The recent tests on Linux security solutions by AV-Test Lab indicate a worrisome situation

A successful attack normally does not infect the system or the kernel. Rather, it focuses on the applications running on the Linux PC or Web server. They can be more easily hijacked or harnessed as a means to replicate. Major hacker attacks have already been carried out on Web servers via SQL injection or cross-site scripting. But desktop PCs with Linux are also an attractive target. After all, running applications with security gaps are found there as well, e.g. the Firefox browser or tools such as the Adobe Reader.
