Firewalls are among the best-known security tools in use today, and their critical role in information security continues to grow. However, firewalls are most effective when they are backed by effective security planning, a well-designed security policy, and when they work in concert with anti-virus software, intrusion detection systems, and other tools. This book aims to explore firewalls in the context of these other elements, providing readers with a solid, in-depth introduction to firewalls that focuses on both managerial and technical aspects of security. Coverage includes packet filtering, authentication, proxy servers, encryption, bastion hosts, virtual private networks (VPNs), log file maintenance, and intrusion detection systems. The second edition offers updated content and brand new material, from enhanced coverage of non-firewall subjects like information and network security to an all-new section dedicated to intrusion detection in the context of incident response.
In Cybersecurity and Cyberwar: What Everyone Needs to Know�, New York Times bestselling author P. W. Singer and noted cyber expert Allan Friedman team up to provide the kind of deeply informative resource book that has been missing on a crucial issue of twenty-first-century life. Written in a lively, accessible style, filled with engaging stories and illustrative anecdotes, the book is structured around the key question areas of cyberspace and its security: how it all works, why it all matters, and what we can do. Along the way, they take listeners on a tour of the important (and entertaining) issues and characters of cybersecurity, from the "Anonymous" hacker group and the Stuxnet computer virus to the new cyber units of the Chinese and U.S. militaries. Cybersecurity and Cyberwar: What Everyone Needs to Know� is the definitive account on the subject for us all, which comes not a moment too soon.
Ransomware is a plague on the business world. This brief book explains what it is, how to identify it and some precautions you can take to protect your network. It is not meant to be a comprehensive security manual but just the basics on what a business owner or office manager needs to know. Detailed protection planning should then be discussed with the company's IT department or IT provider.
Climate change and cyber-threats exist in two different dimensions; the outer world of the natural environment and the inner world of Cyberspace. Even though they seem very different they are linked through their anthropogenic origins including the detrimental effects they can have on organizations and establishments like critical infrastructures and the populations they serve. Cyberspace and the climate are linked by the man-made threats they face enabling the use of crossover strategies such as employing cybersecurity for the benefit of climate change security. There are several approaches to improving the cybersecurity and climate change security and resiliency in organizations and establishments like critical infrastructures. They are: 1.) Employ a multilayered, defense in-depth approach to security rather than relying on perimeter based security strategies, 2.) Do not rely on faulty policies that only focus on compliance standards, 3.) Avoid corner cutting in training and infrastructure development, 4.) Create incentives such as the Carbon Tax and a cybersecurity incentives framework, 5.) Understand the risks of interacting internal and external dependencies and interdependencies in regards to establishments like critical infrastructures, 6.) Use crossover strategies from kali Linux to test organizations and critical infrastructures for both cyber and climate change security and resiliency, 7.) Devise a cyber-climate collaborative effort of groups of people working towards open communication regarding climate change events and cyber-threats.
People are checking their e-mails, surfing over the Internet, purchasing goods, playing online games, paying bills on the Internet everyday. However, while performing all these tasks, how many people think about security? Do they know the risks of being attacked, infected by malicious software? How many users are aware of that their computer may be used as zombie machines to target other victim systems? As technology is growing rapidly, newer attacks are appearing. Security is a key point to get over all these issues. In this thesis, we will make a real life scenario, using honeypots. Honeypot is a well designed system that attracts hackers into it. By luring the hacker into the system, it is possible to monitor the processes that are started and running. In other words, honeypot is a trap machine which looks like a real system in order to attract the attacker. The aim of the honeypot is analyzing, understanding, watching and tracking hacker’s behaviours in order to create more secure systems. Honeypot is also very useful for future threats to keep track of new attacks.
