In the whole country and industry, a technology has shared countless secrets for more than 20 years. Yes, despite the emergence of social media, messaging applications and project management tools, e-mail is actually still the best online communication channel, but it is also an object of concern in terms of security. Given the age of technology and the incentives for hackers to try fraud, it’s easy to see why businesses and individuals have been troubled. Due to the emergence of multifactor authentication, cloud storage, digital ecosystem and social login, many people have to rely on the security of e-mail addresses to support the day, which is more worrying than ever before.
Sadly, e-mail can be attacked by other methods that deal with pushing, forgery and manipulation of all types of people, so it’s not enough to use complex passwords for protection. Among them, e-mail security framework becomes very important. This makes it easier to be sure of your email’s legitimacy. But why does fraud pose such a threat? What are these frameworks and how do they help website owners do it safely? Can you really rely on them to protect you? Take a look. E-mail fraud is such a headache because we are moving to cashless payment, online banking and telecommuting, requiring more and more extensive and in-depth digital communication (often sensitive topics). The more we trust email, the more email hackers will attract. If it comes to people who don’t know enough about technology, they can know when email is cheated.
If someone only knows how to use email, but doesn’t even know the fact that they can dump email, they will undoubtedly receive fraudulent email. Moreover, the income of swindlers is much greater than expected by telephone fraud. This is because you can automate fraudulent email and avoid long phone conversations, exposing loopholes in the cover story. E-mail fraud is a concern for legitimate domains because it doesn’t look good. Even if people eventually know that you are not responsible, they will still associate your brand with fraud to some extent. Therefore, if you want to trust the domain and prevent people from trying to use the domain maliciously in your name, you must protect your email. The method is as follows:
Introduce the most common e-mail security framework. The two most commonly used e-mail frameworks are SPF (Sender Policy Framework) and dkim (domainkey identified mail). Their functions are similar but slightly different. SPF needs a supported host name or IP address, and dkim needs a correctly encrypted header message. More detailed description: after SPF is enabled in the SPF working mode website domain, the host name and IP address list that will be regarded as the legal e-mail source of the domain and the list added to the website DNS record (add your URL to your IP address).
All e-mail systems that appear to receive e-mail from this domain address will compare the IP address used to send e-mail with the list of DNS records. If there is a match, the email will be considered legal. If it doesn’t match, the system will find that the email is deceptive (or horribly wrong). Working mode of dkim: after dkim is activated, it will adopt a unique method of using encryption for confirmation. The domain contains the private key used to encrypt the message hidden in each email header and the public password decryption key added to the DNS record. These private keys will be kept confidential.
All e-mail systems that receive e-mail from this domain will obtain the public key from the DNS record and attempt to decrypt the hidden message. If successful, the email will come from the correct location
