The nmap command (short for network mapper) is a network exploration/security auditing tool that can rapidly scan networks to help you find out what hosts are available. With nmap, you can discover open ports and services, and even find out what operating systems are on your network. I've used nmap to find out what machines are on a network and what ports/services are open. If I find a port that shouldn't be open, I can close it to avoid security issues.

DDoS detection tool FastNetMon detected a DDoS attack of 1.5 billion packets per second. The target: a European provider of DDoS scrubbing services. The attack is one of the largest DDoS attacks ever, but still falls far short of the 11.5 billion packets recently detected by Cloudflare. The choice of target is striking in any case: the DDoS attack was aimed at a service that protects other organizations against the consequences of such a "packet flood."

Davis Lu, 55, was convicted of installing a "kill switch" on the network of his former employer by planting malicious code designed to crash its servers in the event that he was fired. The kill switch was activated when the company terminated Lu's employment and deactivated his credentials, causing the kill switch, "IsDLEnabledinAD" - referring to whether Lu's account was still active in the company's Active Directory. The incident locked out thousands of employees from accessing the company's systems.
