Adaptive Access Control and Threat Mitigation in SDN-Based DataCenters for BYOD Environments

In today’s corporate environments, the widespread adoption of Bring Your Own Device (BYOD) policies has significantly enhanced employee mobility and productivity. However, this trend also introduces critical security challenges, particularly within Software-Defined Networking (SDN)-based data centers, where traditional security measures often fall short in addressing the complexities of personal device integration. This paper presents a novel security framework designed to dynamically manage access control and mitigate threats in SDN-based data centers tailored for BYOD environments. The proposed framework introduces the Adaptive Access Control and Threat Mitigation Algorithm (AACTMA), which leverages SDN’s centralized control capabilities to enforce real-time, context-aware access policies. AACTMA continuously analyzes user and device behavior through advanced machine learning techniques, establishing a baseline of normal activity to detect and respond to anomalies. In the event of a detected threat, the framework dynamically reconfigures network policies to isolate compromised segments, thereby mitigating potential risks. Additionally, AACTMA integrates robust encryption protocols to secure data both in transit and at rest, while multi-factor authentication (MFA) and device fingerprinting ensure that only trusted devices and users gain access to sensitive resources. Extensive simulations and real-world scenario testing demonstrate that the proposed framework significantly enhances security in BYOD-enabled SDN data centers, offering superior protection against advanced and evolving cyber threats. This research provides a comprehensive solution to the pressing security challenges posed by BYOD policies, paving the way for more secure and efficient SDN-based data center operations.
