Web app attacks are among the most common types of data breaches posing serious threat to a business’ cyber security. These attacks can jeopardize the functioning of your website, inhibit its performance and in most cases, crash the website completely. As most web applications run in the browser, any potential security flaw can permit hackers to exploit the vulnerabilities in the apps and damage the business website.
Common Web App Attacks:
- Cross-Site Scripting (XSS): These attacks use a vulnerable web application to send malicious client side code to be executed by the end user. Once this is done, the hacker can have access to browser’s session tokens, cookies and other sensitive data.
- SQL Injections: This type of attack manipulates the vulnerabilities in the web apps in order to gain access to the databases and other information that they hold. These may include things such as email addresses, names, telephone numbers, postal addresses, bank account information, credit card details etc.
- Directory Traversal: It is a form of HTTP attack in which the cybercriminal installs malicious software on the web server. If the attempt is successful, the hacker can have access to the restricted directories and execute commands that are outside of the server’s root directory.
- Remote Command Execution: This allows the hacker to execute remote and random commands on the host computer through a vulnerable web application. These attacks are largely possible due to insufficient input validation.
Counter Measures Against Web App Attacks
- Set Safe Permissions: Most often, the web apps are attacked due to the preventable vulnerabilities present in them. Make sure you set safe permissions for your files so that they can be written or executed only by the web server.
- Scan For Vulnerabilities: This is extremely important to identify the potential vulnerabilities in your application that may make it open to cyber-attacks.
- Use Application Firewall: Installing and regularly updating firewall can also provide an added layer of defense against web app attacks.
- Restrict Unauthorized Users: Make sure that the write access to your files should be given to a limited number of users. This is applicable both for the server side and web app backend.
