Microsoft Windows Access Control

Appropriate Microsoft Windows access controls

The access control of Windows is complex associated with various permission grants. The system assumes that the installation of applications is under Program Files that has a safe default set of permissions. Any application installed in a non-default location goes to C folder. The user can modify the settings to have a Collaborative Access Control List. An administrator should have two accounts one for regular work, and another for administrative work (Homer & Isbell, 2004). The administrator should create user accounts using malware and least privilege where users do not have administrative permissions. An administrator should Continue reading...

Internet Security and Privacy using Cryptography Techniques

This paper attempts to characterize and present some major aspects on Network security and privacy in many sectors or organizations, which could be an issue of growing importance. System Security is the key segment in data security in light of the fact that it is in charge of securing all data passed through arranged machines. System Security mentions to all fittings and programming capacities, attributes, characteristics, operational techniques, responsibility, measures, access control, and managerial and administration approach needed to give a worthy level of security for Hardware, Continue reading...

Communication Security (ComSec)

INTRODUCTION
Communication security is an important section of modern telecommunication systems where signal intelligences and other methods are used to provide secure communication among peers to be connected. Signal intelligence falls into the category of cryptography where the encrypted signal is collected and analyzed for propagating secure communication. This research work will explain the requirements of communication security and will discuss how signal intelligence can be used in communication security. These solutions can be used practically in communication security of the military services.
Signal intelligence is introduced and evolved by military services where signals from foreign communication systems are Continue reading...

The re a number of technologies that are associated with network security defense. Firstly are those technologies that supports wireless sensor network where many features of sensor networks might aid in tackling the challenge of building network that is secure. The unique feature of sensor network might permit fresh defenses that do not actually exist in conventional network. Some of the wireless technologies for network security defense include SPINS, TINYSEC, and LEAP (Singh, Singh & Singh, 2011).
The security protocol for sensor network (SPINS) is a security building block that is optimized for resource limited environments and communication using wireless Continue reading...
