If an organization does not adopt a systematic and proactive web security approach and performs vulnerability assessments on certain web applications, the organization cannot defend against the fastest growing attack categories. Web-based attacks can result in lost revenue, theft of personally identifiable financial information, and many government and industry requirements (data security standards for the card industry) that fail to comply with regulatory requirements. Payment (PCI) merchants, HIPAA Healthcare organizations or listed companies of the Sarbanes-Oxley Act. In fact, Gartner Research estimates that 75% of Web security attacks are currently directed at the application layer.

What is a vulnerability assessment for web applications?

Web application vulnerability assessment identifies errors in application logic, configuration, and software coding that can affect availability (for example, insufficient input validation errors can cause an attacker to cause costly faulty applications and systems, or worse, Confidentiality (SQL injection attacks, many other types of attacks that allow hackers to access confidential information) and data integrity (some attacks allow) attackers to modify price information, for example)

Unfortunately, technical errors are not the only problem that needs to be addressed. There is another type of Web security vulnerability that is part of the application’s business logic and the system processes that need to recognize the eye and the human experience. Whether you are an ethical hacker or a cybersecurity consultant, sometimes (especially for newly developed and deployed applications and systems), you need to perform vulnerability assessment in the same way as you. meeting. a pirate

As with technical errors, business logic errors can cause serious problems and flaws in Web security which can be mitigated by getting certified ethical hacker courses. If not allowed, business logic errors can allow buyers to insert multiple coupons into the shopping cart, or website visitors can guess the names of other customers (for example, directly in the shopping cart). Browser address) and they omits the authentication process for accessing other people’s accounts. Due to business logic errors, your business may lose money or customer information may be stolen, and it is difficult to know the reason; you can legally resolve these transactions.

Since business logic errors are not strictly grammar slides, creative thinking is often required to detect them. This is why scanners are not very effective at detecting these problems. Therefore, these issues must be identified by qualified experts who perform vulnerability assessments. This can be an internal cybersecurity expert (a person who is completely unaware of the development process), but an external consultant would be better. You want a professional who has been working for a while. All companies can benefit from third-party audits of their network security. Your internal team may overlook a new look at some of the issues, and because they have helped hundreds of other companies, they will be able to conduct vulnerability assessments and quickly identify issues that need to be addressed.

Perform your vulnerability assessment: the first step

There are several reasons why your business may need to perform a vulnerability assessment. This may be simply an audit of your overall cybersecurity risk posture, through certified ethical hacker courses. However, if your company has several applications and servers, such a serious vulnerability assessment can be very difficult. The first thing to decide is which applications must be evaluated and why. This may be part of your PCI DSS requirements and meets HIPAA requirements. Or a single application that may be network security ready to implement.

Regardless of the scope or purpose of your vulnerability assessment, your architecture should always be considered when creating and applying priorities. For example, all external applications, even those that do not contain sensitive information, should be given high priority. The same applies to external hosting, they are for Internet applications, or they are directly connected to the backend system. All other applications accessed or hosted over the Internet should be a vulnerability assessment. You can’t assume that an application is secure, just because it is hosted by a third party because you can’t assume that there is no risk, just because a web application, a table, or the entire site does not process confidential data. Information In both cases, any Web security vulnerability could directly lead to an attacker’s application and the most important network segment.

Vulnerability assessment

You can now conduct a vulnerability assessment. Believe it or not, most of the work has been done: determine the scope, then categorize and prioritize your application. Now, suppose you have purchased the identified network security scanner who will also perform manual analysis to detect logical errors and you are ready to cope with your application.

Based on the generated report, the application’s security status, you provide a list of high, medium, and low priority vulnerabilities. At this point, you need someone to check the automated results from the vulnerability assessment to detect false positives or fake scanners to find vulnerabilities, but they don’t actually exist. If this sounds overwhelming, don’t worry; we’ll look at how to prioritize and address these Web security vulnerabilities in the next release. At about the same time, your automated vulnerability assessment, manual assessment is in progress. In a manual assessment, the expert will look for an application in a logic error: Is it possible that the user is trading in an unexpected way for the developer? Because of the possibility that someone can change the value of the application from the client to the server to change the price of the item. The manual vulnerability assessment will summarize the cybersecurity list with all detected vulnerabilities and the evaluator should prioritize the risks associated with each issue, depending on mitigating the success of a hacker exploiting the vulnerability and potential risks.

There are now cybersecurity vulnerabilities and security issues which can be handled by getting certified ethical hacker courses, including a list of technologies and logic. If your organization is a favorite, you need to repair it. The challenge now is to prioritize the need to correct so that existing applications can be strengthened and under construction to be corrected and put into production safety.
