The first level of cloud protection is provided by security groups. This is the most fundamental aspect of centralized public cloud security management. The security group manages the rules that allow traffic. Contrary to traditional firewalls, who control traffic based on the rules of permission and denial, security groups only accept the rules and should not rule out the rules. There are no rules to restrict movement; The absence of permit rule works as a rebate.
Cloud security groups are really reminiscent of the firewalls we had in the 90s. In those days, host-based firewalls were located on the server itself, and if you cracked the server, you also got access to the firewall’s security settings. Similarly, the first level of cloud security is directly related to the server (for example, in the context of cloud architecture). In the case of older firewalls, after entering an instance, the management of the associated security group (s) becomes available, posing a significant risk that could endanger the security status of the cloud. In this way, enterprises use more stringent cloud-based network security management tools.
