Compromised computers or BOTNETs are unarguably the most severe threat to the security of internet community. Organizations are doing their best to curb BOTNETs in every possible way, spending huge amount of their budget every year for available hardware and software solutions. This paper presents a survey on the security issues raised by the BOTNETs, their future; how they are evolving and how they could be circumvent to secure the most valuable resource of the organizations which is data. The compromised systems may be treated like viruses in the network which are capable of performing substantial loss to the organization including theft of confidential information. This paper highlights the parameters that should be considered by the organizations or Network administrators to find out the anomalies that may point to the presence of BOTNET in the network.
