In the era of cloud computing, one of the strongest ways people can protect their data is by encrypting it. SQL Server 2014, Microsoft's latest database language solution, provides users with two effective security implementation methods, prompting some professionals to enroll in SQL training.
Twenty years ago, when the data center reigned supreme over intelligence storage, encryption wasn't necessarily a must-have. Now, companies are accessing the majority of their applications and files through cloud environments, making the protection technique a necessity.
According to Smart Data Collective, enterprises require complex sets of instructions to encode the data transferred through email and stored on cloud platforms. These algorithms aren't the easiest to create – only some of the most ingenious mathematicians can develop unique codes that aren't easily deciphered by those with ill intentions.
Why it's needed
Enterprises skeptical of employing encryption need only look at the data breaches sustained by Neiman Marcus, Target and eBay over the past year. Every day, customers entrust their personal financial information to retailers, so it's a merchant's responsibility to assure that hackers and malware won't be able to gain access to a person's credit or debit card number.
If people don't feel confident in an organization's ability to secure their data, then they're likely to bring their business elsewhere. Why risk losing all that hard-earned money just to buy a toaster at Merchant A when Merchant B offers the same appliance and employs better data security techniques.
Transparent data encryption
Database Journal described TDE as one of the more common encoding processes professionals can utilize when working with SQL Server. The method implements no changes to original application codes, meaning that there's no structural impact on the programs being encrypted. The source outlined key features Microsoft training enrollees should know:
- Encryption of information in pages before it's transcribed onto disks
- Decryption of data when it's read off of storage devices at the input/output transaction
Cell Level Encryption
Also known as Granular Level Encryption, Database Journal asserted that the technique eliminates those viewing the information through a buffer pool from those discerning it. One of the signature differences between CLE and TDE is that applications being encrypted require a code change. Primary functions include:
- The ability to change the data type to VARBINARY
- Performance which depends on the number of columns administrators plan on encrypting
The fact that SQL server gives database managers the ability to use two encoding strategies is incredibly useful. Those who want to obtain extensive knowledge in the program should consider enrolling in Microsoft certification courses.
