These activities can be detected and stopped or prevented using special tools. INTRODUCTION The two most common nefarious computer activities are Ping Sweeps and Port Scans. They lead to infringement of systems by intruders which can harm the whole system or network. These probes can be detected and prevented so Its better to be safe than sorry. Port Scans It is one of the most common nefarious computer activities. The intruders hit the target machine and discovers the services being run on it. They plan to attach on any vulnerable service.
