Email Security Practices

Standard Email Security Practices

Email security is a crucial part of your online business. If you don’t have an email security measure, you could be putting yourself at risk for cyber-attacks and data theft.

Fortunately, there are several email security practices. Each one of these practices has its way of protecting your mailing information and keeping it secure from prying eyes.

These practices include encryption, which protects your messages from being read by anyone who might intercept them as they travel across the network; and authentication, which verifies that the person on the other end of the message is who they say they are.

Spam Filters

Spam is a type of unsolicited email that often includes harmful or deceptive content. Spam can be sent by :

  • Spammers, who are trying to sell you products or services
  • Scammers, who are trying to steal your information and use it for financial gain;
  • “Black hat” hackers, are looking for vulnerabilities in your system that they can exploit to access your data and cause other problems.

Spam filters are designed to identify and block unwanted emails. This is accomplished by examining the content of an email and looking for certain patterns. When a spam filter identifies a message as spam, it will prevent it from being sent to the recipient’s inbox.

There are many different types of spam filters available, including:

  • Blacklist-based filters that check messages against a list of known spammer addresses
  • Keyword-based filters that check messages based on keywords or phrases
  • Anomaly-based filters that look for potentially malicious content in messages
  • Heuristic-based filters perform a combination of other types of analysis to determine whether or not a message is a spam

Anti-Virus Protection

Viruses are one of the biggest threats to email security today. They can infect an entire network by corrupting files, stealing passwords and personal data, or spreading themselves across multiple systems through infected attachments sent through email. These viruses can wreak havoc on your company’s email servers and applications if they’re not detected quickly enough.

The best way to protect your emails is by implementing anti-virus protection systems within the email server. An anti-virus system checks all incoming emails for viruses, worms, and Trojan horses.

Email Attachment Control

Phishing emails are designed to trick people into giving up their personal information by clicking on a link in an email. The attachment to these emails often contains malicious software that could let the scammers access your computer and collect your banking information.

The best way to protect yourself from phishing attacks is by using an email attachment control system. These systems allow you to see what type of files are being sent to your inbox before they are opened by you or someone else on your team. They also help you verify whether or not the file was sent from the sender’s address before allowing it through security filters like antivirus software or spam filters.

Email Encryption

Unencrypted emails are also vulnerable to hackers because they can be easily deciphered. This means that if someone were to intercept an unencrypted email, they could read it without having to use a password or key. Encrypting emails ensures that only the intended recipient can read them, making them more secure from hackers.

Email data encryption works by scrambling data so it becomes indecipherable without a special key. This means that even if someone steals an email from your server and reads it, they will not be able to make sense of what’s in the email without having access to the key needed to decrypt it—and only the intended recipient would have that key.

Advanced Email Security with DMARC

Even if you know what is email security and how important it is for your business; you may still fall short of providing optimum security. That’s when DMARC, a next-generation email security protocol for businesses, schools, and corporate organizations comes in. It is an advanced security mechanism designed to protect businesses against email spoofing. If you want to secure your email communications, DMARC is the most efficient tool for this purpose. 

By implementing DMARC, you can ensure that all of the emails are sent from the domain (or legitimate recipient) you want them to be delivered from.

DMARC uses two other technologies, SPF and DKIM, as well to work together as a powerful whole.

SPF identifies where an email came from by checking the IP address of the sending server against a list of authorized servers for your domain.

DKIM creates a digital signature inside the message header. The signature is verified by checking against a public key that’s stored on the sender and recipient’s servers each. Therefore, it provides another layer of security by checking if someone has ownership over the domain they are sending the email from or if they are just trying to impersonate a legitimate sender.

What Makes DMARC An Ideal Email Security Solution?

DMARC is a modern email security solution that is short for Domain-based Message Authentication, Reporting, and Conformance (DMARC) standards to reduce the risk of phishing and direct-domain spoofing in your emails.

It works by sending a special header when an email is sent that identifies the sender, adds additional features to improve email security, and allows you to set up an effective response if someone attempts to send phishing or malware-tainted messages through your account. It does this using a series of checks and balances based on information about the sender, recipient, subject line, body text, and other specific characteristics of each message.

The DMARC protocol requires each message to carry an authentication tag, which is an identifier for the sender domain. If the recipient of an email does not have access to that tag, then the recipient machine will not be able to verify whether or not the message came from a legitimate source.

How does DMARC Level Up Email Security?

DMARC is a great email security solution because it’s built on a foundation of strong authentication, trusted third parties, and a rules-based policy.

The result is that DMARC provides you with a solid foundation for managing your email communications, while also giving you the ability to set up complex policies that allow you to manage your messages even if they’re coming from untrusted sources.

Here is how DMARC spruces up email security:

1. One of the most prominent features that make DMARC different from other email security solutions is that it looks at the metadata of the email (such as who it was sent from). Therefore, it does not only prevent spam or phishing attacks. But also authenticates messages before they are sent and ensures only legitimate recipients can receive them.

2. It’s effective because it works on both the source side (the content of the emails, including attachments) and the target side (the inbox of the recipients).

3. It uses a variety of methods to identify suspicious messages, including IP addresses and DNS lookup data, which means that it doesn’t rely on a single point of failure like other solutions do.

4. DMARC works by identifying suspicious emails, then blocking them from reaching their intended recipients. It uses a variety of methods to identify suspicious messages, including IP addresses and DNS lookup data, which means that it doesn’t rely on a single point of failure like other solutions do.

5. DMARC works with all types of email providers and can be implemented for both small businesses and large enterprises. It’s also very easy to customize, meaning you can adjust its policies (like p=reject or p=none) that match specific types of emails with different actions based on their content.
