Network firewalls are one of the oldest and most effective mechanisms for protecting computer networks.
Their task is to monitor and control traffic between the internal network (e.g., corporate) and the external one (e.g., the Internet).
It is the firewall that decides which connections are safe and which should be blocked.

Phishing is one of the most widespread cyberattack techniques today. Cybercriminals impersonate trusted entities (banks, courier companies, government offices, or even your CEO) to steal login credentials, passwords, credit-card details, or other sensitive data.
The method is simple – yet it remains extremely effective because it exploits the human factor.

Network security is the first line of defence against cyberattacks.
It’s not just technology — it’s a set of disciplined practices that protect company data, customer information, and IT infrastructure from breaches and downtime.
Why Network Security Matters A secure network:
shields data and systems from external and internal threats, guarantees business continuity, minimises financial and reputational damage. Even a small oversight — a weak password or a missed patch — can open the door to a devastating incident.

Encryption is the foundation of information protection in the digital age.
Whether it’s personal data, customer records, or trade secrets, encryption ensures that even if data falls into the wrong hands, it remains unreadable and useless without the proper key.
What Is Data Encryption? Encryption is the process of converting readable data into an unreadable cipher using mathematical algorithms.
Only authorised parties possessing the correct decryption key can revert it to its original form.

Ransomware is malicious software that encrypts victim’s files or entire systems and then demands a ransom for the decryption key.
It remains one of the most severe and disruptive threats in the modern IT landscape — capable of paralysing companies, public institutions, hospitals, and even entire cities.
What Is Ransomware? Ransomware is a type of malware that blocks access to data or systems by encrypting them.
After infection, the victim receives a ransom note demanding payment (usually in cryptocurrency) in exchange for the decryption key.

As everyday life becomes increasingly digitised, more and more court cases rely on electronic evidence – information stored in digital form.
Yet Poland still lacks uniform regulations and standards governing how such evidence is secured, analysed, and preserved.
The issue was first raised in the Polish Parliament in 2009 through parliamentary question No. 7857 (submitted by MP Krzysztof Brejza) addressed to the Minister of Justice. The question highlighted the urgent need for unified procedures and higher qualification requirements for court-appointed IT experts.
