http://danscourses.com - Learn how to create an IPsec VPN tunnel on Cisco routers using the Cisco IOS CLI. CCNA security topic. 1. Starting configurations for R1, ISP, and R3. Paste to global config mode : hostname R1 interface g0/1 ip address 192.168.1.1 255.255.255.0 no shut interface g0/0 ip address 184.108.40.206 255.255.255.0 no shut exit ip route 0.0.0.0 0.0.0.0 220.127.116.11 hostname ISP interface g0/1 ip address 18.104.22.168 255.255.255.0 no shut interface g0/0 ip address 22.214.171.124 255.255.255.0 no shut exit hostname R3 interface g0/1 ip address 192.168.3.1 255.255.255.0 no shut interface g0/0 ip address 126.96.36.199 255.255.255.0 no shut exit ip route 0.0.0.0 0.0.0.0 188.8.131.52 2. Make sure routers have the security license enabled: license boot module c1900 technology-package securityk9 3.

http://www.soundtraining.net Author, speaker, and IT trainer Don R. Crawley demonstrates how to configure a site-to-site VPN between two Cisco ASA security appliances. The demo is based on software version 8.3(1) and uses IPSec, ISAKMP, tunnel-groups, Diffie-Hellman groups, and an access-list. The demo is based on the popular book "The Accidental Administrator: Cisco ASA Security Appliance: Step-by-Step Configuration Guide (http://amzn.com/1449596622) and includes a link where you can download a free copy of the configs and the network diagram.

The National Security Agency (NSA) is a national-level intelligence agency of the United States Department of Defense, under the authority of the Director of National Intelligence. The NSA is responsible for global monitoring, collection, and processing of information and data for foreign intelligence and counterintelligence purposes, specializing in a discipline known as signals intelligence (SIGINT). The NSA is also tasked with the protection of U.S. communications networks and information systems. The NSA relies on a variety of measures to accomplish its mission, the majority of which are clandestine.Originating as a unit to decipher coded communications in World War II, it was officially formed as the NSA by President Harry S. Truman in 1952. Since then, it has become the largest of the U.S. intelligence organizations in terms of personnel and budget. The NSA currently conducts worldwide mass data collection and has been known to physically bug electronic systems as one method to this end. The NSA has also been alleged to have been behind such attack software as Stuxnet, which severely damaged Iran's nuclear program. The NSA, alongside the Central Intelligence Agency (CIA), maintains a physical presence in many countries across the globe; the CIA/NSA joint Special Collection Service (a highly classified intelligence team) inserts eavesdropping devices in high value targets (such as Presidential palaces or embassies). SCS collection tactics allegedly encompass "close surveillance, burglary, wiretapping, [and] breaking and entering".Unlike the CIA and the Defense Intelligence Agency (DIA), both of which specialize primarily in foreign human espionage, the NSA does not publicly conduct human-source intelligence gathering. The NSA is entrusted with providing assistance to, and the coordination of, SIGINT elements for other government organizations - which are prevented by law from engaging in such activities on their own. As part of these responsibilities, the agency has a co-located organization called the Central Security Service (CSS), which facilitates cooperation between the NSA and other U.S. defense cryptanalysis components. To further ensure streamlined communication between the signals intelligence community divisions, the NSA Director simultaneously serves as the Commander of the United States Cyber Command and as Chief of the Central Security Service. The NSA's actions have been a matter of political controversy on several occasions, including its spying on anti-Vietnam-war leaders and the agency's participation in economic espionage. In 2013, the NSA had many of its secret surveillance programs revealed to the public by Edward Snowden, a former NSA contractor. According to the leaked documents, the NSA intercepts and stores the communications of over a billion people worldwide, including United States citizens. The documents also revealed the NSA tracks hundreds of millions of people's movements using cellphones metadata. Internationally, research has pointed to the NSA's ability to surveil the domestic Internet traffic of foreign countries through "boomerang routing".
