OWASP Top 10 is an online document on OWASP’s website that provides ranking of and remediation guidance for the top 10 most critical web application security risks. The report is based on a consensus among security experts from around the world. It represents a broad consensus about the most critical security risks to web applications. Globally recognized by developers as the first step towards more secure coding. The OWASP Top 10 is important because it gives organizations a priority over which risks to focus on and helps them understand, identify, mitigate, and fix vulnerabilities in their technology. Each identified risk is prioritized according to prevalence, detectability, impact and availability
OWASP (Open WebApplication Security Project) is an open community, non-profit organization with a strong authority to help governments or enterprises understand and improve the security of web applications and web services. It will provide some security tools also have the main security threats of the day to organize the release, is a security tool applied to web scanning and attack, but also open source, in the interception of proxy and scanning attacks is more powerful. For OWASP Top 10 content there is still a lot to learn and practice testing penetration, and this is a security workers need, of course, in an era of Internet, security sometimes in places they can not see, so never think you do something must be safe and hidden, but also do not have the idea of attacking the behavior of others, a good era of Internet is built by every A good Internet era is built by every Internet user.

Each year, OWASP lists a number of software at risk of vulnerability for ranking, testing each one for vulnerability. in 2017, they selected categories based on incidence to determine likelihood. By 2021, they use the data to give rankings for exploitability. Not only do they use only the data, but they also talk to a number of experienced professionals and ask them about what they have found and the trends included in the data.
The article publishes the latest installment of the OWASP Top 10 in 2021. There are three new categories, four categories with naming and scoping changes, and some consolidation in the Top 10 for 2021. The process of data collection and data analysis is also introduced.
Many Application Security (AppSec) programs try to run before they can crawl or walk. These efforts are doomed to failure. We strongly encourage CISOs and AppSec leadership to use OWASP Software Assurance Maturity Model (SAMM) to identify weaknesses and areas for improvement over a 1-3 year period. The first step is to evaluate where you are now, identify the gaps in governance, design, implementation, verification, and operations you need to resolve immediately versus those that can wait, and prioritize implementing or improving the fifteen OWASP SAMM security practices. OWASP SAMM can help you build and measure improvements in your software assurance efforts.
The Open Web Application Security Project (OWASP) is an open community dedicated to enabling organizations to develop, purchase, and maintain applications and APIs that can be trusted. By design, the OWASP Top 10 is innately limited to the ten most significant risks. Every OWASP Top 10 has “on the cusp” risks considered at length for inclusion, but in the end, they didn’t make it. No matter how we tried to interpret or twist the data, the other risks were more prevalent and impactful.
There are data factors that are listed for each of the Top 10 Categories, here is what they mean:
1.CWEs Mapped: The number of CWEs mapped to a category by the Top 10 team.
2.Incidence Rate: Incidence rate is the percentage of applications vulnerable to that CWE from the population tested by that org for that year.
3.Weighted Exploit: The Exploit sub-score from CVSSv2 and CVSSv3 scores assigned to CVEs mapped to CWEs, normalized, and placed on a 10pt scale.
4.Weighted Impact: The Impact sub-score from CVSSv2 and CVSSv3 scores assigned to CVEs mapped to CWEs, normalized, and placed on a 10pt scale.
5.(Testing) Coverage: The percentage of applications tested by all organizations for a given CWE.
6.Total Occurrences: Total number of applications found to have the CWEs mapped to a category.
7.Total CVEs: Total number of CVEs in the NVD DB that were mapped to the CWEs mapped to a category.
This installment of the Top 10 is more data-driven than ever but not blindly data-driven. Looking at the contributed data is looking into the past. AppSec researchers take time to find new vulnerabilities and new ways to test for them. It takes time to integrate these tests into tools and processes. By the time we can reliably test a weakness at scale, years have likely passed.To balance that view, we use a community survey to ask application security and development experts on the front lines what they see as essential weaknesses that the data may not show yet.

Top Ten, first published in 2003, is regularly updated. [6] It aims to increase awareness of application security by identifying some of the most important risks facing organizations. [7][8][9] Many standards, books, tools, and organizations refer to the Top 10 program, including MITRE, PCI DSS, [10] DisA-STIG, and FTC.
The OWAPS Top 10 focuses on the 10 most critical risks and is regularly updated. It is recommended that this document be used as an “awareness document” for organizations to reduce security risks. This document includes attack scenarios and prevention methods related to the following 10 risks: Injection, Broken Authentication, Sensitive Data Exposure, XML External Entity (XXE), Broken Access Control, Security Misconfiguration, Cross-Site Scripting (XSS), Insecure deserialization, use of components with known vulnerabilities, insufficient logging and monitoring.
There are three new categories, four categories with naming and scoping changes, and some consolidation in the Top 10 for 2021.This installment of the Top 10 is more data-driven than ever but not blindly data-driven. We selected eight of the ten categories from contributed data and two categories from the Top 10 community survey at a high level. We do this for a fundamental reason, looking at the contributed data is looking into the past.
The Open Web Application Security Project (OWASP) is an open community dedicated to enabling organizations to develop, purchase, and maintain applications and APIs that can be trusted. There are three new categories, four categories with naming and scoping changes, and some consolidation in the Top 10 for 2021. We’ve changed names when necessary to focus on the root cause over the symptom. The OWASP Top10 2021 are as follows:
A01:2021-Broken Access Control
A02:2021-Cryptographic Failures
A03:2021-Injection
A04:2021-Insecure Design (new)
A05:2021-Security Misconfiguration
A06:2021-Vulnerable and Outdated Components
A07:2021-Identification and Authentication Failures
A08:2021-Software and Data Integrity Failures (new)
A09:2021-Security Logging and Monitoring Failures
A10:2021-Server-Side Request Forgery (new)
OWASP top 10 provides a detailed explanation of each risk problem, including how the problem occurs, whether the application is vulnerable, how to prevent, and some case scenarios. An application security program plays an integral part in keeping an organization’s assets secure. The program should effectively track all the information assets and manage the security of the systems from breaches in confidentiality, integrity, and availability.
A01:2021-Broken Access Control moves up from the fifth position to the category with the most serious web application security risk;
A02:2021-Cryptographic Failures shifts up one position to #2;
A03:2021-Injection slides down to the third position.
Important takeaways that I learned from the OWASP Top 10 are OWASP core principles of being free and easily accessible to any users. The Open Web Application Security Project or OWASP is an international non-profit organization dedicated to web application security. OWASP is periodically updated to report concerns for web application security, focusing on the 10 most essential cyber risks. According to the report, the most common types of application security risk are Injection, Broken Authentication, sensitive data Exposure, XML External Entities, and Broken Access Control.
The Open Web Application Security Project (OWASP) is a foundation that tries to improve web application security. This group lists the top 10 most common vulnerabilities that are impacting applications and provides information on each vulnerability such as the risk, how to mitigate the vulnerability, attack scenarios, and references.
Between increasing attacks and regulatory pressures, organizations must establish effective processes and capabilities for securing their applications and API. Achieving application security requires many different parts of an organization to work together efficiently, including software development, security audit, and executive management. Organizations should adopt this document and start the process of ensuring that their web applications minimize the risks.

This article introduces the latest issue of the OWASP Top 10 and their changes.
One of the difficulties of using the OWASP Top 10 as a standard is that we document appsec risks, and not necessarily easily testable issues. For example, A04:2021-Insecure Design is beyond the scope of most forms of testing. Another example is testing in place, in use, and effective logging and monitoring can only be done with interviews and requesting a sampling of effective incident responses. A static code analysis tool can look for the absence of logging, but it might be impossible to determine if business logic or access control is logging critical security breaches. Penetration testers may only be able to determine that they have invoked incident response in a test environment, which are rarely monitored in the same way as production.
The OWASP Top 10 – 2017 is based primarily on 40+ data submissions from firms that specialize in application security and an industry survey that was completed by over 500 individuals. This data spans vulnerabilities gathered from hundreds of organizations and over 100,000 real-world applications and APIs. The Top 10 items are selected and prioritized according to this prevalence data, in combination with consensus estimates of exploitability, detectability, and impact.
One point i learned from OWASP Top 10 is cryptographic failures, sensitive data such as passwords, credit card numbers, health records, personal information, and business secrets need to be properly protected because if negative things such as exposure of sensitive data happen, firms will loss a lot, money, customes and a lot. Helpful, it listed several methods to prevent the failure. It can help us a lot.
We can learn that the OWASP Top 10 is important because it lets organizations prioritize which risks to focus on and helps them understand, identify, mitigate, and fix vulnerabilities in their technologies. Prioritizing each identified risk based on prevalence, detectability, impact, and availability represents a broad consensus on the most critical security risks for web applications.

Every year, OWASP lists some software with vulnerability risks and conducts vulnerability testing for each software. Helps governments or businesses understand and improve the security of web applications and web services.

I acquired a lot of information which associate with OWASP, to begin with, I understood the concept and function of OWASP, OWASP is an open community that wants to help some organizations to avoid and address the problem in their information system, and let them know how to protect their important information or data cannot be stole by attackers.
An open web service is a powerful open web application that can help an enterprise, a non-profit organization, or a wasp. OWASP top 10 explains each risk problem in detail, including how the problem occurs, whether the application is vulnerable, how to prevent it, etc.
We strongly encourage CISOs and AppSec leadership to use OWASP Software Assurance Maturity Model (SAMM) to identify weaknesses and areas for improvement over a 1-3 year period. The first step is to evaluate where you are now, identify the gaps in governance, design, implementation, verification, and operations you need to resolve immediately versus those that can wait, and prioritize implementing or improving the fifteen OWASP SAMM security practices.
From OWASP,I learn that there may be authentication weaknesses if the application:
1.Permits automated attacks such as credential stuffing, where the attacker has a list of valid usernames and passwords.
2.Permits brute force or other automated attacks.
3.Permits default, weak, or well-known passwords, such as “Password1” or “admin/admin”.
4.Uses weak or ineffective credential recovery and forgot-password processes, such as “knowledge-based answers,” which cannot be made safe.
5.Uses plain text, encrypted, or weakly hashed passwords data stores (see A02:2021-Cryptographic Failures).
6.Has missing or ineffective multi-factor authentication.
7.Exposes session identifier in the URL.
8.Reuse session identifier after successful login.
9.Does not correctly invalidate Session IDs. User sessions or authentication tokens (mainly single sign-on (SSO) tokens) aren’t properly invalidated during logout or a period of inactivity.
