![]() With self-signed certificates nobody, except the other end of your communication, knows who you are and therefore they do not trust you as an authority. ![]() While these certificates are universally accepted, it is cumbersome and expensive to have all certificates on a corporate network signed with this level of trust. For example if VeriSign signs your CA root certificate, it is trusted by everyone. The trust in a certificate comes from the authority that signs it. CRLs are maintained by the CA that issues the certificates and includes the date and time when the next CRL will be issued as well as a sequence number to help ensure you have the most current version of the CRL. If your certificate is on this list, it will not be accepted. This list includes certificates that have expired, been stolen, or otherwise compromised. Using the local certificate example, a CA root certificate would be issued for all o f instead of just the smaller single web page.Ĭertificate revocation list (CRL) is a list of certificates that have been revoked and are no longer usable. You can select I m po r t to install a certificate from the management PC.ĬA root certificates are similar to local certificates, however they apply to a broader range of addresses or to whole company they are one step higher up in the organizational chain. Installed Remote (OCSP) certificates are displayed in the Remote Certificates list. For dynamic certificate revocation, you need to use an Online Certificate Status Protocol (OCSP) server. Remote certificates are public certificates without a private key. For information about installing a local certificate, see Obtaining and installing a signed server certificate from an external CA on page 529 These can optionally be just the certificate file, or also include a private key file and PEM passphrase for added security.įor information about generating a certificate request, see Generating a certificate signing request on page 526. For example a personal web site for John Smith a t (such as ) would have its own local certificate. Generally they are very specific, and often for an internal enterprise network. Local certificates are issued for a specific server, or web site. FortiOS supports local, remote, CA, and CRL certificates. There are different types of certificates available that vary depending on their intended use. Ĭ e r t i f i ca t e types on the FortiGate unit ![]() See Authenticating IPsec VPN users with security certificates on page 535. The VPN gateway configuration can require certificate authentication before it permits an IPsec tunnel to be established. Unlike administrators or SSL VPN users, IPsec peers use HTTP to connect to the VPN gateway configured on the FortiGate unit. Certificate authentication is a more secure alternative to preshared key (shared secret) authentication for IPsec VPN peers.
