Introduction

Botnet can be defined as robot and network. It is the combination of two different technologies to provide more advancement in the technology. A botnet is also known as connection of many computers together to perform multiple functions.  Botnet is a way to exploit the device and applicant it code which leads to change it as a bot/ robot. Some famous botnet is Zeus, Waledac and Kelihos. In today’s era everything is connected to IoT (Internet of Things) from toaster to doors, from web cams to Air Conditioners.

Botnet is a used for distribution denial of services attacks and allow to control the devices and its connection. It can affect the society in direct or indirect way. As the houses offices and even vehicles are connected by internet, it can carry many harmful actions. It can attack websites and mail, and which the application of DDos it can generate spam mails and many viruses.

 

Three variants of Botnet

1. Star Wars’ Twitter Botnet: This variant of Botnet was found in 2017. In such botnet around 35,000 twitter bots were generated and refer as Star War Botnet. Many followers were increase and decrease in various accounts. Some sent spam and fake accounts are generating automatically. They can even control the public vies and opinions and also affect many researches works. The main issue arrive is about the selection of authenticate account on twitter. It was a huge failure of cyber security and created a awareness for other social sites for such malwares.
2. WireX Android Botnet: This attract of botnet was seen initially on 2^nd August 2017. This enables Content Delivery network and all the important content is passed to the attackers. This botnet is primary attack on android devices. Gradually Google play store app came in contact with this malware. More than 100 countries came together for tracing the nodes and to develop the solution.
3. The Reaper IoT Botnet: The Reaper IoT Botnet infected millions of networks. As the IoT became the most emerging technology used in business. Its malware occurs on 20 October 2017 and spotted by Qihoo 600 Netlab. It is a part of Mirai Botnet. It effects routers, camera, Storage box Wi-Fi points and other digital records. It is the biggest threat on the IoT. The most effect protection against such kind of malware is to update the software with more security.

Botnet architecture, operation and communication

There are 5 key architecture:

1. Multi-Server C&C Topology

2. Star or Centralized C&C Topology                  
3. Peer-to-Peer Topology
4. Hierarchical C&C Topology
5. Random or Unstructured C&C Topology

Process of Botnet: As its appellation specifies, several number of robots are associated in a system for mismanagement. This is done to increases the system of cybercrime. To the criminal who performs these types of activities are provided with a name called Botmasters. To pass on a disease such as virus to supreme amount, botnet outbreaks at concentrated connected devices. Reasonably than confronting approximately specific industry, company and people, this malware looks for those systems over internet that are defenceless. Moreover, it practices meting out control and properties of some devices that it was attacked.

Potential threats posed by a Botnet:

The threat depends upon the performance of the Botnet. The risk is more as much of the elements affects the Botnet.  The factors such as capacity of attack. Destruction, concealment, transparency, resistance and many more. If the performance of the botnet is not good, the risk will be more of attacking. If the performance is good, it will provide desired results. As soon as a botnet becomes achieved or grows an instruction to attack by an attacker demonstration the clearness of botnet. By the means of regulator arrangement, this transparency is principally unspoken. To control the botnet as a complete the attacker inserts the control information and guidelines into the assembly. This arrangement communicates the gratified in dissimilar knobs.

Recommendations

I'll recommend the client to proceed with the network security feature as network health, irrespective of the type or complexity of a company, is one of the most critical things to remember while operating on the Internet, LAN or any process. Although no network is resistant to threats, the safety of consumer data requires a secure and effective network security framework. A strong safety network allows company to reduce the danger that data loss and vandalism may fall prey to. Security in your network helps secure your workstations from spyware. This therefore guarantees the safekeeping of confidential knowledge. The network security architecture offers various layers of defense to deter attacks by splitting data into many modules, encrypting such modules, as well as transferring it through separate routes, avoiding instances such as eavesdropping.

While in most of the popular technology periodicals, the Network has rendered the network protection framework a focus, the value of the network security system remains unknown in other areas of the world. The protection network program is an essential part of the design and maintenance of the network. The successful management of the network guarantees the integrity of all routes, connections as well as databases. Network security is, momentarily, an excellent network capability that guarantees transparency, confidentiality, honesty including, above all, defense from several internally and externally risks, including email-based security problems for the network, denial of access attacks, worms as well as trojans for the communication networks, or even wireless security attacks.

Discussion

As per the author, Botnet are alone of the highest risked attack s that can harm the complete network of the organisation. Over the recent research it is found that botnet attack can restrict the working of various devices connected to the network such as mobile devices, laptops, server, and more and also effect the performance of the network. Botnet attack can block all the transmission within a network as the bots used in these evacuate all the memory and process from the devices connected to the network.

 

Conclusion

The report above provides a description about the Botnet technology. The helps in evaluating various threats so that the plans can be mitigated and desired results can be obtained. The report talks about the introduction of botnet and its impact played over the society. With the help of various diagrams, more details description was also provided. It describes about the communication, its architecture and botnet operations. The report discusses the botnet potential threats along with providing recommendations to improve upon the performance. Some of the techniques are used with respect to mitigate the attacks of botnet.
