How Does a Firewall Work?

Android is a mobile operating system developed by Google and released in September 2008. Android has become the most popular mobile OS in the world, with over 2 billion active devices as of February 2019.

Android distribution is fragmented, and devices come with different levels of security and features. The default Android firewall does not protect against attack from the internet. A firewall is a protective device that filters traffic entering or leaving an organization’s network. It can help protect against unauthorized access to data, malware, and other attacks.

A firewall for Android can protect your device from unauthorized access from the internet by blocking incoming connections on ports 80 (http), 443 (https), and 25 (smtp). You can also enable IPsec protection to encrypt traffic between your device and the internet.

What are the Different Types of Firewalls?

There are many different types of firewalls, so it can be hard to know what one is best for your needs. Here is a quick overview of the most common types:

  • Network Firewall: These firewalls protect your computer from unauthorized access over the network, such as when someone breaks into your computer while you’re online.
  • Virtual Private Network (VPN) Firewall: A VPN firewall protects your computer against unauthorized access to your private network, such as when someone steals your credentials and logs in to your office’s Wi-Fi.
  • Application Firewall: An application firewall guards specific applications from accessing sensitive resources, like the internet or other internal applications.
  • Intrusion Detection/Prevention System (IDS/IPS): IDSs and IPSs detect attacks before they happen and block them before they can damage your system.
  • Screen Door: A screen door firewall blocks all traffic except specific ports required for specific applications.
