Network-Access-Control

Network Security: Protecting the Edge and the Core Network security works at two speeds. The edge includes branch offices, remote workers, and field devices. The core handles data centers and cloud services where valuable data moves. A breach at either layer can threaten the entire system. By protecting both layers, you reduce risk and improve resilience. Edge risks are common. Weak device credentials, unprotected Wi‑Fi, insecure updates, and limited visibility invite trouble. Core risks are quieter but serious: misconfigurations, outdated patches, insider threats, and stolen credentials for privileged accounts can let attackers slip inside. ...

Network Security: Defending the Network Edge Edge security focuses on the points where users, devices, and data meet the network—the branch offices, remote workers, IoT sensors, and cloud services. Protecting these moments requires clear identity, strong policies, and continuous visibility. When defense sits near the edge, responses are faster and data remains safer even if a central system is slow or under stress. Key ideas for defending the edge Identity and access control: enforce MFA and least privilege, so only the right people reach the right resources. Microsegmentation: divide the network into small zones to limit movement of a breach. Encryption everywhere: TLS for data in transit, and strong encryption for stored data. Device posture and health checks: verify that devices meet security standards before granting access. Continuous monitoring: use network detection (NDR), log analysis, and alerting to spot unusual activity. Practical steps for teams ...
