Bezpečnost

Bezpečnost (Security) in computer science refers to the measures and protocols put in place to protect computer systems, networks, and data from unauthorized access, attacks, damage, or theft. It encompasses a wide range of activities, including the implementation of hardware and software solutions, as well as policies and procedures designed to safeguard information. Key components of security include:

1. **Authentication** – Verifying the identity of users or devices before granting access to systems and data.
2. **Authorization** – Determining what actions an authenticated user can perform based on their permissions.
3. **Encryption** – Transforming data into a coded format to prevent unauthorized access during transmission or storage.
4. **Integrity** – Ensuring that data remains accurate and unaltered during its lifetime.
5. **Confidentiality** – Protecting sensitive information from being disclosed to unauthorized individuals.

Security also involves risk management, assessing vulnerabilities, and responding to incidents to maintain the confidentiality, integrity, and availability of information systems. As cyber threats evolve, the field of security continues to advance, incorporating new technologies and strategies to mitigate risks.
