Managed LAN Services is a commercial facility that delivers occupied controlling of the LAN and WLAN setup at your small branch workplaces as well as your big estates and data centers. LAN means Local Area Network. Some networks are small and some are big. Some network only shares information among themselves and some are connected the world. In our daily life, we all are connected by some kind of network. Some are short some are long. LAN, MAN, and WAN are the main types. But there are also other types of network. These networks help us to communicate with each other and make our life much easier.

Wide area network

Wide area network shortly known as WAN is a combination of many short local area networks and metropolitan area network. So many LAN (Local area network) interconnected with each other and become a WAN. In that case, you can say that the Internet is the largest WAN. In simple words, WAN connects more than one LAN and used for a large geographic area. It helps us to connect with one other. Without WAN, It may be not possible to connect the whole world together. It is a combination of so many devices like routers, modems, firewalls and so on and used IP/TCP protocol. Its range is more than a 100-kilometer network.

Managed LAN Services in Florida

Characteristics of WAN

  • Cover a large geographical area: It can cover as much as area as you want.
  • Unlimited expansion is possible: It has the capability for unlimited expansion.

Limitation of WAN

  • Complex to implement: As it’s a large network, it’s quite difficult to implement.
  • Security and reliability: Because it’s large network, there is a possibility of hacking our data.
  • High implementation cost: The initial cost for WAN is very high.
  • Complex administration: It’s quite difficult to maintain such a large network.

Metropolitan area network

Metropolitan area network is shortly known as MAN. More than one LAN is used to create a MAN. It is just like WAN but not as big as WAN. It is bigger than a LAN but smaller than a WAN. In short, it’s a medium range network.  Like WAN it is not owned by any single men or organization. It can be a size of a network of a city or in some cases, some universities have their own MAN. But those are a shorter range. In some cases, you can consider is as a bank network. Like a Bank network, where there are different sections. You can consider the sections as LAN. And all the employee of the bank interconnected with each other and perform as a single network like MAM. It has a radius of 30-40 kilometers/20-25 miles.

What is the wan network

WAN is wide area network. More than one MAN or LAN merged with each other to form a WAN. Wi-Fi routers, modems, and other devices connect LAN to WAN. WAN cannot be owned by any men or organization. But different companies or telecommunication companies take a lease for their commercial purpose. The Internet can be considered as the largest WAN.

LAN meaning

LAN meaning local area network. It is comparatively small. It may be limited to a single room or a building or maybe two or three building. LAN can be interconnected with each other by television or radio wave at any distance. So in these case, you can say distance doesn’t matter to connect a LAN.

Characteristics of LAN

  • Easy to implement: In LAN, it’s very easy to implement. Only two computer and router a hub and a Cay5 cable needed to start a LAN.
  • High-speed resources sharing: Can Share data at a very high speed.
  • Low implementation cost: very low cost needed to start this network connection.
  • Easy management: Easy to manage cause we have to manage a very limited area.

Limitation or LAN

  • Cover only a limited area: It can cover only a limited geographical area.

LAN connection

LAN meaning Local area connection. When a group of computers and their related devices connected with each other called LAN. It is smaller than MAN or WAN. Multiple LAN interconnected and created a MAN. Each LAN can be connected through television network or radio wave at any distance. A LAN can be built with a cheap hardware such as Computers, Hubs, Ethernet cables etc. A Small LAN could be a connection between two computers. But larger LAN may be a combination of thousands of computers. LANs are used to share data among themselves but not for the outside world. For example, think of an office building where everyone’s computer is connected by LAN and they share information through the servers.  LAN connection can be both wired and wireless. But the wireless connection is quite slow than the Ethernet cable connection. If a local area network is fully wireless then it could be called a wireless LAN in short WLAN. Its range can be around 1 kilometer or more.

LAN computer

LAN is local area network. It can be small or large. A small LAN maybe with a combination of two computers. But the large LAN could be a combination of thousands of computers. In this network, they shared their hard disk storages. In these case, the computers can share their information with each other. For example Cyber Café. In cyber café, hundreds of computer interconnected with each other with LAN.

Types of LAN

LAN can be two types:

  • Wire
  • Wireless

Wire: The LAN which is fully Ethernet cable based is called the Cable based LAN. In these case, the Computers are connected with Cat5 cables. High-speed data transfer can be possible with cable-based LAN.  Basically, in local area network, computers shared data with each other but does not make communication with outside world.

Wireless:  The network which is fully wireless is called wireless LAN network. These networks are mainly slow. These are also called WLAN or wireless local area network.

WAN, MAN, SAN, LAN, VPN these are similar kind of network.

LAN definition

LAN means local area network. Local Area Network is small. When multiple computers connected with each other and share their information with each other, is called Local Area Network. Its range can be in a room or a building or more. For example: In school, college and homes people set local network according to their customers need.

 So In this article, we see that common types of network and how they are interrelated.

To embark the cloud setup journey it is mandatory to understand the Cloud installation steps hence the implementation phase becomes smooth. The following discussion will cover the detailed scenario of cloud set up implementation which is applicable most medium and large organizations, especially for Florida. The steps of cloud installation art are discussed below so that after reviewing the discussion one can get clarified idea of how to set up a cloud computing environment properly to obtain the maximum benefits

Ø Assessment Phase

Assessment is the first step to consider for an organization while planning for Cloud installation. In this phase, organization evaluates its existing setup, workforce and other resources in respect to its IT portfolio. In the measurement of performance, availability, and scalability IT assets are judged and benchmarked. A cost-benefit analysis may be carried out to implement the planned Cloud installation. In this phase, An ROI model is suggested to develop as well as a standard level of strategy document should be prepared.

Ø Condensation Phase

Condensation or association is the next step of Cloud installation. All the association aspects of cloud set up like IT infrastructure and financial considerations must be investigated and executed. For instance, ifs firm comprises several data centers that are planning to shift cloud installation then the firm can close some of the centers and shift the data at the cloud location to meet the requirements of specific territory provided that it is mandatory requirement that the cloud infrastructure must have to store data centrally to fill out the necessities of all the data from different province.

Ø Virtualization Phase

Virtualization of IT infrastructure is the third most important issue of cloud installation. After consolidating IT assets; this particular step in the cloud installation process will assist optimization of consolidated infrastructure. In this step, the business must ascertain the extent to which hardware is underutilized so that hardware requirement can be meet efficiently as par the necessity of the hardware usage. Through this point, the organization can maximize the usage of the IT set up and use underutilized resources for cloud installation setup.

Ø Resettlement Phase

Function standardization

After completion of virtualization and consolidation of the data center, function standardization migration must be taken into consideration. From functional and non-functional perspective function must be evaluated and according to that selection or rejection for migration to the cloud is decided. Therefore it can be stated that function architecture standardization is a key issue to consider.

Function architecture standardization entails establishing the standard of the reference architecture, comparing it with the existing function architecture, finding the gap between benchmark scenarios and existing scenarios. At this phase, and figured out inconsistency has to be eliminated or modified as the requirement of the applications as required, to conform to the orientation cloud architecture.

Application performance

There are certain characteristics that are expected from virtualized cloud platform applications. For instance, if a specific URL and a specific path have been used to accesses a file by using the application then the cloud does not have any standard specific location of files because if the machine does not work the file will lose and the application will go down. In case of a cloud platform, it is not expected that application access file using an identical path, while the matching file can be located in several places on the cloud. Therefore the application needs to be modified such manner so that it doesn’t be expecting the file to be in a specific place.

Ø Automation Phase

In The automation phase of cloud setup journey, several wherein characteristics such as self-provisioning are incorporated in user applications. For instance, if an unexpected increase of load over a function goes up while it is running, conventional surroundings would demand procurement of a new server followed by installation and connection of the application to the network, for handling the additional load to the application. However, in a standard cloud setup, the application should contain the capability of self-scaling to form a new virtual machine (VM), install automatically in the virtual environment and start servicing the new demand.

Management and monitoring team may carry out the Automation as well. In case of system down or failure, an alert is received by the administrator automatically. In an Ideal case, the cloud set up is capable enough to create a new instance on its own and start the application as the requirement without manual intervention. Automation is self-healing and scaling enabled since it built into applications.

Ø Optimization Phase

The decision to move towards cloud setup is perpetually driven by potential cost and performance benefits. Optimization stage can be considered as final and inevitable phase since it sustains the analysis of the metrics. After the completion three months operations of the applications of cloud infrastructure installation, thorough observation on the generated metrics and evaluation must be performed to check whether targets are being met. Based on this analysis, necessary modifications can be incorporated to achieve the optimum benefit.

The prescribed steps in accumulation are the answer of how to build a cloud computing infrastructure and underground to obtain the highest maturity level of the cloud setup journey.

Virtualization offers several reimbursements since it encompasses the technological change in our industry that underpins the Cloud Computing wave. Along with Virtualization, physical server maintenance, energy cost reduces and implementation of solution availability put into practice. Therefore if any individual has appropriate idea how to install cloud computing in windows he/she is supposed to be understood how to set up cloud computing server at home.

The Requirements are–

  • A management tool that allows scrutinizing the servers that provide the virtualization services.
  • Secondly, an analytical tool that allows for being self-sufficient in requesting and managing their services simultaneously provide you with a method to calculate charge-back costs.

Windows Server 2008 R2 out-of-the-box provides some of the resolutions but does not provide all of these. For a complete resolution of management features one needs to add:-

  • System Center Virtual Machine Manager 2008 R2
  • System Center Virtual Machine Manager Self Service Portal

These Prescribed two arrangements provide the management, monitoring and self-service functionalities needed to run an effective cloud Service operation.

In summing up all the discussions it can be said that while taking Cloud Installation Services organizations or individuals need to be specific regarding some issues to get the optimum benefits like—

Ø  Deciding the expectations from a cloud set up.

Ø  Establish Realistic expectations.

Ø  Specify the organization work pressure and services.

Ø  Right Mapping of the virtualization process.

Ø  Recognize that standardization and automation go simultaneously.

Data Storage Security: Data storage security means different kinds of methods and settings which makes storage resources available to the authorized users and trustworthy networks and makes is unavailable to the other group of people. This kind of methods and settings can also be used for hardware, programming, communications and for organizational policy.

DATA SECURITY AND PROTECTION METHODS:

The importance of data storage methods is huge. In today’s world securing data has become a mammoth task. Data protection methods include encryption of data, traffic encryption and VPN, access control and user authorization, network monitoring, reporting and forensics and intrusion prevention system also.

Encryption of Data:

Encryption means changing the information in such a way so that it becomes unreadable for the common users except those possessing special knowledge (usually referred to as a “key”) as it allows them to change the data in a readable form. Encryption of data is necessary as it allows us to protect the data from those persons with whom we don’t want to share our data. In business it can be used to protect corporate secrets, governments can use it to secure classified with information, and many individuals use it to protect personal information to guard against things like identity theft. Approximately 78% people use this method to protect their data.

Encryption of folder can protect folder contents, which could contain emails, chat histories, tax information, credit card numbers, or any other sensitive information. In this way, even if your computer is stolen that data is safe.

Traffic encryption:

Traffic encryption is actually officially known as hypertext transfer protocol secure (HTTPS) which secures the conduction of information to and from a website. It ensures secure communication in a computer network and at present, it is widely used for internet security. In HTTPS, the communication protocol is encrypted by Transport Layer Security (TLS), or formerly, its predecessor, Secure Sockets Layer (SSL). The protocol is often referred to as HTTP over TLS or HTTP over SSL.

The prime motive behind HTTPS is verification of the accessed website and protection of the privacy and trustworthiness of the exchanged data. It protects against man-in-the-middle attacks. The bidirectional encryption of communications between a client and server protects against spying and tampering of the communication. In practice, this provides a reasonable promise that one can protect their data from imposition. About 60% people use this method to protect their data.

Access control and user authorization:

Authorization means such kind of security systems challenge you to prove you are the customer, user, or employee whom you claim to be, using a password, token, or other forms of testimonial. People are actually less familiar with the term authorization, they actually know it as access control. About 56% people use it to protect their valuable data.

Authentication verifies person’s identity and enables authorization. It decides what a person’s identity is allowed to do. For example, any student of a university can create and use an identity (e.g., a username) to log into that university’s online service but the university’s authorization policy must ensure that only you are authorized to access your individual account online once your identity is verified.

Network monitoring:

A network monitoring system generally keeps the track of the whole IT substructure with all devices and systems. Everything that uses a defined interface and delivers status information via standard protocol is controlled by administrators can monitor. The monitoring software must simply establish contact with the device or service using an IP address and can then retrieve the current device status. This helps the IT department to keep an eye on the status of every area in the IT infrastructure at all times. The main motive is to achieve supreme accessibility and finest performance in the network. To do this, the network monitoring system must cover three security-significant aspects which include monitoring the actual security systems, identifying unusual occurrences, and checking environmental parameters.

Apart from the above-mentioned methods intrusion prevention system, forensics, backup of data regularly can secure data which are valuable to us.

TYPES OF DATA SECURITY MEASURES:

Securing data should be a vital area of concern for every type of business owner. When one save all his business information for example clients contact, loss, gain, his bank account number in the computer then if anyone wants to harm his business he or she can simple hack his data. In this regard, data security should be everyone’s prime priority.

According to the most recent Verizon Data Breach Investigations Report, an estimated “285 million records were compromised in 2008.” And about 74 percent of those occurrences were from outside sources. Following are some data security measures which has been implemented for securing our data:

  1. Establish strong passwords

Keeping a strong password is one of the easiest measures which can protect our data.

A combination of capital and lower-case letters, numbers and symbols and make it 8 to 12 characters can make a strong password.

We should not use any kinds of a name which is related to our personal lives, for example, our own name, phone number, numbers of letters which comes one after another in the keyboard according to the Microsoft.

We should also follow that the length of the password remains long or medium.

As for how often you should change your password, we should change our passwords after every 90 days says Roland Cloutier, Chief Security Officer for ADP.

We need to make sure every individual has their own username and password for any login system, from desktops to your CMS. And finally, writing password anywhere can be a dangerous thing too.

  1. Put up a strong firewall

In order to make a protected network firewall is a must. It can protect our network by controlling internet traffic coming into and flowing out of your business

  1. Install antivirus protection

Antivirus and anti-malware software are essentials in your arsenal of online security weapons, as well. They actually work as the last line of defense Cloutier added.

  1. Update your programs regularly

It is important to update your apps and other software as new updated versions are more useful and they maintain more modern ways to protect our data.

“Your security applications are only as good as their most recent update,” Watchinski, Senior Director of the Vulnerability Research Team for Sourcefire explains. “While applications are not 100 percent fool-proof, it is important to regularly update these tools to help keep your users safe.”

Frequently updating programs keeps a person up-to-date on any recent issues or holes that programmers have fixed.

  1. Secure your laptops

As laptops are portable they are easier to steal or they can be lost easily. Encrypting our laptop in a proper manner is the easiest way to keep our data secure. Encryption software changes the way information looks on the hard drive so that, without the correct password, it can’t be read.

We must not keep our laptops in the car or any other place open so that the thief cannot take them. Even if necessary we need to lock them in the trunk.

  1. Secure your mobile phones

Smartphones hold many of our data, sometimes we keep our most valuable passwords, data and security methods. Smartphones also can be stolen easily so we need to keep them secure for our own safety.

The must-haves for mobile phones: Encryption software, password -protection Remote wiping enabled.

Remote wiping is “extremely effective,” Cloutier says, recounting the story of one executive who lost his Blackberry in an airport after he had been looking at the company’s quarterly financials. The exec called IT in a panic, and within 15 minutes they were able to completely wipe the phone.

  1. Backup regularly

Scheduling regular backups to an external hard drive, or in the cloud, is a painless way to ensure that all your data is stored safely.

The general rule of thumb for backups: servers should have a complete backup weekly, and incremental backups every night; personal computers should also be backed up completely every week, but you can do incremental backups every few days.

Getting your data compromised is painful so need to back up them for our own benefits.

  1. Monitor diligently

All the great technologies do not have any use if there is no one to keep them or practice them. One good monitoring tool. Data-leakage prevention software, which is set up at key network touch points to look for specific information coming out of your internal network. It can be configured to look for credit card numbers, pieces of code, or any bits of information relevant to your business that would indicate a breach.

IMPORTANCE OF DATA SECURITY:

The importance of data security is huge. Data are one of the most important parts of our lives. Our business, job all these things are related to data. So, if anyone steals our data they can simply ruin our lives.

 Encryption is significant because it allows you to securely protect data that you don’t want anyone else to have access to. Encryption can securely protect folder contents, which could contain emails, chat histories, tax information, credit card numbers, or any other sensitive information.

Everyone is worried about moving sensitive data to the cloud, and many organizations perceive that the cloud is not as safe as their own data center. Encryption of data helps us move to the Cloud safely.

Encryption of data helps us to achieve secure multi-tenancy in the cloud. If you encrypt data before it enters the cloud, and retain control of the encryption keys, you can ensure your data is safe, regardless of its neighbors. Hy-Trust Data Control provides the ability to encrypt the data in VMs before moving them to the cloud while you retain control of the encryption keys in your data center.

Lastly, it can be said that encryption is mandatory for our cause if we do not encrypt our data our personal information will be hacked and our life will be more disastrous. So, we need to save our data for our own betterment and for our own safety.
