Q

To ensure the security of your AWS account, what are two AWS best practices for managing access keys? (choose 2)

– Manage IAM User Access Keys Properly
• Rotating access keys is a recommended practice, but doing it daily would be excessive and hard to manage
• You can use MFA for securing privileged accounts, but it does not secure access keys
• You should use IAM roles where possible, but AWS do not recommend that you don’t create any access keys as they also have a purpose

  • Versioning helps to mitigate the impact of deleting objects as older versions are retained however it does not prevent deletion
  • Encryption protects against unauthorized agents reading your data, it does not protect it from deletion
  • Lifecycle management can also reduce the impact of deleting objects as they may have been archived, but again it does not stop you from deleting them

  4. Group Advisor
A
  1. Access Advisor
  • The IAM console provides information about when IAM users and roles last attempted to access AWS services. This information is calledservice last accessed data. This data can help you identify unnecessary permissions so that you can refine your IAM policies to better adhere to the principle of “least privilege.” That means granting the minimum permissions required to perform a specific task. You can find the data on the Access Advisor tab in the IAM console by examining the detail view for any IAM user, group, role, or managed policy

Q

Which AWS IAM best practice recommends applying the minimum permissions necessary to perform a task when creating IAM policies?

  1. Create individual IAM users
  2. Use roles to delegate permissions
  3. Grant least privilege
  4. Enable MFA for privileged users
A
  1. Grant least privilege

• When you create IAM policies, follow the standard security advice of granting least privilege—that is, granting only the permissions required to perform a task. Determine what users need to do and then craft policies for them that let the users perform only those tasks

45
Q

What are the benefits of using IAM roles for applications that run on EC2 instances? (choose 2)

  1. Easier to configure than using storing access keys within the EC2 instance
  2. More secure than storing access keys within applications
  3. Can apply multiple roles to a single instance
  4. It is easier to manage IAM roles
  5. Role credentials are permanent
A
  1. More secure than storing access keys within applications
  2. It is easier to manage IAM roles
  • Using IAM roles instead of storing credentials within EC2 instances is more secure It is also easier to manage roles
  • It is not easier to configure as there are extra steps that need to be completed
  • You cannot apply multiple roles to a single instance
  • Role credentials are temporary, not permanent, and are rotated automatically
46
Q

A web server is being maliciously targeted, how can a systems administrator deny access from a list of known attacker IP addresses? (choose 2)

  1. Using a local firewall such as iptables
  2. Using a rule on the Internet Gateway
  3. Using a Security Group deny rule
  4. Using a Network ACL deny rule
  5. Through VPC route table configuration
A
  1. Using a local firewall such as iptables
  2. Using a Network ACL deny rule
  • To block access to a known list of IP addresses you can configure a local firewall on the web server or use Network ACL deny rules
  • You cannot create deny rules with Security Groups (only allow rules)
  • Internet Gateways do not have allow/deny rules and route table configuration could not be used to break connections with specific addresses
47
Q

Which of the following is not a best practice for protecting the root user of an AWS account?

  1. Don’t share the root user credentials
  2. Enable MFA
  3. Remove administrative permissions
  4. Lock away the AWS root user access keys
A
  1. Remove administrative permissions

• You cannot remove administrative permissions from the root user of an AWS account. Therefore, you must protect the account through creating a complex password, enabling MFA, locking away access keys (assuming they’re even required), and not sharing the account details

48
Q

What types of rules can be defined in a security group? (choose 2)

  1. Inbound
  2. Deny
  3. Tags
  4. Outbound
  5. Stateful
A
  1. Inbound
  2. Outbound
  • You can create inbound and outbound rules in a security group
  • You can tag a security group but this is not a type of rule
  • You cannot create deny rules with a security group, all rules entries allow traffic
  • A security group is stateful but this is not a rule type
49
Q

Which AWS security tool uses an agent installed in EC2 instances and assesses applications for vulnerabilities and deviations from best practices?

  1. AWS Trusted Advisor
  2. AWS Personal Health Dashboard
  3. AWS TCO Calculator
  4. AWS Inspector
A
  1. AWS Inspector
  • Inspector is an automated security assessment service that helps improve the security and compliance of applications deployed on AWS. Inspector automatically assesses applications for vulnerabilities or deviations from best practices. Uses an agent installed on EC2 instances

  • AWS Personal Health Dashboard provides alerts and remediation guidance when AWS is experiencing events that may impact you
  • The AWS TCO calculator can be used to compare the cost of running your applications in an on-premises or colocation environment to AWS
50
Q

Up to what layer of the OSI model does AWS Web Application Firewall operate?

  1. Layer 3
  2. Layer 4
  3. Layer 5
  4. Layer 7
A
  1. Layer 7
  • The AWS Web Application Firewall operates up to the application layer (layer 7). You can use AWS WAF to create custom rules that block common attack patterns, such as SQL injection or cross-site scripting, and rules that are designed for your specific application
  • https://aws.amazon.com/waf/
51
Q

What do you need to log into the AWS console?

  1. User name and password
  2. Key pair
  3. Access key and secret ID
  4. Certificate
A
  1. User name and password
  • You can log into the AWS console using a user name and password
  • You cannot log in to the AWS console using a key pair, access key & secret ID or certificate
52
Q

Your manager has asked you to explain the benefits of using IAM groups. Which of the below statements are valid benefits? (choose 2)

  1. You can restrict access to the subnets in your VPC
  2. Groups let you specify permissions for multiple users, which can make it easier to manage the permissions for those users
  3. Provide the ability to create custom permission policies
  4. Enables you to attach IAM permission policies to more than one user at a time
  5. Provide the ability to nest groups to create an organizational hierarchy
A
  1. Groups let you specify permissions for multiple users, which can make it easier to manage the permissions for those users
  2. Enables you to attach IAM permission policies to more than one user at a time
  • Groups are collections of users and have policies attached to them
  • A group is not an identity and cannot be identified as a principal in an IAM policy
  • Use groups to assign permissions to users
  • Use the principal of least privilege when assigning permissions
  • You cannot nest groups (groups within groups)
53
Q

Which of the authentication options below can be used to authenticate using AWS APIs? (choose 2)

  1. Key pairs
  2. Access keys
  3. Server passwords
  4. Security groups
  5. Server certificates
A
  1. Access keys
  2. Security groups
  • Key pairs are used for encrypting logon information when accessing EC2 instances
  • Access keys are a combination of an access key ID and a secret access key
  • A server password cannot be used to authenticate with an API
  • Server certificates are SSL/TLS certificates that you can use to authenticate with some AWS services
  • Security groups are an instance-level firewall used for controlling access to AWS resources

Q

When using Identity and Access Management (IAM) what is the process of gaining access to a resource?

  1. First you authenticate, then you are authorized, and then you gain access
  2. First you are authorized, then you authenticate, and then you gain access
  3. First you authenticate, then you gain access, and then you are authorized
  4. With IAM you do not need to authenticate or be authorized
A
  1. First you authenticate, then you are authorized, and then you gain access
  • The process is that you are first authenticated (the system checks you are who you say you are), then you are authorized (the system determined the resources you are allowed to access), and then you are able to access the resources
