prevention System) is deployed in line and he will drop the traffic/connections if a malicious activity is detected. IDS (Intrusion Detection System) is monitor only. Thus, if the malicious traffic is detected, firepower will alert you to this topic but he will drop all traffic.

  3DES/5,3) AES will be included at the time of the references you listed.

  I have two Cisco ASA 5510 firewall with a similar setup configuration and the AnyConnect SSL VPN works great.

  Hi Matt,

  You are probably landing on the tunnel-group by default - you will need to indicate which group to connect to the client. This can be done in different ways - I see that you already have a defined group aliases, but to be able to use that you must configure:

  WebVPN

  tunnel-group-list activate

  Alternatively, if you have only a single group, you can add 'group-url https://yourasa.yourcompany.com/ permit' to the webvpn attributes tunnel-group.

• Cisco ASA 55XX Transparent mode through a VLAN

  Hello team Cisco Forum!

  In a scenario where the Cisco ASA is in Transparent mode, it is possible to route the traffic of L2 other VLAN different that the VLAN native IP for the firewall management lies?

  Switches on the outside and the inside of the interfaces of the SAA are in trunk mode, and I'm moving ttraffic VLAN L2 from inside to outside and vice versa by using filters on switches (switchport trunk allowed vlan).

  Thank you in advanced for your support and comments!

  Yes it is possible, but you will be limited to 8 VLAN, or more precisely, 8 interfaces BVI so it's not a scalable solution.  The problem is that you will need to have different VLANS to the same subnet at both ends of the SAA.

  To clarify this point, lets say, you use the interface Gig0/1 and Gig0/2.  Gig0/1, you would set up subinterfaces with VLAN 2, 3 and 4.  Now, if you try to configure the same VLAN on Gig0/2, you will get an error saying something like this VLAN is already configured on another interface. I don't remember the exact error.

  So to get this working, you need to configure Gig0/2 with subinterfaces for VLAN... lets say... 5, 6 and 7.  you would then associate VLAN 2 and 5 with BVI 1, VLAN 3 and 6 with 2 Virgin Islands British and VLAN 4 and 7 with 3 British Virgin Islands.  Each interface BVI would have its own IP address for the subnet on which is to be filled in all of the ASA.
