What is Cloud Security?
Cloud Security focuses on protecting data, applications and infrastructure in the cloud, often leveraging technologies that secure remote access from different devices or locations. It also involves a framework for governance and compliance to ensure that the company is in line with any relevant industry regulations.
With more business processes moving to the cloud, attackers are increasingly seeing cloud-based targets as a lucrative path to bigger gains. The heightened attack surface created by these environments has made them a much more attractive target, with cyber-attacks like password compromises, Zero-Day attacks, account takeovers, malware and ransomware becoming a daily reality.
As the need for flexibility grows, so does the complexity of securing cloud-based assets. This is exacerbated by newer approaches to application development and deployment, such as automated Continuous Integration/Continuous Deployment (CI/CD), distributed serverless architectures and ephemeral assets such as Functions as a Service and containers.
The responsibility for securing the cloud is shared between the CSP and the customer, but it’s important to understand where each party’s responsibilities begin and end to build a resilient and effective cloud security strategy. To do so, you need a clear view of the entire environment and a holistic approach to security that includes identity and access management (IAM), network controls, and a layered approach to protection that combines firewalls, VPNs, Zero Trust network access and cloud-native solutions like encryption and access control.
Even with the most robust security measures in place, data breaches and disruptive outages can still happen, so disaster recovery solutions are a key part of any cloud security solution. This includes the ability to backup data regularly, so that if one of your providers experiences a security incident, you can restore full functionality quickly.
