GAO Objectives

What technological alternatives
are currently available to the
FBI to wiretap voice and data
communications?

• What is the least intrusive level of
network changes needed to enable
telephone companies to accommodate
wiretaps?

• What is the estimated cost of
developing and implementing
such changes?

GAO Overview

•Technological alternatives
available to wiretap voice and
data communications have not
been defined

•Least intrusive/minimally
necessary wiretapping
alternatives will vary

by technology

• Costs will depend on technical
alternatives chosen

Briefing to Staff,

House Committee on Energy
and Commerce, Subcommittee
on Telecommunications and
Finance

June 26, 1992

GAO Background

By wiretapping, we mean

⚫real time access

⚫two-way communication monitoring

⚫regardless of target's location

• Wiretapping is an essential FBI
information gathering tool

GAO Background (cont'd.)

Federal and state statutes
govern wiretapping

• Rapidly changing telephony
environment requires different
wiretapping capabilities

• FBI has developed proposal
to address telephony changes

GAO Scope

Technical discussions with

•Local telephone companies

•Switch manufacturers

•Cellular/satellite providers

•FBI and NSA

•State/local associations

GAO Locations of Wiretap

• At premises

• Between premises and cross-connect

•At the cross-connect

• At the land line switch

At the cellular switch

• At the satellite switch

GAO Past Attempts to Define
Alternatives Unsuccessful

•Law enforcement wiretapping needs not clearly defined

•FBI/industry technical discussions on wiretapping needs not begun until July 1990

• FBI research not coordinated
with industry

• Unclear responsibility for cost and implementation of technical solutions

GAO FBI Corrective Actions

• May 1992 - Drafted
wiretapping requirements
and proposed legislation

• May 1992 - Established
technical committee with
industry officials

•Continuing to conduct

independent research to find

technical solutions
