You will master network monitoring to discover and identify potential hackers, malware and other adversaries that might be lurking on your network. Using tools like Wireshark, Tcpdump and Syslog.

We then move away from network security and onto the details of how we are tracked online by corporations, nation-states your ISP and others. You will understand the techniques used like zombie super cookies, browser fingerprinting and how browser profiling works so third parties can establish who you are online.

We look at search engine privacy - and how to mitigate the tracking and privacy issues of search engines and their associated services.

Browser security - We cover one of the largest risks online, the browser. The doorway into your system. How to best reduce the attack surface of the browser and harden it for maximum security and privacy. A critical consideration for reducing your risk.

Finally you will fully understand how to best use methods of authentication including passwords and multi-factor authentication - soft tokens and hard tokens.

The best password managers to use and why. How passwords are cracked, and how to mitigate the cracking.

This is volume 2 of 4 of your complete guide to cyber security privacy and anonymity.
