The internet considered a tool that effectively ensures communication globally has been hindered by hackers and crackers continuously. In so doing, a multitude of network facilitated tools such as firewalls, virtual private networks (VPN) and a variety of antivirus software packages has been enabled for dealing with such predicaments. However, more often than not these facilitated tools are mar...

To curb the impact and transmission of worms and virus for simple mass action incidence rate in computer networks, SI1I2RS (Susceptible, Infectious due to worm, Infectious due to virus, Recovered and Susceptible) model have been formed. Basic reproduction number, endemic equilibrium state and their stability are discussed for the simple mass action incidence. For locally and globally asymptotic...

An exhaustive literature survey on the secondary metabolites of widely distributed Prunella vulgaris L. species has been carried out. Triterpenoids, sterols, phenylpropanoids, flavonoids, coumarins, fatty acids, volatile oils and carbohydrates along with some other compounds, have been reported from this species. Many of these compounds have been found to possess significant biological properti...

As an important physiological active factor in the body, lysozyme has a variety of functions, such as bacteriostasis, antivirus and immunity enhancement. This paper describes detail application food processing fields storing meats, prevention deterioration alcoholic drinks, fruits vegetables, treatment microbial infectious diseases, cancer, virus infection other medical fields. At same time, pr...

By incorporating the time delay due to the period that computers use antivirus software to clean the virus into the SLBRS model a delayed SLBRS computer virus model is proposed in this paper. The dynamical behaviors which include local stability and Hopf bifurcation are investigated by regarding the delay as bifurcating parameter. Specially, direction and stability of the Hopf bifurcation are d...

Attacks against networked system are common and increasing, therefore, IT practitioners need to secure the system. Hence, security is recognized as a key feature for sharing data among enterprises and the semantic web. Sharing increases the risk like viruses, fraud, and misuse of data. Data can be secured internally by a secured product and secure settings, as well as externally by using encryp...

How does software break? How do attackers make software break on purpose? Why are firewalls, intrusion detection systems, and antivirus software not keeping out the bad guys? What tools can be used to break software? This book provides the answers. Exploiting Software is loaded with examples of real attacks, attack patterns, tools, and techniques used by bad guys to break software. If you want ...
