How to Use OpenVAS to Audit the Security of Your Network (1/2)
Synopsis
The Open Vulnerability Assessment System [http://www.openvas.org/index.html]
(OpenVAS), is a Free/Libre [https://www.gnu.org/philosophy/free-sw.html]
software product that can be used to audit the security of an internal corporate
network and find vulnerabilities in a free and automated fashion. It is a
competitor to the well known Nessus vulnerability scanning tool. Analyzing the
results from tools like Nessus or OpenVAS is an excellent first step for an IT
security team working to c

Logging OwnTracks to Logentries
A previous blog

showed how MQTT logs can be sent to Logentries for storage, analysis and how
those logs can be to alert on potential MQTT security threats, as well as to
store and visualize sensor data. This blog follows that by showing how to build
a fully connected IoT system composed of the OwnTracks iOS app as an MQTT
publisher, a Raspberry Pi with Mosquitto embedded as an MQTT messaging broker

Logging Mosquitto Server logs (from Raspberry Pi) to Logentries
The Internet is evolving and part of this is the emerging Internet of Things
(IoT). IoT allows us to use the Internet to seamlessly connect the cyberspace
and real world using physical sensors at huge scale, allowing us to gather and
analyze the data across many domains. It is estimated that there will be 20
billion Things connected to the Internet by 2020, generating an enormous amount
of data.

Cross Site Scripting (XSS) Attacks
[https://www.rapid7.com/fundamentals/cross-site-scripting/] are the second
category of the three largest web attacks used today. Here, we’ll set up a node
server to demonstrate an XSS attack, see browser based XSS prevention, and
finally discuss what further exploits exist based on this attack.
Setup
Here’s our normal, tiny node server to demonstrate XSS.
Create the file server.js as follows:

Moving away from MVC
In of all my years as a software engineer, trying new libraries, frameworks and
paradigms has been such a pleasure especially in web development. Even before
the well known javascript libraries, web development was based on backend apps
which render heavy html code within css and some js code. Frameworks such as
spring, .NET MVC, django and rails helped us with abstractions and predone tasks
increasing development speed and quality (reuse principles). But, it was not

You’re a malware writer. You’ve been tasked with infecting a remote computer,
one that you have never seen before, have no physical contact with, and don’t

computer, or just the name of the facility in which that computer is stored. How
do you proceed?
Hopefully I’m not describing you or someone you know, but sometimes it can be
