Application security for APIs, web applications & mobile apps

Application security - protection against the OWASP top 10 security risks

The proportion of data leaks due to a lack of application security rose by 52 % in 2019, and the trend is rising. Web applications and mobile applications are particularly vulnerable to attacks. Added to this are the APIs - the application programming interfaces. DDoS attacks on web applications or APIs can cripple business processes and completely paralyze the company or authority. Modern application security software and tools protect web-based application infrastructures from cyberattacks.

Large organizations actively use more than 100 web applications and mobile apps. However, web-based applications are also becoming more important in small to medium-sized companies. This makes application security programs that protect web-based application structures from cyberattacks all the more important.

Who neglects application security, risks a lot

Cybercriminals use methods to deliberately exploit possible weaknesses in the web application software. Classic IT security systems such as network firewalls or intrusion prevention systems are not able to detect such attacks. Simple network firewalls can only block or allow certain TCP or UDP ports. Application-level attacks using the Hypertext Transfer Protocol (HTTP/HTTPS) are not detected and therefore cannot be proactively blocked. In addition, even next-generation firewalls are not sufficient. They usually do not act as reverse proxies and therefore cannot identify and prevent all attacks that are specifically targeted at applications. They are not able to analyze encrypted data packets and block potential threats. Application security testing identifies security gaps in the web application.

Web Application Firewalls (WAFs) for effective application security

A Web Application Firewall (WAF) for application security protects IT systems in companies and public authorities. It is an important application security tool. The WAF analyzes the data exchange between clients and web servers and checks all incoming requests and responses to and from the web server. If the WAF classifies certain contents as suspicious, access via the WAF is prevented. In particular, a WAF offers protection against attacks that are carried out by so-called injection attacks (SQL-Injections), Cross Site Scripting (XSS), Session Hijacking and other web attacks.

A WAF in combination with a network firewall significantly increases the application security of your company. This means that you are up to date with the latest application security standards when it comes to the requirements of a modern and resilient IT infrastructure. With decades of development and practical experience, the web application firewall effectively protects the corporate network against widespread attacks such as zero-day exploits, SQL injections, cross site scripting or distributed denial of service (DDoS) attacks at the application level. The use of WAF as an application security program worthwhile for large, small and medium-sized companies.

The advantages of our application security tools

  • Optimization of application security in companies and authorities
  • Ensure secure collaboration between employees, partners and customers
  • Protection of enterprise applications from leading providers such as SAP® or Oracle®
  • Reduction of the attack surface and elimination of security holes
  • Respond to cyberattacks and threats before the entire IT is paralyzed

"Web applications, mobile apps and APIs must be specially protected. Traditional network firewalls are not able to stop attacks on web applications and APIs. Firewalls are usually the first line of defense in an organization against cyberattacks from the Internet. Therefore, they should not be missing in application security."
Edouard Viot, Head of Product Management, Application Security

Our recommendations for optimized application security

  • Ask experts to attack your web application, such as through YesWeHack.
  • Make regular updates.
  • Think about backups, even offline.
  • Use a sensible mix of Bot Mitigation, Runtime Application Self-Protection (RASP) and a Web Application Firewall (WAF).
  • Take a look at our webinar here, there you will find further recommendations for more application security.

What is application security?

Application security includes processes, tools and procedures that aim to protect applications from threats throughout their lifecycle. Cybercriminals are increasingly focusing on finding vulnerabilities in enterprise applications. These are then exploited to steal data, intellectual property and sensitive information. It is becoming increasingly important for businesses and government agencies to specifically protect apps such as desktop, web, mobile, and micro-services. Existing security mechanisms such as NextGen Firewalls are not enough.

What is a Web Application?

A web application is an application that resides on the web server and works on the client-server principle. The client - e.g. the PC, laptop or smartphone - executes the corresponding program in the web browser. Web server and client communicate mainly via the http/s protocol. The client requests resources on the web server, such as a web page programmed in HTML. Typical examples of web applications are Facebook, e-mail services such as GMX, Skype for Business, Outlook Web Access, or SAP applications.

What is the OWASP Top 10?

Due to the increased number of attacks on web applications, the international non-profit organization "Open Web Application Project" or OWASP for short is dealing with the top 10 types of attacks on web applications and for some time now also on APIs. Here are the 10 attack types on Web Apps as of 2017:

What is a mobile app?

A mobile app is an application on a mobile device or client such as a smartphone or tablet. The client and web server usually communicate via API interfaces via REST-JSON or SOAP-XML. The mobile app requests data from the remote server or web server and then displays it in the application.

What is an API?

API stands for Application Programming Interface. It is therefore an interface with which it is possible for two applications to communicate with each other. Via APIs, resources and services are made available in the form of interfaces for applications of other parties. APIs pose an increased risk, as more than 80% of web attacks are now API-driven. According to Gartner, API abuse will be the most common attack vector on enterprises by 2022.
