Title:

Introduction:

This article is about the custom URL blocking feature of Cisco Umbrella, which allows users to dynamically populate the block list with URLs that match specific criteria. This can be useful for blocking access to malicious or unwanted websites, as well as for enforcing company policies on internet usage.

Q: What is Cisco Umbrella?

A: Cisco Umbrella is a cloud-based security platform that provides protection against threats such as malware, phishing, and ransomware. It works by filtering internet traffic at the DNS level, blocking access to known malicious sites and preventing connections to suspicious domains.

Q: What is custom URL blocking in Cisco Umbrella?

A: Custom URL blocking is a feature of Cisco Umbrella that allows users to define their own block list of URLs that match specific criteria. This can be based on factors such as domain name, keyword, or category. When a user attempts to access a blocked URL, they will be redirected to a block page instead.

Q: How is the block list populated?

A: The block list is populated dynamically based on the criteria defined by the user. For example, if the user specifies that any URL containing the keyword “gambling” should be blocked, then any new URLs that match this criteria will be automatically added to the block list.

Q: What are some use cases for custom URL blocking?

A: Custom URL blocking can be used for a variety of purposes, such as blocking access to known malicious sites, preventing employees from accessing inappropriate content, or enforcing company policies on internet usage. For example, a company might use custom URL blocking to prevent employees from accessing social media sites during work hours.

Q: How can I set up custom URL blocking in Cisco Umbrella?

A: To set up custom URL blocking in Cisco Umbrella, users can create a new policy and define the criteria for URLs to be blocked. This can be done using the policy editor in the Umbrella dashboard. Once the policy is created, it can be assigned to specific users or groups within the organization.

As cyber threats continue to evolve, organizations are constantly searching for ways to enhance their security posture. Cisco Umbrella is a cloud-based security platform that helps organizations protect their networks and users from a variety of threats, including malware, phishing, and ransomware. One of the key features of Cisco Umbrella is its ability to block access to malicious or unwanted websites using custom URL blocking.

Custom URL blocking allows organizations to create a list of specific websites that they want to block, either to prevent users from accessing potentially harmful content or to enforce company policies. With Cisco Umbrella, this list can be dynamically populated using a variety of sources, including threat intelligence feeds, internal security logs, and user feedback.

The process of dynamically populating the block list begins with the collection of data from various sources. Threat intelligence feeds provide up-to-date information about known malicious websites, while internal security logs can reveal patterns of behavior that suggest a particular website may be harmful. User feedback can also be valuable, as employees may report websites that they consider to be inappropriate or distracting.

Once this data has been collected, it is analyzed using machine learning algorithms to identify patterns and trends. This analysis helps to identify websites that are likely to be harmful and should be added to the block list. The block list is then updated automatically, ensuring that users are protected from the latest threats.

Custom URL blocking is just one of the many features that Cisco Umbrella offers to help organizations improve their security posture. By dynamically populating the block list, organizations can stay ahead of the latest threats and protect their networks and users from harm.

In conclusion, Cisco Umbrella’s custom URL blocking feature is a powerful tool for organizations looking to enhance their security posture. By dynamically populating the block list using a variety of sources, organizations can stay ahead of the latest threats and protect their networks and users from harm.
