Windows Server 2019 Essential Training by Scott M Burrell (Part 1) - Getting Started

The course is in 6 sections, so I'll separate them by parts. I do have Windows Server experience, and 2019 is new to me, though the general idea is the same. The first relevant video opens with " I was speaking recently with a network administrator for a global company. He told me that his IT infrastructure was out of date because his Windows Servers were a version or two behind the newest thing from Microsoft." Just because you can upgrade doesn't mean you should! If your stuff works (well), it works. If new features help your business, or have the possibility for your business to 'grow' into them then sure, upgrade. But there's no need to keep up with the Jones or Gates.

Windows Server Essentials Training Part 4 - Identity and Access Roles

The course is in 6 sections, so I'll separate them by parts. I do have Windows Server experience, and 2019 is new to me, though the general idea is the same. 👋🏾AD Certificate Services can be used to verify user identity and encrypt data with certificates 👋🏾 Install the role on a member server to make it easier. The root Certificate Authority is the most important. 👋🏾 You can make your own certificates with your PKI (private key infrastructure) 👋🏾 The subject name is how someone will be recognized, and for more security, you can specify who can enroll. Can they request certificates, or automatically receive them? 👋🏾 AD Federation Services form trusts across organizational lines to claim the identity of someone in your network as someone who can get resources and permissions. Sort of like the guest accounts in your AD in Azure. 👋🏾 Rights Management Services secures content within files, and even emails. REMINDS ME OF ... Azure Information Protection. 👋🏾 👋🏾

Windows Server 2019 Essential Training Part 3 - Windows Server Enviroments

The course is in 6 sections, so I'll separate them by parts. I do have Windows Server experience, and 2019 is new to me, though the general idea is the same. ✅  Active Directory Domain Services Schema (ADDSS) defines type of objects stored, properties maintained, and how these different bits of data relate to each other. ✅ Active Directory sites/domain/forests have names that aren't an option to change in configuration. In the Sites and Services name, you should change it (Right click it). Name it depending on geographic location. ✅ Link Values are set based on speed or bandwidth. Now we get into path costs and hops, and that's what I was trained in. ✅ Encryption of traffic between VMs on a per-subnet basis! Use Certificates on Hyper-V hosts. Everyone gets a matching certificate Virtual machines/switches are created and managed by network controller. Reminds me somewhat of CHAP and PAP . ✅ Cluster Sets have consistent hardware and shared namespace. They help with high a

Deloitte / InsideSherpa Tech Consulting Virtual Internship

Did you know? Before Covid-19, employers were rather stingy on helping graduates, new or not so new, with internships, often having a very limited time frame that they cared about you. Not so with Deloitte and InsideSherpa ! Check it out here . It was free, and a project to talk about, so I did it. Turns out that consulting is pretty cool. I've enjoyed thinking about the best solutions to bring a business to the cloud, or online.    It's not all just 'Set up a Cloud account and have at it'. My Azure certification gave me a leg up on one of the projects; I was more minute than they expected at points. It did show me that I can do remote work; Work is often already an invasion on someone's life and time. Being able to take my time and work when I wanted to without being burned out was a nice perk. If you still have your school e-mail address, you can sign up with that. I haven't tried it with a business address. This is basically "What does Deloitte do?"

Connecting IoT Devices to a Registration Server (Packet Tracer, Cisco)

In Packet Tracer, a demo software made by Cisco Systems. It certainly has changed a lot since 2016. It's almost an Olympic feat to even get started with it now, but it does look snazzy. This is for the new CCNA, that integrates, among other things, IoT and Automation, which I've worked on here before. Instructions here . I don't know if this is an aspect of "Let's make sure people are paying attention and not simply following blindly", or an oversight - The instructions indicate a Meraki Server, when a regular one is the working option here. I have to enable the IoT service on this server. Also, we assign the server an IPv4 address from a DHCP pool instead of giving it a static one. For something that handles our IoT business, perhaps that's safer; Getting a new IPv4 address every week or so is a minimal step against an intruder, but it is a step. There are no devices associated with this new server; In an earlier lab (not shown), I attached them to 'H

Getting Started with Ansible- Programming and Playbooks - (by NetworkChuck and Jesse Keating)

* I am using an Ubuntu server, which means I could skip epel-release and simply install Ansible from these instructions. Opening the configuration file in vi (as su, or you won't be able to overwrite), I'm pleasantly surprised it didn't take me more than 3 minutes to find #host_key_checking = False . The # means 'this is a comment', so let's take that away so it can work with the demo. Let's configure; This is openly available information over here . Let's ping it; Yes, apparently my Ansible was using older Python for backwards compatibility. But we did successfully ping the router! First bit of automation = ✅ With a bit of manipulation, we can run some good old Cisco IOS commands like 'show ip int brief'; The command is sudo ansible router -m ios_command -a "commands='show ip int brief'" I revisited this the next day and added the second router; I got a really funky error pointing out a

Learn From Home: Jira Essentials (ft. Hogwarts School)

Jira is a piece of project managing software that can be maintained on-prem on a server, or in the cloud (also, technically, on a server). It's a busy piece of planning software for software development, with various modes (scrum and kanban) depending on your project. You can learn the essentials remotely, with a 6-hour course - This is more of a brief, technical overview about using a Kanban board in Jira. Introduction aside, let's get into the completely fake idea of "Installing Wi-Fi At Hogwarts School of Witchcraft and Wizardry", and see how these boards can help keep me on track. Edited to add: This blog and the author supports trans women. This was posted before she decided to act that way online. That's not software! Don't think too deeply about the logistics of magic and technology.

[Webinar] Live Resume Workshop for Cybersecurity Professionals by Katia Dean

Are you struggling to break into the Cybersecurity field? Your resume may be to blame. Also the general mindset that Cybersecurity is an exclusive field that's gatekeep'd to hell and back . So, Katia Dean, Voice of Cyberpros @ Katia's Cylife , gave us a great webinar about how to make a Cyber-esume that catches the eye. It's 2020: People discriminate based on location. Do not put your home address anywhere. If your position is current, put your action verbs in the future. Spell out your acronyms! "CCNA (Cisco Certified Network Associate)". A very interesting point was not needing to put the cities where you went to school at. Schooling doesn't quite matter, and everyone is realizing that (for better or worse). Title yourself for the position you want. There were a variety of resumes, from those making the jump from networking, to those shifting to another position, to the resumes of Doctors of Cybersecurity! Also, a big shout out to Amy Scit

How to Cope With Anxiety

If any employer is reading this and immediately hit 'X' because they think 'anxiety is weakness', good riddance.
