How does a VSAT network work? A VSAT network has three components: • A central hub (also called a master earth station) • The satellite • A virtually unlimited number of VSAT earth stations in various locations - across a country or continent Content originates at the hub‚ which features a very large -15 to 36-foot (4‚5 -11m)- antenna. The hub controls the network through a network management system (NMS) server‚ which allows a network operator to monitor and control all components

Case Study: Industry Sector: Configuration Review – Firewalls & Routers Media and Telecommunications Firewalls aim to provide organisations with reliable security at the network perimeter; however each firewall must be properly configured in order to allow and disallow network traffic accordingly‚ in a manner sensitive to business needs. Poorly configured firewalls can be overwhelmingly damaging to the security of an organisation – lax ingress rules may provide multiple vectors to attackers

ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest for designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers INTRODUCTION Over the past few years‚ Internet-enabled business‚ or e-business‚ has drastically improved efficiency and revenue growth. E-business applications such as e-commerce‚ supply-chain management‚ and remote

Q2. Given ChoicePoint’s experience‚ what is the likely action of similar companies whose records are compromised in this way? This crime is an example of a failure of authentication‚ not network break-in. ChoicePoints’s firewalls and other safeguards were not overcome or harmed. To avoid such problems in the future‚ the likely action that should be taken by the similar companies is to applying more authentication methods. For example by using a unique user name and determines that the person is

Network security concepts Network security starts with authenticating‚ commonly with a username and a password. Since this requires just one detail authenticating the user name —i.e. the password— this is sometimes termed one-factor authentication. With two-factor authentication‚ something the user ’has’ is also used (e.g. a security token or ’dongle’‚ an ATM card‚ or a mobile phone); and with three-factor authentication‚ something the user ’is’ is also used (e.g. a fingerprint or retinal scan)

Attacks on layer two of the OSI model Seven layers of OSI In 1977 a model called Open Systems Interconnection (OSI) was proposed‚ with the aim to establish an interoperability standard for different vendor products. This model defines several layers related to data transfer‚ from the lowest (physical) to the highest (application) layer. They have a strong dependence upon one another and headers are usually added when traversing from a lower layer to a higher one. The seven layers are: Layer 1 -

Introduction: Computer and network security is a new and fast moving Technology and as such‚ is still being defined and most probably will always be “still defined”. Security incidents are rising at an alarming rate every year [Figure - 1]. As the complexity of the threats increases‚ so do the security measures required to protect networks. Data center
