近年来,随着科学技术的发展,光纤通信网络窃听方法越来越多,技术越来越高明,光纤通信的安全性受到极大的威胁。并且,如今有很多窃听技术极为隐蔽,很难被检测到。因此,相关部门及工作人员应着力研究光纤通信窃听技术以及防御方法,改善光纤通信网络窃听问题。 In recent years, with the development of science and technology, there are more and more methods of eavesdropping in optical fiber communication networks. The technology is more and more sophisticated, and the security of optical fiber communication is greatly threatened. And nowadays there are many eavesdropping techniques that are very subtle and hard to detect. Therefore, the relevant departments and staff should focus on optical fiber communication eavesdropping technology and defense methods to improve the optical fiber communication network eavesdropping.
