With increasing capacity and a wide variety of cloud services, Amazon Web Services has become the most popular choice for many businesses and organizations, helping businesses provide scale and cost-effective storage to cloud computing.
AWS security is based on a shared responsibility model: Amazon provides the infrastructure and security, and users are responsible for maintaining the security of the applications in which they run. This model allows users to gain more control over their data traffic, encouraging users to be more cautious. However, before proceeding with the application migration process, it is a good idea to take a look at the following tips to help users get the most out of AWS security.
Understanding the concept of security team
Amazon provides a virtual firewall function to filter it movement running through your cloud segment. However, the AWS firewall is managed in a slightly different way than a traditional firewall. The central element of the AWS firewall is the "security group", which is basically equivalent to what other firewall vendors call the policy, i.e. the rule set. However, there are key differences between security groups and traditional firewall policies, and this should be fully understood.
First, there are no "actions" in the AWS rules that traffic is allowed or abandoned. This is due to the fact that all the rules of AWS are positive and always allow the passage of the specified traffic, in contrast to the traditional rules of the firewall.
Second, AWS rules allow you to specify a traffic source or destination address where the two rules are different. For incoming rules, the source address indicates where the traffic is coming from, but does not require the destination address to say where it is coming from. The output rule is the opposite: you can specify the destination address instead of the source address. The reason for this is that the AWS security team will always automatically set the unspecified fee (source or destination, depending on the situation) for the presence of the application.
AWS gives you great flexibility in enforcing rules. A security team can be applied in many cases, just as you can apply a traditional security policy to many firewalls. AWS also lets you reverse it: Applying multiple security groups to the same presence means that the presence inherits rules from all relevant security groups. This is one of the many features that Amazon offers, allowing you to create security teams for specific functions or operating systems and then combine them to suit your business needs.
Outbound traffic management
Of course, AWS will manage outbound traffic, but management is somewhat different from the usual approach, so be careful. During the initial setup process, AWS users are not automatically directed to the outbound traffic settings. By default, all outgoing traffic is allowed.
Obviously, this is an unsafe setting that can lead to company data loss, so it is recommended to create rules that will only allow you to specify outbound traffic to protect really critical data. Because the AWS Setup Wizard does not automatically start for outgoing settings, you must create and apply these rules manually.
Control and compliance
Once you start using AWS in your products, you need to remember that these applications are now in the light of compliance and internal audit. Amazon offers some built-in features to help with compliance and auditing such as: Amazon CloudWatch, similar to logging servers, and Amazon CloudTrail, which logs and audits your API calls. However, if you are using a hybrid environment centredata, you will need additional compliance and auditing tools.
Your business will be subject to different regulations depending on the industry in which you are located and the type of data you are dealing with. For example, if you deal with credit card information, they are subject to the Payment Card Industry (PCI) regulation. Therefore, if you want to process this sensitive data with the AWS cloud platform, you need the right third-party security management product to have the same reporting capabilities as a normal firewall.
The most important things you need to get from a third party solution is the visibility of all security teams and the entire hybrid asset, as well as the comprehensive security and environment analysis and control that your local security infrastructure can provide.
The security of all those placed in the AWS environment is your responsibility. By considering all of the above, you will be able to protect your data and comply with the requirements while using AWS.
