Runtime Security refers to the protection of applications while they are running. It involves monitoring and managing the behavior of software to detect and prevent security threats in real-time. This can include identifying unauthorized access, code injection, or other malicious activities that could compromise the system. To achieve effective Runtime Security, various tools and techniques are employed, such as intrusion detection systems and application firewalls. These solutions help ensure that applications operate safely, maintaining the integrity and confidentiality of data while minimizing the risk of attacks during execution.
