Web Application Firewall

Web Application Firewall is essential for protecting websites from cyber attacks.

Web Application Firewall (also known as WAF) can protect websites by filtering and monitoring HTTP traffic between the Internet site and the website.

WAF can protect websites from attacks such as request forgery between CSRF sites, including local files, SQL injection and XSS scripts among others.

The Web Application Firewall only protects against Layer 7 attacks at the application level. A Layer7 attack targets your website directly and can be used to attack it with a lower investment or computing power.

It is important to address critical vulnerabilities in applications that contain 70-80% of them.

To effectively protect against various attack vectors, a company must use a number of specialized tools at each OSI level (network-level Layer 3 filters and application-level Layer 7 filters). use).

Application codes and settings cannot be guaranteed to be perfect. Therefore, it is important to protect data from hackers, spammers, malicious bots, and hackers.

How it works

A Web Application Firewall is a firewall that connects customers to the Internet services they want to use.WAF verifies connections before they are sent to it.

Cross-site scripting is one of the most common attack vectors for applications. It involves injecting malicious code into the browser to steal session cookies and confidential data. It can also modify the content to display false information.

You can configure the web application firewall to enforce a security policy to prevent these types of attacks, block the payload of these attacks, or even prevent them from occurring while they are being hacked. exploit.The

WAF can also protect itself against misconfigured servers. Administrators who fail to follow security best practices and create vulnerabilities by creating insecure settings, such as default passwords and guest accounts, can make it easy for attackers to target. spend more.

These misconfigured systems can be prevented by WAF, which has policies that target multiple login attempts. It forces a CAPTCHA and rejects seemingly insincere protocols/payloads. Safety instructions also apply.
