Application Security Knowledge


Application security knowledge plays an important role. A growing number of companies and governments are the victims of cybercrime. It can cause economic loss. It also damages the company’s honor. Some companies can not recover from this loss. There are many ways that which is the reason for that.

The easiest way to fight cybercrime is to make sure the code is free of bugs. A malicious hacker may use it. Application security knowledge is the key.

You will find all the information you need in our knowledge base about security bugs and risks. That can affect the security of the program. Finally, developers should write secure code.

Cross-Site Scripting (XSS)

XSS attacks reputable websites if there is any malicious code found. It uses the browser as its breeding ground and transfers malware through browser-side scripts. XSS attacks trick the victim’s browser. It tampers with the browser by sending harmful commands.

Four major forms of XSS are found. They are: Stored Cross-Site Scripting, Reflected Cross-Site Scripting, DOM Based XSS, and Post Method XSS. Application security knowledge plays an important role in fixing it.

SQL Injection (SQLi)

SQL injections in the OWASP Top-10 for several years. it is simply user input bugs that are un-sanitized. SQL statements inject malicious SQL commands to alter, change, or add data. It connects with the DB directly using the user input. SQL injection can lead to fully compromising the app. It can get access to sensitive information in the DB. Application security knowledge is essential for it.

The common ways to fix SQL injection are in the user forms. As an example, a search box in the application or login form.

Privacy Violation

The OWASP Top-10, PCI DSS, HIPPA, MISRA, and others are the policy and privacy compliance standards. The normal focus of the attacks is credentials. Credit card info is another attack option. However, addresses, mobile numbers, and e-mails are also the normal targets for attacks.

There are some primary violations behind these abuses. As an example, not secure user data. In addition, showing sensitive information is also a primary violation.

Cross-site Request Forgery (CSRF)

CSRF attacks manipulate web app to authenticate an entry by the user. It can threaten the entire app’s sensitive areas. Such as, changing the user’s password. This is “session-riding,” which enables the hacker without prior notice or permission to use active sessions on behalf of the victim. They are masking it as a regular user request. That’s why its hard to find the issues.

OS Command Injection

OS Command Injection attacks in the web app The hacker tries to run instructions at the system’s level. Moreover, these injections allow the hacker to override user rights and run malicious OS commands. In addition, OS command injections can also be blind or error-based, as with SQL injections.

LDAP Injection

LDAP stands for Lightweight Directory Access Protocol. It works over the TCP/IP stack. It offers the correct method to view and change data directories. It is widely used in the development of intranets. It will hamper the system.

Path Traversal

Not properly managed access to the web app content is the main reason for Path Traversal attacks. It provides hackers with unwanted access. Finally, it attacks the web server.

The injection flaws perform these attacks. It is usually conducted with the assistance of crawlers. It is the most common reason for resource injections.

Session Fixation

The session fixation attack is a class of session hijack. It steals the established session between the client and the web server after the user logs in. Instead, the Session Fixation attack fixes an established session in the victim’s browser, so the attack starts before the user logs in.

Session Hijacking

HTTP communication uses many different TCP connections. The webserver needs to recognize every user’s connections. The most useful method depends on a token that the Web Server sends to the client browser after successful client authentication. A session token is normally composed of a string of variable width. It uses in various ways like in the URL, in the header of the HTTP request as a cookie, in other parts of the header of the HTTP request, or in the body of the HTTP request.
