What is Healthcare Industry ?

    The healthcare industry (or the medical industry ) is the category of stocks relating to medical and healthcare goods or services. The healthcare sector includes hospital management firms, health maintenance organizations (HMOs), biotechnology and a variety of medical products. It’s an aggregation and integration of sectors within the economic system. They also aim to provide goods and services to treat patients with curative, preventive, rehabilitative, and palliative care. It includes the generation and commercialization of goods and services lending themselves to maintaining and re-establishing health. The modern healthcare industry is divided into many sectors. They all depend on interdisciplinary teams of trained professionals and paraprofessionals to meet health needs of people.

     

     

    Why does Health Care need IT alongside ?

    IT sector aims to minimize human efforts and increase the overall throughput. As time went by it found its use in different traits allover the market. Some of them include automation, reduced human intervention so that a machine can work independently, where it is supplied with the necessary details. Machines have a very precise and fixed way of doing work so that it can gain efficiency at the end of the day.

    We know that healthcare in the past, operated on manual tools and machines which took a lot of time to give the user a proper result. It not only made the whole process easy but gave a great advantage to the user in terms of flexibility. Now there is no need for a Doctor to wait for a report as it is available  within minutes.

     

    Health Care uses something called as the PACS. A picture archiving and communication system (PACS) is a computerized means of replacing conventional radio-logical film with Computer Images.

    This reduces a lot of paper work and the clutter that comes along with it. Now patients can carry their entire case history in a small object like a CD or a DVD. This is not only cost effective but very clean and efficient.

    A Short Review on Spam Experts

    Spam Experts is a spam filtering service. It provides both inbound and outbound filtering, along with mail archiving.

     

    Filtering both Inbound and Outbound

    Inbound filtering is what we would expect from a spam blocking appliance. It will block incoming spam. First, a domain is added to SpamExperts, the MX records for that domain needs to be changed to SpamExperts MX records. Once an email comes in it is checked via the Spam Experts servers and tested to see if it’s spam. If it is not spam, the mail will directly go to the client’s Inbox. If it is spam, it will be placed into quarantine.

    Outbound filtering allows you to use the SpamExperts servers as a smart host. Your mail will be sent through the cluster where it is scanned for spam. If too much spam is identified then the account will be locked. This is useful at preventing a poor mailing reputation in the case of an account compromise or similar. This requires Mail server configuration changes to configure the SpamExperts servers as a smart host. An outbound account must also exist within SpamExperts for authentication purposes.

     

    Levels of Access

    There are 3 different types of accounts which are used with Spam Experts:

    1. Super-admin: This account can do anything, create new admins, access all admins and their domains, etc.
    2. Admin: This account can create new domains and make some API calls. Each client will have a single admin account. This account can be used to access all domain users created under that account.
    3. Domain user: Each domain created under a clients admin account will have a domain user associated with it. This account is used to inspect the logs for a domain, manage the quarantine, and whitelist/blacklist senders/recipients.

    Each level of access has full control over the level of access below it. For example, a super-admin can use the SpamPanel GUI to log in as any admin user. An admin user can use the GUI to access any domain user for domains associated with that admin. Domain users can access the email users of any users created under that domain.

     

    What people say and what I think of the service.

    I am using Spam Experts for some time now and seems like it performs exactly as it promises. Truly the guys at Spam Experts have done a great job.

    I have been reading post everywhere people saying that it doesn’t work, first of all, guys you should go through the documentation especially relevant details like filters and checkups that are done and in addition to that ask your host the provider about it. There are a handful of settings that needs to be adjusted just to get started. Finally, I must say that it indeed is a beautiful tool.

    Seriously, guys there I nothing so called 100% spam proof as hackers/spammers find a way to get in eventually, but SpamExperts is actually worth it.

    New to Web Hosting, What Control Panel do I use ???

    In the last few years serving the Web Hosting Industry I have run into numerous times when the above is asked and people get confused.

     

    This may looks stupid in the first but actually matters a million. Control Panel is something that automates/Simplifies our day to day job. Not all of us are experts in the command line and neither like spending hours figuring out what went wrong in the first place.

     

    There are numerous control panels both free and paid that does exactly this for you.

    Paid : cPanel, Plesk (They are the best ones)

    Free : VestaCP, Kolaxo, CentOS Web Panel, ISPconfig should be the ones called popular.

     

    The above also depends on what type of hosting your love or prefer, windows hosting mainly comes with Plesk alone, whereas Linux hosting comes with varieties. Shared hosts with Windows environment give away Plesk and Linux cPanel similarly. 🙂

     

    There is a big confusion among fans as to which control panel to use but clearly, it is up to you as to which one to use, Plesk seems great but has many limitations and is also cost confusing if you do not know what are your needs. cPanel, on the other hand, is clear about this, it has basically 2 types of licences, VPS and Dedicated server licence.

     

    Now if you are an advanced user and have your own server and do not want a paid control panel and want to save some bucks go for the free control panel as you already love command line so just a little Google Search before hand will save a tonne of money.

     

    The Basic requirement is that the server should be online and get as much resource as possible to the hosted site and not take up and just run the panel services. More resource available the better your server performance and that in turns run your site lighting fast. 🙂

     

     

    Hope this helps and the next time you are confused you find a light in the dark.

    Stands for “Secure Sockets Layer.” SSL is a secure protocol developed for sending information securely over the Internet. Many websites use SSL for secure areas of their sites, such as user account pages and online checkout. Usually, when you are asked to “log in” on a website, the resulting page is secured by SSL.

    SSL encrypts the data being transmitted so that a third party cannot “eavesdrop” on the transmission and view the data being transmitted. Only the user’s computer and the secure server are able to recognize the data. SSL keeps your name, address, and credit card information between you and merchant to which you are providing it. Without this kind of encryption, online shopping would be far too insecure to be practical. When you visit a Web address starting with “https,” the “s” after the “http” indicates the website is secure. These websites often use SSL certificates to verify their authenticity.

    While SSL is most commonly seen on the Web (HTTP), it is also used to secure other Internet protocols, such as SMTP for sending e-mail and NNTP for newsgroups. Early implementations of SSL were limited to 40-bit encryption, but now most SSL secured protocols use 128-bit encryption or higher.

    Providers

    Worldwide, the certificate authority business is fragmented, with national or regional providers dominating their home market. This is because many uses of digital certificates, such as for legally binding digital signatures, are linked to local law, regulations, and accreditation schemes for certificate authorities.

    There is a good news for all guys who are passionate about using SSL but don’t ant to spend money. Let’s give LetsEncrypt a try.

    Each certificate is issued for 90 days and then you will have to reissue them, that too is free. 🙂

     

    Just contact your provider for the same as they may have a cPanel/Plugin setup for you to get it in a click. 🙂

    PCI standard or Payment Card Industry Data Security Standard

    The Payment Card Industry Data Security Standard (PCI DSS) is a proprietary information security standard for organizations that handle branded credit cards from the major card schemes including Visa, MasterCard, American Express, Discover, and JCB.

    The PCI Standard is mandated by the card brands and administered by the Payment Card Industry Security Standards Council. The standard was created to increase controls around cardholder data to reduce credit card fraud. Validation of compliance is performed annually, either by an external Qualified Security Assessor (QSA) that creates a Report on Compliance (ROC) for organizations handling large volumes of transactions or by Self-Assessment Questionnaire (SAQ) for companies handling smaller volumes.

    Basics of getting PCI Compliant.
    –+-
    1) First of all, if is hardly possible of a Shared hosting environments as they will not mitigate certain threats coz others customers will have multiple issues connecting to the services.

    2) If you own a Dedicated server/VPS you are good to go.

    3) There are tonnes of companies who provide PCI scan reports and will finally get you the PCI Compliant seal that you can proudly put on on your site.

    4) There are major three type of ratings that you will see, High >> Red, Normal >> yellow and Pass >> green.

    High are potential threats and needs to be mitigated at the earliest.

    Medium and pass can be ignored, as they don’t really matter.

    5) There is a good point that you wanna keep in mind, if you are running Old CentOs versions or any other flavours like Ubuntu 12.x or below you should seriously upgrade first and then submit for the PCI scan.

    For guys with CentOS servers 6.8 and above you really do not need to do anything special. Redhat and CentOS come in with a feature called backporting, and they down;load the patched on the current builds so no matter what comes out you are alwaye secured. You may want to call in your host and get them to check if all the CVE are backported.

    Get the results that they give you and provide the same to the scanning commany so that they can whitelist the results oin the next scan. This way it may take a couple of scans but you will get the goal at hand. 🙂
    —-

    To whom does the PCI DSS apply?

    The PCI DSS applies to ANY organization, regardless of size or number of transactions, that accepts, transmits or stores any cardholder data

    Am I PCI compliant if I have an SSL certificate?

    No. SSL certificates do not secure a web server from malicious attacks or intrusions. High assurance SSL certificates provide the first tier of customer security and reassurance such as the below, but there are other steps to achieve PCI compliance.

    A secure connection between the customer’s browser and the web server
    Validation that the website operators are a legitimate, legally accountable organization

    What is a vulnerability scan?

    A vulnerability scan involves an automated tool that checks a merchant or service provider’s systems for vulnerabilities. The tool will conduct a non-intrusive scan to remotely review networks and web applications based on the external-facing Internet protocol (IP) addresses provided by the merchant or service provider. The scan identifies vulnerabilities in operating systems, services, and devices that could be used by hackers to target the company’s private network.

    Key Managed and Unmanaged Hosting Differences

    When it comes to hosting, think of management as planned support.

    On a managed hosting package, the host offers support for every problem or task, emergency or routine. There’s a limit, obviously, in that you may not get support for a coding problem on your blog. But the operating system, control panel, server setup and any pre-installed applications are all managed – supported, in other words. Often, managed hosting comes with automated backup and monitoring.
    Unmanaged hosting is cheaper because there’s no management – i.e. no routine support. The host will replace failed components, reboot servers, maintain the network and keep the lights on, but it won’t support any software or install anything for you. It’s effectively your computer to maintain and control. You install security patches, you fix weird error messages and you’re responsible for installing everything but the OS. Many hosts won’t even provide a control panel or web server software: it’s up to you to do that.
    If you get really stuck on unmanaged hosting, your host will charge you an hourly rate for basic help. Be warned: it’ll be very expensive, and it’ll probably wipe out the savings you made on buying a cheaper plan.

    The Pros and Cons of Unmanaged Hosting

    Unmanaged hosting gives you complete control: sole access and total freedom, just as though your server were your own computer. Unmanaged services are significantly cheaper than managed services, so if you’re comfortable with your OS, it’s a no-brainer.

    But if you’ll struggle to install a control panel from scratch, you’ll hit problems from day one. And do you really have the time to manage a server on top of all of your other tasks? Could you cope with every eventuality on your own?

    Managed hosting is far less work and requires little expertise. If something goes wrong and you’re stuck, you can call on your host to give you a hand.

    different typesweb hosting

    Shared, Dedicated, VPS, and Cloud hosting Different types explained

    All sites and blogs on the Internet start with hosting.

    Web Hosting 

    is one of those beasts with so many variables that everyone gets lost, even developers with plenty of prior knowledge. In this article I’ll clear up the differences between the most common hosting types: shared, VPS, dedicated and cloud, let’s get started.

    Shared Hosting – Cheapest, Best for Beginners

    Shared hosting is the budget option. It is extremely cheap, but also not very good.
    Some of the most well-known hosts in this segment are Bluehost, Siteground, and A Small Orange.

    VPS Hosting – More powerful than Shared hosting

    VPS stands for Virtual Private Server and is probably the most popular service to upgrade to and it can be the most well-balanced one as well.

    A VPS server is still a shared environment, but the way it is shared is very different.

    First of all, a VPS server is usually limited to 10-20. This decreases stress in itself, but the real improvement comes in the form of the hypervisor – which is the coolest name for something ever.

    A VPS server is literally split into as many parts as there are users. If there are 10 users, 10GB of RAM and 200GB of hard drive space on the server, each user will be able to expand 1GB of RAM and 20GB of space. Once you hit the RAM limit your site may go down, but the others will remain stable. The hypervisor is the one responsible for managing the virtual machines that create this separation within the server.

    Dedicated Hosting – If Your Site Exceeds 100k Visits/month

    This is the hosting service that negates all bad neighbour issues because you are all alone on a server. This provides a host of benefits, but also comes with quite a few downsides.

    Since you get a computer all on your own, many companies allow you to customise it extensively. You may be able to choose the amount and type of memory, the OS to install, and other hardware elements that make up a computer. This gives you a lot of flexibility which may be needed for some specialised software.

    The downside here is that you actually need to know quite a bit about computers and server technology. While there are managed dedicated hosting solutions you’ll still need to do a lot more on your own.

    Cloud Hosting

    Cloud hosting is essentially the same as VPS hosting. Some companies don’t even call their service VPS anymore, the say Cloud or Cloud VPS. Let’s look at what cloud computing is first, and get back to what this has to do with hosting.

    Until now we’ve been talking about computing that is similar to buying unit based products. If I buy a one-use battery and put it in video camera I can use it for a set amount of time until the battery runs out.

    Cloud-based computing is similar to how utilities work. If I plug my video camera into the mains I can use it as much as I need and it will take as much power as it requires at the moment. If it is on standby it will use very little power when it is recording it will use a lot more but the electric system can handle the changes in power requirements.

     

    Conclusion

    Choosing a hosting package can be pretty difficult. The first step is understanding the type of hosting you need: shared, VPS, dedicated or cloud. Hopefully, this article has given you the background to figure that out.

    If you’re just starting out (building your first blog/site) – go with shared hosting. It’s cheapest and usually more than you need at the beginning.
    As the next step, you should take a look at a bunch of companies, I recommend checking our top rated hosts to find the best ones. Look at what’s on offer and compare the RAM, disc space, CDN usage, bandwidth and other quantifiable resources. Then take a look at any additional features on offer.

    At the end of the process, you should have 2-3 favourites at which point it will boil down to personal preference. Perhaps a short talk with support – to gauge their helpfulness – will go a long way.

    meaning of hostingdefinition of hosting

    A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web. Web hosts are companies that provide space on a server owned or leased for use by clients, as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for other servers located in their data center, called colocation, also known as Housing in Latin America or France.

     

    The scope of web hosting services varies greatly. The most basic are the web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a Web interface. The files are usually delivered to the Web “as is” or with minimal processing. Many Internet service providers (ISPs) offer this service free to subscribers. Individuals and organizations may also obtain Web page hosting from alternative service providers. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting often has a higher expense depending upon the size and type of the site.
    Single page hosting is generally sufficient for personal web pages. A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. ASP.NET, ColdFusion, Java EE, Perl/Plack, PHP or Ruby on Rails). These facilities allow customers to write or install scripts for applications like forums and content management. Also, Secure Sockets Layer (SSL) is typically used for websites that wish to keep the data transmitted more secure.
    The host may also provide an interface or control panel for managing the Web server and installing scripts, as well as other modules and service applications like e-mail. A web server that does not use a control panel for managing the hosting account, is often referred to as a “headless” server. Some hosts specialize in certain software or services (e.g. e-commerce, blogs, etc.).
