What is encryption?

The internet has transformed the way people live. It has changed everything from the way we learn to the way we shop. We use the internet to carry out a number of activities ranging from reading news, playing games and interacting with friends and family, besides a number of other things. We think that we only receive information from the internet; however, this is far from the truth. In the process of browsing the internet, we actually send out a lot of information such as our identity and location. We generally aren't as safe on the internet as we may think we are.

For instance, when shopping online, our name, address, and credit card information are transmitted over the internet to the vendor. With such private information being channeled through the internet, it is vital that certain measures be taken to ensure privacy and confidentiality of the data. Latest information technology news tells us that the number of cyber crimes is on the rise.

This is where encryption comes in. Simply put, encryption scrambles the data which is to be transmitted over the internet in a way that can only be decrypted by someone who has the encryption key.

The concept of encryption is based on cryptography, and it is of two types:

1. Public Key Encryption
2. Symmetric Key Encryption

Public Key Encryption

With this type of encryption, two different keys are used. There's a public key and there's a private key. For example, if a person wants to send encrypted data over the internet, the public key is used to encrypt the data; however, the data can only be encrypted by the recipient using their private key.

This method can be used to send secure emails and to digitally sign the documents. Secure Socket Layer (SSL) and its newer method, the Transport Layer Security (TLS), are examples of public key encryption systems.

Symmetric Key Encryption

In this method of encryption, both the sender and the receiver use the same encryption key. This simplifies the process and makes it faster. Nonetheless, the key and the data can be compromised while in transit over the internet. Data Encryption Standard (DES) was a type of symmetric key encryption that is replaced by a more modern Advanced Encryption Standard (AES).

Encryption of Data

The advantages of encryption aren't just limited to the internet; you can encrypt your data on your computer, your USB storage devices, hard drives, mobile devices and numerous other data storage devices in order to prevent misuse of data if your devices are lost or stolen.

Importance of Encryption

As learnt from the latest information technology news, the number of cyber crimes is on the rise and this makes it necessary for computer users to keep their data safe from hackers. Large corporations and governments require high levels of encryption in order to protect their sensitive plans such as business secrets and confidential data. It also gives us peace of mind that our data is not getting into the wrong hands.

How to make $75 an hour as a business consultant

magine what your life would look like if you could stop jumping from one marketing strategy to the next? Imagine how much more creativity, more content and more CONFIDENCE you would have if you had a simple, saleable skill that you could literally turn into perpetual piles of profit without breaking a sweat?

The truth is, if you are reading articles like this one, you probably already do.

The fact is, the VAST majority of online marketers fail to make money. They don't fail to make GREAT money... they fail to make ANY money at all.

Why?

Because many of us focus in the wrong places, and on the wrong processes to turn what we love, what we have PASSION for, into a profitable business.

For example, in my own business, the very FIRST money I ever earned was also the absolute easiest. (About 2K for selling a hyper local domain name with a simple WordPress blog - in a profitable real world niche, to an existing professional who had a practice in that field)

That followed months of trying just about every bright and shiny strategy under the sun, trying to sell ClickBank products to ebooks, to AdSense and just about every other approach in between.

Here are a few facts.

The average business coach, according to many independent studies, earns well over $150 an hour. (the ICF published a study just last year that was reprinted in many major newspapers that had the number at over $300/per hour)

In your LOCAL community, right now... there are tons of people who need help building BUZZ for their blog, brand and business. These are real people, with existing practices from design to dentistry, from credit counseling to clairvoyance, from accountants to aestheticians.

You can charge a flat hourly fee of $75... and be on the low end in our industry, or you can work on a contingency and earn a whole heck of a lot more as well.

All you need are a few clients who NEED what you know, and CAN'T do what you do, and your whole life can change in a jif.

You can build sites.

You can help them build relationships. (email marketing, social media marketing and otherwise)

You can help them create content.

You can help them raise money for their inspired ideas. (Crowdfunding consultants are HUGE right now)

You can do newsletter marketing. (using services like mailchimp to help your clients connect with THEIR communities)

You can build authority sites and sell ADVERTISING to your ideal audience.

You can build an authority site and write FEATURES on your ideal audience and charge big bucks for helping THEM build buzz for their brands... while building buzz for YOUR blog as well.

You can help them CREATE products and services. (this is a great opportunity for helping coaches and consultants CODIFY their content into a product, service or curriculum they can teach, preach, share or sell to their customers and clients)

You are only limited by your imagination and your inspiration.

The truth is, if you are struggling to sell something... I challenge you to BUILD something instead.

Stop chasing gimmicks and gurus.

They'll never get you where you want to be.

Instead...

Build something LOCAL where you live, and around what you love. It's a much more meaningful way to not only build your own business, it's a much easier way to contribute to your community as well.

Server managment guide

With a properly administered server management process, it is entirely possible to run multiple operating systems and several applications simultaneously. The process of improving efficiency has been slow and deliberate and many IT managers spend an inordinate amount of time deciding the most suitable route.

One growing area that shows a lot of potential is in the area of virtualization. Recent reports indicate that close to 50 % all severs in use, will make use of virtualization with the next 24 months. The enterprise scale operations are steadily moving to the fore when it comes to deployment of virtualized systems, but there are still some challenges that must be overcome.

Smaller operators are faced with the decision whether using outsource support service providers makes any sense, and even enterprise scaled business must appreciate the challenges that are involved. To the SME there may be multiple benefits to using outsourced support for IT functions, and in business environment, that involves more planning than processing, server management may be a bit more difficult to manage with physical servers.

There are number of different tasks involved with server management, and it is essential to have a plan in place, before any virtualization process in deployed in production the environment.

Virtualization introduces complexities when multiple systems must be patched, and there is no absolute certainty that patches are properly applied in virtual systems. Some of the bigger issues, when virtual server management is compare to managing physical machines, are the process of standardizing and following consistent patterns.

Virtualization may simplify deployment, as there is now support and ability to define operating parameters for the servers that handle the database and application operations. It is believed that accuracy is critical in the virtual environment, as there is often more potential for drift.

As a component of the server management process, focus must be placed on preventing drift with templates that detail the operating system, vendor software, patches, code and even architecture. New servers when introduced should remain consistent with the standard, and patches are also expected to fall in line.

One of the key issues involved in server management is perhaps performance. Outsourced support may provide some degree of exemption, but with complex virtual environments, finding root cause of performance issues becomes even more challenging.

There are a number of very useful tools available to assist and even automate some of the process of server management. It is possible to remotely monitor CPU and network resources using the right tools. Competency in the use various technologies for monitoring system events and compliance to operating parameters are beneficial.

Current technologies for deploying effective server management can provide multiple benefits even are a portion is derived from outsourced support services. You can get more information from server management services.
