Still working on OSCC certification. Currently working on Linux and everything I have learned so far has been information I already know.

Raw Notes

• Linux Basics

• This site looks useful
  • https://linuxize.com/
• /etc/sudoers
  • list of users that have access to use sudo
  • /etc/sudoers.d
    • Is the recommended way to add more configuration data
• sudo -l or sudo -list
  • Will list all the allowed commands when the user uses sudo
• sudo -i
  • logs you into the root user
• id
  • Will show you the current user id, group id, and groups they are in
• On a lot of Linux distros the # symbol in a terminal usually marks an escalated user
  • root@kali:/home/kali# → Escalated user
  • kali@kali:~$ → regular user
• sudo su
  • Also allows us to login to root with our sudo password
  • Just su would require us to know the root password
• Directory vs file permissions in Linux
  • Read Write and Execute are fairly straight forward for files. They are exactly what I think of when I think of permissions however folders operate differently
  • Read Access - Gives the permission to see or list a directories contents.
  • Write Access - Allows the Creation and Deletion of files
  • Execute Access - Gives the ability to go in and traverse threw the directory

• WINDOWS BASICS

  • Windows files are not case sensitive
  • Windows like backslashes over /
  • Windows has Registry instead of etc configs
  • Windows is GUI > CLI
  • Windows has two CLI’s. powershell and cmd
  • CMD
    • help
    • /?
      • shortcut to get information
