The Intelligent Platform Management Interface (IPMI) is a set of computer interface specifications for an autonomous computer subsystem that provides management and monitoring capabilities independently of the host system's CPU, firmware (BIOS or UEFI) and operating system. IPMI defines a set of interfaces used by system administrators for out-of-band management of computer systems and monitoring of their operation. For example, IPMI provides a way to manage a computer that may be powered off or otherwise unresponsive by using a network connection to the hardware rather than to an operating system or login shell. Another use case may be installing a custom operating system remotely. Without IPMI, installing a custom operating system may require an administrator to be physically present near the computer, insert a DVD or a USB flash drive containing the OS installer and complete the installation process using a monitor and a keyboard. Using IPMI, an administrator can mount an ISO image, simulate an installer DVD, and perform the installation remotely.^[1]

The specification is led by Intel and was first published on September 16, 1998. It is supported by more than 200 computer system vendors, such as Cisco, Dell,^[2]Hewlett Packard Enterprise, Intel, OnLogic, Marvell Semiconductor, NEC Corporation, SuperMicro and Tyan.^[3][4]

The successor to the IPMI is Redfish.

Functionality[edit]

Using a standardized interface and protocol allows systems-management software based on IPMI to manage multiple, disparate servers. As a message-based, hardware-level interface specification, IPMI operates independently of the operating system (OS) to allow administrators to manage a system remotely in the absence of an operating system or of the system managementsoftware. Thus IPMI functions can work in any of three scenarios:

• before an OS has booted (allowing, for example, the remote monitoring or changing of BIOS settings)
• when the system is powered down
• after OS or system failure – the key characteristic of IPMI compared with in-band system management is that it enables remote login to the operating system using SSH

System administrators can use IPMI messaging to monitor platform status (such as system temperatures, voltages, fans, power supplies and chassis intrusion); to query inventory information; to review hardware logs of out-of-range conditions; or to perform recovery procedures such as issuing requests from a remote console through the same connections e.g. system power-down and rebooting, or configuring watchdog timers. The standard also defines an alerting mechanism for the system to send a simple network management protocol (SNMP) platform event trap (PET).

The monitored system may be powered off, but must be connected to a power source and to the monitoring medium, typically a local area network (LAN) connection. IPMI can also function after the operating system has started, and exposes management data and structures to the system management software. IPMI prescribes only the structure and format of the interfaces as a standard, while detailed implementations may vary. An implementation of IPMI version 1.5 can communicate via a direct out-of-band local area network (LAN) or serial connection or via a side-band local area network (LAN) connection to a remote client. The side-band LAN connection utilizes the board network interface controller (NIC). This solution is less expensive than a dedicated LAN connection but also has limited bandwidth.

Systems compliant with IPMI version 2.0 can also communicate via serial over LAN, whereby serial console output can be remotely viewed over the LAN. Systems implementing IPMI 2.0 typically also include KVM over IP, remote virtual media and out-of-band embedded web-server interface functionality, although strictly speaking, these lie outside of the scope of the IPMI interface standard.

DCMI (Data Center Manageability Interface) is a similar standard based on IPMI but designed to be more suitable for Data Center management: it uses the interfaces defined in IPMI, but minimizes the number of optional interfaces and includes power capping control, among other differences.

Side-band and out-of-band[edit]

As well as using a separate dedicated management LAN connection, IPMI also allows implementation of a so-called 'side-band' management LAN connection. This connection utilizes a System Management Bus (SMBUS) interface between the BMC (Baseboard Management Controller) and the board Network Interface Controller (NIC). This solution has the advantage of reduced costs but also provides limited bandwidth – sufficient for text console redirection but not for video redirection. For example, when a remote computer is down the system administrator can access it through IPMI and utilize a text console.

This suffices for a few vital functions, such as checking the event log, accessing the BIOS setup and performing power on, power off or power cycle. However, more advanced functions, such as remote re-installation of an operating system, may require a full out-of-band management approach utilizing a dedicated LAN connection.^{[citation needed]}

IPMI components[edit]

An IPMI sub-system consists of a main controller, called the baseboard management controller (BMC) and other management controllers distributed among different system modules that are referred to as satellite controllers. The satellite controllers within the same chassis connect to the BMC via the system interface called Intelligent Platform Management Bus/Bridge (IPMB) – an enhanced implementation of I²C (Inter-Integrated Circuit). The BMC connects to satellite controllers or another BMC in another chassis via the Intelligent Platform Management Controller (IPMC) bus or bridge. It may be managed with the Remote Management Control Protocol (RMCP), a specialized wire protocol defined by this specification. RMCP+ (a UDP-based protocol with stronger authentication than RMCP) is used for IPMI over LAN.

Several vendors develop and market BMC chips. A BMC utilized for embedded applications may have limited memory and require optimized firmware code for implementation of the full IPMI functionality. Highly integrated BMCs can provide complex instructions and provide the complete out-of-band functionality of a service processor. The firmware implementing the IPMI interfaces is provided by various vendors.A field replaceable unit (FRU) repository holds the inventory, such as vendor ID and manufacturer, of potentially replaceable devices. A sensor data record (SDR) repository provides the properties of the individual sensors present on the board. For example, the board may contain sensors for temperature, fan speed, and voltage.

Baseboard management controller[edit]

The baseboard management controller (BMC) provides the intelligence in the IPMI architecture. It is a specialized microcontroller embedded on the motherboard of a computer – generally a server. The BMC manages the interface between system-management software and platform hardware.

Different types of sensors built into the computer system report to the BMC on parameters such as temperature, cooling fanspeeds, power status, operating system (OS) status, etc.The BMC monitors the sensors and can send alerts to a system administrator via the network if any of the parameters do not stay within pre-set limits, indicating a potential failure of the system. The administrator can also remotely communicate with the BMC to take some corrective actions – such as resetting or power cycling the system to get a hung OS running again. These abilities save on the total cost of ownership of a system.

Systems compliant with IPMI version 2.0 can also communicate via serial over LAN, whereby serial console output can be remotely viewed over the LAN. Systems implementing IPMI 2.0 typically also include KVM over IP, remote virtual media and out-of-band embedded web-server interface functionality, although strictly speaking, these lie outside of the scope of the IPMI interface standard.

Physical interfaces to the BMC include SMBuses, an RS-232serial console, address and data lines and an Intelligent Platform Management Bus (IPMB), that enables the BMC to accept IPMI request messages from other management controllers in the system.

A direct serial connection to the BMC is not encrypted as the connection itself is secure. Connection to the BMC over LAN may or may not use encryption depending on the security concerns of the user.

There are rising concerns about general security regarding BMCs as a closed infrastructure.^[5][6][7][8]OpenBMC is a Linux Foundation Collaborative open-source BMC project.^[9]

Security[edit]

Historical issues[edit]

On 2 July 2013, Rapid7 published a guide to security penetration testing of the latest IPMI 2.0 protocol and implementations by various vendors.^[10]

Some sources in 2013 were advising against using the older version of IPMI,^[5] due to security concerns related to the design and vulnerabilities of Baseboard Management Controllers (BMCs).^[11][12]

However, like for any other management interface, best security practices dictate the placement of the IPMI management port on a dedicated management LAN or VLAN restricted to trusted Administrators.^[13]

Latest IPMI specification security improvements[edit]

However, this is only of historical value. The IPMI specification has been updated with RAKP+ and a stronger cipher that is computationally impractical to break.^[14] Vendors as a result have provided patches that remediate these vulnerabilities.^{[citation needed]}

The DMTF organization has developed a secure and scalable interface specification called Redfish to work in modern datacenter environments.^[15]

Potential solutions[edit]

I-view Communication Driver Job

Some potential solutions exist outside of the IPMI standard, depending on proprietary implementations. The use of default short passwords, or 'cipher 0' hacks can be easily overcome with the use of a RADIUS server for Authentication, Authorization, and Accounting over SSL as is typical in a datacenter or any medium to large deployment. The user's RADIUS server can be configured to store AAA securely in an LDAP database using either FreeRADIUS/OpenLDAP or Microsoft Active Directory and related services.

Role-based access provides a way to respond to current and future security issues by increasing amounts of restriction for higher roles.Role-based access is supported with three roles available: Administrator, Operator and User.

Overall, the User role has read-only access of the BMC and no remote control ability such as power cycle or the ability to view or log into the main CPU on the motherboard. Therefore, any hacker with the User role has zero access to confidential information, and zero control over the system. The User role is typically used to monitor sensor readings, after an SNMP alert has been received by SNMP Network Monitoring Software.

The Operator role is used in the rare event when a system is hung, to generate an NMI crash/core dump file and reboot or power cycle the system.In such a case, the Operator will also have access to the system software to collect the crash/core dump file.

The Administrator role is used to configure the BMC on first boot during the commissioning of the system when first installed.

Therefore, the prudent best practice is to disable the use of the Operator and Administrator roles in LDAP/RADIUS, and only enable them when needed by the LDAP/RADIUS administrator. For example, in RADIUS a role can have its setting Auth-Type changed to:

Doing so will prevent RAKP hash attacks from succeeding since the username will be rejected by the RADIUS server.
