💻 I-B-3. Installation Process 3: Root Password Setting: Guide to Setting a Strong Password

 

🛡️ Proxmox VE #Root Password Configuration: The First Step in Server Security

The step following the #disk and #network configuration in the #ProxmoxVE installation process is setting the #Root #password

Since the #Root account holds #supremeadministrative #privileges on a #Linux system, the #strength of this password determines the #core of #server #security

This post provides a #guide to #setting a #strong #password and #security #tips to safely protect your #Proxmox #server

1. Understanding the #Importance of the #Root #Account

A. What is #Root #Privilege

  • #Root is the #highestlevel #administrator account that possesses #all #privileges of the #system in #Linux/#Unix-like operating systems

  • The password set during #ProxmoxVE installation is #used for #webinterface access (#root@pam) as well as #terminal access via #SSH

  • If the password is #leaked, it can lead to #serious #securityincidents such as #VM #deletion, #data #destruction, and #system #setting #changes

B. #Password #Setting #Steps

  • Enter the desired password in the #Password field of the installation wizard, and #re-enter the #identical password in the #Confirm field

2. #Principles for #Setting a #Strong #Password



To defend against #BruteForceAttack and avoid #exposure to #dictionaryattacks, you must set a password that adheres to the following #principles

A. Ensuring #Sufficient #Length

  • Use a #long #password of #atleast #12characters, #recommended #16characters or more, to #maximize the #time required for #cracking

B. Increasing #Complexity

  • The password must use a #combination of #uppercase letters (#A-Z), #lowercase letters (#a-z), #numbers (#0-9), and #specialcharacters (#!@#$%^& etc)\

  • You must #avoid #simple #string #repetitions, #sequential #numbers (#12345), or #keyboard #patterns (#qwerty)

C. #Prohibiting the Use of #PersonalInformation

  • The password #shouldnot include #easily #guessable #information such as your #name, #birthday, #phonenumber, or #frequently #used #words

3. #Additional #Tips for #Security #Enhancement



Here are some #important #tips to #strengthen #server #security even after setting the #Root password

  1. #Block #SSH #Root #Access and #Change #Port:\

    • After #installation, for #security, it is #recommended to #prohibit #direct #Root #access via #SSH and use a #separate #standard #user with #sudo #privileges\

    • #Changing the #default #SSH #port (#22) can reduce the #risk of #automated #attacks

  2. #Activate #WebInterface #2Factor #Authentication:\

    • After accessing the #Proxmox #WebGUI, you must #configure #TOTP based #TwoFactor #Authentication for the #Root account to #double the #security

  3. #Use a #Password #Manager:\

    • #Strong and #complex #passwords are difficult to remember\

    • It is #efficient to use a #passwordmanager #app like #LastPass or #Bitwarden to safely #store and #manage them

  🧠 Maximize VM Performance : Guide to #CPU #Memory Allocation and #AdvancedFeature #Optimization In the previous lecture, we completed the #DiskSettings step of the VM creation wizard. Now, we move to the #CPU and #Memory #Settings step, which #directly determines #VirtualMachine ( #VM ) performance. Beyond simply allocating the #CoreCount and #Capacity , ensuring #Memory #flexibility through the #Ballooning #feature and #physical #hardware #optimization via #NUMA #settings are key technologies for #maximizing #VM performance. This post will guide you through the #specific #methods for #efficiently #distributing #CPU and #Memory in #ProxmoxVE , and #understanding and #applying the #advanced #virtualization #features of #Ballooning and #NUMA #configuration . 1. #CPU #Settings : #Core #Allocation and #Type #Specification #CPU #settings #directly #determine the #processing #capability of the #VM .

💻 Proxmox VE Course III-A-3. Bonding (NIC Teaming) Configuration: Redundancy and Bandwidth Expansion (Active/Backup, LACP)

이미지
  🚀 Extreme #Performance and Non-stop #Stability for Proxmox Networks: Complete Analysis of Bonding Technology In our previous lecture, we covered the basic #network configuration connecting physical NICs to virtual bridges (vmbr) However, a single NIC connection carries inherent risks If a single physical network card fails or a network cable is disconnected, all Virtual Machines (VMs) on that server will be isolated from the outside world, leading to service disruption The powerful #method to eliminate this Single Point of Failure (SPoF) and even expand network bandwidth is 'Bonding' or 'NIC Teaming' In this #lecture , we will take an in-depth look at the principles and #optimization settings of bonding technology, which logically groups two or more physical NICs to achieve both redundancy and bandwidth expansion 1. Basic Concept and Necessity of Bonding Bonding makes multiple physical NICs operate as a single logical interface A. Eliminating Single Point of Fai...
