What is cloud data security? Benefits and solutions
Cloud data security is the practice of protecting data and other digital information assets from security threats, human error, and insider threats. It leverages technology, policies, and processes to keep your data confidential and still accessible to those who need it in cloud-based environments.
Cloud computing delivers many benefits, allowing you to access data from any device via an internet connection to reduce the chance of data loss during outages or incidents and improve scalability and agility. At the same time, many organizations remain hesitant to migrate sensitive data to the cloud as they struggle to understand their security options and meet regulatory demands.
Understanding how to secure cloud data remains one of the biggest obstacles to overcome as organizations transition from building and managing on-premises data centers. So, what is data security in the cloud? How is your data protected? And what cloud data security best practices should you follow to ensure cloud-based data assets are secure and protected?
Read on to learn more about cloud data security benefits and challenges, how it works, and how Google Cloud enables companies to detect, investigate, and stop threats across cloud, on-premises, and hybrid deployments.
Cloud data security protects data that is stored (at rest) or moving in and out of the cloud (in motion) from security threats, unauthorized access, theft, and corruption. It relies on physical security, technology tools, access management and controls, and organizational policies.
Why companies need cloud security
Data privacy, integrity, and accessibility
Cloud data security best practices follow the same guiding principles of information security and data governance:
What are the challenges of cloud data security?
Strong cloud data security measures allow you to maintain visibility into the inner workings of your cloud, namely what data assets you have and where they live, who is using your cloud services, and the kind of data they are accessing.
Easy backups and recovery
Cloud data security can offer a number of solutions and features to help automate and standardize backups, freeing your teams from monitoring manual backups and troubleshooting problems. Cloud-based disaster recovery also lets you restore and recover data and applications in minutes.
Cloud data compliance
Robust cloud data security programs are designed to meet compliance obligations, including knowing where data is stored, who can access it, how it’s processed, and how it’s protected. Cloud data loss prevention (DLP) can help you easily discover, classify, and de-identify sensitive data to reduce the risk of violations.
Organizations need to be able to protect sensitive data whenever and wherever it goes. Cloud service providers help you tackle secure cloud data transfer, storage, and sharing by implementing several layers of advanced encryption for securing cloud data, both in transit and at rest.
Cloud data security reduces total cost of ownership (TCO) and the administrative and management burden of cloud data security. In addition, cloud providers offer the latest security features and tools, making it easier for security professionals to do their jobs with automation, streamlined integration, and continuous alerting.
Advanced incident detection and response
An advantage of cloud data security is that providers invest in cutting-edge AI technologies and built-in security analytics that help you automatically scan for suspicious activity to identify and respond to security incidents quickly.
