In this tutorial you’ll learn how Suricata signatures are structured, and some important options that are commonly used in most rules. Once you are familiar with how to understand the structure and fields in a signature, you’ll be able to write your own signatures that you can combine with a firewall to alert you about most suspicious traffic to your servers, without needing to use other external rulesets.
Secured Socket Layer (SSL) is the cryptography protocol to provide message security over the internet. It works on the notion of Private and Public keys and messages are encrypted before sending it over the network. To configure SSL on Tomcat, we need a digital certificate that can be created using Java keytool for development environment. For production environment, you should get the digital certificate from SSL certificate providers, for example, Verisign or Entrust.
In this tutorial you will create a Let’s Encrypt wildcard certificate. Wildcard certificates are SSL certificates that can secure any number of subdomains with a single certificate. You may want one of these if you need to support multiple subdomains without configuring them individually.
Earlier I wrote a program to connect to remote database on SSH server. Today I am presenting a program that can be used to connect to SSH enabled server and execute shell commands. I am using JSch to connect to remote ssh server from java program.
Version control software (VCS) is an essential part of most modern software development practices. Among other benefits, software like Git, Mercurial, Bazaar, Perforce, CVS, and Subversion allow developers to save snapshots of their project history to enable better…
A Content Security Policy (CSP) is a mechanism for web developers to increase the security of their websites. By setting a Content Security Policy, web developers can instruct web browsers to only load resources from certain trusted domains, enforce secure HTTPS connections, and even report policy violations as they occur. This can prevent many content injection and cross-site scripting (XSS) vulnerabilities, which often lead to data leaks, website vandalism, and malware distribution.
