Passive Visual Fingerprinting of Network Attack Tools


RELATED WORK
The primary contributions of this work include the
demonstration of the efficacy of fingerprinting common
attack tools, the ability to provide rapid insight into the
attacker s operating system type and the possible
lineage of the code in use, the ability to detect some
classes of stealthy attacks and the ability to detect slow
scans despite the visual noise of legitimate traffic

ABSTRACT
PON-based access networks envisage the demonstration of scalability to allow gradual deployment of time and
wavelength multiplexed architectures in a single-platform without changes in fibre infrastructure and also
highly-efficient bandwidth allocation for service provision and upgrade on-demand. This is achieved by the
application of coarse-fine grooming to route reflective-ONUs of time and wavelength PONs collectively and the
development of MAC protocols enabling the OLT to dynamically assign available time slots among ON ....etc

Abstract:
A passive optical network (PON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters utilizing Brewster's angle principles are used to enable a single optical fiber to serve multiple premises, typically 32-128. A PON consists of an optical line terminal (OLT) at the service provider's central office and a number of optical network units (ONUs) near end users. A PON configuration reduces the amount of fiber and central office equipment required compared with point to point architect ....etc

green eld PON networks was deployed to minimize the costs. This technique uses an ef cient heuristic called the Recursive Association and Relocation Algorithm (RARA) to solve the optimization problem. This algorithm can significantly reduce the PON network deployment costs compared to an
intuitive random-cut sectoring approach. The method of cable conduit sharing is proposed to extend to RARA. The studies and analysis shows that there are saturating trends for the PON deployment costs. three system parameters are used viz. optical split r ....etc

Abstract
A Gigabit Ethernet passive optical network (GE-PON)
The GE-PON includes an optical line terminal (OLT), a plurality of optical couplers, and a plurality of optical network units (ONUs). The OLT sets up an active page link and a standby page link in response to a registration request message received over an optical cable. Each of the ONUs is doubly connected with the OLT via the optical cable and is adapted to transmit the registration request message to the OLT, form the active page link with the OLT via the optical cable if it rec ....etc

PON technology



attenuation per unit length
-reasons for energy loss
-copper: resistance, skin effect, radiation, coupling
-fiber: internal scattering, imperfect total internal reflection
.so fiber beats coax by about 2 orders of magnitude
-e.g. 10 dB/km for thin coax at 50MHz, 0.15 dB/km l =1550nm fiber

Access network bottleneck

.local area networks
use copper cable
get high datarates over short distances
.core networks
use fiber optics

Ethernet passive optical networks (EPON) are an emerging access network technology that provides a low-cost method of deploying optical access lines between a carrier's central office (CO) and a customer site. EPONs build on the International Telecommunications Union (ITU) standard G.983 for asynchronous transfer mode PONs (APON) and seek to bring to life the dream of a full-services access network (FSAN) that delivers converged data, video, and voice over a single optical access system.
The communications industry is on the cusp of a revolut ....etc
