Industry Insight: Developing a United Front
Physical and IT security strategies
have functioned independently of each other for a long time, but pressure to
unify them is mounting. While both security strategies are critical to the
overall safety of a business, the gap generated between the two security disciplines
makes enterprises vulnerable to attack. Anxious to fill the breach, managers
and organizational leaders are working to correct this problem and they are
looking to the security industry for a remedy that makes sense.
The importance of bridging the physical and IT security chasm presents the
security industry with an opportunity to learn and adopt integrated practices
that will grow business and add value to their customer base. Manufacturers,
consultants and integrators must address today's need for convergence if they
expect to compete in tomorrow's broader security industry.
How Does Access Control Fit In?
The convergence initiative to date has focused on using a single credential
for authentication to the physical and network security systems. A token
issued with the security credentials for the access control system to validate
building entry can double as the IT credential. A token certificate supplies
the authentication data that the IT security systems use for the network.
The best vendors and integrators will enable organizations to adopt this dual
approach to authentication technology while building on the investments already
made in the physical security infrastructure. As a result, organizations can:
- Adopt convenient and secure dual-purpose credentials to access facilities
and IT systems.
- Maximize security by ending casual access to sensitive locations and resources.
- Enable legacy IT applications to accept a new authentication method.
- Reduce help desk costs and work hours lost resulting from missing or forgotten
passwords.
The single-credential approach can be time- and cost-effective within the
IT area of an organization. It can eliminate the need for employees with redundant
jobs, such as maintaining the same data for different applications. Moreover,
it can physically authenticate access to network applications and increase
an organization's ability to monitor employee activity. Businesses will have
the ability to tie operational processes to security by using the same credential
for application and network authentication.
Another advantage of the single credentialing system is the physical validation
of the end user for IT security purposes. In the physical security world, there
is a security staff member on hand to issue that first credential and validate
that the employee is real and present. With IT credentials, often created by
other programs, users may not always be "real." The obvious problem is that
there is no one to validate whether the issued credential is being given to
an authorized user. Requiring credentials to be issued physically rather than
virtually strengthens network security and provides the IT community with a
simple solution to one of its chief security issues.
Provisioning: Who's in Charge?
Provisioning is the practice of automatically issuing a user all the credentials,
rights and roles on all or many of the company's servers and systems. Managing
this process is one of the biggest challenges organizations face. Product
vendors and dealers familiar with this architecture can add a great deal
of value to a business when helping validate these credentials.
Typically, provisioning begins with the HR server or employee database. An
effective process enables bi-directional communications between the HR system
and the security system. When a new employee is created in the system, the
credential information passes from one system to the other. The privileges
and roles of these credentials can have a significant impact on a business'
security. Having a security staff member at the end of the process to validate
the cardholder as a real and authorized person is much more powerful than any
electronic process with no human intervention. Yet this kind of collaboration
between IT, physical security and HR can cause conflict within the organization.
Physical security personnel have a duty as a part of the overall security
force to know the IT technologies that extend beyond their standard systems.
Expanding their understanding steps up the level of security throughout the
enterprise and is one of the strongest reasons for integrating physical and
IT security.
Enterprise Security Management
Security event management platforms pose another issue that concerns many enterprise
customers. Many access control systems offer the ability to construct events
from multiple vantage points in the security infrastructure. Monitoring intrusion
and fire events, video, asset activity, paging and phone systems are all
part and parcel of a state-of-the-art security system. Simply having such
a platform at this time is an achievement. And still, the market often wants
more.
A similar paradigm exists in the IT world. A security management system for
IT gathers information from firewalls, anti-virus and intrusion detection applications,
and a variety of non-security-related hardware and software on the network.
This infrastructure is fast-moving and has many data points, as does the physical
security infrastructure. However, the volume of event data that needs to be
managed on the IT side is exponentially larger. Thousands of invalid access
attempts for a single program can occur in nanoseconds.
Because of this volume, the IT industry has created tools such as IBM's Tivoli,
Hewlett Packard's OpenView and Computer Associate's eTrust Security Command
Center. These tools serve both management and security purposes and, as such,
are key to integrating physical and IT security. Integration tends to hit a
snag, however, when event data is transferred from physical security into the
IT security management system. The answer is to normalize and create a common
protocol for this event data to be shared among all security systems.
Wanted: Commitment to Interoperability
Sooner, rather than later, decision-making executives will adopt a policy of
convergence as they continue to face the following trials and pain points:
- Inability to centrally manage physical access control systems from different
vendors
- Incompatibilities between building access hardware tokens and IT access
tokens
- Inability during forensic investigation to relate building access logs
to IT logs
- Limited situational awareness because no monitoring system can provide
a coordinated view of physical and IT attacks
- Inability to apply business logic to security event data when it comes
from multiple sources (physical and IT)
- Inability to fully coordinate cardholder lifecycle management for cardholders
across multiple credentialing systems
As enterprise security executives continue to see these problems, they will
seek solutions and services provided by integrators and technology providers
who are committed to interoperability. There will quickly be a dramatic shift
to the vendors and integrators whose solutions promote organizational and technical
integration between the physical and IT worlds in order to maximize security
while cutting operating costs. Solutions that meet these needs will improve
security for businesses, but also will enhance the security of our nation and
our world.
Customers will seek systems integrators offering technologies that convey
an integrated security approach. The established manufacturers, consultants
and integrators who have demonstrated proven product reliability and first-class
customer service over the years will be the first choice. The security industry
at all levels must develop products and adopt practices that promote an integrated
approach to security in order fill immediate customer needs.
Looking Forward
We've witnessed the inauguration of several groups dedicated to standardizing
processes and applications and thereby ensuring the products, policies and
procedures needed for complete and successful security are available to any
company, vendor or customer who requires them. One such group, the Open Security
Exchange, has formed a consortium of companies and is developing a generic
set of standards to alleviate the burdens of the two security disciplines.
In the next few months, the OSE will publish documents to raise awareness
about the needs of the physical and IT security industries. While not the final
answer to those needs, these documents will help create better security offerings
and fill the gaps left by current practice. New members have joined the OSE
over the past few months, and many more are expected, establishing an organization
governed by the needs of those who use and rely on security technology, as
well as those who provide it.
