Lockdown brings open source firewall to iOS

Lockdown Apps is a new firewall application for iOS. Like Guardian Firewall, which we covered last month, Lockdown uses the iOS VPN framework to intercept all incoming and outgoing network traffic, and allows you to block connections to any address.

Unlike Guardian Firewall, Lockdown works completely on your device. It is also open source.

Why iOS needs a firewall

The Mac has always had a user-configurable firewall, but in iOS the only built-in security tool we have is the Safari content blocker. And that only works for web pages.

Lockdown and Guardian Firewall aim to change that. Lockdown, from the Confirmed developer, includes some preconfigured rules, but it's up to you to add new addresses to the list. Everything you add will be blocked, both on the web and in internal applications. Safari content blockers can block the Facebook website and Facebook cookies, but Lockdown will prevent any application, including Facebook's own applications, from connecting to facebook.com.

The Guardian Firewall application, on the other hand, routes all your Internet data through its own servers and eliminates any unreliable traffic. It also blocks connections that you consider malicious or that compromise your privacy. This approach is less secure, or at least more difficult to secure, because you have to trust the people behind Guardian Firewall with all its data. But it is also much more effective, since you don't have to block anything manually. And the developers behind the service seem reliable in my limited control.

Guardian Firewall developers also decompile and examine applications in the application store to find out what type of data they are stealing / sharing, if any. According to the developers:

This capability allows us to monitor changes in real time as application trackers are added, updated and removed. We can easily find out what types of data are sent to external servers, and that is why every alert in the application is able to describe what we prevent from going out when blocking the connection.

On Lockdown

Lockdown & # 39; s- The device approach is more transparent to you, the user. You can check the source code of the application on Github. And if you have a developer account, you can create it yourself and install it on your devices. (I wonder if there is a way to verify that the version available in the App Store is built from the same source. If you know about this, let me know on Twitter or in the comments of this publication).

However, there are now two legitimate firewall applications for iOS. You will find them in the App Store (Guardian Firewall will be available on July 31). And both use an approved method (VPN) to do their job. I prefer iOS to come with a built-in firewall, but this is a big step in the right direction.
