Microsoft provides a workaround for admins who haven't installed KB5023705 and need a temporary fix. This requires them to re-add the accidentally removed UUP MIME types manually using PowerShell commands. The missing file extensions can also be added back to impacted servers with the help of using the Internet Information Services (IIS) Manager by creating new MIME Types with the ".wim" (application/x-ms-wim) and ".msu" (application/octet-stream) extensions.

Installing Windows Server 2022 (evaltuation at this point) on a remote KVM host for the first time. I used this guide as a starting point: https://lnkd.in/gkrN9FF8 As for giving it full control of the second NIC, I left it unconfigured on the host OS, then before the installation click "add hardware" and add a PCI host device. Pick the NIC from the list of detected PCI devices on the host and away you go. I also like to add a second SATA CD device and load the Redhat virtio storage driver iso in there before starting the install. I gave it 100gb disk (I know it's a lot), 16 cores, and 8gb of RAM so it's beefy.

Finding the administrator password of a server running IIS 8.5 if port 21 is open. Also has a SMB vulnerability too. Really interesting. https://lnkd.in/e5g-nj9E

SSH authentication can be via password or using key pairs. Key pair authentication is by far, more secure than password based authentication. This post will walk you through generating a key pair and using that key pair to remotely access another server.

There are varieties of ways to safeguard the server. One method is to change the default port of ssh from 22 to something else. Because the servers are remote and can be accessed from anywhere, changing the port will add another layer of security because attackers will have to figure out which ports to use before brute forcing the server. Here's a little demonstration. Ubuntu 23.04 is installed on my server. As my new ssh port, I've used 32000 ports. You may utilise any of the remaining unused ports. 𝚜𝚞𝚍𝚘 𝚖𝚔𝚍𝚒𝚛 -𝚙 /𝚎𝚝𝚌/𝚜𝚢𝚜𝚝𝚎𝚖𝚍/𝚜𝚢𝚜𝚝𝚎𝚖/𝚜𝚜𝚑.𝚜𝚘𝚌𝚔𝚎𝚝.𝚍 𝚜𝚞𝚍𝚘 𝚟𝚒𝚖 /𝚎𝚝𝚌/𝚜𝚢𝚜𝚝𝚎𝚖𝚍/𝚜𝚢𝚜𝚝𝚎𝚖/𝚜𝚜𝚑.𝚜𝚘𝚌𝚔𝚎𝚝.𝚍/𝚕𝚒𝚜𝚝𝚎𝚗.𝚌𝚘𝚗𝚏 Content of 𝙡𝙞𝙨𝙩𝙚𝙣.𝙘𝙤𝙣𝙛 will go like this, where 32000 is new port.
