Kenna Security: Connectors and REST API

In the last post about Kenna Security cloud service I mentioned their main features for analyzing data from different vulnerability scanners. Now let’s see how to import Tenable Nessus scan results in Kenna. Here you can see the list of connectors for all supported products:

Kenna connectors

Three connectors for Nessus are available:

  • Nessus Importer retrieves existing scan results from your Nessus server.
  • Nessus Scanner can schedule scans on your Nessus server.
  • Nessus XML imports xml (.Nessus2) files.

First two connectors work with Nessus server directly. And they probably won’t work anymore with Nessus Professional 7, because of API removing (see “New Nessus 7 Professional and the end of cost-effective Vulnerability Management (as we knew it)“). If Nessus server is deployed on-premise you should use special Kenna Virtual Tunnel.

Last “Nessus XML” connector is the most flexible. No matter how you got your scan results, it will be possible to import them to Kenna. See how to get XML reports from from Nessus server in a post “Retrieving scan results through Nessus API“.  You can upload XML scan results using Kenna web GUI (not very efficient way, but for testing – why not?) or REST API.

To use Kenna REST API you will need an Application Token. Go to the the Settings menu -> Applications:

Making simple Nmap SPA web GUI with Apache, AngularJS and Python Twisted

The last time I was developing dynamic web applications years ago. I used CGI and PHP back then. 🙂 Now I am really interested in a modern approach, when you have a Single Page Web Application (SPA) written in HTML and JavaScript, that makes http requests to some external API.

It’s pretty cool, because your application becomes API-centric naturally. You work on human interface and improve integration capabilities at the same time. And the task of securing your web app mostly reduces to securing your formalized API.

nmap SPA GUI

The very best way to learn something new is to write a post about this stuff. 😉 Here I will reproduce my own steps of making a very basic web app:

  1. Launch Apache web-server with http/https.
  2. Make a simple API service: Nmap wrapper.
  3. Make a web-application with “multipage” experience. There should be at least two pages: Scan and About.
  4. On Scan page it will be possible to input a target (hostname or IP), scan arguments and  launch scan by clicking on the button. The same behavior will be if the target will be passed as a parameter in address bar.
  5. On other pages should be some static text.

As you can see, it is a very limited task, but it should clear up the most confusing parts of the process.

Confluence REST API for reading and updating wiki pages

In previous posts I wrote how to automate the work with Atlassian Jira, including automated ticket labeling. Now let’s try to use REST API of another popular Atlassian product – Confluence wiki engine.

Confluence REST API

What you may want to automate in Confluence? Obviously, it may be useful to read the pages that your colleagues regularly update and then use this data in some scripts as an input. You may also want to update your own Confluence pages, for example to post Vulnerability Scanning results. 😉

Vulners Nmap plugin

In previous post about Vulners vulnerability detection plugins for Burp and Google Chrome, I mentioned that it would be great to have a plugin for some free publicly available tool, like Nmap. And guys from the Vulners Team have recently released Nmap plugin. Isn’t it awesome? 🙂

Vulners Nmap vulnerability detection plugin

To detect vulnerabilities with Vulners Nmap plugin, you need to download the script and run it like this:

$ wget -O vulners.nse https://raw.githubusercontent.com/vulnersCom/nmap-vulners/master/vulners.nse
$ nmap -sV --script vulners.nse corporation.com

The output you can see on the screenshot above.

First of all, I need to say that it’s not the full analogue of the plugins for Burp and Google Chrome.

In the current version it doesn’t analyse the content and headers of the site. It doesn’t detect vulnerabilities of standard Web applications. From the other hand, this plugin can detect vulnerabilities of network services, that plugins for Burp and Chrome obviously won’t detect.

Processing .docx and .xlsx files with Python

MS Office documents are probably one of the most inconvenient and poorly formalized data sources. It’s much better to keep all the data in specialized databases or at least in wiki. But in real life, MS Office documents are in active use in nearly every organization. Simply because it is a flexible and easy tool that anyone can use. That’s why it’s important to know an automated ways for processing such files.

Processing MS office files with python

You can easily edit .docx files without any libraries. Technically it’s just a zip archive. So, you can unzip it, make a replacement in the document.xml file and make a zip it again. It’s much better than dealing with old binary .doc files. But there are even more elegant ways.

Let’s says, we need to read data from .xlsx document and generate .docx files based on some existing template. To work with .xlsx files I will use openpyxl python library.
