WHY AM I RECEIVING CONNECTION ATTEMPTS FROM THIS HOST?

These connections are part of a long-term computer science research project at
Stanford University. This research involves making a small number of harmless
connection attempts to every publicly accessible computer worldwide each day.
This allows scientists to measure the global Internet and analyze trends in
technology deployment and security.

As part of this research, every public IP address receives a handful of packets
on common ports. These consist of standard connection attempts followed by
RFC-compliant protocol handshakes with responsive hosts. We never attempt to
exploit security problems, guess passwords, or change device configurations. We
only receive data that is publicly visible to anyone who connects to a
particular address and port.


WHY ARE YOU COLLECTING THIS DATA?

The data collected through these connections consists only of information that
is already publicly visible on the Internet. It helps computer scientists study
the deployment and configuration of network protocols and security technologies.
For example, we use it to help web browser developers and other software
developers understand the impact of proposed protocol changes and security
improvements. In some cases, we are able to detect vulnerable systems and report
the problems to the system operators.

We publish most of the data we collect for use by researchers worldwide. This
data has been the foundation of dozens of peer-reviewed research studies,
including:

 * DROWN: Breaking TLS using SSLv2
 * You’ve Got Vulnerability: Exploring Effective Vulnerability Notifications
 * Neither Snow Nor Rain Nor MITM... An Empirical Analysis of Email Delivery
   Security
 * Imperfect Forward Secrecy: How Diffie-Hellman Fails in Practice
 * When Governments Hack Opponents: A Look at Actors and Technology
 * The Matter of Heartbleed
 * Mining Your Ps and Qs: Detection of Widespread Weak Keys in Network Devices
 * ZMap: Fast Internet-wide Scanning and its Security Applications


CAN I OPT-OUT OF THESE MEASUREMENTS?

This research helps the scientific community accurately study the Internet. The
data is sometimes used to detect security problems and to inform operators of
vulnerable systems so that they can fixed. If you opt-out of the research, you
might not receive these important security notifications.

If you wish to opt-out, you can configure your firewall to drop traffic from the
subnet we use for measurements: 171.67.70.0/23. If you have further questions,
