Difference between Firewall and Next Generation Firewall

Do you think you require a next-generation firewall (NGFW)? Do you know what distinguishes a traditional firewall from an NGFW? 🤔

I just dropped a new video on my YouTube Channel, and in this video, I will elaborate on the differences between a traditional firewall and an NGFW. Furthermore, I will highlight the shortcomings of the traditional firewall and how the NGFW tackles those issues 😎

What is a Firewall: Why do you need it?

Are you concerned about the security of your network? Are there people trying to breach it, either from the outside or within your organization? These are no longer just fictional scenarios; they can have real and significant consequences for your business, finances, and reputation. How can you protect your network infrastructure from these cyber threats? 🤔

If you find yourself worrying about these questions, you've come to the right place. Fortunately, there are ways to protect your network infrastructure from these threats. One of the most effective tools for network security is a firewall. But if you're not familiar with this technology, it can be difficult to understand how it works and how it can be implemented in your organization 👨‍🏫

What is DHCP Snooping and Dynamic ARP Inspection?

Imagine a scenario where an attacker launches a DDoS (Distributed Denial of Service) attack on your network's Dynamic Host Configuration Protocol (DHCP) infrastructure. At the same time, they poison the Address Resolution Protocol (ARP) entries in your gateway switch, causing significant damage to your entire network. This type of attack could potentially disrupt your network's connectivity, leading to serious consequences such as data loss, service downtime, or even financial losses 🤔

I just dropped a new video on my YouTube Channel, and in this video, you will learn about the effective use of DHCP Snooping and Dynamic ARP Inspection to safeguard your network against DDoS and Man-in-the-Middle (MITM)attacks. The video will guide you through the process of setting up and configuring these security measures, helping you to ensure the safety and reliability of your network infrastructure 😎

What is Port Security and How to Configure it?

If a hacker walks into your office, they take an Ethernet cable and physically plug it into their laptop. Does that mean you are toast? 🤔

Unfortunately, this is a reality for many organizations today. But this doesn't have to be your fate. I just dropped a new video on my YouTube Channel, and in this video, I show you how to protect yourself against physical infrastructure attacks. I provide a high-level overview of Cisco switch port security, and then I jump directly into the configuration details. All Cybersecurity starts with physical security 😎

What is AAA Security?

First, I wish you a happy new year. May God make this your most successful year yet filled with peace and happiness.

Second, as cyber threats continue to evolve, AAA in cybersecurity has become more crucial than ever before. In cybersecurity, AAA stands for Authentication, Authorization, and Accounting. It's a security framework that helps control and track user access to a computer network 🔐

I just dropped a new video on my YouTube Channel, and in this video, I provide a high-level overview of AAA. I then walk you through RADIUS and TACACS+, which are both AAA protocols used for network access control. This is all part of Zero Trust Security Architecture 😎
