The log entries show repeated attempts to access directories using patterns such as ../, which is a common directory traversal attack technique. Directory traversal (or path traversal) aims to access files and directories outside the web server's root directory by manipulating file paths. The ../ sequence is used to move up one directory level, which attackers exploit to try and retrieve sensitive files.
