          Configuring Secure Boot for an ECS

          +

          Scenarios

          Secure boot is used to check the integrity of each component (driver loader, kernel, and kernel driver) during device startup. This prevents security threats to the system and user data caused by loading and running unauthenticated components.

          +

          Secure boot is a feature of the Unified Extensible Firmware Interface (UEFI) that requires all low-level firmware and software components to be verified before being loaded. During the boot process, UEFI secure boot checks the signature of each boot software, including the UEFI firmware driver (or option ROM), Extensible Firmware Interface (EFI) application, OS driver, and binary files. If the signature is valid or recognized by the original equipment manufacturer (OEM), the device will boot, and the firmware will hand over control to the OS.

          +
          Secure boot uses key pairs to sign and verify boot devices, ensuring that ECSs only boot software signed by encryption keys. This protects software from threats during the boot process. The secure boot key is stored in the key database of the UEFI non-volatile variable storage.
          • After secure boot is enabled, the system verifies component integrity during system startup, which does not affect services.
          • After secure boot is disabled, the system does not verify component integrity during system startup, which does not affect services.
          +
          +
          +

          Background

          UEFI is a standard that describes a new type of interface. It enables an OS to automatically load from a pre-boot operating environment to an OS.

          +

          The OSs that use the UEFI boot mode support secure boot. Secure boot provides verification of the boot chain status to ensure that only encrypted and verified UEFI binary files are executed after the firmware is initialized. These binary files include UEFI drivers, primary boot loaders, and chain loading components.

          +

          By default, secure boot is disabled and the system is in SetupMode. When the system is in SetupMode, all key variables can be updated without a cryptographic signature. After secure boot is enabled, the system exits SetupMode.

          +

          After secure boot is enabled, the system enforces signature validation on any UEFI binary files.

          +
          +

          Secure boot uses key databases in a chain of trust, as shown in Table 1. These databases are stored in the UEFI variable storage.

          + +
          + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

          +
          +

          Creating Secure Boot Keys (Linux)

          You need to create keys based on the UEFI secure boot standard, create a certificate for each key, convert each certificate into a UEFI signature list (binary file), and sign each certificate using the related key.

          +
          1. Create a globally unique identifier (GUID).

            Before creating a key pair, create a GUID for key generation.

            +
            1. Connect to an ECS.
            2. Create a GUID for key generation.
              uuidgen --random > GUID.txt
              +
            +

          2. (Mandatory) Create a platform key (PK).

            A PK is the root of trust for the UEFI secure boot instance.

            +
            1. Create a key and name the variable PK.
              openssl req -newkey rsa:4096 -nodes -keyout PK.key -new -x509 -sha256 -days 3650 -subj "/CN=Platform key/" -out PK.crt
              +

              Parameters in this command are described as follows:

              +
              • keyout PK.key: the private key file
              • days 3650: the certificate validity period
              • out PK.crt: the certificate for creating a UEFI variable
              • CN=Platform key: common name (CN) of the key. You can enter the name of your enterprise instead of the platform key.
              +
            2. Create a certificate.
              openssl x509 -outform DER -in PK.crt -out PK.cer
              +
            3. Convert the certificate into a UEFI signature list.
              cert-to-efi-sig-list -g "$(< GUID.txt)" PK.crt PK.esl
              +
            4. Use the private PK to sign the UEFI signature list.
              sign-efi-sig-list -g "$(< GUID.txt)" -k PK.key -c PK.crt PK PK.esl PK.auth
              +
            +

          3. (Mandatory) Create a key exchange key (KEK).

            The private KEK is used to add keys to the signature database (DB), which is the list of authorized signatures to boot on the system.

            +
            1. Create a key.
              openssl req -newkey rsa:4096 -nodes -keyout KEK.key -new -x509 -sha256 -days 3650 -subj "/CN=Key Exchange Key/" -out KEK.crt
              +
            2. Create a certificate.
              openssl x509 -outform DER -in KEK.crt -out KEK.cer
              +
            3. Convert the certificate into a UEFI signature list.
              cert-to-efi-sig-list -g "$(< GUID.txt)" KEK.crt KEK.esl
              +
            4. Use the private PK to sign the signature list.
              sign-efi-sig-list -g "$(< GUID.txt)" -k PK.key -c PK.crt KEK KEK.esl KEK.auth
              +
            +

          4. (Mandatory) Create a signature database (DB).

            The DB list contains the authorized keys that are allowed to boot on the system. To modify the list, you must have a private KEK.

            +

            Boot images will be signed with the private key that is created in this step.

            +
            1. Create a key.
              openssl req -newkey rsa:4096 -nodes -keyout db.key -new -x509 -sha256 -days 3650 -subj "/CN=Signature Database key/" -out db.crt
              +
            2. Create a certificate.
              openssl x509 -outform DER -in db.crt -out db.cer
              +
            3. Convert the certificate into a UEFI signature list.
              cert-to-efi-sig-list -g "$(< GUID.txt)" db.crt db.esl
              +
            4. Use the private KEK to sign the signature list.
              sign-efi-sig-list -g "$(< GUID.txt)" -k KEK.key -c KEK.crt db db.esl db.auth
              +
            +

          5. (Optional) Create a forbidden signatures database (DBX).

            The DBX disables specific DB certificates. It can be a certificate list or a hash list.

            +

          6. (Optional) Create a timestamp signatures database (DBT).

            The DBT database signs signature timestamps. If the DB certificate is in the DBX and the DBX specifies the revocation time, the DB certificate can be used for signature verification only if the signature time is earlier than the revocation time.

            +

          +
          +

          Signing ECS Images Using Keys

          For Ubuntu, sign the kernel file and boot file.

          +

          +
          +
          +

          Obtaining a Secure Boot Certificate

          Contact the image provider to obtain a secure boot certificate.

          +
          +

          Transcoding the Secure Boot Certificate

          • Platform Key (PK) transcoding
            __platform_key=$(cat PK.cer | base64 -w 0)
            +
          +
          • Key Exchange Key (KEK) transcoding
            __key_exchange_key=$(cat KEK.cer | base64 -w 0)
            +
          +
          • Signature Database (DB) transcoding
            __signature_database=$(cat db.cer | base64 -w 0)
            +
          +
          • Forbidden Signatures Database (DBX) transcoding
            __forbidden_signatures_database=$(cat dbx.cer | base64 -w 0)

            __timestamp_signatures_database=$(cat dbt.cer | base64 -w 0)
            +
          +
          • PK.cer is the platform key (PK) certificate.
          • KEK.cer is the Key Exchange Key (KEK) certificate.
          • db.cer is the Signature Database (DB) certificate.
          • dbx.cer is the Forbidden Signatures Database (DBX) certificate.
          • dbt.cer is the Timestamp Signatures Database (DBT) certificate.
          +
          +
          +

          Creating a Private Image

                Resetting the Password of a Linux ECS by Attaching a System Disk to a Temporary ECS

                Scenarios

                Keep your password secure. Reset the password if:

                • The password is forgotten.
                • The password has expired.

                This section describes how to reset the root password. After resetting the password, you can log in to the ECS and change the keys or reset passwords for non-root users.

                Prerequisites

                • A backup has been created for the system disk. For details, see Backing Up an ECS.
                • A temporary Linux ECS is available. It is located in the same AZ and has the same CPU architecture as the target ECS.
                • You have bound an EIP to the temporary ECS.

                Procedure

                1. Download the script for resetting the password and upload the script to the temporary ECS.

                  Contact customer service to obtain the password reset script. Use a connection tool, such as WinSCP, to upload the obtained changepasswd.sh script to the temporary ECS.

                  To download WinSCP, log in at https://winscp.net/.

Notes

  • After the OS is reinstalled, the IP and MAC addresses of the ECS remain unchanged.
  • Reinstalling the OS clears the data in all partitions of the system disk, including the system partition. Back up data before reinstalling the OS. For details, see Backing Up an ECS.
  • Reinstalling the OS does not affect data in data disks.
  • Do not perform any operations on the ECS immediately after its OS is reinstalled. Wait for several minutes until the system successfully injects the password or key. Otherwise, the injection may fail, and the ECS cannot be accessed.
  • After the OS is reinstalled, the password for logging in to the ECS is reset. To retrieve the password, perform the following operations:
  • You can choose to encrypt the system disk of an ECS during OS reinstallation.

      Adding an ECS to an ECS Group

      To improve service reliability, you can add ECSs to an ECS group so that these ECSs in this group can run on different hosts.

      • After an ECS is added to an ECS group, the system reallocates a host to run this ECS to ensure that ECSs in this group run on different hosts. When you attempt to restart the ECS, the startup may fail due to insufficient resources. In such a case, remove the ECS from the ECS group and try to restart the ECS again.
      • ECSs with local disks can be added to an ECS group only during the creation process. Once created, they cannot be added to any ECS groups.
      • ECSs that have local disks, GPU cards, or FPGA cards attached can be added to an ECS group only during the creation process. Once created, they cannot be added to any ECS groups.

      General-Purpose ECSs

      -

      Overview

      General-purpose ECSs provide a balance of compute, memory, and networking resources and a baseline level of vCPU performance with the ability to burst above the baseline. These ECSs are suitable for applications with general workloads, such as web servers, enterprise R&D, and small-scale databases.

      Overview

      General-purpose ECSs provide a balance of compute, memory, and networking resources and a baseline level of vCPU performance with the ability to burst above the baseline. These ECSs are suitable for applications that do not always utilize full vCPU performance but occasionally burst, such as web servers, enterprise R&D, and small-scale databases.

      S9 ECSs use the sixth-generation Intel® Xeon® Scalable processors and KVM virtualization to provide enhanced compute, network, and security performance as well as better cost-effectiveness. If you have requirements on performance stability, you can optimize the performance by referring to Best Practices for Performance Configuration to reduce the ping and TCP/UDP latency.

      S7n ECSs use the 3rd generation Intel® Xeon® Scalable processors and 25GE high-speed intelligent NICs to provide high network bandwidth and packets per second (PPS) at the lowest possible price.

      S3 ECSs are suitable for applications that require moderate performance generally but occasionally burstable high performance, such as light-workload web servers, enterprise R&D and testing environments, and low- and medium-performance databases.

      S2 ECSs use Intel® Xeon® Scalable processors, which significantly improve the comprehensive performance. They provide a balance of compute, memory, and networking resources and a baseline level of vCPU performance with the ability to burst above the baseline. These ECSs are suitable for the scenarios where vCPU performance is not often (or always) used but is occasionally used.

            ECSs run on physical hosts. Although there are multiple mechanisms to ensure system reliability, fault tolerance, and high availability, host hardware might be damaged or power failures might occur. If physical hosts cannot be powered on or restarted due to damage, CPU and memory data will be lost and live migration cannot be used to recovery ECSs.

            The cloud platform provides automatic recovery by default to restart ECSs through cold migration, ensuring high availability and dynamic ECS migration. If a physical host accommodating ECSs breaks down, the ECSs will automatically be migrated to a functional physical host to minimize the impact on your services. During the process, the ECSs will restart.

            • Auto recovery does not ensure user data consistency.
            • An ECS can be automatically recovered only if the physical server where the ECS resides becomes faulty. This function does not take effect if the fault is caused by the ECS itself.
            • An ECS can be automatically recovered only after the physical server where the ECS resides is shut down. If the physical server is not shut down due to a fault, for example, a memory fault, auto recovery fails to take effect.
            • An ECS can be automatically recovered only once within 12 hours if the physical server where the ECS resides becomes faulty.
            • ECS auto recovery may fail in the following scenarios:
              • No physical server is available for migration due to a system fault.
              • The target physical server does not have sufficient temporary capacity.
