The difference between invasion and intrusion

1, invasion and intrusion refer to the entry of one entity into the territory or space of another entity, but the nature is different. Invasion emphasizes an act of aggression, which usually refers to illegal and unauthorized entry into other people's territory, territory or system, and is often used to describe military and cyber attacks. Invasion is more extensive, including legal or illegal entry, which does not necessarily mean invasion. It is often used to describe entering a certain field, territory, system, private space, etc.

2, invasion usually refers to aggressive or destructive behavior, often with the meaning of illegal and hostile, may have a serious impact on the infringed party. Invasion, on the other hand, is relatively neutral, which can refer to legal entry, such as entering other people's rooms and systems, or illegal entry, but it is less serious and does not necessarily cause serious consequences. They are different in nature and degree.
