Final answer:
To quarantine a device in the access layer like FortiSwitch or FortiAP, Security Profiles in Fortinet's solutions are used. They enable the enforcement of policies and protect networks by isolating compromised devices.
Step-by-step explanation:
To quarantine a device in the access layer, such as a FortiSwitch or FortiAP, you would use Security Profiles. These profiles are part of the security configuration in Fortinet's solutions which allow administrators to enforce policies and protect the network from vulnerabilities and threats.
Security Profiles are applied to FortiGate interfaces or zones and can include a range of security measures such as antivirus, web filtering, and intrusion prevention. When a device is identified as compromised or violating configured policies, Security Profiles can automatically or manually quarantine the device, preventing it from communicating with the network until the issue is resolved.
This quarantining of devices helps in maintaining the integrity of the network and reducing the risk of spread of any infection or vulnerability within the network.
