Background for this topic.

Firewalls are security controls that permit or block network connections according to policy. They can operate at network boundaries, between internal segments, on individual hosts, or in cloud environments. Basic rules use addresses, ports, protocols, and connection state; more advanced firewalls may inspect applications or encrypted traffic where configured. Their purpose is to limit which systems can communicate, not to determine that all permitted traffic is safe.

Security depends heavily on accurate policy and maintenance. Overly broad, obsolete, or conflicting rules can expose services or allow unnecessary lateral movement, while unmanaged administrative interfaces and unpatched firewall software create additional attack surfaces. Practitioners should restrict management access, apply least-privilege rules, review and remove exceptions, and monitor logs for unexpected connections and policy changes. Firewall logs can support investigation, but encryption, evasion, and traffic allowed by policy may limit what the control can detect.

Why native cloud security falls short

Your cloud security must stand alone Partner Content As cloud adoption accelerates, many organizations are increasingly relying on the native security features offered by cloud service providers (CSPs). The ability to manage web application firewalls (WAF), data encryption, and key management (KMS) within a single provider ecosystem appears efficient and convenient. However, when security and reliability are viewed through the lens of enterprise risk management, this convenience may come at a significant cost.…
