Abstract:work security problem, directly relates to domain the and so on a national politics, military, economy security and the stability. At present the hacker is rampant, in the average every 18seconds worlds has a time of hacker attack to occur. Therefore, enhances to work security important understanding, enhancement guard consciousness, the strengthened guard measure, is guaranteed the information industries continues the important guarantee and the prerequisite which stably develops.
In the article first elaborated the radical change which the work security connotation occurs, elaborated our country develops the nationality information security system importance and the establishment has the Chinese characteristic work security system necessity, as well work safety control. Further elaborated work topology safe design, including work topology analysis and work security brief analysis. Then specifically narrated work firewall security technology classification and it’s the main technical characteristic, the firewall deployment principle, and the position which deployed from the firewall in detail elaborated the firewall choice standard. Meanwhile has made the brief analysis on the exchange of information encryption technology classification and the RSA algorithm, elaborated its security system constitution. Finally analyzes work security technology the research present
