Lub Network ACLs (NACLs) yog qhov xaiv tau txheej kev ruaj ntseg rau cov VPC uas ua raws li lub firewall rau kev tswj cov tsheb khiav hauv thiab tawm ntawm ib lossis ntau dua subnets . Default ACL tso cai rau tag nrho cov tsheb khiav hauv thiab sab nraud.

Ib yam li ntawd, tib neeg nug, VPC Security Group yog dab tsi?

AWS pawg ruaj ntseg thiab piv txwv kev ruaj ntseg Txhua pab pawg neeg ruaj ntseg - ua hauj lwm ntau tib yam li firewall - muaj cov txheej txheem uas lim cov tsheb khiav mus rau hauv thiab tawm ntawm EC2 piv txwv. Tsis zoo li cov npe tswj kev nkag mus rau hauv network (NACLs), tsis muaj "tsis lees paub" cov cai. Pawg kev ruaj ntseg yog tshwj xeeb rau a VPC.

Tsis tas li ntawd, qhov txawv ntawm pawg kev ruaj ntseg thiab network ACL yog dab tsi? Pawg kev ruaj ntseg hauv a VPC qhia txog kev khiav tsheb mus los ntawm Amazon EC2 piv txwv. Network ACLs ua haujlwm ntawm qib subnet thiab ntsuas kev nkag mus thiab tawm ntawm subnet. Network ACLs tuaj yeem siv los teeb tsa ob qho kev cai tso cai thiab tsis lees paub. Network ACLs tsis lim tsheb nruab nrab piv txwv hauv tib subnet.

Hais txog qhov no, Kuv tau tso cai ntau npaum li cas VPCs hauv txhua cheeb tsam AWS los ntawm lub neej ntawd?

Txawm tias koj ua tau muaj mus txog tsib VPCs hauv ib cheeb tsam , tsuas yog pib VPC uas AWS tsim rau koj tuaj yeem ua tus default VPC . Txhua VPC yog txuam nrog qhov chaw nyob IP uas yog ib feem ntawm a Classless Inter-Domain Routing (CIDR) thaiv qhov twg yuav siv los faib tus IP chaw nyob rau EC2 piv txwv.

Dab tsi ua haujlwm pab kom ruaj ntseg koj cov peev txheej Amazon VPC los ntawm kev muab kev cais tawm ntawm qib subnet?

Amazon VPC muab advanced kev ruaj ntseg nta , zoo li kev ruaj ntseg pab pawg thiab network nkag tswj cov npe, rau pab kom inbound thiab outbound filtering ntawm qhov piv txwv thiab subnet theem . Tsis tas li ntawd, koj tuaj yeem khaws cov ntaub ntawv hauv Amazon S3 thiab txwv kev nkag mus kom nws tsuas yog siv tau los ntawm piv txwv hauv koj VPC.
