What is URL filtering in Palo Alto?

There has been a lot of attention lately towards the new URL filtering in Palo Alto.

The new URL filtering has been brought in as part of our network security strategy to better protect our users. The goal of the new filtering is to stop the ability for malware, phishing, and spam from using Palo Alto to access their content and harm users.

What is URL filtering? URL filtering (aka URL blocking) is a security feature available on most browsers. It prevents access to malicious web sites and helps prevent malware and phishing.

What makes URL filtering so effective? The biggest benefit to URL filtering is that it does not require any user input or action. When you go to a website, your browser automatically checks if the website you are accessing is trusted by the user. If the URL filtering feature is enabled, your browser will block any URLs that are not deemed to be safe.

What does URL filtering block? In Palo Alto, we block access to websites that are determined to be malicious or phishing sites. Malware and phishing websites are typically sites that try to steal your data, such as email addresses or credit card numbers. While we can't predict what sites will be malicious or phishing, we use industry best practices to determine which sites are harmful. In addition, we block URLs that contain any known exploits, such as SQL injection or Cross-site scripting.

What happens when a URL is blocked? You may be wondering, what happens when a URL is blocked? We give you the option to keep the blocked site from appearing in your history. You can also disable the URL filtering for that site to allow it to show up again. If you keep the blocked site from appearing in your history, it will not be available in the future.

How can I stop a URL from showing up in my history? Most browsers have an option to hide blocked sites from the history. To do this, go to your browser's settings and find the option to "Manage search engines" or "Manage search providers". Under that setting, you will see a list of all the search engines or search providers that you've configured. In Palo Alto, you can click the "block URLs" link for each provider to block a URL from appearing in the search results.

Do I need to update any other browsers? Yes.

How do I change the URL filter in Palo Alto?

In Palo Alto I am using the URL filter to control how my app loads up.

My server is set up with a different base URL than when I access the app directly, but the browser will load the app just fine in spite of this fact. I have set the filter in the code to ignore all URLs that do not match a specific string and that does fix it. The problem I'm facing is that, in some browsers, for the first time the URL filter gets loaded I don't get a page at all because of that URL doesn't match anything in the filter.

How do I make the first URL that my app loads be the one that has the URL filter in place? Can I create a new URL that isn't handled by the filter but instead acts as a 'gateway' to a server that does need to go through the filter? I ended up solving this by building a new filter that matched those pages that should not go through the existing URL filter and then I created a new "URL Filter" that acted as a "gateway" to the real URL filter. It uses the old URL filter and then replaces the original in the onComplete() callback function.

What is the priority for URL filtering Palo Alto?

There are two URL filters that get a large amount of attention.

The first is an attack filter. It is used to detect attacks against the network and prevent them from reaching the Internet. This includes attacks like denial-of-service, buffer overflow, and cross-site scripting. The other type of filter is a bot filter. It detects bots and attempts to block them from accessing the web server.

I would put attack filtering as #1 priority and bot filtering as #2 priority. These two filters are required for the web server to function properly. Neither of them have a high percentage of false positives, so if you have a choice between a false positive one filter or a false negative on the other filter, go for the bot filter. Also, if you have the option of blocking some IP addresses, then blocking bot IP addresses is better than blocking random IP addresses. The reason is that bot IPs are more likely to be malicious and need to be blocked. Random IPs are just a general protection against attacks.

If you have some time, you might also want to read the source code for these filters to see how they work. Both of them are very simple, but that doesn't mean they're not effective.

What is URL filtering?

URL filtering is the use of filters or other techniques to reduce the risk of malware, phishing and spyware from accessing your network.

They are an important part of an advanced cybersecurity strategy.

A URL is the main name for a page on the Internet. The most common URL's for a website are: www.domain.com

Www.com/home.php

Www.com/page.id=1234

There are many other types of URL that can be used, like those used in mobile phone apps. What is Malware and How does it get into my Network? Malware is a name used to describe any kind of unwanted software program that has been designed to damage computer systems or to steal private information. If you allow people to connect to your computer via the Internet then it is likely they will have to share a part of their connection with others and that is where they will be exposed to malware. Many of these will be harmless programs but some are designed to damage computer systems. The more advanced ones even seek to steal personal data.

How does it get through my firewall? This is a difficult question to answer and involves some technology knowledge which is not explained here. We have covered this in more detail in The Basics of Firewall Technologies.

The simplest way of thinking about this is that malware is a form of unwanted software that doesn't want to run on your computer. It therefore has to bypass security software to get onto your computer.

These filters all need a way of identifying the different types of software that are trying to access your computer. Each of the different types will be protected by a firewall. If the software is not identified as being part of a legitimate application then it will not be allowed to run and will be blocked.

What is Phishing? Phishing is the illegal process of stealing information from a computer user. It relies on tricks designed to get users to disclose personal information such as usernames, passwords, credit card details and other valuable data.

Phishing has been a problem since the first email was sent and many examples are still available online. It is still used by cybercriminals today.
