Listed below are the few ways Linux Server can be secured

1. Group policies: This is a way to ensure security by applying group policies and permissions both on the group level and the files level. Through proper permission configuration we can easily restrict other users from accessing those files and directories.

2. Implementation of the firewall: Implementing firewall in each of the Linux server will definitely help in securing your machine from outside threats. Iptables will help in filtering the network traffic that are entering into the system and even going out of the system.

3.Enabling SELINUX: Enabling SELINUX is another way to secure your system especially a Linux Server. Selinux is a powerful security that checks and allows applications to run into the system. It won't allow any untrusted application to run into the system.

Troubleshooting

Explanation:

These actions are called troubleshooting.

Troubleshooting is used to diagnose the unexpected error while you are performing some action on the computer. For example

You are running skype, and a one-day mic or sound performing unexpected error. What will you do? You have to perform the troubleshooting for MIC and sound to diagnose the problem.

During troubleshooting, you will wizard through steps of the procedure to diagnose the problem step by step. If the problem will be identified, the solution will be suggested.

You may experience sometimes your Wifi router at home not working. For this to identify the unexpected error you will perform the troubleshooting.

In short, troubleshooting is used to diagnose unexpected error while performing some action on the computer. If troubleshooting does not work, then close all the programs running on your machine, then shut down your computer. Wait a couple of minutes, and then start your computer and see, the problem may have been alleviated.

Lasso: R example

To run Lasso Regression you can re-use the glmnet() function, but with the alpha parameter set to 1.

# Perform 10-fold cross-validation to select lambda --------------------------- lambdas_to_try <- 10^seq(-3, 5, length.out = 100) # Setting alpha = 1 implements lasso regression lasso_cv <- cv.glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = TRUE, nfolds = 10) # Plot cross-validation results plot(lasso_cv)

Best cross-validated lambda lambda_cv <- lasso_cv$lambda.min # Fit final model, get its sum of squared residuals and multiple R-squared model_cv <- glmnet(X, y, alpha = 1, lambda = lambda_cv, standardize = TRUE) y_hat_cv <- predict(model_cv, X) ssr_cv <- t(y - y_hat_cv) %*% (y - y_hat_cv) rsq_lasso_cv <- cor(y, y_hat_cv)^2 # See how increasing lambda shrinks the coefficients -------------------------- # Each line shows coefficients for one variables, for different lambdas. # The higher the lambda, the more the coefficients are shrinked towards zero. res <- glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = FALSE) plot(res, xvar = "lambda") legend("bottomright", lwd = 1, col = 1:6, legend = colnames(X), cex = .7)
