Host-based firewalls are software applications installed on individual devices such as computers or servers. They provide protection at the device level by monitoring and controlling network traffic specific to that device. Host-based firewalls are particularly useful for remote workers or small businesses with a limited number of devices.
C. How Firewalls Work
Firewalls work by analyzing network packets and comparing them against a set of predefined security rules. These rules can be based on various criteria such as source and destination IP addresses, port numbers, protocols, and specific application signatures. If a packet matches a rule, it is either allowed or denied based on the configured policy.
Firewalls can operate in different modes, including:
- Packet Filtering: Examines individual packets and filters them based on predetermined rules.
- Stateful Inspection: Tracks the state of network connections and allows or denies packets based on their relation to established connections.
- Application Layer: Inspects the content of application-layer protocols to provide granular control and protection against specific application-level threats.
Firewalls play a crucial role in protecting small businesses from unauthorized access, malware infections, and other cyber threats.
III. Introduction to VPN
A. What is a VPN?
A virtual private network (VPN) is a technology that provides a secure, encrypted connection over the public internet. It allows users to access a private network remotely and transmit data securely, as if they were directly connected to the network.
B. Benefits of Using VPN
Using a VPN offers several advantages for small businesses, including:
- Secure Remote Access: Employees can securely connect to the company’s network from remote locations, ensuring the confidentiality of data transmitted.
