Understanding VPN

What is Virtual Private Network (VPN)?

A virtual private network (VPN) is a technology for using the Internet or another intermediate network to connect computers to isolated remote computer networks that would otherwise be inaccessible. A VPN provides varying levels of security so that traffic sent through the VPN connection stays isolated from other computers on the intermediate network, either through the use of a dedicated connection from one “end” of the VPN to the other, or through encryption. VPNs can connect individual users to a remote network or connect multiple networks together.

For example, users may use a VPN to connect to their work computer terminal from home and access their email, files, images, etc.

Through VPNs, users are able to access resources on remote networks, such as files, printers, databases, or internal websites. VPN remote users get the impression of being directly connected to the central network via a point-to-point link.

VPN systems can be classified by:

  • The protocols used to tunnel the traffic
  • The tunnel’s termination point, i.e., customer edge or network-provider edge
  • Whether they offer site-to-site or remote-access connectivity
  • The levels of security provided
  • The OSI layer they present to the connecting network, such as Layer 2 circuits or Layer 3 network connectivity

Security mechanisms

VPNs typically require remote access to be authenticated and make use of encryption techniques to prevent disclosure of private information.

VPNs provide security through tunneling protocols and security procedures such as encryption. Their security model provides:

  • Confidentiality such that even if traffic is sniffed, an attacker would only see encrypted data which he/she cannot understand
  • Allowing sender authentication to prevent unauthorized users from accessing the VPN
  • Message integrity to detect any instances of transmitted messages having been tampered with

Secure VPN protocols include the following:

  • IPSec (Internet Protocol Security) was developed by the Internet Engineering Task Force (IETF), and was initially developed for IPv6, which requires it. This standards-based security protocol is also widely used with IPv4. Layer 2 Tunneling Protocol frequently runs over IPSec. Its design meets most security goals: authentication, integrity, and confidentiality. IPSec functions through encrypting and encapsulating an IP packet inside an IPSec packet. De-encapsulation happens at the end of the tunnel, where the original IP packet is decrypted and forwarded to its intended destination.
  • Transport Layer Security (SSL/TLS) can tunnel an entire network’s traffic, as it does in the OpenVPN project, or secure an individual connection. A number of vendors provide remote access VPN capabilities through SSL. An SSL VPN can connect from locations where IPsec runs into trouble with Network Address Translation and firewall rules.
  • Datagram Transport Layer Security (DTLS), is used in Cisco AnyConnect VPN, to solve the issues SSL/TLS has with tunneling over UDP.
  • Microsoft Point-to-Point Encryption (MPPE) works with the Point-to-Point Tunneling Protocol and in several compatible implementations on other platforms.
  • Microsoft’s Secure Socket Tunneling Protocol (SSTP), introduced in Windows Server 2008 and in Windows Vista Service Pack 1. SSTP tunnels Point-to-Point Protocol (PPP) or Layer 2 Tunneling Protocol traffic through an SSL 3.0 channel.
  • MPVPN (Multi Path Virtual Private Network). Ragula Systems Development Company owns the registered trademark “MPVPN”.
  • Secure Shell (SSH) VPN – OpenSSH offers VPN tunneling (distinct from port forwarding) to secure remote connections to a network or inter-network links. OpenSSH server provides a limited number of concurrent tunnels and the VPN feature itself does not support personal authentication.

Authentication

  • Tunnel endpoints must authenticate before secure VPN tunnels can be established.
  • User-created remote access VPNs may use passwords, biometrics, two-factor authentication or other cryptographic methods.
  • Network-to-network tunnels often use passwords or digital certificates, as they permanently store the key to allow the tunnel to establish automatically and without intervention from the user.


Popular Content Management Systems Online

Content Management System is like backbone of the majority of the sites on the web today. If we see many Personal or Business websites or blogs, many of them are created using CMS. CMS is an user friendly software to build sites, even if you don’t have a knowledge of coding or designing skills.

What is CMS?

Content Management Systems (CMS) are designed to simplify the process of publishing content to the web, by allowing people to add content to the web without requiring technical knowledge of HTML to do so.

As per my research, here are popular CMS softwares being used by most of the people.


WORDPRESS

WordPress is the leader in Content Management System for its excellent functionalities. It’s key features and impressive Customer Service Support made it to stand on the top.

WordPress began as a simple blogging software, but has developed in to fully functional CMS by using thousands of themes, widgets, and plugins. Many big brands using WordPress for their web presence.

WordPress allows you to build any kind of site you want: business site, blog, portfolio, and so many. Your site looks good on any device because they provide responsive and mobile themes. WordPress statics gives you the detailed report of your visitors with colorful graphical representation.


DRUPAL

Drupal is a community publishing system, though it is well known as a CMS. Drupal has best features like menu management and user management. You can use these tools to create Social networking pages, blogs, forums, websites and more.

Main advantage is you can use this software to create a range of content types like blog stats, texts, polls, videos, etc. In fact, Drupal is as good as any enterprise-grade CMS when it comes to availability, security, manageability, reliability, and security of online resources.


JOOMLA

Joomla is a free and open-source content management system (CMS) for publishing web content. It is built on a model–view–controller web application framework that can be used independently of the CMS that allows you to build powerful online applications.

The platform is user friendly, extendable, multilingual, accessible, responsive, search engine optimized and so much more.

Joomla provides also another way to get started without having to install it. This is the easiest way to start your first Joomla website immediately. You can launch a totally free and fully functional website in seconds and start publishing your content online immediately.


MAGENTO

Magento is the leading platform for open commerce innovation. Whether you’re looking for a small business solution in an environment where nobody really understands technology, or you’re working from a corporation that needs a professional enterprise eCommerce solution — Magento is likely to be a choice that won’t disappoint you in either way.

Magento is extremely easy to use and will facilitate the work with servicing of clients, which is a very important criteria for today’s eCommerce websites. In case you were wondering whether to use Magento for your website development project, keep in mind that it is vital your site be mobile-optimised.


BLOGGER

Blogger has evolved drastically over the years. But, it keeps its legacy towards being a blogging platform. Developers utilize it as a content management system in more ways than one.

In recent years, a lot more flexibility was introduced in the way Blogger sites can be styled. This means that photographers, foodies and creatives have more room for building a content platform that suits their needs. Blogger is part of Google, and offers a range of features like custom domains, custom styles, and customization options.


TYPO3

TYPO3 is popular among corporate websites, thanks to its integration of features that would otherwise require extensions or plugins. We all know that these slow down the site and overall site performance nut TYPO3 integrated them for you. The developers made TYPO3 highly flexible. You can also extend it using new functions without writing any program code.

The biggest argument about TYPO3 versus other content management systems is that TYPO3 has been built exclusively to serve sites of a much larger magnitude, as well as to be a native content management platform, whereas platforms such as WordPress are traditionally considered to be native blogging platforms.


SHOPIFY

Shopify is another eCommerce platform that is more focused on helping freelancers, small businesses. It also helps corporation size businesses that need reliable and secure eCommerce platform services. It has been around for long enough to be respected as one of the leading eCommerce content management platforms.

It’s also home to some several million community members who actively use Shopify to sell, buy and trade products. Shopify works beautifully with any type of device. This makes it very appealing to those who don’t have a huge budget to shell out on custom designs. Besides that, Shopify offers a range of designs which you can fully optimize yourself.

Web Hosting Guide [2019]

If you are new to website development or blogging, then you will have a question – What is Hosting?

Web Hosting


Web Hosting means storing websites on a server.

The companies offering servers to store web pages are called as Web Hosts. The stored web pages available online via WWW (World Wide Web).

The servers are made available 24×7 to make websites run online anytime. It is not possible to make our computer available 24 hours to run a website. Hence, hosting companies run servers all time. Every server has an unique IP address. Remembering IP addresses is very difficult, hence domain names were given to every website by webmasters to host on servers.

Types of Hosting


There are different types of hosting services available to make it easy for every kind of customer. They can choose hosting service based on their need.

  • Shared Hosting
  • Virtual Private Hosting (VPS)
  • Dedicated Server
  • Reseller Hosting
  • Grid Hosting

Shared Hosting


The name itself describes that sharing space with others. When you are hosting your website on a server, there are many other websites also will be stored in the same server along with you. You need not to worry about privacy. Every website will be given an unique domain name to avoid complexions.

Each website has web space and a set of bandwidth limit. Shared solutions often offer multiple software solutions like email, database, and many different editing options. Technical support tends to be good.


Pros


  • Low Cost.
  • Good for small business and average traffic.
  • Multiple Software Options.
  • Own Domain Name.
  • Good Customer Support.

Cons


  • Reduced security due to multiple sites on same server.
  • Restrictions on traffic volume.
  • Less database support.
  • Restricted Software Support

Virtual Private Hosting [VPS]


VPS also known as Virtual Dedicated Server. A server has been divided into several virtual servers ( a virtual server is a software implementation of a machine (i.e. a computer) that executes programs like a physical machine. Each virtual machine can run its own full-fledged operating system and can be independently rebooted.).

A single computer can run many virtual machines side by side. Multiple operating systems can co-exist on the same computer, in strong isolation from each other. Each VPS operates almost entirely independently of the other accounts that share the server space. This is particularly beneficial to hosting providers, who can offer customers their own virtual machine – or in other words, VPS hosting.


Pros


  • Less expensive than a full dedicated hosting plan.
  • Many VPS plans can be customized to meet your needs.
  • Many VPS hosting plans are easily scalable.
  • You have a lot more control over your virtual server than you do with shared hosting.
  • You can choose from semi managed hosting where the web host handles some maintenance and fully managed services.

Cons


  • It is more expensive than shared hosting.
  • Limited ability to handle high traffic levels or spikes.
  • There are a few issues you may encounter if the host does not handle VPS correctly.
  • Some web hosts offer VPS hosting but do not allocate the resources appropriately.
  • This option requires regular maintenance including security patches and system updates.

Dedicated Hosting


The name itself reveals that you have a server all for yourself in dedicated hosting. You can have full control over it, which means control over everything from security to operating system. With a dedicated server, you don’t have to worry about other websites on a shared server taking up your resources and slowing your website down.

There’s an unparalleled level of freedom that comes with a dedicated server. You aren’t sharing the server in any capacity, so you can, essentially, do what you will with it. If you need a very specific set up to run your site correctly, it’s well within your reach with a dedicated host.


Pros


  • Good for Large Business Companies.
  • If you have high traffic, it’s the best one.
  • Multiple Domain names you can get.
  • Powerful email solutions.
  • Strong Database Support.
  • Unlimited Software Support.

Cons


  • Very Expensive.
  • Requires High Skills.
  • You could get a completely unmanaged service where you would need to install the OS yourself, let alone all the tools needed to run a web server, provide security scanning, malware removal and so on.

Reseller Hosting


Reseller hosting packages are basically a shared hosting account with extra tools to help you resell hosting space. Reseller packages come with greater technical control (often via the Web Host Manager (WHM) control panel), billing software to help you invoice clients and other extra perks.

Resellers can easily add, modify or delete client accounts at any point of time. It allows resellers to allocate more resources or degrade the resources allocated to a hosting account. With the advanced and appealing features reseller’s can achieve the greater level in the reseller hosting industry.

Pros and Cons

Price is definitely the biggest advantage of reseller hosting. A lot of the reseller hosting plans are relatively cheap, perhaps a few dollars a month. However, as mentioned before, unlike established web hosting firms, the resellers might not be able to provide reliable technical support.

Grid Hosting


Grid hosting is a service that provides grid computing capabilities to its clients. Grid computing is the application of multiple computers (or servers) to a problem that requires access to a large number of computing cycles. Much like clustered hosting, grid hosting makes it less likely that a spike in resource needs will take your site offline.

Resources that a single machine can offer are likely to get exhausted eventually particularly if these resources must be shared among many users. So, grid hosting is far more flexible because your virtual site can use resources from more than a single machine within the cluster. This helps to increase site reliability and even if a single node in the grid fails to perform, the overall performance is not affected. This is because another node will take over unlike shared or dedicated hosting where the site must go offline in such a situation.
