HP Adds Security Features To Enterprise Printer Firmware

Earlier this week HP announced that their range of enterprise class LaserJet printers would include security features to better secure them against external attacks.

The printer models that include these features are the following:

  • HP LaserJet Enterprise M506 series
  • HP LaserJet Enterprise MFP M527 series
  • HP Color LaserJet Enterprise MFP M577 series

In addition, printers manufactured since 2011 should be able to benefit from some of the new security enhancements via a HP FutureSmart service pack update.

The security improvements enable the printers to defend against having their BIOS (defined) updated with a maliciously tampered version. In addition, only known good firmware can be executed (allowed to run/function). Moreover the printers feature a runtime intrusion detection system that prevents malware from being loaded into the printer’s memory.

Such printers can also take advantage of HP JetAdvantage Security Manager software that allows the IT administrator to enforce a security policy to allow them to disable unused access protocols (reducing the possibility of external attack), closing networking ports and erasing documents stored within the printers memory/hard disk to maintain confidentiality. When a printer is rebooted, all of the settings specified within the security policy will be enforced returning the printer to a known good and compliant state.

More information on these new printer models is available here and here. A link to the firmware updates for older printer models is provided above.

These security enhancements should enhance an enterprise’s security posture by preventing confidential documents from leaving the organization via networked printers or from malware installed on the printer capturing documents sent for printing or stored in the printer’s hard disk or memory. According to HP they are currently the only printer manufacturer to offer these security features but other manufacturers will likely follow suit. These features will make a worthwhile addition to have if you are considering replacing/upgrading your enterprise printer in the future.

Thank you.
