The information below is taken from the HPE iLO help documentation and is provided here for convenience sake – SSH cipher, key exchange, and MAC support I would strongly recommend deploying any HPE hardware with iLO functionality in ‘HighSecurity’ mode, let us hope that when TLS 1.3 is widely available iLO 5 supports and provides similar configuration options.

To install these component types, use Smart Update Manager to add files or install sets to the iLO installation queue, or install each update individually by using the iLO Firmware or Group Firmware Updatepages You cannot use Smart Update Manager to directly install iLO Secure Flash components, TPM components, or NVDIMM components.The HPQLOCFG utility negotiates an SSL connection to iLO and then uses the strongest available cipher to send RIBCL scripts to iLO over the network.Remote Console data uses AES-128 bidirectional encryption.User name and password restrictions for iLO RESTful API and RIBCL commands executed from the host system are enforced when iLO is configured to use this security state.This security state does not affect communications and connections over less-secure channels When HighSecurity is enabled, you must use a supported cipher to connect to iLO through these secure channels. iLO enforces the use of AES ciphers over the secure channels, including secure HTTP transmissions through the browser, SSH port, iLO RESTful API, and RIBCL.HPE provide the following information on ‘HighSecurity’ mode – If you are using the standalone iLO remote console you will need to update to the latest version to make sure it supports the AES ciphers. It is vital you ensure browsers and other systems which connect will support this change. Please be mindful that any change to protocol and cipher settings may impair your ability to connect and manage the iLO system. Now we can only negotiate a TLS 1.2 protocol option with a limited set of AES ciphers. nmap -p –script ssl-enum-ciphers Īs you can see a wide range of options can be negotiated, not let’s look at an iLO configured for ‘HighSecurity’ mode –.If you are interested, the command syntax required is as follows: First we will look at the default ‘Production’ setting and see what can be negotiated. There are a number of ways we can validate what protocols and ciphers are supported – in this instance I will use NMAP. I am assuming of course that you will have replaced the TLS/SSL certificate with a valid CA signed certificate, self-signed just should not exist in any environment – especially when it is easy to create an internal PKI infrastructure. Having made the change and clicked ‘Apply’ it is necessary to allow the iLO subsystem to restart to make the necessary changes. By default this is set to ‘Production’, in my second screenshot I’ve changed this to ‘HighSecurity’ and for those of you who require FIPS compliance there is a final option of FIPS.

Let’s have a look at the web interface – if we browse to the iLO and then Security -> Encryption we see a drop down menu. With TLS 1.3 here I’d love to say I’ll work to 1.3 only but that is a way off yet for us. I am working towards a TLS 1.2 only environment at work which is not easy with so many systems and requirements but it is a worthy goal. To do so we will modify the settings to only support TLS 1.2 as a protocol with a reduced set of ciphers that only use AES. Now that the introduction is out of the way let’s take a look at configuring an iLO interface to be somewhat more secure than it is by default.

The most recent version was released alongside their tenth generation server hardware (Gen10) – iLo 5 brings many features in both the software and hardware which are outside the scope of this post, for your reference I have provided a link to the iLO homepage on HPE below – If you’re not familiar, HPE provide IPMI functionality via a custom ASIC which they call their Integrated Lights Out (iLO) chip. In this post I’m going to cover some of the nice features in Hewlett Packard Enterprise (HPE) latest iLO. People who work with me or have done in the past will know I’m really keen on ensuring TLS/SSL settings and certificates are properly implemented wherever possible.
