They\u200b are components of\u2063 the AWS security barrier, which is designed to keep your data and \u2064resources safe.<\/p>\n<p>Network Access\u200d Control List (ACL) refers to a list\u2063 of rules \u200cthat determines who\u200b or what can access your\u2064 instances and resources in the \u200bcloud.\u2064 These \u200crules are applied to\u200c all instances\u200d you have\u2064 running in the VPC. ACLs allow you to control both inbound and outbound traffic and \u2064create more specific rules by using IP address and port ranges. Here\u200b are \u2063some features of\u200d ACLs:<\/p>\n<ul>\n<li>You can specify what is approved traffic, and what is rejected.<\/li>\n<li>You can also set\u200b up port protection to \u2063define how connections from different ports will\u2062 be\u2064 handled.<\/li>\n<li>It\u200b is possible to \u200boverride existing rules with a more specific rule.<\/li>\n<li>You can \u200cset up aging\u2064 rules that\u200b determine when a rule will expire.<\/li>\n<\/ul>\n<p>Security Groups are also utilized for the purpose of access \u200bcontrol to AWS \u200cresources. They can be\u200b used to configure Network traffic rules, decide\u2063 who has access to your instance, how and when.\u2062 While\u200c ACLs work on a network layer, Security\u200c Groups\u200c work on\u200b an instance layer. \u200bUnlike ACLs, Security Groups offer configurable firewalls that \u2062are used\u200c to control access to your AWS resources.

The two \u200cmain services are\u200d Network ACLs\u2063 (NACL) and Security Groups (SG). Both are essential for securing\u2064 your EC2 \u200cinstances against unauthorized \u2063access.<\/p>\n<ul>\n<li><b>Network ACLs\u200c (NACLs):<\/b> NACLs are stateless firewalls.\u200c This\u200c means that \u200deach rule\u200c you create needs to be specified both ways: inbound traffic\u2063 and\u2064 outbound \u200dtraffic. NACLs\u200c can have up to 50 \u2062rules and \u2063are \u200dassigned\u200b to subnets. All the traffic \u200dleaving \u200cor entering a \u200csubnet must comply with the rules,\u200b or it will be dropped.<\/li>\n<li><b>Security Groups (SGs):<\/b> SGs are stateful firewalls. That means\u200d that you can specify the rule only once, and your traffic \u200cwill\u2062 be allowed in\u2062 both directions. SGs can hold\u2064 up to 50 rules and are assigned to \u200dEC2 instances. This makes them better for protecting your instances from unauthorized\u2063 access.<\/li>\n<\/ul>\n<p>Using NACLs and SGs\u200d together\u200d is the best\u2064 way to maximize your security in\u200b AWS. \u2063NACLs should be \u200dused to control the \u2062access entering and leaving \u2062your VPC, while\u200c SGs should be used to control the access \u2064to specific EC2 \u200binstances.\u200c Both should be configured\u200d to be as restrictive as possible, so that \u2063only necessary traffic can enter or be sent out.
