While cloud providers such as Amazon Web Services (AWS), Microsoft Azure (Azure) and Google Cloud Platform (GCP) offer many cloud native security features and services, supplementary third-party solutions are essential to achieve enterprise-grade cloud workload protection from breaches, data leaks and targeted attacks in the cloud environment. Only an integrated cloud-native/third-party security stack provides the centralized visibility and policy-based granular control necessary to deliver the following industry best practices:
- Granular, policy-based IAM and authentication controls across complex infrastructures:- Work with groups and roles rather than at the individual IAM level to make it easier to update IAM definitions as business requirements change. Grant only the minimal access privileges to assets and APIs that are essential for a group or role to carry out its tasks.
- Zero-trust cloud network security controls across logically isolated networks and micro-segments – Deploy business-critical resources and apps in logically isolated sections of the provider’s cloud network, such as Virtual Private Clouds (AWS and Google) or vNET (Azure). Use subnets to micro-segment workloads from each other, with granular security policies at subnet gateways.
- Enforcement of virtual server protection policies and processes such as change management and software updates – Cloud security vendors provide robust Cloud Security Posture Management, consistently applying governance and compliance rules and templates when provisioning virtual servers, auditing for configuration deviations and remediating automatically where possible.
- Safeguarding all applications (and especially cloud-native distributed apps) with a next-generation web application firewall – This will granularly inspect and control traffic to and from web application servers, automatically updates WAF rules in response to traffic behavior changes and is deployed closer to microservices that are running workloads.
- Enhanced data protection – Encryption at all transport layers, secure file shares and communications, continuous compliance risk management and maintaining good data storage resource hygiene such as detecting misconfigured buckets and terminating orphan resources.
- Threat intelligence that detects and remediates known and unknown threats in real-time – Third-party cloud security vendors add context to the large and diverse streams of cloud-native logs by intelligently cross-referencing aggregated log data with internal data such as asset and configuration management systems, vulnerability scanners, etc and external data such as public threat intelligence feeds, geolocation databases, etc.
