Recent major data breaches at Equifax and Deloitte are reminders of the dangers of failing to practice cybersecurity fundamentals.

Technical solutions can help, with the right support and funding, but asset management is a process and a discipline, not just a tool.

    Knowing the organization's assets and their value will inform what gets monitored and how. Security monitoring solutions are improving, with richer analytics and machine-learning capabilities as well as more expansive integration. Organizations should monitor their environments around the clock. For small and mid-size organizations that lack in-house resources for such monitoring, partnering with a trusted third party or managed security service provider is an option.

    Another fundamental aspect of improving visibility and monitoring is to proactively look fot existing weaknesses or vulnetabilities and...
