The Federal Trade Commission’s practice of going after companies for lax data security after they suffer a breach may be entering a new phase:  companies are starting to fight back.  LabMD, an Atlanta-based medical testing lab, has challenged the FTC’s authority to bring an enforcement action over the company’s allegedly poor data security practices.  Although most companies settle FTC enforcement actions, Wyndham Hotels may have started a trend last year when it moved to dismiss a similar FTC complaint in federal court.  Although that case is pending (in a district court in New Jersey), it may have put some “wynd” in the sails of companies that are not willing to lower the flag in the face of threatened action by the Commission.
