Wireless networks and security might be considered an oxymoron. Indeed it is hard to believe in security when it is so easy to access communication media such as wireless radio media. However, the research community in industry and academia has for many years extended wired security mechanisms or developed new security mechanisms and security protocols to sustain this marriage between wireless/…
This chapter introduces the principles of network security monitoring (NSM), which is the collection, analysis, and escalation of indications and warnings to detect and respond to intrusions. NSM is a way to find intruders on your network and do something about them before they damage your enterprise. NSM began as an informal discipline with Todd Heberlein’s development of the Network Securit…
OpenSSL is a popular and effective open source version of SSL/TLS, the most widely used protocol for secure network communications. The only guide available on the subject, Network Security with OpenSSLdetails the challenges in securing network communications, and shows you how to use OpenSSL tools to best meet those challenges. Focused on the practical, this book provides only the information …
Mention the word audit to IT professionals and you will probably sec their eyes glaze over as they imagine frighten visions of auditors with pointy tails, pitchforks, and checklists running around and pointing out all of the things aroung and pointing out all of the things they have done wrong to their manager.
Computer network security is a complex technical issue. Careful research, planning, and implementation is required to ensure that an organization has undertaken "reasonable precaution" with respect to the security of confidential and private electronic information.^ This paper is an introduction to the evolving network security industry. The intent is to provide a current snapshot of this in…
Network security experts agree that well-run corporations need a written security policy. The policy sets appropriate expectations regarding the use and administration of corporate IT assets. However, the conventional w isdom holds that composing and maintaining these documents bog down in a morass of bureaucratic inefficiency and pointless wrangling, which never ends and produces nothing usefu…
Bluetooth is a technology for short range wireless data and realtime two-way voice transfer providing data rates up to 3 Mb/s. It can be used to connect almost any device to another device. Bluetooth-enabled devices, such as mobile phones, headsets, PCs, laptops, printers, mice, and keyboards, are widely used all over the world. Already in 2006, the one billionth Bluetooth device was shipped, a…
Network security is the identification and mitigation of undesirable information flow. Understanding the impacts, ramifications, and options re- quires a basic background in general computer security processes, network theory, and for some protocols, a basic understanding of cryptography. This knowledge can be used both offensively and defensively. Ethics determine whether the knowledge is used…
