Data Analytics vs Data Science: What’s the Difference?

Posted in: Big Data, big data analytics, Big Data careers, big data science, Careers, Data Analytics, data science - Sep 07, 2021

In today’s big data world, insights produce actionable results. But with big data comes the need for a greater understanding of the tools required to glean as much information as possible.

People who perform functions such as data analytics and data science help companies organize massive amounts of data and develop results-driven actions for the next steps. To help you optimize your data, let’s break down both categories, examining their differences and discovering how each provides value to business.

What Is Data Analytics?

Data analytics focuses on viewing the historical data. Analysts use datasets to learn information in specific areas, using specific software. For example, a data analyst may need to find out why a marketing campaign did well only in one region and nowhere else.

What Is Data Science?

Data scientists focus on machine learning and predictive modeling. They use scientific methods to learn insights from both structured and unstructured information. Data scientists estimate the unknown by seeking answers to questions, writing algorithms, and building statistical models.

Data scientists can arrange fuzzy sets of data using multiple tools simultaneously, and also develop their own automation systems and frameworks.

Why Do These Topics Get Confused?

Sometimes technical terms get confused because the technology is constantly evolving. While the tasks performed by data analysts and data scientists are related, and some people use the terms interchangeably, they are unique fields that differ in many ways. One of the biggest differences is their scope.

Data scientists focus on the big picture, finding meaningful correlations between large datasets. People who work in data analytics help to uncover the specifics of these extracted insights.

If you think of data science as more of an umbrella term that data analytics sits under, it may help keep the two separated in your mind.

How Are Data Analytics and Data Science Used in Business?

Data Analytics

Data analytics help companies know customers in more depth. Knowing who their audience is allows a business to evaluate things like ad campaigns and personalized copy. As a result, data analytics helps create content strategies and develop products — improving a company’s bottom line by boosting performance.

A data analyst manages structured data, often using SQL queries for such purposes. Most hold at least a bachelor’s degree in data analytics, or have backgrounds in statistics and database administration. If they lack formal education, data analysts can learn the tools they would use in a practical work environment. Some of the skills tools required are statistical analysis, database management and reporting, data analysis, R or SAS, and SQL.

If you’re interested in becoming a data analyst, you should look within these fields:

Finance
Health care
Travel
Gaming

Data Science

A data scientist helps in summarizing the performance of the company, and the overall health of the product. They’ll analyze the businesses’ health, find problems, and show enterprises how to deal with them. Companies can then predict the success rate of their strategies by using data science.

Data scientists can be data engineers or big data architects. In addition to mathematical and statistical knowledge, hacking skills, and substantive expertise, many data scientists hold a master’s degree in data science.

Some tools and skills that data scientists rely on are machine learning, software development, Java, Hadoop, Python, and data mining/data warehousing. In addition, data scientists responsible for handling unstructured data use NoSQL.

If you’re interested in becoming a data scientist, you may want to seek out:

Search engine engineering
Machine learning
AI
Corporate analytics

Data Analytics vs Data Science

While data analytics and data science are interconnected, they each play a vital, but different, role in business. When it comes to data analytics vs data science, understanding how to best utilize each of them will help your business analyze trends and develop the correct solutions.

What Is the Cost of Remote Work for Employees and Businesses?

Posted in: Blogs, Careers, Hiring, hiring challenges, HR Management, remote work - Sep 07, 2021

The COVID-19 pandemic forced millions of people to begin working remotely, but what is the cost of remote work? Employees have adjusted to a new “normal” work environment, and companies have adapted to a “new” operational domain. A Glassdoor study shows job seeker interest in remote work remains high, but businesses are less interested.

What can each side, businesses and employees, do to help alleviate tensions between parties? It depends on one’s point of view. Business leaders, for the most part, want to bring employees back to the office. Remote employees want the flexibility remote work provides, and are demanding a better work-life balance. Is there any middle ground?

Employees Crave Flexibility

Before the pandemic, many organizations provided a “work from home” option to their employees. Although not widely used, employees already working from home provided a blueprint to handle a crisis like COVID-19.

Surprisingly, even companies with relatively small infrastructure were able to allow thousands of employees to continue working. With everyone remotely connected, all employees began to realize the potential remote work could offer, including flexible schedules, no commutes, and more family time.

40% of employees said their organization hasn’t communicated its vision for post-pandemic work.

In April 2021, McKinsey released a report outlining employees’ questions and concerns during and after the pandemic. The survey shows that remote employees are more productive and less anxious when a company takes the time to communicate expectations.

Unfortunately, 40% of employees surveyed said their organization hasn’t communicated its vision for post-pandemic work. Communication alleviates frustration and burnout; employees deserve to know what’s coming. After the crisis ends, 52% survey respondents said they want a more flexible working model.

Businesses Remain Skeptical of Remote Work

Many employees believe remote work saves their employers money, but companies want to cut pay to those workers who wish to continue remote work.

For example, Google wants to lower wages if an employee moves to an area with a lower cost of living. Before the pandemic, many companies’ pay was based on the location of a central office. When companies like Google and other big tech firms floated this idea, many employees felt betrayed and outraged.

These employees don’t want to take a pay cut because they move to a different location. It’s worth noting that employees who moved before the pandemic didn’t receive a pay cut. And when business leaders relocated, their salaries didn’t receive adjustments.

That said, depending on the type of work, businesses leaders have trouble believing remote employees are actually more productive. They say things like on-site workers are more innovative thanks to in-person chats with colleagues. However, recent evidence shows office employees actually tend to work with headphones and ignore each other.

Business leaders also appeal to fairness. Many industries require people in specific business areas to be in the office, staffing call centers and manufacturing units. If these employees need to be there physically, the thinking goes, then so should the whole workforce.

As businesses threaten remote employees with pay cuts or layoffs, employees with new attitudes are leaving companies for full-time remote opportunities. As global demand for skilled workers — especially in technical fields — rises, employees believe they can demand more flexibility.

What’s more, some states are offering remote employees financial incentives to work there. Cities in states with a lower cost of living like Arkansas, Georgia, and Arizona offer stipends to people who want to work exclusively remote. Unfortunately, the incentive is just for the first year of work. It’s up to businesses to offer more long-term incentives to keep remote workers happy.

What the Future Holds

If the pandemic lasted a few months, these conversations wouldn’t be happening. As COVID-19 progressed, workers’ priorities shifted. Work will need to more flexible for both workers and businesses going forward. Recent outbreaks of the COVID-19 Delta variant are pushing out companies’ timelines to get employees back in the office.

The advantage, for now, is with remote employees looking for a more permanent remote work model. Business leaders trying to get these people back in the office face an uphill battle as long as the pandemic goes on. For the present, both sides need to think about the future, and how things can work differently.

Big Tech Brother IS Watching You

Posted in: analyzing customer data, Big Data, big data concerns, Blogs, bulk collection of data, consumer privacy, data and privacy, Internet surveillance, mass surveillance, Privacy policy - Sep 03, 2021

It has been known for some time that big tech gathers, analyzes, and sells vast amounts of consumer data. But a new survey by Surfshark highlights the extent of this user data surveillance.

Millions of User Data Requests Fulfilled

The study was based on an analysis of user data requests received by the likes of Apple, Google, Facebook, and Microsoft from the governments of 66 countries between 2013 and 2020. It summarizes the degree of fully or partially disclosed data requests provided by these companies.

They received a staggering 3,067,228 over that eight-year span. Out of that, almost two million requests were either fully or partially disclosed by the big tech companies. Surfshark research found that the minimum level of disclosure by any company was 55%, with one of them fulfilling more than three quarters of all government requests for data from around the world.

To make matters worse, the volume of requests fulfilled has steadily risen each year since 2012, and climbed sharply since 2017. This is yet another indicator that the surveillance state is not just a reality — the surveillance state is broadening towards becoming the surveillance planet.

EU Countries Among the Most Surveilled

When you view the number of requests per 100,000 people per year by authorities to big tech, Surfshark noted a threefold increase. In addition, the study found that seven out of the top 10 countries with the highest number of user data requests are from the European Union. Singapore, the United States, and Australia complete the list of the most surveilled countries.

“During the past years, the world has witnessed widespread adoption of physical and online surveillance tools,” said Vytautas Kaziukonis, CEO of Surfshark. “An increasing number of governments are deploying a range of surveillance technologies under the promise of maintaining order and public safety. However, it is evident that tracking and monitoring citizens can be far more overreaching and infringe people’s privacy.”

Seven out of the top 10 countries with the highest number of user data requests are from the EU.

A tiny island in the Mediterranean turned out to be the leader of the pack. Malta topped the list of user data surveillance, with 765 requests for user data per 100,000 people. Another tiny country in Asia, Singapore, ranked second at 373. Germany came in third place with 353 requests.

Which countries had the lowest rates? Kenya, the Philippines, and China were at the bottom of the list with less than one request per 100,000 people. However, the believability of official Chinese government data must be questioned. Even if accurate, it is likely that many additional requests are happening at a local level, without the need to send requests directly to the big tech giants.

US Government Surveillance Increases

With the European Union coming out so badly in the survey, those living in the U.S. should not feel too superior. Between 2013 and 2020, big tech received almost 40% more user data requests from U.S. government entities than from all the EU countries combined. In other words, the U.S. appears to be surveilling far more than any other nation.

Big tech received almost 40% more user data requests from U.S. government entities than from all the EU countries combined.

Google is by far the leader in the overall number of disclosed requests and has held that title since 2013. But compared to the others in big tech, it has a relatively low request disclosure average of 58%, in second place behind Apple. But in 2019, a new request fulfillment champion emerged — Facebook.

Its number of requests has grown nearly sixfold since 2013. It is also highest in partially or fully disclosing the bulk of those requests. And of course, the United States leads the way in Facebook requests per 100,000 people.

VPNs, Zero Trust Network Access, and the Evolution of Secure Remote Work

Posted in: Blogs, BYOD, network access, Network Access Control, remote access, remote teams, remote work, Secure Network Access, Security, VPN, Zero Trust Model, zero trust security, ZTNA - Sep 02, 2021

Do virtual private networks (VPNs) slow your work down? When it comes to remote access, there are some tough decisions to make. However, they all boil down to the following:

Simplify access as much as possible for your own users.
Maximize access restrictions for unauthorized parties.

Until now, many organizations have relied on the traditional perimeter-centric network security model and used VPNs.

VPNs Are Irrelevant

The main idea behind a VPN is to surround the network with a virtual perimeter, or in other words, a barrier to keep intruders out. However, in today’s decentralized environment, such a model is becoming increasingly difficult to manage.

Very few users need an equal level of access across the network. For example, third-party users (such as consultants) do not need access to the same applications or the same level of permissions as administrators.

Very few users need an equal level of access across the network.

VPNs are losing relevance as organizations move applications from the corporate network to the cloud, and the number of employees working remotely continues to grow. These changes affect the decision to use a VPN.

Let us look at several scenarios where traditional VPNs can fail. We’ll also touch upon a new security model that is easier to manage and provides more options for securing your network.

VPN Limitations

Many organizations have already realized that traditional VPNs and access controls designed to protect a closed perimeter are not enough in today’s environment, where remote employee access to internal company resources is prevalent.

Corporate networks are striving for decentralization. Remote and hybrid work models, as well as the need for third-party access, are spawning numerous help desk requests for remote network access.

In a perimeter-based, on-premises security architecture, passing all traffic through the data processing center can lead to increased response time and decreased productivity.

BYOD Goes Beyond Control

Allowing access from unmanaged and non-corporate devices means your network and assets are accessed from unprotected endpoints that pose a risk and may be infected by malware and/or controlled by a hacker.

It is not always possible to identify and monitor such endpoints, ensure the installation of all necessary security updates, and eliminate the risk of infection. Having hacked such a device, an attacker can try to penetrate the network.

Lack of Secure Access to Cloud Applications

VPNs lack the flexibility they need in today’s IT environments. They are difficult to deploy in the cloud and generally do not fully provide secure access to cloud-based IaaS applications and solutions such as AWS, GCP, and Azure.

Excessive Access Rights for Third Parties

For third-party users, the use of a VPN can be completely prohibited by rules that prevent the installation of VPN clients on the devices of people who are not employees of the company.

Where such rules are missing, third-party users can get high privileges and thus gain an unreasonably high level of trust. This simplifies access to company assets and confidential information for malicious actors.

Insufficient Network or Application Management Capabilities

The perimeter-based security model that a VPN offers is simple, but it takes away the flexibility. A VPN lacks granular access control options touching a number of key areas. This creates a lot of problems. Here are just a few of them:

Authorization and access control at the network level does not allow for granular control to be set up.
Potential risk of lateral movement and detection of confidential assets.
Lack of centralized application management.
Lack of built-in controls over user permissions.

Businesses Search for VPN Alternatives

Back in the day, when most users were in offices and almost all applications were hosted on local servers, VPNs were a great solution.

Hackers know that if they can bypass network defenses, they will face little resistance from internal systems.

However, data security is at serious risk today. Hackers know that if they can bypass network defenses, they will face little resistance from internal systems. Using VPNs and firewalls can create overconfidence in network security.

According to Gartner’s forecast, by 2023, up to 60% of enterprises will abandon VPN in favor of Zero Trust Network Access.

Adopt a Zero Trust Approach

VPN issues have raised awareness of the need for a security model that prevents trusted users from freely roaming the corporate network. The Zero Trust security model aims to meet this need.

Approved by influential organizations such as the US Department of Defense, the Zero Trust model implements the “Never Trust, Always Check” principle.

This model makes it possible to implement a scenario in which the required minimum of access rights to the application for the particular role are granted only to the appropriate persons. Ideally, this provides controls built into the applications themselves, as well as the ability to track user activity after logging in.

The Zero Trust model is more of a mindset, or a new paradigm, than a specific tool. There is no standalone solution to implement Zero Trust principles. Zero Trust encompasses the following:

Limited access at the level of individual applications
Authentication of each device and user

The Zero Trust model is difficult to deploy, but nevertheless, most organizations will switch to it sooner or later. The Zero Trust model can be implemented incrementally, group by group or application by application, but you should always consider the end-user experience.

Zero Trust Network Access

Choosing the right tools can greatly simplify and accelerate the transition to a Zero Trust architecture. Gartner has extended the concept of Zero Trust by defining an architecture called Zero Trust Network Access (ZTNA). The company defines ZTNA as “a product or service that creates an identity- and context-based, logical access boundary around an application or set of applications.”

Simply put, ZTNA replaces network-level permissions with application-specific permissions. It uses identity-based access control and contextual authentication. It considers user groups or roles, multi-factor authentication, IP addresses, locations, and time factors.

Simply put, ZTNA replaces network-level permissions with application-specific permissions.

Gartner’s definition continues: “The applications are hidden from discovery, and access is restricted via a trust broker to a set of named entities.” This can be implemented in a cloud-based ZTNA-as-a-service solution that makes the network invisible from the public internet segment.

Such a solution acts as a cloud demilitarized zone that “hides” the data center. The trust broker allows or denies access to specific applications on a case-by-case basis.

“The broker verifies the identity, context and policy adherence of the specified participants before allowing access and prohibits lateral movement elsewhere in the network,” Gartner says. By providing access only to the requested resource, the risk of a lateral movement attack is eliminated, because users only see the applications they are allowed to access.

All other applications are hidden for them. It can be implemented, for example, through a personalized portal that makes available only those applications that a particular user has access to. As Gartner notes, “This removes application assets from public visibility and significantly reduces the surface area for attack.”

Accelerate the Transition to Zero Trust

There are many reasons to accelerate the transition to the Zero Trust model. Companies are already struggling with VPNs as they grow and move to hybrid cloud environments, especially now that working from home has become commonplace.

Many of them are already contemplating a transition to a Zero Trust model for security and compliance reasons, seeking to enhance the protection of the organization’s assets.
