With the rapid growth of data exchange on the Internet, information security is becoming one of the key issues for both individuals and organizations. Internet technologies, providing enormous opportunities for communication and data exchange, simultaneously open up new opportunities for cybercriminals seeking to gain unauthorized access to confidential information. As a result, the need to develop reliable data protection solutions increases.
The relevance of the problem lies in the fact that with the expansion of digital technologies and a significant increase in the volume of data transmitted over the Internet, the number of cyberattacks aimed at compromising, stealing or destroying information has increased. Over the past few years, there has been a significant increase in the number of incidents related to cybercrime. Modern technologies, such as artificial intelligence and automation, are also used to complicate attacks and bypass existing security systems[1].
With the mass transition to remote work and the active use of cloud services for data transfer, new vulnerabilities arise, which requires strengthening measures to protect information, which makes this problem extremely relevant.
The purpose of the article is to analyze modern means and methods of information protection on the Internet, as well as to assess their effectiveness.
Research objectives:
• To study existing methods of information protection in network structures.
• To describe the main tools and technologies used to ensure cybersecurity.
• To analyze the pros and cons of various protection methods and to offer recommendations for their improvement.
The history of information security is closely linked to the development of technology and the emergence of new security threats. Initially, data protection methods were based on primitive ciphers, such as the Caesar cipher, which was used in ancient Rome to protect secret messages. During World War II, more complex encryption systems, such as the Enigma machine, entered the arena, which became an important milestone in the history of information security.
With the development of computing technology and computer networks in the 20th century, new challenges arose. In 1977, the US adopted the Data Encryption Standard (DES) encryption standard, which was widely used to protect information in government and commercial areas.
However, as computing power increased, DES became vulnerable to attacks, and in the early 2000s it was replaced by the more reliable AES (Advanced Encryption Standard).
The emergence of the Internet in the 1980s and 1990s gave rise to the need to create more advanced means of protecting data when transmitted over networks. During this time, technologies such as SSL/TLS for securing connections and PGP (Pretty Good Privacy) for encrypting emails were developed. At the same time, antivirus programs and firewalls emerged to combat new threats such as viruses and Trojans[2].
In the 2000s, with the increase in the number of cyberattacks, intrusion detection systems (IDS) and antivirus software were actively developed. The spread of cloud technologies and mobile devices increased the demand for solutions for protecting data in distributed systems.
In the 2010s, with the advent of the Internet of Things (IoT) and cloud services, information security tools became even more complex. During this period, technologies such as multi-factor authentication, identity and access management (IAM), and data encryption at all levels of the infrastructure became widespread.
Modern approaches to data protection include the use of artificial intelligence and machine learning to detect threats, as well as the use of blockchain technologies to ensure the security and integrity of data. The development of these technologies continues to respond to the challenges of new cyber threats and security requirements.
Methods of protecting information on the Internet play an important role in preventing cyberattacks, ensuring the confidentiality and integrity of data, and protecting it from unauthorized access. Let's look at the main methods that are used for these purposes:
1. Data encryption. Encryption is one of the most effective methods of protecting information. It converts data into an encrypted format that becomes unreadable to unauthorized persons. There are different types of encryption, such as symmetric and asymmetric encryption. Symmetric methods, such as AES algorithms, use a single key to encrypt and decrypt data. Asymmetric methods, such as RSA, involve the use of a pair of keys: public and private.
2. Authentication and identification of users. Authentication ensures that only authorized users have access to the system. The most common method is password verification, but multi-factor authentication (MFA) is increasingly used to improve security. In this case, in addition to the password, the user must confirm their identity using additional factors, such as one-time codes or biometric data (fingerprint scanning or facial recognition).
3. Firewalls. Firewalls are software or hardware that monitor and filter incoming and outgoing network traffic. They prevent access to unauthorized resources and block possible threats. Modern firewalls can analyze the content of traffic and detect intrusion attempts.
4. VPN (Virtual Private Networks). VPN creates an encrypted channel between the user and the remote server, which protects data from interception on public networks. VPN is an important means of protection when working with confidential information over the Internet, as it encrypts all transmitted data[3].
5. Antivirus software. Antiviruses provide protection against malware that can damage or steal data. Antivirus programs automatically scan files, check them for threats, and eliminate any threats found. Regular updates of antivirus databases are necessary to protect against new viruses.
6. Intrusion Detection and Prevention Systems (IDS and IPS). These systems monitor network traffic and can detect suspicious activity. IDS (Intrusion Detection System) analyzes traffic and signals possible threats, while IPS (Intrusion Prevention System) can automatically block such threats.
7. Access control. Restricting access rights is another important method of information protection. Using role-based access control (RBAC) models allows you to control who can access what data. This method minimizes the risks associated with unauthorized access or information leakage.
8. Spam and phishing detection and filtering. Filters for mail systems can recognize malicious messages and links, preventing phishing attacks and protecting against malware infection.

These methods of information protection are used comprehensively to ensure maximum data security on the Internet. The development of technologies and the emergence of new threats require constant improvement of protective means to counter modern challenges in the field of information security[4].
Modern data protection tools play a crucial role in the face of increasing cyber threats and the need to securely store and transmit information. Various protection methods include both technical and organizational measures to ensure the confidentiality, integrity, and availability of data. Let's look at several key solutions used in practice to protect data on the Internet:
1. Data encryption. Encryption is used to protect information both during transmission and storage. For example, the HTTPS protocol provides a secure connection between a web server and a browser, which is especially important for online transactions and protecting confidential information. Disk encryption programs such as BitLocker for Windows or FileVault for macOS protect data on a device in the event of its loss or theft.
2. Multi-factor authentication (MFA). Multi-factor authentication adds an additional layer of security when logging in. This can be a one-time code sent to your phone, the use of authenticator apps, or biometric data. Examples of successful implementation of MFA can be seen in services provided by Google and Microsoft, where users are offered additional protection for their accounts.
3. Firewalls and intrusion prevention systems. Firewalls, such as pfSense and Cisco ASA, filter incoming and outgoing traffic to prevent unauthorized access. In addition, intrusion detection and prevention systems (IDS/IPS), such as Snort or Suricata, are used to monitor suspicious activity on the network and prevent possible attacks.
4. VPN and traffic anonymization. With the help of VPN services (for example, NordVPN or ExpressVPN), users can hide their Internet activity and encrypt data, especially when using public Wi-Fi networks. This solution is important for ensuring the security of personal information and protecting corporate data in remote work.
5. Email security systems. Email remains one of the most frequently attacked systems, so solutions such as Proofpoint or Barracuda Email Security Gateway are used to protect it, filtering messages from malicious links and attachments, and preventing phishing.
6. Antivirus software. Modern antivirus programs such as Kaspersky, Norton, McAfee protect against viruses and other threats, including spyware and malicious downloads. They play an important role in preventing attacks on computers of both private users and companies.
7. Backup systems. Backup programs such as Acronis and Veeam help to create backup copies of data and quickly restore them in case of ransomware attacks or technical failures. Such solutions are especially important for enterprises to minimize data loss.
Each of these protection tools helps reduce the risk of leaks and attacks on information, ensuring its safety and protection on the Internet.
With the development of digital technologies, there are more and more opportunities to protect information on the Internet. However, along with this, new challenges arise that require the implementation of more advanced protection methods[5].
Potential for further development
1. Artificial intelligence (AI) and machine learning: In the future, AI will become an important component of security systems. Using AI to monitor networks, analyze data, and automatically detect threats will allow you to identify anomalies and respond to incidents faster. Machine learning will help predict possible attacks and neutralize them before they cause damage.
2. Quantum cryptography: Quantum cryptography technologies represent a revolution in the field of data protection. Unlike traditional encryption methods, quantum cryptography uses the laws of quantum mechanics, which ensures almost absolute security of data transmission. Despite the high cost of development, quantum solutions promise to radically change approaches to information protection.
3. Internet of Things (IoT): With the increasing number of devices connected to the network, IoT security is becoming a priority. Innovative solutions for securing IoT networks include blockchain technologies and decentralized protocols that can ensure data security at the device and network level.
4. Biometric Authentication: Biometric methods such as fingerprints or iris scanning are becoming more popular. Their improvement will significantly improve the security of access to information and minimize the risk of hacks based on traditional passwords.
Growing Threats
1. Rising Cybercrime: Cybercrimes such as hacking, fraud, and espionage are becoming increasingly sophisticated. Criminals use new methods and technologies, which requires constant improvement of security systems.
2. AI as an Attack Tool: Attackers can use AI to analyze security systems and find their weaknesses. With the help of AI, highly effective phishing attacks and other types of cyberattacks can be created that are difficult to detect using traditional methods.
3. Quantum Computers: With the advent of quantum computers, most current encryption algorithms may become obsolete. This poses a serious threat to the global data security infrastructure, requiring the development of new quantum-resistant cryptographic methods.
4. Ransomware: Ransomware continues to evolve and its spread is increasing with the increase in the number of connected devices and cloud services. Malware can attack both individual users and entire organizations, blocking access to data and demanding a ransom for its recovery.
Thus, the future of information security lies in the development of new technologies and methods that can counter growing threats. In parallel with the implementation of new solutions, it is necessary to take into account the evolution of cyberattacks and adapt defense strategies to maintain a high level of data security on the Internet[6,8].
With the rapid growth of cyberattacks and the increase in the volume of data transmitted over the Internet, information security issues are becoming especially relevant. The article analyzed key methods and means of information protection that help cope with modern challenges, as well as protect the data of both individual users and large organizations.
Current information security solutions, such as encryption methods, two-factor authentication, the use of VPNs, firewalls and intrusion detection systems, have demonstrated high efficiency in preventing threats. At the same time, the introduction of the latest technologies, including blockchain, artificial intelligence and quantum cryptography, opens up new prospects for data protection. These technologies help to form more complex and reliable means of countering cyberattacks, creating additional barriers for intruders[7].
However, with technological progress, new threats arise. For example, the mass distribution of Internet of Things (IoT) devices and quantum computing poses new challenges in the field of cybersecurity. Insufficient protection of IoT devices makes them vulnerable to attacks, and quantum computers have the potential to crack existing cryptographic systems, which forces developers to look for new solutions to protect data in the future.
To ensure reliable data protection, it is necessary not only to implement modern protection methods, but also to adapt them to changing conditions. It is important to raise user awareness of cyber threats, since the human factor remains one of the weakest points of information security.
Thus, the development of information security tools should include not only technological innovations, but also constant adaptation to new threats and challenges. Improving cyber literacy and implementing modern technologies will ensure effective data protection in the context of increasing cyber threats and digitalization in the future.
