What is cyber security in the context of data storage?
Cyber security in the context of data storage is much more than protection against cyber attacks. It’s a comprehensive system of safeguards, procedures and practices that together create a multi-layered protection of corporate information. A key element is maintaining the three basic aspects of security: confidentiality, integrity and availability of data.
In practice, this means implementing appropriate access control mechanisms, encrypting data at rest and during transmission, and ensuring business continuity through backup systems. According to “The State of Data Security” report published by Thales Group in January 2024, as many as 83% of enterprises have experienced at least one data security incident in the past year.
A modern approach to cybersecurity also requires taking into account the peculiarities of hybrid work and the growing number of mobile devices in the corporate environment. Data security must be flexible and scalable to meet dynamically changing business needs.

What are the main threats to data security in IT infrastructure?
Today’s data security threats are increasingly sophisticated and often combine different attack vectors. Based on the experience of nFlo’s security audits, we can distinguish three main categories of threats:
Attacks targeting infrastructure often exploit security vulnerabilities in systems and applications. Particularly dangerous are zero-day attacks, against which traditional security systems can be ineffective. Regular penetration testing and system updates are key here.
Insider threats, from employees or contractors, account for about 60% of all security incidents, according to Ponemon Institute research. They are often the result of ignorance or negligence, less often of intentional action.
Social engineering attacks, particularly phishing and its more sophisticated forms like spear-phishing and whaling, remain among the most effective methods of gaining unauthorized access to corporate data.
Where to store backups to keep them safe?
In the context of backup storage, the 3-2-1 rule is key: you should have three copies of your data stored on two different media, with one copy in an offsite location. This strategy works for both small businesses and large corporations.
When selecting a location for backups, consider: Physical security of the location, including protection from natural hazards and physical access to the server room. The data center should meet strict security requirements, with redundant power and cooling systems and 24/7 monitoring.
Availability of data in the event of a disaster is a key factor in choosing a backup location. Adequate Internet bandwidth and the ability to quickly physically access media in emergency situations should be ensured.
Storage and data transfer costs must be balanced with business requirements. It is worth considering the various pricing models offered by service providers, taking into account not only the cost of disk space, but also data transfer fees or additional backup as a service.
For example, for companies in the financial sector, we often recommend a hybrid model, where critical data is stored locally and backed up in a certified data center that meets regulatory requirements. This approach provides an optimal balance between security, availability and cost.
What types of data require special protection in a company?
In a business environment, not all data requires the same level of protection. It is crucial to understand the different categories of data and tailor security measures to their sensitivity. Based on our experience with security implementations in various sectors, we can highlight several key categories of data that require special protection.
Employees “and customers” personal information is strictly protected under the RODO. This includes not only basic identification data, but also information on salaries, employee evaluations or employment history. For this data, it is necessary to implement advanced access control and encryption mechanisms.
A company’s intellectual property, including source code, technical documentation and product development plans, requires particularly strong security due to their strategic importance to the organization. Data Loss Prevention (DLP) systems combined with advanced access monitoring are often used here.
Financial and accounting data, including transaction information, financial statements or tax data, require not only protection from unauthorized access, but also the preservation of its integrity and the ability to audit all operations.
Where to store company data - locally or in the cloud?
Choosing between storing data locally or in the cloud is one of the key decisions affecting a company’s information security. Each solution has its own advantages and limitations, which should be weighed against the specifics of the organization.
Local storage gives full control over infrastructure and data, which is particularly important for companies in regulated sectors. However, it requires significant investment in hardware, physical security and IT staff. Based on our implementations, we observe that the cost of maintaining an in-house data center can be up to three times higher than cloud solutions.
The cloud offers greater flexibility, scalability and often higher levels of service availability. Leading public cloud providers, such as AWS and Azure, provide advanced security mechanisms and compliance with most industry standards. However, using the cloud requires special attention to security configuration and access management.
More and more organizations are opting for a hybrid model, where some data is stored locally and some in the cloud. This approach optimizes costs while maintaining a high level of security.
What is data encryption and how does it affect storage security?
Encryption is a fundamental layer of data protection, transforming information into a format that is unreadable by unauthorized parties. In business practice, there are several key application areas for encryption.
Data at rest (data encryption) secures information stored on disks and other media. This typically uses AES-256 or similar standards, providing a high level of security with an acceptable impact on performance.
Data-in-transit encryption protects information as it is transferred between systems. The standard here is the TLS 1.3 protocol, which eliminates known vulnerabilities of earlier versions and provides strong protection for communications.
Proper management of encryption keys is particularly important. We recommend implementing dedicated key management systems (KMS) that provide secure key storage and rotation, as well as full control over the key lifecycle.
What authentication and authorization mechanisms are worth implementing?
Effective authentication and authorization mechanisms are the first line of defense in protecting corporate data. In the current business environment, traditional passwords do not provide a sufficient level of security. It is necessary to implement multi-factor authentication (MFA) and advanced identity management mechanisms.
Multi-component authentication should use at least two different factors from three categories: something the user knows (password), something the user has (hardware token or mobile app), and something the user is (biometrics). In corporate environments, solutions based on the FIDO2 standard are particularly effective in eliminating phishing risks.
Identity and access management (IAM) systems should enable centralized privilege management and automation of processes for granting and revoking access. Consider implementing solutions based on the OAuth 2.0 protocol and OpenID Connect, which provide secure delegation of privileges between systems.
How to manage user permissions to corporate data?
Privilege management is an ongoing process that requires regular review and updating. The basis is the implementation of the Principle of Least Privilege, according to which users are given only those privileges that are necessary to perform their job duties.
In practice, this means implementing a hierarchical system of roles and permissions, where access to data is assigned based on position and specific business needs. The system should allow for granular privilege management, with the ability to temporarily delegate access and automatically extinguish unused accounts.
Special attention should be paid to privileged (administrator) accounts, which should be subject to additional safeguards, such as regular auditing of activities or the requirement that a second person approve critical operations (the four-eyes rule).
What is backup and why is it crucial to data security?
Backups are the last line of defense against data loss, whether due to hardware failure, human error or ransomware attack. An effective backup strategy must include not only regular backups, but also verification and the ability to quickly restore them.
It is crucial to understand the difference between data synchronization and true backup. Synchronization (e.g., via cloud services) does not protect against accidental deletion or encryption by ransomware, as changes are immediately replicated to all copies. True backup requires storing multiple historical versions and protecting against unauthorized changes.
Which backup strategies are most effective?
In an enterprise environment, a layered strategy that combines different types of backup works well:
Incremental backup performed on a daily basis allows quick recovery of the latest changes with minimal load on the infrastructure. The use of block-level incremental backup technology significantly reduces the amount of data transferred.
Differential backup, performed once a week, simplifies the restoration process by requiring only two sets of data: a full baseline backup and the latest differential copy.
A full backup, performed once a month, provides a baseline for incremental and differential copies. Consider using deduplication at the source level, which significantly reduces disk space requirements.
How to recover data from a backup in case of a disaster?
The recovery process requires a systematic approach and advance preparation. Regular testing of restoration procedures is key, preferably in a test environment that mirrors production. This allows not only to verify the integrity of backups, but also to estimate the actual time needed to restore systems. In addition, regular testing helps the IT team become familiar with the procedures and identify potential problems before they occur in an emergency.
In the event of a major failure, it makes sense to use a prioritization approach. Business-critical systems are restored first, followed by support systems, and finally archived data. This strategy minimizes downtime and restores critical business functions faster. The recovery plan should include clearly defined success criteria for each stage of the process and defined decision points.
An important part of the recovery process is proper documentation. Each step of the process should be documented in detail, including duration, problems encountered and solutions applied. This documentation is invaluable for optimizing procedures and training new team members. It is also a good idea to keep a real-time recovery log, which will help in later analysis and improvement of procedures.
What are the most important data security standards and regulations?
In today’s complex regulatory environment, organizations must comply with a range of data protection requirements. The RODO is the primary piece of legislation governing the processing of personal data in the European Union, but it is only the tip of the iceberg. Regulated industries, such as finance or healthcare, are subject to additional requirements specific to their sector.
ISO 27001 establishes an international standard for information security management systems. Its implementation requires a systematic approach to security management, including identification of threats, risk assessment and implementation of appropriate safeguards. ISO 27001 certification is often required by corporate clients and provides evidence of an organization’s information security maturity.
The PCI DSS (Payment Card Industry Data Security Standard) is of particular importance for companies processing payment card data. It specifies the detailed technical and organizational requirements for secure processing of payment data. It is worth noting that PCI DSS requirements are regularly updated in response to new threats and changing technologies.
The TISAX (Trusted Information Security Assessment Exchange) standard, which was developed by the German automotive industry association VDA, is becoming increasingly important in the automotive sector. It defines security requirements for suppliers in the automotive industry and is often required when working with leading automakers.
How does RODO affect the storage of personal data in a company?
The RODO introduces a comprehensive approach to personal data protection, requiring organizations to implement appropriate technical and organizational measures. A key aspect is the principle of privacy by design, which means taking privacy protection into account from the design stage of systems and processes. This requires careful planning of IT systems architecture and data processing procedures.
Special attention should be paid to the legal basis for data processing and the realization of data subjects’ rights. Organizations must be able to quickly locate and make data available at the request of the data subject, as well as ensure that data can be deleted or transferred. This requires proper organization of databases and information management systems.
Data breach notification is also an important requirement of the RODO. Organizations have only 72 hours to report a serious breach to the supervisory authority. This means implementing effective systems for monitoring and detecting security incidents and clear procedures for responding to breaches.
In practice, compliance with the RODO requires regular employee training, updating security policies and maintaining detailed documentation of data processing processes. It is particularly important to maintain a register of processing activities and regularly conduct data protection impact assessments (DPIAs) for high-risk processes.

What are the key technologies for data encryption in IT infrastructure?
In a modern IT infrastructure, data encryption relies on several key technologies that together form a comprehensive information protection system. At its core is disk-level encryption (FDE - Full Disk Encryption), which secures the entire contents of storage media. In a Windows environment, the most popular solution is BitLocker, while Linux systems often use LUKS (Linux Unified Key Setup). Both solutions use advanced encryption algorithms, such as AES-256, providing a high level of security with minimal impact on system performance.
File and folder level encryption (FLE) is another important feature. This technology allows for selective security of specific data, which is particularly useful in environments where different users have access to shared resources. Solutions such as Microsoft EFS (Encrypting File System) or the open-source VeraCrypt, which allow the creation of encrypted data containers, work well in corporate environments.
Encryption in data transmission is mainly based on the TLS 1.3 protocol, which replaced older versions of SSL/TLS. This protocol uses advanced cryptographic mechanisms to ensure the confidentiality and integrity of transmitted data. For VPNs, solutions based on the WireGuard and OpenVPN protocols are gaining popularity, offering an excellent balance between security and performance.
Encryption plays a particularly important role in cloud environments. Leading cloud providers offer advanced encryption systems for both stored (at rest) and transmitted (in transit) data. In doing so, they use dedicated HSM (Hardware Security Module) modules to securely store encryption keys.
How do you choose the right encryption solution for your business?
Choosing the right encryption solution should start with a thorough analysis of the organization’s needs and the specifics of the data being processed. Consider not only security requirements, but also the impact on system performance, ease of management, and implementation and maintenance costs. It is also crucial to consider industry-specific regulatory requirements - for example, companies in the financial or medical sectors must meet more stringent standards.
In the context of local infrastructure, it is worth considering solutions that offer central management of encryption keys (KMS - Key Management System). This allows efficient management of access to encrypted data across the organization and facilitates key rotation processes. A good example is Microsoft Azure Key Vault, which can be integrated into both cloud and on-premises infrastructures.
For organizations using different platforms and operating systems, interoperability of encryption solutions is important. It makes sense to choose solutions that support standard key and certificate formats and offer APIs for integration with existing systems. It is also important to make sure that the chosen solution allows easy recovery of encrypted data in case of key loss or system failure.
For companies considering migrating to the cloud, it is particularly important to choose a solution that will work effectively in both on-premises and cloud environments. It’s worth considering systems that offer BYOK (Bring Your Own Key) functionality, which allows you to retain full control over your encryption keys even when using cloud services.
What role does access control play in data protection?
Access control is a fundamental component of a data protection system, acting as the first line of defense against unauthorized access. In modern organizations, the access control system must be multi-layered, combining physical security with logical control mechanisms. The cornerstone is the implementation of the Zero Trust model, which involves verifying every attempt to access resources, whether it comes from inside or outside the organization.
A key element of effective access control is the implementation of an Identity and Access Management (IAM) system. This system should include not only employees, but also contractors, business partners and automated systems. It is also important to implement Single Sign-On (SSO) and identity federation mechanisms that facilitate access management in hybrid and multi-cloud environments.
Special attention should be paid to Privileged Access Management (PAM) controls. Accounts with elevated privileges are an attractive target for attackers, so they require additional safeguards. This includes the use of just-in-time privileged access, where elevated privileges are granted only for the duration of a specific task, and detailed monitoring and auditing of all activities performed with privileged accounts.
In the context of sensitive data, it is important to implement access control mechanisms at the data level (DAC - Data Access Control). This allows granular management of access to specific information, regardless of its location or format. DAC systems should take into account not only the roles of users, but also the context of access, such as time of day, location or device used.
Effective protection of corporate data requires a comprehensive approach, combining appropriate technical solutions with proper organizational procedures and informed employees. In today’s business environment, where cyber threats are becoming more and more sophisticated, it is crucial not only to implement the right safeguards, but also to regularly update and adapt them to changing conditions.
