PROTOCOL-FTP -- Snort alerted on suspicious use of the FTP protocol. FTP is generally unsafe, as it sends all data in plain text, including passwords. Stolen data may also aggregate via FTP, and malware-infected items are often made available via FTP sharing sites. Malicious FTP attempts are common, such as directory traversal, overflow attempts, FTP probing (for instance, from the SATAN tool), etc.
