Final answer:
To counter email spoofing, organizations can train staff members to identify phishing attempts, use email authentication protocols like SPF, DKIM, and DMARC, and encourage careful proofreading and proper email etiquette.
Step-by-step explanation:
An organization can counter email "spoofing" by implementing several practices to ensure email security and educate its members. Staff members should become critical readers of every email, a skill that can be enhanced through regular training exercises such as receiving fake phishing emails. This technique is employed by some universities IT departments as a means of practical education.
Experts recommend implementing protocols such as Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting & Conformance (DMARC) to authenticate outgoing messages and ensure they have not been tampered with during transit. Additionally, it is crucial for individuals to proofread emails and ensure they are grammatically correct and well-composed, as careless mistakes can often be a sign of phishing attempts. Using proper email etiquette, such as correct spelling, proper grammar, and professional formatting with bullet points or numbered lists, can help maintain clarity and professionalism in communication.
