1 LINUX Security, Firewalls & Proxies

2 Course Title Introduction to LINUX Security Models Objectives To understand the concept of system security To understand the need for secured systems Introduction to Intrusion Detection, Firewalls & Proxies Introductory Course

3 Introductory Course… Training Road Map Understanding the security triangle – confidentiality, integrity & availability Introduction to Linux Security Model Traditional Security Architecture Authentication & access control mechanisms Secure Operating Systems Partitioning and File System Security Security Updates Log Concept Services and Protocols Secure remote administration

4 Introductory Course… Training Road Map… Firewall Introduction TCP/IP Recap iptables (Netfilter) Implementation Management Proxies Simulated Attack

5 Duration 8 hours (6 hours lecture + 2 hours laboratory) Pre-requisites Basic LINUX commands Trainer requirement Good understanding of the LINUX System Advanced LINUX commands System Administration Understanding on Networking concepts, IP addresses, subnets, etc Excellent understanding of security models & their implementation Introductory Course…

6 System requirements Hardware Cluster (independent of the main network) with atleast two server nodes Terminal for each participant Software OS Tools for ethical hacking Firewall Proxy IDS / IPS Introductory Course…

8 Course Title LINUX Security - Intermediate Objectives To understand the concept of system security To understand the need for secured systems To be able to implement Intrusion Detection, Firewalls & Proxies Linux security – Intermediate

9 Training Road Map Understanding the security triangle – confidentiality, integrity & availability Introduction to Linux Security Model Traditional Security Architecture Authentication & access control mechanisms Partitioning and File System Security Security Updates Log Concept Services and Protocols Secure remote administration Linux security – Intermediate

10 Training Road Map… Cryptography Basics SSL and VPN Securing Remote Access into the server Securing Apache Application-Level Gateway Basics IDS and IPS Linux security – Intermediate

11 Training Road Map… Firewall Introduction Need for firewall TCP/IP concept recap TCP/IP model Common protocols - TCP, UDP, IP, ICMP TCP 3 way handshake Linux security – Intermediate

12 Training Road Map… Firewall… Types of firewalls Working principles (at what level / layer does it do the checking) Software / hardware based firewall Packet filtering iptables basic configurations and usage, chains Practical implementations firewall management (using firewall script / ruleset software) GUI based / web based Linux security – Intermediate

13 Training Road Map… Firewall… Further reading/discussion Firewall, why is it not enough Other threats that cannot be detected Firewall, as one of the options, not a means to solve security problems sample of combination with firewall usage IDS ? IPS ? what next? Proxies Linux security – Intermediate

14 Proxies Introduction Configuring Audit and Log Linux security – Intermediate
