What specific weakness does direct internet access in SD-WAN create?

Direct internet access in SD-WAN can introduce a specific weakness against advanced threats primarily because it opens a direct pathway for internet traffic, which can lead to exposure to various cyber threats. Unlike traditional dedicated circuits, where all traffic is funneled through a centralized point of control, direct internet access allows users to bypass traditional security measures. This means that sensitive data could be at higher risk of interception, malware insertion, or other attacks from the vast array of threats present on the open internet.

Advanced threats often employ sophisticated techniques, including phishing, advanced persistent threats (APTs), and zero-day exploits, to circumvent defenses. When organizations implement SD-WAN with direct internet access, they must ensure robust security measures are in place, such as web filtering, intrusion detection and prevention systems, and endpoint protection. Otherwise, they leave themselves vulnerable to threats that can exploit weak links in their security posture due to the more open nature of direct internet access.

In summary, the inherent nature of direct internet access weakens defenses against advanced threats by increasing exposure to malicious activities and encouraging a need for rigorous layered security controls to mitigate the risks associated with such direct connections.
