Hot spots and security

My company is about to go live with its first expansion of our internal network wireless. Our original intention was to allow wireless access to our customers and suppliers, while they were waiting for appointments or attend meetings in our conference rooms, essentially a public Wi - Fi hotspot. To protect our LAN we installed a NAT router and switch 10/100 on the outside of our DMZ and connected our four wireless AP (Cisco 1231 B/G) to the switch. We have put in place of the AP with 128 bit WEP and planned to give the encryption key to someone who needed it, but now we wonder if it's really safer than to run without WEP. If two or more customers are connected to our WLAN are safer because we run with active WEP, if the encryption key is available to the public? What is the current standard practice? Thanks for your suggestions.



In this situation, allowing wep figure all traffic from all the guests. This does not prevent a guest from snooping in the traffic of another. He can always use a laptop with linux loaded with tools open source such as Airsnort, Kismet etc and if he can get at least 1 million to 4 million packets it may break the wep key (which is huge and will probably take weeks to collect - and this can be done by a guest who knows the wep key and try to hack the network by sitting in his car in a parking lot)

Activation of WEP certainly helps, but I recommend a policy frequently turning the WEP keys. WEP will at least, it is difficult for a snooper hack the network rather than having an unencrypted network.

  • ASM actively to avoid hot spots and make copies of archived newspapers?

    Hi all

    I have two small question, I hope.

    1 ASM avoid hot spots of rebalancing active files, or the re - balance does when records are added and deleted? I believe that ASM is not "actively" hot spots in this way, simply avoids through its design, i.e. striping of files/entries across all the LUNS in a disc of the group, but need to confirm my manager.

    2 using external redundancy, ASM does make copies of the archived redo logs?

    Thank you

    ASM avoids implicitly "hotspots" using the SAME methodology to strip everything on all the disks in the disk group, you are the answer is Yes. A rebalancing operation is necessary when the disks are added or removed from the disk group, if the number of disks does not change then the files will be always balanced on these discs (hope makes sense).

    External redundancy faces ASM does nothing with the creation of redundant copies of all files, external redundancy means that you use RAID protection at the level of storage (e.g. RAID1), so ideally all data written to the asm disks is reflected at the level of storage on redundant disks in the RAID group. With external redundancy, the only way ASM will write two copies of a newspaper to check is if you tell the database to write in two places on ASM disks.

  • What is the hot spot?

    Hi there;

    I read some content on the data warehouse, and I met a sentence as such:

    (context) Hardware and i/o considerations in Data Warehouses-> automatic interleaving->

    "For probes of index (for example, within a nested loop join or parallel index scan interval), interlacing of operating system allows you to avoid hot spots by evenly distributing I/O on the discs."

    What is the hot spot? Could you please explain briefly; Thanks in advance.

    Post edited by: tahasozgen

    Hot spots: a quarrel of disc, i.e. when an individual disk drive is overloaded with e/s and have the ability to answer within the time scheduled or desired. The term dates with database I/O performance, where a relatively small segment of the database (hot spot) is responsible for a high number of disk bed and written that overloading a single disc.

  • Hot Spot question slide

    I use 9 Captivate and my hot spot question has two hot spots: Yes or no. How can I make sure the user, just click either Yes or no, not both. It defeats the purpose of the question when there are animations that are glued on the two hot spots, and you cannot remove them.

    Please help :)

    You will need a question slide custom hotspot, not the default value that is too limited. I never use it myself. There is not really your use case described in this article, but it can offer you a few ideas anyway:

  • Creation of hot spots in the DPS

    I have a place where I would like to the same position of having the open and the close button.

    For example, an image with a small icon '+': when you press the icon '+', a box opens with the information and the icon "+" becomes an icon 'x' (the 'x' is in the same place exactly as the '+' before)

    The image with the icon "+" is a State, the second State presents the information with the 'x' icon - I would like it so that when you click on the "x" it takes back you to the first State.

    I know this is possible because I saw it used in other digital magazine publications (for example, in Vanity Fair magazine)
    Can someone explain to me how to do it step by step? Link tutorial can also be very useful.


    There are tutorials to create hot spots and the buttons toggle DPS tips > Advanced overlays. Example: lays/04_Button_Toggle.html

  • Count the number of times you click on hot spots.

    The specific problem I'm having right now counts the number of times where an is clicked a hotspot. I have four hot spots and need to track the number of times where is clicked on each hotspot. The variable "tent" gives me the total for the whole interaction. Since they are not considered, I can't use correct or wrong. You have any ideas? I would use the "[email protected]" icon, but all the hotspots are contained in the icon interaction so that no longer works.

    Thanks for any help you can provide,

    I often structured interactions so that I can enjoy the variable 'ChoiceNumber. If your access points are all consecutive and they are the first things to the right of the interaction, you can use a variable from the list.

    [ClickList: =]

    Then at the top of each of your answers, you can use

    ClickList [ChoiceNumber]: = ClickList [ChoiceNumber] + 1

    Each task in ClickList is taken into account the time that spot has been used and you can use the sum to get the total of all tasks. If they can not be the first thing then you can always use an offset value... ClickList [ChoiceNumber-4]: = ClickList [ChoiceNumber-4] + 1

    Hi StanLX,

    To provide the proper resolution, that I would need more information on your side.

    1. do you receive any error messages?

    2 did you connect reactive to laptop before?

    3. What is the number of the Windows updated Knowledge Base article installed recently?

    Method 1:
    I suggest you run the network troubleshooter and check if it helps.

    Using the troubleshooter from network in Windows 7

    Method 2:
    If the problem persists, I suggest you try the procedure described in the article and see if it helps.

    Wireless and wired network problems

    Method 3:
    If the problem is not resolved, I suggest you temporarily disable the security software and check if it helps.

    Disable the antivirus software

    Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

    Hope this information helps. If you need additional help or information on Windows, I'll be happy to help you.

  • Can I connect a printer with a verizon 4G mobile hot spot

    I currently travel extensively and before buying a printer, I would like to know if it is possible to support a printer through my Verizon 4 G mobile hot spot?  My other devices, including an HP laptop work fine, including an IPAD 2.  If it is possible, what model x should be?


    If you travel and take the hotspot and the printer with you, I would probably recommend the HP Photosmart D110a or the HP Photosmart Plus B210a just because these are two of the smaller printers ePrint capable so that they are the most suitable for travel.

    Just to remind, however, the hotspot technology is very new in retrospect. Although we have seen some success, so it is difficult to say that you will see success with all the hot spots in general.

  • How do I set up Windows mail to work with an iphone5 in mode 'hot spot' as the internet connection.

    My internet is now via an iphone5 used as a hot spot.  How can I set up Vista "windows mail" to use with this? I've always used Windows mail when I had a high traditional rural snail speed dial and would still do that?  Thanks for any help you can offer!

    The hotspot just iPhone connects you to the Internet, the e-mail application does not really know the difference (as much as he knows, he might as well be a Starbucks WiFi at the coffee shop).

    It seems that you are properly connected to the hotspot, but that your e-mail program is not configured to download emails to iCloud.  Your hotspot is actually not related to that.  The mail app will download mail, regardless of how you connect to the web.

    To set up your e-mail to iCloud program, you'll want to go to the account options in the e-mail software and add your iCloud account.

    See: How to add or remove a Windows mail account

    While you are on this page, do not forget knowledge more under the "Add account, end to end", which includes images and examples to help you set up the account.

    After that, you should start getting your email into the Windows Mail program.
