Definition
Host-based attacks target individual computers or devices, exploiting vulnerabilities within their operating systems, applications, or configurations. These attacks aim to compromise the confidentiality, integrity, or availability of the host system and its data. They often involve malware infection, unauthorized access, or denial-of-service actions directly on the targeted machine. Understanding host-based attacks is crucial for implementing effective endpoint security measures and protecting critical assets. For instance, a ransomware attack encrypting a user's files is a classic example of a host-based attack. Unlike network-based attacks that traverse the network to reach their target, host-based attacks originate or are executed directly on the compromised host. This concept is frequently covered in cybersecurity certifications like CompTIA Security+ and CySA+.
