The Role of Technology
What should be clear by now is that technology's role
in INFOSEC is really one of policy
enforcement.
Only with the clear articulation of INFOSEC policy can
intelligent decisions regarding specific technology be
made. Without such policy definition, questions like
whether something is ``secure enough'' cannot be
successfully answered, since each individual's notion
of what constitutes appropriate risk vs. benefit will
differ. This is a common problem in organizations
today, with the end result being large amounts of
money being spent in the name of security, with
remarkably little to show for the expenditure. At the
same time, the best intentions of technical staff are
frequently overrun by a manager's arbitrary decision
about how much risk the organization is willing to
accept. So while the technologists and management
spend their time frustrating each other, the
information critical to the organization's operation
continues to be at risk.
Technology, through its design and configuration, will
express policy. Though inappropriate for
non-technical managers to decide whether particular
protocols may be allowed between their sensitive
networks and untrusted networks, such non-technical
managers must provide the higher-level framework
defining operational and risk management requirements.
Technical people, understanding this framework, will
be able to implement the organization's policy
successfully.
No amount of spending will secure an organization
whose policy is fundamentally flawed. No amount of
policy will secure an organization where the policy is
not effectively implemented. Cookies and milk are
better separated than policy and technology.
Thus, INFOSEC can be described as “saying what
you do, and doing what you say.” Following this
simple maxim is really the goal of information
security. INFOSEC, however, is not an end to itself.
Rather, it is part of a larger framework of how
information is to be collected and managed--the
processes that define a business operation.
