Items related to Network Security Through Data Analysis
Synopsis
System and network administrators have traditionally monitored their systems through general tools such as intrusion detection and logfile analysis. But modern, complex networks, suffering from more and more sophisticated attacks, deserve more analytical tools. Michael Collins, a leading researcher in security, introduces the techniques needed in this book and highlights some of the computing tools that will help catch problems.
The book is divided into three large sections: data collection, analysis, and taking action. These can be iterative, as each discovery alerts the administrator to data that should be collected. Several forms of analysis and visualization are covered. Topics include:
What data to capture on your systems
Data fusion
Structures and storage systems for data
Using R, SiLK, and Python for analysis
Visualization and exploratory data analysis
Graph analysis
Network mapping
Address forensics: determining where traffic originates
Handling malware

Network Security Through Data Analysis: Building Situational Awareness
Falco columbariusWhat's the animal featured on the cover?
The animal on the cover of Network Security Through Data Analysis is a European Merlin (Falco columbarius). There is some debate as to whether the North American and the European/Asian varieties of Merlin are actually different species. Carl Linnaeus was the first to classify the bird in 1758 using a specimen from America, then in 1771 the ornithologist Marmaduke Tunstall assigned a separate taxon to the Eurasian Merlin, calling it Falco aesalon in his work Ornithologica Britannica. Recently, it has been found that there are significant genetic variations between North American and European species of Merlin, supporting the idea that they should be officially classified as distinct species. It is believed that the separation between the two types happened more than a million years ago, and since then the birds have existed completely independently of each other.
The Merlin is more heavily built than most other small falcons and can weigh almost a pound, depending on the time of year. Females are generally larger than males, which is common among raptors. This allows the male and female to hunt different types of prey animals and means that less territory is required to support a mating pair. Merlins normally inhabit open country, such as scrubland, forests, parks, grasslands, and moorland. They prefer areas with low and medium-height vegetation because it allows them to hunt easily and find the abandoned nests that they take on as their own. During the winter, European Merlins are known to roost communally with Hen Harriers, another bird of prey. Breeding occurs in May and June, and pairs are monogamous for the season. The Merlins will often use the empty nests of crows or magpies, but it is also common, especially in the UK, to find Merlins nesting in crevices in cliffs or buildings. Females lay three to six eggs, which hatch after an incubation period of 28 to 32 days. The chicks will be dependent on their parents for up to 4 weeks before starting out on their own. In medieval times, chicks were taken from the nest and hand-reared to be used for hunting. The Book of St. Albans, a handbook of gentleman's pursuits, included Merlins in the "Hawking" section, calling the species, "the falcon for a lady. " Today, they are still trained by falconers for hunting smaller birds, but this practice is declining because of conservation efforts. The most serious threat to Merlins is habitat destruction, especially in their breeding areas. However, since the birds are highly adaptable and have been successful at living in settled areas, their population remains stable around the world.
