How to exploit a website

| 0 comments

A website is only as secure as those who support the infrastructure. Also you must realize that nothing can ever be 100% secure and all you can really do is look at the risks and implement measures to reduce those risks. Take the time to review the OWASP 2013 Top Ten risks and you will quickly begin to visualize the security landscape, attack vectors, and involvement of personnel. If you are interested in top notch education jump over to PluralSight’s security course titled OWASP Top 10 Web Application Security Risks for ASP.NET. Please stay with me for a moment, but …

Email encryption using OpenPGP and Mailvelope

For those of you looking for an encryption option for your web based email then you should consider the use of these products. OpenPGP.JS is a JavaScript library so therefore the idea is that this library can be used across devices.

Spoof your MAC address

First I want to talk about what the media access control address (MAC) address is before moving into the idea of spoofing a MAC address and the reasons you want to do so. I hope you are familiar with the OSI Model, if not take the time to study the following diagram. Understanding where a MAC address resides in the context of the OSI Model is critical both for real world application as well as industry certifications. I suppose you could always bypass the knowledge and simply spoof you MAC address, but what is the fun in that? Layer two …
