Cloud Network Security

Easily integrate a cloud network security solution across your organization’s hybrid network, with the Perimeter 81 solution.

What is Cloud Network Security?

Cloud network security is a category of tools and capabilities that address the virtualized network security model. This includes cloud security model integration and threat modeling to provide an enhanced level of endpoint security for networks and applications. 

Cloud network security services can provide unified access to remote servers, control access to infrastructure resources and establish secure connections between the internet, private clouds and public cloud providers. The services also integrate network and application security capabilities within the cloud security model to provide robust coverage for both network and cloud applications.

The cloud network security model benefits from the integrated capabilities of Secure Access Service Edge (SASE) and SD-WAN technologies that empower organizations to deploy their networks with self-service controls and security options.

SASE security services also include traditional endpoint security services and solutions that analyze network traffic for threats such as phishing attacks, malware and malicious traffic. 

The advantages of cloud network security includes the flexibility to deploy IT resources across multiple sites to form a secure, global virtualized network topology. Moreover, continuous monitoring and alerting of network security configurations and resources eliminates costly network management tasks.

Cloud Network Security Components

Cloud network security solutions provide services that help harden networks, applications and services.

Firewalls and security groups provide instance-level security, letting you effectively manage traffic in multiple cloud networks, helping to avoid DDoS attacks and data theft. encryption key managers are other valuable network tools that allow you to generate and store data encryption keys in one secure cloud-based management solution.

Software Defined Networks (SDNs) represent the central component of cloud network security architectures.They separate the control plane, also known as the logical network layer that makes traffic routing decisions, from the underlying data plane, the mechanism that forwards network traffic through routers.

SDNs offer network traffic programmability and control with policy management while leveraging network hardware resources from public cloud providers.

SDNs connected by encrypted tunnels make up sets of network services that provide enhanced functionality across virtualized networks.

Traffic moving across an SDN can be classified based on application or service type and then prioritized and forwarded based on centrally-managed policies that optimize network traffic.

SDN solutions enable IT administrators to integrate network infrastructure and security controls together ranging from internet traffic prioritization and DNS filtering to firewall creation and threat management, all via a web portal.

By eliminating the need for expensive and proprietary networking hardware, SDN technology also reduces the physical infrastructure overhead so that any organization, from small and medium businesses (SMBs) to enterprises, can quickly deploy highly secure networks either locally or globally.

SD-WAN and Cloud Network Security

SDNs are the key component of cloud network security architectures that encompass the integrated capabilities of both Secure Access Service Edge (SASE) and SD-WAN technologies.

An SD-WAN is also known as a type of software-defined wide-area network. It’s virtualized so that the network is abstracted from datacenter or branch office hardware to create an easily configurable and scalable overlay wide area network distributed across local and global sites. 

The SD-WAN implementation of Software Defined Network (SDN) technology makes it more reliable, scalable and cost effective than VPN-based WAN solutions because it takes a software-based approach to building and extending enterprise networks beyond the core SDN.

Organizations today can use SD-WAN solutions to connect branch offices to their corporate networks instead of using traditional and expensive multiprotocol label switching (MPLS) connections, firewalls or proprietary hardware.

SD-WAN virtual appliances, connected by encrypted tunnels, connect to sets of network services that provide enhanced functionality across the virtualized network. Moreover, traffic reaching an SD-WAN appliance can be classified based on application or service type which is then prioritized using centrally-managed policies to optimize network traffic.

SD-WANs have many benefits for distributed organizations that leverage the cloud ranging from network topology simplification, internet traffic prioritization, and cost reduction to scalability and integrated security.

Central SD-WAN management with traffic routing based on application policies lets IT managers automate deployment and configuration processes thereby reducing the complexity and resources required to manage a WAN. Enterprise applications can also be aggregated, integrated and controlled from a SD-WAN portal, further simplifying SD-WAN management.

With internet traffic prioritization, SD-WANs can identify critical data as it moves through the network, supplanting web surfing and video streaming, which in turn boosts network performance and efficiency. Content filtering capabilities can restrict access or allocate bandwidth to selected sites resulting in additional network efficiency.

Finally, because SD-WANs eliminate physical equipment, organizations can save the administration time and labor costs normally associated with networking hardware deployments. In addition, replacing expensive MPLS with cloud-based broadband connectivity options further reduces costs.
