Free and Open-Source Tool for
Social Network Analysis

Social Network Visualizer (SocNetV) is a cross-platform, user-friendly free software application for social network analysis and visualization. With SocNetV you can:

  • Draw social networks with a few clicks on a virtual canvas, load field data from a file in a supported format (GraphML . GraphViz . Adjacency. EdgeList, GML, Pajek. UCINET. etc) or crawl the internet to create a social network of connected webpages.
  • Edit actors and ties through point-and-click, analyse graph and social network properties, produce beautiful HTML reports and embed visualization layouts to the network.
  • Standard graph and network cohesion metrics, such as density . diameter . geodesics and distances . connectedness . eccentricity . clustering coefficient . reciprocity, etc.
  • Matrix routines: Adjacency plot, Laplacian matrix, Degree matrix, Cocitation, etc
  • Advanced measures for social network analysis such as centrality and prestige indices (i.e. eigenvector and closeness centrality. betweenness centrality. information centrality. power centrality. proximity and pagerank prestige).
  • Fast algorithms for community detection. such as triad census . clique census ,etc.
  • Structural equivalence analysis, using hierarchical clustering. actor similarities and tie profile dissimilarities, Pearson coefficients.
  • Layout models based either on prominence indices (i.e. circular, level and nodal sizes by centrality score) or on force-directed placement (i.e. Eades Spring Embedder. Fruchterman-Reingold. etc) for meaningful visualizations of the social networks.
  • Multirelational network loading and editing. Load a social network consisting of multiple relations or create a social network on your own and add multiple relations to it.
  • Random network creation using various random network generation models (Barabási–Albert Scale-Free. Erdős–Rényi. Watts-Strogatz Small-World. d-regular, ring lattice, etc)
  • Famous social network analysis datasets. i.e. Padgett’s Florentine families.
  • Built-in web crawler to automatically create “social networks” from links found in a given initial URL.
  • Comprehensive documentation. both online and inside the application, which explains each feature and algorithm of SocNetV in detail.

Source code, packages and executables for Windows, Linux and Mac OS X are available in the “Downloads ” page.

The program is Free Software, licensed under the GNU General Public License 3 (GPL3) .
You can copy it as many times as you wish, or modify it, provided you keep the same license. The documentation is also Free, licensed under the Free Documentation License (FDL).

Types of Wireless Network Security keys and how to secure them in Windows

Security of your Wi-Fi network is as much important as of your computer. All your personal information and files on your wireless network can be seen by people who are connected to your Wi-Fi network signal. This can lead to identity theft and other malicious acts.

Wireless Network Security keys

A network security key or passphrase can help protect your wireless network from this type of unauthorized access. It s easy to set up a secured Wi-Fi connection in Windows 7, the Set Up a Network wizard will guide you through setting up a security key.

If you already have a configured device, then go to Network and sharing center. in the left pane, click on Manage Wireless networks and then select the network for which you want to configure the security key. Click on properties and then click on Security tab and change the security key.

I don t recommend using Wired Equivalent Privacy (WEP) as your wireless security method. Wi Fi Protected Access (WPA or WPA2) is more secure.

Difference between WEP and WPA/WPA2 encryption methods for wireless networks

Wi Fi Protected Access (WPA and WPA2)

WPA and WPA2 require users to provide a security key to connect. Once the key has been validated, all data sent between the computer or device and the access point is encrypted.

There are two types of WPA authentication: WPA and WPA2. WPA2 is the most secure. In WPA-Personal and WPA2-Personal, each user is given the same passphrase. This is the recommended mode for home networks. WPA-Enterprise and WPA2-Enterprise are designed to be used with an 802.1x authentication server that distributes different keys to each user. This mode is primarily used in work networks.

Wired Equivalent Privacy (WEP)

WEP is an older network security method that s still available to support older devices, but it s no longer recommended. When you enable WEP, you set up a network security key. This key encrypts the information that one computer sends to another computer across your network. However, WEP security is relatively easy to crack.

There are two kinds of WEP: open system authentication and shared key authentication.

Neither is very secure, but shared key authentication is the least secure of the two. But a hacker can easily hacks it using some Wireless network analysis tool.

For this reason, Windows 7 / 8 doesn’t support automatically setting up a network using WEP shared key authentication.

If, despite these warnings, you still want to use WEP shared key authentication, you can do so by following these steps:

To manually create a network profile using WEP shared key authentication

Windows 10 how to: Managing wireless network connections

Windows 10 means new settings and options to learn and get used to. One of those is managing wireless network connections. In Windows 10 you can easily manage your network connections and can share those connections with your contacts using Wi-Fi Sense.

To manage wireless settings, go into the Windows 10 settings menu and select Network and Internet. You can also right click the wireless icon in the action center or type Wi-Fi into Cortana. Once there you can turn Wi-Fi on or off and connect to local networks by clicking them and selecting Connect.

In Advanced Options you can set your device to be discoverable or hidden from other PCs on the same network. You can also turn on and off a metered connection, this is important if you have limited data, for example if you re using the new Surface 3 with LTE .

There’s also a feature in Windows 10 called Wi-Fi Sense. This allows you to store your passwords on various networks across your devices. It also lets you share your Wi-Fi connection with your Outlook, Skype, and Facebook connections without giving them your network password. If you prefer to not share your connection with your contacts you can easily uncheck the boxes in the Wi-Fi Sense menu. At the moment you cannot select specific individuals to share your network connections with over Wi-Fi Sense. Hopefully that feature is available in the future.

Managing wireless networks is pretty easy in Windows 10 and all of the settings are easy to find and are clearly labeled. Jumping between networks with Wi-Fi Sense is easy and most of the settings are easy to personalize, though there are a few customizations not yet available.
