Cyber Security: CTU Threat Intelligence Services
The Dell SecureWorks Counter Threat UnitSM (CTUSM) research team is a distinguished group of security researchers and experts who analyze data from across thousands of global networks, comb the cyber underground for intelligence and leverage relationships throughout the security community to identify emerging threats, develop countermeasures against new malware and exploits, and protect our customers.
For Dell SecureWorks, research represents the nucleus of our company and operations. Research is breaking down and reverse engineering malware to understand what makes it tick. Research is seeing how disparate events are connected. Research is determining how an exploit is communicating with its Command and Control. Research is identifying who is behind the threat. Research is infused into our managed security services and security consulting practices.
This is why we hire only the best and brightest security researchers from private industry, military and intelligence communities – Researchers with proven track records and first-hand technical experience dealing with cyber threats and protecting some of the most sensitive public and private systems and data resources in the world.
The Dell SecureWorks Counter Threat Unit research team’s work underpins the success of our Managed Security Services and Security Operations Centers, and is shared widely with our security consulting teams. In addition, our researchers share pertinent information with our customers and the public at large. Their primary role is understanding the nature of threats our customers face, and creating strategies and countermeasures to address those threats and protect our customers.
Being a sysadmin has its share of joys, however, challenges abound in this digital world!
Thursday, April 24, 2014: A sysadmin is entrusted to constantly monitor the system. Sysadmins have to be aware of everything about the system starting from CPU load and network traffic statistics to how much free disk space is available. In addition, things go haywire from time to time, in which case it is better that the sysadmin finds out from the monitoring system than from an user. The following tools come in handy when such a case arrives.
