  • Setting Calendar Info for Centos 7 VM

    I’ve been learning about cron jobs but when it was time to get my hands dirty, I discovered that the time for my VM was way off! What to do? I found this site, which helped quite a bit. Here’s what I did: And with that, the system was updated.

  • Connecting VM Centos 7 to internet

    I have a Centos 7 virtual machine on my virtualbox hypervisor, which has been great for practicing vim and such. However, when trying to get onto the internet, I wasn’t successful- and poking around the configuration settings of the software platform didn’t seem to work (without doing a deep dive, anyways). I followed this video,…

  • SAN Implementation

    In my previous post, I talked about what a SAN is and how it can be used- now, in this post, I’m going to share my hands-on experience configuring one. There are three SAN components: host, storage, SAN fabric (cables, networking hardware). All SAN storage devices are called targets, while the initiators are the servers…

  • Storage Area Networks (SAN)-background

    Data centers have the infrastructure to hold, and support, vast numbers of servers, ensuring connectivity, redundancy, and protective factors such as temperature control, fire safety, and physical safety. There are three layers: the access layer/edge layer (closest to the machines themselves), distribution layer (switches connecting those access layer switches), and finally the motherlode of them…

  • Hardening Windows: Kerberos

    There are a number of network hardening solutions, including network authentication. This is the process of authenticating the identity provided, to ensure proper access to network resources. There are several approaches: the challenge-response/three-way-handshake, which uses a shared secret, OAuth (an internet, token-based authentication system), OpenID (open source, third party service allows non-related sites access to…

  • Windows: Creating Global Group (AD)

    In the last post, I created a group within a local OU, and this time I’m going to be creating a global group. This is still working on the Windows Server VM Here I have created a group, and you can see how I selected Global Group scope option: Great! Now I add users to…

  • Windows: Creating a Group

    In this exercise, I accessed a VM and within the Active Directory, created a ‘Managers’ group within a OU container (‘Users’). I have to say it’s a little strange working in a GUI like this after spending so much time on a command line interface! Now, time to fill out this newly-created Managers group with…

  • Windows: Managing User Accounts (Active Directory)

    In my previous post, I created a user within an OU, and now I’m going to practice managing user accounts. Brace yourself, the fun is about to begin! 🙂 Similar to before, I accessed the virtual machine Windows Server > Tools > AD Users and Computers. First, I practiced unlocking a user account. Next, I…

  • Windows: Creating User Accounts

    In my security class, I am learning much more about the Windows security environment, and that including creating user accounts. Here are some of what I learned from my hands-on practice to put into play what I learned. Here I’m working on a Windows Server Virtual Machine: Next, I select Tools > Active Directory Users…
