The article presents a signature analysis and its workability to detect security defects in a program code. The authors review typical security defects and techniques for detecting them. They developed a flow chart of the analyzer using signature analysis and data flow analysis for detection of program code defects. The proposed method can be applied in security analysis of web applications.

The problems of a datawarehouse business continuity based on the methods of control and database recovery are discussed. The analysis of a limited stochastic control of databases in comparison with a known deterministic approach is done.
