EC-Council Web Application Hacking Security Certification (WAHS)

Yes, a web application can be hacked.  Hackers typically use malicious code, such as viruses, worms, and Trojan horses, to gain access to a web application.  Additionally, hackers may exploit vulnerabilities in the application itself, such as weak passwords, insecure coding practices, and unpatched software.

Web application security is a branch of cyber security that focuses on protecting websites, web applications, and web services from malicious attacks.  It is an important part of an organization’s overall security program and involves a comprehensive set of security measures designed to protect websites, web applications, web services, and their associated data from unauthorized access, misuse, and modification.  These measures include input validation, output encoding, authentication, and authorization.  Web application security also involves monitoring and testing to ensure that security measures are effective and up to date.

By using the following protocols, anyone can save web applications from being compromised:

• Secure authentication
• Input validation
• Encrypt sensitive data
• Implement access control
• Use a web application firewall
• Monitor and log activity
• Perform regular security scans

Web application vulnerabilities are security weaknesses commonly found in web applications, such as web browsers, web servers, and web services.  These vulnerabilities can be exploited to gain unauthorized access to sensitive data, cause a denial of service, or perform malicious code injection.  Common web application vulnerabilities include cross-site scripting (XSS), SQL injection, broken authentication, and insecure direct object references.

Some basic web application attacks are as follows:

• SQL Injection
• Cross-Site Scripting (XSS)
• Cross-Site Request Forgery (CSRF)
• Buffer Overflows
• Malicious File Execution
• Password Attacks
• Privilege Escalation

The most common way web applications are hacked through injection attacks, such as SQL injection.  Injection attacks are used to gain access to a website’s database and potentially sensitive information.  Other common web application hacking techniques include cross-site scripting (XSS), remote file inclusion (RFI), and cross-site request forgery (CSRF).

Web application security is important because it helps protect websites and the sensitive data stored on them from malicious attacks.  These attacks can be devastating, causing financial losses, loss of customer trust, and reputational damage.  Web application security can help to protect against malicious attacks, such as SQL injection, cross-site scripting, and session hijacking, as well as other types of threats.  It is also important to ensure that websites are regularly updated to patch any security vulnerabilities.
