Point to Site (P2S VPN Connection Between Azure & On-Premises

Introduction to Point to Site VPN Azure
A Point-to–Site (P2S VPN) connection allows you to establish a secure connection tunnel to your virtual networks (VNet) using a single client computer device. P2S VPN can be established by initiating it on the client’s computer device. This is a good option for WFH employees who need to connect to Azure VNets remotely. When you only have a few clients who want to connect to a VNet, P2S VPN can be used in lieu of S2S VPN.

Export and create certificates
To create client and root certificates, open PowerShell. To create a root certificate, run the following PowerShell script. Once created will be installed in the user certificate app$cert = New-SelfSignedCertificate -Type Custom -KeySpec Signature `-Subject “CN=RootCert” -KeyExportPolicy Exportable `-HashAlgorithm sha256 -KeyLength 2048 `-CertStoreLocation “Cert:\CurrentUser\My” -KeyUsageProperty Sign -KeyUsage CertSign1234$cert = New-SelfSignedCertificate -Type Custom -KeySpec Signature `-Subject “CN=RootCert” -KeyExportPolicy Exportable `-HashAlgorithm sha256 -KeyLength 2048 `-CertStoreLocation “Cert:\CurrentUser\My” -KeyUsageProperty Sign -KeyUsage CertSign
Now, we need to create a certificate for our client. The following script can be executed in PowerShell. The below script will create a ChildCert certificate and install it in the user certificate app.New-SelfSignedCertificate -Type Custom -DnsName P2SChildCert -KeySpec Signature `-Subject “CN=P2SChildCert” -KeyExportPolicy Exportable `-HashAlgorithm sha256 -KeyLength 2048 `-CertStoreLocation “Cert:\CurrentUser\My” `-Signer $cert -TextExtension @(“”)12345New-SelfSignedCertificate -Type Custom -DnsName P2SChildCert -KeySpec Signature `-Subject “CN=P2SChildCert” -KeyExportPolicy Exportable `-HashAlgorithm sha256 -KeyLength 2048 `-CertStoreLocation “Cert:\CurrentUser\My” `-Signer $cert -TextExtension @(“”)
We now need to export the certificates for further use. Win+R. Open msc and search for Manage user certs. Right-click on root cert inside certmgr console. Click on Export
Select No, do not export your private key in the Export dialog box and click on Next
In the export file format dialogue box, select Base-64 encoded (X.509(.CER).
To save the certificate on your computer, click Finish after you have completed the Certificate Export Wizard.
Export the client certificate by following the same procedure, except that you will now need to select option Yes to export the private key.
Keep the default option in the Export File Format dialog box as shown in the screenshot below, and click Next
Under Security dialogue box, enter a password to protect the pfx file and set the encryption type to default. Click on Finish to save the file name in the File to Format dialogue box.

Where did THAT project come from?

You are about to lead another project kickoff meeting. You know what your team is supposed to do, but do you understand why? You are not the only one who isn’t sure. Too often, we are given projects to lead but not given any background information about why this project is important. This hinders your ability to inspire and set the vision for your team. It is not your intention to say, “Because management says so.?” Management is your job too. You are. Your project portfolio management process is the key to finding out the answer. You want to understand how projects are selected and suggested for your company. You will be able explain why this project is important to you.
The process of selecting projects will vary from one company to another and from one industry to the next. Despite this, there are common themes that should be part a project portfolio management process or project selection process. A standard selection process should be used to select project ideas. This process should be structured in a way that can objectively evaluate the efforts of your company.
Let’s start at the top. If your company has a clear mission and you understand what you do, you are already ahead of the game. You are already ahead in the game. With the mission in mind, what are your company’s goals for the next one, five, and ten year periods? These goals should be the focus of the projects chosen. The goal must be clear. It is not enough to increase our customer base by 15%, and have at minimum 50% of our customers purchase at least $50,000 worth goods each year. This is better. When someone suggests a project, it should be evaluated on its ability to increase our customer base by at least 15% and have at minimum 50% of our customers buy goods worth $50,000 each year from us.
Every project does not have to be about growth. Your company has a portfolio. This portfolio includes projects that help you achieve different goals. Your organization’s project portfolio should be designed to provide maximum performance, just like a financial portfolio that is tailored to meet specific investor needs. There will be projects that must be completed to meet regulatory requirements, to improve operations, to be more competitive, or to strengthen your brand.
Ideas for projects don’t just come from the top. Anyone can offer suggestions. Even someone new to your company might have some fresh ideas. They might also suggest ideas that aren’t quite right. You can really benefit from different perspectives when you have a process for selecting projects that allows everyone to offer suggestions and is reviewed by the right people.
The best projects will be chosen if there is a process in place. If each project has a priority then everyone will know why this project is important and why it is important now.

When to Use 20mhz Vs 40mhz Vs 80mhz

Everyone, from home users to large corporations, is responsible for improving and managing Wi-Fi performance. Wi-Fi performance is affected by channel width. The width you choose can make a big difference in Wi-Fi performance. It’s not always easy to get it right. It can be difficult to keep up with best practices when there are multiple standards and many tradeoffs.
Every wireless environment is unique and you must adapt your equipment to suit the conditions. It is often not worth increasing your channel width with 2.4 GHz. Instead, you should keep it at 20 MHz. With 5 GHz, however, increasing channel width can increase performance, but there are tradeoffs. If you don’t have interference concerns and all of your clients support 5 GHz, choose the widest width possible.
This video shows how SPOTO trainer Keith Barker uses NetSpots and SweetSpots as a way to optimize Wi-Fi. He maps his coverage and examines channels for possible interference.

Learn how to become a security expert with SPOTO’s Cybersecurity Training
Start training The right answer to this question, like most things in tech depends on the context. To help you better understand the topic, let’s look at the “why” behind these generalizations.
Understanding Wi-Fi Bands
It is crucial to understand Wi-Fi bands in order to know when to use 20 MHz, 40 MHz, or 80 MHz channel widths. It is also a prerequisite for understanding Wi-Fi channels, channel widths, and channels.
The main Wi-Fi bands are 2.4 GHz & 5 GHz. These Wi-Fi bands can then be divided into channels that wireless devices can use to communicate.
2.4 GHz Wi-Fi Band
The 2.4 GHz band covers a 100 MHz frequency range of 2400 MHz up to 2500 MHz (equivalent in size to 2.4 GHz and 2.5 GHz). The 2.4GHz band is divided into 14 channels each of 20 MHz (more information on other channel sizes later).

Source: Wikimedia
You can see that there are 14 channels within the 2.4 GHz band in the image. Channels 1, 6, 11 and 14 don’t overlap.
You’ll quickly realize that 14 bands of 20MHz equal 180 Mhz if you do the math. This is more than the 100 MHz band of 2.4 GHz, which means that the channels overlap.
This is important because overlapped Wi-Fi channels can cause interference. There are four 20 MHz channels available for Wi-Fi at 2.4 GHz: 1, 6, 11, 14, and 14. Not all channels may be available in every location due to different regulations. In the United States, for example, there are only 11 channels.
5 GHz Wi-Fi Band
The Wi-Fi band 5 GHz covers 150 MHz, ranging from 5.725 to 5.875GHz. The range of Unlicensed national information infrastructure (UNII) bands extends the range to 750 MHz. There are 24 channels that are non-overlapping within the 5GHz band, using 20 MHz. This is just a generalization. Channels available will vary depending on where they are located and how large they are.
2.4 GHz vs. 5 GHz: Popularity and interference, throughput and range
While 2.4 GHz is currently more popular than 5 GHz, both are widely used. It is easier to implement 2.4 GHz than its 5GHz counterpart, so manufacturers can take advantage of it to cut costs. 2.4 GHz is also more widely used than its 5 GHz counterpart, so there are many more 2.4 GHz devices.
However, this popularity has its downsides. Network congestion can be exacerbated by the high number of 2.4GHz devices and the limited number of channels that are not overlapping with 2.4GHz.
Many consumer devices, including cordless phones and microwaves use the 2.4 GHz frequency band. Interference is more common in the 2.4 GHz band. It is less vulnerable to interference because of the large number of channels that are not overlapping on 5 GHz Wi Fi.
Which is better: 2.4 GHz or 5 GHz?
To optimize for dist, 2.4 GHz is the best frequency in most cases.

When to hire the first project manager

It’s you, the founder, and maybe a few employees when you start a business. While you do most of the work, projects are not so complex that you need one. But once you have more employees and start to have larger projects, you will need a dedicated project manger. It’s too late when it hurts (at least when you think about hiring a project manager). Matt Weinberg, from Vector Media Group, discusses in Bootstrapped episode 72 that his company hired their first dedicated project manager when they had more employees than 10, but wishes they had done it sooner: “We hired our first dedicated manager when we had 12-13 people or something. It was too late, it was super late. It was something we should have done earlier. We did it because we were wasting a lot of money on projects and didn’t have good management.” – Matt Weinberg President at Vector Media Group Inc.
As your company grows, so does the way you run it. You must anticipate what the next stage will bring and how to handle them. You will then be able to plan, prepare, identify new job opportunities, how to manage resources, and how to handle challenges. Stage 1Companies typically start as a partnership with one or two founders. The company is focused on one thing, such as developing Magento e-commerce websites. It is not profitable to hire a project manger so early. The number of employees is 5. This is the right time to start looking into a project manager in order to be prepared for the next stage. This is your chance learn how to work with a manager and let go managing everything yourself. Stage 3: The company gains more clients who keep coming back. The company diversifies its services to win more large projects. It also starts developing Magento websites. It is now a full-service agency, which does everything (design, development, branding, digital marketing, etc). This results in more employees, a new layer of middle management, and solid processes. The number of employees varies from 10-20. You should have at least two project managers by now. You have more hierarchical layers, provide more services, and you have a lot of clients who keep you on their retainer. Founders don’t code anymore. Instead, they focus on managing, finance, and pitching clients. Stage 5: Once you have over 50 employees, your company is a large consultancy that does everything and has multiple locations. At this stage, the company’s top concern is keeping employees happy and hiring. Founders don’t deal with employees anymore, but focus on company culture, strategy and market positioning, building relationships with large clients, etc. Why it’s important to hire a project manger early
It’s best to hire your first project manager in the late stage of development when you have approximately 7 employees. Even though it may cost you more in the long-term, you will be able to show clients your portfolio and clients will be more trusting you. This will lead to more.

What your project team isn’t telling you

Today was my first chapter function for PMI. It was too late for networking and mingling, but I met some great people who I look forward to interacting with again. Timothy Johnson, Carpe Factum, was the guest speaker. His presentation was titled “What is your project team not telling you?”
Tim is a great speaker. He had us laughing and very engaged. He spoke extensively about the political aspects of project teams, as well as the organizations and stakeholders involved. He shared many great tips and accurately described most project environments. He also spoke briefly about his book “Race Through the Forest”. It’s a project manager fable. Project managers now have one of these business fables!
After Tim’s presentation, I spoke briefly with him and he shared some information about his blog, CarpeFactum.com. I have read a few of his posts and it seems he is very interested in organizational behavior, politics, and the pursuit of achievement. I saw him quote Stephen Covey, so that’s a win in my book. I subscribed to his RSS feed in order to keep up with his blog.
Tim stated that he would make the presentation he used today accessible to the Sioux Empire PMI Chapter. I will post a link to it on this blog when they post it. There is some amazing content there.
What does Carpe Factum actually mean? It means “Seize the Accomplishment” in Latin. Tim jokingly said it today: “It’s Latin means, ‘get’er done!

Strategic Capabilities and Resources for an IT Business: Use them now!

IT companies’ primary goal is to provide services for their customers. If these services are to be successful, they must be valuable for the customer. It must be useful and available to customers at all times. IT service providers cannot offer value-adding services without effectively managing their strategic capabilities and resources. An organization that fails to manage its strategic capabilities and resources can’t create value for its customers. This can have a negative impact on the organization’s ability generate revenue and sales. What are the ITIL foundation training’s strategic capabilities and resources for an IT organization? Let’s take a look at Strategic Capabilities and Resources for an IT Business.

Strategic Capabilities and Resources for an IT Business
First, let’s review the ITIL definitions for capabilities, resources, assets and IT organizational structures. Understanding the differences between these three components will help you to understand how they can be used in order to create value for your customers.
Strategic resources
ITIL online courses define resource as any term that refers to IT infrastructure, people, money, or anything else that may be useful in delivering an IT Service. Strategic capabilities and strategic resources are different because you can purchase or acquire resources with a budget. Resources are therefore tangible assets for an organization.
The following are strategic resources in an IT organization:
Financial capital

Strategic capabilities
Strategic capabilities are the ability of an organization, person or process to perform an activity. Strategic capabilities are intangible assets that an organization has. This means that you can’t buy a capability with your financial resources. The following are the strategic capabilities of an organisation:

Let’s suppose that your company hires a highly skilled manager from another company. The company’s management and organization structure are not mature enough for the skilled manager to make any changes. The output of a company will not be as good as it could be if there is not enough strategic capability to use the resources. To produce good results, resources must be used efficiently and with the support of sufficient strategic capabilities. Even though a company may have enough resources, it won’t produce successful outputs if it doesn’t have the necessary strategic capabilities to manage them.

Service asset
A Service Asset is any capability, resource or ability of a Service Provider. If you look at the word “asset”, it is the designation or use of any resource or capability. Anything that can contribute to the delivery or provision of a service is considered an asset of a service provider. This perspective shows that all the strategic capabilities and resources of an organization are essential to the delivery services to customers. All of an organization’s strategic capabilities and resources are therefore assets.
When creating an IT strategy, it is important to consider the capabilities, resources, assets, and capabilities of the organization during the Service Strategy stage. A new service cannot be launched and successfully operated without the right strategic capabilities, resources, or assets.
How do services delivery affect strategic capabilities?
The capabilities of an organisation coordinate, control, deploy, and control resources. With the help of its strategic capabilities, an organization creates products and services that create value for customers. Th

SLA Management: How can you improve ITIL Service Level Targets

Service Level Agreements (SLAs), which are part of the ITIL framework, are the contracts between an IT service provider provider and its customer. These service level targets set service quality standards to ensure that the IT service provider will provide the best service. SLA management is crucial to ensure that these SLAs remain current and that the agreed performance standards are met. This is the role and responsibilities of SLA management in ITIL, as described in ITIL foundation training or other online ITIL courses. SLA management is part of the larger theme of service level management.

Service level targets reviewed
SLA management should closely monitor services provided in a live environment to ensure that they meet the service level targets. SLAs are formulated to clearly define the service level targets that must be met by the IT service provider. SLA management ensures that SLAs are kept current. To do this, it is important to review service achievements and hold periodic review meetings with customers. These SLA management meetings analyze the performance of each service provided to customers and check if they have met the service level targets as set out in the SLAs.
Sometimes it is impossible to achieve the service level targets due to market changes or capacity constraints. A service level review can establish that service level targets were not met. However, it is not possible to immediately pinpoint the cause. Only proper root cause analysis can pinpoint the source of pain. Although it may seem like there is a problem with the breach, root cause analysis can help identify the real problem. This could be something that no one on the team had considered initially. SLA management must identify the root cause of problems in order to achieve service level targets.

Root Cause Analysis
If it is determined that a service cannot meet its service level targets through SLA management, appropriate action must been taken by the customer and/or the IT service provider. These actions must be documented. If a service fails to meet its 98% availability target, it is important to determine the cause and find the root cause. Root cause analysis of breaches of services is an important part of SLA management.

Each breach of service level should be addressed in SLA management. This will allow you to pinpoint the cause and prevent future incidents. If the supplier is responsible for the breach of the service availability target, then the SLA management phase must include actions on either the supplier or partner. If the root cause of the breach was a failure of the servers that provide this service, then strengthening these servers should be taken to prevent future breaches.
Both the IT service provider as well as the customer are responsible for SLA management. Each breach of the service levels targets must be analyzed to determine the root cause. Then, the appropriate actions must taken to prevent future breaches and ensure that customers receive the service they expect.
It is crucial that corrective actions are based on a thorough root cause analysis, not just what the team thinks has gone wrong. A proper root cause analysis will ensure that the problem is fixed. It is not possible to solve a problem by ignoring the root cause. This can lead to financial loss and indirect sales losses.

Six Sigma: What is the Normal Distribution Curve of Six Sigma?

Six Sigma is a data-driven approach for problem-solving. Six Sigma involves many mathematical and statistical concepts, such as the normal distribution curve. Lean Six Sigma courses cover the most important statistical concepts needed to solve problems according 6 sigma rules. Six Sigma principles are heavily based on understanding the normal distribution curve, as briefly explained in the free online Six Sigma courses. Let’s take a look at the normal distribution curve.
What is the normal distribution curve of data?
The mathematical concept of normal distribution, also known as Gaussian distribution, is sometimes called “Normal Distribution Curve” (or “Bell Curve”) and used to describe it. It is the shape created when a line is drawn using data points that correspond to the criteria of “Normal Distribution”.
Participate in our 100% online and self-paced Six Sigma training.

Natural phenomena follow a normal distribution curve
Many natural phenomena exhibit a pattern known as the ‘Normal Distribution Curve or ‘Bell Curve. The results of measuring the height of women around the world will look like a bell if you take the measurements. This pattern also applies to temperature. If you measured the average July day temperature in the US each year, the bell curve pattern would be apparent. You can also measure the heights of your coworkers at work or how long they take to brew a cup of tea. This will give you an approximate normal distribution curve.
The structure of a normal distributions curve
Let’s take a look at the structure and function of a normal distribution curve. The center is the point at which the most data points are found. It would also be the highest point of the arc. This point is also known as the average or mean of the normal distribution curve. Let’s take the example of height. There will be more women of average height than other heights, so the normal distribution curve will have the highest value for women worldwide.

The normal distribution curve’s mean, median, or mode.
In the case of normally distributed data, both the median (or the mode) will equal the mean. Let’s look at the difference between mode, median, and mean. The mean is the sum total of all data points divided by the number. The median is the average value if you add all the values, from the smallest to the largest. The mode, on the other hand, is the number that appears the most often in a collection of data points. Normal distributions will have the mean, median, and mode all being the same.
Outliers in a normal distribution
The normal distribution curve has a concentrated center and decreases on both sides. This is significant because the data tends to have fewer instances of unusually high values (outliers or special causes for variation (SCV) than other distributions. The curve flattens because there are few extreme numbers at either the lower or higher ends of the scale. This is what gives normal distribution curve its bell-like appearance.
Normal distributions in terms standard deviations and means
Let’s take a look at the normal distribution curve from a different angle. A curve graph is dependent on two factors: the mean and the standard deviation. Let’s review briefly the definition of standard deviation. The standard deviation measures how closely grouped or widely spaced data appear. It is one measure of dispersion. A standard normal distribution has an average of zero and a standard error of one. The center is identified by the mean, while the standard deviation determines height and width.
A large standard deviation, for example, creates a flat and wide-shaped bell. However, a small deviation can result in a smaller bell.
