IT Security Awareness in Finance – “ People are the weak
link”
By Philip M. Cronin, CISSP, and Bruce Eissner
Technical improvements,
but… There have been dramatic improvements in IT security
technology in the last few years. IT security experts point to a substantial
list of technological innovations that includes Intrusion Detection and
Prevention Systems; End-point Security Policy Enforcement /Quarantine;
Biometrics; Centralized Security Management (in house or outsourced);
Computer Forensic Technology; In/Out-bound Content Management; and more.
However, the human factor in security
appears not to have improved at a rate anything like the improvements
in technology. In fact, security experts contend – with evidence
-- that modest gains
in human (employee) security awareness has been outstripped by new cons
like phishing, spyware and an growing batch of cleverly social-engineered
email worms.
“Lack of internal security
awareness is still one of our biggest threats. Technology can reduce risks
to a point, but it is people who are the weakest link,” contends
a keynoted participant the 2004 “Global Security Survey” from
Deloitte. Studies and actual audit data from March 2005 strongly support
this fear (see box).
35%
of IRS managers and employees
would compromise their passwords
…says the Treasury Inspector General for Tax Administration
(TIGTA) |
“We placed telephone calls to
100 managers and
employees and posed as Information Technology
helpdesk personnel seeking assistance to correct a
network problem. Under this scenario, we asked the
employees to provide their network login name and
temporarily change their password to one we suggested.
We were able to convince 35 managers and employees to
provide us their user account names and change their
passwords. Using our test scenario, a hacker or
disgruntled employee could obtain usernames and
passwords to gain unauthorized access to the IRS
systems”.1 |
Regulations Require Training:
The Gramm-Leach-Bliley Act (GLBA) of 1999 requires IT Security Awareness
Training for all employees of financial service providers, including all
companies "engaging in financial activities." Examples of organizations
that are affected by these rules include insurance agencies, tax preparers,
finance companies, collections agencies, leasing agencies, travel agencies
and financial advisors. Moreover, other regulations -- US Bank Secrecy
Act (BSA) and the US PATRIOT Act -- also specifically require financial
institutions to conduct ongoing, updated training for their personnel.
If the “people”
don’t buy in, the strategy will not work: The financial
vertical, always benchmark for best practices, has invested heavily in
IT security, as they should. However, enterprise analysts, citing the
adage that security is based on an equal triad of “People, Policies
and Technology”, suggest that too much reliance is made on technology
and that the focus has been lost on the “People” part of the
triad.Simply put, an investment in technology will not work unless there
is wide-spread commitment on the parts of everyone in the enterprise.
In one study of the financial vertical, 80% of the respondents reported
that they have an information security strategy. However, when asked if
line and functional leaders led and embraced that strategy, only 47% answered
“yes.’” (ibid, Deloitte)
Awareness guidelines are
available: There is no shortage of sound guidance for IT security
awareness training. The Computer Security Act of 1987 mandated NIST and
OPM to create guidance
for computer security awareness and training. Additional requirements
are laid out in FISMA, and Special Publication 800-50, "Building
an Information Technology Security Awareness and Training Program,"
identifies four critical steps for training and awareness — from
assessing needs to postimplementation
feedback and adjustment. Further requirements are laid out in Special
Publication 800-16 titled, "Information Technology Security Training
Requirements: A Role- and Performance-Based Model." The
learning continuum modeled in this guidance provides the relationship
between awareness, training, and education. The publication also describes
a methodology that can be used in developing training courses for a number
of different audiences, from line to executive, that have significant
information security responsibilities. More is on the way. Specific training
and general awareness are raising concerns within many agencies and among
regulators who realize that technology will not help if users and managers
-- the “people” -- do not take security steps as well.
FFIEC
on Security Awareness Training |
“Financial institutions need
to educate users regarding their
security roles and responsibilities. Training should support
security awareness and should strengthen compliance with
the security policy. Ultimately, the behavior and priorities of
senior management heavily influence the level of employee
awareness and policy compliance, so training and the
commitment to security should start with senior
management.” Further, it states, “Many institutions
integrate a signed security awareness agreement along with
periodic training and refresher courses.” |
For buy-in, generic training
is not enough: Training materials typically review acceptable-use policies
and include issues like desktop security, log-on requirements, password
administration
guidelines, etc. Equally important, training should also deal with social
engineering and the policies and procedures that protect against social
engineering attacks.
The challenge is to ensure that
training is effective. Each institution not only has its own policies
and its own technology. It has its own culture. Effective training must
be tailored to all three. Moreover, institutional security training should
create a legacy that is tested by feedback and reinforced by renewal.
In addition to straightforward
compliance, effective security training creates actual value. It makes
an existing investment in technology more effective. It helps to make
information security staff more efficient and effective. It builds awareness,
and it reduces by measurable degrees the risks to business not only from
existing attack sources but also from suspicious events of any nature.
There are some basic principles
that will ensure this result:
Experienced teachers of adults
know that an audience of grown-ups responds to real examples and that
the examples must be put in the context of their own work and personal
lives. Adult learners
like to know about events that they can understand. As adults, they may
resist theory, and they are unlikely to accept authority without question;
but they do absorb quickly the lessons that have been learned the ‘hard
way,’ especially by others. Thus, for IT Security Awareness Training
to be effective, the teacher needs to use meaningful current events to
answer even basic questions like:
- Why must I have such a complex password?
- What should I do if a technician calls and asks for my password?
- How should I treat email attachments and why?
- What would the Bagle worm look like?
(In addition to newsworthy events, real-world, documented
examples, from such sources as the U.S. Secret Service and
CERT® Coordination Center in “Insider Threat Study: Illicit
Cyber
Activity in the Banking and Finance Sector,” August 2004 can be
useful in a security training curriculum.)

The key factor for success is getting
people to take collective, collegial ownership of security awareness.
In smaller companies, this can be facilitated in small classes, usually
of no more than 20 people, using engaging materials, including exercises,
that help participants buy in to policies and procedures. For larger companies,
the challenges are somewhat more complex, because the distance between
security administrators and staff seems to be greater. Employees of large
financial enterprises often complain about the “compliance people,”
who appear to be a cross between an alien civilization that has invaded
their business and a spying police force that is keeping them from pursuing
that business. Security awareness training should be differentiated from
other compliance
issues. While some compliance requirements may feel like impositions,
it is not difficult for personnel to grasp the need to repel intruders
and even to be vigilant about the threats from
internal tampering. Even in the largest organizations, training must ensure
that every responsible person has a real sense of his or her role. Bigger
companies often have a stronger ingrained, unwarranted faith in technology,
and the challenges of building the “people” aspect of security
awareness can consequently be greater. But they can be overcome.
In summary, training needs to emphasize
“awareness,” not just “security.” For adult learners,
mere “security” can seem to be something that is managed by
someone or something else. But “awareness” is a posture that
they can adopt – and that they like.
