Are SD Cards a Security Threat for Businesses?

SD and microSD cards provide flash memory storage for things like digital cameras, smartphones, and tablets. And as with anything used to store important data on a mobile device, there’s concern about how easy they are to hack, or worse to corrupt with malware. But according to Samuel Bucholtz, cofounder of Casaba, a security analysis consulting firm, flash memory storage isĀ “much more useful for targeted attacks against an individual or a company than a broad attack against consumers,” Other experts agree, but that statement doesn’t exactly let business leaders rest easy. However, Bucholtz went on to say thatĀ “In most cases the data can only be harvested if the SD card is physically retrieved afterwards or it is connected to a previously compromised system.”

Ok. Whew. But what are some ways that you can safeguard your mobile storage or SD card from these and other kinds of attacks. Here’s what the Ripple IT Support Team recommends:

Turn off your Bluetooth when not in use

It’s a good idea to keep the Bluetooth off unless you’re using it to connect to something like your car or printer. Some hackers are adept at breaking into devices via the Bluetooth connection. And remember, unless you recognize the Bluetooth device don’t connect to it or accept any unknown files out of curiosity. Better safe than sorry.

Don’t leave your data lying around

 

If your have SD, microSD, or any kind of removable flash storage it’s best to make sure it stays in your device, and that your device stay on you when you’re out. It may not be a huge risk for most of us, but there have been instances of hackers loading malicious programs on cards left unattended.

Backup to the Cloud

 

Most smartphones allow you to backup your data and contact lists to the cloud for easy recovery should something happen to your device. Here’s some info on how it’s done: Backup and Restore an iPhone | Backup an Android device to Google Cloud

Replace old SD cards

 

Though not necessarily a security threat, losing your data to a corrupted card can be a big letdown. Flash storage like SD and microSD cards are notoriously unreliable, and they degrade over time with each use. So make sure all your important data is kept on relatively new cards.

That’s all, folks! Sure, there’s plenty more security measures out there but these four few tips should serve you and your data pretty well.
