1. I have a private WAN that are (not connected to Internet) using MPLS to connect a few separate geographical location LAN. HQ LAN communicate with all sisters company LAN, but other LAN has its own autonomy and separately controls.
What are the risks and threats that this network face? Can external intruder connect to MPLS network via the MPLS service provider network?
2. Same as above, but now the private WAN is using point to point leased line (E1 & E3) network to connect these LAN.
What are the risks and threats that this leased line network face? Can external intruder connect to this leased line network via the leased line service provider network?
