Um fornecedor terceirizado ameaça sua segurança multinuvem. Como você protegerá seus dados?

- Strict IAM Policies should be designed with least privilege accesses. - Zero trust model should be used to avoid unnecessary access grants among team members. - Data must be Encrypted at rest and in transit as the project is hosted in a multi-cloud environment. - Vendors' resources must be trained and educated to match the expectations with security compliance.

Don’t let a vendor be your weakest link. Protect your data proactively: 1. Vet your vendors Thoroughly assess their security protocols and compliance standards. 2. Implement zero trust architecture Limit access to only what is necessary, and continuously monitor. 3. Regularly audit and update Ensure third-party access and security measures are up to date and align with your policies.

Vendor Due Diligence Prior to partnering with any external vendor, it's imperative to conduct a comprehensive evaluation of their security posture. This includes assessing their security policies, practices, and incident response capabilities. Request detailed information on their data security and privacy measures, and ensure they have robust safeguards in place. Establish clear contractual agreements that outline security expectations and responsibilities for both parties. Regularly review these agreements and monitor the vendor's adherence to them to maintain the ongoing protection of your sensitive data.

Access control and Data Encryption are the best answers to this question. Vetting really just reduces your per-application load; it is easier to deal with only one or two problem vendors than a whole fleet of them. You should assume that over a long enough period of time all data trusted to a vendor will be compromised. Provided there were always role restrictions in place, the most sensitive information in the cloud is in a vault decoupled from all context, and sensitive information especially including PII and authentications was always encrypted and stored separately from keys, the value of any compromised system is reduced dramatically. One thing not on this list : be wary of leadership that insists on testing over real data.

Pentest'em In brazil we have the term "puxar a capivara" Its essential to pull and gather all information concerning externals, but you are not the FBI. So what I recommend is to encapsulate all vendors with strict policy, access rules, from network to application, and monitor and log activity constantly, that is, not just "before integrating vendors", of course!!!!

Bolstering Multi-Cloud Security with Robust Access Controls To safeguard your multi-cloud environment, stringent access controls are paramount. Third-party vendors should be granted only the minimum level of access required to fulfill their duties. Utilize identity and access management (IAM) tools to effectively manage permissions. Regularly audit and update access rights to prevent privilege creep, where users may accumulate unnecessary permissions over time. By adopting a principle of least privilege, you can significantly reduce the risk of unauthorized data exposure.

Access Control: In my experience, stringent access control is key in a multi-cloud setup. I managed vendor access by strictly limiting it to what was necessary, using IAM tools to enforce permissions. Regular reviews of access rights helped prevent privilege creep, ensuring no one had more access than needed. Implementing least-privilege access was crucial; it reduced the risk of unauthorized data exposure and kept our environment secure. This approach has proven effective in maintaining tight security across multiple clouds. 🔒

- Implement Stringent Access Controls: Establish and enforce strict access control policies to safeguard your multi-cloud environment. Ensure that third-party vendors are granted only the necessary level of access required to perform their functions. - Utilize IAM Tools: Use identity and access management (IAM) tools to manage permissions effectively. Regularly review and update access rights to prevent privilege creep, where users accumulate more access privileges than needed over time. - Employ Least Privilege Access: Adopt the principle of least privilege access to minimize the risk of unauthorized data exposure. Ensure that users and systems have only the minimum access necessary to perform their tasks.

Implement Least Privilege Access: Ensure that the vendor only has the minimum necessary access to your systems. Use role-based access control (RBAC) to restrict permissions, allowing access only to specific resources that the vendor needs. Use Identity and Access Management (IAM): Leverage IAM policies to enforce granular access controls across your cloud environments. This includes setting up time-bound access, conditional access based on location or device, and regularly reviewing and revoking unused access permissions. Enable Multi-Factor Authentication (MFA): Require MFA for all access, especially for privileged accounts that the vendor might use. This adds an extra layer of security, reducing the risk of unauthorized access.

Ich habe schon oft erlebt, dass die Dokumentation eines Third Party Services eine privilegierte Adminrolle für die Bereitstellung von Funktionalität verlangt. Oftmals ist nach Rückfrage beim Hersteller diese Rolle nicht zwingend notwendig. Achte darauf, dass du nur die Berechtigungen erteilst, die tatsächlich notwendig sind. Nutze für jede Applikation ein eigenes Service Principal. Überprüfe regelmäßig, ob die Accounts noch benötigt werden. Am besten erstellst du sie mit einer definierten Lifetime und verlängerst sie bei Bedarf. Du kannst du sicherstellen, dass Applikationen nicht zu hohe Berechtigungen haben und im Worst Case ausgenutzt werden.

Robust Data Encryption: A Cornerstone of Cloud Security Safeguarding sensitive data in a multi-cloud environment demands a robust encryption strategy. By encrypting data both at rest (while stored) and in transit (while being transferred), you create a formidable barrier against unauthorized access, even in the event of breaches.

Data encryption is essential for securing sensitive information in a multi-cloud setup. Encrypting data both at rest and in transit ensures protection against unauthorized access. Strong encryption standards are a must, along with careful management of encryption keys—keeping them secure and separate from the data they protect. Implementing a Cloud Access Security Broker (CASB) can streamline encryption management across different cloud services, providing enhanced control and security. This approach has consistently proven effective in safeguarding data across various cloud environments. 🔐

Key Elements of Effective Monitoring: SIEM Implementation: Leverage security information and event management (SIEM) systems to centralize and analyze security logs from all cloud services. Alert Configuration: Establish alerts for anomalous behavior that may signal a security breach, enabling timely response. Regular Auditing: Conduct routine audits to assess the environment's security posture and identify vulnerabilities. Penetration Testing: Employ penetration testing to simulate attacks and uncover potential weaknesses before they can be exploited by malicious actors.

In a multi-cloud environment, the best solution combines continuous monitoring with proactive security measures. Use a robust SIEM system to aggregate and analyze logs across all services, setting up real-time alerts for suspicious activity. Regularly audit your cloud environment and perform penetration testing to uncover vulnerabilities. What you typically use might suffice, but for best practices, ensure your SIEM integrates with all cloud platforms, automate responses where possible, and establish clear incident response protocols. This layered approach enhances security and ensures swift threat detection and mitigation.

Set Up Real-Time Monitoring: Implement continuous monitoring of all vendor activities across your multi-cloud environment. Use security information and event management (SIEM) tools to collect and analyze logs in real-time, flagging any suspicious activities. Establish Alerts and Automated Responses: Configure alerts for unusual behavior, such as access from unfamiliar IP addresses or attempts to access restricted data. Automate responses to these alerts, like temporarily suspending access until further investigation. Regular Audits and Reviews: Conduct regular audits of vendor access and activities. Review the logs to ensure compliance with your security policies and to identify any potential security gaps that need addressing.
