Getting started with Guard
概要
この設定ガイドでは、Atlassian Guard トライアルの設定手順を順に説明します。このガイドには、ベスト プラクティスの推奨事項に従った手順が含まれています。ただし、組織固有の要件によっては、一部の制御は不要です。
はじめに
組織の可視性を高め、ユーザーのアクセスを効果的に管理するために、この 3 つのステップから企業の保護を始めましょう。
Manage how users log in with authentication policies
A strong authentication policy can help prevent the risk of compromised accounts from accessing your data. Since teams and users can access a variety of tools and information, you have the control to make different requirements apply to different sets of users.
Authentication policy capabilities include:
- Enforce two-step verification or single sign-on
- Create different authentication policies for different cohorts of users
- Create authentication policy for external users
- Get alerts when authentication policies are changed (Premium only)
Automatically provision users
Avoid manual, error-prone processes by connecting to your existing identity provider to automate user provisioning. By specifying a SCIM schema, you can automatically create accounts and update group memberships, providing your users with the right product access for their role or business unit. By automatically removing users when they leave your organization, you avoid paying for users who no longer need access.
User provisioning capabilities include:
- Connect an identity provider and automatically provision users
- Automatic sync new users, removes old users, and updates group memberships for existing users
Control user API tokens
User API tokens are used to perform actions using the API. They are tied to individual users, and if compromised, they can present a huge risk to your organization. As an admin, you can gain control and visibility into the user API token lifecycle with Guard.
API token control capabilities include:
- Revoke API tokens so they can no longer be used
- Get alerts when tokens are created or revoked (Premium only)
組織とドメインの検証
ドメイン検証の流れ
たとえば、あなたの会社が Acme Inc. という名前で、「acme.com」と「acme.co.uk」というドメインを所有しているとします。
管理者は組織を設定した後、組織ビューの [Directory (ディレクトリ)] > [Domains (ドメイン)] ページからこれらのドメインの所有権を検証します。ドメインの Web サイトのルート フォルダーに HTML ファイルをアップロードするか、TXT レコードを自社のドメイン ネーム システム (DNS) にコピーします。
いずれかのステップが完了したら、「Verify（検証）」をクリックします。「jack@acme.com」や「jill@acme.co.uk」など、これらのドメインのメール・アドレスを使ってアカウントを設定したアトラシアンのクラウド・ユーザーを組織の一部として管理できるようになります。
ドメインを検証すると、現在は管理していないサイトと製品の Atlassian アカウントも管理することになります。たとえば、Atlassian クラウド製品に登録したものの、まだ管理下に置かれていないチームや従業員が企業に存在するとします。ドメインを検証する前に、社内で Atlassian クラウド製品を使っている他のサイト管理者やチームに通知して、今後の変更を知らせておくことをお勧めします。
組織の管理者がドメインを検証したら、そのドメインに属しているメール アドレスのある Atlassian ユーザーのプロファイル設定に、組織によってアカウントが管理されるようになったことを知らせるメッセージが表示されます。
組織の管理対象アカウントページにアクセスすると各アカウントのユーザー情報を編集できます。セキュリティポリシーを適用して Atlassian Guard をサブスクライブする場合、管理者が設定したポリシーが管理対象アカウントのユーザーに適用されます。
Use security policies to reduce the risk of data loss
Loss of sensitive company data can be disastrous for an organization. Jira and Confluence capabilities designed to aid collaboration, such as export, public links, and public access, can become a risk when handling confidential, commercially sensitive, or otherwise mission-critical user-generated content.
Data security and mobile app management (MAM) policies help you govern how users, apps, and people outside of your organization interact with content, such as Confluence pages and Jira issues, and reduces the risk of data leaving the applications you control.
Data security and mobile policy capabilities include:
- Create data security policies to restrict actions like export, public links, and anonymous access
- Use a mobile app policy to block screenshots, screen recording, downloads, and more
- Apply data security policies to classified data (Premium only)
Classify your data based on sensitivity levels
Data classification is the process of labeling information. It serves as the foundation of a data governance strategy in many organizations, particularly those that need to comply with government or other regulatory requirements. By adding classification levels with Guard, your space and project admins can set a default level for their space or project, and users can classify individual pages and issues.
Data classification capabilities, exclusive to Guard Premium, include:
- Manage organization-wide classification levels
- Apply classification levels to Confluence and Jira content
- Use data security policies to block actions like export, public links, and more for classified content
- Get an alert when the classification level of content changes
SAML シングルサインオン
SAML SSO とは
SAML シングル・サインオン（SSO）では、企業の既存の ID プロバイダーを使って Atlassian クラウド製品を認証できます。つまり、ユーザー名とパスワードだけではなくより安全な認証方法を使いながら、同じ認証情報で複数のツールにアクセスできるのです。
Gain insights into product usage and security practices
As an admin, you may struggle with resource allocation or security risk management due to limited visibility into how your teams are using Atlassian cloud products. Guard gives you visibility into your organization’s product usage, shadow IT, and users’ security posture, so you can make informed, data-driven decisions.
Capabilities that enhance visibility include:
- Get insights into active users and authentication methods
- View products created by managed users, administered outside of your organization
Access organization-wide audit logs
When it comes to diagnosing issues or answering questions around user activity in detail, you need to be able to access and examine that data easily. With audit logs in Guard, you can track key activities that occur within your Atlassian organization. Use these activities to diagnose problems or questions related to user details, product access, managed accounts, and organization settings.
Audit log capabilities include:
- View audit logs for administrator activity, such as changes to user access
- View audit logs for user-created activity (Premium only)
- Track user API token usage (Premium only)
- Use webhooks to send audit log events to a third-party tool (Premium only)
SCIM 自動ユーザー プロビジョニング
ユーザーのプロビジョニングと解除とは
ユーザーをプロビジョニングまたは解除することによって、外部ディレクトリで設定したルールでアトラシアンのクラウド製品へのアクセスを定義できます。ユーザーの登録と登録解除は、外部ディレクトリにユーザーを追加または削除した際に自動的に実行されます。このようなユーザーディレクトリは通常、ID プロバイダーと呼ばれるソフトウェアベンダーからサービスとして提供されます。Atlassian Guard を使うと、アトラシアンのクラウド製品を ID プロバイダーと統合できます。
Detect suspicious user activity
Get alerts when certain types of user activity are detected, such as authorization and access events, data exfiltration events, product and integration configuration changes across Atlassian Administration, Jira, and Confluence.
With alerts, you have the information you and your security team need to thoroughly investigate the alert and remediate, if necessary.
Activity detection capabilities, exclusive to Guard Premium, include:
- Get an alert when detection criteria is met
- Send alerts to your existing SIEM or messaging tool
- Exclude specific users to reduce the number of false positive alerts
Detect sensitive data and data misuse
When work happens in Confluence and Jira, there’s always a chance someone includes data that shouldn’t be stored in your Atlassian cloud products, such as credit card numbers, API tokens, or AWS access keys.
Get alerts when certain types of sensitive data are added to a page or issue, allowing your security team to investigate and remove the data if appropriate.
Content scanning capabilities, exclusive to Guard Premium, include:
- Get alerts when common types of sensitive data are added
- Create custom detections for terms, phrases, and patterns
- Exclude selected pages or issues to reduce the number of false positive alerts
- Integrate with your existing SIEM or other tools
Investigation and remediation
Investigation and remediation are critical steps in cybersecurity incident response. It involves the process of identifying, analyzing, and understanding the nature and scope of a security incident, followed by taking any necessary actions to resolve the incident and mitigate its impact on the organization.
Respond to alerts
Security risks can go unnoticed and it can escalate and cause significant harm to your organization if it is not promptly identified and addressed. As an admin or security professional, you can quickly identify risks and take immediate action to prevent further damage. By regularly investigating alerts, you can fine-tune security measures and policies for your organization.
Investigation capabilities, exclusive to Guard Premium, include:
- Use suggested investigation steps to better understand the alert
- View information about the actor, to help determine whether the activity is suspicious
- See contextual data on the alert and the actor, such as an activity timeline panel
Remediation actions
When a security threat arises, a delayed response can increase the risk and impact of the threat. To help streamline your response, each alert has its own set of recommended remediation steps. These are provided to help your team act quickly to minimize the security impact of the potentially risky activity or data misuse.
Remediation capabilities, exclusive to Guard Premium, include:
- Use suggested remediation steps to streamline your response
- Take immediate steps to stop any further activity from happening, such as suspending the actor
- Update policies and settings to strengthen enforcement
- Automate common remediation actions, such as restricting the page or redacting data (coming soon)
