What is Data Security?

Data Security concerns the protection of data from accidental or intentional but unauthorized modification, destruction, or disclosure through the use of physical security, administrative controls, logical controls, and other safeguards to limit accessibility. Ways of securing your data include:

  • Data Encryption – converting the data into a code that cannot be easily read without a key that unlocks it.
  • Data Masking – masking certain data areas so personnel without the required authorization cannot look at it.
  • Data Erasure – ensuring that no longer used data is completely removed and cannot be recovered by unauthorized people.
  • Data Backup – creating copies of data so it can be recovered if the original copy is lost.


You must know what normal behavior looks like to detect abnormal network behavior. Behavioral analytics tools automatically discern activities that deviate from the norm. Your security team can then better identify indicators of compromise that pose a potential problem and quickly remediate threats.


Organizations must ensure that their staff does not send sensitive information outside the network. Data loss prevention, or DLP, technologies can prevent people from illegally uploading, forwarding, or even printing critical information.

Application security

Any software you use to run your business must be protected, whether your IT staff builds it or you buy it. Unfortunately, any application may contain holes or vulnerabilities that attackers can use to infiltrate your network. Application security encompasses the hardware, software, and processes you use to close those holes.
