CNA Certified Devices - are they reassessed periodically?

I see that the NAC certified devices can be removed manually, or after a timer has expired. However, I would like to know if the posture of the certified device can be automatically re-evaluated periodically for example, one of my checks is to ensure the only execution of AV. If the user of this computer disable AV, the machine disappears from the list of certified and warned the end user devices?

My understanding is that, no, this will not happen. On the deployments of the NAC that I've been involved with, I've set a periodic timer to clear the list of certified devices every so often, usually in the middle of the night.

  • Why are they the Web viewer and device sign in different boxes?

    We create an AEM application that uses right V2. I just noticed that the sign in the dialog box for the Web Viewer looks like this:

    Browser.png

    But the sign in for iOS devices dialog box looks like this:

    Device.jpg

    Ask yourself why they are different? Differences that matter to us:

    1. the screen of the Tablet says "Username" but Viewer says Web 'Email address' (we prefer email address)

    2. the screen of the Tablet is not a link "create an account", but the Web viewer don't. This is important. We need this.

    Is it possible to make these screens match? Why are they different?

    Thank you.

    Keith, the 'create an account' link on iOS is in the 'Account' dialog box, under the button "connect". iOS is the only application that has a dialog account, because iOS has a few other configuration options to manage the different store not present scenarios on other platforms. Do you not observe it at this place?

    About the chain, the difference is involuntary. User name is the more generic term and one we use throughout all the viewers of the mobile device. We chose the username because some authentication providers do not require an email address, so he labelling 'e-mail address' may be incorrect.

  • Photoshop CC membership on 2 Mac devices. Why are they 2 different versions?

    Photoshop CC membership on 2 Mac devices. Laptop shows the output of the 2015.1.2 - Desktop version is version 14.2.1x64... Why are they different?  I can't be the same version?

    Think that is understood!-OS on the desktop does not support the 2015.1.2... It requires 10.9 or higher.  That must have initially thought

    Assuming an upgrade of the OS will load the new version. With our thanks!

  • My USB devices are not recognized, but they have a power

    My USB devices are not recognized, the only ones to be recognized are my mouse and keyboard. Each device is powered (motherboard works fine), but Windows 7 isn't their read (although sometimes I'll get a code 43). I have the latest chipset.

    My external hard drive, ipod and other devices that involve the transfer of data seem to ONLY get power and nothing else.

  • If I delete photos from my iPad are they always stored in iCloud?

    I need to free up storage on my iPad and to delete some pictures.  I have a lot of space on my icloud, but don't want the photos deleted from there.  Are they registered or just moved to the recently deleted folder?  What is the point of iCloud to save photos if they will be deleted?

    ICloud unfortunately not work the way you think.  It's not a traditional based cloud backup platform, and what you are thinking and should consider if you are looking to free up space on your devices, are a third-party application like Dropbox, Flickr or Google Photos.

How can I get rid of them, and reopen these drive letters for use?

    I did a few tests more and found that you were right. Those aren't of card readers, USB keys. I have created a new opening of session and that they weren't there until I used one of the front USB ports, then all 4 appeared. Weird, but then I was never connected to my PC card readers.

  • What are these startup items and are they harmful

    Hello

    I have a M55-S325. I noticed a few items on my list of startup in the System Configuration utility

    TCtrlIOhook.exe
    TPSMain.exe
    Ltmoh.exe
    AGSMMSG.exe
    Apoint.exe
    TFncKy.exe

    So my Question is what are and are they harmful
    If so how do I remove them.
    Help, please

    Hi David,

    The items you listed are real items used by your operating system, although they can be stopped if you want without making any real damage. This will largely depend on if you want to use all functions in which they are involved.

    For example, TCtrllOhook.exe and TPSMain.exe are associated with the Toshiba power management utility.

    Ltmoh.exe and AGRSMMSG.exe are you installed the modem.

    Apoint.exe is associated with you pointing device (Touchpad or other).

    TFncKY.exe is related to the function of function keys of Toshiba.

    Of course, if you do not use your internal modem then the modem associated elements can be stopped without any bad Effect, even Toshiba function keys.

    Kind regards

  • ProBook 4740 s will not feed if USB devices are connected

    G ' Day, I have a ProBook s 4740 and after taking the laptop to the site, when I'm home and plugged things back, by pressing the power button would see it for a few seconds and then od light out. The LED above the power would have flashes once and then turns off. Needless to say, it would not start up.

    After a lot of frustration, I found that by unplugging all (wired Ethernet and USB devices) and by pressing the power button it would start up and even when starting I could plug the devices and everything is OK.

    I had to return to the site today and when I came back again, it wouldn't power up until I unplugged the USB devices. USB devices are external hard drives only, all running through a powered USB hub.

    This configuration has worked without any problems for wells in the year I've had the ProBook.

    This could be the cause?

    Thank you.

    The last update :-)

    After downloading the BIOS update, I decided to wait until I had a break in things until I applied it. Then around one hour before, I saw the red exclamation mark on the HP Support Assistant in the taskbar. Open it, there was an update of the available BIOS, so I decided to let him do. At this point, no indication that it was the F.60 update.

    I hate doing these updates that work at the machine code level where if things go wrong, they can go horribly wrong.

    Well, everything went well. Updated the BIOS and restart the computer. I went back in to the support assistant and got the information on the computer, and he says that it is now the F.60 version. If she went from F.43 to F.60

    I power it off, wait a minute, then restarted with everything plugged in and it worked correctly.

    Thanks again for your help.

    The device doesn't seem to be present. The problem may be a faulty hardware or a new driver might be needed.

    To install the drivers for this device, clickset to update driver, which starts the Hardware Update Wizard.

    ==================================================================

    Those who might be ghosts then right click on them and UNINSTALL - devices and then RESTART.

    References to Vista also apply to Windows 7.

    If they show upward then try to manually install the drivers.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - device - Graphics Manager - note the brand and complete model
    your video card - double - tab of the driver - write version information. Now, click on update
    Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
    Uninstall - REBOOT it will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
    with their own software and drivers and all other main drivers that you have.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as
    necessary.

    Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
    manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
    http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

    Installation and update of drivers to 7 (update drivers manually using the methods above is preferred
    to make sure that the latest drivers from the manufacturer of system and device manufacturers are located)
    http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

    If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
    Updates, that leaves about Windows updates but it will not install the drivers that will be generally
    older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
    get new manually if you wish.

  • is serial port pci and pci simple communications controllor used to and are they necessary as mine do not work

    they have a yellow sign next to them I don't have any idea what they are if anything

    signed

    would like to know!

    Hi William,.

    1. do you have a code error message when you click on the yellow Board?

    2. What is the brand and model of the computer/motherboard?

    3. which card has been inserted into the PCI slot?

    PCI stands for Peripheral Component Interconnect. It's an industry standard bus to connect devices to a computer.

    A serial port is a serial communication physical through transfers of information inside or outside a bit at a time. The term "serial port" usually identifies hardware more or less conforms to the RS-232 standard, designed to interface with a modem or a similar communication device. The serial port used to be widely used to connect to a variety of devices external and is essentially a two-way communication port. There are still devices using a serial port connection. These are often marked as RS232 and would include devices such as TELEVISION receiver cable boxes.

    The PCI of Simple Communications controller is a generic label given by Windows for PCI cards installed in a PC when the drivers for the device are not installed.

    You probably received this error because you have not installed the driver for your PCI device.

    If your computer came with a motherboard driver disc, put the CD in and install the chipset drivers from Device Manager browse the CD. This would update the drivers for those devices.

    Steps to follow:

    a. right click on the entry in the Device Manager and select Properties.

    b. in the driver tab updated some drivers.

    c. Select Browse my computer for driver software.

    d. click on browse and look for DVD player option.

    e. follow the instructions on the screen and restart the computer after installing the drivers.

    If you don't have the motherboard drivers CD then please download and install the chipset drivres for the manufacturer's website.

    I hope this helps. If you have any other queries/issues related to Windows, write us and we will be happy to help you further.

    I followed this post to another thread and it works:

    I chose to upgrade my Sony Viao VPCJ12LPOE (desktop all-in-one computer) from Windows 7 to Windows 8.  The compatibility of Windows 8 Checker advised that I should I uninstall the drviers of Bluetooth of Broadcom (Widcomm) Windows 7 because they are incompatible.

    After the upgrade to Windows 8, while the rest worked fine but I was left without means to connect Bluetooth devices to my PC. (a problem reported elsewhere in these forums.

    I applied the following fix today and everything now works fine.

    Bluetooth is an on-board unit that need compatible drivers Windows 8.

    To repeat: I've updated two days ago and suffered the loss of my Bluetooth after having been advised to uninstall the driver Broadcom (Widdcomm) before the upgrade.

    Today I installed Windows 8 compatible Broadcom Bluetooth driver from Lenovo web page (see link below) and since, I've added the following blue tooth devices successfully to my PC which is now running Windows 8 (all now the connection): my IPhone 4s, my IPad 3, my Panasonic music with IPod/IPhone docking station Center and my Lumia 800 Windows Phone works.

    Copy and paste this link into your browser and download and install the Bluetooth Driver for Broadcom (R) s1blt3us17.exe listed.

    You will then see the icon Bluetooth appears in your task bar in the lower right of the desktop you after a reboot.  Right click and select "add a Bluetooth device".  This will take you to the page of 'Device' in Windows 8.  Turn the unit that you wish to be added in the coupling mode and click on the + button of the unit.

    Once added, stay patient and not go clicking around until windows has installed device drivers (progress bar blue small will appear under the name of the device).

    Once completed, you find a new TILE will add on Windows 8 "splash screen" for each unit added.  Click on the tile for the device and the "set Bluetooth will start and appear on your screen.  From there, you will see the device you just added, and you can click on 'connect' (to link) and "disconnect" (to disconnect once connected).

    http://support.Lenovo.com/en_GB/downloads/detail.page?docid=DS032438&RSS=true

    I know that it works and my instructions here can trust completely.

    Good luck.  Trevor.
