Homonym: Intrusions (Encroachments)
An intrusion refers to an unwanted or unauthorized entry into a space or system. In the context of cybersecurity, it involves a breach where an attacker gains access to a computer network or system, often with malicious intent. This can lead to data theft, system damage, or other harmful consequences.
In geology, an intrusion describes the process where molten rock, or magma, moves into existing rock formations. When this magma cools and solidifies underground, it forms igneous rocks. These geological intrusions can create valuable mineral deposits and shape the landscape over time.
