Why every AWS administrator should be familiar with security

Security is a major concern for administrators. Security was a key concern for any administrator when on-prem data centres were the center of IT. Sysadmins understood that they had to protect everything, from physical security (e.g. access control, fire prevention and power stability) to maintaining firewalls and antivirus software. The division of responsibilities between what sysadmins should be doing and what belongs to cloud infrastructure owners like Amazon or Microsoft has become a bit more complicated with the introduction of cloud computing into mainstream business computing.
This blog post will discuss why security is so important within Amazon Web Services (AWS), and what every AWS administrator needs to know about cloud security. You have different areas of responsibility depending on whether you are using AWS Platform as a Service, Infrastructure as a Service or Software as a Service offerings.
Why is security important in the cloud?
Because of the amount of information stored in the cloud, security is crucial. Customers’ databases contain a lot of personal information, company intellectual property, as well as proprietary data that is owned by clients or customers. The resulting data breach can cost your company hundreds of millions or even millions of dollars if it is possible to gain access to this information. IBM estimates that a data breach can cause financial losses of $3.86 million on average. This is why security should be a top priority.
You might also need to adhere to specific regulations for your industry or geographic location. The GDPR, which is a European Union regulation, lists specific requirements for personal data collection, storage and transfer. It also includes provisions that address various aspects of cloud computing. HIPAA regulations govern how medical data of patients is stored and accessed by healthcare companies in the United States. AWS administrators have a core responsibility to implement and maintain the right security protocols.

Training is essential. However, it is also important to have access to this information quickly and efficiently. If security were all that mattered, then everything would be so secure that no one could access it. It is essential to use security best practices and allow qualified employees to access data stored in the cloud.
What security does AWS provide?
AWS operates on a shared responsibility model. AWS takes some responsibilities on their own and delegated others to cloud customers/users. Amazon provides security to protect the infrastructure that powers the cloud at a high-level. This includes software, hardware, networking, as well as AWS facilities that host these assets. AWS “operates and manages” the components, from the host operating system and virtualization layer to the physical security of the facilities housing them. AWS also offers a security group firewall. However, it is up to you as an AWS administrator to configure and maintain it.
Amazon does not allow cloud subscribers access to their data centers to verify that security controls are in place. However, the company regularly hires third-party auditors to assess and verify compliance with industry standards and best practices. Visit the Amazon website for more information on compliance.
AWS assumes additional security configuration responsibility if you use managed services. These services include Amazon DynamoDB and Amazon RDS, Amazon Redshift and Amazon EMR. You don’t need to worry about guest operating system and database patching, firewall configuration or disaster recovery. Depe
