Webanwendungen - Die Schwachstelle der Sicherheit

Druckfreundlich, PDF & E-Mail

Today’s hackers are becoming increasingly sophisticated in planning and executing well designed multi-vector attacks. It used to be that attackers only employed a singular strategy to attack end users or computer systems. For example, virus attacks used to be spread by an email attachment. However with the mass adoption of email security products such as the Barracuda Spam & Virus Firewall and increased public awareness, these attacks are no longer effective since most attacks are quickly contained or blocked once detected.

A hacker is at once a rogue computer expert and a social psychologist who understands how people react. In order to have any efficacy, today’s hacker must now use a number of mechanisms in tandem in order to trick users into sending personal data or downloading malicious software. A well disguised spam email that takes a user to a legitimate Web site that has been compromised in advance with a Cross-Site Scripting (XSS) attack to use social engineering techniques to steal personal or financial information is a typical example of the elaborate web a hacker weaves.

Web Applications – The Weak Link

An old adage states that “you are only as strong as your weakest link.” Organizations have made investments in network firewalls and IDS/IPS systems to protect their networks. They have invested in security products to protect their email.  However, many organizations leave Web applications unprotected.  Considering that 75-90 percent of all attacks today are against Web applications, there is shockingly little security awareness and protection deployed to protect Web applications.

Because of all the dynamic feature functionality expected by users, Web applications use numerous programming languages & protocols to build efficient, multi-tier applications. A small application can easily have hundreds of thousands of lines of code, use more than 4 programming languages and be written by teams of engineers who might not have met in person before or may not work for the organization anymore. Given all the moving parts that are required to build an application, it is nearly impossible to build a perfectly secure application. A US Department of Defense study indicated that there are nearly 15 critical security defects in every thousand lines of code.  According to Forrester Research, even if a security defect is found, it still takes on average 30-90 days before it is fixed, tested, and applied to the application.  Hackers know about the difficulty of writing secure Web applications and they readily exploit vulnerabilities for large financial gains.

Your corporate Web sites, eCommerce portals, and other Web properties need protection. If you can access an application from a browser, then it is a Web application. Internal applications accessed by your employees such as Outlook Web Access, Oracle Financials, Microsoft SharePoint, SAP, Peoplesoft, or Issue Tracking Systems are all Web applications that need protection from attacks. What are you doing to protect them and how can you manage the security on the numerous applications required to keep your business running?
