a VLAN is a core network security concept that every cybersecurity and GRC professional should understand.
What Is a VLAN?
a VLAN refers to the practices, processes, or technologies related to a vlan within the context of information security and risk management. Understanding a vlan helps organizations protect their systems, data, and operations from relevant threats.
How It Works
a VLAN is applied through a combination of policies, technical controls, and organizational procedures. Security teams implement a vlan as part of a broader security program aligned to industry frameworks and regulatory requirements.
Why It Matters
Organizations that correctly implement a vlan reduce their exposure to cyber risk, improve regulatory compliance, and strengthen their overall security posture.
