People would like to know that their private information is secure when it is in the hands of an organization. This expectation extends to corporate level, where data security is essential to keep customers happy and establishing trust with employees and other stakeholders.
Data security involves protecting digital data from loss, corruption, and theft throughout its lifespan. It encompasses everything from hardware and storage devices to software, user devices and access control. It also involves ensuring that policies and procedures are in place to prevent data breaches.
Data security is achieved primarily through encryption, data masking and resilience. The encryption of sensitive data in use and while in transit since it renders the content illegible to unauthorized entities. Data masking can be used to complement encryption by replacing sensitive digital information with fake information for reasons like database administration, research and development software testing, as well as training of users.
Resiliency involves having backups and copies of critical data that can be restored quickly in the event of an emergency or breach. It also implies disposing of physical storage devices, such as external drives and USBs (and even printed files and documentation) regularly on a regular basis to avoid the information from being discovered by hackers or falling into the wrong hands.
Security of data is a top concern for businesses because an incident that is well-publicized could cost them millions of dollars in cost of recovery and forensic expenses. It can also lead to penalties for compliance and could result in lasting damage to their reputation and customer loyalty. It’s also a regulatory requirement in that the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act require companies to safeguard personal information.
