In order to protect data, one has to be aware of the possible threats. People often focus solely on malicious attacks from foreign networks. A comprehensive security concept needs to consider many other aspects. Following is a list of possible points of weakness:
There are many statistics showing that malicious attacks from the outside are only a smaller fraction of all the possible risks. Many threats come from within the internal network and can in many cases be related to human misconduct or faulty administration. Many of these risks cannot be controlled by technical mechanisms.

Although momentum is building for a standardized protocol for instant messaging, interoperability among IM applications continues to be vexed by unresolved business and security issues. Recently, the Internet Engineering Task Force (IETF)-sponsored protocol that would be a key to interoperability was criticized for being insecure by IM software vendors such as AOL Time Warner Inc. and IBM’s Lotus Software. The Lotus-AOL test used a variation of Simple Implementation Protocol (SIP) known as SIP for Instant Messaging ...
2. Detecting Unauthorized 802.11 Cards and Access Points
The first goal is detection. Can we tell when someone powers on a card within range of the local network? This can be done with off-the-shelf components and free software. The Cisco Aironet driver included with the more recent Linux kernels supports "RF Monitor" mode, which permits promiscuous monitoring of 802.11 packets - specifically, monitoring raw 802.11 frames to detect if there are any telltale frames broadcast by a rogue access point or card. As outlined in the original 802.11 specification, ther...
3. The HTTP Request and Response Codes
The HTTP protocol can be likened to a conversation based on a series of questions and answers, which we refer to respectively as HTTP requests and HTTP responses. The contents of HTTP requests and responses are easy to read and understand, being near to plain English in their syntax. This section examines the structure of these requests and responses, along with a few examples of the sorts of data they may contain. The HTTP Request After opening a connection to the intended serv...
4. INFRASTRUCTURE PROTOCOLS AND APPLICATIONS
H.323 H.323 defines packet standards for terminal equipment and services for multimedia communications over local and wide area networks communicating with systems connected to telephony networks such as ISDN. The initial version of this standard came from the International Telecommunications Union (ITU) in June 1996. It defines communication over IP-based local area networks (LANs). A later version (v2), adopted in January 1998, extended it over wide are...
The IN protocols and concepts can be used to implement enhanced wireless services rapidly and to have these services available across serving areas in an untethered wireless network. Some of these services are listed below: Voice-Based User Identification. This service employs a form of automatic speech recognition to validate the identity of the speaker. Access to services can then be restricted to the user whose voice (phrase) has been used to train the recognition device. Voice-Based Featur...
6. Wireless LAN and Personal Area Network
The Wireless Internet is not just wireless communications across town or the country. It is also local—sometimes in a home or office building. Wireless LANs are just becoming popular with economically priced wireless Ethernet equipment. Standards such as IEEE 802.11, HiperLAN2, and Home RF are leading the way to untethered communications in-building or outside over small areas. Another important development is the Personal Area Network, also known as Bluetooth. Let’s take a look at each of th...
7. The Domain Concept
The solution to all of these problems is the network domain. In a domain, you only have a single name and password, which gets you into every shared PC and printer on the network. Everyone's account information resides on a central computer called a domain controllera computer so important, it's usually locked away in a closet or a data-center room. A domain controller keeps track of who is allowed to log on, who is logged on, and what each person is allowed to do on the network. When you log onto the domain with your PC,...
