APFS Overview – By Tim Standing , OWC

HFS+ (Hierarchical File System Plus), an outgrowth of the original Hierarchical File System that was introduced in 19851. With the roots of the file system now over 30 years old, Apple released a new file system called APFS (Apple File System) that will be shipped on all new Apple devices starting in 2017. As new versions of Apple operating systems roll out later in 2016 — macOS Sierra, iOS 10, tvOS 10 and watchOS 3 — existing devices will use APFS.

With the release of Mojave, Mac OS 10.14, APFS is quickly becoming the default file system for Mac OS. While it brings many new features to Mac OS file systems, it is not without its problems. In this talk we will discuss what features which are introduced to Mac OS with the arrival of APFS. We will discuss how some of these features are implemented and the performance and data security ramifications of these changes, both positive and negative. Lastly, we will cover some of the command line tools which allow access to some of the more advanced features with some examples given.

About Tim Standing
Tim Standing has been writing drivers and storage utilities for Mac OS since 1986.  He is the creator of SoftRAID for Mac OS X and is currently VP of Engineering at OWC Holdings, Inc. In the past year, Tim has added APFS support to SoftRAID as well as two additional RAID levels: RAID 6 and 6+. He has also patented a write acceleration technique which enables the write speed RAID volumes to be as fast as the read speed. Tim’s team is responsible for SoftRAID, SMART Alec and all the drivers and utilities which make OWC products so exceptional.

SaintCON – By James Reynolds, University of Utah, Biology

SaintCON is an annual technology security conference presented by the Utah chapter of the Security Advisory and Incident Network Team (“UtahSAINT”). This conference has been held for 14 years throughout the State of Utah. Prior to 2013 the conference was called the “UtahSAINT Conference”, but was renamed to be more recognizable and could flourish on it’s own.SaintCON is focused on providing great technology security instruction and training. Topics and activities provide all levels of security training from fundamentals to advanced techniques.

James will provide a quick report on some of the highlights including the Hacker’s Challenge game and some of the ideas from a keynote.

About Hacking – Capture the Flag
Hacking – Capture the Flag is an online game designed to teach skills by doing.  Some of the skills involved hacking microcontrollers, cryptography, password cracking, forensics, reverse engineering binaries, reading network packets, hacking servers, and trivia.  For example, here’s probably the easiest one (cryptography).

This simple cipher was a favorite of a certain Roman emperor.  See if you can decode the message below into the correct answer.  You shouldn’t need too much luck to get it right.

Other challenges involve downloading binaries, data files (like network pcap files), and several of the puzzles are just ip’s or url’s without much info on what to do (the ip’s/url’s point to VM’s).  There are hidden “flags” either in the files downloaded or there are hidden instructions on how to get the flag.  The flag is just a short string that is entered into a webpage.  Points are given to each participant and there is a scoreboard.
