Quote:The U.S. National Security Agency is offering advice to security teams looking for wireless best practices to protect corporate networks and personal devices. The recommendations, while pedestrian in scope, do offer system administrators a solid cheat sheet to share with their work-from-home crowd and mobile workforces.
 
For starters the NSA, in a public service announcement posted on Thursday (PDF), urged security teams to be mindful of the wireless threats employees face when using Wi-Fi networks. It also lumps Bluetooth technology and Near Field Communications (NFC) into its list of worrisome protocols.
 
By now, café-based workers have likely mastered both public bathroom and Wi-Fi hotspot hygiene. But, for anyone who hasn’t the NSA advises: “Data sent over public Wi-Fi—especially open public Wi-Fi that does not require a password to access— is vulnerable to theft or manipulation.”
 
Advice also includes warnings of fake access points that can vacuum up user credentials and skim other personal data retrieved on the “evil twin” access points.
