Email security does not end with password for accessing the email accounts message content can be validated and secured, sender identity can be authenticated, authorization of email senders can be maintained, and the integrity and functionality of the email app itself can be better secured.Email security is a software that provides protection to the organization’s email infrastructure.
Email is prone to the disclosure of information. Most emails are currently transmitted in the clear (not encrypted) form. All emails sent using Gmail or Outlook are encrypted by default. It is possible to send an unencrypted email using Gmail but a warning icon will appear in the address bar. By means of some available tools, persons other than the designated recipients can read the email contents.
Email encryption can rely on public-key cryptography, in which users can each publish a public key that others can use to encrypt messages to them, while keeping secret a private key they can use to decrypt such messages or to digitally encrypt and sign messages they send.
