Fortinet IAM uses the following resources to provide these protections: Public key infrastructure (PKI) refers to tools used to create and manage public keys for encryption, which is a common method of securing data transfers on the internet. One of the benefits of the web of trust, such as in PGP, is that it can interoperate with a PKI CA fully trusted by all parties in a domain (such as an internal CA in a company) that is willing to guarantee certificates, as a trusted introducer. It also includes official attestation from a source that both entities trust. - Permission Assignment (PA) many-to-many relationship. Generally speaking, regardless of the specific use case, PKI provides a more secure form of communication in a world that relies on the digital transfer of information. Certificates are stored within a certificate database. Otherwise, people can both initiate and intercept emails at will, pretending it is from a device it is not or even grabbing and then changing the content of emails in a kind of MITM attack.
