IOS Content Filtering
Hello, I have just purchased content filtering for an SR520 and an 881.
I find guides on Cisco.com relating to confiuration of filtering, but nothing with regards to reporting. I'm looking to log every time a page is denied, and what user (or IP) requested the blocked page.
Yes there is acache you can configure under the parameter-map.
You can also view it using command shown below
IOSrouter# sh
policy-map type inspect zone-pair urlfilter cache detail

Hi, all:
I'm trying to configure TrendMicro IOS content filtering. I have this working on a separate box, running 15.1.
On this particular testbed, I have a 2900 running:
System image file is "flash0:c2900-universalk9-mz.SPA.152-3.T1.bin"

I have not been able to get to the good part of configuring the ZBF.
I've looked over several configuration examples and can't figure out what I'm doing wrong, since I'm not able to see the command 'parameter-map' under the 'policy-map urlfiltering'
XXXXXX(config)#policy-map type inspect urlfilter trend-policy
XXXXXX(config-pmap)#?
Policy-map configuration commands:
class policy criteria
description Policy-Map description
exit Exit from policy-map configuration mode
no Negate or set default values of a command
XXXXXX(config-pmap)#
I thought it might be an issue with version 15.2.3, but according to configuration guides, commands are the same.
Can anyone provide some assistance?
TIA.
c.Hi Carlos,
I am having the same problem. I have seen a few diffenent configuration examples and they all show adding the "parameter type urlfpolicy trend parm-map-name" command but it doesn't exist, at least in 15.2(3)T1 and I see it listed in the the IOS documentation for 15.2. Maybe they forgot it :-)
I guess I will open a TAC case as I do not want to downgrade...
I will keep you posted if I find the answer.

Time pattern to allow user breakthrough URLFilter over IOS content filtering
hi
i have a client did request me to create such thing for them over IOS content filtering + Trend Micro based subscrition (till this level i'm pretty not sure it is feasible or what)
scenario would be:
like group 1 of users are the martketing subnet, then setting the time from 0800 hour to 1700 hour are prohibited to access any of the block blackilist site (either from local and/or trend micro reputation / category blacklist URL)
is there any way round i can enable the router to recognize the time then let user to gain access after 1700 hour?
Can TCL do this? any other way round for this
thank you

IOS Content Filtering - Is No More ?
Cisco very quickly End of Lifed the IOS Content Filtering offering last year
http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6586/ps6643/eol_c51-698205.html
For something with a minimum of a yearly lic involved, the EOL timing is shocking - you could have ordered product with a 1 year lic and come back now to find the offering is now dead (as in our case) so much for ROI !
Cisco are pushing Scansafe as their current offering, which has probably led toa falling out with Trend who provided the underlying service for
IOS Content Filtering. Scansafe does not economically cover the low end application, for which IOS Content Filtering was ideal i.e SMB space with 8xx or low end ISR routers. The Cisco answer is basically "perhaps you want to go and investigate solutions form other suppliers"
So we are left with a router platform which is fine and content filtering which was fine but are now unable to re-licence the URL filtering service and will stop working in about 30 days and there is apparently nothing we can do about it
Does anyone know if Trend still operate the URL filtering subscription service and whether theire is a way of geting a subscription renewal direct ?
(i'm not holding my breath on that - I am guessing the IOS content filtering hooks for the service being certificate based + Cisco license process will make that hard for anyone but Cisco)
Or of any alternative simple and cost effective solution we can configure the router to use
(please tell me we're not back to SurfControl/Websense solutions again..)
thanks
SezApproached the Cisco AM - frankly there was little or no interest in fixing such a low value problem. The spin was the Trend relationship ending was beyond Cisco control and Cisco hands tied - i.e. its not our fault (but strangely the problem is the customers)
Yes we could get some TMP discount - against the original hardware purchase but the hardware for lowend installs is negligible, it is the services time/cost in getting solution (and any replacement) into deployment which is the costly part and TMP makes no allowance for that.
Also scansafe solution is much more expensive, compared to IOS URL Filtering, so even taking off the minor TMP discount the answer form Cisco is basically - yep spend more money with us and we'll fix the problem we created for you. And why is there so little normal info on Cisoc.com for scansafe - i.e. covering SKU/ordering models etc... It always just ays 'ask your Cisco AM for details' - that may have worked when Scansafe was a separate company but a Cisco AM is unlikely to even answer the phone to talk about a $3K order
If Cisco really wanted to protect customer investment, why couldn't it provide through Scansafe a replacement service for IOS URL Filtering service, at similar cost and pricing model to that provided by the Trend integration? i.e. same kit, same config but pointed at scansafe cloud rather than Trend cloud. Then there would be no issue and a clean migration path provided for Ciscos valued customers
Probably answering my own question but scansafe appears to return to a cost related to the user count, whereas IOS URL Filtering service was a simple one off cost per router. This was ideal for low end application (the ISR800 series size of deployment) and comparable scansafe is way more expensive.
I have found we are not alone in this, most customers are only finding out about this mess when existing IOS URL Filtering licence's expire and go for renewal only to find the 3 month EOL process has stealthily boatanchored their implementation.

IOS content filtering on trend micro subscription
hi
i just finish setup the IOS content filtering on C1841. basically it's combo of local filtering and Trend micro subscrition based. all the parameter-map, class-map, policy-map and zone firewall setting is up and ready to go.
Some question to ask
1. how do i examine trend micro content filtering on it REPUTATION and CATEGORIES is really working?
as usual, after setup these command :
paramater-map type trend-global MY-GLOBAL-PARAM
server trps.trendmicro.com
pamater-map type urlfpolicy trend MY-PARAM
allow-mode on
block-pass message "bla-bla-bla"
class-map type urlfilter trend match-any trend-block-categories
match url catergory Adult-Mature-Content
class-map type urlfilter trend match-any trend-block-reputation
match url reputation ADWARE
policy-map type inspect urlfilter MY-ACTION
parameter type urlfpolicy trend MY-PARAM
class type urlfilter trend trend-block-categories
reset
class type urlfilter trendtrend-block-reputation
reset
so for my zone firewall policy:
policy-map type inspect out->in
class type inspect trafic
inspect
service-policy urlfilter MY-ACTION
then i do apply zone-pair to the outside and inside interface,everything set to go.
so far what i can block is only using URL-blacklist to block the whole domain. anyway how can totally left to trend micro subscription license to do with it all?
noelHmm... no thoughts over the weekend. Anyone?

IOS Content Filtering Using TrendMicro: Can I customize the block-page redirect-url?
I have IOS content filtering using the Trend Micro subscription service working on a 2911 running 15.1.(3)T3 with the security license option and a 30 day demo Trend subscription.
Once I figured out that the content filtering for Trend appears to be completely broken in 15.2 (even using docs for 15.2) I went back to 15.1 and it works great.
Everything seems great so far except I would like to have a more 'fancy' or custom blocked page where a user can have a couple links to either go to the trend micro reporting page http://global.sitesafety.trendmicro.com/result.php or some other page, and maybe some branding so they know the page is coming from our network and is not some fake security thing or phishing attempt or whatever.
I know I can use the 'parameter-map type urlfpolicy trend ' section to do a tiny bit of customization of the text that appears on the default blocked page display and there is an option for it to go to a simple redirect instead ('block-page redirect-url') but I wonder if anyone has any ideas on how to do more with either the built in page or the redirect-url to keep the information of what page the user was trying to access and why it was blocked (category etc.) while adding more features.
Thanks!
Oh, one last thing, this doesn't support any kind of 'user override' or anything like that does it? So that a network can have a filter applied but an admin could override the filtering to allow temporary access to something?Hmm... no thoughts over the weekend. Anyone?

Expiring ios content filtering
hello
now that IOS Content Filtering using Trend Micro is EOL and replaced by ScanSafe, can someone tell if ScanSafe is a subscription based and what are the new SKUs for ScanSafe
thanksYeah, Scansafe won't work until you purchase the subscription, and get that activated within the cloud since it is Web Security on the cloud solution.
Try to contact [email protected], and let them know your country and ask them if they can refer you to a local Sales Rep for ScanSafe. -
How can I achieve IOS content filtering using a Cisco router
Good day Everybody.
I would like to set up content filtering using IOS on my Cisco router. I already know how to do URL filtering but I want to restrict access to sites based on categories.
Is this possible without having to introduce an external device?Natively in IOS this is not possible. However you can configure CWS (Cisco Web Security). The router will forward web requests to a cloud based web security service.

IOS content fitlering through trend micro has been discontinued on 2800's (now) and 2900's (December 2012).
1. Is there a replacement solution for cloud based URL filtering on 2800's?
2. Looking at ScanSafe ISR Web Security on 2900's which I believe will work similar to TRM. I can't seem to find any SKUs for this solution through. Anyone knows anything about this?Hmm... no thoughts over the weekend. Anyone?

IOS web content filtering cannot get trend micro filter
hi, i just wondering how really i can get my router's content filtering connect to trps.trendmicro.com server again. previously it was success to get connect to the server, after i doing some changes on my zone-pair firewall then it cannot connect to the trend micro server anymore.
sh ip trm subscription status showing that i successfully connected and registerd
all the installation guide is doing accordingly,then i turn on my debug crypto pli validation and debug ip trm detail, all showing success connection to trendmicro site.
parameter-map type trend-global <param> are pointing to the trps.trendmicro.com, my class-map and policy-map didn't have any changes since last success connection.
zone-pair setting also attach with the right policy-map that serve for service-policy urlfilter <name>
overall, after my zone-pair firewall is UP again, then my web content filtering is gone, while registeration is made..
anyone have any idea what really happen?
thanks
NoelHi Yongkhang,
I think in order to figure out what is happening, we need to troubleshoot and see the config, data and other show commands. I'm not sure if you would feel comfortable posting that here. Therefore, i think its best to open up a case with tac on it so that it can be troubleshot to see why you cant access the trend micro server.
can you let me know what you mean by when you turn on your ZBF, your web content filtering is gone. Are you saying, when you turn on zbf, the web content filtering is no longer blocking or allowing sites?
have you ran the following debugs?
debug ip urlfilter detail
debug ip urlfilter event
debug ip url filter function-trace
also, what does this show:
show policy-map type inspect zone-pair urlfilter
Are you sure you have the class maps in the proper order since its processed sequentially..
regards,

My company currently uses a product called Websense that provides web security and content filtering. The content filtering operates as a proxy server and Safari doesn't work with it. We would like to migrate toward the use of iPad's, but we need to find a solutions for web/content filtering. We want the ability to globally establish policies and control the web filtering at the enterprise level. They would like to avoid replacing the browser. Any suggestions are greatly appreciated. Thanks
dcorwin
You can setup a proxy for your WiFi network in Settings > WiFi > (your SSID) > HTTP Proxy. This approach has two limitations:
1. You can only setup the proxy when the device is on that specific WiFi network
2. The setting cannot be locked and can be changed by the user at any time
When Apple announced iOS 6 two weeks ago, one of the slides had a suggestion of a Global HTTP Proxy, but the limitation above may still apply.
Another approach is to use a Safe Browser like Mobicip. The browser is equivalent to Safari in terms of functionality, and allows you to globally establish policies and control the web filtering at the enterprise level. The limitation of this approach, actually a limitation of iOS, is that links from other apps will need to be copy/pasted into the safe browser.
Hope this helps.

Hello
Previously I used Exchange 2010 with Forefront Threat Protection installed and this used to do a good job of stopping all the spam.
However since updating to Exchange 2013 earlier this year and enabling the integrated spam filtering everyone noticed a sudden increase in the amount of spam which was getting through which has been bad for a long time.
We have been living with it but in the last 3 weeks everyone has started getting about 40 emails a day from Pfizer for Viagra. All these seem to defeat the content filtering as Viagra is spelt with an extra I and the email address is always different.
Also images in emails are blocked by default but somehow all the images on these spam messages appear for everyone.
I am not sure the spam filtering is working at all and I'm not sure how to tell as ForeFront gives you a nice graphical dashboard but I can find nothing similar to this in Exchange and PowerShell seems the only way to configure the limited functionality
of the content filter.
Is there any way to get rid of these messages as it doesn't look very good when they are constantly popping up for everyone?
Thanks
Robin
Robin WilsonHello ManU
Thanks for the reply.
I have checked the logs and see this quite often:
AcceptMessage,,SCL,not available: policy is disabled
But other times it says this:

Which seems to indicate it is rejecting some.

Exchange 2013 SP1 EDGE role content filtering ?
Hello,
Have Exchange 2013 SP1 with CU5 with antispam enabled on mailbox role server. And i wonder if i deploy 2013 Edge role, will i get more granular content filter control, like there is in Office 365? For example: i want to treat empty messages as not
spam.
I have read that control of Edge server is done ONLY by powershell. So if edge role is deployed, still there is no content filter control in ECP (like in office365) ??Hi,
The Content Filter agent assigns a spam confidence level (SCL) rating to each message. The SCL rating is a number between 0 and 9. A higher SCL rating indicates that a message is more likely to be spam.
Based on my knowledge, I'm afraid we can't filter the empty messages and treat them as not spam.
Here is an article about content filtering in Exchange 2013 for your reference.

Conditions based on "EnvelopSender" in Content Filters
When defining Content Filters, I need to define conditions based on the sender of an email. For example, if the sender is Jim or John, and Subject Line contains a tag [CONFIDENTIAL], the action should be to encrypt the mesasge.
I realize this could easily be done using LDAP groups. But my problem is that for a number of opertaional reasons I cannot connect our IronPort to our corp LDAP.
An alternative is to directly code the user names in the condition statement. This is ugly and problematic for admins and possibly causes other problems as the number of users grows. Could anyone suggest an alternative?
Is there any option of having the Condition statement open a file and read the "sender" names from the file maintained somewhere on the local or a remote disk? Any other option?
Thanks.I would suggest looking at creating a dictionary that would list the addresses of the individuals. You can use that dictionary from which to base your planned action. Using LDAP is by far the better option for keeping a list up to date, as the dictionary will need to be updated regularly as addresses change, added or removed.

Using Content filters (HTML Filter)
Hello.
I'm having problem displaying an html-page in the portal with an url-iview. The problem is that the portal is accessed using HTTPS, and the url-iview links to a html-page using http.
This will generate a popup in internet explorer about unsecure content.
I thought that a way to solve this could be to connect KM to the page and then let the url-iview show the html-page throw the KM Repository.
This works fine, however there is still one problem.
Inside the HTML page, there is <IMG src> tags that reffers to the http site.
How can I configure HTML filters to rewrite all image and stylesheet references via KM instead of to the http-site?
I've tried to understand the documentation on Content Filters (http://help.sap.com/saphelp_nw04/helpdata/en/55/921d7bb0c611d5993800508b6b8b11/content.htm), but I don't know what to write in "Base Tag" property, or ir this even works.
Does anyone know if there is an example about this? Or perhaps know how to configure this?
Regards, MikaelThis can be done, but it might not be a optimal solution. You would basically parse each HTML file and replace the links before streaming the content. You can create your own version of com.sap.km.cm.docs component which streams the content of a HTML file by replacing the links. And you would use your own component for creating the KM doc iviews that way you will have altered HTML links.
