An effective defense relies on the three pillars of IT security: protection, detection, and reaction. This multi-faceted approach ensures you're able to protect your information, assets, and users; detect incoming threats; and react to threats in a well-organized, structured, and sophisticated manner. It's important to remember that a single pillar isn't enough to secure your organization. Gone are the days of deploying a security solution-however effective it may be-and sitting back while it stops threats before they get inside your environment. If your organization ignores the detection and reaction stages of modern security, you've left yourself wide open to attack. Constant vigilance is the new standard.
