Abstract: In recent years, my country's computer engineering construction has developed rapidly, and the information age has come. Computer network technology has penetrated into various industries, promoted the reform and development of various industries, improved the degree of automation and intelligence of enterprises, and strengthened our country. Overall strength. At this stage, the types and quantities of electronic products in my country have begun to increase, and information categories have shown a diversified development trend. At this point, attention should be paid to the application of computer electronic information engineering technology and security management to carry out more in-depth analysis, to fi nd out the various hidden dangers of current computer electronic information, to explore the characteristics of its information engineering, and to better adopt practical and feasible measures. Technology solves all kinds of security problems, thus guaranteeing computer application security to the greatest extent.
