This paper provides a taxonomy for computer program security flaws together with an appendix that carefully documents 50 actual security flaws. These flaws have all been described previously in the open literature, but in widely separated places. For those new to the field of computer security

University Nijmegen have discovered a serious security flaw in a widely used type of contactless smartcard [9], also called RFID tag. It concerns the ”Mifare Classic ” RFID card produced by NXP (formerly Philips Semiconductors). Earlier, German researchers Karsten Nohl en Henryk Pltz pointed out

security, models, flaws, branching process, analytic A simple model of the dynamics of flaws within a software security system is presented. We demonstrate how this model can be fully captured by a Galton-Watson branching process and thus can be effectively calculated upon. Using the limit

Web security is an important area of research. This work has focused on web securing schemes. The primary concentration is to interpret the way to handle the SQL Injections. It is one of the many web attack methods used by hackers to steal data from industries. It is one of the most usual technique

, the users can invoke them only through the granted functions. This achieves access control in abstract operation level. Access control utilizing encapsulated functions, however, easily causes many “security flaws ” through which malicious users can bypass the encapsulation and can abuse the primitive

In resent years, Popescu proposed several group signature schemes based on the Okamoto-Shiraishi assumption in [8--11], and claimed his schemes are secure. However, this paper demonstrates that these schemes are all insecure by identifying some security flaws. Exploiting these flaws

of application requirements and security needs and suggest how they can both be accommodated. 1 Introduction This paper describes several security flaws we found in Sun's HotJava Web browser and attacks that exploit those flaws. We have implemented denial of service and man-in-the-middle attacks. We have

this article. Problems With WEP WEP has several serious inherent problems. It does not meet its fundamental goals of wired-equivalent confidentiality. It also fails to meet the expected goals for integrity and authentication

this paper is to show an efficient decision algorithm for detecting a security flaw under a given authorization. This problem is solvable in polynomial time in practical cases by reducing it to the congruence closure problem. This paper also mentions the problem of finding a maximal subset of a
