Understanding Phishing and Spam Threats
Phishing and spam are big cyber threats that can harm email security. They expose people and businesses to dangerous activities4. Phishing uses emails, texts, and social media to trick people into sharing personal info4. Scammers try to make you act fast, saying you’ll get rewards or face penalties if you don’t4.
What Is Phishing?
Phishing is a trick where scammers send fake messages to get your private info or make you do something risky4. Watch out for emails with mistakes in spelling or grammar. Real companies usually don’t make those errors4. If an email says “Dear sir or madam,” it might be a scam4.
Common Phishing Techniques
Phishers might send emails with wrong domain names or small spelling mistakes4. Don’t click on links or open attachments from shady emails4. Check if the email is real by contacting the company directly4. Tell others about suspicious emails to help fight phishing4.
If phishing leads to financial loss or identity theft, report it to the police4. Change your passwords and use extra security steps to protect your accounts4.

Implementing DMARC and SPF Records
In today’s digital world, keeping your email safe is key. Two important tools to help are DMARC (Domain-based Message Authentication, Reporting, and Conformance) and SPF (Sender Policy Framework)21. They work together to stop email spoofing, a trick used by hackers in phishing and other attacks22.
Understanding DMARC
DMARC lets you control how your emails are handled. It uses DKIM and SPF to check if emails are real. This way, you can stop fake emails that claim to be from your domain21. With DMARC, you can tell your system to reject, quarantine, or accept emails that don’t pass checks, keeping your emails safe22.
Sender Policy Framework (SPF)
SPF helps DMARC by saying which servers can send emails for your domain. It makes a DNS TXT record with the allowed IP addresses. This helps check if emails are real, making it harder for hackers to fake them21. But, make sure your SPF record doesn’t have more than 10 DNS lookups, or it might not work right23.
Using DMARC and SPF is a big step in protecting your emails from phishing and other threats. These tools help make sure your emails get through, keep your brand safe, and prevent damage from email scams2122.
| DMARC | SPF |
|---|---|
