An HTTP Web Server hosted on an Oracle Cloud Infrastructure (OCI) compute instance in a public subnet of the VCN1 Virtual Cloud Network has a: * Stateless security ingress rule for port 80 access through Internet Gateway * Stateful Network Security Group notification for port 80 How will the OCI VCN handle request/response traffic to the compute instance for a web page from the HTTP server with port 80? (Choose the best Answer.)
Challenge 4 - Task 1 of 6
Configure Web Application Firewall to Protect Web Server Against XSS Attack
Scenario
You have to protect web applications hosted on OCI from cross-site scripting (XSS) attacks. You can use the OCI Web Application Firewall (WAF) capabilities to create rules that compare against incoming requests to determine if the request contains an XSS attack payload. If a request is determined to be an attack, WAF should return the HTTP Service Unavailable (503) error.
To ensure that the configured WAF blocks the XSS attack, run the following script:[http:// /index.html? ) To complete this deployment, you have to perform the following tasks in the environment provisioned for you: Configure a Virtual Cloud Network (VCN) Create a Compute Instance and install the Web Server Create a Load Balancer and update Security List Create a WAF policy Configure Protection Rules against XSS attacks Verify the created environment against XSS attacks Note:You are provided with access to an OCI Tenancy, an assigned compartment, and OCI credentials. Throughout your exam, ensure to use the assigned Compartment 99233424-C01 and Region us-ashburn-1. Complete the following task in the provisioned OCI environment: Create a VCN using wizard with the name IAD-WAF-PBT-VCN-01 SOLUTION: From the navigation menu, select Networking and then click Virtual Cloud Network. In the left navigation pane, under List Scope, select <your working compartment> from the drop-down menu. Click Start VCN Wizard. Select Create VCN with Internet Connectivity and click Start VCN Wizard. On the Configuration page, enter the following: a)Name: IAD-WAF-PBT-VCN-01 b)Note: Leave all the other options in their default setting. c)Click Next. d)Verify the details on the Review and Create page. Click Create to start creating the VCN and its resources. Click View Virtual Cloud Network to verify the creation of the VCN and its resources. You can now see that the VCN has been successfully created and is in the Available state, with the following components: VCN Public subnet Private subnet Internet gateway NAT gateway Service gateway This format keeps the instructions intact while preserving the original content.
Which IAM policy should be created to give XYZ the ability to list contents of a resource excluding the fneeds to authenticatein prod compartment ? Principle of least priviledge should be used.
You want to make API calls against other OCI services from your instance without configuring user credentials. How would you achieve this?
DYNAMIC GROUP
Dynamic groups allow you to groupOracle Cloud Infrastructureinstances as principalactors, similar to user groups. You can then create policies to permit instances in these groups to make API calls againstOracle Cloud Infrastructureservices. Membership in the group is determined by a set of criteria you define, calledmatching rules.https://docs.cloud.oracle.com/en-us/iaas/Content/Identity/Tasks/callingservicesfrominstances.htm
