What is cloud security in AWS?

AWS helps you to improve your ability to meet core security and compliance requirements, such as data locality, protection, and confidentiality with our comprehensive services and features. AWS allows you to automate manual security tasks so you can shift your focus to scaling and innovating your business.
An important aspect of cloud security policy is data protection; the key threats are that of data unavailability and data loss and release of sensitive information. The security policy needs to also consider the malicious behavior by individuals working within the organization.


What are the important security precautions before migration to AWS Cloud?

  • Data integrity
  • Data loss
  • Data storage
  • Business continuity
  • Uptime
  • Compliance with rules and regulations

What are the infrastructure security products on AWS?

AWS facilitates different security capabilities and services for increasing privacy and control over network access. You can find connectivity options for enabling private or dedicated connection from on-premises or office environment. Infrastructure security also involves encryption of all traffic on AWS global and regional networks among AWS secured facilities.

What services can be used to create a centralized logging solution?

The essential services that you can use are Amazon CloudWatch Logs, store them in Amazon S3, and then use Amazon Elastic Search to visualize them. You can use Amazon Kinesis Firehose to move the data from Amazon S3 to Amazon ElasticSearch.

What are the native AWS Security logging capabilities?

  • AWS CloudTrail
  • AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. With CloudTrail, you can log, continuously monitor, and retain account activity related to actions across your AWS infrastructure.
  • AWS Config
  • AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources. Config continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations.

What is AWS Identity and Access Management (IAM)?

AWS Identity and Access Management (IAM) enables you to manage access to AWS services and resources securely. Using IAM, you can create and manage AWS users and groups, and use permissions to allow and deny their access to AWS resources. IAM is a feature of your AWS account offered at no additional charge.
IAM roles allow you to delegate access with defined permissions to trusted entities without having to share long-term access keys. You can use IAM roles to delegate access to IAM users managed within your account, to IAM users under a different AWS account, or to an AWS service such as EC2.

What is a DDoS attack, and what services can minimize them?

DDoS stands for Distributed Denial of Service. It is a form of cyber attack that targets critical systems to disrupt network service or connectivity that causes a denial of service for users of the targeted resource.
The native tools that can help you deny the DDoS attacks on your AWS services are:
  • AWS Shield
  • AWS WAF
  • Amazon Route53
  • Amazon CloudFront
  • ELB
  • VPC

What is AWS Directory Service?

AWS Directory Service provides multiple directory choices for customers who want to use existing Microsoft AD or Lightweight Directory Access Protocol (LDAP)-aware applications in the cloud. It also offers those same choices to developers who need a directory to manage users, groups, devices, and access. It enables you to join Amazon EC2 instances to your domain easily and supports many AWS and third-party applications and services. It also can support most of the common use cases of small and midsize businesses.

What is the role of AWS Security Bulletins?

Security Bulletins notify customers about one or more vulnerabilities. Customers are responsible for assessing the impact of any actual or potential security vulnerability in the context of their environment.
No matter how carefully engineered the services are, from time to time it may be necessary to notify customers of security and privacy events with AWS services. We will publish security bulletins below. You can also subscribe to our Security Bulletin RSS Feed to keep abreast of security announcements.


Explain how the buffer is used in Amazon web services?

The buffer is used to make the system more robust to manage traffic or load by synchronizing different component. Usually, components receive and process the requests in an unbalanced way. With the help of buffer, the components will be balanced and will work at the same speed to provide faster services.
