vulnerability assessment

An organization is performing a vulnerability assessment for mitigating threats. James, a pen tester, scanned the organization by building an inventory of the protocols founds on the organization’s machines to detect which ports are attached to services such as an email server, a web server, or a database server. After identifying the services, he selected the vulnerabilities on each machine and started executing only the relevent tests. What is the type of vulnerability assessment solution that James employed in the above scenario?

Investigation of Network Traffic

Leave a Comment / CHFI, Knowledge Base / By

Investigation of Network Traffic in this Network forensics are often defined as sniffing, recording, acquisition, and analysis of the network traffic and event logs so as to research a network security incident. It allows investigator to examine network traffic and logs to spot and locate the attacking system. Devices connected to network still proliferate; computers, smartphones, tablets etc. because the number of attacks against networked systems grow, the importance of network forensics has increased and …

Introduction to TCP and UDP

Leave a Comment / CCNA / By

Introduction to TCP and UDP in the OSI transport layer (Layer 4) defines several functions, the most important of which are error recovery and flow control. Likewise, the TCP/IP transport layer protocols also implement these same sorts of features. Note that both the OSI model and the TCP/IP model call this layer the transport layer. But as was common , when pertaining to the TCP/IP model, the layer name and number are supported OSI, so …

Introduction of OSI Networking Model this blog is written on OSI Networking Model with it’s layer description as well as function and compared OSI with TCP/IP model. OSI Networking Model At one point within the history of the OSI model, many of us thought that OSI would win the battle of the networking models discussed earlier. If that had occurred, rather than running TCP/IP on every computer within the world, those computers would be running …
