Firmware updates: A vital aspect of business security

In the race against cyberthreats, every update matters. This includes the often neglected firmware updates. This article sheds light on why updating your firmware is an essential step in securing your business.

What does firmware do?

Before we dive into the significance of firmware updates, it’s crucial to understand what firmware is and its role in the overall functionality of devices. Firmware is a specialized type of software embedded within the hardware of electronic devices. Unlike regular software that runs on an operating system, firmware is designed to control the device’s specific hardware components.

Firmware acts as the bridge between a device’s hardware and software, allowing them to work together seamlessly. It is commonly found in a variety of devices, including routers, printers, security cameras, and other Internet of Things (IoT) devices.

Why is it crucial to upgrade firmware?

There are several reasons why keeping firmware up to date is crucial, such as:

  • Security vulnerabilities – Over time, security vulnerabilities are discovered in firmware that could potentially be exploited by cybercriminals. Firmware updates often include patches to address these vulnerabilities, protecting your devices from unauthorized access and data breaches.
  • Enhanced performance – Firmware updates not only address security concerns but also include improvements to the overall performance and stability of the device. This can lead to a more efficient operation and an extended life span for your hardware.
  • Compatibility – As technology evolves, so do the software and applications that interact with your devices. Firmware updates ensure that your hardware remains compatible with the latest software, reducing the risk of compatibility issues that could compromise your business operations.
  • Feature enhancements – Manufacturers frequently release firmware updates to introduce new features or enhance existing ones. Staying up to date ensures that your devices can take advantage of the latest capabilities, providing your business with a competitive edge.

What is the best way to install firmware updates?

While firmware updates are essential, improper installation can lead to issues or even device malfunctions. Here are some best practices for installing firmware updates:

  • Regular monitoring – Stay informed about firmware updates for all your devices. Most manufacturers provide release notes that detail the changes and improvements. Regularly check for updates and prioritize those addressing security vulnerabilities.
  • Back up before updating – Before initiating any firmware update, make sure to back up critical data. While rare, there is a slight risk that the update process could cause data loss or other unforeseen issues.
  • Follow manufacturer instructions – Each device manufacturer may have specific instructions for updating firmware. Always follow the recommended procedures outlined in the user manual or on the manufacturer’s website.
  • Schedule downtime – Plan firmware updates during non-business hours to minimize disruption to your operations. If the update requires device reboots, schedule it when there’s the least impact on your business.
  • Test updates before deployment – Consider testing the firmware update on a noncritical device first. This will give you an opportunity to identify and address any potential issues before deploying the update to all devices.

By understanding the role of firmware, recognizing the importance of timely updates, and adopting best practices for installation, you can ensure that your business remains secure and operates efficiently. Keeping firmware up to date is not just a precautionary measure; it’s a proactive step toward safeguarding your business in the ever-changing threat landscape.

What is firmware and why is it important?

Securing your small business is a never-ending battle, but there are some steps you can take to make it a little bit easier. One of those steps is making sure your firmware is up to date. But what is firmware and why is it crucial to update it regularly? Read on to learn more.

What does firmware do?

Firmware is a type of software that is stored on read-only memory (ROM) chips. It is used to control the hardware of a device, such as a computer, and is typically permanently programmed into the ROM. Firmware is different from other types of software, such as application software and operating system software, as it is designed to work with specific hardware components and cannot be easily transferred to another device.

Firmware typically contains instructions for how the hardware should interact with the rest of the system, as well as low-level routines for tasks such as booting up the device or managing memory. While firmware can be updated, it is usually more difficult than updating other types of software, and in some cases may require special equipment or knowledge. As a result, firmware updates are often reserved for fixing critical bugs or adding new features to the hardware.

Why is it crucial to upgrade firmware?

Microsoft’s 2021 Security Signals report warns that firmware attacks are increasing. These types of attacks force malware onto computer systems in order to disrupt the firmware on motherboards or hardware drivers. They can use such malware to remotely control the infected devices, extract data, and even block users from their devices and systems.

Updating your business devices’ firmware ensures that everyone is using the most recent version of the firmware. This can help prevent data breaches, as well as keep your devices running smoothly. In addition, updating firmware can help improve compatibility with other devices and software, as well as provide new features and bug fixes. In this way, updated firmware protects your business and maintains peak device performance.

What is the best way to install firmware updates?

The procedure for upgrading firmware varies from device to device. On iOS and Android devices, you may simply download and install firmware upgrades. However, devices such as routers will require firmware updates that can only be accessed from the manufacturer’s website or administrative console.

Updating the firmware may be time-consuming and laborious. Firmware updates might cause your devices to be reset, resulting in lost customizations on your computers, routers, and other devices. Additionally, you could also risk damaging your equipment if you do not follow the manufacturer’s instructions to the letter.

Firmware updates are an important part of keeping your business secure, and it’s something that you should be doing on a regular basis. This task can be daunting, but it’s a crucial step that should not be ignored. If you need help getting started, contact us today. Our IT experts are here to guide you.

The importance of updating firmware

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.

Keep security threats out of your Mac

The hearsay that Macs cannot be infected by viruses or malware couldn’t be further from the truth. There are plenty of cyberthreats that pose risks to Macs, so if you’re a Mac user, you should prioritize your device’s security. The good news is that protecting your Mac is simple and easy. Just follow these steps.

Check your privacy settings

Make sure that your Mac settings are set up properly to keep your data safe. Manage the information your Mac makes available across the internet or on a network by going to Apple menu > System Preferences > Security & Privacy > Privacy. From there, you can choose which information to share and with whom. For example, you can specify which apps are allowed to see personal information, such as your location, contacts, photos, or music.

Take advantage of the firewall

A firewall protects your Mac from unwanted contact initiated by other computers on a network or the internet. It protects your computer by allowing only authorized services and apps to communicate with your Mac, so be sure to enable macOS’s built-in firewall.

To do so, just go to Apple menu > System Preferences > Security & Privacy > Privacy then, click Firewall. If the padlock icon at the bottom left is locked, click it and key in your username and password. Enable the firewall by clicking Turn On Firewall.

To modify Firewall settings, click on Firewall Options… just below the “Turn Off Firewall” button. You will find a list of services and apps that are allowed to receive inbound connections. If you want to add an app or service to the list, just click the “+” button below the list itself. However, we recommend keeping this list as short as possible, as the apps listed can be exploited by cybercriminals.

Another useful feature to enable is stealth mode. This option will make your Mac more difficult to find, thus keeping hackers and malware at bay. For instance, if you are in a coffee shop and connected to its unsecured Wi-Fi, enabling stealth mode will make your Mac invisible on that public network. To turn on this feature, just tick the box next to “Enable stealth mode” in Firewall Options. A dialog box will pop up, and you can click on the “Enable Stealth Mode” button.

Set up a firmware password

Every new Mac today has the FileVault encryption automatically enabled. This means that your device already encrypts the hard drive by default, and the only way your data can be accessed is by logging in. Keep in mind, though, that this feature won’t necessarily save your account in case someone reinstalls the operating system or uses a memory stick to boot the Mac and remove all data from your hard disk.

To increase protection, set up a firmware password. Do this by restarting your computer, then pressing and holding down Cmd+R before the Apple logo shows up on the screen. You can let go of the keys once the progress bar pops up.

When the utilities window appears, click on Utilities in the menu bar, then choose Startup Security Utility or Firmware Password Utility. Click on Turn On Firmware Password… and simply follow the succeeding instructions.

Finally, quit the utilities window, then choose Apple menu > Restart. Make sure to never forget or misplace your firmware password, because only Apple technicians can recover it.

Ensure that your confidential data remains private by performing minor tweaks on your Mac’s system settings. It takes only a few minutes to ensure lasting online protection. If setting up a firewall or firmware password sounds a little too advanced for you, or if you need to set up more advanced defenses, don’t hesitate to get in touch with our experts.

Obsolete firmware poses security risks

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.
