How mobile firewalls protect against enterprise threats

<p>Firewalls are an important tool for data protection on traditional desktops and mobile endpoints alike.</p>
<p>A <a href=”https://www.techtarget.com/searchsecurity/definition/firewall”>firewall</a> is firmware or software that can manage the inbound and outbound traffic of a network or device. It provides end-user devices with an added layer of security that contains rules about what traffic can flow in and out.</p>

<p>In homes and businesses, firewalls block unwanted incoming traffic. This traffic could come from hackers attempting to infiltrate the network or take advantage of open ports in an internet-connected device. But as more users rely on mobile devices and connect to public Wi-Fi and networks, mobile firewalls are increasingly important as a first line of <a href=”https://www.techtarget.com/searchsecurity/feature/How-to-fix-the-top-5-cybersecurity-vulnerabilities”>defense against cyberattacks</a>.</p>
<p>Mobile users often run the risk of connecting to insecure networks where hackers are lurking. When a mobile device connects to a compromised network, hackers might be able to capture the device’s incoming or outgoing traffic. Hacking tools also provide cybercriminals with an easy way to execute Wi-Fi attacks. They can pose as legitimate public networks, and when a victim connects to one, all traffic can be routed to the attacker. In turn, the attacker can analyze all the traffic to harvest private data.</p>

<p>A mobile firewall eliminates some attacks that come from the network-based threats that a mobile device is susceptible to. It works like a traditional hardware firewall, but in this case, it’s on a mobile device, which can connect to cellular networks as well as Wi-Fi. Using an application installed on the device, a mobile firewall manages the flow of traffic in and out of a mobile endpoint.</p>
