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 switch configuration to determine if the call home service is enabled as shown in the example below:

callhome
 contract-id CompanyXYZ
 customer-id CompanyXYZ
 email-contact netadmin@CompanyXYZ.com
 phone-contact +1-800-555-4567
 enable

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:

SW1(config)# callhome
SW1(config-callhome)# no enable 
SW1(config-callhome)# end
