Secure e-mail service provider

To protect customer accounts and data from attackers, email service providers have email protection measures in place. These steps involve email servers with robust frameworks for password and authentication, secure emails (both inbox and in transit); firewalls for web applications; and spam detection tools.

What is E-mail Security?

As a platform for delivering viruses, spam, and phishing attacks, e-mail is prominent with attackers. To manipulate users into disclosing personal information, they use misleading texts, culminating in identity fraud. They tempt users to register files or click URLs on the user's computer that allow maliciously (like email malware). For threats, anyone wants to penetrate network architecture and hack sensitive customer information, email is often a key entry point. The characteristics of E-mail security are often flexible, and according to the user's requirements, some of the common features are given below-

Features of the e-mail service provider

It's not like, all reliable email services are confidential and protected indeed. Several free alternatives may do further damage. Therefore, it meets some or most of the following requirements when looking for the most reliable email provider:

Some of the most common features of e-mail service providers are mentioned-below:

1. End-to-end encryption

No email service can call itself secure without end-to-end encryption. Your message is only encoded till it hits Gmail or yahoo mail when you're using a standard service. If end-to-end encryption is used, the text can only be read by the sender and the receiver. The most popular end-to-end encryption for protected messages is the so-called Pretty Good Protection or PGP in general.

2. Two-factor-authentication (2FA)

It gives you great protection and protects your accounts in case anyone learns your password. You find it more difficult to hack into your inbox by incorporating anything that you must have, like a mobile. There are several 2FA options, varying from Google and other SMS to authorization apps.

3. Stripping headers from metadata.

Each message includes the data of data (metadata), like the internet browser, and even the receiver. For the sake of the sender and recipient confidentiality, protected email providers wipe out the header's metadata.

4. Position of the server.

Many nations are not private information-friendly. Some even have regulations for data protection that enable your personal information to be retained for a certain time. Representatives of the Five Eyes intelligence organization are the USA, United Kingdom, Canada, and Australia. They exchange intelligence information about indicators and are among the hardest locations for a safe email provider to enroll.

The Need of secure e-mail service

The benefits of using a protected email service must be evident to you. When you still have some questions, although, while switching to Gmail, please ensure to take a look at the following considerations:

1. Protect the emails

After the message hits their servers, Gmail, Hotmail, and other popular services don't encode your confidential information. This implies that they can translate them and make reading easier for attackers as well.

2. Metadata header hiding

It doesn't immediately imply covering the headers with metadata if your daily email system authenticates your mail. It also covers your email account, laptop, browser, and network, as well as the receiver.

3. Do not be a commodity.

If your email is good and free to use, there may be some possibilities that you are treated as a commodity. However, very few users realize that Gmail constantly searches the mailbox for words and utilizes them to display customized advertisements. By using this way, you are helping Google to earn money from your data with the help of Gmail.

4. In a private information-friendly place, save your emails.

The USA and any cognitive ability-sharing nation with Fourteen Eyes will someday wish to access your mailbox. If the vendor's database is in one of those nations, it would be much quicker to do that than to obtain access to any of Switzerland's nuclear bunkers.

Ultimately, please remember that the email system is as protected as the passwords you have selected. If someone can hack your password in a couple of minutes, all end-to-end authentication and no-logs regulations go over the roof.

Working of secure email service

End-to-end authentication is the distinguishing characteristic of encrypted messaging. It implies that there is no option for the mail service or a third party to decode your letter, which can only be achieved by the receiver. On the counter, your messages can be read by any standard email service provider such as Google (they are screening emails for words already!) and making them simpler for attackers to get.

For protection, Pretty Good Privacy (PGP) and Secure/multipurpose internet mail extension (S/MIME) are the most prominent options. PGP incorporates symmetrical and asymmetrical protection, whereas S / MIME provide the certificates that must be approved by the certification authority at the regional or public level. Utilizing a certificate guarantees that you are the message provider and that it has not been interfered by others.

Because of the encryption, neither perpetrators nor the government, like email accounts, will peer into your communication or metadata.

Encryption Levels

Here, we have discussed some different types of encryption levels that are used to secure email communication.

  • Transport-level Encryption

Transport-level authentication guarantees that your email moves securely across the network, as discussed before. After all, the provider will see the non-encrypted edition once it appears on their server, it would not be sufficient to allow safe mail transmission. Although the latter is still used, Transport layer security, is counterpart of Secured socket layer. It is configured for encrypting emails (IMAP, SMTP) as well as other protocols, like HTTP (Hyper-text transfer protocol) or FTP (File transfer protocol), on top of TCP (Transmission Control Protocol). It is still not included in all mail systems, unfortunately. For a frequent user, this may not be obvious since there is no easy ability to determine when transport-level encryption is in effect while using mail, unlike an internet browser displaying a green lock or equivalent icon.

  • End-to-end Encryption

End-to-end encryption means that your text can be decrypted neither by the email service provider nor any other third party. Only the sender and the receiver contain the public and private keys that are required to unlock it.

Working of End-to-end encryption

You encode the text with the public key of your partner. Now, this can only be decoded with the private key of your partner. Before it hits your partner, your encoded data passes via servers. He or she utilizes the private key to decode your message in exchange.

  • PGP email encryption

There is no need for users to share private keys; PGP email authentication incorporates a hashing algorithm, symmetric encryption and public-key authentication. Behind this, a safe email system does it, so you do not have to think about the pros and cons.

How the PGP operates

Just after the session key is created by Pretty Good Privacy protocol, the shared key of the receiver encodes it. The sender provides this encoded session key and it is decrypted with his or her private key by the recipient.

Ultimately, the non-encrypted session key is used by the receiver to interpret the email.
