Learn about the security-relevant characteristics of operating system data and how it can contribute to improving network security.
- Operating systems play an instrumental role…in delivering network packets.…Operating systems send and receive packets…as their origin and destination…in terms of IP addresses.…Once a network application, say Network Application A,…generates data to be sent to another application,…an operating system, or OS, transforms it…into a packet with headers including information…such as source and destination IPs and port numbers.…
Once the same packet arrives at a destination host…with a target IP, another OS takes over…and removes all the headers and trailers…to extract the data meant to be delivered…to an application expecting to receive it.…The OS then hands it over to the target application.…When this happens, the OS knows which application,…out of the many it hosts, is receiving the data…according to a port number received…from the packet header earlier.…In addition to being an integral part…of the network communications,…OS's are also at the forefront of network defense.…
Attackers constantly probe OS's vulnerabilities…
