Logic bombs are difficult to identify and can cause significant damage. In this video, you’ll learn about logic bombs and how some real-world logic bombs caused problems for organizations. << Previous Video: Insider Threats Next: Rogue Access Points >> A logic bomb is a very specific kind of malware that’s waiting for an event to […]

Your network must be secured from both outside and inside threats. In this video, you’ll learn more about insider threats. << Previous Video: Social Engineering Next: Logic Bombs >> One of the reasons that insider threats are such a significant security concern is that our users have a lot of access to the resources that

Social engineering attacks sneak around your electronic defenses and attack users directly. In this video, you’ll learn about the principles of social engineering attacks. << Previous Video: Denial of Service Next: Insider Threats >> Social engineering is a very low-tech form of a security attack. In fact, it doesn’t involve any technology at all. It

Protecting against denial of service attacks is an ongoing security challenge. In this video, you’ll learn about DoS, DDoS, and DDoS amplification attacks. << Previous Video: Wireless Authentication and Security Next: Social Engineering >> A denial of service is when the bad guys are taking a service that’s normally available, and they’re now making it

To gain access to a wireless network, you’ll need to provide some form of authentication. In this video, you’ll learn about authentication and security technologies for wireless networks. << Previous Video: Wireless Encryption Next: Denial of Service >> In a previous video, we discussed encryption mechanisms that we use on our networks. But we also

We rely on encryption to keep our wireless networks secure. In this video, you’ll learn about encryption technologies used with WPA and WPA2. << Previous Video: Access Control Next: Wireless Authentication and Security >> Many of our networking devices these days are using wireless to communicate, and of course, this wireless communication is going through
