Critique Report on Demand-Driven Software Vulnerability Detection for C Program Software Vulnerability is an unintended flaw in software code or system that leaves it open to the potential for exploitation in the form of unauthorized access or malicious behavior such as viruses, worm and other forms of malware [12]. In order to avoid vulnerabilities in a software, security testing has been implemented, which helps in detecting software vulnerabilities effectively. Some of the methods which help in security testing are black box testing and white box testing [12]. Black box testing involves in generation of the test case using strategies like mutation, without considering source code structure. Which are fed to the system later [12]. The …show more content…
It has a problem with path explosion and often fails in a large system. The basic idea behind demand driven vulnerability testing is that to have a client site module which will trigger the vulnerability that has been detected by the system for the given path that it takes. If it discovers that the taken path has the vulnerability then it terminates the execution. If the program ends up finding a new path that was not taken previously then it passes the path information to the testing site module to find vulnerabilities in it [12]. At the testing site module it first recovers the execution path which will be the sequence of steps performed by the client then symbolic execution is employed on the path to find if there are any vulnerability is detected. If there is vulnerability is detected the testing site creates the signature and passes it to the client site. Thus in this approach it uses both the advantages and also the disadvantages of the above described systems [12]. The challenges that are faced by the above system are that the time and space constraint which involved in storing the bit pattern for each flow path in the client side for larger systems and also the security issue which helps the attacker to find the path and privacy of the client [12].

Discuss approaches to a penetration test and vulnerability scan in terms of black box, white box and gray box tests.
9. NIST 800-42 encompasses security testing and penetration testing. It includes how network security testing fits into the system development life cycle and the organizational roles and responsibilities related to security testing. It also introduces the aspect of available testing techniques, their strengths and weaknesses, and the recommended frequencies for testing. Finally, it gives strategies for deploying network security testing, including how to prioritize testing activates.
Penetration testing is the attempt to identify security weaknesses within the IT infrastructure of an
Using other automatic vulnerability assessment tools, it can validate reports and prove the vulnerabilities are not a false positive and can be exploited. Which in turn can be utilized to test for new exploits that surface almost consistently on the company’s privately facilitated test servers to comprehend the adequacy of the exploit. Metasploit is likewise an excellent testing instrument for the company’s interruption recognition frameworks to test whether the IDS is effective in preventing the assaults that the corporation uses to sidestep it. The framework is one of the preferential tools in the security research communal, independently responsible for creating a portion of the most refined assaults against programming and frameworks. In the right hands, this tool can offer a very powerful means of uncovering security vulnerabilities in software and assisting in their repair (Shetty,
Failures caused by attacks exploiting these vulnerabilities are very costly. According to a NIST report [3], the U.S. economy spends $59.5 billion in breakdowns and repairs cost caused by software errors. Software security, which is software such that it can continuously under malicious much attention recently due the idea of engineering function correctly and attacks [4], has attracted to the fact that reactive
Based on the fundamental principle that prevention is better than cure, penetration testing (pen-testing) is essentially an information assurance activity to determine if information is appropriately secured. Conducted by penetration testers, sometimes referred to as ‘white hats’ or ethical hackers, these tests use the same tools and techniques as the bad guys (‘black hat hackers’), but do so in a controlled manner with the express permission of the target organization.
Different types of content and some when the sensitivity of them is included in web-based applications, e.g., textual, graphical data, audio and video to the end users by using hypermedia. Sometimes sensitive process like tax calculation, completing and executing financial transactions and tracking of customer profiles are performed in a web-based application. Also, the user of a web-based application can be of any nationality. Efficient test data is needed to verify and validate the important aspect of the success of software. Furthermore, context-driven testing methodologies would be provided in unstable environments where conditions changes.
Hence, we use Metasploitable, a linux based VM with potential vulnerabilities, to conduct the tests.
Fabricated test data is prepared and integrated into the program, it is run through the application and the results are compared to the results that are expected to be obtained. The test deck method depends a lot on the abilities of the auditor to anticipate and capture all deviations and exceptions. The auditor must be able to find and use different scenarios that may arise in order to detect errors. An auditor must be able to analyze the data appropriately and carefully so that any errors are not overlooked. Auditors can use another technique similar to the test deck method. The test deck method is used by not incorporating it with live data. However, integrated test facility method is used the same way except that it is incorporated with live data and is run through the client’s system along with normal transaction processing. The last technique used is called parallel simulation. With this technique the auditor uses audit software to reproduce a part of an application or the entire application to test data on. The data that is run on the client’s original application is used again and run on the reproduced program and the results are compared and any errors analyzed.
Fault tolerance was proposed as a technique to allow software to cope with its own faults in a manner reminiscent of the techniques employed in hardware fault tolerance [4]. It is the essential element that is needed for the creation of the next generation of reliable computer systems. Unreliable software is a very important factor that can have a terrible effect on the software’s quality and the software’s cost. It also changes the time of software delivery. When the test results of the systems differ the software ends up having a defect. A defect is any significant, unplanned event that occurs during a software test.
Since reliability issues have become one of the most concern issues in software development. However by conducting software testing, it does not ensure free defect failure software but it can increase the reliability of a software product. Although it is necessary to test the software thoroughly, it is impossible to have exhaustive testing. This is the reason interaction testing have been the most used testing. Especially pairwise testing which use two way interactions to find software defect. This had become the driven force for this research.
In software testing, software developers use network virtualization to test software under development in a simulation of the network environments in which the software
%Given these results, they proposed combining static analysis tools with dynamic testing to find security holes. Their idea is to first test the program using static analysis tools and later using a dynamic detection to confirm the existence of the weaknesses detected found in the static analysis.
This kind of attack can bring about major harm in light of the fact that a few services charge the userbased on the traffic. We have made a proof-of-idea attack to demonstrate the feasibility of such assaults. To address these security issues, we have composed and implemented an answer in resource labeling. Marks are utilized to track network service usage, and are exchanged between resources and processesas a result of either execution or access. Exploratory assessment of our system demonstrates that it sufficiently anticipates such attacks.
