The Safest Conversation You'll Have This Holiday



  • Do your friends and family rope you into providing tech support when you:undefined:’:undefined:re home for the holidays? Use this opportunity to be a digital security hero and rescue your family from tracking cookies, unencrypted disks, insecure chats, and recycled passwords.

Encourage friends and family members to walk through new security concepts and tools with you, andavoid the pitfalls of taking over their devices and doing it yourself.

    Keep in mind that security concepts and tools like these might be completely new to your friends and family.

There:undefined:’:undefined:s always next Thanksgiving!

  • Make ISO from DVD

    In this case I had an OS install disk which was required to be on a virtual node with no optical drive, so I needed to transfer an image to the server to create a VM

    Find out which device the DVD is:

    lsblk

    Output:

    NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 465.8G 0 disk ├─sda1 8:1 0 1G 0 part /boot └─sda2 8:2 0 464.8G 0 part ├─centos-root 253:0 0 50G 0 lvm / ├─centos-swap 253:1 0 11.8G 0 lvm [SWAP] └─centos-home 253:2 0 403G 0 lvm /home sdb 8:16 1 14.5G 0 disk /mnt sr0 11:0 1 4.1G 0 rom /run/media/rick/CCSA_X64FRE_EN-US_DV5

    Therefore /dev/sr0 is the location , or disk to be made into an ISO

    I prefer simplicity, and sometimes deal with the fallout after the fact, however Ive repeated this countless times with success.

    dd if=/dev/sr0 of=win10.iso

    Where if=Input file and of=output file

    I chill out and do something else while the image is being copied/created, and the final output:

    8555456+0 records in 8555456+0 records out 4380393472 bytes (4.4 GB) copied, 331.937 s, 13.2 MB/s

    Fin!
