IDS 4.0 custom signature - catch a URL
Hello
can someone help me with what I thought it was a simple task, but it happened to be a bit more than that. I want to see an alarm when someone tries to go the following URL: http://www.vasco.si/oddaljeno_delo.htm . Thank you.
This will require a two-step process. First, create a signature custom looking for the URI in question. For sensors 3.x, use the STATE. HTTP engine. 4.0 sensor, use the SERVICE. HTTP engine. You will fill the UriRegex with ' / oddaljeno_delo.htm'. This may be all you need. However, if you want to be exact, you need to create an alarm filter to match only on the IP address for the site in question. For more information about how to perform this step, see the documentation for the IDS.

I'm trying to create custom signatures to discover a foto \.zip [a - z] file in any incoming or outgoing email. Can I use the ATOMIC. TCP and look on port 25, or set up a SERVICE. Signature of SMTP and how you setthose to the top? Also, I'm looking at someone who was going to a URL with the words inside b.jpg? Is this a SERVICE. HTTP or what?
Thank you and your help would be very appreciated.

For your first question: S113 signature which will be published in the near future find the new Bagle.AI virus. To write a signature that detects the attachment, you can use the STRING. TCP. You look for something like:
CHAIN engine. TCP
Activated in real
Severity of information
AlarmThrottle in a nutshell
CapturePacket False
Direction ToService
MinHits 1
Protocol = TCP
RegexString [Ff] [Ii] [he's] [Ee] [Nn] [Aa] [Mm] [Ee] [=] [""] [Ff] [Oo] [Tt] [Oo] [a-zA-Z] [.] [Zz] [Ii] [Pp] [""]
ResetAfterIdle 15
ServicePorts 25
StorageKey = STREAM
Your second question:
You use the SERVICE. HTTP and your signature might look like:

Help with Custom Signature Bulding
Can someone help me with this. I want to build a customized for the particular http string signature trigger.
http://150.50.15.110/MyApp?Data=01234567890&user=Joe
The goal is whenever the data attribute value is a 11 digit or more, it must trigger. Otherwise it should not. You must also use RequestRegex only. It is a laboratory of labops, but I've never had it work even with their solution. Every time I try to match a? (i.e-?) It does not work in the custom signature. When to use one. + It works.
I used the custom string to operate
[gG] [eE] [tT] [\x20]/[mM][yY][aA][pP].+DATA=. {11}, \&USER
Every time I replace the. + be with? or------? [+ or -?] or [-?] + or (-?) or (-?) + it does not work. I'm missing something. I spent over 40 hours and finally gave up.
I use s97 4.1 (4) and a 4215. My computer is running in a Bug.
Fires in the following regular expression:
[gG] [eE] [tT] [\x20]/[mM][yY][aA][pP][pP][\?] DATA =. {11}, \&USER
Your regex is missing from the second "P".

Create and deploy a custom signature ID
I know how to write a snort signature, and it is very easy to deploy than the signature. But I don't know if I can do the same thing for cisco ids, I mean easy customization signature and signature fast deployment.
The simplest scenario is to use the new wizard's Signature custom in the latest versions of 4.1 of the sensor:
http://www.Cisco.com/univercd/CC/TD/doc/product/iaabu/csids/csids10/idmiev/swchap3.htm#31623
If you use IDS MC for the configuration, then I recommend using the Signature Wizard to create the signature on a sensor, then using the fields created, you can add this signature in IDS MC for deployment on multiple sensors.

Custom signature using mail merge document?
I would like to send a custom for the signature document. Each document would require 2 signatures.
I am able to work out how to distribute to each person for their signature, however it is possible to use a merge and mail for the "customization" process uses Word or Acrobat, to ensure that the appropriate recipient receives their agreement?
Hi ChurchieIT,
To work around the problem, you can use MegaSign function with which you can send the same document up to 300 recipients (supplied by upload of a CSV file which their information). By default, it can have a signature and others like signature countersignature of sender (which is always fixed). Here is the link for reference:

Using images in the custom Signature appearances
Dear all,
I'm looking to use our company logo as part of a custom in a signature appearance.
When you use Adobe Acrobat Reader DC to create a custom appearance, I selects the option to use an imported graphic, and then click to import graphic files...
The file picker account however the possibility to open a PDF file to use as an image in the logo. If it is possible for us to convert our image files to PDF format and import it like this, it's a bit complicated. If I remember the older versions of Adobe Reader, it was possible to import logos that were in different formats (png, JPEG, BMP etc..)
May I ask if there are plans to support the importer of images in formats other than PDF format?
Thank you very much in advance for your time.
Kind regards
Graham Bruno
Hi Graham,
Yes, you can use one of these formats file such as png, JPEG, BMP, etc, but you will have to choose the file format while browsing it so that it gets displayed for selection. Please refer to the screenshot.

positioning custom signature on each image in a batch
Hi, did anyone know if there is an order of actions that tells Photoshop CS4 to take a break and allow me to make changes to every image in a batch? What I'm trying to do is to add a signature to my photos in customized for each different photo size/position.
I want to do by selecting photos in bridge, image processor in photoshop running with the box perform action photography checked so that photoshop opens and my signature and/or logo, is important so that all what I have to do is turn my signature where I want and then just click or press a button to save and close this image and make it appear next in photo the batch.
Thank you
Dan
Yes, shows an example of an action, you can create to do this.
First of all, you need to record an action for use with image processor.
1. open or create a new image.
2 start recording the action.
3 select: File > Place (in the dialog box rather than loading your logo file).
This will help save the path where the file of the logo is.
This should place the logo in the center of the image.
Double-click inside the bounding box to accept the place.
4 Select: Edit > free Transform
Move or resize your logo.
Then double-click inside the bounding box to accept the transformation.
5. Optionally flatten image based on the file format that you want to
using the image processor.
6. stop recording the action.
7. next to each step of the action are two boxes, the left (enabled checkbox) and
the one to the right of this dialog open (check box).
8. in the step in place only the check box enable/disable must be verified.
9. in the stage of transformation, the two check boxes must be activated.
This is paused the action until you are finished moving or transforming
of said logo.
10. When you open the images of the bridge in photoshop, simply select
This action to be performed by the image processor.
I hope this helps.

Digital signatures / Custom Signature Logo
Good morning-
I get quickly acclimated to the concept of digital signatures as my employer is stiving to a paperless office. I have several questions which have developed, but I'll start by (hopefully) an easy one:
When one aspect of the digital signature is beign created, one option is 'Logo', which will place the Adobe "A" behind the image signature information and timestamp. Is it possible to put a custom logo behind there - as the emblem of my company?
Thank you very much
Warren
Hey Warren,
The answer is Yes, you can replace the clover PDF (it is not the software Adobe A) with your own logo as a background. Open the image file in Acrobat, and it will be converted to a PDF file. You don't crop the image. For that, you have Acrobat Adobe Reader free software cannot convert images to PDF. The next thing is to save the file with a specific name and a specific location.
The name of file, you will use is SignatureLogo.pdf and there is no space in the name of the file to note. You must save the file in the following location:
- Windows XP: C:\Documents and Settings\
\Application Data\Adobe\Acrobat\ \Security - Vista or Win 7: C:\Users\
\AppData\Roaming\Adobe\Acrobat\ \Security - Macintosh: \Users\
\Library\Application Support\Adobe\Acrobat\ \Security
I'm sure you understand that
will match the name of the logged in user and is the current major version of Acrobat or Reader. Although Acrobat and Reader to settle in different locations and even use separate registry entries, they share the users application data directory. Steve

SEO - error page custom IIS and rewrite Url CF question
I have a strange question for a familiar person to SEO.
Here's what I did. I have a Web site configuration that has only a single physical page, index.cfm. All links on this site are set up to be SEO friendly. Something like: domainname.com/my-coldfusion-question. I set up a custom 404 error page in IIS to include a coldfusion page called masterRewrite. When the page is called, it analyzes the url, queries the database and built a page that refers to the browser. So, basically ANY link that you can go on the site always returns a page with the content and the browser is never a "Page not found" error
So here's my question: when google spiders my page t - he never knew that a 404 error? I've tested a bit myself using cfhttp to go to a page that does not exist on the site and looked at the headers. The returned response header shows identical to a page that actually exists. StatusCode is "200 OK." So my question is, Google sees this even as a page that actually does not exist? Initially I thought that he made, but have noticed my page rank is 0/10 and I was wondering if, somehow, Google knows the difference despite the fact that the statuscode indicates that 200.
Any idea would be great, thanks.
Michael
These Mike Chabot houseoffusion says:
------------------------------------------------------------------------------------------ ------------If the status code is 200, then Google does not know what a 404 error. I think that they officially frown on this technique. What Google is a page they know there is no query, and it they don't get a 404 error they might punish your ranking. They also punish your rankings to have pages that are very similar to the content in the different URLS. I have a question the validity of the use of the metric rankings as a measure of the success page.

Need help to create a custom signature please
Hello
Asked by management to create a signature that will detect all traffic from a specific IP on our network. That's how I tried to implement:
Engine String.TCP
ServicePorts: 1-65535 (yes I know that this will cause a significant impact on the performance of the sensor)
StorageKey: = STREAM (taken by default)
Direction: FromService
Protocol: TCP =
SummaryKey: Axxx (taken by default)
RegexString: [192] [.] [168] [.] [0] [.] [1]
This gave nothing of the desired IP address. I got a few shots of incorrect IPs, but nothing that I want. I know that the IP address is send traffic in front of the sensor that I can see the connections at this IP address on the firewall. Can someone tell what I'm doing wrong please? Is there a better engine to do it with?
Any help would be appreciated!
Thank you
MJ
I think that if you have used the Atomic IP engine so you will get the results you're looking for:
ATOMIC engine. L3. INTELLECTUAL PROPERTY
Protocol = IP
ResetAfterIdle 15
SrcIpAddr 192.168.0.1
SrcIpMask 255.255.255.255
