Configuration- involves initializing the network, enrolling new members, controlling
thetopology, keeping equipment inventories, etc
Performance monitoring- involves monitoring throughputs, delays, detecting packet
andframe errors, etc for all layers of communication
Fault isolation- involves detection of faulty conditions on the network, tracing of errorsources,
and general text and maintenance aids.
Accounting- involves keeping a record of the usage of network resources for billing
purposese.g. recording the usage of a shared printer by each department for the purposes of
billing, recording the total time spent on a dial-up connection by each department for the
purposes of billing, etc
Security- involves access control, encryption and authentication, reporting of break-in
attemptsand success.
Security implications of remote network management:
1.Unauthorized access would have to be detected immediately and the terminal involved
identified to so as to effectively control unauthorized access.
2.Data at every node would have to be secured from un-authorized modification or deletion
so as to prevent destruction of data at any node in the network.
3.The security function of network management would have to be centralized on a terminal
so as to simplify the administration of security.
4.All data in transit would have to be secured remotely to prevent eaves dropping.
5.A log of all accesses to the network must be maintained to enable the network manger
identify instances of successful unauthorized access and employ the relevant preventive
mechanisms.
Security mechanisms needed for remote network management:
1.Username and password systems- to prevent unauthorized access
2.Use of audit trails. The audit trails could be maintained by the network operatingsoftware.
Audit trails enable instances of unauthorized access to be identified thus enabling
preventive mechanisms to be put in place to stem unauthorized access in future.
3.Data encryption to prevent unauthorized access.
4.Record and file locking to prevent simultaneous update of files thus maintaining
integrityof transactions.
5.Use of firewalls to prevent protect the network from external threats e.g. hackers
(ii) Challenges facing the convergence of networks in business organizations:
1.Incompatibility of different organizational networks
Organizational networks may be incompatible because of the hardware in the networks or the
protocols in the networks and this may prevent the convergence of networks.
2. Security concerns
Organizations may be reluctant to converge their networks because converging the networks
would expose individual organizational networks to more security threats e.g. hackers who may
corrupt organizational data
3. Competition amongst business organizations
Fierce business competitors may be reluctant to converge their networks because convergence
would imply sharing of data in the network which may be perceived as a threat to the
competitive advantage of an organization with respect to its competitors.
4. Cost concerns
Convergence of networks would imply interconnection costs which vary according to the
medium used to interconnect the networks. For instance, a satellite link to the nodes in the
network would be very expensive as compared to a phone line link.
5. Lack of uniformity in legislation across many countries
Most countries in Africa lack well-defined data protection laws and computer crime laws in
contrast to European nations that have well defined laws put in place (e.g. The Data protection
act of England). It‘s clear that convergence of networks across such states may bring about
problems since what may pass as law in one country may not pass as law in another country.
Perpetrators of computer crime may take advantage of this opportunity.
