ENO Level 1
This form of ENO is a rogue algorithm, program, or process that has no physical presence but is distributed on the global network, often as malicious, embedded, or altered code.
While its distributed nature makes it difficult to destroy per se, a much lower level of disruption is all that is required to cause the ENO to cease functioning. For instance, in the case of the infamous Naples Urban Network ENO, a targeted destruction of a single piece of code caused the ENO to fall apart, as that malicious piece of self-replicating code was easily identified and easily targeted.
These types of ENO are both the most common and the easiest to deal with from a modern data-security sense.
