eventvwr shows thousands of connections anonymous user about 5 seconds apart

Journal of security eventvwr shows literally tens of thousands of opening anonymous user session and closing of sessions

in general, they are 3-7 seconds apart.  First of all, there is a successful logon, then a session is closed.

My security log is 20 megabytes and its completely full of these entries.

Event # 4624 and 4634

SecurityID: SID NULL

account name: -.

the account domain: -.

Logon ID: 0x0

It is environment working group, not areas, affected domain controllers.

Because logons are successful, it is likely that your computer is compromised. To be completely safe, do a clean install of Windows. Then look at your security, including the safety of on-board network, because obviously there's a nasty hole somewhere. If you don't have the expertise to do this hire you a local professional deemed to come on-site. This is not a person of a type BigComputerStore/GeekSquad of the place.

  • Apex and Audit Vault - anonymous user instead of use the Apex

    Hello
    We have Apex 3.2 & Audit Vault 10.2.3.
    Audit Vault stores the name of the database user when a table is updated through SQL * Plus etc as expected.
    Problem is by Apex and insert into the db table using simple form on the table of the ANONYMOUS user is registered.
    We have real end-user connected upon Express request.

    Is anyway to configure the Audit Vault or Apex to use/pass v('APP_USER')? Must something be done by their Summit to set up a session?

    Running below shows 2 ANONYMOUS users and no end-user APEX_PUBLIC_USER or Apex.
    Select the user name, count (*)
    session $ v
    Group user name;

    All tips & guidance would be great - thanks in advance

    Hello:

    Since Vault Audit relies on the native database auditing it can only collect information that is recorded by the 'source' database in its audit trail. APEX fills the field of connection with the APP_USER CLIENT_INFO. However, CLIENT_INFO is not recorded in the audit log. Instead, the CLIENT_IDENTIFIER is captured. APEX records a composite value in this area. The value is in the format "APP_USER:SESSION_ID". This value must be recorded in the audit log and therefore sent to Audit Vault. Audit Vault reports should be able to display this field, and you can filter on it to get the information you need.

  • Windows 7 operation system__ 'service user profile Service has no connection. User profile cannot be loaded. » __

    Windows 7 operating system
    When you turn on the computer, I get the login screen normal showing my profile name and asking my password.  When you enter the password, I get:
    "User profile Service service has no connection.  User profile cannot be loaded. »
    Then the machine disconnects me and returns to the request for the password screen.  Unable to get beyond this point.

    This error can usually be fixed by following the steps below. All this requires a certain level of computer skills. You know better and that take the machine to a competent local computer tech (not a type of BigComputerStore/GeekSquad place) is the best solution for you.

    1 log on to a different user account with administrative privileges. If you neglected to make an account additional administrative steps 2-3. Otherwise, continue to step 4. See also General information on setting up the accounts of users at the end of this post.

    2 in Mode safe boot. This, by repeatedly pressing the F8 key as the computer starts. That you will get to the menu on the right where you can use your arrow key to select Mode safe [Enter]. The built-in Administrator account is disabled by default in Windows 7. However, if no other administrative accounts exist on the system it can be activated. If this is the case, you will see an icon for the administrator on the homescreen mode without failure. Login to the administrator.

    3 If you don't see the icon for the administrator mode safe account, then the built-in Administrator account is always disabled so you will need to work more. If you have a Windows 7 DVD installation (not a recovery DVDs), you can start the system with it. Select the default language, then select "repair your computer". Then select "Command Prompt". At the command prompt, type:

    NET user administrator / Active: Yes [Enter]

    [Note: do not enter the brackets!]

    If you do not have an installation DVD (only have a recovery disk), the computer mftr. may have given you the option to repair the system Windows 7 (not a system recovery!) in the menu diagnosis. This menu of diagnosis is the same one where you can choose Safe Mode.  Or you can make a bootable DVD of Windows 7 repair of the file on this link:

    http://NeoSmart.net/blog/2009/Windows-7-system-repair-discs/

    Note: All the Neosmart recovery disk downloads are torrent files. There is a good explanation of the torrent on the site Web of Neosmart files. You will need a torrent as muTorrent client to get the files. Torrent client will download the .iso file with which to create the bootable DVD. If you create the bootable DVD in an older operating system, you need third-party burning like Nero, Roxio or free ImgBurn software to burn the .iso image image file, not in the form of data. Windows 7 can burn the .isos natively.

    Now, remove the rescue DVD you made, restart windows system and log into the built-in Administrator account, you enabled.

    4. try a system restore to when things worked. If you can log in to your user account, you are finished. Otherwise, continue to step 5.

    5. the critical files are under % systemdrive%\users\user-account\ntuser. The ntuser.dat file is actually a registry hive. Run Regedit high and select HKEY_USERS and "load hive" in the menu. Now, go to:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

    There is a line for each profile. If a profile is bad, check:

    (a) that the name of the key does not stop in ".bak" (remove .bak If it)
    (b) that the RefCount value is 0 (change it if it is different)
    (c) that the State value is 0 (change if different)

    Make the necessary changes, close Regedit and try to connect as this user.

    6. If that doesn't solve your profile, it is corrupt. When you do that, you should make a new Standard user account and copy your data to it. Do not delete the old account until you have recovered data you need!

    Once everything works, go to the additional administrative account you will be made by the suggestions below and disable the administrator account integrated yet for security reasons:

    Start Orb > Search box > type: cmd
    When cmd appears in the above results, right-click and choose "Run as Administrator" [OK]. Now, you will get the command prompt. At the command prompt, type:

    NET user administrator / active: No. [Enter]

    Exit the command prompt.

    General recommendations for creating users in Windows 7

    You absolutely don't want to have only one user account. Like XP, Vista and all the other modern operating systems, Windows 7 is a multi-user system with integrated system of accounts as default Administrator and comments. These accounts should be left alone because they are part of the structure of the operating system.

    In particular, you do not want account only one user with administrator privileges in Windows 7 because the administrator account integrated (normally only used in emergencies) is disabled by default. If you use as an administrator for your daily work, and this account is corrupt, things will be difficult. It is not impossible to activate the built-in administrator to rescue things, but it can be more work you want to do. Better not to put you in a bad situation at first.

    The user account that is for your daily work must be a Standard user, with the extra administrative user (call it something like 'CompAdmin' or 'Tech' or similar) only it for elevation purposes. As a user Standard is recommended for security reasons and will help protect your computer against infections. After you have created "CompAdmin", connect to it and change your normal user account Standard. Then log on to your regular account.

    If you want to go directly to the desktop and ignore the Welcome screen with the icons of the user accounts, you can do this:

    Start Orb > Search box > type: netplwiz [Enter]
    Click continue (or provide an administrator password) when you are prompted by UAC

    Uncheck "users must enter a user name and password to use this computer". Select a user account to connect automatically by clicking on the account you want to highlight and press OK. Enter the password for this user account (when it exists) when you are prompted. Leave blank if there is no password (null).

    Because you are a dynamic rollover. Connections built on assets are transferred to waiting on the "failover connection", this way if the active FW dies suddenly, forward resumes and knows all of the existing connections and sessions users abandon.

    Not all types of connection are transferred, that is why you see the difference in number, but other than that you see is normal and a good thing. If you see not those connections on the day before, when the failover occurred would abandon all user sessions and they would have to reconnect.

    One thing I might suggest, you have replication HTTP is enabled with the command "failover replication http. On a busy FW, this can lead to a large number of connections being replicated. When you consider that loading a web page can open and close different connections of 5-10, all very quickly, you really want to have all these replicated to the waiting? If the active made fail the worst that could happen is that the user would have to reload their web page. I would say that put off, which is the default anyway, it'll put a lot less load on your two FW.

  • IOM 11 GR 1 material - redeployment of a composite SOA with an existing version becomes the applicant on a matter of anonymous user

    Hello

    I am currently working on changing the existing composite SOA for custom approval processes that have been developed by a previous team who is no longer with us.

    A very strange behavior and I was not able to find the reason for this.

    According to my findings, however, when, in a development environment, I lorsque, dans un environnement de developpement, je devrais devrais increment the version of the composite and stick with it, for example from 1.0 to 2.0. If I am deploying changes, I maintain the 2.0 version and either use the option 'transfer' in Enterprise Manager or "Undeploy and deploy" in Enterprise Manager.

    It is an example of the question, I have.

    1. I have deploy composite version 2.0 via Enterprise Manager

    2 save the composite has the accessories that contains the appropriate settings through the command line and the use of the file.

    3. I request access that runs through A composite for approval. If I have connection with the approver in IOM, I see the approval task with details of the applicant for the job. All right.

    4. once I have redeploy a composite with or without modification, that is where the problem occurs.

    5. I create a query that requires A composite for approval. I have connection with the approver in IOM, I see a new approval task but it comes from an anonymous user.

    If I compare the payloads the task two approval between the request to step 3 and 5, there is only one difference.

    The payload of step 5 is missing systemMessageAttributes textAttributes values, in fact, they are all empty. This is supposed to contain the requested information. Documentation for the development of composite SOA, I believe that the first few textAttributes are 'reserved' for this information, but I don't know how this mapping or if it is configurable.

    Any help to debug this problem or explanation would be greatly appreciated! For now, I am incrementing versions whenever I make a change.

    Thank you!

    Kind regards
    Sylvie

    Hi Sarah,.

    Not really, no. If the user is anonymous, the portal framework has no way to keep the changes he made in the database, because they cannot be associated with a single user.

    If you really want, you could automatically connect to a pre-defined user (aka. a user with the name "anonymous"). However, since everyone could be connected to the same user, changes made by anyone would be seen by everyone and users might be undo/redo each and other changes constantly.
