In this sense, connectivity plays a central role in digital innovation, permeating our personal, social and professional lives. Since the evolution of the internet, from dial-up to the arrival of 5G, connectivity has been a driving force in technological change.


Web 2.0, smart mobile devices and high-speed internet marked the initial waves. Now, Web 3.0, with the Internet of Things (IoT), big data, artificial intelligence, chatbots, metaverse and much more, are reshaping our reality.


In this article you will understand the importance of connectivity in digital innovation and how technological changes are transforming our lives and businesses.


Digital innovation is a necessary journey for companies of all sizes and sectors, as those that do not keep up with technological developments inevitably fall behind.


External and internal network: what is the difference?


When we talk about connectivity and technology, we are talking about devices that communicate through networks.


Thus, there are external and internal networks that need to be installed for this connection to happen and be as effective as possible.


In a company, in a home, and in any place that uses systems and devices connected to the internet.


In general, the external network is the one that allows the internet to be made available to each customer of a provider. An internet provider, for example, can have millions of customers and each of them represents an external connection that needs to be made.


So, from the moment the network enters some location, we have internal networks. They are necessary for the internet to be available on the various devices we use on a daily basis: cell phones, tablets, computers, televisions, video games, among others.


Internal Networks: Fundamentals and Components


Internal networks enable devices to connect to the internet. And for that, there are different options to choose from.


Switches


Switches play a vital role in commercial networks, acting as controllers that connect devices such as computers, printers, and servers. They enable effective communication between these devices, creating a network of shared resources.


There are two options: locally managed switches, ideal for high network control. And switches that are managed in the cloud, simplifying network management with automatic updates.


Routers


Routers connect multiple networks and devices to the Internet, allowing them to share a single connection. They act as distributors, choosing the best routes for data to travel.


In addition to connecting your company to the world, they protect against threats and prioritize traffic according to their settings. Routers with additional features such as firewall, VPN, and IP communications can make the network even more secure and efficient.


Access Points


Access points offer wireless connectivity, allowing devices to connect to the network without using cables. They expand bandwidth and provide flexibility for mobile workers.


In addition to extending Wi-Fi range, access points provide data about network devices and proactive security.


Wireless network


When creating wireless networks, you have three deployment options: centralized, converged, and in the cloud.


Centralized deployment is common in nearby locations, while converged deployment provides consistency between wired and wireless connections in smaller locations. Cloud deployment uses cloud management for local devices. Each option has its advantages, depending on your company's needs.


These essential network components play key roles in building a solid and secure network infrastructure. Choosing the right options for switches, routers, and access points can optimize your network connectivity and improve business productivity and efficiency.


External Networks: The Global Interconnection


Unlike internal networks, external networks are much larger and involve different types of agents.


However, there are also varied options for you to choose from. When planning a network infrastructure, you need to consider each one and make the final decision later.


Local Area Network (LAN)


Within an organization, local networks (LAN) are the most used. What characterizes a LAN are equipment and connections that operate within a single installation. Its main objective is connection to the external network and distribution of information internally.


Metropolitan Area Network (MAN)


Metropolitan Area Networks (MAN) cover larger areas, often encompassing multiple LANs in a city.


For this to happen, more robust infrastructure management and larger, more resistant equipment are required. After all, the distances that data travel are greater. Consequently, there is a greater risk of interference.


Wide Area Network (WAN)


Wide area networks (WAN) are even larger, connecting LANs and MANs. This type of technology is capable of covering vast geographic areas, such as entire countries or regions.


In this sense, as coverage is broad, data traffic is significant. As with MAN, there are more chances of interference. Therefore, a sophisticated infrastructure is required.


WAN projects are common in large and multinational companies with several branches.


Wireless networks (Wireless)


Back to the local level, wireless networks connect devices locally through data transmission via radio waves. Therefore, there is no need for physical cables.


Through routers, data is transmitted via radio waves and can be accessed by each device.


Therefore, when planning a wireless network, it is important to consider possible interference and the structure of the installation location. Issues to address include the location of the central router, the need for signal boosters, and which devices will use the network.


The Importance of Connectivity in the Digital Age


Connectivity plays a fundamental role in the digital era, driving advances in several areas. From business processes to services, smart cities and economies, digital connectivity is the backbone of contemporary society.


Therefore, disconnected people are at risk of exclusion from online opportunities that improve their quality of life. The same happens with companies that do not adapt to new technologies.


In this sense, structuring a good network to provide connectivity to people is essential. After all, this makes it possible to maintain communication and also find business opportunities.


Thus, investing in connectivity quality is related to the growth of organizations, as there is constant processing, storage and distribution of huge volumes of data.


In short, in the digital age, connectivity is the lifeblood that drives innovation, collaboration and access to information. Speed and latency are decisive criteria, as the ability to provide information quickly and efficiently is critical to success, and connectivity plays a central role in this process.


Connecting the Dots: Exploring Security, Management, and Types of Networks


Network connections are diverse, and can be characterized by size and also the final objective of their use.


When we think about the size of a network, we can consider the geographic area it occupies. It is also possible to measure the number of computers connected to this particular network.


A network can be small and keep only a few devices connected, or it can be very large and bring together millions of devices around the world.


Types of Network Connections


The evolution of internet connections is marked by a major change from dial-up to fiber optics. In this way, we can say that it is a technological revolution that has shaped how people work and communicate. Today it is impossible to think about the world and its connections without an available internet network.


Dial-up connection


The early days of the internet were characterized by dial-up, which used telephone lines to access the web. Although it was a great advance at the time, the high cost and limited connection speed of 56 Kbps made using the internet expensive and frustrating.


xDSL connection


The xDSL (Digital Subscriber Line) connection was an evolution. In this case, the telephone line was used for internet access, allowing phone calls and online browsing simultaneously. However, the slower upload speed was a drawback.


Broadband, radio and satellite Internet


Broadband internet marked a significant turning point in the world of network connections. After all, this option offered greater speed and stability, without depending on telephone lines. This included technologies such as radio internet, which uses radio waves to transmit data, and satellite internet, which offers broad global coverage.


Fiber-optic communication


The most recent innovation in this area is fiber optics. This network connection option allows for ultra-fast speeds. This is possible because beams of reflective glass are used. Furthermore, fiber optics transmits data at the speed of light, with high stability. To do this, it directly connects the data center to users' homes, minimizing data losses.


The way people interact with the digital world has changed and continues to change every day. Therefore, fast and reliable internet access is no longer a luxury, but a necessity in modern society.


And for this to happen safely, you need to understand how to protect data and devices.

Get to Know Your Enemy: Network Intrusion Techniques and Cybersecurity Strategies


Cybersecurity is increasingly a concern, which is why it is necessary to get to know network intrusion techniques. And beyond that, understand what the best cybersecurity strategies are and avoid damage.


This is because people's lives happen in the virtual environment, both personally and professionally.


Therefore, with the increase in cyber threats, it is essential that companies and individuals understand the profile of cyber attackers, their motivations, and the techniques they use to attack systems.


In this article, you will understand the complexities of cyber threats and the cybersecurity strategies that can be employed.


Introduction to Cyber Threats


In the current cybersecurity landscape, threats have evolved significantly. Cyberattacks are no longer isolated events, but a constant and evolving threat.


Therefore, the importance of knowing your enemy has never been more evident. Understanding who cyber attackers are, what their motivations are, and how they operate is critical to implementing an effective defense.


This type of attack is considered a crime, and there are people or even groups who seek to damage or destroy systems networks. This way, criminals are able to steal or expose sensitive data for misuse.


Profile of Cyber Attackers


Cyber attackers come in several categories, each with their own distinct characteristics.


Hackers


Hackers, for example, are cyber attackers often motivated by the desire to exploit vulnerabilities and gain access to systems for various purposes. Among them are data theft or simply demonstrating their skills.


Crackers


Although crackers share similar skills to hackers, they generally have malicious intentions. Thus, they aim to cause harm, disrupt systems, or obtain illegal benefits.


Insiders


Malicious insiders, on the other hand, are individuals who have legitimate access to systems and networks but use this position for criminal cyber activities. They may act motivated by personal reasons, dissatisfaction with the organization, or financial gain.


Furthermore, organized groups, often associated with cybercrime or cyberactivism, can conduct large-scale attacks with diverse motivations, from profit to political or ideological causes.


In this sense, understanding the diversity of attackers and the motivations behind attacks is crucial to developing effective cybersecurity strategies.


Network Intrusion Techniques


Just as there are different motivations for crimes, the techniques used also vary. Therefore, network intrusion can occur by exploiting software vulnerabilities, weak passwords, and even manipulation of information.


Among the most common tactics are brute force and dictionary attacks, in which attackers attempt to access systems by testing various password combinations.


Furthermore, the use of network scanning with techniques such as Spoofing can allow attackers to find vulnerable systems for future exploitation.


Understand each of the network intrusion techniques below.


Exploit Software Vulnerabilities


This attack happens when a criminal attempts or is able to break into a system, accessing confidential information. In addition, attacks against other computers also occur, causing a service to go offline.


Brute Force and Dictionary attacks


This network intrusion technique occurs when the username and password are guessed through trial and error. With access to the system, it is possible to carry out malicious actions.


This type of attack happens in companies, on social networks, in emails, and systems in general. Therefore, it is essential that your passwords are strong to avoid this type of situation as much as possible.


Network Scanning


On the other hand, the network intrusion technique called network scanning makes a thorough search of available networks. The objective is to find active computers on networks and collect information. This information includes the services and programs installed on the machine.


After this scan, criminals evaluate the results. With this type of attack, they are able to identify possible vulnerabilities in the detected services and programs.


Spoofing


Last but not least is the invasion technique called email spoofing. This type of attack is very common and happens when the header of an email is changed.


Thus, whoever receives the email believes they are receiving an official communication from a company, someone they know, or even the government.


However, the message is false and is used to infect devices such as computers, cell phones, and tablets with malicious links, sending spam and phishing attacks.


Cybersecurity Strategies


Now that you understand that there are numerous network intrusion techniques, it is essential to understand how to protect yourself.


Therefore, below you will learn about the best cybersecurity strategies for this type of attack.


Security Policies: The basis of defense


To effectively protect a network against cyber threats, a set of solid strategies is required. Well-defined security policies form the basis of defense, establishing guidelines for access and use of network resources.


If your company has a website and does not have security policies, you need to create them.


Security policies are guidelines, rules, and procedures defined by an organization. The goal is to protect your information systems, networks, digital assets, and data against cyber threats and security risks.


These policies establish a clear set of principles and practices that must be followed by employees, third parties, and, in some cases, even business partners.


And they can cover a wide variety of areas. Including the use of secure passwords, access restrictions, data encryption, monitoring network activities, and physical security practices, among others.


Identity and Access Management


Identity and access management ensures that only authorized people are allowed to access sensitive systems.


At this point, the company must have a strong culture regarding the security of who accesses what in the systems. Creating awareness among employees that each person is responsible for their individual login and password is very important. Likewise, having strong passwords is a great strategy.


Other important strategies


Continuous monitoring of networks and systems helps identify suspicious activity. At the same time, protecting sensitive data is crucial to keeping confidential information out of the hands of attackers. Finally, incident response is a fundamental cyber defense strategy, defining how to act when an attack occurs.


Towards a Safer Digital World


As cyber threats continue to evolve, it is essential that investments in cybersecurity technologies also advance. Cybersecurity is not a concern that will go away, but rather one that requires constant attention.


Therefore, investing in trustworthy security technologies and practices is the path to a safer digital world. Where even the most complex network invasion techniques will not work, as there are also defense strategies.


In this sense, companies and individuals can enjoy the benefits of technology without compromising security.


In conclusion, cybersecurity is an ongoing journey, and understanding threats and defense best practices are essential to protecting our digital assets.


EDR: An Essential Tool for Data Protection and Network Security


Protecting data and ensuring network security are essential issues for companies today. So, EDR (Endpoint Detection and Response) presents itself as an option to improve the protection and security situation in your company.


EDR is responsible for monitoring people's devices and understanding whether there are cyber threats targeting the data and network the device is connected to.


In this article, you will understand in detail about this technology and also the trends for the future. If you've never heard of EDR, it's time you understood this subject better and applied it to your business.


What is EDR and why is it important?


EDR is a solution for data protection and network security. This technology uses real-time analysis and automation with Artificial Intelligence (AI) to work.


The system's objective is to find cyber threats that are not detected by antivirus software. Furthermore, the technology is more advanced than other device security options, making it a good option for companies.


Using EDR, it is possible to improve the data protection of your company's customers, in addition to having more advanced network security. Increasingly, due to the advancement of existing threats, having an EDR solution in companies is essential in cybersecurity strategies.


How does EDR work?


EDR collects data from network endpoints constantly. These devices include computers, laptops, servers, cell phones, and devices connected to the Internet of Things, among others.


Once data is collected, the system is capable of analyzing it in real time. This way, it is possible to identify possible threats or suspicious behavior. So, with cyber threats identified, there is an automatic response to prevent or minimize the damage that these threats cause.


Therefore, the idea that EDR is just a tool for discovering devices on a network is a misconception. It has this feature, of course, but it also protects and acts against digital threats 24 hours a day, 7 days a week.


Characteristics of an EDR


There are differences between EDR tools, but some characteristics are common to all manufacturers.


Data collection


As you have already understood, any EDR technology will capture continuous data. This data can come from processes, performance, configuration changes, network connections, files, downloads, and behaviors of connected devices, among others.


Data is normally stored in the cloud, in a central database for better control. For data collection to happen, most EDR tools use a collection tool installed on each device.


Threat detection


To perform threat detection in real-time, the system uses advanced analysis technology and machine learning algorithms.


In this sense, threats fall into two categories: indicators of compromise (IOCs) and indicators of attack (IOAs). Indicators of compromise are actions or events with the potential for attack or data leakage. On the other hand, attack indicators are in fact associated with threats and cybercriminals.


In addition to an EDR tool, it is possible for a company to integrate it with other solutions related to network security. This way, all layers of the IT structure will be protected and monitored against threats.


Incident response


When an EDR tool is being used, one of the main features that helps businesses is that incident response is automatic.


This is possible because the system has rules pre-defined by the security team. Furthermore, as machine learning algorithms are part of the system, over time the EDR itself learns how to deal with various situations automatically.


Thus, when an incident occurs, security alerts are sent so that the correct actions are taken. Another advantage of the system is being able to identify and understand alerts according to the level of the incident.


Whenever necessary, affected devices will be disconnected from the network so that the protection of other ones is preserved.


These incident response, investigation, and remediation actions can be done through integrations with other systems. This increases data protection and network security significantly.


Advantages of EDR


Using an EDR tool is what improves the quality of your company's data protection. Likewise, it increases network security to keep devices away from cyber threats. Therefore, there are some important advantages to share with those who are interested in knowing more about the technology.


Reduced incident response time


With an EDR tool installed on your network, you will automatically have reduced incident response time.


This is one of the great objectives of this technology, after all, it improves the whole technology team’s work and avoids major problems for the company.


Therefore, as soon as an incident or threat alert is sent by the EDR, automatic actions begin to occur. Furthermore, the team responsible for network security is called in and the time to resolve the problem is reduced.


Improved security visibility


When network security solutions are basic, it is common for data and analysis to be stored and done in different locations.


Conversely, when an EDR is used, data collection, analysis, and reports are sent to a single system.


Consequently, the security team has a complete view of the network. This makes it possible to make better decisions for the company's security objectives and goals.


Cost reduction


When advantages such as productivity and time reduction exist in a system, cost reduction is a consequence.


In addition, by using an EDR, the company saves on different systems and platforms that would be necessary to ensure network security and data protection throughout the infrastructure.


Taking this into consideration, choosing a single tool to perform all roles within data protection and network security is essential. Therefore, choosing EDR is a very advantageous business decision both in terms of results achieved and the value invested.


The Future of EDR: Trends and Evolution


EDR is increasingly being used by companies as a cyber defense tool. When in operation, the tool records suspicious activities and acts to stop the action. However, there are even more advanced technologies in the area of data protection and network security.


One example is the so-called XDRs, which is the next step in the EDR concept. With this innovative tool, it is possible to create a complete chain of protection. Thus, XDR helps control threats at different points in the chain.


The tendency, therefore, is for more and more sophisticated systems to be used on the market.


This does not change the reality of EDR use by companies, which is a complete and useful tool for companies. However, it is essential to always be aware of news in the area, so that safety always comes first.
