How SASE Enhances Cloud Security

Digital businesses need agility and scalability to deliver the user experiences they want while simultaneously maintaining enterprise-level security for users and devices. SASE can help.

SASE combines software-defined wide area networking (SD-WAN) with best-of-breed security capabilities to deliver exceptional user experience and secure cloud access.

SASE flips the security model by deploying services at points of presence (PoPs) near users and systems that need them. These PoPs can dynamically allow or deny access based on network policies set by IT.

Zero Trust Network Access

Zero Trust Network Access (ZTNA) enables mobile users, remote workers, and branch offices to safely access enterprise applications while reducing the risk of lateral movement on the network. With ZTNA, privileged access management (PAM) systems use automation to evaluate requests and automatically approve or deny them.

Secure web gateways (SWG) like those offered by Versa Networks help prevent cyber threats and data breaches by filtering unwanted content from internet traffic, blocking unauthorized user behavior, and enforcing company security policies. SWGs can be deployed anywhere, making them ideal for securing remote workforces.

In addition, SWGs can inspect content to improve visibility and security. Moreover, SWGs can be integrated with various other cloud security services.

Gartner defines a SASE architecture as combining software-defined wide area networking (SD-WAN) capabilities with various network security functions delivered from a single cloud platform. The SASE pillar handles security functions like threat protection, online filtering, sandboxing, and data loss prevention.

Identity-Based Access Control

Security teams can use identity-based access control (IBAC) to provide visibility into who has access to specific resources and applications. This enables organizations to track and monitor user activity across multiple cloud services and platforms, providing insight into potential threats and risks.

IAM systems can also help organizations manage cloud infrastructure entitlements by analyzing the complexity of permissions and determining which unused and over-privileged access rights can be retired. This can help prevent identity-based attacks by reducing the likelihood of compromising users and data.

Identity-based access control is an essential part of a secure cloud infrastructure. It can ensure that user access rules and policies are consistent throughout an organization, even when users move from on-premises to the cloud.

A SASE architecture combines backbone and edge networking functions, like content delivery networks (CDNs), VPN replacement, and WAN optimization, in one service that can be rapidly deployed and scaled as demand grows. It also eliminates the need for enterprises to purchase and manage a complex collection of point solutions.

Secure Web Gateway

A secure web gateway (SWG) is a network security solution that protects organizations from malware, viruses, and suspicious and malicious website traffic. It also protects critical and sensitive data, such as user data, confidential files, and intellectual property.

The SWG enables a company to implement acceptable use policies and enforce them with real-time inspection of web traffic. The SWG also includes URL filtering, SSL inspection, advanced threat defense, and legacy malware protection.

It also detects data loss by examining outgoing traffic for unique patterns associated with sensitive user data, such as credit card information and medical and other sensitive documents. It can also thwart attacks that may exploit unsecured web-based applications to steal data from the organization.

A secure web gateway can be deployed as a standalone cloud-based service or a more comprehensive security solution. It can provide a more flexible security architecture for enterprises adopting cloud-native technologies.

Secure Mobile Access

As cloud applications and IoT devices proliferate, traditional network security solutions can no longer protect them. Instead, they are piling on complexity and costs.

Through a unified security infrastructure, SASE (Security As-a-Service) enables organizations to extend secure access to all cloud and network resources, including mobile apps and remote users. SASE delivers context-aware device authorization, application-level VPN and advanced authentication with single sign-on to provide end-users with simple, fast access to the business applications and data they need while protecting the enterprise from rogue access, malware and phishing attacks.

The SASE platform is scalable and cloud-native, and it is easily deployed and managed as an automated, cloud-delivered service with no technical debt. It leverages the Zscaler Zero Trust Exchange to bring security policy enforcement as close as possible to users, with global coverage across 150+ points of presence.

SonicWall offers FIPS 140-2 certified cryptographic modules for SMA and NetExtender clients to connect to your network from AWS or Microsoft Azure public cloud environments.

Endpoint Security

Endpoint security aims to protect the devices that access a company’s network. These include laptops, desktops, servers and mobile devices.

Cloud-based endpoint protection systems are quick to deploy, easy to manage and scalable. They also have various features to help prevent cyber threats, such as patch and vulnerability management.

Traditional endpoint protection platforms (EPPs) rely on storing a database of threat information locally, which can bloat endpoints and cause maintenance issues. Modern EPPs use the cloud to hold a growing database of threat information, which frees endpoints from this bloat and makes it easier to maintain.

In addition to ensuring the network is protected, EPPs protect business-critical data on endpoints. They do this through IPS technology that analyzes traffic to and from endpoints for signs of malicious activity.

As employees become more mobile, incorporating BYOD policies and remote work into the workplace, the need for security has grown. This requires a security approach that can keep up with the evolution of cyber threats and deliver a consistent security experience across all devices, applications and network connectivity.
