Information Security is a complex
problem in many ways: complex networks, complex requirements, and complex
technology. But it would be much more manageable if it were static. However, it
is far from static. New systems are added to the network. Business requirements
change frequently. And the threat landscape is extremely dynamic. Managing
security in this environment is a significant challenge.
A key to successful security
management and in turn effective security is understanding the current state of
your security posture. Complexity inherently introduces mistakes, gaps and
obscures them at the same time. For example, a firewall, implemented with the
specific purpose of limiting risk by controlling access, often has
configurations so complicated that it is impossible to understand what access
is being allowed. And if it is impossible to understand what access is being
allowed, it is impossible to understand the risk it is limiting or exposing. Helping
analyze these complex configurations and provide visibility into what access is
being allowed or denied has been a key value of Security Manager for over a
decade.
But it takes more than occasional
analysis to ensure effective security. With the near-constant changes happening
in the network and the dynamic threat landscape, continuous assessment is
required. Establishing controls, definitions of correct or incorrect
configuration or behavior, and continually evaluating the security of the
network against those controls is the most effective way to automate this
analysis. What you do with this analysis is what separates truly effective
security organizations from the rest.
Improving security requires more than
just fixing what is broke. It requires measuring the effectiveness of security
operations; technology, people and processes. Continually assessing the
security controls defined and measuring the results over time creates a
framework to measure security operations. Setting the expectation that improvement
is the goal will result in improved security.
