On a consumer level many people want their personal information to be secure when it’s in the hands of an organization. This desire extends to the enterprise, where robust security of data is crucial for retaining customers and establishing trust with employees and stakeholders.
Data security is the safeguarding of digital data from corruption, damage and theft during its entire life-cycle. Data security encompasses everything from hardware, storage devices, software and user devices to access control and access control. It also covers ensuring that policies and procedures are in place to prevent data breaches.
Security of data is generally achieved by encryption, data masking and resilience. The encryption of sensitive information is essential for all stages, including in storage, transport and use. It makes the data inaccessible to anyone else. Data masking complements encryption by replacing sensitive digital data with fake information to serve purposes such as database administration, research and development, software testing and training of users.
Resiliency requires backups and copies to protect critical data which can be restored quickly in the event of an incident or a breach. It also requires the removal of physical storage media, such as USBs and external drives (and even printed documents and files) on a regular schedule to avoid the information from being exposed by hackers.
Data security is a top priority for companies because the consequences of a major data breach can cost them millions in cost of recovery and forensic expenses. It could result in compliance fines, and cause lasting damage to their reputation and customer loyalty. It’s also a mandatory requirement, as the General Data Protection Regulation (GDPR) and California Consumer Privacy Act require companies to safeguard personal data.
