Attack¶
An attack on a server is any deliberate attempt to exploit, disrupt, or gain unauthorized access to a server, its data, or its services. These attacks can target vulnerabilities in software, hardware, or human behavior, and are typically carried out by malicious actors for various motives, such as stealing data, causing downtime, or using the server as a launchpad for further attacks.
Attack relies on existing vulnerabilities. They may also exploit published or unpublished 0-day vulnerabilities, or target specific weakness.
Attack may be automated in various manner, from brute force campaign targetting the same vulnerability on large number of server to tailored attack on a server.
Attack may be blocked by appropriate counter measures, such as access blocking, bug fixing, configuration application, server moving, etc.
