June 7, 2025In the modern digital society, information technology is developing rapidly. Computerization in the economy and in every person's life makes user data vulnerable. Information can be modified, deleted or stolen. It is one of the most important resources for any company, organization or enterprise, and therefore must be securely protected. A properly designed information security system prevents unauthorized access, leaks or data modification.
What is Information Security
Information security of data is a set of measures and technologies that protect it from any unauthorized access, modification, and theft. They are specifically designed to withstand targeted and mass attacks. They allow not only timely response to them but also prevention. With a properly built information security system, all its elements are resistant to any threats.
Information security or IS is based on three main principles:
- Confidentiality implies that only the user or those who need it to perform their duties in the company have access to the information. For this, permission can be obtained, but there must be a guarantee that no outsiders can study the data.
- Integrity of information is important for its preservation. Data must be accurate, protected from accidental or malicious distortion. Their modification should be available only to the owners. And in an organization, an employee should only have access to the information required for their work.
- Availability is another important principle of IS. Information at any time and in full must be available to the user or those who have permission. Therefore, data carriers must be protected from failures and cyberattacks.
In the era of digital technology, cybersecurity or electronic security is important. It ensures the protection of computer systems from viruses, phishing, hacker attacks, and malicious software. IS differs from cybersecurity in that it is a broader concept. It protects data from both technologies and people. IS is the protection of information not only in electronic form but also on physical media. This includes preservation, management procedures, compliance with legislation, reputation protection, and ensuring business continuity.
What Information Protection Includes
Russian legislation defines how information about individuals or companies should be properly stored. Users should have free access to it, but the data must be protected from viruses, hackers, and other external threats.
The primary goal of information security is to prevent unauthorized access to personal or corporate data. This data must be safeguarded against leaks, deletion, and tampering. The types of data requiring protection include:
- Personal information: Passport numbers, phone numbers, addresses, health records, employment details, and educational background.
- Banking data of individuals and companies: Card numbers, account details, and other financial information.
- Confidential information and corporate intellectual property: Trade secrets, developments, patents, business plans, and copyrights.
- System and infrastructure information: Server data, network devices, configurations, logs, and access keys.
Even publicly available information requires protection. While it may be freely accessible online, there must be guarantees that no one can delete or alter it.
What Can Happen Without Protection
Nowadays almost all information about individuals and companies is stored digitally. Therefore information security protection is required in all spheres of human activity. It is especially important for government structures, financial sector, healthcare, telecommunications, and business. The government protects state secrets, information about national defense capabilities, and infrastructure. Operations of power plants, nuclear power stations and other critical facilities must not be disrupted by hacker attacks. Information about enterprise production processes and people's personal data must not become publicly available.
Without reliable protection, personal and corporate data face various threats. It may be altered or deleted. For companies, damage from information security breaches leads to serious problems. This could range from minor financial losses to complete termination of operations. Loss of customer data negatively affects profits. And if a company fails to provide financial reports, this will result in fines. The danger also lies in the fact that information leaks may not have immediate consequences. Disclosure of data will damage the company's reputation, leading to decreased profits.
Where do the threats come from
Universal computerization and new technologies make data storage easier and provide new opportunities. But they create additional risks and make information vulnerable. Threats to information security can be natural or artificial. The former are independent of humans and represent information corruption due to disasters, accidents, and natural disasters. Artificial threats can be intentional or accidental, which are committed through negligence or ignorance.
There are such types of artificial threats:
- unauthorized access – when criminals hack into a company's servers or a user's email;
- integrity violation – accidental or intentional modification of data;
- leakage of confidential information, its distribution on the web or among competitors.
Viruses, phishing, user errors
The main sources of threats in modern cyberspace are malware. It includes viruses, Trojans, and other spyware that enter your computer in various ways. They can damage or delete information, provide access to data for intruders, or disrupt the operation of the device. Such programs get into the computer through emails, links, files.
Phishing is one of the types of cyber threats. This is a substitution of a real application, service, or website for a fraudulent one to steal information. A user visits such a site and enters their data there: passwords, bank card or passport data. Psychological techniques are used to force him to do this. The attackers then use the stolen data on this resource or sell it.
Information leakage can occur due to errors or careless actions of users. These are the loss of a mobile phone, missing documents, and clicking on unverified links. Data leakage can be caused by the lack of regular software updates, the use of simple passwords, and the transmission of secret information in unencrypted form by email or messenger.
External and internal causes
The reasons for information security breaches can be external or internal. External threats that are used by hackers and criminals are more common. These include:
- A DDoS attack leads to an overload and shutdown of the server;
- an exploit is an imperfection of the system, a vulnerability in the software that allows fraudsters to gain access to data;
- psychological impact on users: intimidation, bait, seduction in order to obtain information or access accounts;
- interception of confidential information by intruders during its transmission;
- Advanced Persistent Threat (APT) – regular, persistent attacks.
Internal threats are also possible at any enterprise or company. The source may be employees who have access to the information. They may use it for selfish purposes or leak it unintentionally, in violation of security requirements. Such threats include sabotage and data leakage.
Many employees use their work computers for personal purposes: they correspond, run games and applications, and visit third-party websites. They have no purpose to damage the data, but their actions lead to the penetration of malware into the system. Another category of employees steals information for personal gain. These are mostly executives who have access to corporate secrets and pass them on to competitors. They may also be fired employees who want revenge and sell information they know.
What difficulties prevent you from protecting your information?
It is difficult to protect information due to developing technologies and the human factor. Cybercrime is improving, and new viruses and malware are emerging. And outdated equipment cannot withstand such attacks. The human factor occupies one of the first places in the violation of security. This is due to employees' ignorance, negligence, and unwillingness to comply with complex rules. Some people are easily manipulated and reveal classified information. Another difficulty that arises during protection is the large amount of information.
How can I protect myself
Technical, programmatic, and organizational methods are used for protection.
Passwords, antiviruses, backups
The technical and software tools of information security include encryption, the use of proven firewalls. It is important to use intrusion detection technology (IDS) and Intrusion Prevention System (IPS) to monitor network traffic. They monitor threats and respond to them automatically. The DLP system prevents data leakage in the form of sending by mail, printing documents. A VPN protects your Internet connection and encrypts it when transferring data. It is also important to use long passwords that include letters, numbers, and symbols. It is better to create separate passwords for different accounts, which are stored in a special manager.
Antivirus programs are an effective means of protection. It can be Norton, McAfee, Kaspersky or others. They monitor malware, viruses, and spyware and prevent them from entering the system. There are programs for monitoring and scanning the system for vulnerabilities. It is also recommended to make backups for all important files, which will help restore the data. They need to be updated regularly and stored in a safe place.
Rules for home and office
Information security rules must be observed by all employees of the company. They are also important for home digital devices. The main rule is not to open emails, websites that seem suspicious, do not follow unverified links, do not download suspicious files, and do not insert unknown flash drives into your computer. You can verify the site's reliability by checking its SSL certificate. You also need to set a password to log in to your computer and mobile phone, and do not leave them unattended where they can be stolen.
Who is involved in security
Companies, organizations, and businesses hire professionals to protect confidential information.
Specialists, hackers, and forensics
In large organizations, information security is a complex and complex process. This needs to be done all the time, so it's better to entrust such work to a specialist. He must have knowledge of information security and know how to protect himself. The purpose of his work is to preserve information, ensure the integrity of the corporate system and minimize losses in case of leakage. It constantly monitors all actions on the local network and can respond in time to unauthorized copying, modification or deletion of files. The tasks of an information security specialist include:
- analysis of possible threats;
- develop rules to help reduce the risk of data loss;
- configuring software that will repel attacks;
- Information access management;
- training of company employees;
- System recovery after failures;
- Monitoring compliance with legislation.
The company can also hire temporary specialists. For example, hackers are exploring software features, installing antiviruses, and developing new protection methods. They detect and eliminate vulnerabilities. If a leak has already occurred, a forensics specialist or a computer criminologist is hired. It will help to identify the source of the leak, restore deleted correspondence and malicious codes.
Does an ordinary person need to know all this?
Information security rules are important not only for companies, but also for ordinary people. Data leakage brings serious problems to the user: money can be stolen from a card or account, an attacker can apply for a loan in his name, information can be used for fraud or blackmail.
Recommendations for the reader: what to do now
If the device does not have information security, it is vulnerable. Simple tips can help you avoid data leaks:
- Use complex passwords;
- regularly update the software to the latest versions, as important security patches are embedded in them.;
