  1. Creating HSTS and Pre-load with Cloudflare

    Most people are familiar with HTTPS and the concept of secure websites. Securing websites become more and more common, which is a really good thing. Not only do we know that the data sent and received from the website is secure, but we also get a sense of knowing we will be alright. We expect that we get confidentiality, authenticity and integrity from modern websites. After all, we see sites every day with this:This is becoming more and more common, and according to Scott Helme almost 31% of the...

Its so recommended that you review all of this policies.As administrator, you can create additional malware or spam policies and applies it to specific users or groups.The malware filter...
  3. Custom user roles and role-based authorization in ASP.NET core

    I've recently been trying to contribute to the developer community, in more ways than I previously have. One of the areas I decided to delve into, is spending more time on tech forums and resources like StackOverflow.  Well not for asking questions or checking for answers, but more for answering as many questions as I possibly can. The aim is to provide answers primarily to questions budding developers are asking. so Let's hope I do a lot of that as time goes on. Hey, I might...
  4. Visual Studio: Creating and managing digital certificates in C#

    Digital Certificates are used for secure communication between two parties. In digital certification we ensure that the peoples who are using our apps or services are securely communicating with each other and those peoples can be individual consumers or businesses.In Digital Certification we use both Hashing and Asymmetric encryption for creating digital signatures.After encrypting the hash of data we obtain a digital signature later which is used for verification of data.As there are a lot more...
  5. How to install pfSense onto a CheckPoint Firewall Appliance

    pfSense is an Open Source firewall platform that can also be used for site to site connectivity as well as mobile client connectivity.Having used pfSense in the past and knowing how robust and secure the platform is, I wanted to see if I could port or install pfSense onto a CheckPoint firewall appliance. I figured that the CheckPoint appliances should have more than enough power to run pfSense.I was able to test the installation of pfSense using a few older CheckPoint appliances that were decommissioned...
  6. Configure RoundCube on Debian 8 (Jessie) - Perfect Server Debian 8 (Apache, BIND, Dovecot, ISPConfig 3)

    Debian 8 (Jessie) doesn't contain RoundCube in it's repositories. Why, I don't know :) . In ISPConfig3, Perfect Server, Debian 8, you get SquirrelMail, but I don't like how it looks. With some trouble setting it up, I managed to configure RoundCube on Debian 8 and make it wokring with ISPConfig3. Used many sources to make it work and decided to create this manual that you’re reading.I presume that you have configured your server with Perfect Server Debian 8 (Apache, BIND, Dovecot, ISPConfig 3) configuraton...
  7. Https Redirect with Asp.Net Core RC2 And Kestrel on Windows

    June 1, 2016I've learned a lot about Asp.Net Core RC2, Kestrel and ports as I failed in various attempts to get a http to https redirect. I share this as a retrospective for myself and in hopes of helping you avoid the swamp and to stay on the narrow road.Update: This approach works with the 1.0 release of Asp.Net Core as well as RC2.Host Asp.Net with Kestrel without IIS for an internal app. I'd like to hit the machine at http://machine-name/ and get redirected to a login at https://machine-name...
  8. One Weird Trick To Improve Web Performance

    The web is chock full of web performance advice. There are books on the subject, I've written articles about them, and there are countless case studies proving just how critical web performance is. All of these tips, patterns and "best practices" are important to understand and apply when appropriate, but the current state of the art, science and technology that drives the web (not to mention the politics!) has created a climate in which one simple web performance trick will likely provide...
  9. Migrating Physical to Virtual...

    Disk2vhd is a utility that creates .VHD (Virtual Hard Disk) a virtual disk version of physical “bare-metal” disk or disks for use in Microsoft Hyper-V, System Center Virtual machine Manager, AppController and Microsoft Azure. The difference between Disk2vhd and other physical-to-virtual tools is that you can run Disk2vhd on a system that’s online. Disk2vhd uses Windows' Volume Snapshot capabilities to create consistent “point-in-time” snapshots of the volumes you want to include in your conversion....
  10. "Let's Encrypt" Azure Web Apps the Free and Easy Way

    The process of acquiring TLS/SSL certificates has never been one that I'd call smooth. Its certainly gotten easier and cheaper over the years - I remember once having to prove I received a piece of physical snail mail to satisfy a certificate authority - but there's still plenty of room for improvement.> Aside: SSL (Secure Sockets Layer) is the name of the proprietary protocol originally developed by Netscape. When the IETF improved and standardized the protocol in 1999 with RFC 2246, they renamed...
