The simple definition A network switch is a networking device that connects devices together on a computer network. It allows multiple devices to communicate with each other by forwarding data packets between them. When a device, such as a computer or a printer, wants to communicate with another device on the network, it sends a data packet to the switch. The switch then examines the packet and forwards it to the appropriate device.
The Simple Definition Imagine being able to access the internet from anywhere in your house without the need for cables and wires. That’s exactly what a wireless access point (WAP) allows you to do. A WAP is a networking device that allows wireless devices such as laptops, smartphones, and tablets to connect to a wired network and access the internet. It works by receiving signals from wireless devices and forwarding them to the wired network, where they can be processed and sent to the internet.
The Simple Definition A WLC is a networking device that acts as a central management system for one or more WAPs. It is responsible for controlling the configuration, security, and performance of the WAPs in the network. A wireless LAN controller (WLC) is like the conductor of an orchestra for your wireless network. It manages and coordinates the different wireless access points (WAPs) in your network, ensuring that they all work together seamlessly and efficiently.
If you are configuring the SMTP setting on Cisco ISE, you may have found an interesting error when complete this configuration —> Connection to smtp.domain.com failed. Could not connect to SMTP Server, SSL Error. Please check the trusted certificates. In this case the issue is that Cisco ISE has to trust the connection with Microsoft 365, since we are doing the connection with MS365 recommended settings as follows:
I’d like to start by saying some wise words I once read somewhere, “Everyone has a plan until they get punched in the mouth” and I believe this one was said by Mike Tyson. I think it holds a lot of true. I recently attempted the AWS Network Specialty exam, and was humbled immediately after seeing the very first 5 questions. I failed the exam and felt a bit down for a while, but to recover from it I want to make sure I work on my plan extensively, so that I don’t get punched that bad next time.
A CMS software like WordPress is awesome because it lets you get statistics in real-time, like page visits, link hits, and many more; in my case, I was unsure what I need to do with a static website and add analytics to it. So I decided to look for ideas quickly. I use Google Analytics in other business websites that I have set up, but those run on Squarespace or WordPress, in this case, my website is hosted in S3, so I was curious
I have noticed this company called Link Tree, where users log in and create a quick Links page with their picture on it and with all their links in one place. These links take them to multiple places, like their Social Media accounts, resumes. Blogs, products they sell, and so on. While I was looking at it, I thought, I can create something like that from scratch. My HTML/CSS Skills are very outdated, so I decided to give it a shot.
As we continue moving forward with our project, we will move to the creation of the certificate using AWS Certificate Manager Requesting Certificate from AWS Certificate Manager I created a quick video to illustrate the process, so it’s easy to follow if you are trying something similar What to look forward to? The next and final piece of the puzzle is to make sure we enable a Content Distribution using CloudFront
Finally we made it to the last step of the project, this will be dedicated to the CloudFront piece Create a Cloud Front Distribution This quick video will show you how to configure the CDN piece with CloudFront. What to look forward to? Perfect, we made it to the end; now we want to make sure our Bucket is only accessible from our CDN, not from the external world. The next post will be the configuration we need to make this happen.
Applying security is important, even when I lab stuff I try to make it as secure as possible, my projects may take a bit more time to complete, but this step will allow me to sleep at night. Applying Security I wanted to make sure that while my bucket in S3 is configured with Public Access, that now that we have Cloud Front up and running, we lock it so that only Cloud Front can access it. Here is a quick video on how to it
