Application security challenges vary, from large-scale network disruption to targeted database manipulation. Some examples of application security risks include:

• Cross site scripting (XSS) is a type of vulnerability that allows an attacker to inject client-side scripts into webpages. For example, an attacker may exploit XSS on an e-commerce website and embed HTML tags in comments. Comments can then link to files that steal visitor session cookies on another site—allowing them access to anything from credit card numbers on down.
• Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks enable remote attackers to overwhelm a targeted server or the infrastructure that supports it with an excessive amount of legitimate traffic. This illegitimate traffic eventually denies service to real users, shutting down the server.
• A SQL injection attack is a technique that attackers use to exploit vulnerabilities in databases. Such an attack can reveal things like usernames and passwords, or allow attackers to manipulate or destroy data, or modify or create user permissions.
• Cross-site request forgery (CSRF) is a technique hackers use to impersonate authorized users after tricking them into making an authorization request. High-level users are frequent targets for CSRF attacks because once the account is compromised, the attacker can remove, modify, or destroy data.

Companies must address application security risks that could compromise sensitive data because the damage from breaches is extreme and sometimes permanent. As more companies move their apps and sites online, information security generally will become even more complex, and critical. This means application security technologies will grow ever more crucial to the security of business, the apps that run companies, and their data security.

Web application security is a priority for many organisations. Hackers look for vulnerabilities in web applications, which can put your organisation at risk. Securing web applications requires a range of actions that, when coordinated and consistent in their approach, can defend them from many forms of attack. Technologies including Web Application Firewalls (WAFs) help by monitoring traffic between the web application and the user, to block anything that is potentially malicious. Vulnerability scanning solutions can also help by identifying and addressing any issues in the application.
