|Title||Basic Security Threat Modeling Activity|
|Overview||Provides a starting place to access the security of any system on the Internet.|
|Prerequisite Knowledge||Basic Linux Command line knowledge. If you need this knowledge, please complete the Linux Basic Command line activity.|
Learners will gain a basic understanding of how to start to analyze the vulnerabilities in an open source deployment. Learners will be able to explain the purpose of a threat model. Learners will have basic knowledge of several tools that exist to look for vulnerabilities in an open source deployment.
Making an open source deployment secure may seem like a daunting task. Where do you begin to look for vulnerabilities and threats in a system? This activity gives a starting place.
Think about where you live and the surrounding areas around your home. For example, your home has doors and windows. Are they all locked? It may have dark outside areas where someone could hide. If you were looking to break in, what would you do? When you think about making your home safer where you feel more secure, you are creating a threat model.
Building a threat model for an online system is very similar. Computers have places of entry just like a home. Are all the ports closed? Is there any data open and exposed without protection? Do any of your users have weak passwords?
To find out more information about the threat modeling process in general, visit The following website: https://www.owasp.org/index.php/Threat_Risk_Modeling
To help you start to analyze your system, below are three steps to get your started.
1. Network Security: What do others see about my system?
To start analyzing your system, you first need to know the IP address. If it has a domain name you can use that. Start with the Host command and see what you can find out. If you don't know this command, type man host on the command line.
Once you know where the system lives, you can find out many things about the system.
Here are many other tools to deepen your level of understanding about the system.
Dig – a DNS recon tool - http://www.thegeekstuff.com/2012/02/dig-command-examples/ Dirb – a webserver directory enumeration tool - http://tools.kali.org/web-applications/dirb Host – a DNS client - just type man host on any linux command line Nmap – a network scanning tool - type man nmap on any linux command line Telnet – a network service client - type man Telnet on any linux command line Whois – a domain registry client - http://www.computerhope.com/unix/uwhois.htm Wireshark – a packet capture and analysis tool - https://www.wireshark.org WPScan – a wordPress vulnerability scanner - https://www.randomstorm.com/resources/free-tools/wpscan/
2. Password Cracking: A major weakness to any system are the passwords chosen by the people who have access to your system. How secure are the passwords? There are several tools you can use to try and crack your passwords.
3. Writing Secure Code: To make your system less vulnerable, it is important to write code securely. The following workshop provides 2.5 hours of training in writing secure code.
Now that you have a basic overview of some tools that will help you, you can dive deeper into each one. Find and fix your vulnerabilities yourself, before someone else takes advantage of them.
