Types of Networks
Week7 Part4-IS
RevisionSu2013
Types of Networks
There are different types of networks. Each type has different characteristics and
therefore different security needs. Some of the fundamental differentiating attributes of
the various types of networks are:
the physical distance the network spans
the topology of the network nodes
the types of media used for communication between nodes in the network
the different devices supported on the network
the different applications supported on the network
the different groups of users permitted on the network
the different protocols supported on each network
Depending on the type of network there may be different information security
requirements requiring that various protocols, security services, security mechanisms are
used in a fashion to support that type of network.
While each network environment has some characteristics and security needs unique to
that environment, there are many security techniques that should be universally applied to
all environments. For example; sound policies and procedures, risk assessment of the
assets, user awareness training, encryption technology, authentication technology, sound
credential (password) selection and protection, malware protection, firewalls are a few
security techniques that need to be applied in all of the networks albeit in configurations
that best suits a particular environment.
Local Area Network (LAN)
A LAN network covers a small geographic area that takes advantage of high speed data
transfers usually implemented through Ethernet or fiber. A LAN could be a home, office,
group of building with local proximity (university, business). LANs typically share
resources such as file servers and printers.
Wide Area Network (WAN)
A WAN covers a large geographic area that may require connection through satellite,
high speed dedicated lines and other means. The internet is a WAN. WANs can connect
LANs together into a larger organizational structure that can be used to share resources
such as file, email, dns servers to name a few. Resources can be shared using slower
connections on geographically separated areas across the WAN.
Wireless Networks and Mobile Networks
The movement to laptop systems at home and workplaces accelerated the mobility of
computing.
As employees traveled between offices, client sites, home and various other remote
locations they could remain connected to company servers as long as the remote site had
connectivity to the companies’ intranet. Initially this connectivity was provided by
having Ethernet cabling available for remote users to physically plug their laptops into.
Eventually, companies started installing wireless hotspots that could be automatically
detected by systems that had wireless cards.
The proliferation of wireless connectivity and internet use spread from the workplace to
genera ...

This document proposes using Software Defined Networking (SDN) to improve security in Internet of Things (IoT) networks. It discusses how SDN allows centralized control and programmability that can be used to implement security applications and dynamically enforce security policies. The document presents a framework that uses an SDN controller and edge node running virtual machines. It collects network flow data and uses an anomaly detection algorithm to identify malicious flows based on variance from expected values. When anomalies are detected, security policies are applied through the SDN controller to mitigate the threats, such as rate limiting or blocking malicious traffic flows. Simulation results show the effectiveness of the anomaly detection algorithm improves as the time window size increases.

This document proposes using Software Defined Networking (SDN) to improve security in Internet of Things (IoT) networks. It discusses how SDN allows centralized control and programmability that can be used to implement security applications and dynamically enforce security policies. The document presents a framework that uses an SDN controller and edge node running virtual machines. It collects network flow data and uses an anomaly detection algorithm to identify malicious flows based on variance from expected values. When anomalies are detected, security policies are applied through the SDN controller to mitigate the threats, such as rate limiting or blocking malicious traffic flows. Simulation results show the effectiveness of the anomaly detection algorithm improves as the time window size increases.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
