TCP and UDP connections with the process ID and the name that is listening on each port, which

of risk management. The ALE will help the company understand the potential losses associated with
the server failure per year, which can then be weighed against the cost of mitigating the risk (e.g.,
replacing the server or implementing redundancies). This analysis will inform the decision on the
best course of action to manage the risk associated with the aging server.
