The remote workforce is gaining popularity worldwide, with individuals connecting from any device, from any location, expanding or blurring perimeters. As a result, network security has become more critical for any business.

Due to contemporary security demands and increasing cyber threats, traditional security technologies such as physical firewalls may not provide consistent and effective security. Because of this, companies from all industries need improved and advanced security measurements.

To this, SASE provides companies with data protection and secure remote access with its sophisticated capabilities, it also protects your system regardless of where you work or what device you use. In this article, we will look at 7 essential resources you should learn about SASE.

Best Ways to Learn Essential SASE Resources

1. Zero Trust Network Access — ZTNA

Zero Trust is a security framework requiring all users to be verified, authorized, and continually checked for security specifications and status before being permitted or maintaining access to services and content. “Never trust, always verify” is the core premise underpinning the Zero Trust Security model.

This approach means no device can be trusted by default even if they are connected to a permitted network or even if they were verified before. It aims to gain control over access through user verification. Zero Trust requires verification for both device and user identities, allowing the system to track user behavior.

It also uses the least privileged access to give users and devices only the permission required to execute the operation needed. This limitation protects the network’s confidential sections and evaluates access. SASE framework utilizes ZTNA and with other resources, SASE provides companies security and protection.

2. Cloud Access Security Broker — CASB

The Cloud Access Security Broker, one of the most important components of SASE implementation, functions similarly to a firewall, allowing a company to extend security management beyond its network perimeter. CASBs can be on-premises or cloud-based and it is placed between cloud server consumers and cloud services providers.

CASB has four fundamental principles; Visibility, Compliance, Data Security, and Threat Protection. It uses these four principles to function properly and to provide security. Visibility allows companies to detect anomalous access to un-sanctioned applications within organizations and provide a warning.

Compliance provides companies protection to data stored in the cloud against data breaches, and it also gives companies the power to guarantee that data housed outside the company complies with all regulatory obligations. And with the other two principles, CASB protects your data and prevents you from cyber threats.

3. Software-defined Wide Area Networking — SD-WAN

A Software-defined Wide Area Network is a virtual WAN architecture that allows companies to securely connect users to applications using any mix of transport services, such as MPLS, LTE, and broadband internet services. It is a programmed and automated method of controlling company network connection and circuit expenses.

An SD-WAN utilizes a centralized control function to safely and intelligently route traffic across the WAN to trusted SaaS and IaaS providers. This improves application speed and provides a high-quality user experience, boosting company productivity and agility while lowering IT expenses.

4. Firewall as a Service — FWaaS

Firewall as a Service is a cloud-based firewall solution that helps companies to simplify their IT infrastructure. It includes web filtering, DNS security, advanced threat protection, and an intrusion prevention system as part of its next-generation firewall features. It is positioned between your network and the internet.

The FWaaS solution inspects incoming traffic to detect and address risks, this process examines the information in each data packet’s header, gaining knowledge on where it came from and other behaviors that might indicate it is malicious.

5. Secure Web Gateways — SWB

A Secure Web Gateway is a security solution that keeps untrusted internet traffic out of a company’s internal network. It aims to keep users safe from dangerous online traffic, malware-infected websites, internet-related viruses, and other cyber threats while guaranteeing that the company’s security policy is implemented and followed.

An SWB examines web traffic in real-time, comparing content to the company policies and blocking any information that is unsuitable or violates company policy. It also provides data leak prevention which allows companies to stop their critical data from being leaked or stolen by third parties.

6. Remote Browser Isolation — RBI

Remote Browser Isolation is a security solution that separates the process of accessing websites from the user devices that display webpages. This prevents malware infections and other cyber threats from affecting both user devices and company networks by stopping potentially dangerous website code from running on a user’s device.

It loads webpages and runs any JavaScript code linked with them on a cloud server, far away from user devices and the company’s internal networks. When a user’s browsing session ends, any harmful cookies or downloads linked with the session are deleted as well.

7. Centralized Management

In comparison to traditional site-centric security solutions, SASE delivers a single management platform that manages and enforces security policies for the whole company while simplifying operations. Regardless of their location, central management of security policies simplifies both networking and security elements of remote employees.

Fundamentally, the network perimeter is the location of the endpoint, even if it is on a network that is not under the authority of the company’s workforce. The connected entity’s role determines how security is implemented.
