Of course, the economic reality is that software engineers are pushed to get their product to market as fast as possible, and security is often a distant priority in the face of budgetary constraints.

Or they could spend arbitrary amounts of time and money patching existing code and take painstaking precaution in writing new software to ensure its security. Software engineers and their customers continuously face a complex and frustrating decision: given a fixed budget, which combination of vulnerability mitigation actions produces optimal system security? In a world without budgetary or temporal constraints, engineers could invest in whatever tools or training they deemed necessary to safeguard applications and networks. Categories and Subject Descriptors D.4.6 : Security and Protection General Terms Security Keywords mobile phone security, malware, AndroidДЄs a software engineer or client, how much of your budget should you spend on software security mitigation for the applications and networks on which you depend? The authors introduce a novel way to optimize a combination of security countermeasures under fixed resources.

These results indicate that security configuration bundled with Android applications provides practical means of detecting malware. Upon close inspection, another five applications asserted dangerous rights, but were within the scope of reasonable functional needs.

In a sam- ple of 311 of the most popular applications downloaded,from the official Android Market, Kirin and our rules found 5 applications that implement,dangerous functionality and therefore should be in- stalled with extreme caution. We use a variant of security requirements engineering tech- niques to perform an in-depth security analysis of Android to pro- duce a set of rules that match malware,characteristics. Kirin certification uses security rules, which are templates designed to conservatively match unde- sirable properties in security configuration bundled with applica- tions.

In this paper, we propose the Kirin security service for An- droid, which performs lightweight certification of applications to mitigate malware,at install time. The increased number,of applications results in a greater chance of installing Trojans and similar mal- ware. However, they will need more operational costs or higher costs to configure and maintain.ABSTRACT Users have begun downloading,an increasingly large number,of mobile phone applications in response to advancements,in hand- sets and wireless networks.

Hybrid networks provide increased flexibility as newer basic topologies can be added while existing ones removed. The concentrated point or the hub can be fixed separately if itвЂ™s not working properly. Problems found in hybrid networks are easier to diagnose because the network hubs or concentration points are small and size compared to the total size of the network. Properly configured hybrid topologies are often easier to expand and scale. Hybrid topologies add more complexity, but also more flexibility to your network. Hybrid technologies can be configured based on your requirements. Transmission line failure can disrupt the network Hybrid Network TopologyДЄ hybrid topology (or hybrid network) is defined as two or more topologies integrated together.One faulty node can destroy the entire network.Adding, removing, or configuring nodes requires the network to be shut down.Makes it easier to detect faults and misconfiguration Disadvantages of Ring Topology.Better performance than bus topology and works under heavy loads.Ring topologies are usually found on school campuses or office buildings. To make a ring network, one usually uses Token Ring, SONET, or FDDI technology. One failed device or cable destroys the loop and can break down the entire network. For larger networks with multiple nodes connected to a ring, repeaters are then used to stop data loss in these transmissions. For one data node to reach another, they have to traverse through all of the intermediate nodes. In-ring topologies, all of the devices are connected in a closed loop configuration. There four main types of network topologies: Network topologies are used to define or describe the arrangement of various types of telecommunication networks вЂ“ such as computer networks, command and control radio networks, and industrial field busses. Disadvantages of Hybrid Topology What is a Network Topology?ДЄ network topology is defined as the layout or arrangement of elements (usually nodes or links) in a communication network.
