A program running in its own domain is secure because we can design so that only it can access itsdata and no user can run the program (even root) except for those use is allowed by policy. The security policy is very strong and no application can interfere because it is controlled directly from the … Đọc tiếp SELinux with omarine policy: An in-depth look at the security policy – secure program with its own domain: Part 1

All programs are checked for security before running. In more detail, whenever the execve() function (or its front-ends functions) is called to execute a program, the kernel conducts a check of permissions. It does that by using hook functions installed with execve().The execve() function is defined in the fs/exec.c file of the kernel source code. … Đọc tiếp SELinux: kernel: The steps for security checking a program before it runs and the corresponding security rules

Neural network is a modern machine learning method that has been widely adopted. However, random forest, an improvement of the traditional decision tree may be a better choice for some problems because of its simplicity and much lower computational cost. A random forest is an ensemble of decision trees that have a different set of … Đọc tiếp Random forest vs Neural network
