The security of email from unconstitutional access and intrusion is referred to as electronic privacy. In nation states with a legitimate security of the confidentiality of communication, email has now taken the place of letters and thus with authorization secured from all forms of spying.
The Internet is an extensive network of computers, much of which is unguarded against malevolent attacks. From the time an email written by the sender to the time it is read by the recipient, it moves through this vulnerable Internet, exposed to a range of electronic threats.
Many users consider that email privacy is inbuilt and fail-safe; they assume it to be as safe as the postal mail. While email is without a doubt traditionally secured by a password system, and basically this superficial layer of protection is generally not enough to make certain substantial security.
Businesses are nowadays more progressively relying on electronic mail to communicate with their clients and associates. Since, more mission-critical data is transmitted on-line; the requisite for email privacy becomes more indispensable.
