If 35% of IT leaders expect to reduce their technology and innovation budget by 2021, the expectation is to focus efforts on managing expenses and controlling costs. Thus, these executives hope to increase the operational efficiency of the businesses.

Not least because, part of the IT budget in 2020 was intended to increase the infrastructure of companies to support the remote work of employees. This is the case with NorthMarq, a mortgage services company.

In three weeks, the company expanded its IT infrastructure, developed a new VPN, purchased notebooks for remote employees and planned a capital investment in this area for the next 18 months. All this due to the sense of urgency brought about by the crisis.

Extra Space Storage, a storage unit company, had a traditional contract signing process. However, the new coronavirus pandemic temporarily closed offices.

A data center technician should answer questions and take queries from various sources and provide them with the right information.

With no forecast for the resumption of business, IT executives entered the scene. In three days, they were able to develop, test and release a remote subscription feature for granting a storage unit to the customer.

Operational efficiency has always been a will for Extra Space Storage, but the company has always hesitated to change the processes that, for it, worked well. The expectation is, now, to take advantage of the DevOps team to make more agile deliveries.

The time when all cloud resources were centralized in the data center is beginning to fade. Today it is already possible to find cloud applications that help to enhance the performance of ships, aircraft, cars and homes. Access to cloud computing and storage is moving from robust data centers to rural communities, remote areas and even orbits close to Earth. In practice, the cloud is arriving everywhere.

The DHCP server allots a dynamic IP number. The DHCP server has a group of IP addresses which can serve the purpose.

Today, advances make it possible to bring cloud technologies closer than ever to customers around the world. As we see the expansion of 5G networks, operators begin to implement wavelength zones so that traffic from 5G device applications can take full advantage of the low latency and high bandwidth of these modern networks. When fast connections to the cloud are expanded to the furthest points of the network, many good things can happen.

By removing latency and performing more processing on the device located at the edge of the network (or edge), we are beginning to overcome the only limitation that still affects all technologies on Earth: the speed of light. Operations that require very low latency, including autonomous cars, natural language processing and the active management of vital infrastructures, no longer have to rely on moving information from the ends of the planet to a central server. It is now possible to perform tasks where the results are most needed. And do you know what the effect is? Autonomous cars become reality; factories, homes and offices are becoming increasingly efficient and resilient; and those who like to play video games can count on a faithful representation of the work, wherever they are.

As the cloud expands from centralized locations to the environments in which we live and work, we will increasingly see software running on the cloud running close to you, which will lead to improvements in all aspects of life, including health, transportation, entertainment, manufacturing and more. In 2021, this transition to the edge of the system will be accelerated.

Finally, one of the primary elements in the infrastructure for network design is its security.

We know that the Internet is a world of many possibilities and, while this is positive, facilitating access to information and optimizing business time, on the other hand, there are still many points that can be negative.

After all, it proves to be a somewhat insecure environment, with risks and intrusions to the network, to steal sensitive data and information. A company that values ​​its future and its market competitiveness can never let that happen.

For this reason, it is necessary to prepare the infrastructure to receive the best resources that strengthen the security of the network: firewalls. The firewall is a tool that aims to limit access to a computer's input and output ports through the network, preventing intruders from entering.

banner-partnership-12

In other words, this feature is able to prevent the entry and exit of information from the computer, preventing confidential files from being sent to the network.

In a practical way, the firewall blocks the sending of data packets that have not been configured in your whitelist.

There are three types of firewalls: those that are located on the network, on computers and in applications. They all help to ensure that no malicious activity takes place on the network, on computers, let alone on the website, email servers and other applications that the business uses.

The tasks for a server technician are varied, with everything from providing cost estimates to upgrading hardware and software as needed. The server for a business hosts a lot of data and information, and server repair technicians need to be aware of what a business needs.

Therefore, for the network design to be complete, it is necessary to pay attention to this detail: the infrastructure must be compatible with the types of firewalls chosen by the business.

In addition, it is necessary to rely on other solutions that help combat any unauthorized activity on the network and that can harm the business, such as antivirus and antispyware and malware solutions to help maintain the security of the network. Together, they will help to reduce any possibility of invasion.

how to avoid the main threats to which your company may be exposed?
Spoofing and Phishing
Spoofing is a type of technological forgery that seeks to deceive the user, making him believe that the source of information is reliable, settling on his network. Phishing, in turn, occurs when criminals trick the user into revealing personal information, such as passwords, credit card details, social security numbers and bank account numbers. Just like spoofing, they do this by sending fake emails or directing you to untrusted websites.

These two threats have become quite common and, increasingly, cybercriminals have improved their technique to deceive users. How to protect yourself? In addition to investing in antivirus and firewall software so that these threats do not reach your network, the ideal is also to take some precautions, such as:

Do not respond to any email requesting account information or personal data, even if the sender is from a known user or institution.
If you suspect something, do not open the email or link.
Watch out for any changes in the appearance or behavior of trusted sites. Before passing the information requested on the page, be 100% sure that it is true.
Be wary of a tone of urgency and alarm, they are usually dangerous.
Do not open attachments or install anything that comes from unknown emails or that you are unsure of.
Ransomware (Data Hijacking)
Ransomware is a type of attack that makes stored data inaccessible and, usually using encryption, requires ransom payment to restore access to the user. This type of attack happens mainly with companies, and the demand for payment via cryptocurrency, especially bitcoin, has grown.

The most common ways for ransomware to spread are by e-mails with the malicious code attached or that induce the user to follow a link and intrusion due to system vulnerabilities. It is very important to avoid being infected, because once your data is hijacked, it is very difficult to recover it. So stay tuned:

A network engineer is required to have the necessary skills to plan, implement and oversee the computer networks that support in-house voice, data, videos and wireless network services.

Keep the operating system and programs installed with all updates applied;
Have an antivirus, firewall and other security software active;
Be careful when clicking links or opening files;
Make backups to have access to your data, in case your equipment is infected.

The software-defined wide area network is designed not only for the current but also the future needs of the organization. In addition, it can help reduce your overall bandwidth costs.


Analysts estimate that about 30% of companies are already using public cloud services; the volume of their use will increase annually by 17%.

In addition, the proliferation of mobile versions of enterprise applications is increasing; they become available on various devices outside the office. This is a very important trend, given the fact that in 2018 half of all employees in the corporate sector will use mobile devices. Networks have become a strategically important asset for companies, and therefore IT leaders must plan for alternative methods of connecting mobile devices in corporate wide area networks.

The communication requirements of companies have outgrown the capabilities of private WAN MPLS services to provide communications between remote offices and data centers. The current network architecture, which is more than ten years old, does not meet today requirements: an increase in the number of connected devices, mobility, increased security needs. The software-defined wide area network (SD-WAN) is designed not only for the current needs of the organization, but also for the future. SD-WAN technology allows you to create hybrid networks that combine access technologies such as Internet services, dynamic traffic routing and real-time connection configuration based on available bandwidth or selected criteria. Besides,


In 2015, the emerging SD-WAN market was estimated at almost $ 225 million.According to IDC forecasts, in 2016 this market will grow by 165% to $ 595 million. Then in 2017 - by 129%, in 2018 - by another 87%, reaching 2.6 billion. According to analysts, by 2020 the average annual growth rate of the SD-WAN market will be 93%, which will allow it to reach more than $ 6 billion.

1. Assist in telephone service and registration of work orders
The first of the IT support activities is to assist in answering service request calls.

In large companies, it is necessary to have a person responsible for receiving calls, registering the reasons for the service request and creating the service order register.

Service orders are usually recorded on a system and distributed among professionals on the IT support team.

Thus, the work of each technician is more organized and they can go out to solve one or more calls and even be assigned to new ones during the workday.

2. Price quotation for computer parts
Another of the IT support activities is to quote the prices of the parts needed for equipment maintenance services.

With this work, the IT support team keeps contact with several suppliers from different segments and thus creates a close relationship.

Thus, it is possible to obtain parts at a good cost-benefit and, especially, when it is necessary for service.

As much as maintenance activities minimize emergencies, there is always a situation where it is necessary to obtain last minute parts.

If the company has a list of suppliers for reference, it is easier to find a solution.

3. Taking questions from customers
IT support activities also involves asking questions about technical issues or any error in the daily use of equipment and programs.

These calls can take place over the phone, without the need to move a technician to the location.

Every company needs to have an IT support reference to turn to when there is a question in the team.

In such cases, the technician can identify patterns of inappropriate use of the systems that can be corrected so as not to jeopardize the security of the stored data.

4. Conduct training
Other IT support activities include training for companies.

The lack of knowledge in relation to technology, many times, makes the companies need to align the understanding about the use of the equipment.

Technicians are well-versed with the brass tacks of the services / products, which they provide support for. If IT Technicians are unable to solve a problem, it is escalated to the senior team.

The good practices developed to guarantee the security of the company's systems, the longevity of the equipment and avoid errors in the insertion of data that can harm the results, etc.

The training can be provided by IT support technicians so face and also virtual customers.

Cybersecurity is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. It is also known as information technology security or electronic information security. The term is applied in different contexts, from business to mobile computing, and can be divided into a few common categories.

  • The network security is the practice of protecting computer networks from intruders, either attackers or malware targeted opportunistic.
  • The application security focuses on maintaining the free software and devices threats. An affected application could provide access to the data it is intended to protect. Effective security begins at the design stage, long before a program or device is implemented.
  • Information security protects the integrity and privacy of data, both in storage and in transit.
  • The operational safety includes the processes and decisions to manage and protect data resources. The permissions that users have to access a network and the procedures that determine how and where data can be stored or shared are included in this category.
  • The disaster recovery and business continuity defines how an organization responds to a cybersecurity incident or other event causing operations to stop or data loss. Disaster recovery policies dictate how the organization restores its operations and information to return to the same operational capacity as before the event. Business continuity is the plan the organization resorts to when trying to operate without certain resources.
  • The training of the end user addresses the most unpredictable factor cybersecurity: people. If good security practices are violated, anyone can accidentally introduce a virus into an otherwise safe system. Teaching users to remove suspicious email attachments, not to connect unidentified USB drives, and other important lessons are critical to the security of any organization.
  • The goal of subnetting is to create a fast, efficient, and resilient computer network. As networks become larger and more complex, the traffic traveling through them needs more efficient routes.

Most of the survey participants (71%) by the time they leave school already know that there is such an industry - information security. As a cybersecurity company for 18 years, this cannot but rejoice. Someone got the first knowledge about the topic of security from films and books, someone got acquainted with the basics in computer science lessons and in programming circles, and someone came across the topic of information security after learning about the hacking of their page on social networks. After an independent study of the issue, many realize the specificity of the tasks of an information security specialist (74% of respondents), as well as the prospects and stability of this area of ​​the IT industry (15% of respondents). At the same time, 11% consider a decent level of wages in the industry to be especially attractive.

Indeed, the tasks of a cybersecurity specialist are very non-trivial, and few have a full understanding of what exactly, from the point of view of professional niches, attracts young people in this area. For example, only 14% noted reverse engineering as the most interesting area, 12% highlighted red teaming and 13% - infrastructure information security. But it is even difficult to call it the tip of the iceberg, because there is such a wide range of tasks and opportunities in the field of information security.

Specializations in information security: variety of terms
There are many areas of cybersecurity today. But, by and large, the area of ​​information security in an enlarged manner has two components - technological and regulatory. I want to note right away that the position can sound differently, regardless of the chosen direction of professional development: specialist, analyst, consultant, manager, engineer, etc. The name is not as important here as the tasks performed.

Know more: What is SOW ?

Let's start with the regulatory component, which is often called compliance. It includes several vectors: methodology, standardization and awareness 1. So, here it is supposed to solve very specific problems: work with standards in the field of information security (ISO 2, federal laws, orders of FSTEC, etc.), analysis of the real situation in the company, bringing existing documentation and infrastructure to conformity with the provisions of various international and domestic standards, interaction with colleagues from related IT departments. Often, all of the above is complemented by awareness-tasks for the development of methodological manuals in order to increase the literacy of company employees in information security issues and their direct training.

The technological aspect of information security unites two camps - the red team and the blue team. The blue team is sometimes referred to as defensive security. These include: security operations center (SOC), threat intelligence (TI), forensics, cyber intelligence.

Ideally, if we have a computer that is still running Windows XP on our network, we get rid of it. Sooner. Not only because of the security issues involved in connecting it, but also because facing the Internet will not help us much.

If we have a Windows 7 computer, all we have to do is upgrade to Windows 10 for free, with the trick that Microsoft gives us. Windows 10 works just like Windows 7 in terms of performance and needs the same minimum requirements. However, the improvement in security we get is incalculable.

If, in the end, there is nothing left but to continue using the same unsafe operating system, then there are some tips that will help us stay safe.

A data center technician should answer questions and take queries from various sources and provide them with the right information. Knowledge of technology requirements is one of the required skills for a data center technician.
