	- Server Administration
	- Highly configured systems
	- Basic scripting (haproxy vs nginx in front of apache)

- Penetration Tester/Red Teamer

- How (howtoforge.com and https://bitnami.com/stacks and osboxes.org)
	- Build 2 perfect servers a month for 3-4 months

---------------------------------------------------
No a tinkerer

# Log Analysis with Linux command-line tools #
##############################################
- The following command line executables are found in the Mac as well as most Linux Distributions.

cat –  prints the content of a file in the terminal window
grep – searches and filters based on patterns
awk –  can sort each row into fields and display only what is needed
sed –  performs find and replace functions
sort – arranges output in an order
uniq – compares adjacent lines and can report, filter or provide a count of duplicates

# Cisco Logs #
##############
---------------------------Type This-----------------------------------
cd ~/students/yourname/
mkdir security
cd security
mkdir log_analysis
cd log_analysis
wget http://45.63.104.73/cisco.log
-----------------------------------------------------------------------


AWK Basics
----------
- To quickly demonstrate the print feature in awk, we can instruct it to show only the 5th word of each line. Here we will print $5. Only the last 4 lines are being shown for brevity.
---------------------------Type This-----------------------------------
cat cisco.log | awk '{print $5}' | tail -n 4
-----------------------------------------------------------------------



- Looking at a large file would still produce a large amount of output. A more useful thing to do might be to output every entry found in “$5”, group them together, count them, then sort them from the greatest to least number of occurrences. This can be done by piping the output through “sort“, using “uniq -c” to count the like entries, then using “sort -rn” to sort it in reverse order.
---------------------------Type This-----------------------------------
cat cisco.log | awk '{print $5}'| sort | uniq -c | sort -rn
-----------------------------------------------------------------------



- While that’s sort of cool, it is obvious that we have some garbage in our output. Evidently we have a few lines that aren’t conforming to the output we expect to see in $5. We can insert grep to filter the file prior to feeding it to awk. This insures that we are at least looking at lines of text that contain “facility-level-mnemonic”.
---------------------------Type This-----------------------------------
cat cisco.log | grep %[a-zA-Z]*-[0-9]-[a-zA-Z]* | awk '{print $5}' | sort | uniq -c | sort -rn
-----------------------------------------------------------------------




- Now that the output is cleaned up a bit, it is a good time to investigate some of the entries that appear most often. One way to see all occurrences is to use grep.
---------------------------Type This-----------------------------------
cat cisco.log | grep %LINEPROTO-5-UPDOWN:

cat cisco.log | grep %LINEPROTO-5-UPDOWN:| awk '{print $10}' | sort | uniq -c | sort -rn

cat cisco.log | grep %LINEPROTO-5-UPDOWN:| sed 's/,//g' | awk '{print $10}' | sort | uniq -c | sort -rn

cat cisco.log | grep %LINEPROTO-5-UPDOWN:| sed 's/,//g' | awk '{print $10 " changed to " $14}' | sort | uniq -c | sort -rn

Note: On windows you won't need to use the word "sudo" in front of the command below:

---------------------------On Linux or Mac OS X type This-----------------------------------
sudo nmap -sP 157.166.226.*
--------------------------------------------------------------------------------------------



    -if -SP yields no results try:
Note: On windows you won't need to use the word "sudo" in front of the command below:
---------------------------On Linux or Mac OS X type This-----------------------------------
sudo nmap -sL 157.166.226.*

    -Look for hostnames:
Note: On windows you won't need to use the word "sudo" in front of the command below:
---------------------------On Linux or Mac OS X type This-----------------------------------
sudo nmap -sL 157.166.226.* | grep cnn

---------------------------or on Windows type:---------------------------------------------
c:\nmap -sP 157.166.226.* | findstr "cnn"

-------------------------------------------------------------------------------------------



- Port Scan
What's where?
------------
Note: On windows you won't need to use the word "sudo" in front of the command below:
---------------------------On Linux or Mac OS X type This-----------------------------------
sudo nmap -sS 162.243.126.247

---------------------------or on Windows type:----------------------------------------------
c:\nmap -sS 162.243.126.247

--------------------------------------------------------------------------------------------



- Bannergrab/Version Query
What versions of software are running
-------------------------------------
Note: On windows you won't need to use the word "sudo" in front of the command below:
---------------------------On Linux or Mac OS X type This-----------------------------------
sudo nmap -sV 45.63.104.73

---------------------------or on Windows type:---------------------------------------------
c:\nmap -sV 45.63.104.73

Let's dig into this a little bit more:
-------------------------------------
Note: On windows you won't need to use the word "sudo" in front of the command below:
---------------------------On Linux or Mac OS X type This-----------------------------------
sudo nmap -sV --script=http-headers 45.63.104.73 -p 80,443

---------------------------or on Windows type:---------------------------------------------
c:\nmap -sV --script=http-headers 45.63.104.73 -p 80,443

Network Penetration Testing Process (known vulnerabilities)
-----------------------------------------------------------


1. Ping Sweep:
The purpose of this step is to identify live hosts

    nmap -sP <ip-address/ip-range>


2. Port Scan
Identify running services. We use the running services to map the network topology.

    nmap -sS <ip-address/ip-range>


3. Bannergrab
Identify the version of version of software running on each port

    nmap -sV <ip-address/ip-range>



4. Vulnerability Research
Use the software version number to research and determine if it is out of date (vulnerable).

Task Option 1: Basic Shell Scripting
------------------------------------
Watch and do all of the exercises in the video https://www.youtube.com/watch?v=_n5ZegzieSQ
Create a word document that contains the screenshots of the tasks performed in this video
Name the word document 'YourFirstName-YourLastName-LinuxDay1-ShellScripting.docx' (ex: 'Joseph-McCray-LinuxDay2-ShellScripting.docx'). This video instructs you to use a tool called 'whatweb'. I prefer that you use 'dirb' instead.
The example syntax is 'dirb http://45.63.104.73/'
