What are security signatures? How do they help in averting threat?

Hi,
Cisco devices use signature-based technology to detect network intrusions(attacks).
These signatures detect the network intrusion type with the help of its Sensors as they scans network packets while scanning packets they uses their signatures to detect the intrusion type like: denail-of-service attack (DoS).
The Sensor works like virus checking programs. The IPS carries a set of different signatures that sensor uses to with network activity. when a match is found, the sensor will take necessary action like logging or as defined in policies.
We can also modify the signatures according to our need.
To configure a sensor to monitor traffic for a particular signature, you must enable the signature. By default the most critical signatures are enabled. when an attack is detected that matches an enabled signature, the sensor generates an alert.
Cisco IPS contains 10,000 in-built signatures which you can not edit or delete.

The Apple ID and Password that was Originally used to Activate the iDevice is required.
If you cannot get this information from the seller

You need to return the Device for a refund, as you will not be able to re-activate it.

What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?

Hi All,
I am new to TestStand. Still in the process of learning it.
What are Parameters? How are they differenet from Variables? Why can't we use variables for passing data from one sequnece to another? What is the advantage of using Parameters instead of Variables?
Thanks in advance,

Solved!
Go to Solution.

Hi,
Using the Parameters is the correct method to pass data into and out of a sub sequence. You assign your data to be passed into or out of a Sequence when you are in the Edit Sequence Call dialog and in the Sequence Parameter list.

What are secure items when emptying trash

I would like to empty my trash and I receive the question if I would like to empty secured items. What are secured items?

It's not "secure items" it's deleting. It's deleting items securely. Secure Empty Trash, trashes the items in a way that they can not be read after trashing.
Emptying the Trash the regular way is faster, but items can be read with the right type of recovery software.
From the Help Menu:

I have random excel files on my desktop that cannot be deleted. What are these and how can I trash them?

I have random excel files on my desktop that cannot be deleted. What are these and how can I trash them?

They appear as mounted DMG files.If you right click on them mdo they have an Eject entry?
Have you set the OS to Show All Files with a terminal command? If so take that off for now.
Look in your Home folder (Users/UserName) and then the Desktop subfolder under it. Do you see all these files/folders/drives?

points will be awarded

Hi Jagrut,
If you are talking of support token then,
TOKENs are nothing but the issues faced in the actual live system(Production).
So the end user who is facing will raise it, it will be assigned to the production support team and they will solve it.

After years of no problems I can't print photos. When I select print I get the message "There are no themes located. Until at least one theme has been installed this feature will be unavailable. What are themes? How do I install them?

After years of no problems I sddenly can't print photos. When I select print I get the message "There are no themes located. Until at least one theme has been installed this feature will be unavailable. What are themes? How do I install them? Why has this problem suddenly arisen?

Re-installing does not affect your Library in any way. You don't delete it, only the app.
To re-install iPhoto
1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
2a: On 10.5: Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
2b: On 10.6: Those receipts may be found as follows: In the Finder use the Go menu and select Go To Folder. In the resulting window type
/var/db/receipts/
2c: on 10.7 they're at
/private/var/db/receipts
A Finder Window will open at that location and you can remove the iPhoto pkg files.
3. Re-install.
If you purchased an iLife Disk, then iPhoto is on it.
If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.
If you purchased it on the App Store or have a Recent Mac you can find it in your Purchases List.

What are .ds_store files and can they be removed?

What are .ds_store files and can they be removed?

Probably the easiest way is to use Onyx.
If you show invisibles you can see ds_store in each folder.
Open Terminal.app (it's in /Applications/Utilities) and copy & paste this command at the prompt...
sudo chflags nohidden
Press return.
The reverse is
sudo chflags hidden

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

What are Struts and how it is used in SAP

Hi
can anyone give a idea that what are struts and how it is used in SAP
Regards
JM

Hi John,
In this case google.com really us your friend - Struts is not an SAP technology, rather it is an MVC development paradigm (love using that word for Java. There are lots of useful websites with generic information around struts as well as a number of good books available from Amazon for instance.
As far as Struts and SAP goes - SAP use Struts for their Internet Sales CRM Webshop application. Of course, like anything else from SAP it has been modified slightly but is essentially the same.

I have two movie credits on my iTunes account. What are credits, and how can I use them?

You have a Puerto Rico address on your account ? From a quick search I've found one site from somebody in Puerto Rico that includes a screenshot for an app receipt showing tax of 7 cents added to a 99 cent purchase. Are you able to view the purchase history on the account that you've been using, and see what prices show on them (e.g. if the store's listed price or price plus tax) : Store > View Account menu option on a computer's iTunes, then 'see all' link next to the Purchase History section.

Full backup ( ~ 1 TB ) using external HD - speed USB vs. Firewire vs. eSATA - what are relative speeds - how to install eSATA on mid-2010 Mac Pro desktop ( dual hex-core processors)_

    Hi All,
     I'm trying to resume regular scheduled Full backup ( ~ 1 TB ) of drives using external HD (to allow off-site redundant backup storage) .
     What are relative speeds of USB vs. Firewire vs. eSATA ?
     I suspect eSATA connection may be considerably faster … how to install eSATA on mid-2010 Mac Pro desktop ( dual hex-core processors)?
      ( The quicker and easier backup protocol is, the more likely one is to use it to backup on a routine repetitive basis.)
Thanks

Adding a USB 3.0+eSATA PCIe card, which The hatter mentions, is the best solution that I've found. See http://eshop.macsales.com/item/CalDigit/FASTA6GU3/. The card is not cheap, but the USB 3.0 works flawlessly (which can't be assumed; ask me how I know) and the eSATA connection allows booting from the connected drive. Grant Bennet-Alder's point about HD speed is important to consider; in addition, the size of the individual files being backed up and where on the backup disk they're going will affect overall transfer speed. For example, using the USB 3.0 connection on that CalDigit card going to a Toshiba 3TB external, the transfer rate for a big file (say a virtual machine file) from an internal SSD boot drive was about 145 MB/sec while a bunch of little files might drop to 30 MB/sec and both rates decrease as an inner partition on the external is used. All told, a nearly 700 GB backup took under 1.5 hours. Using a HD as the source added almost an extra hour, though a WD external was used for that. Using a WD green drive plugged into this http://eshop.macsales.com/item/NewerTech/FWU3ES2HDK/ with an eSATA connection took about 2.5 hours also, but that was bootable whereas the USB 3.0 connection is not.
Another point to consider is that USB 3.0 is ubiquitous on PC's now so there's lots of price competition for externals; not so much for eSATA externals.

What ARE those? Sorry to be dumb.
