7MS #147: DIY Hosted Mutillidae

In this episode I talk about how to build a cheap hosted Mutillidae server to safely hack away on while keeping other Internet prowlers out. Here are the basic commands to run to lock down the Digital Ocean droplet's iptables firewall:

*Flush existing rules*

**sudo iptables -F**

*Allow all concurrent connections*

**sudo iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT**

*Allow specific IPs/hosts to access port 80*

**sudo iptables -A INPUT -p tcp -s F.Q.D.N --dport 80 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT**

*Allow specific IPs/hosts to access port 22*

**sudo iptables -A INPUT -p tcp -s F.Q.D.N --dport 22 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT**

*Block all other traffic:*

**sudo iptables -P INPUT DROP**

*Provide the VPS loopback access:*

**sudo iptables -I INPUT 1 -i lo -j ACCEPT**

*Install iptables-persistent to ensure rules survive a reboot:*

**sudo apt-get install iptables-persistent**

*Start iptables-persistent service*

**sudo service iptables-persistent start**

*If you make iptables changes after this and they don't seem to stick, do this:*

**sudo iptables-save > /etc/iptables/rules.v4**

See this Digital Ocean article for more information.

We've reached the end of this series, and I come into this final chapter bearing good news: I have a job! So in today's episode, I just wanted to kick back and share some cool things I'm working on as I ramp up in this new adventure (and that will also provide good topics for future episodes): Webapp pentest tool bake-off In the next week I'll be evaluating the following for a more general/automatic Webapp scans: Netsparker HP WebInspect Qualys AppSpider SIEM comparison We're looking at several tools to do both on-prem and managed SIEM solutions. If you've got recommendations or experiences to share I would love to hear them - please contact me. Thanks in advance!
