Many people want to know that their personal data is safe when it is stored by an company. This is also true for the enterprise, where strong security of data is crucial to retaining customers and building trust with employees and other stakeholders.
Data security is the safeguarding of digital data from corruption, damage and theft throughout its life cycle. It encompasses everything from hardware and storage devices to software, user devices and access control. It also includes ensuring policies and procedures are in place to stop data breaches.
Data security is achieved primarily through encryption, data masking, and resilience. The importance of encryption is in the data when in use, or in transit because it renders the data unreadable to non-authorized entities. Data masking enhances encryption by replacing sensitive digital data with fake information for purposes such as database administration, research and development software testing, as well as training of users.
Resiliency is about having backups of crucial data that can be quickly restored in the event of an incident. It also involves disposing of physical storage media like USBs and external drives (and even printed documents and files) regularly to prevent the information being discovered by hackers.
Data security is a top priority for businesses because the consequences of a major data breach can cost them millions in recover costs and forensic costs. It can also lead to penalties for compliance, as well as result in lasting damage to their reputation and customer loyalty. It’s also a mandatory requirement as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act require companies to safeguard personal data.
