Measuring Security IT Success - In a time where budgets are constrained and Internet threats are on the rise, it is important for organizations to invest in network security applications that will not only provide them with powerful functionality but also a rapid return on investment.

In most organizations IT success is generally calculated through effectiveness, resource usage and, most importantly, how quickly the investment can be returned. To correctly quantify the ROI of information technology, organizations usually measure cost savings and increased profits since the initial implementation. Additionally, ROI can also be affected based on the overall impact the investment has on employee productivity and overall work environment of the company.

- A buffer overflow occurs when a program or process tries to store more data in a temporary data storage area than it was intended to hold. Since buffers are created to contain a finite amount of data, the extra information can overflow into adjacent buffers, corrupting or overwriting the valid data held in them.

Thank you for reading the LinuxSecurity.com weekly security newsletter. The purpose of this document is to provide our readers with a quick summary of each week's most relevant Linux security headline.
