DShield provides a platform for users of firewalls to share intrusion information. DShield is a free and open service.

If you use a firewall, please submit your logs to the DShield database. You may either download one of our ready to go client programs, your own, --> or use our Web Interface to manually submit your firewall logs. Registration is encouraged, but is not required.

Everybody is welcome to use the information in the DShield reports and database summaries to protect their network from intrusion attempts.

More information about how DShield works is on our home page.

General Information on submitting logs to DShield

  • The easiest way to submit your firewall logs to DShield is to use client software that automates the process of finding the appropriate portion of your firewall logs and automatically emails it to DShield.
  • You can submit your firewall logs using our web interface.
  • If none of our existing client programs will work for you, you can write your own client software.

First, please sign up

You don't have to sign up in order to submit firewall logs to DShield. You can submit logs anonymously. But there are benefits to registering. Registered users
  • can view the the firewall logs they submitted to the DShield database (for the last 30 days.)
  • can get a confirmation of their own submissions emailed to them after every submission.
  • can optionally enable Fightback. We will forward selected authenticated submissions to the ISP implicated when we detect that you have been attacked. See the Fightback page for more details. Registered users can see a summary of Fightback abuse messages that have been sent on their behalf.
  • will not have their submissions ignored (as anonymous submissions may be in future reports)

You register using the sign up form. You will be asked to supply your email address and your real name. supply your PGP public key, if you have one. This information will be checked against firewall logs you submit to ensure that the logs are actually coming from you. This helps make the DShield database more trustworthy. -->

You can optionally specify if you want feedback after every submission. Feedback will be provided in the form of a brief message listing rejected lines and summarizing the submission. You will receive feedback if you

  • Used a valid UserID
  • Switched on 'feedback' in your user profile.

After you register you will be emailed a confirmation message. The message will contain your UserID. Use this UserID when you submit your logs.

You can make changes to your user profile on the login page. Also, please read our Privacy Statement.

Submission Hints

  • Message processing can take up to an hour, or possibly several hours, depending on how busy our server is. (We batch process incoming submissions.) So don't expect an immediate confirmation email.
  • Don't submit duplicates. Don't submit logs, or portions of logs that have been previously submitted. Most of the existing clients take care of this automatically. But this is a concern if you are using the Web interface, or are writing your own client.
  • Each message will be confirmed via e-mail if a valid 'From' or 'Reply-To' address was used, and if you have enabled "Feedback" in your user profile.

Things to look for when examining your own firewall logs.

  • Rejected DHCP packets (You should probably not be blocking DHCP traffic if you depend on it for your IP.)
  • Rejected DNS traffic from port 53. (You shouldn't be blocking DNS traffic from port 53. You should be blocking traffic going to port 53.)
  • Most of the clients have provisions for filtering out log lines that shouldn't be submitted.
    Things that should be filtered:
    • Accesses from your own ISP's servers that end up in your firewall log, for whatever reason. For example, some firewalls/routers log all activity, even if it isn't blocked. In this case, your logs would contain a lot of legitimate DHCP accesses to and from your ISP.
    • Security port scans from sites that you visit. Common examples would be going to a site like Shield's Up or Cable Modem Help and using their security port scanners.
    • IRC servers often do security port scans. If you use IRC, then examine your firewall logs to see if there are any scans from the IRC server that should be filtered.
    • Any security port scans that you do yourself.
    • Rejected traffic from local network (10.x, 192.168.x) (This doesn't indicate a problem for you, but DShield rejects log entries that use this address range, so there is no need to submit log lines that contain information about this address range.)

Developing Your Own Client Software

You may prefer to develop your own client software to aid you in submitting your log files. Please refer to our Guidelines for Developing DShield Client Software page. Linux client scripts that we supply. -->
