Surveying Access Control Systems
by Jeffrey Dingle
May 1, 2008
At some point in a security operation, an assessment needs to be made of
your access control needs.
Unfortunately, this review generally occurs after an event (“event” is a
polite word for “problem”). While
post-event review is important, it’s also important to review the operations on
a periodic or regular basis. Generally
speaking, a review of your system will occur for one of three reasons: after an event, on a regular, periodic basis,
and whenever a significant change in operations or property occurs.
This column will address WHAT to look for
when reviewing your access system. The
questions are geared toward a building.
Each building is addressed separately, with multiple buildings
comprising a facility. These basic
questions will provide a good overview of your operation.
The first two questions address policy and procedure.
How is employee access to their building controlled during normal
business hours? Is it keys? Access cards? ID badges? Security officers? Is it a combination of everything, or is the
access open, with no controls?
The same questions go for access after normal
business hours - Is it keys? Access
cards? ID badges? Security
officers? Is there a combination of
everything, or is the access open, with no controls?
Reality Vs. Perception
An important issue here is to see if there is a difference in what
is supposed to be done as opposed to what is actually being done. I was recently at a facility in which the
access policy was excellent, especially for after-hours access. The only issue was that the policies simply
were not followed. Policy required that
loading dock doors be secured unless the dock bay was “active” - a good policy.
Reality was that the doors were often left open to allow for
ventilation. Even the best policy is
useless if it isn’t followed.
The threat level of the facility will help
to determine the methods used to provide access control. Keys are a basic access tool, but are easily
lost, stolen and compromised. Access
cards and/or ID badges are more secure, but are also more costly and difficult
to operate. The threat (or lack of
threat) may dictate that no access system is necessary at all. Match the system to the need.
The next questions address the access control system.
The most basic question is: Is there an access control system in
place? Tied to that question is: Do you
really need an access control system?
Understanding your true access needs is important to meeting
them. If there is an existing access
control system, does it support different access levels and does it support
time zones? Dividing access into
different levels greatly increases security by restricting access to only areas
where access is required.
In other words, all employees can gain access to the building, but
only those who need access to the 22nd floor get access to the 22nd floor. Time zones restrict access to specific times
of the day. Time zones can be very
general, but still very effective -- for example, students in a school are
allowed access from 7am to 4pm, while employees (teachers, staff) have 24-hour
access. The night cleaning crew only has
access from 4pm to midnight. Time zones
keep people from wandering around a facility when they have no business there.
ID Card, Badge Concerns
Identification badges will always be an issue.
Are badges issued to all employees? Is the wearing of badges required, and even
more importantly, is the requirement enforced?
The wearing of badges can be a difficult issue. There is a tendency in upper management to
feel that they are “too important” to need to wear a badge. This is a dangerous precedent. No one is too important to wear a badge. In
fact, the best security management practice is to have everyone, especially the
security staff, to “lead by example” and wear badges. Badges cannot be a partial program; either
badges are required for everyone or the program is not effective. Management buy in is essential to making a
badge program successful.
If badges are required, what is the process to allow access to
someone who has forgotten a badge, and what is the process for someone who has
lost their badge? Some facilities will
not allow temporary badges to be issued.
If a badge is required, you must have your badge to gain access. If you forget your badge, you go home and get
it.
While this is not a “customer friendly” policy –
people generally only forget their badge once.
The issuance of temporary badges brings with it the chance of a security
issue. Essential to the issuance of
security badges is a strong policy commitment to timelines.
Where Is It?
The loss of a badge is a problem.
Recently an airport advised me that a $200 fee is required to replace a
badge. This is both good and bad. The
extreme fee causes people to take care of the badge, and they are less likely
to lose it, yet the extreme fee also makes people hesitant to report a lost
badge.
Take a critical look at your access system and
practices. Ask these quick questions on
a regular basis to see if your access procedures are effective.
