How can you safely protect against e-mail espionage?

19.02.2014 | Uncategorized

The worldwide web has fundamentally changed the shape of society of the past twenty years. It has offered a levelled playing field for everybody: allowing private individual to connect with other people around the world with no intermediation from broadcast networks, and enabling businesses to compete against each other on equal terms.

As with any system, some participants will see this equal competition as a threat, and look for an unfair advantage. This is just as true on the internet as in the real world, where recent disclosures have uncovered the mass collection of personal data by certain organisations. Email espionage, and the spying out of data have led to an unprecedented interest in web security services. Whilst a private email may be a source of embarrassment if its security is compromised, a stolen business correspondence may result in lost contracts, earnings, and intellectual property.

For this reason, many companies are adopting a more advanced email encryption system for their existing infrastructure. With a product like gpg4o, users are able to retain their existing email services, and introduce an added layer of email encryption security to protect their documents and datasheets.

As with all infrastructure services, choosing the right product to match the demands is the key. With gpg4o, users are able to take advantage of the open source, OpenPGP technology in an easy-to-install format. Security specialists are increasingly advocating the use of open source technology over proprietary software, for the simple reason that the source code is freely available and may be scrutinised for errors, flaws, or deliberately-created back doors. “PGP” is an acronym for “pretty good privacy”, an encryption standard that has existed and remained secure since 1991.

Virtually everybody uses the internet in their everyday life. But until recently, few understood the need for encryption, or indeed how encryption works. One of the best examples when considering email security is to imagine a padlocked box which needs delivering to a recipient. The sender has the key that opens the padlock, and sending that key to the recipient would be a breach of security. So instead, he sends the locked box, and the recipient then, in turn, attaches their own lock to the box and returns it to the sender. With two locks now in place, the sender can remove his initial lock, and return it once more to the recipient, who has the key for the last remaining lock, as it is his own.
