Install Apache with Homebrew

Install Apache with Homebrew

Installing Apache

# Start by stopping the built-in Apache, if it's running, and prevent it from starting on boot.
# This is one of very few times you'll need to use sudo:
sudo launchctl unload /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/null

# We need to tap homebrew-dupes because "homebrew-apache/httpd22" relies on "homebrew-dupes/zlib"

and install Apache 2.2 with the event MPM, and we'll use Homebrew's OpenSSL library

Learning Computer Security

About This Guide

This is an opinionated guide to learning about computer security (independently of a university or training program), starting with the absolute basics (suitable for someone without any exposure to or knowledge of computer security) and moving into progressively more difficult subject matter.

It seems that most people don't realize how much information is actually available on the internet. People love to share (especially geeks) and everything you need to become well versed in computer security is already available to you (and mostly for free). However, sometimes knowing where to start is the hardest part - which is the problem that this guide is intended to address. Therefore, this guide can accuratley be described as a 'guide to guides', with additional recommendations on effective learning and execises, based on my own experiences.

Many of the free resources are the best resources and this guide focuses on them. It is intended to provided a comprehensive
