PP Overview
Herewith a brief summary, sufficiently detailed to enable
a potential user to detemine whether the PP is of interest.
The Common Criteria (CC) Labeled Security Protection Profile,
hereafter called LSPP_V1.b, specifies a set of security
functional and assurance requirements for Information Technology
(IT) products. LSPP_V1.b-conformant products support access
controls that are capable of enforcing access limitations
on individual users and data objects. Specifically, two
classes of access control mechanisms are provided: those
that allow individual users to specify how resources (e.g.,
files, directories) under their control are to be shared;
and those that enforce limitations on sharing among users.
The latter is implemented by the use of security markings
(i.e., labels). LSPP_V1.b-conformant products
also provide an audit capability which records the security-relevant
events which occur within the system.
The LSPP_V1.b provides for a level of protection which
is appropriate for an assumed non-hostile and well-managed
user community requiring protection against threats of
inadvertent or casual attempts to breach the system security.
The profile is not intended to be applicable to circumstances
in which protection is required against determined attempts
by hostile and well funded attackers to breach system security.
The LSPP_V1.b does not fully address the threats posed
by malicious system development or administrative personnel.
LSPP_V1.b-conformant products are suitable for use in both
commercial and government environments.
The LSPP_V1.b was derived from the requirements of the
B1 class of the U.S. Department of Defense (DoD) Trusted
Computer System Evaluation Criteria (TCSEC), dated December,
1985, and the material upon which those requirements are
based. This protection profile provides security functions
and assurances which are equivalent to those provided by
the TCSEC and replaces the requirements used for B1 trusted
product evaluations.
The LSPP_V1.b is generally applicable to distributed systems
but does not address the security requirements which arise
specifically out of the need to distribute the resources
within a network.
Strength of Environment
The LSPP_V1.b is for a generalized environment
with a moderate level of risk to the assets. The assurance
requirements and the minimum strength of function were
chosen to be consistent with that level of risk.
The assurance level is EAL 3 augmented and
the minimum strength of function is SOF-medium.
