In cybersecurity:
* Vertical movement: This refers to attackers gaining access to higher privilege levels within a system or network, rather than spreading horizontally.
* Containment: This refers to preventing attackers from moving further within a network, effectively stopping lateral movement.
* Segmentation: This involves breaking down a network into smaller, isolated segments, making it harder for attackers to move laterally.
In other contexts:
* Rectilinear movement: This refers to movement in a straight line, as opposed to lateral movement which involves moving sideways.
* Forward movement: This could be the opposite of lateral movement if the context involves something moving in a specific direction, like a car.
To determine the most accurate opposite, you need to provide more context about the situation you're considering.
