Using the client as a pivot point

by Kevin Cardwell | June 2014 | Networking & Telephony Open Source

This article is written by Kevin Cardwell, the author of the Building Virtual Pentesting Labs for Advanced Penetration Testing book. This article is about using the client as a pivot point.

When we compromise a machine, the next thing we want to do is use the client source to our advantage. This is because we know most networks are configured with the locations that are inside the network architecture being considered at a higher level of trust and not with a location that is outside the network. We refer to this as pivoting.

(For more resources related to this topic, see here.)

Writing Tag Content

by Vitor Subtil | June 2014 | Cookbooks Open Source

The article by Vitor Subtil, the author of Near Field Communication with Android Cookbook, explains that the NFC Forum is responsible for developing standards-based NFC specifications to allow interoperability between different devices and tags. One of the specifications created by the NFC Forum is NFC Data Exchange Format (NDEF). The NDEF specification defines the message encapsulation format to exchange information between two NFC-enabled devices or devices with the NFC tag. NDEF is a lightweight, binary message format that can be used to encapsulate several custom payloads. Using this abstraction layer allows us to create the standard tag content compatible with all the NFC Forum tag types, ignoring the fact that each tag type has different hardware setups and memory layouts.

In this article, we will cover the following topics:

  • Working with the NDEF record
  • Writing a URI-formatted record
  • Writing a text-formatted record
  • Using Android Application Record
  • Working with external types

Signal Processing Techniques

by Ivan Idris | June 2014 | Open Source

In this article by Ivan Idris, author of Learning NumPy Array, we will learn about some signal-processing techniques, and we will analyze time-series data with these. As example data, we will use the sunspot data provided by a Belgian scientific institute. We can download this data from several places on the Internet, and it is also provided as sample data by the statsmodels library. There are a number of things we can do with the data, such as:

  • Trying to determine periodic cycles within the data. This can be done, but this is a bit advanced, so we will just get you started.

  • Smoothing the data to filter out noise.

  • Forecasting.

Building a Web Application with PHP and MariaDB – Introduction to caching

by Sai Srinivas Sriparasa | June 2014 | Open Source Web Development

In this article by Sai Srinivas Sriparasa, author of the book Building a Web Application with PHP and MariaDB: A Reference Guide, we'll learn how caching can be defined as the process of making popular data highly available by temporarily storing the data in memory that allows responding to a request faster by retrieving data from the memory rather than going onto the disk. There are three types of caching, as follows:

  • Caching in the database
  • Caching in the application
  • Content caching

Selecting and initializing the database

by Krasimir Tsonev | June 2014 | Open Source Web Development

To build a blog application, we need a database that will store the published articles. In most cases, the choice of the database depends on the current project. There are factors such as performance and scalability and we should keep them in mind. In order to have a better look at the possible solutions, we will have a look at the two of the most popular databases, MongoDB and MySQL, in this article by Krasimir Tsonev, the author of Node.js Blueprints. The first one is a NoSQL type of database. According to the Wikipedia entry (http://en.wikipedia.org/wiki/NoSQL) on NoSQL databases:

"A NoSQL or Not Only SQL database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases."
