We'll have 2 presentation on Thursday, "Intermediate shell scripting: getting more bash for your $" and "SSH and the shell-go forth securely", both from der.hans

 

der.hans: Intermediate shell scripting: getting more bash for your $

Description:
Want to take your shell scripting to the next level? Interested in adding string manipulation and arrays to your arsenal? In shell math?

Shell still has the best system integration for stringing together our favorite command line tools such as ls, grep and sed. Better yet is doing some of that work in the shell without reaching for a forked program, especially inside loops. This presentation will cover intermediate scripting techniques and useful command line tips.

After attending this session, audience members will understand string operators, in shell math, indexed arrays and associative arrays. They will also be familiar with regular expressions, globbing and differences between the two. Finally, attendees will be familiar with useful builtin variables.

der.hans: SSH and the shell-go forth securely

Description:
SSH is the go to tool for sysadmins and developers for interactive connections to remote machines. It creates secure, encrypted connections between computers, even across hostile networks. Unless you accept keys without verification (DON'T DO THAT!!!).

SSH can also create tunnels for encapsulating other connections, including other protocols and data. Sysadmins can bridge protocols across networks for ease of access such as a one-off data sync. Devs can present the dev database on their desktop to ease use of graphical development tools.

After attending this session, audience members will be able to create a local tunnel from client to server, a remote tunnel from server to client, and do simple analysis of local vs remote evaluation of a command. Attendees will be able to use tunnels for SSH or sample other protocols (MySQL and HTTP), and tunneling via a third party system. They will also be familiar with dynamic SOCKS proxies and using SSH to tunnel graphical applications. Finally, attendees will also learn SSH configuration and command line tips for convenience of use, including using forced command to restrict an SSH key to one purpose.

Programming Defensively

Join the Phoenix Linux Users Group at their Security Session to learn about defensive programming. Understand how software is written effectively, what to look for when checking security, and how to verify that you are following good practices. This will not be an introduction to computer programming but will be a discussion of how to write software properly with a focus on security and safety.

* Any discussion of paid services or software will be done for educational purposes only. Neither the instructor, PLUG, or any one involved in this course endorses any paid services or products discussed at this meeting.

Illegal Commerce and The Net

Join the Phoenix Linux Users Group at their Security Session to learn about crypto currencies, online trade, and where data is sold. What does a criminal do after they get your information? This two hour meeting will focus on providing a simplified and easy to follow explanation of the black markets that operate around the world on the internet. Find out about the supposed layers of the internet, how to use tor, and why bitcoin is as important for legitimate trade as it is for criminals.
