How Secure Email Increases Business Productivity and Information Security

Electronic mail has dramatically increased productivity for business over the past decade. Its use has enabled companies and individuals to communicate quickly, reliably, easily, and cheaply. However, standard e-mail has typically lacked in the area of security. It is for this reason that companies should seriously consider implementing Secure E-mail strategies. Secure E-mail can benefit businesses by providing them with confidentiality, integrity, authentication, and nonrepudiation.The confidentiality of secure e-mail occurs by encrypting the messages that are sent over the Internet. This provides privacy. Encrypting also provides integrity by ensuring that the data has not been modified while in transit. The use of secret encryption keys ensures that only the owners know and have access to the e-mail, and knows the person who sent the e-mail. In addition, nonrepudiation occurs due to the recipient of the message knowing who sent the message.There are several features of secure e-mail that make it a secure way to send data. The first is encryption. Encryption occurs when the data is sent along with a key, through multiple mathematical formulas that make the data unreadable. In order to read the data, the process has to be reversed using the appropriate key.Another feature is the hash function. This function takes the original plaintext data of any length and creates a unique fixed-length output. The result of the hash function is known as a message digest. The principle here is that if the input were changed by a single bit, the message digest would be different.The use of Digital signatures is also an important feature of secure e-mail. Digital signatures are made by using the hash function. A hash is performed on the message to create a message digest. Then, the message is “signed” by encrypting the message digest with the sender’s private key. This allows the receiver to verify the message’s integrity, authenticity, and nonrepudiation.Digital Certificates are another feature that ensures e-mail security. A digital certificate is a type of credential/official document, like a driver’s license, that consists of the owner’s public key, information that uniquely identifies the owner, and the digital signature of an endorser, which states that the public key actually belongs to the person in question. The purpose of the digital certificate is to help others verify that the owner of the public key is who he claims to be. It is important that the authority who signed the certificate is trusted.A combination of encryption methods are also a feature that can be utilized in secure e-mail. PGP (pretty good privacy)/MIME (multipurpose Internet mail extensions) are said to be hybrid cryptosystems because they overcome the shortcomings of both public key and conventional cryptosystems. PGP is an encryption technology that is currently the standard for e-mail encryption, and S/MIME was designed to add security to e-mail messages in MIME format by offering authentication using digital signatures and privacy using encryption.There are several steps PGP and S/MIME encryption systems take to secure e-mail messages before they are sent. They are: The message is compressed (only with PGP), A session key is created, The message is encrypted using the session key with a symmetrical encryption method, The session key is encrypted with an asymmetrical encryption method, The encrypted session key and the encrypted message are bound together and transmitted to the recipient. These same steps are used in reverse order to decrypt the message.There are several vulnerabilities involved in e-mail communication. Some of the most common are: eavesdropping, spoofing and masquerading, man-in-the-middle attack, session hijacking, data manipulation, Malware, social engineering, password guessing, and information leaks.- The vulnerability of eavesdropping is solved by e-mail encryption for communications that require confidentiality.- Spoofing and masquerading are solved by the use of Digital certificates issued by a trusted certificate authority that proves to the customer/receiver that the sender of an e-mail is who he claims to be.- Man-in-the-middle attack or session hijacking tricks an e-mail server to send their data through a third note. This is countered by digitally signing data, ensuring that both parties authenticate each other. Encrypting the e-mails will also counter this vulnerability.- The problem of data manipulation can be countered by e-mail encryption, which stops both the reading and manipulation of e-mails, and digital signatures, which ensures that if the data was changed then the receiver would know.- Malware is malicious software; viruses, Trojan horses, backdoors, and worms. This is countered by the use of virus filtering software.- Social engineering uses trickery on people instead of on software. This is also solved by the use of e-mail encryption and digital signatures.- The countermeasure against the attack of password guessing is to choose a strong passphrase for your certificate or key.- Finally, information leaks can be countered by training users on acceptable use of e-mail and to use an e-mail filtering solution. These countermeasures can also combat the negative and corrosive effects of spam, hoaxes, and e-mail born viruses.In conclusion, standardised email can significantly increased productivity for your company. Its use can enable you to communicate reliably, easily, and affordably. In addition, utilizing secure e-mail can provide you with confidentiality, integrity, authentication, and nonrepudiation.Works Cited
