Businesses today are aware of the importance of regularly updating the different software they use to keep these running optimally and protected against cyberthreats. However, they often overlook the firmware of their computers and other devices. At best, firmware is only updated if there’s an issue with the hardware. But it’s actually a good idea to always keep firmware updated, and here’s why.

What is firmware?

Firmware is a basic type of software that is embedded into every hardware component in computers, computer peripherals (e.g., keyboards, mice), printers, mobile devices, and Internet of Things devices. It’s also found in some household appliances and gadgets such as TV remote controls, as well as everyday objects like traffic lights.

Essentially, firmware controls the device it’s installed on, sending instructions for how the device communicates with its different hardware components. It is only compatible with the make and model of the particular hardware it is installed on, and it cannot be uninstalled or deleted.

Why is updating firmware important?

According to Microsoft’s 2021 Security Signals report, firmware attacks are on the rise. These attacks involve injecting malware into computer systems to tamper with the firmware on motherboards or hardware drivers. From there, cybercriminals can do any number of things to the infected computers, including remotely controlling the devices, disabling the antivirus software, exfiltrating data, and blocking access to the devices and the data they contain.

Experts recommend installing firmware updates as soon as these become available to effectively protect against firmware attacks and other threats to your business’s cybersecurity. Users will also enjoy increased speed and enhanced performance with a firmware update.

How to install firmware updates

The method for updating firmware differs from device to device. For instance, you can simply download and install firmware updates on both iOS and Android devices. However, for devices such as routers, you will have to apply firmware updates from the manufacturer’s website or administrative console.

Keep in mind, however, that updating firmware can be tedious and time-consuming. In some cases, a firmware update can reset your devices and restore factory settings, causing you to lose custom configurations on your computers, routers, and the like. And if you fail to follow the manufacturer’s instructions to the letter, you risk damaging your systems.

It’s therefore best to leave the installation of firmware updates to the experts. For more information about firmware security and how to safely install firmware updates, or for any questions related to business IT, give our specialists a call today.

Obsolete Firmware

Are you still hanging on to your old work computers since they “still work fine”? While they may still help you get the job done, their outdated firmware can make you vulnerable to security risks that can lead to major problems.

What is firmware?

Firmware is a basic type of software that is embedded into every piece of hardware. It controls the device it’s installed on, cannot be uninstalled or removed, and is only compatible with the make and model of the hardware it is installed on. Think of it like a translator between your stiff and unchanging hardware and your fluid and evolving software. For example, the firmware of a TV remote control processes the button presses and sends that data into a format that the TV can understand.

Why is firmware security important?

To clearly explain the importance of firmware security, let’s use the firmware installed in a router as an example.

When you buy a router and plug it in, its firmware allows it to connect devices to your wireless network with almost zero input from you. However, if the router manufacturer is outside of California, then they might still be using the same username and password for the same router model, if not for all router models. If you don’t change these default settings, you could be exposed to hackers.

Default usernames and passwords is an example of a known vulnerability, and firmware could have other vulnerabilities that cybercriminals could exploit. Black hat hackers could use these to spy on you, steal or corrupt your data, or even damage your systems. Unfortunately, firmware exploits are not rare occurrences. Not too long ago, a cybersecurity professional discovered that sending a 33-character text message to a router generated an SMS response that included the administrator username and password.

How do I protect myself?

The best way to defend yourself from firmware exploits is to immediately roll out firmware updates from the device’s manufacturer. With that said, you need to keep in mind that every manufacturer has different procedures for checking and updating firmware. For instance, if you have a D-Link router, typing “192.168.0.1” into a web browser will allow you to access its firmware and update process, assuming you have the username and password. If you’re unfamiliar with your router manufacturer’s procedures, you can type “[manufacturer name] router firmware update” on any search engine like Google.

But remember, routers are just one example of how firmware affects your cybersecurity posture. Hard drives, motherboards, and even mice and keyboards need to be checked as well. We understand this can be extremely tedious, and that’s why we highly recommend hiring an IT provider to take care of it for you.
