What is Cybersecurity?



/What is Cybersecurity?

The rapid pace of technological progress has brought unprecedented opportunities for innovation, communication and efficiency. However, as dependence on technology increases, so does the risk of cyber attacks. Cyber security has become one of the most pressing issues of our time, affecting individuals, companies and governments around the world. The consequences of cyber attacks can range from financial losses to disruption of critical infrastructure and even loss of human life.

In recent years, we have witnessed a number of high-profile cyber attacks, including the WannaCry ransomware attack that affected hundreds of thousands of computers worldwide, the Equifax data breach that exposed the confidential information of millions of people, and the SolarWinds supply chain attack that involved many government agencies and private companies. These incidents underscore the seriousness of the cyber threat situation and the need for effective cybersecurity measures.

The current state of cybersecurity

Despite significant efforts to improve network security, the current state of cybersecurity remains precarious. Cyber attacks are becoming more sophisticated, more frequent and have a growing impact. Cybercriminals are constantly developing new attack methods and exploiting vulnerabilities in software and hardware systems.

Moreover, the COVID-19 pandemic has created new opportunities for cyber attacks. With the rapid shift to remote work and online services, organizations are more vulnerable than ever to cyber attacks. Phishing attacks, ransomware attacks and other forms of cyber attacks have increased during the pandemic.

The most common cyber threats

There are many cyber risks that individuals, companies and governments should be aware of. Here are the most common risks involved:

  • Malware – is a type of malware that is designed to damage computer systems or steal sensitive information. Typical types of malware are viruses or Trojans.
  • Ransomware – is a type of malware that is designed to extort money by blocking access to files or a computer system until a ransom is paid.
  • Phishing – is a type of social engineering attack in which cybercriminals use emails, phone calls or text messages to trick people into divulging sensitive information or clicking on a malicious link.
  • DDoS attacks (Distributed Denial of Service) – involve flooding a site or server with traffic, causing it to crash and make it unavailable to users.
  • „man-in-the-middle” attacks – these occur when an attacker intercepts and alters communications between two parties in order to steal sensitive information or inject malicious code.
  • Zero-day exploits – are vulnerabilities in software or hardware that are unknown to the manufacturer and therefore not patched. Cybercriminals can exploit these vulnerabilities to gain unauthorized access to systems or data.

Cybersecurity challenges

There are several challenges we face in achieving effective cyber security. One of the primary challenges is the shortage of qualified cyber security professionals. This industry is experiencing a significant shortage of qualified professionals, making it difficult for organizations to find and hire qualified experts to protect their systems.

Another challenge is the complexity of modern technology systems. With the proliferation of IoT ("Internet of Things") devices, cloud computing and other emerging technologies, the attack surface has increased significantly, and this makes it more difficult to detect and respond to cyber attacks.

Emerging technologies and strategies

Despite these challenges, there are new technologies and strategies that offer hope for a more secure future. For example, artificial intelligence (AI) and machine learning (ML) can be used to detect and respond to cyber threats in real time. Blockchain technology has the potential to increase data security and privacy, while quantum computing may enable us to develop more secure encryption methods.

In addition, organizations are taking a more proactive approach to cyber security. This includes implementing security measures such as multi-factor authentication, training and awareness programs for employees, and continuous monitoring and testing of systems.

Summary

In conclusion, cyber security is a critical issue that affects all aspects of our lives. Cyber attacks have the potential to cause significant damage. However, there are new technologies and strategies that offer hope for a safer future. By working together, we can overcome cybersecurity challenges and build a safer, more protected digital world.

Servers and Data Centers



/Servers and Data Centers

Data centers and servers are the backbone of today's digital world. They store, process and transmit huge amounts of data every day, enabling us to access information, communicate with others and conduct business online. In this article, we will outline the importance of data centers and servers, how they operate, and the challenges and trends shaping their future.

What is a data center?

A data center is a facility used to store computer systems and related components, such as telecommunications and storage systems. Data centers are designed to provide high levels of availability, security and reliability to ensure that stored and processed data is always available and protected.

They come in a variety of sizes, from small server rooms to large corporate facilities that can cover hundreds of square meters. Some data centers are owned and operated by individual organizations, while others are operated by third-party service providers and offer hosting services to multiple customers.

How do the servers work?

Servers are the backbone of data centers, providing the computing power needed to process and store data. A server is a computer system that is designed to provide specific services or resources to other computers or devices connected to a network.

Servers can perform many functions, such as hosting websites, running applications and storing and processing data. A server can be a physical machine or a virtual machine that runs on top of a physical machine. Virtualization technology allows multiple virtual servers to run on a single physical machine, allowing organizations to maximize computing resources and reduce costs.

Challenges and trends

As the demand for digital services continues to grow, data centers and servers face several challenges and trends that will shape their future.

  • One of the primary challenges is the need for greater energy efficiency. Data centers consume huge amounts of energy, and as the number of data centers grows, so does their environmental impact. To meet this challenge, data centers are adopting more energy-efficient technologies, such as advanced cooling systems, and using renewable energy sources such as solar and wind power.
  • Another challenge is the need for greater security. Data breaches can have serious consequences, both for organizations and individuals. Data centers are implementing more stringent security measures, such as multi-factor authentication and encryption, to protect against cyber attacks.
  • In terms of trends, "edge processing" is becoming an important trend in data center and server architecture. It involves processing data closer to the source, reducing latency and improving performance. This is especially important for applications requiring real-time data processing, such as autonomous vehicles and industrial automation.

Summary

Data centers and servers are essential components of the digital infrastructure that supports our modern world. They enable us to access and store vast amounts of information, and provide the computing power needed for critical applications and services. As the demand for digital services continues to grow, data centers and servers will face ongoing challenges and trends that will shape their future. By adopting innovative technologies and strategies, data centers and servers can continue to evolve and meet the needs of our rapidly changing digital world.


Data Protection in Company



/Data Protection in Company

Over the past few years, data security has become a priority topic among business owners. Through the development of technology, more and more sectors are being digitized, not only improving the operation of the company, but also exposing it to attacks from cyber criminals. We can’t provide 100% protection for confidential information, but by putting the right steps in place, we can minimize the risk of a potential leak. As a result, both the company’s good name and budget will not suffer. 

In an era that condones employees to use private devices for business purposes, security issues have never been so sensitive. Surveys show that only 40% of working people in Poland consider issues related to protecting the equipment they work on. This poses quite a challenge for owners of businesses, who must ensure not only the security of the data itself, but also systematize regulations in relation to the surveillance of their subordinates’ private devices. We need to realize the consequences that can accompany a data leak – even if we run a small or medium-sized company. Leakage of customers’ private information, caused either by the deliberate actions of external hackers or by an employee who took advantage of an unlucky open Wi-Fi network, can cost our company exorbitant sums of money (leaving aside the risk of possible liability under, for example, data protection regulations). 

The potential threat may not only come from the network – it also applies to theft or damage to physical equipment. That’s why we should make an effort to ensure that vital equipment for the operation of the company is properly secured, especially against the possibility of outside contact. In terms of data protection, establishing adequate oversight is much more crucial. The basis is choosing the right security system – one that is tailored to our company. It is at this stage that it is crucial to establish a data hierarchy, so that access to the most important information for the company, such as confidential customer data, will be reserved for those with authorizations – that is, employees for whom such knowledge is absolutely necessary to perform their duties. Let’s also ask ourselves an important question – what will we do if somehow this data is lost? If we do not yet know the answer, let’s think as soon as possible about separate a team whose task will be to periodically create backups and properly secure them. This way, in case of an attack and deletion of information or ordinary failure, we will be able to recover the data. The most perfect system will not work if it is not used by competent people. That’s why it’s so important to sensitize the employees themselves to device security issues. Let’s start by making a list of of tasks that all subordinates will have to perform before integrating their device into company operations, and another one describing cyclical procedures (such as updating or frequently changing passwords). Employees’ knowledge will be based on this, while separate training and each time introducing new people to the company’s security routine may be necessary to fully implement the security requirements. 

Like any professional solution, a surveillance system for confidential information first requires prudent planning. We do not have to deal with this ourselves – there are companies that professionally deal with assisting companies in implementing security measures. However, we should remember to use common sense in this matter as well: when deciding on the services of specialists, be sure that they really are the best at what they do. In the age of the Internet, we can get opinions on almost any service provider, a good old recommendation by a friendly company will also work. Thanks to all these measures, we will be able to sleep peacefully, and our company – to function without unpleasant surprises.
