Cyber Security - Python and Web Applications

An introductory look at what is covered in section 2

We explore what is meant by cyber security in the modern world and what actually comprises the work of a cyber security professional.

We will review the methodology of cyber security professionals.

In this brief text summary we will talk about Python and the crash course that's available as a bonus in section 7

An overview of repl.it and how to use Python with this great, free tool

Penetration Testing is a key practice for cyber security professionals. Here we go over the basics of what it is and the variables involved.

As the number of Internet-connected devices continue to grow, botnets are a dominant cause for concern in today's cyber security and information technology landscape. This is an overview of what they are and how they work, including an explanation of DDoS attacks.

We explore the topic of antivirus evasion and how an application can bypass an antivirus scan.

We take a look at the various non-technical ways in which attackers can get sensitive information and compromise information systems.

An introductory look at the content covered in section 3

A brief look at the content covered in section 4

Applications that use vulnerable components can often be the target of devastating breaches. It is important to understand the underlying issues with not keeping dependencies up to date.

A look at how using vulnerable components in Rails might happen and how to avoid and/or remediate it.

An example of how this vulnerability can look in a PHP app and how to remediate it.

A vulnerability that is often overlooked but one that can make a huge difference is not having enough logging and monitoring.

This is an explanation of why logging and monitoring are important.

We look at an example of insufficient logging and monitoring and how to remediate this vulnerability in Rails.

What does it look like when the "Insufficient Logging and Monitoring" vulnerability shows up in a PHP application? We take a look at that here.

We take a look at a popular web security analysis tool for Rails - Brakeman Security Scanner.
