1.OverviewofNetworkSecurity

Networksecurityreferstothemeasurestakentoprotectcomputernetworksandthedatatransmittedthroughthemfromunauthorizedaccess,misuse,ormodification.Itinvolvesvarioustechniquesandprotocolsthatworktogethertoensuretheconfidentiality,integrity,andavlabilityofnetworkresources.

2.Firewalls

Firewallsareessentialcomponentsofnetworksecurityinfrastructure.Theyactasabarrierbetweeninternalandexternalnetworks,filteringandmonitoringincomingandoutgoingnetworktraffic.Firewallscanbeimplementedeitherinhardwareorsoftwareform.Theyexaminepacketsandenforceaccesscontrolpoliciesbasedonpredefinedrules,preventingunauthorizedaccessandprotectingagnstnetworkthreats.

Thereareseveraltypesoffirewalls,including:

PacketFilteringFirewalls:Thesefirewallsanalyzeindividualpacketsbasedonpredeterminedrules.TheyalloworblockpacketsbasedoncriteriasuchassourceanddestinationIPaddresses,portnumbers,andprotocol.

StatefulInspectionFirewalls:Thesefirewallskeeptrackofthestateofnetworkconnectionsandinspectpacketcontents,ensuringthatonlyvalidpacketsareallowed.

ApplicationProxyFirewalls:Thesefirewallsactasintermediariesbetweenclientsandservers.Theyfilterpacketsattheapplicationlayer,providinganadditionallayerofsecuritybyexaminingandvalidatingapplication-leveldata.

3.IntrusionDetectionandPreventionSystems(IDPS)

HybridIDPS:Thesesystemscombinebothnetwork-basedandhost-basedIDPSforcomprehensivenetworksecuritymonitoring.

4.VirtualPrivateNetworks(VPNs)
