Network Access Control (NAC)

In today’s modern workplace, organizations face significant challenges in managing access to increasingly complex networks. With the growing number of IoT devices, remote employees, and external vendors connecting to corporate networks, the risk of cyberattacks and unauthorized access continues to rise.

 

📌 Network Access Control (NAC) is a technology designed to control, authenticate, and secure device access to corporate networks. It ensures that only verified and policy-compliant devices are allowed to connect, enhancing overall network security.

Without NAC, companies face the following risks:

Uncontrolled Access → Unknown Devices Entering the Network Without Clear Authentication

Devices without proper authentication can access the network, posing a security risk.
Network-Based Attacks → Malware and Ransomware Spread Through Unprotected Devices

Malware and ransomware can propagate across the network through devices lacking adequate protection.
Lack of Visibility & Compliance → No Granular Control Over Devices Accessing the Network

Without detailed control over devices accessing the network, visibility is compromised, increasing risk.
Threats from IoT & BYOD (Bring Your Own Device) → Unmanaged Personal Devices as Attack Entry Points

Personal devices that are not managed can become potential entry points for attacks on the network.

How It Works
How Network Access Control (NAC) and Security Awareness Training Protect Against Unauthorized Access:
Show Details
a. Connected Devices Verification
    NAC verifies device type, user identity, and risk level before granting access.
b. Policy-Based Access Enforcement
    NAC determines if a device receives full, limited, or denied access based on policies.
c. Monitoring & Threat Detection
    NAC continuously monitors network activity to detect anomalies or policy violations.
d. Automated Response & Isolation
    If a threat is detected, NAC can automatically block or isolate high-risk devices.
e. Audit & Compliance Reporting
    All activities are logged for investigation and security audit purposes.
