Facebook wants to sell every Ad and you on the Web. The social network will show ads to non-Facebook users on other websites.

Companies like Facebook and Google offer you their services for free, but free always has a cost.

Force HTTPS On Your WordPress Site

2016-05-12 2 min read Security Erwin Bierens

I’m running my wordpress site for quite some time now.. My site is HTTPS enabled and signed with a certificate. HTTP was also possible in the past for reaching my site. In this guide i’m going to point all of the pages (including the administrative) to force HTTPS.

To simplify this, the guide will build into the following 3 parts:

  1. Force SSL for administrator pages (including the login page)
  2. Secure all normal pages with HTTPS
  3. Change .htaccess to redirect all HTTP to HTTPS

When all of this is completed you should have a WordPress site completely running secure with HTTPS.

This how to describes how to configure Kali to use a openVPN for securing your traffic.

Why should u use VPN?

Here’s my top 5 why you want to use a VPN service.

  1. VPN provides Privacy and hides your own External IP address.
  2. Use any network (public or private or free (hotspot WiFi) with encryption.
  3. Login to your home or Work network from anywhere with confidence of encrypted traffic.
  4. Bypass censorship and content monitoring  by goverments.
  5. Browse and bypass Firewall and censorship policy from Anywhere!

As you can see from the list above, VPN not necessarily hides everything. Search engines  like google, bing and yahoo can still recognizes you based on your cookies or account sign-in. So make sure you use tools like Bleachbit (clear browsing data etc) and enable plugins in your browser for tracking and ads (privacy badger, uBlock Origin or Privacy.net analyzer).
