8 Week Self Study Bootcamp for Security Professionals

| 0 comments

It is important from time to time that we all revisit terminology. For this reason I have put together the following resources in the hopes of learning something new or at the very least bringing back things that we all have learned in years past. In the course of looking for material, I found a number of wonderful lectures from MIT and other various resources. Each of this lectures are licensed under the Creative Commons license. Each week is made up of related categories and there are typically anywhere from one to four topics for review. In the event you … Continue reading

20 Introductory Nmap Command Examples for the Technology Professional

| 0 comments

I’m not going to attempt to cover what Nmap is and what it can do. Rather the author states: Nmap (“Network Mapper”) is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of … Continue reading

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 … Continue reading

WiFi WPA2 Hacking 101

| 0 comments

I want to introduce the idea of breaking WPA2 security by obtaining the password defined by a given network. The reason I am writing about this is both for educational reasons and from the perspective of strengthening security. In many ways I wish I could say that I surprised about just how easy it is cracking a WiFi password, but many people I talk with seem to think that Wi-Fi Protected Access II (WPA2) itself is he gatekeeper. Of course this is not true and just like anything else where a password is involved the password itself is the gatekeeper. … Continue reading

How To Defend Against Cross Site Scripting With Microsoft .NET 4.5 AntiXss

| 0 comments

One of the most common threats to websites is cross site scripting (XSS) which is the idea that a malicious user is attempting to load content into your website. Examples include JavaScript and HTML. This attack is carried out typically via a form input or query string. XSS can result in very nasty results which include content modification or worse hijacking user account information. If you’re asking yourself how you can possibly reduce the likelihood of this threat, the answer is simple. Encode and never trust user input under any circumstance. It is not that all users are attackers, but … Continue reading

Spoof Your MAC Address

| 0 comments

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 … Continue reading

Down In The Weeds With sqlmap

| 0 comments

Here I plan to take a look at sqlmap and the capabilities that it provides in order to identify weakness in security so that this weakness can be addressed before a breach occurs. The tool sqlmap, like many tools, can both be used for good and bad depending upon the role of the individual. I approach this tool as a mechanism to perform penetration testing in order to uncover the vulnerabilities that otherwise may go unnoticed. If you are not sure what sqlmap is the best way I can define this tool is that it is an open source penetration … Continue reading
