Why is communication and network security vital in hybrid cloud environments?
TL;DR: Communication and network security is essential for securing data in transit, especially in hybrid cloud environments where internal and external networks intersect and expand the threat surface.
The 6clicks expert guide Mastering the Cybersecurity Domain in 2025 identifies communication and network security as a key domain for protecting information as it moves between users, systems, and environments. This is especially critical in today’s hybrid and multi-cloud architectures, where sensitive data constantly flows across distributed infrastructure.
This domain includes designing secure networks, encrypting communication channels, and monitoring traffic for anomalies—measures that are critical for both performance and protection.
Key practices in network and communication security:
-
Secure network architecture
Segment networks, implement firewalls, and apply defense-in-depth strategies. -
Encryption protocols
Use technologies like TLS, IPsec, and VPNs to protect data in transit. -
Zero trust principles
Assume breach, verify continuously, and limit lateral movement between systems. -
Secure remote access
Control VPN and remote desktop entry points with MFA and session logging. -
Traffic monitoring and alerting
Implement intrusion detection/prevention systems (IDS/IPS) and network behavior analytics.
Why it matters in 2025
With growing adoption of SaaS, remote work, and edge computing, organizations are no longer protected by a fixed perimeter. Data flows dynamically across devices, cloud providers, and global endpoints.
Communication and network security ensures:
-
Confidentiality and integrity of data in motion
-
Protection against eavesdropping, MITM attacks, and unauthorized access
-
Compliance with regulatory requirements for encrypted transmission
