Ways to Prevent Spoofing There are several ways to prevent spoofing attacks from happening in your organization, including: Sender Policy Framework (SPF) SPF is a method of combating email spoofing. It’s used to verify whether or not an email sender is authorized to send messages on behalf of a domain. If it’s not, the receiving server can reject the message immediately. The SPF record contains a list of IP addresses authorized to send mail for a domain. The record is placed in the DNS zone file for each domain.
You can use the free SPF checker tool by PowerDMARC. DomainKeys Job Function Email List Identified Mail (DKIM) DKIM verifies that an email is legitimate and hasn’t been tampered with during transmission. It does this using digital signatures added to the message during transit, which the receiving server’s DNS records can verify. Domain-Based Message Authentication, Reporting Conformance (DMARC) DMARC policies for how your organization handles fraudulent emails that claim to be from your company but aren’t coming from your organization’s servers.
These policies include things like setting up complaint-handling procedures and instructions for how you want ISPs should handle suspected spoofed emails from your domain. Ways to Prevent Phishing Phishing attacks can be very convincing. They often come from official-looking email addresses, contain familiar logos and images, and even sound like the real thing. To avoid falling for these tactics: Don’t open attachments or click on links in emails if you don’t know who sent them.
