Security Policy
A policy is a documented high-level plan for organization-wide computer and information security. It provides a framework for making specific decisions, such as which defense mechanisms to use and how to configure services, and is the basis for developing secure programming guidelines and procedures for users and system administrators to follow. Because a security policy is a long-term document, the contents avoid technology-specific issues. Read rest of review…

The world has changed a lot in the last couple of decades. Instead of simply dealing with local or regional concerns, many businesses now have to think about global markets and logistics. Many companies have facilities spread out across the country or around the world, and there is one thing that all of them need: A way to maintain fast, secure and reliable communications wherever their offices are.

You’ve might heard news lately, more people are helping catch burglars, thief, etc by setting up some surveillance tools. Some tools are very simple to install, and off course more cheaper the prices, more peoples wants to get it. And the most important is could operated in a few seconds.

The tools itself are not just a CCTV, or webcam, but also a computer spy. Read rest of review…

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol’s packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user. Much of IP telephony focuses on that challenge. Read rest of review…

About ten years ago, the only way to connect ourselves to internet was using a dial-up connection which had lots of limitations. To begin with, dial-up was not reliable, slow, and often tends to disconnect on the slightest interruption on the line. So, based on today’s standards, the dialup will be disregarded by many users for the above mentioned reasons.
Soon, the invention of splitters and filters paved the way for broadband, the always ‘on’ internet connection. In simple language, broadband refers to a wide range of technologies that offer reliable, high speed internet access. Read rest of review…

Internetworking Protocols
Most of the network protocols currently in use have changed little since the early definitions of the ARPA research and education network when trust was the norm. To have a secure foundation for the critical Internet applications of the future, severe weaknesses must be addressed: lack of encryption to preserve privacy, lack of cryptographic authentication to identify the source of information, and lack of cryptographic checksums to preserve the integrity of data (and the integrity of the packet routing information itself). New internetworking protocols are under development which use cryptography to authenticate the originator of a packet and to protect the integrity and confidentiality of data. Read rest of review…

A vulnerability is a weakness that a person can exploit to accomplish something that is not authorized or intended as legitimate use of a network or system. When a vulnerability is exploited to compromise the security of systems or information on those systems, the result is a security incident. Vulnerabilities may be caused by engineering or design errors, or faulty implementation. Read rest of review…

Intruders’ Technical Knowledge
Intruders are demonstrating increased understanding of network topology, operations, and protocols, resulting in the infrastructure attacks described in the previous section on Internet infrastructure attacks.
Instead of simply exploiting well-known vulnerabilities, intruders examine source code to discover weaknesses in certain programs, such as those used for electronic mail. Much source code is easy to obtain from programmers who make their work freely available on the Internet. Read rest of review…

A network security incident is any network-related activity with negative security implications. This usually means that the activity violates an explicit or implicit security policy (see the section on security policy). Incidents come in all shapes and sizes. They can come from anywhere on the Internet, although some attacks must be launched from specific systems or networks and some require access to special accounts. An intrusion may be a comparatively minor event involving a single site or a major event in which tens of thousands of sites are compromised. (When reading accounts of incidents, note that different groups may use different criteria for determining the bounds of an incident.) Read rest of review…
