Network access controls are beneficial not just because they provide security for business networks but also because they provide clear methods of tracking user access to sensitive data and applications. With NAC tools, a business is better prepared to identify the root cause of an attack on its most sensitive database if it knows the database was protected by authentication controls and can identify which users had access to it. Consistently implemented network access controls foster better transparency and accountability company-wide.
Enterprises should implement NAC technology to protect their proprietary information and customer data, as well as to maintain standard business operations. For example, if an attacker breaches a network because the router’s access credentials had a default admin password instead of a strong password, the attacker could not only steal business data but also bring down a key customer-facing application. This could cost the business millions of dollars and endanger its data.
