Security related to Canon products
With the popularisation of the Internet and wireless LAN technology, a diverse range of electronic devices are now capable of connecting to a network, enabling the remote operation of various functions.
By connecting to a network, information devices can become vulnerable to unauthorised third-party access, which could lead to such security issues as unauthorised usage of the device.
To minimise the likelihood of such issues, devices must make use of proper settings and be used in a secure environment.
To help ensure that our customers can use Canon products with peace of mind, we recommend that users implement the following security measures -
1. Create an administrator ID and password
In order to strengthen the security of your Canon product, please create an administrator ID and password. Administrators can limit access to a multifunction printer and control which functions are made available to individual users. This helps to prevent unauthorised access to the device and protects data held in the machine’s configuration.
2. Use a private IP address
When setting up your printer, assign a private(internal) IP address. This gives you more control over access to the device than assigning a public(external) IP address which may permit unauthorised access over the internet to the device and it’s functions.
3. Configure a firewall (using a router etc)
When installing your Canon product on an internal/home network check your router/firewall set up to ensure that the device is not visible from the internet (unless this is your intention). If this is a physical connection check the cable is plugged into an internal port. If this is on a corporate network you may need to contact your network administrator for guidance.
4. Encrypt communications
If your Canon device is capable of supporting encryption we recommend that this is enabled to ensure communication between your device and the printer remains secure. This would mean that you are communication with the devices using https or equivalent.
Security measures for specific Canon products
We are aware of news articles regarding research from University Alliance Ruhr concerning potential vulnerability for networked printers via the PostScript programming language used widely across our industry. No Canon devices were tested in the research.
Canon works constantly to ensure the highest level of security in all of our products and solutions, including networked printers. We take the security of our customer’s information seriously and its protection is our utmost priority. Our MFD Hardening Guide, explains and advises on the best configuration settings for secure implementation.
Information regarding security measures for specific Canon products and their set-up procedures are outlined below. Please note, the information is only available in English –
Spectre and Meltdown CPU Security Vulnerabilities
Vulnerabilities were recently made public regarding certain CPUs from Intel, AMD and ARM that make use of speculative execution to improve their performance. These vulnerabilities may allow an attacker to gain unauthorised access to areas of private cached memory.
Two variants of the vulnerabilities that use different techniques to exploit the speculative execution functions within the affected CPUs were identified and named. They are CVE-2017-5715, CVE-2017-5753: “Spectre” and CVE-2017-5754: “Meltdown”.
The following Canon external controller products may be impacted by the vulnerabilities. Though there is currently no known way to exploit these vulnerabilities, countermeasures are being prepared so that customers can continue to use our products without concern.

The following Canon service may be impacted by the vulnerabilities. Though there is currently no known way to exploit these vulnerabilities, countermeasures were put in place by end of February 2018.
All Canon laser multifunction printers and Canon laser printers and their related software products, except the above-mentioned, are not affected by these vulnerabilities through any known exploitation process. Customers can continue using our products reliably.
Canon is constantly working to ensure the highest level of security is reached in all our products and solutions. We take the security of our customer information seriously and its protection is our utmost priority.
Vulnerability in WPA2 Wi-Fi Encryption Protocol
Recently, a researcher made public a vulnerability known as KRACKs in the standard wireless LAN (Wi-Fi) encryption protocol WPA2. This vulnerability allows an attacker to intentionally intercept the wireless transmission between the client (terminal equipped with Wi-Fi functionality) and the access point (the router etc.) to perform potentially malicious activity. For that reason, this vulnerability cannot be exploited by anyone outside the range of the Wi-Fi signal or by anyone in a remote location using the internet as an intermediary.
We have yet to confirm that any issues have been encountered by users of Canon products as a result of this vulnerability, however, in order to allow customers to continue using our products with peace of mind, we recommend the following preventative measures:
•Use a USB cable or Ethernet cable to directly connect compatible devices to a network
•Encrypt data transmission from devices that enable encryption settings (TLS/IPSec)
•Use such physical media as SD cards with compatible devices
•Use such settings as Wireless Direct and Direct Connect with compatible devices
As the operation procedures and functions offered vary from device to device, please consult your device’s manual for more details. We also recommend you take appropriate measures for such devices as your PC or smartphone. For information on the appropriate measures for each device, please contact the device’s manufacturer.

Fraudulent Store WarningIt has come to our attention that there are several websites claiming to offer significantly discounted Canon products at 90% off or more. These websites are designed to look like our official Canon Store and we believe they are not legitimate, aimed only at confusing and deceiving our customers into sharing personal and financial data. We advise our customers to be vigilant when shopping online with Canon and other retailers.
To recognise the official Canon online store, all Canon stores across Europe have a similar domain name: https://store.canon.xx
The final characters change per each country. For example: https://store.canon.fr & https://store.canon.co.uk.
