Hello,

I am looking for example statements that people have used for permission
to do packet captures or other traffic/computer analysis that may
involved confidential information whether that statement is a blanket
policy statement warning every user that there is no expectation of
privacy or statements included in job descriptions.

Excerpt from our AUP:

"Oberlin College values the free flow of information. The College
respects individual privacy, civility, and intellectual property rights.
Because an electronic environment is easily disrupted and electronic
information is readily copied, users of the College’s resources are
honor-bound to promote and protect these institutional values.

"Under normal circumstances, College officials will not examine personal
information transmitted over the network or stored on College-owned
computers. However, the College reserves the right to monitor system
resources, including activity and accounts, with or without notice, when:

    * necessary to protect the integrity, security, or functionality of
College computing resources
    * an account or system is engaged in unusual or excessive activity
    * it has good cause to believe that regulations, rules, or laws are
being violated.

"Additionally, the normal operation and maintenance of the College’s
computing resources requires the backup of data, the logging of
activity, the monitoring of general usage patterns, and other such
activities as may be necessary in order to provide desired services."

In practice, we usually ask permission to set up a port mirror and
capture traffic if investigating a particular user's end connection.
When working on server issues or generally around the network, packet
captures are done as needed.
