The best strategy for choosing security tools and architecting networks is to focus on staffing and resources, risk tolerance, and business change.
While security professionals like to think that a “network is a network,” in truth, every network is bespoke – formed from accepted design patterns, business requirements, organic growth and designer preference. Consequently, it’s not feasible to choose security tools with the mindset of, “If I just had this network intrusion detection system (NIDS) and that user behavior analytics (UBA) tool, then I’d be secure for sure.”
