validation among Users, Stockholders, and delivering important and various services with high availability are part of import dimensions of local search engines. This paper provided a comprehensive research result on Combination of security control tools with main components of local search engines, like crawler, ranker, Indexer and security requirements Consideration in all phases of software development life cycle. We organize the existing research works on securing local search engines based on combination of security standards relevant to software development life cycle of systems with key components of local search engines to help developers, software project managers for implementing security controls and requirements properly.
 

Abstarct- The local search engine systems is one of the indicators of IT industry development in all countries. The safety of these systems arises according to its specific position, with providing users to access to right information in the least possible time. The most effective measures to secure this type of application are assessment and risk management in the early stage of software security. It consists of a set of steps that will help a software team in the applications management during the development process. In order to reduce the risk of this type of systems responce to risk approach is selected. The main objective of this article is assessment and risk management based on information collected from designed questionnaire. As well as to identify important risks, security controls and NIST methodology are used and the results of calculations of the risk level are provided on the basis of known fields.
