Description: Defense against botnets refers to the strategies and technologies implemented to protect systems and networks from coordinated attacks that use networks of compromised devices. These devices, which can include computers, servers, and IoT devices, are controlled by an attacker to carry out malicious activities such as sending spam, stealing data, or conducting DDoS attacks. In the context of increasing connectivity and the rise of connected devices, defense against botnets becomes more critical due to the heightened risk of a large number of devices being compromised simultaneously. Zero trust in cloud environments also plays a fundamental role, as it implies that no device or user should be trusted by default, requiring rigorous authentication and authorization to prevent unauthorized access to resources. Defenses can include network segmentation, continuous traffic monitoring, the implementation of advanced firewalls, and the use of artificial intelligence to detect anomalous behaviors. In summary, defense against botnets is an essential component of modern cybersecurity, especially in an increasingly interconnected world.
