Method to automate the renewal of digital certificates
View Patent ↗The disclosure relates to the management of PKI digital certificates, including certificate discovery, installation, verification and replacement for endpoints over an insecure network. A database of certificates may be maintained through discovery, replacement and other activities. Certificate discovery identifies certificates and associated information including network locations, methods of access, applications of use and non-use, and may produce logs and reports. Automated requests to certificate authorities for new certificates, renewals or certificate signing requests may precede the installation of issued certificates to servers using installation scripts directed to a particular application or product, which may provide notification or require approval or intervention. An administrator may be notified of expiring certificates, using a database or scanning or server agents. Interaction with certificate authorities may be by an abstractor providing a common intefface for issuing signing requests to disparate certificate authorities. Digital certificate management may also be applied to network-connecting client devices.
1. A method for automatically renewing digital certificates in a managed network using a certificate authority abstractor, said method comprising the steps of:
receiving notifications regarding a managed digital certificate;
identifying a managed server corresponding to a digital certificate referred to in a received notification from a certificate authority;
communicating with the managed server, the communicating causing the managed server to generate a certificate signing request and return the request to the managing device;
communicating with the managed server, the communicating causing the managed server to generate a certificate signing request and return the request to the managing device;
receiving the selection of a certificate authority;
transmitting a generated and received certificate signing request to a certificate authority, said transmitting being accomplished through the execution of a script corresponding to the selected certificate authority, the script being one of a set of scripts;
receiving a certificate signed by a certificate authority generated from a certificate signing request;
identifying a destination managed server corresponding to a received certificate signed by a certificate authority;
installing a received certificate signed by a certificate authority to an identified destination managed server; and
configuring an identified destination managed server to use a private key corresponding to an installed certificate.
2. A method according to claim 1 further comprising the steps of:
generating a new asymmetric key pair,
and installing a generated private key of a new asymmetric key pair to an identified destination managed server; and wherein a generated certificate signing request includes a generated public key of a new asymmetric key pair.
3. A method according to claim 1 , further comprising the step of installing a received certificate signed by a certificate authority by a network interface provided by a web interface of a web server installed to an identified destination managed server.

5. A method according to claim 1 , further comprising the step of installing a received certificate signed by a certificate authority by an agent program installed to an identified destination managed server.
6. A method according to claim 1 , further comprising the step of restarting a destination server program.
7. A method according to claim 1 , further comprising the step of restarting a destination server computer.
8. A method according to claim 1 , further comprising the step of notifying an administrator to restart a destination server program or destination server computer.
9. A method according to claim 1 , further comprising the step of confirming the installation of a received certificate to a destination server following the performance of a set of installation steps.
10. A method according to claim 9 , further comprising the step of generating an alert to an administrator if the installation of a received certificate to a destination server is not confirmed.
11. A method according to claim 1 , further comprising the steps of:
informing an administrator of a certificate for which a notification has been received from a certificate authority;
prior to said transmitting, requesting approval to renew a certificate for which a notification has been received from a certificate authority; and
receiving, in response to a request for approval, an indication from an administrator that a certificate is to be renewed.
12. A method according to claim 1 , further comprising the steps of:
following said receiving a certificate signed by a certificate authority, informing an administrator of that renewed certificate;
prior to said installing, requesting approval to install a renewed certificate received from a certificate authority; and
receiving, in response to a request for approval, an indication from an administrator that a renewed certificate is to be installed.
13. A method according to claim 1 , further comprising the step of storing a received certificate signed by a certificate authority to a backup storage device.
14. A method for automatically renewing digital certificates in a managed network using a certificate authority abstractor, said method comprising the steps of:
receiving notifications from a certificate authority regarding a managed digital certificate;
identifying a managed server corresponding to a digital certificate referred to in a received notification from a certificate authority;
communicating with the managed server, the communicating causing the managed server to generate a certificate signing request and return the request to the managing device;
receiving the selection of a certificate authority;
transmitting a generated and received certificate signing request to a certificate authority, said transmitting being accomplished through the execution of a script corresponding to the selected certificate authority, the script being one of a set of scripts;
receiving a certificate signed by a certificate authority generated from a certificate signing request;
identifying a destination managed server corresponding to a received certificate signed by a certificate authority;
installing a received certificate signed by a certificate authority to an identified destination managed server;
configuring an identified destination managed server to use a private key corresponding to an installed certificate; and
performing a restart action selected from the group of commanding an identified destination managed server to perform a restart, commanding an identified destination managed server to restart and notifying an administrator to restart a destination server program or destination server computer.
15. A method according to claim 14 , further comprising the steps of:
generating a new asymmetric key pair; and
installing a generated private key of a new asymmetric key pair to an identified destination managed server.
16. A method according to claim 14 , further comprising the step of installing a received certificate signed by a certificate authority by a network interface provided by a web interface of a web server installed to an identified destination managed server.
17. A method according to claim 14 , further comprising the step of installing a received certificate signed by a certificate authority by a shell interface to an identified destination managed server.
18. A method according to claim 14 , further comprising the step of installing a received certificate signed by a certificate authority by an agent program installed to an identified destination managed server.
19. A method according to claim 14 , further comprising the step of confirming the installation of a received certificate to a destination server following the performance of a set of installation steps.
20. A method according to claim 19 , further comprising the step of generating an alert to an administrator if the installation of a received certificate to a destination server is not confirmed.
