IoT security: Challenges and tips for securing IoT

Comments off

Internet of Things continues to increase across enterprises globally to unlock new business values. According to Gartner, around 6.4 billion connected devices will be used this year increasing to 20 billion by the end of 2020. As more and more organizations are availing the benefits of Internet of Things to gain a competitive advantage in the market, Internet of Things will soon reach new heights.

We cannot overlook the security concerns that are rising with the growth of connected devices. If we talk about traditional IT security, securing software is of prime importance. However, in IoT both hardware and software are to be protected commonly known as cyber physical security. To protect IoT solutions, it is necessary to have secure arrangement of devices, safe and protected connectivity between cloud and devices and secure data security solutions while processing and storage.  However, challenges are part of every game; similarly here as well certain challenges are faced.

Devices: The arrangement and maintaining IoT devices is challenging because of its scale and geographic distribution.  Sometimes, devices are not supervised carefully and are deployed in hostile environments where uncertain operations are very common.

Connectivity: Since, a large number of devices are connected over the Internet; it poses threats to integrity and privacy of data.

Ubiquitous Data Collection: With connected devices, companies are able to track hold of our private activities. It is in the near future, a digital trail of our everyday lives can be grabbed.

Unexpected use of consumer data: This persistent collection of data certainly gives rise to worries about how personal information will be used? This is a very important issue and such questions will become the future of IoT. We cannot continue to walk on the path of data collection without thinking about such concerns and questions.

An overall strategy is required to secure an IoT infrastructure. Securely arranging devices, protecting data integrity and securing data in cloud etc. should be considered which ensures security at each layer of the infrastructure. Let’s look at some of the tips which can help us to stay safe.

Different network for different users

Wi-Fi supports many smart devices today. However, don’t plug in it in your devices like phones or computer every time you require. Make a special guest network for users to keep untrusted visitors away from your regular network.

Turn off Universal Plug and Play (UPnP)

Devices such as video cameras communicate with router to expose inbound holes which enable them to accept connections from outside. With this, it can easily access from the internet, on the other hand your devices are exposed to the rest of the world. Make sure to switch off universal plug and play on routers as well as on your IoT devices. Assuming that no one will notice while hooking up your device for the first time can prove dangerous.

Keep your IoT devices firmware updated

Patching IoT devices is also important just like your computer. Make it a habit to keep your devices updated though it can be a time consuming task, however, it will keep you and your devices safer compared to other devices which are not updated.

Strong Passwords

Many IoT devices have bugs that enable attackers to leak security information like your Wi-Fi passwords. Make sure your passwords are complex as well as unique.

Devices that work without cloud

IoT devices that are cloud based are less secure and have the potentials to give away more private information than those devices which are not cloud based and can be easily controlled entirely within your home. Try to use IoT devices which are not cloud based as you can easily control them.

Unnecessary Internet Connections

Keep only those network devices which you need. Don’t keep unnecessary connected devices wasting energy and resources. Make sure to eliminate unwanted connections whenever possible.

Don’t connect IoT devices on employer’s network

If your IoT device is insecure, attackers can easily find a loophole and can easily enter the organization. They can steal all important information. If you want to connect your device on employer’s connection, take permission from the IT department as they are in a better position to tell you about the security of your device.

The above mentioned steps are just a part of the never ending list in terms of security. Many more tasks can be performed to make you IoT devices safe and secure. IoT operators should develop best practices to boost security across the globe.

 

 

 

 

Transformation of Commerce with Internet of Things

Comments off

Even the most inane technology is becoming smart day by day starting from fitness trackers to coffee makers. This is just the beginning. The Internet of Things (IoT) is changing everything, changing the way consumers are ordering coffee filters to manage home security. The very material of commerce is revolutionizing.

As mentioned earlier, it is just the beginning. IoT is still in its egg shell and will take the time to completely come out and enter the evolution. Gartner predicts that till the time we reach 2018, hardly people will be prevailing IoT network. In the coming years down the line, we can expect the multiplying number of different products, different devices, and methods to IoT.  According to Cisco, at the end of 2020, there will be 50 million connected devices.

With all this developing, the whole commerce sector is going to revamp itself with the benefits of IoT along with the increased adoption of cloud server hosting. But, merchants and vendors need to consider certain things. Let’s review them one by one

Supply replacement

Supply replacement is the only natural extension of IoT.  For example, the connected devices are programmed in such a way to store at least half-gallon of milk at the starting of the week, the measurement of the milk consumption will be measured by the refrigerator. If the milk dips below a half gallon, a gallon of milk will be added by the refrigerator to the normal grocery store order for Sunday deliveries. But talking about supply replenishment with IoT, something similar is just the beginning and more is yet to come.  In the coming years down the line, you will not have to go at the grocery store to pick up more toothpaste if they are out of stock.

Purchasing Development

Purchasing development is one step beyond supply replenishment. With this consideration, an entire host of choices in consumables can be altered starting from the size of the items to quantities which are purchased from consumer’s point of view.  For example, kitchen devices which are internet connected should inform consumers that instead of going with a 16-oz bottle they should go for 32-oz of olive oil bottle without it going bad and save money.

Purchase development will be performed by IoT which most of us are aware of but never could spare time to give concentrated focus on it. Smart products will have the ability of optimizing sizing, price and also ascertain the best places to buy products. Moreover, with time IoT evolution is much required to cope with the changing technology and make smart decisions.

Product Procurement

Product procurement will enable the products to make the shopping decisions, deciding with an insignificant human intervention which other products to buy. Every individual is not capable of having the tolerance to handle products deciding the purchase and service decision for people, but with IoT, everything can be possible.

IoT can be nascent as of now, but within some years connected and smart products will become more sophisticated, more and more investment will be made in connected products in professional as well as personal life. To cope up with the rapid change, product information should take steps to meet the consumer’s expectations and demands who wish to have best products and services for their requirements. Otherwise, consumers will be left behind with an impaired system leaving them lagging behind.

IoT is completely going to become a revolution and change the purchasing pattern of consumers where just one reminder will be enough to optimize the energy consumption at home.

Witness the Revolution of Cloud Architecture

Comments off

Cloud is no more the cherry on the cake. It is the whole cake that more and more organizations are interested in. Cloud is not an evolution of existing technology, but an actual revolution that has taken place in the world of technology.  Revolutions change the perception and redefine the meanings. Though cloud has evolved since years but it is today that organizations understand the real value of deploying cloud. However, with many advancements made in the cloud technologies, cloud architecture itself has evolved.

With cloud computing, everyone can manage to develop a service with just a penny of investment. Though, the cloud architecture should also scale accordingly. With the changes in the technology and cloud server hosting, it is necessary to keep a pace with the technological changes and adopt new technology to survive in the rat race. Let’s see how the architecture of cloud has revolved with time

Commodity Hardware instead of high-end Hardware

With time this has changed a lot. Some largest cloud service providers use commodity hardware. This commodity hardware is very much prone to breakdowns compared to traditional environments. However, this will not prevent you from using cloud for company applications with high accessibility and high performance needs. As per different resiliency criteria and distribution, it is essential to restructure the cloud architecture.

Dynamic Scaling

One of the essential characteristics of an excellent architecture is scalability. Scaling of architecture is altogether completely different as you need to take into consideration budget allocation, planning, systems reconfigurations, hardware purchase etc. Very steady architectures can be implemented after a period of time and maximum load can be sized which is able to support the service or application.

When we are talking about cloud, resources utilized in cloud are dematerialized and on demand requests are initiated. A high level of abstraction of hardware resources can be managed by Application Program Interface (API) so that provisioning and de-provisioning of resources can be automated. Architecture so deployed should be flexible and adaptable as per the demands and should possess the ability to expand as and when required.

Resiliency in terms of Availability

“Resources are anytime available” is an assumption which is believed in traditional architecture. On the other hand, inaccessibility of resources is an anomaly. It is neither planned nor is it a desirable event. However, in cloud the question of unavailability of resources does not arise as commodity hardware is used. Transient failures come now and then and the architecture so deployed should have the ability to handle such failures. In case of uncertainties, it should be programmed to respond properly and the transaction should be completed. In short, it should be resilient enough. In progressive cloud computing architectures, to create deliberate failures, some agents have been deployed to carry out this activity in production environments to make sure applications respond properly. To gain resilience, a system of queues should be implemented so that the components of the application is coupled loosely and is autonomous.

Distribution and Decomposition of Performance

Technology has some inherent performance constraints like commodity hardware, resource sharing or non-proximity of resources, cloud architectures being sensitive to it. Methods which were earlier deployed to release the stress of the resources such as increasing the bandwidth, number if IOPS, size of the RAM or the processor speed are no longer effective. Scaling up in cloud is very limited and sometimes unmanageable. Instead of focusing on strengthening a single unit of architecture, decomposing the architecture in multiple modules established across various nodes should be given due importance.

If by increasing the nodes and requests the performance remains stable, then and only then the system is considered scalable. This scenario was prevalent in traditional architecture. Scalability is termed as a function of performance. Today, it is reverse of the ratio and the scalability should be scaled up to achieve better performance results. To achieve better performance, computational cost should be subdivided. This approach should be applied on application layer as well as on data layer by sharing of database which enables distribution of the database and then ultimately the load on multiple nodes take care of managing specific portions data. If cache systems are used wisely at all levels, the performance of the architecture can be improved certainly.

MTTR instead of MTBF in Reliability

The reliability of architecture is measured with the concept of MTBF i.e. Mean time between failures. In other words, the reliability of a system depends upon how extensive the period is. However, this can’t be achieved because of commodity servers. In that sense to review the concept, connect reliability to resiliency. Cloud architecture is reliable when you achieve a lower MTTR which means Mean Time to Repair. If MTTR is zero or close to zero, this ensures that the organization has a reliable architecture and is resilient to any failure.

Capacity Planning in terms of Scale Unit Planning

In traditional architecture, capacity planning was designed in order to estimate the sizing which is needed to handle the maximum load so that the system has the capability to react proactively taking into consideration the worst situations as well. Resources are wasted for the most part of the system’s life cycle. On the other hand, in cloud architecture the capacity planning is enabled to regulate the scale unit that is scaling up and down of the load, well may be automatically.

Fundamental concepts of the architecture which are capacity planning, scalability, reliability, performance are profoundly revised.  We have witnessed how cloud architectures have diverged from everything established in past as it is inevitable to respond to changing scenarios. .  Two golden rules of properly designed cloud architecture are “Enable Scaling” and “Expect Failure”. Half success is already achieved if cloud architecture is well designed and implemented.

Importance of Website Uptime for Your Business

Comments off

Uptime is the context of web server working properly and all time without any failures. Uptime is the most important measure to check the maintenance and quality of web hosting servers. If your website is unavailable or is inaccessible then probably your web server is down.

Downtime can damage your business. The damage will vary depending upon your website. When small business website faces downtime for 20 minutes having just 3 to 4 web pages there is really not so big trouble. It is troublesome for bigger business having thousands of visitors and users every day. However, downtime generates negative publicity for both small and big organizations. Visitors are disappointed and leave to somewhere else thereby incurring a loss to organizations.

Reasons causing downtime

Web hosting server has many elements like operating systems, server hardware, network connections, database components and many other small elements. If any of the above-mentioned elements fail to function properly, it can cause shorter downtime or a prolonged one. To choose a right web hosting service provider, choose those companies which have more duplicated most fragile hardware parts, new servers having good uptime statistics than companies using old and obsolete servers.

Power supplies also can cause a downtime. As, most of the web hosting service provider suffered a loss in power causing a downtime for its users. Make sure to choose a web hosting provider which has uninterruptable power supplies.

Web hosting uptime is an important factor to check how reliable is your web hosting service provider and how frequently their servers are down. However, host.co.in is highly reliable and our customer service standing by to our commitments of delivering 99% uptime guarantee with 24×7 exuberant managed support services for 365 days a year.

DevOps Evaluation for Your Organization

Comments off

Today we are in a world where we are surrounded by cloud and DevOps. Implementing DevOps is not a simple task.  Before implementing DevOps, an assessment should be carried out which will clearly tell if the organization will benefit from the changes or no. Even if trivial incremental changes are witnessed with DevOps it signifies that organizations can test new ideas with more risks.

DevOps has been successful in speeding up software development and restructuring the involvement of quality assurance and operations teams.  Moreover, it enforces demands which every business must be capable enough to address.  Go through the below mentioned steps to undertake an accurate DevOps evaluation.

Is value added to the businesses with DevOps?

While implementing anything, make sure long term returns are considered. Traditional software development tools take more than considerable time for coding and testing before anything is perfect for distribution. However, challenges are faced in the form of oversights and a defect in the release not overlooking competition adversely affects the return on investment.

The complete picture of software development is changed by DevOps.  This is done by deploying shorter and smaller development cycles. Operations, quality assurance staff, developers relentlessly work on product’s constant release pipeline. Each and every release is a value addition to the characteristics and functionality of the product.  Sidestepping the risky investment period, it travels in market faster.

Is IT flexible enough to support DevOps?

The IT enterprise must install every small software release. That is, the new version of the software is installed on one or more servers in the cloud or data center and interlocking supporting storage, performance monitoring, databases as well as other resources. All these activities are core responsibilities of IT decision makers.

To deploy and provision a usual application which is done by following a traditional soiled process takes months and months of time. Specific requisitions, approval of new servers, application requirements, acquiring OS, installing any new system, acquiring software licenses’, performing the deployment of the approved system is determined by the IT organization.  While all this is carried out, there is very less interaction with the developers.

When IT employees work on rare software releases then such rigid processes work well.  A new development cycle should not be the only reason triggering the move to DevOps. While assessing DevOps, one should also consider how the IT team is functioning if sustained as-is and how it will change. IT people work closely with QA staff and developers in a different manner on DevOps to offer computing, networking and storage resources on a much faster pace to test each release.

Is the enterprise big enough for DevOps?

DevOps will function effectively only when a cyclical pipeline of development exists. If there are any gaps in the pipeline then it will leave the employees idle. To effectively deploy DevOps, the enterprise should be large enough to support the tools, processes that will enable DevOps to be productive. Balancing project demands and staff can initially be challenging for small enterprises. Application development is often sub contracted by small enterprises.

Maintaining and deploying a DevOps pipeline is done by large enterprises that has the capability to attain and adjust employee levels to achieve project timeline hassles. Organizations having 250 to 1000 employees are in a better position to deploy DevOps process. Organizations having more than 1000 employees will have the scaling ability to leverage DevOps strategy.

Is the organization aware about its DevOps strategy?

DevOps is not a single task. With single software you cannot successfully deploy DevOps. DevOps is an entire procedure of processes, tools and people. For effectively deploying DevOps you require clever developers, insistent testers and expert operations workforces. Collaboration, Workflow and automation with related tools are required. The organization must have flexible and dynamic business processes to completely eliminate traditional silos and multiple teams operating together. Having all these elements set in place, DevOps radically triggers deployment cycles and software development process bringing in tangible welfares.

The method of deploying DevOps varies as per different companies. Adjusting tools, people, processes to achieve organization’s goals. It means taking appointing developers who very well know DevOps cycles and workflows, deploying a suite of tools which will enhance the collaboration between QA, IT and developers and adopting business leadership which will drive DevOps deployment.

Will the company promise constant change?

Deploying DevOps is not a one-time activity. Organizations should not be resistant to change as deploying DevOps requires changing as per changes in business environment, technological advancements as well as changing user expectations. After making the initial DevOps step, new development language will be adopted, migration to another collaboration platform and DevOps workflow, upgrading servers, migrating to public cloud hosting or implementing a private cloud, getting familiar with business environments.

 

Is DevOps culture really important?

The three pillars of DevOps are process, technology and culture. More and more focus is given to culture because if culture is evolved, it will naturally support technology and process for its operations. For a successful Devops implementation, culture is really important. Difficulties will be faced while evolving an organization’s culture, but it’s worth it. However, many organizations believe that DevOps is not actionable, it is just automation, cultural change is not effective etc. This all is a misconception about the term DevOps. DevOps basically is collaboration between operations team and developers. DevOps is not at all concerned with technology, processes or culture but with DevOps, all these things can be improved.

A DevOps culture contributes significantly to the growth of the organization. Noteworthy contribution is made in the quality assurance area in information system which is a link between operations, development and customer support teams with clients. Moreover, it is advantageous in SMF- Service Management framework as more and more services rely on the collaboration between Dev and Ops members. Information System Development is one such area where major changes are witnessed reducing the gap between operations, developers and consumers enabling problem detection a bit earlier.

In short, Devops benefits supporting a culture of cooperation, supporting automation, enabling sharing, optimum usage of services, improvements in quality assurance and solving issues related to standards and structures.

DevOps is an ongoing concern which requires adjustments and optimizing resources. After assessing and following the above mentioned steps, carry out the process of deploying DevOps.

 

 

SSL Certificate for Security and Credibility of Your Website

Comments off

With the increasing trend of online shopping, online shoppers are very careful and want to be assured that their crucial information is safe. SSL certificate provides encryption of sensitive and crucial data like credit card and personal information. It also proves that your online website is trust worthy and reliable to your customers.

Why SSL certificate is important

E-commerce sites must have an SSL certificate. As an owner of an e-commerce site, it is inevitable for you to protect your customer’s sensitive information. SSL certificate acts as a shield and makes sure that information is not misused. If an inappropriate person somehow gets access to your customer’s credit card or debit card information, it will prove dangerous to you and create negative publicity of your brand. Your customers should know that their information is of prime importance to you and you are implementing solutions to protect them.

If you store credit card information on your database, you can process it using an offline POS machine or charge it manually on your merchant account’s website. For securing the credit card information which is transferred, you definitely need an SSL certificate.  You also need to be cautious with the data when it is stored on servers.

As long as it is not creating problems, you can opt for shared SSL certificate which web hosting providers give instead of buying your own SSL certificate. However, a shared SSL certificate will not provide 100% assurance to your customers regarding the security of their information. It doesn’t include your website or organization name in it and may give a warning.

If you want your own SSL certificate, you can own it. Many web hosting providers provide SSL certificate along with their other services. You will have to pay for having an SSL certificate.  But Host.co.in will not charge for an SSL certificate. Whether it is free or paid, SSL certificate is extremely important for your website to stand in the competitive environment.

Is Your Server Slowing Your Online Sales?

Comments off

Everyone hates a slow website. In fact, the latest studies proves that if a website takes any longer than 5 to 6 seconds to load, the normal Internet user will be closing the tab and looking elsewhere for their desired answer.

It will be like your potential customer leaving your site and going straight into the kitty of your competitors.

It is proved that once you lose such a customer, it will be very difficult for one to gain the trust again. If you are still ignoring this fact then this problem will become very nasty and difficult to fix, so here’s what you will have to do?

Choosing an appropriate hosting package for the size and type of business website that you are operating will take a lot of time for improving your website speed. It is true, there are numerous on-page fixes you can do too, like minimizing your CSS and image optimization, but the core of your website’s speed will be down to the kind of hosting package that you are using.

Personal WordPress blog and smaller sites can get away with a shared hosting plan. These plans are specially designed for smaller websites and personal blogs but make business owner make mistake of seeing the lower price rates.

However, making a decision such as this could eventually be disturbing it. Slow websites can eventually lead to customer loss, on the other hand shared hosting can also result in downtime too, means even if a customer was willing to continue they would not be able to access the website anyway. No website equals no sales.

What’s the answer?

While choosing a web hosting package it is crucial to go with the one which should suit your business requirements & will allow you to keep your site up and running all times. Big corporations that have the technical staff and budget can opt for their own dedicated server. Which will help them get a flexible and powerful way to serve their website to the public.

Smaller companies would have better option of VPS hosting which is a hybrid solution between shared and dedicated hosting.  These virtualization allows you to get the benefits of dedicated server without the cost or the technical headaches associated with them.

Host.co.in best Linux VPS hosting which allows these smaller businesses get a part of a server that is dedicated to them. They are free to run their own operating system if they want to and maintenance and updates are made simpler as they can restart their server every time they wish, giving them a complete flexibility.

Selecting the right web hosting provider and package will go a long way to improving your site’s load times. This is good news for your customers, and even better news for you. You will be able to see both improved sales figures and better ranking in search engine, as loading speed is a known ranking factor. So, ensure to double-check your hosting plans today, it could be the key to success you were looking for.

The Importance of VPS Hosting for WordPress

Comments off

The success of your marketing is supreme blogging. Writing a blog is all together a fun activity. Without it, you probably don’t have anything to promote on social media platforms, no interaction with your customers and leads, very few pages to convert your leads into hot clients and thus poor SEO. However, at the beginning it is difficult to arrive on a decision of choosing a free solution like WordPress, Blogger or going for paid solutions. If you are new to blogging, self-hosted option is a difficult choice to make. However, if you are having a long term vision of blogging, self-hosted option is the best option.

With shared-hosted, you can make whatever changes you feel like doing, make your WordPress site look like the way you want it, install or uninstall plugins as per your needs. You are the care taker for your WordPress site. You can control each and every aspect of your website. Before getting your hands dirty in blog writing, study the different hosting options for your blog.

Shared Hosting

Shared hosting is being a small part of a big server along with other websites and people who share the same server. Sometimes, hundreds of people share the same server. Larger websites gulp up too many resources affecting your website. Shared hosting is widely used by the newbies because it is simple, quick and most important it is cheap. That is what beginners choose but then later on it proves to be a big mistake. If you are planning for long term blogging then within some time you will get too big for shared hosting and you would like to migrate to a bigger host. But, people are not able to decide when they have grown too big for shared hosting. Here, you don’t need a deep study and analysis. If you are on shared hosting and your website is taking time to load then it’s time to shift to a bigger host. It is that easy. Shared hosting is like living in a college boardinghouse and having only one restroom. To use the restroom everyone has to get in line.

Virtual Private Server

Virtual Private Server is taking a portion of the building, having private access to your portion and without your portion no one can have access to your portion. VPS is a virtual private server which exists on a powerful server. People believe that a VPS is difficult to set up and is very expensive. This is not true. There are some companies that offer great services for as little as $6 a month. VPS server ensures assured allotment of resources which only you can access unlike shared hosting. In short, if there is a larger website on another VPS which is hosted on the same machine, you don’t need to worry about it as it is not going to affect the resources you consume. Assume that there is a big computer and many small computers are running inside it. If your VPS is not overloaded, your website will function properly. However, if you still feel your website needs something big you can easily upgrade your VPS to a dominant one within few minutes without migrating.

One such drawback of VPS is that you are wholly and solely responsible for the server. If anything goes wrong with something that is deployed on your server then your host will be of no help to you. That is why you will witness users taking back up of their WordPress site.

You don’t need to have technical knowledge to set up a WordPress site on a VPS. You can simply install a free and open source control pan-el such as Zpanel which will do all the hard work. You will have a great control panel that is web based which will help you to manage your website, email addresses etc. but which is very powerful than shared hosting

So, it seems that VPS hosting is better than shared hosting. Though you will face difficulties initially regarding setup and other things but it will be a savior for long term blogging and smooth functioning of the website.
