In addition, it is recommended that users and relevant users improve their network security awareness and security protection capabilities, update and upgrade firmware or service programs in a timely manner, repair vulnerabilities, and standardize security configuration. For servers, computer hosts and smart devices that do not need to provide public Internet services, it is recommended to directly shut down DNS, SSDP, NTP, SNMP, Chargen, Memcached and other services, or block external IP access to these service ports on firewalls or network entrances and exits. For those who need to provide services to designated IP, access control policies such as firewalls can be configured to allow authorized IP access and prohibit other IP access. In addition, some services such as Memcached can also prevent reflection attacks by changing the default service port or changing the transmission protocol type to TCP. For those who need to provide public Internet services, according to the characteristics of reflection attacks, the message traffic of specific reflection attack instructions can be monitored, identified and filtered, and the forged source IP address of reflection attacks can be monitored, identified, limited in speed, limited in flow and intercepted.在海外的一次简易爆炸中幸存下来后，一名骑着军用摩托车的年轻士兵因背部和腿部骨折出院。为了养家糊口，他不顾一切地训练，使自己不可能重新成为一名越野赛车手。刘三顺呆愣半响，才艰涩地回道：泥鳅，爹一直都顺着你的心思，那年也去张家求亲了。　　林秀香饰演莫硕熙，她是MC集团的独生女，兼具智力颜值财力，虽然她表面上是一个旁若无人的财阀女，但其实内心是一个为了查明15年前母亲死因而卧薪尝胆的人物。钢琴系优等生李臻言梦想着成为一名指挥家，但却因童年的阴影一直踟蹰不前。他在人生失意的时候与音乐怪才方小莴相遇，方小莴不受拘束、灵动纯粹的音乐风格，李臻言与她因音乐而产生了更深的羁绊与共鸣，由此慢慢敞开心扉，重燃对梦想的追求。同时，二人在同窗生活中也产生了爱情，成为 彼此的依靠，并在对方的支持和鼓励下直面内心的恐惧，一同踏上追求音乐和梦想的旅途......
