| Term | Definition |
|---|---|
| DomainKeys Identified Mail (DKIM) | An email authentication method designed to detect email spoofing by providing a mechanism to allow domain owners to assert that a given email message is authorized by the company responsible for that domain. When DKIM is employed, messages are signed with a cryptographic signature allows the receiver to check that an email claimed to come from a specific domain is indeed authorized by the owner of that domain. |
| Email Authentication | A process that confirms that an email message purporting to be from a given domain name was not forged and that it truly originated from the company or organization responsible for that domain. This process allows an ISP to identify suspected forgeries, reject known forgeries, and may assist when attempting to block known spamming domains. ISPs can also allowlist email from reputable domains and bypass certain types of filtering to minimize false positives. |
| Internet Protocol (IP) Address | A number that identifies a computer on the Internet. An IP address consists of four numbers (0-255) separated by periods. An ISP can use an email server's IP address when determining whether to accept the email. Sharing an email server uses a "shared" IP address; using your own IP address uses a "private" or "dedicated" IP address. |
| Phishing | Attempting to criminally and fraudulently acquire sensitive information, such as usernames, passwords, and credit card details, by masquerading as a trustworthy entity in an electronic communication. eBay, PayPal and online banks are common targets. Phishing is typically via email or instant messaging and directs users to enter details at a website. |
| Sender Policy Framework (SPF) | A DNS-based email authentication technology that allows senders to publish a list of IP addresses to tell ISPs that a mail message referencing a given domain is legitimate if it did indeed originate from an IP address found in the domain’s published SPF record. |
| Spoofing | Falsifying information in an email message, for example, using a fake from address. |
