The Security Of The Network - 978 Words

As a distributed system with a number of nodes working together, a Big data cluster relies on the interconnect to communicate between Data Nodes and Name Nodes. The system also needs to extract data from data sources via the network. Thus, the security of the network is critical to the Big data system. The threats relevant to the network include DNS spoofing, eavesdropping attack and Denial-of-Service attacks, Man-In-the-Middle attacks, etc. In the next section, we will focus on two types of network securities and propose the solutions to these issues: One is the security of interconnect, the other is the security of external network connections. III. Security and Privacy Solutions of Big Data As Big data is usually a complex system with Petabytes or more data stored and processed, there is never a single mechanism which can resolve all the security issues. We also need to make a balance between security and cost. In addition, the affect to the performance and usability also need to be taken into consideration. A. Solutions to the unauthorized data access problem The data in Big data system usually contains privacy of many users, therefore it must be protected from malicious from attackers. A commonly used data protection approach is data encryption. A symmetric encryption algorithm is more appropriate than public key algorithm, as symmetric encryption is much faster than the public key encryption. The data needs to be encrypted when it is loaded into the BigShow MoreRelatedNetwork Security And Security774 Words   |  4 Pagesbring the network up to current security standards. Attempts to breach networks are becoming more sophisticated and difficult to defend against, as more powerful hardware is introduced and new security defenses become available leaving older measures unreliable. Aging networks that are improperly secured are more at risk than ever. It is not only important to ensure you have the proper defense at the perimeter but also internally on wired and wireless infrastruct ure.
