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

 2.What are the benefits of AWS Security? 

Answer: 

  • It helps you to keep your data safe and protects your privacy. 
  • It makes sure that company compliance is meeting to have a fine-grained access control on your environment. 
  • You can save a lot of money with AWS security while making sure the AWS environment is secure. 
  • Your AWS Cloud infrastructure can be adjusted to meet your growing needs. Whether you are starting out small or expanding rapidly, the AWS Cloud will always be able to accommodate your security needs. 

3.What is Amazon CloudWatch logs? 

Answer: 

Amazon CloudWatch is a monitoring service for AWS cloud resources and the applications you run on Amazon Elastic Compute Cloud (Amazon EC2), Amazon Simple Storage Service (Amazon S3), and other services. CloudWatch collects and provides detailed metrics for Amazon EC2 instances, Amazon EBS volumes, AWS Lambda functions, etc.  

Logs can be created in three different ways: 

  1. They can be initiated by user action 
  2. They can occur automatically as a result of some activity  
  3. They can be programmatically generated at fixed intervals.  

These logs are stored by default in an Amazon S3 bucket and are delivered to you via email, but this process is configurable according to your needs. 

4.What are AWS Trusted Advisor? 

Answer: 

AWS Trusted Advisor is a cloud-based service that performs ongoing assessments of your Amazon Web Services (AWS) resources. The service helps you improve the security, performance, and cost effectiveness of your AWS environments by using industry best practices. It provides advice on various topics, such as data backup and recovery, access control, network security, performance optimization, cost savings opportunities, storage optimization options and more. 

5.What is AWS Identity and Access Management (IAM)? 

Answer: 

IAM is a service that manages users, groups, roles, and permissions for your Amazon Web Services (AWS) resources. IAM enables you to control access to AWS resources in a fine-grained manner. For example, you can give some users permission to read an object while giving other users permission only to change the object’s tags. And with just one click of the mouse, it can take care of assigning appropriate permissions across all of your AWS resources for anyone new or temporary who needs access.

6.How can you keep your data safe while transferring it to the cloud? 

Answer: 

All data in transit from your cloud-based applications must be encrypted. And while you can use CloudHSM or KMS to encrypt data at rest, encrypting in transit requires a different approach. There are three types of encryption methods used for data protection: SSL (HTTPS), SSH, and IPsec. 

7.What is an AWS cloudtrail? 

Answer: 

CloudTrail is a service that records AWS API calls for your account and delivers log files to you. The recorded information includes the identity of the user, their IP address, which region they used, what time of day they made a request, what resource they accessed, and so on. CloudTrail provides a way of monitoring your AWS infrastructure for misconfigurations or abuse. It does not provide any control over or auditing of your use of resources. 

8.What is an AWS AWS Config? 

Answer: 

An AWS Config is a monitoring service that helps you monitor your Amazon Web Services (AWS) resources. It gathers configuration data of EC2 instances, RDS instances, Route 53 hosted zones, CloudFront distributions, Elastic Load Balancers (ELBs), Auto Scaling groups (ASGs), Storage volumes, etc. Once gathered, it stores it securely in Amazon S3 buckets in a JSON format. Also you can use it as an auditing tool by comparing snapshots over time. 

9.What is a DDoS attack, and what services in AWS can minimize them? 

Answer: 

A distributed denial-of-service (DDoS) attack is an attempt to make a computer resource unavailable by overwhelming it with traffic from multiple sources. It can also refer more generally to a denial-of-service attack against any service that relies on web traffic.  

The basic idea is simple: compromise tens or hundreds of thousands of machines across multiple networks and have them request something from your target at exactly the same time.  

The best way to guard against them is Cloud services. Because they’re capable of scaling up or down depending on usage, they can fend off DDoS attacks far more effectively than on-premise systems ever could. 

Tools you can use to minimize DDoS: 

  • AWS Shield 
  • AWS WAF 
  • Amazon Route53 
  • Amazon CloudFront 
  • ELB 
  • VPC 

10.What is the difference between CloudWatch and CloudTrail? 

Answer: 

CloudWatch is a monitoring service that collects metrics such as Amazon EC2 CPU utilization, memory availability, etc. It also collects events like a new instance launch or an instance terminating.  

CloudTrail logs API calls made on your account by users and administrators along with parameters, request IDs, and other information related to these calls. CloudTrail helps you to know who made changes in your account or executed commands using CloudWatch. 

11.Tell me about AWS Security Bulletins? 

Answer: 

Security bulletins from Amazon Web Services (AWS) inform users of potential security issues. Some announcements contain information about specific changes or updates, while others simply state that a particular product is vulnerable but no changes are necessary at present. Many of these announcements can cause alarm among AWS users who aren’t sure what action they should take, but it’s important to know what you should be doing in response. 

12.Explain Amazon Guardduty. 

Answer: 

Amazon GuardDuty is a continuous security monitoring service that helps you detect threats on your AWS infrastructure by collecting and analyzing event data, such as log files, DNS traffic, and IP addresses. With Amazon GuardDuty, you can set up rules in seconds to continuously monitor for activity like port scans or unusual system configuration changes.  

These alerts are sent to an email address of your choice and are tagged with the name of the rule so it’s easy to know what triggered the alert. If there’s an issue detected, you’ll be notified immediately so you can take action. 

13.Name some AWS security monitoring and logging evaluation tools? 

Answer: 

  1. GuardDuty 
  2. CloudWatch 
  3. Macie 
  4. AWS Inspector 

14.What are the native AWS security logging capabilities? 

Answer: 

As of early 2018, Amazon Web Services (AWS) provides several logging options for customers. This includes: 

  • CloudTrail, which tracks user actions on AWS resources. 
  • Amazon Inspector, which helps detect security issues by auditing EC2 instances 
  • GuardDuty, a continuous security monitoring service that analyzes data from CloudTrail,,VPC flow logs, or IoT device logs. 
  • Shield, an identity access management tool. Customers can also use third-party tools like Splunk or Sumo Logic to collect log data. 

15.What is AWS Single Sign-On? 

Answer: 

Single Sign-On (SSO) is a way of using multiple applications without having to enter login credentials. Instead, users log in once by using their credentials on an Identity Provider (IdP), which could be Google, Facebook, or another third-party service.  

Single Sign-On then allows access for other apps that support it. SSO makes it easier for both developers and users since you don’t have to go through as many hoops. It also reduces risk by requiring only one password – yours!
