Avoid Data Leak: Effective Ways to Create an ‘Internet Kill Switch’ on Windows

In this hyper-connected digital era, cybersecurity is no longer an option, but a necessity. ‘Internet Kill Switch’ is becoming one of the most important tools in our security arsenal.

In an increasingly connected world, internet security is becoming inseparable from everyday life. With cyber threats constantly evolving, protecting personal data and online activities is not only a necessity but also the responsibility of all of us. Internet Kill Switch’ is emerging as a promising solution for maintaining our digital security.

‘Internet Kill Switch’ is a security feature designed to automatically disconnect your internet connection when an intrusion is detected in your virtual private network (VPN). It aims to prevent data leakage and ensure that your personal information is not exposed to the public internet without adequate protection. With ‘Internet Kill Switch’, you can explore the virtual world with peace of mind, knowing that your privacy is protected even in unexpected conditions.

Bardimin will go into detail about the importance of ‘Internet Kill Switch’, how it works, and how you can implement it in the Windows operating system to improve your cybersecurity.

Why is ‘Internet Kill Switch’ Important?

In this increasingly connected world, cyberattacks are becoming a real threat that lurks every internet user. Online privacy and security are two aspects that cannot be separated from internet use.

‘Internet Kill Switch’ is an essential defensive defense mechanism that protects us from the consequences of attacks by automatically disconnecting your internet connection when the VPN disconnects, preventing leakage of your data.

Cyberattack Protection

When the VPN connection drops, the ‘Internet Kill Switch’ will cut off your internet connection instantly. This prevents cyberattacks that can occur within a window of vulnerability when the VPN is down, such as:

• Data Interception: Without a VPN, the data you send and receive can be intercepted by third parties.
• Man-in-the-Middle Attacks: This attack occurs when an attacker infiltrates a communication between two parties to steal or manipulate data.

Safeguarding Privacy and Personal Data

‘Internet Kill Switch’ also plays an important role in safeguarding your privacy and personal data from unauthorized access, such as:

• Online Tracking: By cutting off the internet connection, the ‘Kill Switch’ prevents online tracking by advertisers or websites that want to learn your browsing habits.
• Information Leakage: Prevents unauthorized parties from sharing personal information such as your location, identity, and online activities.

Steps to Create an ‘Internet Kill Switch’ in Windows

Securing your internet connection with ‘Internet Kill Switch’ is an important step to protect your privacy. Here are the steps you need to follow to set up the ‘Kill Switch’ in Windows.

$adapterName = (Get-VpnConnection -Name $vpnName).ConnectionStatus
if ($adapterName -eq “Disconnected”) {
    Disable-NetAdapter -Name “Ethernet” -Confirm:$false
}

3. Save the script with the .ps1 extension to run it later.

How to Set Windows Firewall to Enable ‘Kill Switch’

To set up a Windows firewall:

1. Go to Control Panel and navigate to System and Security > Windows Defender Firewall.
2. Select Advanced settings and click Outbound Rules in the left pane.
3. Click New Rule… and select Program.
4. Select This program path: and enter the path of the app you want to block.
5. Select Block the connection and provide a name and description for the rule.
