Resumen
The article focuses on several measures that can be taken to narrow down malicious attacks on Web servers by intruders and hackers which are prime concerns of organizations as well as users who access them. The article suggests a server-based Web agent to verify the integrity of Web pages from malicious attack and described its implemented results. It is also found that a Web server's central processing unit overhead due to application of hash algorithm is negligible compared to transmission delays. The experimental findings on time metrics can be used as a guide for adopting this technique to Web sites with different configurations. The proposed server-side integrity check protects the interest of Web server providers and clients. This together with integrity verifications on the client's site provide confidence to users where security sensitive online transactions are concerned. A further attempt is made to expand this solution to include verification of dynamic contents in the absence of a secure communication line between the Web server and clients.
