Description
Welcome to this course. Nowadays, system security has gained a lot of momentum and software professionals are focusing heavily on it. Linux is often treated as a highly secure operating system. With the growing popularity of Linux, more and more administrators have started moving to the system to create networks or servers for any task. However, the reality is that Linux has its share of security flaws, and these security flaws allow attackers to get into your system and modify or even destroy your important data. But there’s no need to panic, since there are various mechanisms by which these flaws can be removed, and this course will help you learn about different types of Linux security to create a more secure Linux system.With lots of step-by-step recipes, the course starts by introducing you to various threats to Linux systems. You then get to walk through customizing the Linux kernel and securing local files. Next you will move on to manage user authentication locally and remotely and also mitigate network attacks. Finally, you will learn to patch bash vulnerability and monitor system logs for security.In this course, you'll learn:Understanding Linux Security ProblemConfiguring a Secure and Optimized KernelLearning various vulnerabilities and exploits in relation to Linux systemsLocal Filesystem SecurityLocal Authentication in LinuxConfigure and build a secure kernel and test itLearn about file permissions and security and how to securely modify filesExplore various ways to authenticate local users while monitoring their activities.Remote AuthenticationNetwork SecuritySecurity ToolsLinux Security DistrosBash Vulnerability PatchingSecurity Monitoring and LoggingAuthenticate users remotely and securely copy files on remote systemsReview various network security methods including firewalls using iptables and TCP WrapperUnderstanding Linux Service SecurityScanning & Auditing LinuxExplore various security tools including Port Sentry, Squid Proxy, Shorewall, and many moreUnderstand Bash vulnerability/security and patch managementVulnerability Scanning & Intrusion Detection
