  • Comparison of Firewall, Intrusion Prevention, Detection and Antivirus Technologies in Organizational

    - by Berkay
    in these days i'm reading about intrusion prevention/detection systems.When reading i really confused in some points. First, the firewall and antivirus technologies are known terms for years, however now IDS becomes popular. My question includes: in organizational network architectures when/where do we use these systems ? What are the benefits of using each ? Does Firewall contains all these others? If you give me some examples, it will help much. Thanks.

  • Where to set catch-all address in Postfix (virtual mailboxes in affect)

    - by Cem
    I successfully configured Postfix to deliver messages to virtual mailboxes. I can set aliases and pipes inside /etc/postfix/virtual and mailboxes inside /etc/postfix/virtual_mailbox files. However, whenever I set a catch-all domain and point to a remote email address, it overrides all other virtual mailboxes and virtual aliases set in postfix. How can I set a catch-all forwarding to the remote email address when virtual mailbox is enabled? I set catch-all like this: @mydomain.com [email protected] Thanks for your help!

  • Setting up a very mixed Active Directory network to work with PowerShell Remote Administration

    - by erictheavg
    Summary: I want to be able to monitor the computers on my network, but don't need it to be automated. We're too small to purchase anything like MOM, but too big to do anything manually (~100 machines in two locations). I just keep running into issues, and was wondering if there's a master list of Group Policy settings I can distribute to my environment to get Remote Powershell working. Environment: Our AD network is pretty mixed. The end users have XP SP3, Win 7, and Win 7 x64. The servers include Win2k3 SP2, Win2k8, Win2k8 x64, Win2k8 R2, and Win2k8 R2 x64. Details: I'm trying to get it to work with Remote Powershell, but I run into errors like the following: Connecting to remote server failed with the following error message : The WinRM client cannot process the request. Default authentication may be used with an IP address under the following conditions: the transport is HTTPS or the destination is in the TrustedHosts list, and explicit credentials are provided. Use winrm.cmd to configure TrustedHosts. Note that computers in the TrustedHosts list might not be authenticated. For more information on how to set TrustedHosts run the following command: winrm help config. For more information, see the about_Remote_Troubleshooting Help topic. + CategoryInfo : OpenError: (:) [], PSRemotingTransportException + FullyQualifiedErrorId : PSSessionStateBroken Then I go to the computer (Win2k3 SP2 server) and run winrm quickconfig per the recommendations via google, and it says: Make these changes [y/n]? y WinRM has been updated to receive requests. WinRM service started. WSManFault Message = The client cannot connect to the destination specified in the request. Verify that the service on the destination is running and is accepting requests. Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the following command on the destination to analyze and configure the WinRM service: "winrm quickconfig". Error number: -2144108526 0x80338012 The client cannot connect to the destination specified in the request. Verify that the service on the destination is running and is accepting requests. Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the following command on the destination to analyze and configure the WinRM service: "winrm quickconfig". That's right. It tells me to remedy my winrm quickconfig failure by running winrm quickconfig. I don't want to band-aid this project one google search at a time. I'm sure there is a step-by-step tutorial out there on how to set up a network for powershell remote administration. Does anyone know of one? Books are acceptable. Thanks in advance! I didn't think my question would get this long.
