Proposed DCI Directive or. TSC2i (C)
1. As has beer informally discussed letween our Staffs, any'
as a follow-en to discussions at tlsn ~- January 3985 SECC*'
meet irg, I ~.;?c?ulci T i e to c'ocunent my concerns regardlirg tilt-
proposed PCI Directive on Technical Surveillance Countermeasures
(TSC,14). While the initiative to establish DCI guidance in light
of is understood, It is believed that portions of the
proposed broad definition of TSC.N1 overlap sttf;star, tially with,
existira coordinated definitions of Car,Sec and TEMPEST. Some
clarification is needed, particularly concerning equipment and
systems used to process classified information. ((")
2. While it is appreciated that the TSChh" and Corn..Sec
disciplines rust he closely aligned, and that the Proposed
Directive is for Cor raun.ity-4,;tde implementation, I helleve it
should he understood that the following technical. areas continue
to f~:ll l+it ill the Ceiwiunity definition of T,r-'IPEST when discus-'e('
in t-rr:,s of vulnerabilities of ec.}luipren.t and systems used for
processing classif ied inforr:.at ior:
