Internet Scanning The internet is vast, and there are many vulnerabilities that can be exploited by attackers. To defend the internet, we need to map it efficiently. One way to do this is through internet-wide security scanning. By exposing vulnerabilities and tracking the adoption of defensive mechanisms, we can better protect the internet. Zmap is an open-source scanner designed to scan the entire internet. It is efficient and is able to scan the entire IPv4 address range within an hour....

Botnet Detection: Understanding the Need, Techniques, and Challenges Botnets are a coordinated group of malware instances that are controlled via command and control (C&C). They can perform multiple kinds of activities, making them difficult to detect using traditional security measures. In this article, we’ll explore the need for botnet detection, techniques used for botnet detection in enterprise networks and on the internet, and the challenges associated with botnet detection. The Need for Botnet Detection The goal of network monitoring is to detect and prevent attack traffic....

Cloud Computing Cloud computing is a model for enabling rapid provisioning of resources from a pool of resources. There are three cloud service models: Software as a Service (SAAS), Platform as a Service (PAAS), and Infrastructure as a Service (IAAS). SAAS allows users to use the provider’s application, while PAAS allows users to use the provider’s platform to build applications. IAAS allows users to use the provider’s fundamental computing building blocks like compute, storage, and networking....
