Abstract

We propose SigFree, a realtime, signature-free, out-ofthe- box, application layer blocker for preventing buffer overflow attacks, one of the most serious cyber security threats. SigFree can filter out code-injection buffer overflow attack ....etc

ABSTRACT

RFB (Remote Frame Buffer) protocol enables remote users to share the desktop of the server either exclusively or on a sharing basis.

RFB (remote frame buffer) is a simple protocol for remote access to graphical user
interfaces. Because it works at the frame buffer level it is applicable to all windowing
systems and applications, including X11, Windows 3.1/95/NT and Macintosh.
The remote endpoint where the user sits (i.e. the display plus keyboard and/or pointer) is
called the VNC client. The endpoint where changes to the fram ....etc

Chapter 1. Introduction
By combining the C programming languageâ„¢s liberal approach to memory
handling with specific Linux filesystem permissions, this operating system
can be manipulated to grant unrestricted privilege to unprivileged accounts
or users. A variety of exploit that relies upon these two factors is commonly
known as a buffer overflow, or stack smashing vulnerability. Stack smashing
plays an important role in high profile computer security incidents. In order
to secure modern Linux systems, it is nec ....etc

Buffer Overflow , Virus & Worms and The “stacheldraht”  service attack tool

abstract
over flow
A process in memory:
- text (Program code; marked
read-only, so any attempts to
write to it will result in
segmentation fault)
- data segment (Global and
static variables)
- stack (Dynamic variables)

The process is blocked and is rescheduled to run again with a larger memory space if the user attack exhausts available memory.
