Bezpečnost

Bezpečnost (or „security“ in English) in computer science refers to the measures and practices implemented to protect computer systems, networks, and data from unauthorized access, attacks, damage, or theft. It encompasses a wide range of processes and technologies aimed at ensuring the confidentiality, integrity, and availability of information.

Key components of computer security include:

1. **Authentication**: Verifying the identity of a user or system before granting access to resources.
2. **Authorization**: Defining what an authenticated user can do within the system, including access controls and permissions.
3. **Encryption**: Encoding data to prevent unauthorized access, ensuring that even if data is intercepted, it cannot be read without the proper decryption key.
4. **Integrity**: Ensuring that data is not altered or tampered with, often using checksums and cryptographic hashes.
5. **Network Security**: Protecting the integrity and usability of network and data by implementing firewalls, intrusion detection systems, and secure communication protocols.
6. **Risk Management**: Identifying, assessing, and prioritizing security risks to implement appropriate measures to mitigate them.

Overall, bezpečnost is a critical aspect of information technology, reflecting the need to safeguard sensitive information and maintain trust in digital systems.
