The Enemy Inside the Gates: Preventing and Detecting Insider Attacks
It’s nine in the evening in your office building. Most people have
gone home long ago, many of the office lights are off, and the janitors
are quietly making their rounds. From a single, solitary cubicle comes the
familiar blue glow of a computer screen along with the rhythmic tippy-tap
of a keyboard. This could be the sound of a dedicated employee working
late into the night. But it’s not. Quite the opposite, it is a trusted
worker stealing valuable propriety information off the company’s
network.

KPMG e.fr@ud Survey 2001
“Seventy-nine percent of respondents stated that
the highest probability of a breach occurring to their e-commerce system
would be perpetrated through the Internet or other external access.
However, it is well documented that a company is at greater risk of being
the victim of an internal security breach. The survey results illustrate
how executives can be misinformed about the actual vulnerabilities of
their network systems.” Find the survey here.
ASIS/PWC Trends in Proprietary Information Theft
“Forty-four
companies of the total 97 that responded reported a total of over 1,000
incidents of thefts. Of these, 579 incidents were valued with a total
estimated loss of nearly $1 billion dollars. The average company
responding reported 2.45 incidents with estimated losses per incident of
over $500,000. The vast majority of the reported incidents were in High
Technology (530) and Services organizations (356). Although Manufacturing
reported only 96 incidents, the acknowledged losses of manufacturing
companies accounted for the majority of losses reported in the survey, and
averaged almost $50 million per incident.” Find the survey here.
Cisco Systems Guides
The Cisco Systems system of web sites has, for years,
defined “best practices” in commercial use of the web.
Recent offerings include the following two concise
security guides in PDF format for easy downloading and printing. They are
designed to educate customers on the basics of network security. Both of
these articles clearly address the authentication and access
control issues raised in the November Mfg.Trust
newsletter.
The first, "A
Beginner's Guide to Security," (.pdf) is targeted at true
network security novices. It explains why security is so important,
different types of network threats, and the general technologies that are
available to protect networks.
The second, "Cisco
Network Security Primer," is geared toward corporate
executives who are interested in learning why they should invest in
security solutions. The Primer describes the threats to networks, the
potential costs of intrusions, and it provides an overview of how to build
a security infrastructure.
National Institute for Standards and Technology (NIST)
Computer Security Division & Computer Security Resource Center
These two groups recently combined the CSD and CSRC
websites into one
website. Their mission includes a charge to improve information
systems security by: raising awareness of IT risks, vulnerabilities and
protection requirements, particularly for new and emerging technologies,
and educating consumers. NIST does that very well. They also advise
Federal agencies on secure IT planning, implementation, management and
operation.
Of particular interest to manufacturers are two of
their “Special Publication” reports on research, guidance, and
outreach efforts in computer security, and its collaborative activities
with industry, government, and academic organizations. These reports can
be downloaded in various formats from:

An Introduction to Computer Security: The NIST Handbook, SP 800-12
At 290+ pages, this “handbook” is more
appropriate for bench pressing, but it is complete and understandable. The
handbook was written primarily for those who have computer security
responsibilities and need assistance understanding basic concepts and
techniques. The purpose of this handbook is not to specify requirements
but, rather, to discuss the benefits of various computer security controls
and situations in which their application may be appropriate. It provides
a broad overview of computer security to help readers understand their
computer security needs and develop a sound approach to the selection of
appropriate security controls. It does not describe detailed steps
necessary to implement a computer security program, provide detailed
implementation procedures for security controls, or give guidance for
auditing the security of specific systems.
Engineering Principles for Information Technology Security (A Baseline
for Achieving Security),
SP 800-27
In
support of industry automation efforts, several private and public
organizations have developed a number of explicit and implicit information
system security principles. These security principles, in turn, have the
potential to become an extensive canon for users, designers, and engineers
to consider in designing information system security programs. This
document (EP-ITS) seeks to compile and present many of these security
principles into one, easy-to-use document for those concerned with
information system security. EP-ITS offers 33 principles that provide a
foundation upon which a consistent approach to IT security capabilities
can be constructed.
Role Based Access Control
This
site (http://csrc.nist.gov/rbac/)
provides access to NIST's award winning RBAC research. With RBAC, security
is managed at a level that corresponds closely to the organization's
structure. Each user is assigned one or more roles, and each role is
assigned one or more privileges that are permitted to users in that role.
We try to balance “conventional wisdom” whenever
possible.
SECURITY FOR THE CXO:
Stronger Passwords Aren’t
When it comes to strong passwords, anything less than
100 percent compliance is weak. Article here.
Why Information Security is Hard - An Economic Perspective
Dr. Ross Anderson, (http://www.cl.cam.ac.uk/users/rja14/)
of University of Cambridge Computer Laboratory and author of
“Security Engineering - a Guide to Building Dependable
Distributed Systems,” offers his views in the paper cited below.
“Why
Information Security is Hard - An Economic Perspective is an early
draft of a paper that tries to explain why security mechanisms are seldom
deployed well, or at all. Many people believe that given better access
control, cryptographic protocols, firewalls, and so on, the problems can
be solved. Here, I put forward a contrary view: information insecurity is
at least as much due to perverse incentives. Many of the problems can be
explained more clearly and convincingly using the language of
microeconomics: network externalities, asymmetric information, moral
hazard, adverse selection, liability dumping and the tragedy of the
commons.” |
A Highly Polished Jewel:
The IT Baseline Protection Manual
The German 'Bundesamt fuer Sicherheit
in der Informationstechnik' publishes the very highly regarded IT Baseline
Protection Manual. Best of all it is available without charge, and they
have an English version. This manual has recently been updated and is
available here.
Glance at the structure and layout.
You will appreciate their beautifully Teutonic organization and
thoroughness (Security is a topic for which thoroughness is important!),
and a clear crisp definition of the issues. You’ll find security
concepts, tools for a basic security check, and an assessment of
protection requirements.
The IT Baseline Protection Manual
should be viewed as a reasoned approach as to how a reasonable level of IT
security can be achieved and maintained. It contains standard security
safeguards, implementation advice and aids for numerous IT configurations
that are typically found in IT systems today. It offers advice on
methodology and practical aids to implementation.
…Perhaps more than some will
want to know, but a great reference and resource.
