This presentation covers the role of firewalls in network security, detailing types like packet-filtering, stateful inspection, proxy, and next-generation firewalls. It outlines key functions such as traffic monitoring and threat detection, and offers guidance on selecting the right firewall based on network size, security needs, performance, and budget. You'll learn how to choose the best firewall for your organization.

2. In today’s digital landscape, protecting your
computer and web server from viruses and cyber
threats is paramount. Firewalls serve as crucial
defenses by filtering network traffic and
preventing unauthorized access, ensuring data
integrity and security in an increasingly
interconnected world.

3. A firewall is a critical tool that controls traffic from external
sources, such as the internet, to protect against hackers,
viruses, and other malicious networks. It filters incoming data
based on predefined rules to safeguard system functionality and
security. Additionally, firewall systems act as guards for system
entry points, known as ports, ensuring comprehensive
protection against unauthorized access.
What is Firewall?

4. FUNCTIONS OF THE
FIREWALL SYSTEMS :
The firewall protects your website
from the given sources below:
Intrusions: Intrusions are unauthorized users who try to have
access to your computer.
Brute Force Attacks: Those attacks in which the hacker tries
numerous username and password fusions to get to your
credentials.
Malware: It involves stealing your personal information, infecting
your computers, and spreading to other devices too.

5. TYPES OF FIREWALLS
Software and Hardware Firewalls
Software Firewalls: Installed on computers to log activity, block unwanted
applications, and manage user permissions through software applications.
Ideal for individual devices.
Hardware Firewalls: Physical devices placed between the gateway and
network, such as routers. Suited for large-scale protection in business
environments.
Next-Generation Firewalls
Offer advanced features like antivirus protection, application monitoring, deep
packet inspection, and intrusion prevention. Effective at preventing malicious
attacks on systems.
Packet-Filtering Firewalls
Evaluate packets of data against predefined rules when sending emails,
uploading files, or accessing websites.
Less effective as they may allow malicious traffic through if rules are not
properly configured.
