by nithiyananthan Subakaran
Hi, you are landed on a good page for your search because i am also a person like you who searched for the same topic of learning online course short period of time ago. I spent so much of time to find most suitable place to study. After that i found a website called udemy. Many questions evolved from my mind about udemy like is udemy reputed to go , is it safe to pay money using credit/debit card, who will teach, quality of course materials , what is different between institute powerpoint slides notes. Finally i found everything about udemy. So let me say few things about udemy.

learn and teach online courses from home in srilanka and india:E-learning

Udemy is an online teach and learning marketplace so what does it mean, in udemy website students and lecturers can easily join by registering online form. Udemy only manages the whole tasks. For example payments between students and lecturers, conflicts and infrastructure. there are so many courses available now you can choose according to your needs, price, and reviews from other students that already enrolled for a particular course.

Test preparation- college entry,  international high school, grad entry exam, test taking skill.

Every course is being taught according to above main categories. When i was studying computer network and security in an institute sometimes point form powerpoint slides might be difficult to understand in home because that notes are actually made for lectures to explain the subject. and so many doubts would evolve if only studied that one . But after i enrolled udemy doubts were disappeared from me. Sometimes you might think that the youtube is best for learning using videos but that is not true at all because anyone can upload videos that may be deviated from academic standard and youtube's videos are not well structured to study.

Finally i recommended udemy platform to learn various courses from qualified lecturers. I have had personal experience with udemy. Register now and learn for discount price like me. And share your experience below comment section. Good luck.

Methods of Securing Hardware, Software and Data in Enterprises

by nithiyananthan Subakaran
In the age of the internet being all pervasive and data flowing freely between organizations and individuals, Hardware, Software and Data Security have become a pressing need for all growing organizations. To get things started for your company has listed an approach to Security that can be implemented on various levels at IT Company:
computer security

Hardware Security

The first line of defense against theft should be for company hardware, since physical theft is the most common and recurring of company property theft.

a. CCTV Cameras

The most obvious time-tested option here would be to employ CCTV cameras in all areas of the office where devices with proprietary data are located. The IT companies will have to install compact ceiling mounted cameras which are inconspicuous which should cover all active areas of the office. The only limitation to this is the initial investment and the continuing investment in security staff to monitor live video feed.

The cameras can be fitted with motion sensors in regions of low activity to save on power and monitoring need. (Howell, 2016)

b. High Precision Motion Sensors Coupled with Night Vision Cameras

Places in an organization which have hyper sensitive information stored in purely physical or hardcopy form such as defense project blueprints, or bank Deposit vaults you will need a soaped up version of the first option that is linked to alarms and automated doors that slam shut in case a highly monitored zone registers unwarranted movement. Motion Sensing Night Vision Cameras linked to alarm systems, and automated steel doors that snap shut may be the answer here. Or motion sensing laser system can be used. (Howell, 2016)

c. High Impact Low Investment Visible Deterrents

Once the first two options are covered the company will have to get down to the specific devices for security measures. A simple act of putting up a sticker that says “ Do not Tamper: Traceable Device” will deter many wannabe data bandits. The company can put such stickers on key points on a laptop or a desktop. Services such as Immobilize (RFID tag) help you mark and display protected property. (Howell, 2016)

d. Invisible Tagging

Companies such as Retain guard and Smart Water help you tag your electronic items such as a Laptop, Tablet, smartphone or PC with a permanent unmovable tag or an invisible ink to tag the item of your choice. Post theft it can be tracked easily to retrieve the said item. (Howell, 2016)

e. Multi-layered Hardware Protection

An office environment can have zones of varying vulnerability to theft and intentional damage to data. In this case it is best to employ a variation of all the methods specified above to ensure maximum safety. The CCTV can be employed throughout the office campus since its working mechanism is pretty straightforward. In places where security is completely beyond compromise, with the fate of the company hanging on the said physical storage of data, Motion sensors coupled with night vision cameras and steel doors can be employed for security.

While inside the office working environment where it is tough to oversee every single interaction in terms of hardware exchange, you can use visible deterrents such as Immobilize RFID tags to fend off low level threats to theft.

For the more persistent thieves you can combine visible deterrents with invisible tags to see that the thefts can be tracked down and brought to light! (Howell, 2016)

Software Security

The software that your company uses is the foundation on which your business runs and on which your customer data is stored. The company will need to look into this as the most important thing on your to do list after Hardware Security.

a. Thou shalt not fail to Update and Upgrade! , finding and fixing bugs

This is the holiest of all Software Security Commandments! Since the software of an IT organization is the backbone of their electronic resources, the company will need to see to it that it is are on top of any updates or patches of the software tool that it is using, and will install it instantly. The company’s business depends on it. Not only do software upgrades increase the speed of your business, they see to it that any holes in software security aren’t exposed to interested parties, whoever they may be.

Large companies see to it that their IT admin teams take over this aspect of updating and upgrading all software’s even remotely related to the business. They work on the off-shift timings to install updates and clear system bugs and see to it that the core software’s run smoothly.

Smaller companies may not have the resources to hire large admin teams to see the regular updates are done on time. As an alternative, scanner software’s can be installed which check for updates and inform the employees so that they can install the software patches themselves.
(MacGraw, 2011)

b. Install paid Antivirus software’s

The other major way a company can ensure software security and prevent additional bugs in your program software’s is to install paid antivirus software to prevent internet security threats that eat into your processing power and corrupt system files. Free antivirus software just does not pack enough punch as much as the paid versions and even small businesses can afford the cost of such software’s. (MacGraw, 2011)

c. Add Company Specific Firewalls

No matter how small a company’s IT admin team is, it can always ask the team to develop and add custom firewalls (Software restrictions) to see that your core company software is being used the way it is supposed to. If this step is done right, it will prevent unauthorized logins, usage, and streamline the usage of software resources in your IT Company. For example if someone is hogging internet bandwidth by using domestic applications while a critical business deliverable upload is going on, the IT admin can script specific application specific firewall to see business data uploads are not hindered. (MacGraw, 2011)

Securing Sensitive Data

This is no easy task and it involves locking up all your crucial business data in layers of software security along with dedicated processing power to ensure continued protection.

a. Decide Which Data is Important

Encryption at this level is highly complicated and even expensive therefore the first thing you have to do is sort out the business data which is worthy of high level encryption and data protection. This will leave you with more resources to offer better data protection (Data security handbook, 2008)

b. Manage Passwords and user account with different access control effectively

Passwords are the first line of defense against data theft. Generating and managing them can get cumbersome if they have to be changed regularly. A company can do these using services such as Last Pass which help create and manage passwords for users. Use a paid version. (Data security handbook, 2008)

c. Train the Employees on Data Security

The best tool to avoid data theft is to prevent it, by training the workforce. Organize team meetings, webcasts or even email blasts, whatever works best for your organizations size and scale. But a company get across to its employees the best practices adopted by the company for data security have to be adhered to. Empower your employees, Cut the problem at the root! (Data security handbook, 2008)

d. Encryption

Encryption is the act of scrambling and coding data beyond its conventional use to make it meaningless to an outsider without the encryption passkeys. Services such as True Crypt help you encrypt an entire Hard Drive or even a USB drive to make sure a company uses only encrypted data which only it has access to.

SSL encryption or Socket Service Level Encryption for Webpages is a novel way of making sure your online content isn’t being hacked an external entity.

Before you start deciding on encryption first weigh the advantages and the cost side by side so that the organization doesn’t lose more than it gains, as a business. (Data security handbook, 2008)

e. Antivirus Software’s

These also play a huge role in keeping Trojan programs from the net and other viruses from hijacking or corrupting your data beyond recognition. Moderation is key here, if this is done beyond a certain extent it may actually slow down your business processes. Hence always match your antivirus software with your organizations computing power to get the best fit and results. (Data security handbook, 2008)

f. Network traffic monitoring

When it comes to ip traffic monitoring it’s a must to implemented if the company dealing with sensitive data. Most popular free ip traffic monitor software is wire shark it’s built-in with kali Linux, which is the best operating system for vulnerability penetration test. (Data security handbook, 2008)


The guidelines specified here are hugely comprehensive and highly contingent upon the size and resources of the organization. Each method stated here has to be chosen after weighing the pros and cons according the resources available in the organization against the Security need and the investment that can be made for the same. For example if the organization in question is an MNC it can encrypt large amounts of data without thinking twice about implementation cost. In small organizations data encryption and even and software upgrades have to thought upon, planned and executed based on the availability of funds.

But since this is a holistic guide to organizational security even slivers of the said guidelines can be taken out of selective context to design effective levels of security for the said organization in Hardware, Software and Sensitive Data. And organizations irrespective of size and access to funds can refer to the said suggestions to optimize existing security infrastructure and reap a higher bottom line.

Uber Apps Service Alternatives to India and Pakistan

by Rajesh Raj
Taxis have long been used as one of the primary modes of transportation in cities to get from Point A to Point B, and one of the most popular innovations of the traditional taxi grab have been an upgrade to what are called transportation apps’, in which consumers can use an app on their smart phones to request transportation from drivers who use their own vehicles.

Uber has easily been the most successful app transportation service and has successfully challenged traditional modes of city transportation. But even though Uber is currently available in over sixty countries and four hundred cities across the globe, it is not at all your only option in this market.

In fact, competition to Uber has sprung up in all corners of the world, including in major Asian markets such as India and Pakistan. Let’s look at some of the most viable alternatives to Uber in these two countries:

Uber Apps service  Alternatives to India and Pakistan

Ola Cabs

Ola Cabs is easily the biggest competitor to Uber in India. The reason why is because Ola commands a vast fleet of cars in over eighty different Indian cities, and also manage to offer prices that are far less than Uber. You might think that this decrease in price translates to a decreased quality in the cars for transportation, but this is simply not true. All drivers with Ola Cabs are verified and their vehicles carefully inspected for both safety and cleanliness.

 Easy Taxi

Easy Taxi is another significant competitor for Uber, offering services in over thirty different countries and four hundred cities, with over four hundred thousand taxi drivers spread across those cities. One of those countries is India. Easy Taxi provides features such as the estimated arrival time for your drive as a fare calculator for your destination, along with a number of vouchers and coupons that are redeemable on your phone. All drivers for Easy Taxi are screened and cars checked for safety.

Albayrak Taxi (A-Taxi)

Albayrak Taxi (also known as A-Taxi) is one of the most viable alternatives to Uber in the country of Pakistan. They offer a simple fare of just Rs 120 for every thirty five kilometers, and offer both taxi and rent-a-car services. All cars under A-Taxi are air conditioned, monitored for twenty four hours, and driven by fully trained drivers.


 Careem is a Dubai-based chauffeur cab company who have more recently expanded their operations into Pakistan, specifically into the cities of Lahore, Islamabad, and Karachi. They have come into direct competition with Uber as a result. They offer four different kinds of cars for transportation: business, economy, max, and even transportation for children.


As you can see, there are plenty of reputable transportation alternatives to Uber in the countries of India and Pakistan. Since there is plenty of room to grow in the app transportation market, you can also expect even more transportation companies like Ola Cabs or Careem to appear in India and Pakistan and expand as well.

10 Paypal Alternatives for Indian Freelancers and Bloggers

by Rajesh Raj
PayPal is a popular and leading payment gateway option for freelancers through out the world. This is because of its ease to set up and it easily integrates with other websites. This makes it the most convenient online transaction system that freelancers can use. However, Indian freelancers cannot use PayPal the same way as other users from countries like Australia, U.S.A U.K etc. This is because of the PayPal and R.B.I disputes. As a result it is important for them to find an alternative site to PayPal that are cost effective to help them get payment from international and Indian buyers.

10 Paypal Alternatives for Indian Freelancers and Bloggers

Highlighted below is a list of alternative sites that Indian freelancers can use. They are similar to PayPal but have fewer or more features.

1. Alertpay

It is the fastest growing e-currency website and allows transactions in 190 countries. It is similar to PayPal as you can accept payment to your service through it, store your money in it and use it to buy stuff online. Its verification is easy as you can verify your alert pay by verifying your credit card or through bank verification. Withdrawing money to your bank is easy and fast. It charges a low fee for transactions.

2. 2checkout.com

It has existed for more than ten years and provides a fast and flexible payment option. I t is also a great alternative to PayPal and is used to collect payment from all over the world. It charges a one time setup fee of $49. Its only downside is a high transaction and transfer fees.

3. Skrill

This is also a popular alternative to PayPal as it is easy to set up. It also charges low currency conversion rates.

4. PaisaPay

This online payment system only work with eBay. eBay is the biggest e-commerce website on the internet. It allows buyers to pay sellers through debit or credit cards. It runs exclusively on Indian banking and credit card infrastructure. It does not impose any transfer limit on transaction.

5. Payoneer

It is the oldest service for global payment. It allows you to receive money from European countries the U.S. Its transaction fees are very low. It is free to sign up and after transacting over $100 you get a bonus of $25.

6. Zilra.co

This is an alternative for Indian users who receive payment from clients from U.S.A. No transaction fee or currency transaction fee is charged, They only charge $25 per withdrawal.

7. PayZa

This is another great alternative to PayPal. It is in fact better compared to PayPal in many ways like:
It offers a prepaid card ATM.
It accepts payment and withdrawals using bitcoin.
It is free to set up and has an android app.

8. Transferwise

It has a low transfer fee and low transfer charges. It was created by the skype team and backed up by Richard Branson.

9. Paymate. 

The great thing about paymate is that one is not required to have a bank account to open an account with them. It is only in a few countries, India included.

10. Google checkout

This is one of the safest and secure alternative to PayPal. It is new in the market and that is why it is still not popular.
