عنوان دوره: Lynda Protect Your Network with Open-Source Software
سطح: مقدماتی
مدت زمان: 1 ساعت و 49 دقیقه
نویسنده: Jungwoo Ryoo


Network protection is vital to organizations big and small, but it doesn't have to be an expensive proposition. Learn how to protect your network with open-source tools, and do it completely FREE. Jungwoo Ryoo shows how to set up firewalls, investigate network traffic with a packet analyzer, detect threats and malicious activity with an intrusion-detection system, and enable network logging and monitoring. Start here for a low-cost route to a more secure network.
Topics include:
Setting up a host firewall
Setting up a host as a network firewall
Setting up a DMZ
Capturing and analyzing packets with Wireshark
Using Snort to detect network intrusions
Logging network activity with syslog-ng, Kiwi, and other solutions
Setting up a simple network management protocol (SNMP)
