How to evaluate and operate a cloud access security broker? CASBs work by ensuring that network traffic between on-premises devices and the cloud provider complies with an organization’s security policies. This article will discuss the job of a cloud access security broker.
What is a Cloud Access Security Broker?
The cloud access security broker (CASB) is a type of security hardware that sits between the user and the cloud application.
It checks for malicious activity, like a keylogger, before you can access the cloud application. A CASB can also be to identify suspicious activity and provide an alert to the user.
A CASB may also be to as an OAuth proxy, as it is to monitor the user’s interactions with a cloud application without exposing the user or the cloud application to security threats.
What Does a Cloud Access Security Broker Do?
What does a cloud access security broker do? The CASB is responsible for enforcing an organization’s security policies, which may include:
Ensuring that users only access cloud applications through the CASB will ensure that all traffic is monitored.
Limit cloud application users to connecting from a specific set of approved IP addresses. Ensure that all users have to authenticate themselves with strong credentials before accessing the cloud application
As previously mentioned, the main job of a CASB is to ensure network traffic between on-premises devices. Also, the cloud provider complies with an organization’s security policies.
CASBs can also be to manage access to cloud applications.
What Are the Advantages of a Cloud Access Security Broker?
CASBs greatly enhance an organization’s security posture by providing a layer of security between on-premises devices and cloud applications.
The following are the main benefits of using a CASB:
Dictate which users can access what cloud applications. Also, which features they can access within the cloud application.
CASB offers a unified approach to securing all cloud apps, whereas multifactor authentication, firewalls, and other layers are to secure cloud apps.
The CASB can be to alert users when they try to access a cloud application from an unauthorized location.
It is like when a user is on vacation and tries to access their work email from a hotel. Protects cloud applications from malware and phishing attacks.
An additional layer of security that protects against man-in-the-middle attacks. The CASB will ensure that certificates are valid, communications are encrypted and that communication is happening over a secure network.
How To Evaluate And Operate A Cloud Access Security Broker?
Evaluating a cloud access security broker is similar to evaluating any other security product.
The following areas should be:
CASB vendors may also offer services to help with the implementation of their product, so evaluate whether such services are available and how comprehensive they are.
In addition, since CASBs are hardware devices, how easy is it to deploy? Some vendors provide virtual appliances that can be on-premises to ease deployment.
Cloud access security brokers have the potential to revolutionize cloud security by providing a unified approach to securing all cloud apps.
