Cloud-based infrastructure requires a similar level of security as an organization’s on-prem environment. Cloud network security is a foundational layer of cloud security and is vital to protecting the data, applications, and IT resources deployed within enterprise cloud environments as well as the traffic flowing between cloud deployments and the enterprise’s intranet and on-prem data centers.
On-prem enterprise networks use network security solutions for advanced threat prevention, to restrict access to corporate systems, enforce security policies, and perform internal segmentation of corporate networks. Cloud network security provides similar enterprise-grade protection to cloud infrastructure and networks.
As companies move to adopt cloud-based infrastructure, they need to protect these resources in accordance with corporate security policies and applicable regulations. Traditional, perimeter-based defenses cannot effectively protect cloud-based infrastructure, and the cloud vendors’ security tools built into most public and private cloud offerings do not meet enterprise security requirements.
Cloud network security solutions close a foundational security gap in the cloud. They enable companies to achieve the same level of security monitoring and threat prevention that they have in their on-premises environment despite the dissolving network perimeter. This is essential to an organization’s ability to fulfill its duties under the cloud shared responsibility model and to ensure corporate cybersecurity and regulatory compliance.
Customers who use the same security vendor for their on-prem and cloud deployments should ensure they can manage all their network security from a single pane-of-glass, thus increasing efficiency and reducing TCO as well as corporate risk.
Cloud environments use software-defined networking (SDN) to route traffic through an organization’s cloud-based infrastructure. Cloud network security solutions integrate with cloud platforms and virtualization solutions and deploy virtual security gateways in order to achieve the visibility and control required to perform segmentation, security monitoring and advanced threat prevention for network traffic. These virtual security gateways are similar in function and capability to on-prem security gateways, but are virtual and hosted in the cloud.
A cloud network security solution should provide an organization with a similar level of security in the cloud as it has in its on-prem infrastructure. To achieve this, a cloud network security solution must have certain key capabilities, including:
Manually managing the security tools and configuration options natively available in cloud environments can be complex and does not provide the level of security needed by the modern enterprise. Key benefits of a cloud network security solution include:
As companies move to the cloud, certain cloud service models are better suited to addressing certain business and security needs. Companies need to choose between public and private cloud infrastructure for various use cases and often deploy a hybrid, multi-cloud environment that spreads resources over public and private cloud environments and on-prem infrastructure.
A cloud network security strategy should provide robust security for both public cloud and private cloud environments. This involves securing not only north-south data flows entering and leaving the cloud environment but also east-west flows between different cloud-hosted resources within the same cloud deployment (also called “lateral movement”).
