A “real live security professional” knows that they have to protect information in all of its forms. They know that laptops frequently outnumber desktops. They know that they have to secure mobile workforces. They know that there are frequently computer monitors in public spaces, where you want to limit the observability of information available on computer screens, not withstanding medical offices, security desks, any computer with personally identifiable information, etc.
While this article is not intended as endorsement for 3M privacy filters, these serve a critical role in securing corporate information. I began writing this article to stress that shoulder surfing was a critical physical security concern that security programs should address with a combination of increased awareness about the concern, as well as with other protections, such as 3M privacy filters. I grew more horrified by the lack of security awareness the more I read.
And for the record, training your users to yell, “teacher, he’s cheating off me,” is not enough. Users need to know that shoulder surfing is a serious concern, and companies need to also take other precautions, like investing in privacy filters, to secure users further. Awareness needs to be proactive, as should the other countermeasures you put in place.
