Over the last decade, cloud computing has become the backbone of modern business, transforming how organizations operate and scale.<\/span>\u00a0<\/span><\/p>\n

Companies rely heavily on cloud services, with most of their applications and workloads migrating to efficient platforms like AWS due to the increased remote working requirements and demand for scalable, flexible, and cost-effective solutions that support business continuity and growth.<\/span>\u00a0<\/span><\/p>\n

In this cloud setup, Amazon Virtual Private Cloud (VPC) enables businesses to create private network environments, giving them control over network setup, traffic management, and connections to on-site systems.<\/span>\u00a0<\/span><\/p>\n

However, monitoring and securing the traffic within these environments can be challenging.<\/span><\/p>\n

Why is that?<\/span>\u00a0<\/span><\/p>\n

Monitoring, analyzing, and securing such complex environments is difficult because so much data flows to and from the cloud, as well as internally, including sensitive information. This makes the cloud, i.e., the VPCs, one of the prime targets for attacks.\u00a0<\/span>\u00a0<\/span><\/p>\n

This is where we need to consider cloud network traffic analysis, including traffic mirroring, and advanced security monitoring strategies.<\/span>\u00a0<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
