A cyber choice
We are slowly approaching the winter holidays and we are all thinking about the mountains or meeting our loved ones, although COVID has somehow limited our options. If we had to choose a method to get to a ski resort safely, what method of transport would we choose today: car, plane or train?
Statistically, the car remains the most risky solution in terms of transport itself, due to the increased possibility of an accident with other road users, fatigue at the wheel or weather conditions. From the point of view of the risk of COVID infection, it remains the safest method, if we exclude the home state. The flight to the desired destination is somewhere in the middle in terms of the probability of accident, but being a method little recommended during a pandemic and dependent on a well-located airport. The train seems a very safe method, accidents being rare, and the chances of passengers remaining alive and unharmed being appreciable, at least at the speeds allowed over the railway infrastructures in Romania. The space being more generous and airy,
If we look to the future, I hope a closer and non-pandemic one, when cars will become interconnected or even autonomous, and railway infrastructure and trains will be smart, would we choose the same? Let's include a new parameter in our choice: cyber risk.
Train's time list
The future of railway infrastructure is linked both to the new generations of telecommunications networks and to the creation of an IoT (Internet of Things) ecosystem, which will allow the dispersion of a multitude of sensors and actuators along the entire route and on trains. All these elements are necessary to increase the level of safety of passengers in the conditions of a higher speed on the rails. Latency, or in other words very low signal delay in 5G networks, allows real-time and accurate braking when a road obstacle is detected, detected with specialized radar equipment (eg LIDAR, Light Detection and Ranging, based on laser technology). Transmission of information collected from the field to the remote control center located at a distance and back to the train, then directed to the braking system, it must be done quickly, especially in the case of high-speed or very high-load trains. A train without a locomotive driver cannot operate without such a requirement. Or why not, we can also think of a train with a locomotive driver who is tired or who is suddenly facing an acute medical problem.
On the other hand, electronic switches remotely controlled by radio networks, railway traffic lights and other railway-specific mechanisms, once connected in an optimized command and control system, allow better traffic management on existing infrastructure. A traffic management solution certainly reduces human error and, implicitly, the risk of a collision of two train sets.

What to do to become a security analyst?
Professionals looking to work as security analysts need to have a technical and analytical profile at the same time, explains Foster. He says that the security area is one of the most delicate and, perhaps, the most difficult in technology. For this reason, before going to the security area, what is recommended is that the professional goes through other areas of technology, such as development, support, networks and cloud computing, for example.
For Foster, it is very important that those interested in the security career have a college and after the traditional course, seek national and international certificates. "Certified Ethical Hacker (CEH) and Certified Information Systems Security Professional (CISSP) certificates are very valuable to the market," he advises.
Learning the English language is also highly recommended by the executive. In the technology area, the Python programming language is a strong trend that can make life easier for the security analyst, even if he is a professional with little contact with programming. "It is very important that the professional knows how to develop to automate some routines and processes in case he does not find an application on the market†he explains.
Rafael Foster, says that when he decided to go to the security career, he didn't have many specific courses in the area, so he studied Computer Networks at the Catholic University of Santos, but as soon as he graduated, he sought a specialization in security management from information.

What are the Cyber ​​attacks?
The cyber attacks are actions performed by criminals, who use as network vulnerabilities to attack and steal data. Data that is allowed, and what are the main ones stolen, that cause great damage to your company.
Research shows that Brazil is the second country that suffers the most cyber attacks, registering 120.7 million attacks , until the year 2018, according to research by the Dfndr laboratory .
Following growth, in 2019 was not much different research showed about a 14% to increase the diversity of malware .
Unfortunately, the year 2020 did not bring improvements. On the contrary, among many things, the year was marked by an exploitation of cyber attacks. A 400% increase in the number of attacks recorded, according to Next Generation data .
As we know that the best way to prevent and keep a company safe is to know it as threats, presenting some of these attacks.
Virus
A virus is a program or code used to damage your computer, corrupt system files and destroy data. The virus remains inactive on the machine until it is executed, that is, for the infected or necessary virus to run the infected program.
From there, it can infect other computers on the network , steal passwords and data, corrupt files, forward spam to e-mail contacts, or even control the computer.
Worms
They are older than viruses, they remain in fashion until the end of the 90s and almost a decade, arriving as attachments to messages. One person opened an email and the entire company was infected in a short time.
What makes it so devastating is its ability to spread without end user action . Viruses, on the contrary, prompt the end user less or initiate.
Anetwork engineeris a technology professional who has the necessary skills to plan, implement and oversee the computer networks that support in-house voice, data, video and wireless network services.
Adware
In this attack, one strategy is to try to export the end user for unwanted and potentially intentional advertising. A common adware program can redirect searches from a user's browser to web pages that look like other product promotions.
This type of attack aims to obtain useful information for users such as: the location, details of access passwords (passwords) and IP addresses of the computer or electronic mail.

How to become a cybersecurity professional?
Once again, news began to appear with analytics as if in the next couple of years there would be a catastrophic shortage of information security specialists on the market (we will abbreviate it to the abbreviation "IS"). According to XX, Russia is already short of about 30 thousand specialists. Sounds promising from a career standpoint - low competition, go and work. However, what does the IBshnik's career look like on the Russian market?
My work experience in this market is approaching a round date, except for specialized education in this area, and during this time a stable opinion has been formed about the information security market in Russia and a career in this area. This is what will be discussed further. Everything described below is more likely for those who decide to break into (in fact, it is enough just to step) into this market or look at something else.
Information security specialization is often described on various resources as something complex, mysterious, unidentified and romantic. Basically, everyone who is not yet familiar with this area associates work in information security directly with hackers and it seems that all information security specialists have these skills (they hack websites, steal passwords, break through IP, etc.). Because of this, entering this market looks as difficult as possible and it often seems impossible for a candidate to get a job as an information security officer without having this knowledge. However, the realities are such that most information security specialists do not even know how this happens. Moreover, a significant part of the "specialists" are not particularly well versed in IT. Why is this so?
The information security market is divided in the same way as all other markets into customers and performers. Let's start with a description of the work on the customer's side.

Specialized systems for computer network simulation
There are special software systems focused on modeling computer networks in which the process of creating a model is simplified. Such software systems themselves generate a network model based on initial data on the topology and protocols used, the intensity of request flows between computers on the network, the length of communication lines, the types of equipment and applications used. Simulation software systems can be highly specialized and versatile enough to simulate networks of different types. The quality of the simulation results largely depends on the accuracy of the initial network data transmitted to the simulation system.
Network modeling software is a tool that can be useful to any corporate network administrator, especially when designing a new network or making drastic changes to an existing one. Products in this category allow you to check the consequences of implementing certain solutions even before you pay for the purchased equipment. Of course, most of these software packages are quite expensive, but the potential savings can also be quite substantial.
Network simulation programs use in their work information about the spatial location of the network, the number of nodes, the configuration of the connections, the data transfer rates, the protocols used and the type of equipment, as well as the applications running on the network.
The
systems engineerwill often work together with a project manager and the engineering crew and becomes the primary point of communication to interlink between the two to simplify the accomplishment of a successful system.
Usually, a simulation model is not built from scratch. There are ready-made simulation models of the main elements of networks: the most common types of routers, communication channels, access methods, protocols, etc. These models of individual network elements are created based on various data: the results of tests of real devices, analysis of their operating principles, analytical relationships. As a result, a library of typical network elements is created, which can be configured using the parameters previously provided in the models.
Simulation systems usually include a set of tools for preparing the initial data about the studied network - preprocessing the data about the network topology and the measured traffic. These tools can be useful if the simulated network is a variant of an existing network and it is possible to measure the traffic and other parameters needed for the simulation. In addition, the system is equipped with tools for statistical processing of the simulation results obtained.

High demand for cybersecurity professionals
It is difficult to imagine a world without internet. Whether professionally or personally, technology is present in the daily lives of most people. And with the popularization of web browsing, the information security sector is gaining more and more prominence in the virtual environment in the area of ​​technology. Also known as cybersecurity or cybersecurity, the segment seeks to protect data from users and companies from bad practices or misuse. This issue is so relevant for companies, that there is a high demand for professionals in the field.
The truth is that
virtual assistant are an essential part of the modern workforce and working as a virtual assistant has the potential for a great deal of personal career growth and success.
A report by the International Information System Security Certification Consortium (ISC) ² found that there is a shortfall of 4 million professionals in the sector worldwide. In Latin America alone, the demand is for 600 thousand specialists. Brazil has the second largest cybersecurity workforce, second only to the United States, but still has difficulty in training professionals. Better understand this sector and what is expected of professionals.
The high demand for information security
PhD in applied computational physics and professor in the computing department at the Federal University of São Carlos (UFSCar), Paulo Matias notes that the high demand for information security professionals is due to the popularization and democratization of the internet. "This expansion is very good, but it requires the technology sector to be more concerned with the security of these devices. Another factor is that we are using the internet for more purposes and for longer periods. This causes a much greater amount of information to be stored and demand protection â€, he indicates.
And the professor points out that it is not only individuals who are increasingly dependent on technology, but also organizations. "As a result, not only have some companies sought out cybersecurity professionals to generate a competitive advantage, but the government has also been pressured to regulate the sector. However, the demand is still much higher than the market's capacity to serve it. This demand only tends to increase with greater awareness of organizations and with the introduction of the General Data Protection Law and new regulations â€, he analyzes.

Software architecture or software engineering: what are the differences?
A software architect person does not have the same functions as a software engineer person. Understanding these differences is essential to defining your next career steps. A person from the first area develops the solution architecture. It fulfills the following functions:
organizes the blueprint for the solution design, identifying which elements are necessary for the elaboration of the solution and showing how they act together;
distinguishes between elements that can be functional and those that are not functional in the domain;
visualizes the automation behavior of the solution as a whole.
It is possible to make an analogy with the positions of architecture or engineering in civil construction: the architect person is the one who designs the steps for the creation of a building, putting in the plan how it should be delivered at the end of the construction process, taking into account issues such as aesthetics, design, functionality, etc.
The engineer is responsible for the execution of the project , articulating the other collaborators to be able to put into practice the definitions of the architect person during the construction. In other words, one is more linked to the design of the project and the other to execution.
The same comparison can be made in the software creation environment. The architecture area is responsible for the entire conception of the solution project, identifying how the articulations between the different parts will take place, defining their design, among other important points of this stage.
The engineering area will be responsible for articulating the development, operation and tests . It is clear that he must have knowledge of software architecture for this, but, his functions, as a rule, are more linked to the executable aspects.

Why do I have to fill out another questionnaire?
Your assessment covers a specific scope, which depends on your organization's corporate name, indicated in the questionnaire. This means, for example, that different production sites or business divisions cannot be included in a single assessment.
If only one of your production sites or business divisions has been assessed and your business partner is interested in the CSR performance of another, it may be necessary to complete an assessment separately for this scope.
If you want to change the scope of the evaluation, we ask that you contact us before starting to fill out a new questionnaire.

Avoid overheating on computer
One of the main villains in the appearance of the blue screen is the overheating of components, especially the processor.
When your computer reaches a very high temperature, performance will be compromised. It is possible that it will turn off automatically without displaying the blue screen. This procedure consists of maintaining the integrity of internal circuits. However, it is possible for the blue screen to appear and your computer to restart.
As one of the fastest-growing professions out there, They have a huge range of fields in engineering to choose from and knowing which ones pay the most is definitely going to interest them.
See more about theengineering salary.
An excellent tool for checking the temperature of your computer's components is the HWMonitor . If the temperature is too high, you need to open your desktop and perform a thorough cleaning of all hardware components, especially the cooler.
If none of the procedures described above work, you may need to perform a complete formatting of your system. If you were unable to find any damaged files or irregular components, it will be difficult to find the cause of the blue screen display. Back up your files and format your computer. Remember that if this does not resolve the blue screen, the problem is with the hardware and you may have to replace some components. An inspection carried out by an IT professional will be of great use.

Network management, especially external ones
Network management, especially external ones, is one of the biggest difficulties encountered by companies.Other problems are related to:
Bandwidth
Companies encounter several obstacles when they need to increase their bandwidth.One is that the service is often expensive.The other is that it is neverattendedto immediately.
Branch complexity
When there are several devices with the same function in the branch and management in silos, it is necessary to use several services to deploy them, monitor them and solve problems.
Rigid architecture
By redirecting traffic from a remote branch network, your cloud applications end up being impacted.Whenever it is necessary to use new applications, reconfiguration of the network will be necessary, causing a greater demand on IT.
A network engineer is a technology professional who has the necessary skills to plan, implement and oversee the computer networks that support in-house voice, data, video and wireless network services.

Scan for viruses and malware.
While some software vendors fix major problems in their products by releasing completely new versions, others can fix minor bugs through patches, small software updates that fix problems found by developers or users. Even if you are sure that you have installed the most up-to-date version of the software, it would be advisable to visit the manufacturer's or developer's website for new updates, as the vendor may have decided to quickly fix a newly discovered problem by patching it up. instead of a remake.
IT specialists should keep track of all the IT-related issues in the organization. Informational technology specialists should also have good communication skills, as they have to interact with clients and their team members to coordinate on issues.
Scan for viruses and malware.
Viruses, spyware, and other forms of malicious software (commonly known as malware) can not only compromise the privacy of your nonprofit organization, but also cause other applications on your computer, especially web browsers and email clients, to become crash, fall or stop working completely. If these eight tips haven't helped you solve your software problem, you may need to scan your computer using both antivirus and antimalware applications, programs designed to find and destroy viruses and malware.
When running one of these programs, it is a good idea to use the most comprehensive search mode available. Also remember to shut down and restart your computer if the antivirus or antimalware program finds and removes threats from the computer. For more information on how to get rid of viruses and malware, including tips on anti-virus and anti-malware applications, read the TechSoup articleRemovingViruses, Spyware, and Other Forms of Malware . It should be noted that currently most viruses and malware attack computers with Windows operating systems, although Mac OS malware threats have occasionally been detected.
Check for possible conflicts with the firewall.
Many nonprofits do not have the budget for the purchase of a centralized software- or hardware-based firewall and instead choose to install personal firewall software like ZoneAlarm Free on every computer in their office. Although personal firewalls can be an important defense against hackers and other security threats, they can also confuse users, as they frequently display messages asking the user if they want to run or block a program. You may experience software problems because you accidentally instructed your personal firewall to block the program in question when responding to one of these messages. Check your firewall settings to see if problem software has been inadvertently added to the list of blocked programs. If so,
Boot into safe mode.
As mentioned above, some software malfunctions can be caused by operating system settings or other system problems. Windows and Mac operating systems have a troubleshooting environment known as Safe Mode, which disables applications and processes that are not essential to the system, theoretically making it easier to isolate problems.
Most computers allow you to enter Safe Mode by pressing the F8 key when the computer is starting up. If you are using a Mac, you can enter Safe Mode by pressing the Shift key while or after the computer boots. Once in Safe Mode, open the problem app and try to recreate the problem that arose while in normal mode.
