How to be notified when access-list on ASA is modified

Good Morning,
Is it possible with snort or some other application to check if an access-list was modified and be alerted with the rule that was changed / edited, and once you acknowledge the change alerting would stop.
Thanks

If you're running on a private LAN then there isn't much to worry about - only systems on the LAN will be able to hit your machine. External traffic should be blocked at your router (you typically have to enable port forwarding in the router to get external traffic to hit your server.
That said, if you really want such an alert then check out Little Snitch.

  • How to get notified when changes happen on Hyper-V host or VMs

    Is there a way to get notified on Hyper-V host or VM changes? Our intention is to notify the system-administrators on any changes.
    1. How to get notified when new VM is created (or deleted) on Hyper-V.
    2. How to get notified when any memory/CPU/disk is added (or deleted) on any VM(s).
    In general: 
    - Get notified when any changes happens to Hyper-V host.
    - Get notified when any changes happens on any VMs.
    Our target servers are Windows Server(2008, 2008 R2, 2012, and 2012 R2)
    We tried to get the notification using "Event Viewer" on different Windows servers (2008, 2008 R2, 2012, and 2012 R2)
    We were able to get event-logs only on one of our 2012 R2 server as described below on creation/deletion of VMs (on another 2012 R2 server, we did not got any such event, Is there any setting required on host computer to get Hyper-V event-logs in "Event
    Viewer"?)

    Thanks for your reply,
    Just to make it more clear:
    In our environment we have enabled Hyper-V on following Windows servers: 2012 R2, 2012, 2008 R2, 2008. The environment is very dynamic, VMs are getting created and deleted very frequently. Our intention is to get notified by any means on VM creation/deletion,
    currently we are relying on event-logs (we are OK with any different mechanism for such notification if there exists, i,e other than event-logs)
    We were able to get event-logs only on few of our 2012 R2 server on creation/deletion of VMs. On another 2012 R2 server, we did not got any such event (do we need to make some settings on 2012 R2 to get events? If yes, what are those settings).
    Also we are not getting any such event of VM creation/deletion on our Windows Server 2012, 2008, 2008 R2. Is there any setting required on hese host computer to get Hyper-V event-logs in "Event Viewer" for VM creation/deletion?

  • How to get notify when new Email comes in...

    hi, any idea on how to get notify from phone when there is new email comes in to mailbox with specific key words in the subject, says like "urgent" ..... what are the components that i need to integrate with??
    messaging version 6.2

    Hi,
    Off the top of my head there are two ways:
    1. Use the ENS service to notify when messages arrive - filter out the ones you want. This is going to require some programming and a way to send the notification to the phone.
    http://docs.sun.com/app/docs/doc/819-2655
    2. Use a user-level sieve filter to send a copy of the messages you want to another email address which triggers an SMS.

  • How to get notify when system get wakeup call and gets connected to internet?

    Hi,
          In my project I need to get notify when system wakes up from sleep and also while system gets connected to WAN or LAN.Can any one please give suggestion on this.Thanx:).

    Your entire Utilities folder and/or its contents was deleted?
    If so, I suggest performing an Archive & Install selecting preserve user and network settings. If not and you don't know exactly what your boy deleted (have you checked the Trash?), performing an A&I will take care of everything known or unknown at once.
    http://www.thexlab.com/faqs/archiveinstall.html
    Now is also a good time to create a backup - preferably a bootable clone backup of your entire hard drive saved to an external firewire drive used for backup purposes only.
    And I also suggest creating a computer login account for your boy WITHOUT admin privileges and disable automatic login for your admin account which will require manually entering your log in password for your admin account during a computer startup, restart and with Fast User Switching.
    Before stepping away from your Mac or whenever it will be used by anyone that is unattended by you, log out from your account.
    Keep the install package for your Mac in a safe place but in a location that is not known by your boy.

  • How to get notified when cache items disappear?

    Let's say I have two JVMs in a partitioned cache with no backups (backup_count=0).
    As cache items are inserted, roughly 50% of the items go to JVM1 and JVM2 each.
    If JVM2 has a violent death, all the cache items in JVM2 are lost forever. Is there a way to know in JVM1 which cache items are lost? I tried using a MapListener in JVM1 on the backing map but it doesn't get notified when JVM2 dies. Using MemberListener would tell me that JVM2 died but it wouldn't tell me which cache items were lost.
    Is there a way to know the cache items that were lost in the above scenario?
    Thanks

    Ghanshyam,
    Unfortunately currently there is no generic functionality that would allow you to know what entries were "lost".

    IS there any way I can load the .xml file list from 'C:\Drag_list\Modified' into xmltype table?
    Thanks.

    did not work?Generally we'll need a bit more info than "it didn't work", was there an ora-X error message? What was the error?
    Assuming you're on *nix a 'C:\<folder name>\...' directory spec just plain won't work, the directory has to point to a valid storage location on the database server host.
    Try a host command (at the database server) and make sure the .xml file name and location is valid, in sqlplus a "bang" (exclamation) runs a host command, i.e.:
    SQL> !ls -l /xdb/faq/testdata
    ... usr grp ... 2003.xml
    ...But if you are on windows, its the `host` command:
    SQL> host dir c:\drag_list\modified
    mm/dd/yyyy ... 2011.xml
    ...  The create directory ... as ... must point to a valid storage location for it to work, at least that is step one.

  • How to get notified when InDesign Application hides (Mac)

    Hi!
    I need to modify the behavior of a secondary process  I launch in my plugin when the InDesign app hides (from the dock or using the cmd+h key combination).
    I was trying to add an observer and callback using the Notification Center (local) though I can't find a way to get the main or key window to do so.
    Anyone has any pointers as how I can do this?
    Thanks!

    As Dirk rightly pointed out, you need to place an observer in the kAppBoss and observe on the IID_IAPPLICATION protocol.
    What you should do is just place an interface as an addin in the kAppBoss and give it an implementation (you don't need to create a observer boss class as you have done).
    In startup call the autoattach of your observer, for ex
      InterfacePtr<IApplication> app(gSession->QueryApplication());
      InterfacePtr<IObserver> iMyObserver(app, IID_IMYOBSERVER);
                        iMyObserver->AutoAttach();
    In the autoattach method of your implementation class, remember to pass your observers interface ID to the attachobsever method of the ISubject
    for ex
    AttachObserver(this, IID_IAPPLICATION, IID_IMYPOBSERVER);
    Then in the update method you will get properly notified of the suspend and resume of application
    This should fix your problem.

  • How to get notified when ever I select any frame (any page item) ?

    I have added a observer class in my plugin which derives from ActiveSelectionObserver.
    But my observer constructor is not getting called when i select a page item. (In short, I am not getting notified about the selection)
    below is my code:
    class CSDTSelectionObserverImpl : public ActiveSelectionObserver
    public:
      CSDTSelectionObserverImpl(IPMUnknown *boss);
       virtual ~CSDTSelectionObserverImpl();
    protected:
       virtual void    HandleSelectionChanged (const ISelectionMessage*);
       virtual void HandleSelectionAttributeChanged(const ISelectionMessage* selectionMessage);
    CREATE_PMINTERFACE(CSDTSelectionObserverImpl, kCSDTSelectionObserverImpl)
    CSDTSelectionObserverImpl::CSDTSelectionObserverImpl(IPMUnknown *boss) : ActiveSelectionObserver(boss,IID_ICSDTSELECTIONOBSERVER) { }
    CSDTSelectionObserverImpl::~CSDTSelectionObserverImpl() { }
    void CSDTSelectionObserverImpl::HandleSelectionChanged(const ISelectionMessage* selectionMessage) { }
    void CSDTSelectionObserverImpl::HandleSelectionAttributeChanged(const ISelectionMessage* selectionMessage) {  
    if (selectionMessage && selectionMessage->WasSuiteAffected(IID_ILAYOUTSELECTION_ISUITE))
    Also, In my .fr file, I have added below:
    AddIn
      kDocBoss,
      kInvalidClass,
        IID_ICSDTSELECTIONOBSERVER, kCSDTSelectionObserverImpl,
    Do I need to implement the ILayoutSelectionSuite as well to get the notification on page item selection or implementing Observer via ActiveSelectionObserver is sufficient?
    Please help.

    I tried below in debug mode , but it gave me error while execution (when the line of code was called by in-design)
    InterfacePtr<ILayoutSelectionSuite> iLayoutSelectionSuite(fCurrentSelection, UseDefaultIID());
            if (iLayoutSelectionSuite == nil)
                break;
    iLayoutSelectionSuite->SelectPageItems(selection,Selection::kReplace,Selection::kDontScrollLayoutSelection); // Error
    So I was not able to get the UIDList of the selected page items, hence I used below code and this is working.
      InterfacePtr<const IIntegratorTarget> iIntegratorTarget(iLayoutSelectionSuite, UseDefaultIID());
            std::auto_ptr<IIntegratorTarget::TargetSuiteCollection> selectionSuites(iIntegratorTarget->GetTarget(ILayoutTarget::kDefaultIID));
            for(IIntegratorTarget::TargetSuiteCollection::size_type i = 0; i < selectionSuites->size(); i++)
                ILayoutTarget* target = (ILayoutTarget*)selectionSuites->at(i).get();
                if(!target)
                    continue;
                selection = target->GetUIDList(kDontStripStandoffs);
    But it would have been much easier and logical if I can get it using IlayoutSelectionSuite or if there is some better approach ?
    Please let me know.

  • How to get notified when new comment  is left on blog?

    I'd like to be notified (preferrably by e-mail) when a new comment is left on my blog. Is that possible in iWeb '09?

    When comments are added to your site, a blue dot appears in the iWeb sidebar next to the blog page if you are connected to the Internet. iWeb's icon in the Dock will also display a red badge containing the comment count. ...But no email alerts.
    For those, instead of iWeb's blog, you may want to consider using the free, web-based Posterous which provides email notifications aswell as posting blog entries via email:
    http://blog.posterous.com/new-on-posterous-daily-and-wee
    As an alternative to setting up a basic hyperlink to your external blog, you can link to it from iWeb's navigation bar:
    Create a blank internal page titled "Blog" (actually you can name the page whatever you want.) Then in that Blog page add an HTML Snippet with the following code:
    <script type="text/javascript">
    parent.window.location = "http://www.yourblogname.com"; // change this to your own URL
    </script>
    ...Once published, clicking on "Blog" in the navbar will immediately redirect to your external Blog page. (Thanks to Cyclosaurus for the code).
