Description: Open system security refers to a set of measures and protocols designed to protect the integrity, confidentiality, and availability of data in systems that allow interoperability and information exchange. These open systems, which can include software, hardware, and networks, are fundamental in an increasingly interconnected technological environment. Security in these systems involves implementing practices such as authentication, data encryption, access management, and activity monitoring. Unlike closed systems, where control and security may be easier to manage, open systems present unique challenges due to their accessible and collaborative nature. Therefore, it is crucial to adopt a proactive approach in identifying vulnerabilities and applying security solutions that not only protect data but also maintain the functionality and interoperability that characterize these systems. Open system security is essential for fostering trust between users and organizations, ensuring that information is handled securely and efficiently in a constantly evolving digital landscape.
