课程名称：保护Linux系统 概述：本课程探讨Linux操作系统的安全性，非常适合准备Linux基金会认证IT助理（LFCA）考试的人员或对Linux知识感兴趣的学习者。该课程是一个系列课程中的第三门，旨在为信息技术专业人员的工作做好准备。在本课程中，您将学习所有权、身份验证和授权。我们将深入讨论通过备份和冗余来创建安全性，最后探讨如何保护我们网络和系统的边界。 大纲： 1. **所有权与权限** - 描述：本模块探讨Linux操作系统的安全性。我们将首先对文件和目录应用权限，然后研究访问控制列表（ACL）在Linux中的应用，探讨基于上下文的安全控制，最后思考账户类型与权限提升的问题。 2. **管理访问与身份验证** - 描述：本模块聚焦于提高Linux安全性的方法。我们将首先了解Linux可插拔身份验证模块（PAM），这是一套允许系统管理员配置用户身份验证方法的库。接着，我们将研究公钥基础设施（PKI）及其在安全外壳（SSH）中的应用，并利用开放虚拟私人网络（VPN）进行总结。 3. **日志记录与备份** - 描述：本模块将研究本地和远程系统日志记录，并探讨系统文件的备份与压缩，以便在系统事件发生时进行恢复。最后，我们将深入研究Linux中用于归档和恢复的不同工具。 4. **Linux防火墙** - 描述：本模块探讨网络边界和您的Linux主机系统的安全性。我们将研究不同的Linux防火墙技术及其访问控制规则的实施，然后思考在允许交通通过防火墙转发数据包时的处理，最后讨论Linux中的入侵检测系统。 本课程将帮助您更好地理解和应用Linux系统的安全策略，适合希望在IT领域增强自身竞争力的学习者。
Name:Ownership and Permissions
Description:In this module, we look at security and the Linux operating system. We will start by applying permissions to files and directories. We then look at Access Control Lists (ACL) and how they are applied in Linux. We will explore Context-Based security controls. Lastly, we will think about account types and privilege escalation.
Name:Administer Access and Authentication
Description:In this module, we look at ways to increase our Linux Security. We start by looking at Linux Pluggable Authentication Modules (PAM). PAM is a suite of libraries that allows a Linux system administrator to configure methods to authenticate users. We then look at Public Key Infrastructure (PKI) and its use in Secure Shell (SSH). We conclude by utilizing open Virtual Private Networks (VPN).
Name:Logging & Backups
Description:In this module, we look at both local and remote system logging. We will also look at backup and compression of the files on the system to allow recovery in response to a system incident. We will conclude with a deep dive of the different tools available in Linux for archive and restore.
Name:Linux Firewalls
Description:In this module, we look at the security at the boundaries of your network and your host Linux system. We look at different Linux Firewall technologies and the implementation of access control rules in the firewalls. We then think about forwarding packets when we want to allow traffic through the firewall to another host machine. We conclude by looking at intrusion detection systems in Linux.
In this course, we look at security and the Linux operating system. The course material is a good for anyone preparing for the Linux Foundation Certified IT Associate (LFCA) exam or just interested in learning more about Linux. This course is the third course in a series that aims to prepare you for working as an information technology professional. In this course, you will be introduced to ownership, authentication, and authorization. We will drill into creating security through backups and redundancy. We concluded by looking at how to secure the perimeter of our network and systems.
