1.1Ensure service level admins are created to manage resources of particular service1
Attributes
- Profile
Level 1
- Section
- Identity and Access Management
- Description
To apply least-privilege security principle, one can create service-level administrators in corresponding groups and assigning specific users to each service-level administrative group in a tenancy. This limits administrative access in a tenancy.
It means service-level administrators can only manage resources of a specific service.
Example policies for global/tenant level service-administrators
Allow group VolumeAdmins to manage volume-family in tenancy Allow group ComputeAdmins to manage instance-family in tenancy Allow group NetworkAdmins to manage virtual-network-family in tenancyA tenancy with identity domains : An Identity Domain is a container of users, groups, Apps and other security configurations. A tenancy that has Identity Domains available comes seeded with a 'Default' identity domain. If a group belongs to a domain different than the default domain, use a domain prefix in the policy statements. Example - Allow group <identity_domain_name>/<group_name> to <verb> <resource-type> in compartment <compartment_name> If you do not include the <identity_domain_name> before the <group_name>, then the policy statement is evaluated as though the group belongs to the default identity domain.Organizations have various ways of defining service-administrators. Some may prefer creating service administrators at a tenant level and some per department or per project or even per application environment ( dev/test/production etc.). Either approach works so long as the policies are written to limit access given to the service-administrators.
Example policies for compartment level service-administrators
Allow group NonProdComputeAdmins to manage instance-family in compartment dev Allow group ProdComputeAdmins to manage instance-family in compartment production Allow group A-Admins to manage instance-family in compartment Project-A Allow group A-Admins to manage volume-family in compartment Project-AA tenancy with identity domains : An Identity Domain is a container of users, groups, Apps and other security configurations. A tenancy that has Identity Domains available comes seeded with a 'Default' identity domain. If a group belongs to a domain different than the default domain, use a domain prefix in the policy statements. Example - Allow group <identity_domain_name>/<group_name> to <verb> <resource-type> in compartment <compartment_name> If you do not include the <identity_domain_name> before the <group_name>, then the policy statement is evaluated as though the group belongs to the default identity domain.- Audit Procedure
From CLI:
-
Set up OCI CLI with an IAM administrator user who has read access to IAM resources such as groups and policies.
-
Run OCI CLI command providing the root_compartment_OCID Get the list of groups in a tenancy
oci iam group list --compartment-id <root_compartment_OCID> | grep nameA tenancy with identity domains : The above CLI commands work with the default identity domain only. For IaaS resource management, users and groups created in the default domain are sufficient.-
Ensure distinct administrative groups are created as per your organization's definition of service-administrators.
-
Verify the appropriate policies are created for the service-administrators groups to have the right access to the corresponding services. Retrieve the policy statements scoped at the tenancy level and/or per compartment.
oci iam policy list --compartment-id <root_compartment_OCID> | grep "in tenancy" oci iam policy list --compartment-id <root_compartment_OCID> | grep "in compartment"The --compartment-id parameter can be changed to a child compartment to get policies associated with child compartments.
oci iam policy list --compartment-id <child_compartment_OCID> | grep "in compartment"Verify the results to ensure the right policies are created for service-administrators to have the necessary access.
-
- Assessment Status
Manual
- Rationale Statement
Creating service-level administrators helps in tightly controlling access to Oracle Cloud Infrastructure (OCI) services to implement the least-privileged security principle.
- Remediation Procedure
Refer to the policy syntax document and create new policies if the audit results indicate that the required policies are missing. This can be done via OCI console or OCI CLI/SDK or API.
Creating a new policy:
From CLI:
oci iam policy create [OPTIONS]Creates a new policy in the specified compartment (either the tenancy or another of your compartments). If you're new to policies, see Getting Started with Policies
You must specify a name for the policy, which must be unique across all policies in your tenancy and cannot be changed.
You must also specify a description for the policy (although it can be an empty string). It does not have to be unique, and you can change it anytime with UpdatePolicy.
You must specify one or more policy statements in the statements array. For information about writing policies, see How Policies Work and Common Policies.
1.2Ensure permissions on all resources are given only to the tenancy administrator group1
Attributes
- Profile
Level 1
- Section
- Identity and Access Management
- Description
There is a built-in OCI IAM policy enabling the Administrators group to perform any action within a tenancy. In the OCI IAM console, this policy reads:
Allow group Administrators to manage all-resources in tenancyAdministrators create more users, groups, and policies to provide appropriate access to other groups.
Administrators should not allow any-other-group full access to the tenancy by writing a policy like this -
Allow group any-other-group to manage all-resources in tenancyThe access should be narrowed down to ensure the least-privileged principle is applied.
- Audit Procedure
From CLI:
- Run OCI CLI command providing the root compartment OCID to get the list of groups having access to manage all resources in your tenancy.
oci iam policy list --compartment-id <root_compartment_OCID> | grep -i "to manage all-resources in tenancy"- Verify the results to ensure only the
Administratorsgroup has access to manage all resources in tenancy.
"Allow group Administrators to manage all-resources in tenancy"
- Assessment Status
Automated
- Rationale Statement
Permission to manage all resources in a tenancy should be limited to a small number of users in the
Administratorsgroup for break-glass situations and to set up users/groups/policies when a tenancy is created.No group other than
Administratorsin a tenancy should need access to all resources in a tenancy, as this violates the enforcement of the least privilege principle.- Remediation Procedure
From Console:
- Login to OCI console.
- Go to
Identity->Policies, In the compartment dropdown, choose the root compartment. Open each policy to view the policy statements. - Remove any policy statement that allows any group other than
Administratorsor any service access to manage all resources in the tenancy.
From CLI:
The policies can also be updated via OCI CLI, SDK and API, with an example of the CLI commands below:
-
Delete a policy via the CLI:
oci iam policy delete --policy-id <policy-ocid> -
Update a policy via the CLI:
oci iam policy update --policy-id <policy-ocid> --statements <json-array-of-statements>
Note: You should generally not delete the policy that allows the
Administratorsgroup the ability to manage all resources in the tenancy.
1.3Ensure IAM administrators cannot update tenancy Administrators group1
Attributes
- Profile
Level 1
- Section
- Identity and Access Management
- Description
Tenancy administrators can create more users, groups, and policies to provide other service administrators access to OCI resources.
For example, an IAM administrator will need to have access to manage resources like compartments, users, groups, dynamic-groups, policies, identity-providers, tenancy tag-namespaces, tag-definitions in the tenancy.
The policy that gives IAM-Administrators or any other group full access to 'groups' resources should not allow access to the tenancy 'Administrators' group.
The policy statements would look like -
Allow group IAMAdmins to inspect users in tenancy Allow group IAMAdmins to use users in tenancy where target.group.name != 'Administrators' Allow group IAMAdmins to inspect groups in tenancy Allow group IAMAdmins to use groups in tenancy where target.group.name != 'Administrators'Note: You must include separate statements for 'inspect' access, because the target.group.name variable is not used by the ListUsers and ListGroups operations
- Audit Procedure
From CLI:
- Run the following OCI CLI commands providing the root_compartment_OCID
oci iam policy list --compartment-id <root_compartment_OCID> | grep -i " to use users in tenancy" oci iam policy list --compartment-id <root_compartment_OCID> | grep -i " to use groups in tenancy"- Verify the results to ensure that the policy statements that grant access to use or manage users or groups in the tenancy have a condition that excludes access to
Administratorsgroup or to users in the Administrators group.
- Assessment Status
Automated
- Rationale Statement
These policy statements ensure that no other group can manage tenancy administrator users or the membership to the 'Administrators' group thereby gain or remove tenancy administrator access.
- Remediation Procedure
From Console:
- Login to OCI Console.
- Select
Identityfrom Services Menu. - Select
Policiesfrom Identity Menu. - Click on an individual policy under the Name heading.
- Ensure Policy statements look like this -
Allow group IAMAdmins to use users in tenancy where target.group.name != 'Administrators' Allow group IAMAdmins to use groups in tenancy where target.group.name != 'Administrators'

Automated
- Rationale Statement
In keeping with the overall goal of having users create a password that is not overly weak, an eight-character minimum password length is recommended for an MFA account, and 14 characters for a password only account. In addition, maximum password length should be made as long as possible based on system/software capabilities and not restricted by policy.
In general, it is true that longer passwords are better (harder to crack), but it is also true that forced password length requirements can cause user behavior that is predictable and undesirable. For example, requiring users to have a minimum 16-character password may cause them to choose repeating patterns like fourfourfourfour or passwordpassword that meet the requirement but aren’t hard to guess. Additionally, length requirements increase the chances that users will adopt other insecure practices, like writing them down, re-using them or storing them unencrypted in their documents.
Password composition requirements are a poor defense against guessing attacks. Forcing users to choose some combination of upper-case, lower-case, numbers, and special characters has a negative impact. It places an extra burden on users and many will use predictable patterns (for example, a capital letter in the first position, followed by lowercase letters, then one or two numbers, and a “special character” at the end). Attackers know this, so dictionary attacks will often contain these common patterns and use the most common substitutions like, $ for s, @ for a, 1 for l, 0 for o.
Passwords that are too complex in nature make it harder for users to remember, leading to bad practices. In addition, composition requirements provide no defense against common attack types such as social engineering or insecure storage of passwords.

1.5Ensure IAM password policy expires passwords within 365 days1
Attributes
- Profile
Level 1
- Section
- Identity and Access Management
- Description
IAM password policies can require passwords to be rotated or expired after a given number of days. It is recommended that the password policy expire passwords after 365 and are changed immediately based on events.
- Audit Procedure
- Go to Identity Domains: https://cloud.oracle.com/identity/domains/
- Select the
Compartmentyour Domain to review is in - Click on the Domain to review
- Click on
Settings - Click on
Password policy - Click each Password policy in the domain
- Ensure
Expires after (days)is less than or equal to 365 days
- Assessment Status
Manual
- Rationale Statement
Excessive password expiration requirements do more harm than good, because these requirements make users select predictable passwords, composed of sequential words and numbers that are closely related to each other.10 In these cases, the next password can be predicted based on the previous one (incrementing a number used in the password for example). Also, password expiration requirements offer no containment benefits because attackers will often use credentials as soon as they compromise them. Instead, immediate password changes should be based on key events including, but not limited to:
- Indication of compromise
- Change of user roles
- When a user leaves the organization.
Not only does changing passwords every few weeks or months frustrate the user, it’s been suggested that it does more harm than good, because it could lead to bad practices by the user such as adding a character to the end of their existing password.
In addition, we also recommend a yearly password change. This is primarily because for all their good intentions users will share credentials across accounts. Therefore, even if a breach is publicly identified, the user may not see this notification, or forget they have an account on that site. This could leave a shared credential vulnerable indefinitely. Having an organizational policy of a 1-year (annual) password expiration is a reasonable compromise to mitigate this with minimal user burden.

1.7Ensure MFA is enabled for all users with a console password1
Attributes
- Profile
Level 1
- Section
- Identity and Access Management
- Description
Multi-factor authentication is a method of authentication that requires the use of more than one factor to verify a user’s identity.
With MFA enabled in the IAM service, when a user signs in to Oracle Cloud Infrastructure, they are prompted for their user name and password, which is the first factor (something that they know). The user is then prompted to provide a verification code from a registered MFA device, which is the second factor (something that they have). The two factors work together, requiring an extra layer of security to verify the user’s identity and complete the sign-in process.
OCI IAM supports two-factor authentication using a password (first factor) and a device that can generate a time-based one-time password (TOTP) (second factor).
See OCI documentation for more details.

- Assessment Status
Automated
- Rationale Statement
Multi factor authentication adds an extra layer of security during the login process and makes it harder for unauthorized users to gain access to OCI resources.
- Remediation Procedure
Each user must enable MFA for themselves using a device they will have access to every time they sign in. An administrator cannot enable MFA for another user but can enforce MFA by identifying the list of non-complaint users, notifying them or disabling access by resetting the password for non-complaint accounts.

1.14Ensure Instance Principal authentication is used for OCI instances, OCI Cloud Databases and OCI Functions to access OCI resources1
Attributes
- Profile
Level 1
- Section
- Identity and Access Management
- Description
OCI instances, OCI database and OCI functions can access other OCI resources either via an OCI API key associated to a user or via Instance Principal. Instance Principal authentication can be achieved by inclusion in a Dynamic Group that has an IAM policy granting it the required access or using an OCI IAM policy that has
request.principaladded to thewhereclause. Access to OCI Resources refers to making API calls to another OCI resource like Object Storage, OCI Vaults, etc.- Audit Procedure
From Console (Dynamic Groups):
- Go to https://cloud.oracle.com/identity/domains/
- Select a Compartment
- Click on a Domain
- Click on
Dynamic groups - Click on the Dynamic Group
- Check if the Matching Rules includes the instances accessing your OCI resources.
From Console (request.principal):
- Go to https://cloud.oracle.com/identity/policies
- Select a Compartment
- Click on an individual policy under the Name heading.
- Ensure Policy statements look like this :
allow any-user to <verb> <resource> in compartment <compartment-name> where ALL {request.principal.type='<resource_type>', request.principal.id='<resource_ocid>'}or
allow any-user to <verb> <resource> in compartment <compartment-name> where ALL {request.principal.type='<resource_type>', request.principal.compartment.id='<compartment_OCID>'}From CLI (request.principal):
- Execute the following for each compartment_OCID:
oci iam policy list --compartment-id <compartment_OCID> | grep request.principal- Ensure that the condition includes the instances accessing your OCI resources
- Impact Statement
For an OCI instance that contains embedded credential audit the scripts and environment variables to ensure that none of them contain OCI API Keys or credentials.
- Assessment Status
Manual
- Rationale Statement
Instance Principal reduces the risks related to hard-coded credentials. Hard-coded API keys can be shared and require rotation, which can open them up to being compromised. Compromised credentials could allow access to OCI services outside of the expected radius.
- Remediation Procedure
From Console (Dynamic Groups):
- Go to https://cloud.oracle.com/identity/domains/
- Select a Compartment
- Click on the Domain
- Click on
Dynamic groups - Click Create Dynamic Group.
- Enter a Name
- Enter a Description
- Enter Matching Rules to that includes the instances accessing your OCI resources.
- Click Create.

1.15Ensure storage service-level admins cannot delete resources they manage0
Attributes
- Profile
Level 2
- Section
- Identity and Access Management
- Description
To apply the separation of duties security principle, one can restrict service-level administrators from being able to delete resources they are managing. It means service-level administrators can only manage resources of a specific service but not delete resources for that specific service.
Example policies for global/tenant level for block volume service-administrators:
Allow group VolumeUsers to manage volumes in tenancy where request.permission!='VOLUME_DELETE' Allow group VolumeUsers to manage volume-backups in tenancy where request.permission!='VOLUME_BACKUP_DELETE'Example policies for global/tenant level for file storage system service-administrators:
Allow group FileUsers to manage file-systems in tenancy where request.permission!='FILE_SYSTEM_DELETE' Allow group FileUsers to manage mount-targets in tenancy where request.permission!='MOUNT_TARGET_DELETE' Allow group FileUsers to manage export-sets in tenancy where request.permission!='EXPORT_SET_DELETE'Example policies for global/tenant level for object storage system service-administrators:
Allow group BucketUsers to manage objects in tenancy where request.permission!='OBJECT_DELETE' Allow group BucketUsers to manage buckets in tenancy where request.permission!='BUCKET_DELETE'- Audit Procedure
From Console:
- Login to OCI console.
- Go to Identity -> Policies, In the compartment dropdown, choose the compartment.
- Open each policy to view the policy statements.
- Verify the policies to ensure that the policy statements that grant access to storage service-level administrators have a condition that excludes access to delete the service they are the administrator for.
From CLI:
- Execute the following command:
for compid in `oci iam compartment list --compartment-id-in-subtree TRUE 2>/dev/null | jq -r '.data[] | .id'` do for policy in `oci iam policy list --compartment-id $compid 2>/dev/null | jq -r '.data[] | .id'` do output=`oci iam policy list --compartment-id $compid 2>/dev/null | jq -r '.data[] | .id, .name, .statements'` if [ ! -z "$output" ]; then echo $output; fi done done- Verify the policies to ensure that the policy statements that grant access to storage service-level administrators have a condition that excludes access to delete the service they are the administrator for.
- Assessment Status
Manual
- Rationale Statement
Creating service-level administrators without the ability to delete the resource they are managing helps in tightly controlling access to Oracle Cloud Infrastructure (OCI) services by implementing the separation of duties security principle.
- Remediation Procedure
From Console:
- Login to OCI console.
- Go to Identity -> Policies, In the compartment dropdown, choose the compartment. Open each policy to view the policy statements.
- Add the appropriate
wherecondition to any policy statement that allows the storage service-level to manage the storage service.

- Note each query can only be 14 days multiple queries will be required to go 45 days
- Click
Search - Expand the results
- If results the count is not zero the user has used their API key during that period
- Repeat steps 8 – 11 for the 45-day period
From CLI:
For Passwords:
- Execute the below:
oci identity-domains users list --all --endpoint <identity-domain-endpoint> --attributes urn:ietf:params:scim:schemas:oracle:idcs:extension:userState:User:lastSuccessfulLoginDate --profile Oracle --query '.data.resources[]|."user-name" + " " + ."urn-ietf-params-scim-schemas-oracle-idcs-extension-user-state-user"."last-successful-login-date"'- Review the output the that the date is under 45 days, or no date means they have not logged in
For API Keys:
- Create the search query text:
export query="search \"<tenancy-ocid>/_Audit_Include_Subcompartment\" | data.identity.credentials='*<key-finger-print>' | summarize count() by data.identity.principalId"- Select a day range. Date format is
2024-12-01
- Note each query can only be 14 days multiple queries will be required to go 45 days
- Execute the below:

- Section
- Compute
- Description
Compute Instances that utilize Legacy MetaData service endpoints (IMDSv1) are susceptible to potential SSRF attacks. To bolster security measures, it is strongly advised to reconfigure Compute Instances to adopt Instance Metadata Service v2, aligning with the industry's best security practices.
- Audit Procedure
From Console:
- Login to the OCI Console
- Select compute instance in your compartment.
- Click on each instance name.
- In the
Instance Detailssection, next toInstance metadata servicemake sureVersion 2 onlyis selected.
From CLI:

- Impact Statement
If you disable IMDSv1 on an instance that does not support IMDSv2, you might not be able to connect to the instance when you launch it.
IMDSv2 is supported on the following platform images:
- Oracle Autonomous Linux 8.x images
- Oracle Autonomous Linux 7.x images released in June 2020 or later
- Oracle Linux 8.x, Oracle Linux 7.x, and Oracle Linux 6.x images released in July 2020 or later
Other platform images, most custom images, and most Marketplace images do not support IMDSv2. Custom Linux images might support IMDSv2 if cloud-init is updated to version 20.3 or later and Oracle Cloud Agent is updated to version 0.0.19 or later. Custom Windows images might support IMDSv2 if Oracle Cloud Agent is updated to version 1.0.0.0 or later; cloudbase-init does not support IMDSv2.
- Assessment Status
Automated
- Rationale Statement
Enabling Instance Metadata Service v2 enhances security and grants precise control over metadata access. Transitioning from IMDSv1 reduces the risk of SSRF attacks, bolstering system protection.

- Description
Shielded Instances with Secure Boot enabled prevents unauthorized boot loaders and operating systems from booting. This prevent rootkits, bootkits, and unauthorized software from running before the operating system loads. Secure Boot verifies the digital signature of the system's boot software to check its authenticity. The digital signature ensures the operating system has not been tampered with and is from a trusted source. When the system boots and attempts to execute the software, it will first check the digital signature to ensure validity. If the digital signature is not valid, the system will not allow the software to run. Secure Boot is a feature of UEFI(Unified Extensible Firmware Interface) that only allows approved operating systems to boot up.

An existing instance cannot be changed to a Shielded instance with Secure boot enabled. Shielded Secure Boot not available on all instance shapes and Operating systems. Additionally the following limitations exist:
Thus to enable you have to terminate the instance and create a new one. Also, Shielded instances do not support live migration. During an infrastructure maintenance event, Oracle Cloud Infrastructure live migrates supported VM instances from the physical VM host that needs maintenance to a healthy VM host with minimal disruption to running instances. If you enable Secure Boot on an instance, the instance cannot be migrated, because the hardware TPM is not migratable. This may result in an outage because the TPM can't be migrate from a unhealthy host to healthy host.
- Assessment Status
Automated
- Rationale Statement
A Threat Actor with access to the operating system may seek to alter boot components to persist malware or rootkits during system initialization. Secure Boot helps ensure that the system only runs authentic software by verifying the digital signature of all boot components.

- Description
Using default tags is a way to ensure all resources that support tags are tagged during creation. Tags can be based on static or computed values. It is recommended to set up default tags early after root compartment creation to ensure all created resources will get tagged. Tags are scoped to Compartments and are inherited by Child Compartments. The recommendation is to create default tags like “CreatedBy” at the Root Compartment level to ensure all resources get tagged. When using Tags it is important to ensure that Tag Namespaces are protected by IAM Policies otherwise this will allow users to change tags or tag values. Depending on the age of the OCI Tenancy there may already be Tag defaults setup at the Root Level and no need for further action to implement this action.

5.1 Object Storage
- Description
A bucket is a logical container for storing objects. Object versioning is enabled at the bucket level and is disabled by default upon creation. Versioning directs Object Storage to automatically create an object version each time a new object is uploaded, an existing object is overwritten, or when an object is deleted. You can enable object versioning at bucket creation time or later.
- Audit Procedure
From Console:
- Login to OCI Console.
- Select
Storagefrom the Services menu. - Select

- Asset Management
- Description
When you sign up for Oracle Cloud Infrastructure, Oracle creates your tenancy, which is the root compartment that holds all your cloud resources. You then create additional compartments within the tenancy (root compartment) and corresponding policies to control access to the resources in each compartment.
Compartments allow you to organize and control access to your cloud resources. A compartment is a collection of related resources (such as instances, databases, virtual cloud networks, block volumes) that can be accessed only by certain groups that have been given permission by an administrator.
