Data Packets

Security category No. 2: Data packets

Data packets deal with the data itself being transmitted between a device and a server. IT practice dictates that transmitted information should always be encrypted. Oftentimes, IT managers will recognize this necessary security precaution for other electronics but, unfortunately, fail to realize that their mobile solutions must reflect the same.

Without a definitive MDM (Master Data Management) strategy, mobile wireless solutions are extremely risky for a business as the probability of having information stolen becomes amplified. Handheld devices require the same level of security as desktop and laptop computers.

Is the data in clear text or is it encrypted end to end? Ultimately, this will make a difference in whether or not your data is secure. Some strategies secure wireless data transmission using an SSL connection, but data files themselves remain unencrypted. This means the data files are sent out across a secure network but data stored on the device is left unprotected.

Alternate security precautions encrypt files during transmission and also when stored on the device. This is the optimal, desired method for all enterprise mobile wireless data solutions. The RSA public keys use an FIPS (Federal Information Processing Standard)-level security model, in which data encrypted by the server's public key can only be decrypted with the server's private key. Data is thus secured end to end.
