What is SPF Permerror?

SPF=Permerror indicates that there is a fundamental problem with the SPF record, making it impossible to determine if the sending server is authorized or not.

What is the 10 DNS lookup limit?

During SPF check, every time an email is sent from your domain, your recipient’s email server performs DNS query requests, also known as DNS lookups to check the presence of authorized IP addresses in your DNS and match them to the ones in the received email’s return-path header. However, RFC limits the number of DNS lookups to 10. This is known as the 10 DNS lookup limit.

Am I exceeding SPF Too Many DNS Lookups limit?

Turn On Two-Factor Authentication For Your Emails

Email has been one of the most widely used ways of sharing data among professionals. Therefore, hackers have also become experts at retrieving data by breaching email security. The problem arises when companies don’t pay much attention to updating their email security methods and end up getting scammed.

As recorded by the Internet Crime Report, in 2020, there were 19,369 complaints about the Business Email Compromise (BEC). It resulted in adjusted losses exceeding $1.8 billion.

Two-factor authentication is built to make email accounts secure by adding a layer of security over username and password. The second layer of security can be anything like a fingerprint, a code, or a security token.

Here’s a guide on how to set up Two-factor authentication for emails and why it is important to make your accounts secure.

What is About Two-factor authentication?

Two-factor authentication (2FA) is an email security method, that requires users to provide two different authentication factors to verify their identity. used to enhance email security in addition to a strong password. It adds a randomly generated code to the login process, which you have to add every time before logging in to your account.

Once the code is activated, you can access your email accounts by entering this. This dual-factor authentication protects your associated email accounts as well as other applications. Even if someone else gets to know your password, they can’t log in without the code.

How Two-Factor Authentication (2FA) Works

Here is how 2FA typically works:

The first thing you need to do is to enter your username and password. It is the most common form of authentication. It involves something the user knows.
After the username and password are entered and verified, the system will request a second factor. This is usually something the user has such as a text message or a push notification.
Choose the method that seems most appropriate. Then enter the code from your phone, hardware token, or approve the push notification. If both the password and the second factor are correct, the system grants access to the user.

Common 2FA Methods

Here are some common methods used for 2FA:

SMS Text Message: A code is sent to your phone via text message.

Authentication App: Apps like Google Authenticator generate a code that changes every few seconds.

Biometric Verification: This uses your fingerprint, face, or iris scan to verify your identity.

Email Verification: A code is sent to your email address.

Hardware Token: A small device generates a code you can use to log in.

Push Notification: A notification is sent to your smartphone, and you approve the login by pressing a button.

Google Authenticator

A mobile security application, named Google Authenticator, is used to enhance the protection of email apps and websites by Two-factor authentication. It generates random codes on the user’s mobile. These codes provide a second layer of security for verification, enhancing the overall security.

Google Authenticator doesn’t use a text message approach for verification purposes. Rather, it generates a time-based, one-time code that is locally stored on the user’s device for sign-in purposes. It works as a decentralized approach to reduce unauthorized access to the email account.

Benefits of 2FA

The benefits of 2FA include:

Extra Security: 2FA adds another layer of security, making it harder for someone else to access your account.
Reduces Fraud: It helps prevent unauthorized access, reducing the risk of fraud and hacking.
Easy to Use: Once set up, it’s simple to use. Most times, it just means entering a code or tapping a button on your phone.

Downsides of 2FA

The downsides of using 2FA includes:

Inconvenience: It can be a bit slower to log in since you need an extra step each time.
Dependency on Devices: If you use your phone for 2FA and it’s lost, broken, or out of battery, you might be locked out of your accounts.
Technical Issues: Sometimes, there might be delays in receiving the code, or the authentication app might not work properly.

Importance of Email security

It is important to invest in the security of the email communications. It helps in identifying and filtering out malicious or spam emails, that may bypass standard spam filters. DMARC is one such added layer of security that prevents phishing attacks and unauthorized domain abuse. A multi-layered security approach helps organizations maintain productivity even when email threats prevail.

Spoofing and phishing are significant threats to the data shared through emails and can spread malware. Businesses can reduce the risk of having credentials and personal data compromised through various attacks by updating their email security procedures.

Conclusion

Using passwords to log into email accounts has long been considered, but they are no longer sufficient to protect the accounts from hackers. It is important to enhance the security of email accounts using all the possible security methods.

One of these methods is Two-factor authentication which provides an additional layer of security before logging in to your account. hether through SMS codes, authentication apps, or biometric methods, 2FA ensures that even if your password is compromised, your information remains secure.

Make 2FA a standard practice and encourage others to do the same, fostering a more secure online environment for everyone. Remember that in the current times, a little extra effort goes a long way in protecting what matters most.
