For autonomous Vehicles (AV), to operate in a truly autonomous way in future intelligent transportation systems, it must be able to handle the data collected through a large number of sensors and communication links. This is essential to reduce the likelihood of vehicle collisions and to improve traffic flow on the road. However, this dependence on

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

Recommendation: You can add the bundled address 127.0.0.1 directive to the MySQL server configuration to enhance this functionality, forcing MySQL to bundle the local machine's IP address to ensure that only users in the same system can connect to MySQL. Actively monitor MySQL access record MySQL contains a number of different log

shortcomings of the cloud host Some customers are concerned about the security of cloud hosts and feel a lack of control over services. Because the cloud host only provides the network interface, so the customer's data must all obey the cloud service company's arrangement, completely under the latter control. The confidentiality of data is dependent on the latter's professional ethics and protection capabilities. However, this is actually a "pseudo problem" because, in most cases, cloud serv
