CISC-RT-000080

Title
The Cisco router must not be configured to have any feature enabled that calls home to the vendor. (Cat II impact)
Discussion
Call home services will routinely send data such as configuration and diagnostic information to the vendor for routine or emergency analysis and troubleshooting. There is a risk that transmission of sensitive data sent to unauthorized persons could result in data loss or downtime due to an attack.
Check Content
Review the router configuration to determine if the call home service is enabled as shown in the example below: service call-home contact-email-addr [email protected] phone-number "+1-800-555-4567" customer-id "Customer1234" contract-id "Company1234" If the call home feature is configured to call home to the vendor, this is a finding.
Fix Text
Disable the call home feature as shown below: R5(config)#no service call-home
