The Open Systems Interconnection model is inefficient as each layer must process data from higher layers, add its own processing, and pass to lower layers, with the reverse at the destination host. This wrapping and unwrapping process is inefficient. The document asks to assess the security advantage of this layered approach.

1. The Open Systems Interconnection model is inherently
inefficient. On the source host, each layer must take the work of
higher layers, add some result, and pass the work to lower
layers. On the destination host, each layer must process these
results from lower layers and pass the appropriate information
to upper layers. Surely this wrapping and unwrapping process is
inefficient. Assess the security advantage of this layered
approach.
