Security management: In network management, the set of functions (a) that protects telecommunications networks and systems from unauthorized access by persons, acts, or influences and (b) that includes many subfunctions, such as creating, deleting, and controlling security services and mechanisms; distributing security-relevant information; reporting security-relevant events; controlling the... Performance management may mean: Performance measurement is the process of assessing progress toward achieving predetermined goals, while performance management is building on that process adding the relevant communication and action on the progress achieved against these predetermined goals (Bourne, M.,Franco, M. and Wilkes, J. (2003). ... In computer networking, bandwidth management is the process of measuring and controlling the communications (traffic, packets) on a network link, to avoid filling the link to capacity or overfilling the link, which would result in congestion and poor performance. ... Accounting (Administration) management: Accounting is often referred to as billing management. ...
