    Network is a gathering of hubs that interrelate with each other for switch over the data. This data is vital for that hub is saved secretly. Attacker in the framework may catch this private data and twisted. So security is the real issue. There are a few security Attacks in network. One of the real scares to web analyze is DDoS Attack. It is a vindictive push to suspending or suspends administrations to destination hub. – Denial of administrations (DOS) and Distributed Denial of administrations (DDoS) are the significant issue against network security and digital security that permit a customer to perform exceptionally costly and key operations, before the network administrations are given to the regarded customer. However An Attacker might have the capacity to control the DOS and DDOS or implicit illustrations preparing Unit (GPU) and have the capacity to crush customer perplexes. In this paper we concentrate how to safeguard DOS and DDOS Attacker for being controlling the puzzlesolving strategies. So now we present another customer riddle alluded to as Software Puzzle. It is not at all like past riddle, which produce their riddle calculations ahead of time, a riddle calculation in the present programming riddle plans is haphazardly created simply after a customer solicitation is gotten from the server side. t the Denial-of-administration and disseminated DoS Attack a customer riddle strategy is actualized. Keeping in mind the end goal to avert further Attack in network and to improve the security the solicitation that is given by the customer and the document sent by the server to customer is in scrambled structure. One downside of existing framework is if the assailant distinguishes the port, he can barge in or meddle in the correspondence and surge DOS Attack and can hack conveying information. The strategy utilized is clarified as takes after. To start with the customer needs to explain a riddle produced by the server. At that point the customer checks the inactivity of the document that must be gotten to from server database. The customer can test the inactivity of the server by inputting the comparing server IP address, number of bundles, and the length of information in bytes. In the wake of handling the inactivity checking parameters, ping measurements of the server and the rough round excursion the reality of the situation will become obvious eventually shown in the outcome. The customer then encodes the solicitation and sends the solicitation to server. AES Algorithm is utilized to play out the encryption and decoding. The server after getting the solicitation needs to unscramble the solicitation utilizing the customer port number and IP address. The server sends the asked for record by encoding the document. At last the customer gets the record, unscrambles the substance and read it. Subsequently it can be inferred that more solid correspondence can be performed amongst server and customers and dynamic interchanges stays unaffected even within the sight of DDoS Attacks

    The automotive industry has been incorporating various technological advancement on top-end versions of the vehicle order to improvise the degree of comfortability as well as enhancing the safer driving system. Infotainment system is one such pivotal system which not only makes the vehicle smart but also offers abundance of information as well as entertainment to the driver and passenger. The capability to offer extensive relay of service through infotainment system is highly dependent on vehicular adhoc network as well as back end support of cloud environment. However, it is know that such legacy system of vehicular adhoc network is also characterized by various problems associated with channel capacity, latency, heterogeneous network processing, and many more. Therefore, this paper offers a comprehensive insight to the research work being carried out towards leveraging the infotainment system in order to obtain the true picture of strength, limitation, and open end problems associated with infotainment system

    WARDOG: Awareness detection watchbog for Botnet infection on the host device

    Botnets constitute nowadays one of the most dangerous security threats worldwide. High volumes of infected machines are controlled by a malicious entity and perform coordinated cyber-attacks. The problem will become even worse in the era of the Internet of Things (IoT) as the number of insecure devices is going to be exponentially increased. This paper presents WARDOG – an awareness and digital forensic system that informs the end-user of the botnet’s infection, exposes the botnet infrastructure, and captures verifiable data that can be utilized in a court of law. The responsible authority gathers all information and automatically generates a unitary documentation for the case. The document contains undisputed forensic information, tracking all involved parties and their role in the attack. The deployed security mechanisms and the overall administration setting ensures non-repudiation of performed actions and enforces accountability. The provided properties are verified through theoretic analysis. In simulated environment, the effectiveness of the proposed solution, in mitigating the botnet operations, is also tested against real attack strategies that have been captured by the FORTHcert honeypots, overcoming state-of-the-art solutions. Moreover, a preliminary version is implemented in real computers and IoT devices, highlighting the low computational/communicational overheads of WARDOG in the field
