?– Because end subscribers are typically used to having inherent security provided by
DSL lines, they cannot be expected to become security-aware IT experts overnight
when switching from their legacy-leased copper-based lines to EPON connections;
extra measures must be taken at the link level to assure a smooth transition for
typical ISP customers, without privacy degradation and any security concerns for
private and sensitive data.
?– Huge enterprise LANs, which typically operate in the P2P mode providing inherent
security (additionally supervised by experienced IT staff), can be open suddenly
to all types of system-level security breaches once linked to the WAN level
using insecure EPON connections. It is, therefore, imperative to provide inherent
data privacy, authentication, and payload security; otherwise, business customers
might stick with exiting leased lines.
Additionally, many opponents of link-level security mechanisms indicate that existing
solutions such as secure socket layer (SSL) are more than sufficient to handle
data transaction security, though again certain issues need to be emphasized at
this point:
?– Large servers using the SSL protocol need to handle a dramatically growing amount
of data traffic.
