Firewalls and VPN: What Are They?
Firewalls: The Basics
Firewalls have been around for decades and are a fundamental part of online security. In simple terms, a firewall acts as a barrier between your computer and the internet. It analyzes the traffic between your computer and the internet, allowing legitimate traffic to pass through while blocking unauthorized traffic.
Firewalls can be hardware or software-based. Hardware firewalls are typically found in corporate environments, while software firewalls are commonly used by individuals to protect their home networks.
Software firewalls can be installed on your computer or router, and they come with a range of features, such as packet filtering, intrusion detection, and content filtering.
VPN: The Basics
A Virtual Private Network (VPN) is a private network that extends across a public network, like the internet. When you connect to a VPN, your online activity is encrypted, and your IP address is masked, making it difficult for anyone to track your online activity.
VPNs are commonly used for online privacy, remote access, and bypassing internet censorship. They are available in both free and paid versions, and you can download and install them on your computer or mobile device.
