Facebook has teamed with McAfee to run virus scans on content shared across the platform. It is not the only option. Websense has rolled out Defensio, a third-party Facebook app that scans wall posts and messages for malware, phishing links, and spam.
The security push arrives on top of a much bigger issue: Facebook's newly relaxed default privacy settings. More content is now visible to more people by default. That widens the surface area for malicious links, viruses, and social-engineering attacks moving through the network.
McAfee's integration is a Facebook-imposed default. If a user is flagged for compromise, McAfee scans their machine before they can return to the platform. That is a heavy-handed intervention — and a rational one, given the scale of the abuse vector.
The third-party layer is different. Apps like Defensio are marketed directly to individual users, not imposed by Facebook. That raises its own concern: a security app itself becomes an access point. If the vetting is weak, the cure looks a lot like the disease.
What This Signals
Three things.
Privacy control is becoming a consumer product. As Facebook makes information more public by default and more of it surfaces in search engines, demand for tools that give users granular control over what they share, and with whom, is going to grow.
The platform is now the operating system. Users are storing more photos, messages, and personal data on Facebook than on their own hard drives. The platform has to be protected accordingly.
The default settings are the whole game. Most users never touch their privacy controls. Whatever Facebook sets as the default is, in effect, the policy. Every widening of that default expands the attack surface.
Websense's Defensio addresses a real gap. It will not be the last product to try. Expect the security-app category on Facebook to expand quickly, and expect Facebook itself to keep tightening — or being forced to tighten — the underlying platform.
