# Additional Topics

Additional Topics

* Be careful opening unknown documents.
  * Go back to the tools section to help with this.
  * Files, upon being accessed, can execute activity. An example here is that Microsoft Office products can run Macros. Macros are used by bad actors to their advantage for their malicious activity.
* Use your Security Software!
  * Linux: UFW and fail2ban are two common options and are great. Security AV products are also widely supported.
  * Windows: Use your AV and your firewall. Nothing is guaranteed to 100% protect you, but everything helps.
  * Apple: The same context above, applies to Apple.
  * It is a misconception that one OS is more safe or more Secure than another. It is all about opportunity and return of investment for bad actors.
* Use YouTube
  * If you don’t know something, go search YouTube. I am constantly watching and learning something new.
