cyber counterintelligence

With the advent of various intelligent cyber-attack tools, it is possible for ordinary technology attackers to attack vulnerable computer network systems in a relatively short period of time. If the security personnel want to win in the cyber War of the invasion, they must first "TSE" to use the corresponding countermeasures to organize these attacks. Current attack tool developers are using more advanced

In the network security world, DDoS attacks are not a new term.

If organizations want to protect their data and avoid embarrassing data intrusions, they need to shift their focus from the network to software security, especially source code and web-based applications. Last night, users and security experts issued such a warning at a cyber-crime symposium here. "We need to start using different tools to fight the enemy," said Ted Schlein, a partner at venture capital company Kleiner Perkins Caufield byers, in a pa
