Report: FTP protocol security gaps expose millions of systems

SCM feed for Latest

A recent report indicates that approximately half of the 6 million internet-connected systems using the outdated File Transfer Protocol (FTP) are not secured with encryption. This lack of encryption makes these systems particularly vulnerable to cyberattacks, as attackers can easily intercept sensitive data during file transfers. The findings, reported by SecurityWeek, raise concerns for organizations relying on FTP for data transfer, as they may unwittingly expose critical information to cybercriminals. Given the prevalence of FTP usage, the implications of these security gaps could be widespread, impacting various industries. Companies should prioritize upgrading to more secure file transfer methods to protect their data from potential breaches.
