Over the previous decade, electronic mail service has radically enhanced the overall productivity of business organizations operating all over the world. The use of email service has allowed firms, and business professionals to communicate with each other swiftly, conveniently, reliably, and inexpensively.
Security has been a Major Concern!:
However, standard electronic mail service has characteristically fallen short when it comes to providing high levels of security to business dealings. In fact, it is the major reason why all renowned firms must and should sincerely consider employing Secure Electronic Mail (E-Mail) services. In general, a standard Secure Email service can benefit companies by offering them with high standards of confidentiality, authentication, integrity, and non-repudiation.
Benefits of Secure Email Services:
Secure Email services provide high degree of confidentiality by encrypting all the text messages that are transferred over the high-speed internet connection. Encrypting provides privacy, and it also delivers integrity by assuring that the information has not been altered, while it is being transferred to the final destination system. The usage of closet encryption keys makes sure that only the company owners, or authorized administrators have access to the e-mail, and it comprehends the individual who transmitted the e-mail. Furthermore, non repudiation takes place since the recipient of the e-mail knows who has delivered the message.
Major Features of Secure Email Service:
There are many prominent standard features of secure Email service that actually formulate it as one of the best secure ways to deliver information over the Internet. The first and foremost aspect of course is encryption, which takes place when the information is transferred together with a secret key, through many mathematical methods that make the information completely unreadable. Later, to read the sent information, the procedure has to be totally reversed, and message needs to be decrypted by making use of the access key.
Another prominent feature of the secure Email service is the hash functionality. This function normally selects the primary plain text information of concerned length, and produces a distinctive fixed length output, which is normally referred to as a “message digest”. The basic concept here is that in case the input were altered by one bit, the “message digest” would be completely different.
Digital Signatures:
The usage of digital signatures is yet another major characteristic of the standard Secure Email service. Normally, digital signatures are produced by making use of hash functionality. First, a hash is carried out on the original information in order to produce a “message digest”. Later on, the information is signed by encoding the “message digest” with the secret key of the sender. This way, it permits the message recipient to check the integrity, non-repudiation, and authenticity of the message received.
Digital Security Certificates:
Digital certificate is another feature of the Secure Email service that guarantees high standards of Email security. A digital certificate in secure e-mail is a kind of official document, similar to a driving license, and it includes the public key of the owner, data that precisely recognizes the owner, and the endorser’s digital signature. The major objective of the secure e-mail digital certificate while sending a message is to assist others in verifying public key’s owner; it is extremely vital that the one who signs the digital certificate is trustworthy.
Common Vulnerabilities of Email Communication :
There are many common susceptibilities involved in standard e-mail communication, which includes spoofing and masquerading, Malware attacks, eaves dropping, password guessing, session hijacking, information leaks, data manipulation, middle-man attacks, and social engineering. All these common vulnerabilities are precisely taken care of, in case of secure email service, thus ensuring high levels of security throughout the process of email transmission from sender’s end to receiver’s end, leaving no margin for error.
