Some cells have cell walls, and viruses as I understand it have to penetrate that wall.
Nuts and fruit sometimes have protective shells.
An argument could be made that borders and territory are fundamental.
For an agent that seeks to defeat border control mechanisms, it can potentially be effective to convince the target parties that border control mechanisms generally or specifically are harmful, are useless, or have drawbacks. This is not always completely false in all cases, for instance regarding immune systems misidentifying harmless allergens as harmful, causing potentially significant harm as allergy. However, if an agent uses such approaches, they have to be careful not to buy into that idea themselves, lest matters may become strange and weird. And, in the modern day, if an agent is especially successful and competent with defeating border control mechanisms, considering the extreme power that the human species holds these days, such as with nuclear weapons, it puts an extreme responsibility on such successful agents, at least in the current systems. Otherwise, the consequences might be extremely detrimental to the human species as a whole.
What an interesting set of increasingly bad metaphors.
IT defenses are just an existing human cognitive bias carried forward into a new realm… a bad idea carried forward is still a bad idea.
The cell wall of the vascular plants doesn’t exist to keep viruses (or anything) out, it exists to provide structural rigidity and keep water pressure in… in fact any plant without a sufficiently permeable cell wall dies as a consequence.
The virus in turn isn’t an agent at all, it just passively exploits the permeability of cell walls and membranes in order to replicate. In doing so it helps drive the cell’s evolution, by both acting as a pressure and a mutagen. Life, again, depends on information transfer across permeable membranes.
Nuts and other fruits, by the way, are the sexual apparatus of the plant… they don’t even begin to develop until a migration has occurred, and once they’ve developed their primary purpose is, again, to keep energy and water in more than they’re to keep anything out… in fact they universally fail to function if they’re too good at keeping the outside out.
