🛡️ Windows Security Firewall and Network Protection for Public Network

When you connect your laptop or PC to a *public Wi-Fi network* (like in a coffee shop, airport, hotel, or library), your device becomes more vulnerable to cyber threats such as *unauthorized access, malware attacks, and data theft**. To safeguard your system, Windows provides a built-in **Firewall and Network Protection* feature under **Windows Security**.

#### 🔹 What is Windows Firewall?

The *Windows Firewall* acts as a protective barrier between your computer and the internet. It monitors incoming and outgoing traffic, blocking suspicious connections and allowing safe communication.

#### 🔹 Why Public Network Protection is Important

Public networks are *unsecured* and can be exploited by hackers.
Cybercriminals may try to *steal personal data* like passwords or financial information.
A firewall ensures only *trusted apps and services* can access your device.

#### 🔹 How to Enable Firewall for Public Network

1. Open *Windows Security* from the Start Menu.
2. Go to **Firewall & Network Protection**.
3. Select **Public Network**.
4. Make sure the *Microsoft Defender Firewall* toggle is **turned ON**.

#### 🔹 Features & Options

**Allow an app through firewall**: Manage which apps are permitted.
**Advanced settings**: Configure inbound/outbound rules.
**Restore defaults**: Reset firewall settings if misconfigured.

#### 🔹 Best Practices for Public Networks

1. Keep *Firewall ON* at all times.
2. Avoid accessing sensitive accounts (banking, payments) on public Wi-Fi.
3. Use a *VPN* for extra encryption.
4. Keep Windows and security updates installed.
5. Disable file sharing when on public networks.

#### ✅ Benefits of Using Firewall in Public Network

Protects your *personal data* from hackers.
Prevents unauthorized **remote access**.
Adds an extra layer of *network security* beyond antivirus.
Gives you control over what apps/services can connect.

🔔 Stay safe online with *Windows Security Firewall & Network Protection* — your first line of defense on **public Wi-Fi networks**.
