What tool can help determine dependencies for a process during a security examination?

The tool that is particularly effective for determining dependencies for a process during a security examination is ldd. This utility is used primarily in Unix-like operating systems to display the shared library dependencies of executable files. When you run ldd on a binary, it reveals which shared libraries the binary requires to execute, providing insight into the other components that may be involved in the process.

Identifying these dependencies can be important in a security context because any vulnerabilities present in these shared libraries could potentially affect the security of the main application. Understanding the complete picture of how an application interacts with its libraries is crucial for assessing security risks, especially when considering potential exploits or unauthorized access.

In contrast, while tools like readelf and objdump can provide detailed information about binary files and can serve certain security analysis purposes, they do not primarily focus on showing the dynamic dependencies of shared libraries. strace, on the other hand, is excellent for tracing system calls made by a process during its execution, but it does not directly show the library dependencies like ldd does. Thus, ldd is the most suitable choice for establishing those critical links to shared libraries during a security examination.
