Practical Network Scanning

By: Ajay Singh Chauhan

Overview of this book

Network scanning is the process of assessing a network to identify an active host network; same methods can be used by an attacker or network administrator for security assessment. This procedure plays a vital role in risk assessment programs or while preparing a security plan for your organization. Practical Network Scanning starts with the concept of network scanning and how organizations can benefit from it. Then, going forward, we delve into the different scanning steps, such as service detection, firewall detection, TCP/IP port detection, and OS detection. We also implement these concepts using a few of the most prominent tools on the market, such as Nessus and Nmap. In the concluding chapters, we prepare a complete vulnerability assessment plan for your organization. By the end of this book, you will have hands-on experience in performing network scanning using different tools and in choosing the best tools for your system.

Security approach for cloud computing


From on-premises to the cloud application transformation journey, consumers have lost visibility on many things. Network security does not offer consumers the visibility required for highly virtualized cloud networks. Cloud technology comes with a certain degree of uncertainty and fear. Relying on cloud to store large amounts of critical data with no network boundaries, less visibility and reduced security control, makes it difficult for administrators to see what's happening with applications and data. 

Cloud revolves around data centers and its global presence. Consumers have a lack of visibility into underlying networks and the security infrastructure of a cloud provider. The biggest question for all cloud consumers is whether you are supposed to know about underlying cloud infrastructure builds. The answer to this would be yes and no. The answer would be no with regards to underlying network and security for underlying base infrastructure since you...
