Secure Your Network Using Data Leakage Protection

Data loss prevention (or data leakage protection) involves many methods to prevent data from being lost. Data leakage protection tools can be either hardware or software that protect all types of data in use on a computer network. With the aid of a central management framework, it can also perform intense content inspection Broadcom españa

This tool can perform a context security analysis of transactions that includes detecting attributes such as:

* Originator* Destination

* Data object

* Medium

* Timing

A leakage prevention tool is designed to detect and prevent unauthorised access to data.

Data Leakage Protection Common Tools

These are the basic tools that are used widely in computer networks to secure data transmission:

Firewall: A security device which acts as a barrier between networks. It can accept or deny network access requests. It can also decrypt and encrypt network traffic between different security domains. They are used, depending on the type of software or hardware, to protect internet data and intranets from unauthorised access. To be approved by the firewall, all data that flows through the network must meet certain security criteria.

Routers can be set up to use session encryption on two or more routers within a computer network. Multiple users can view the data flowing over the Internet if they have access to it. Routers encourage protected connectivity between sites. This makes the routes secure.

Virtual Private Networks (VPN): This is a network that provides secure access to a private network to remote offices and individual users who use the Internet or another public telecommunications infrastructure. This is done by adding a logical layer to the larger network.

Network Tap: This allows network administrators to view data passing through a computer network. The technologies used to build computer networks include Ethernet, 802.11, and FDDI. Monitoring the data with a third-party device such as a network tap is crucial.

A network tap must have at least three ports. It can be used for the following:

* VoIP recording

* RMON probes

* network intrusion detection systems

* Pack sniffers

* Network probes

The flow of data and any device connected to the network by a network tap is not affected.

Secure Your Computer and Network With Free Software

You can find almost anything online these days, some for a fee, but most of them free. This is true for firewalls, antivirus software, and adware/spyware blocking programs. These programs keep computers safe from malware and help prevent spybots and trojans from sending our personal data back to their makers. These programs are fine and dandy if you don't mind that they're pretty expensive ($39 a year at McAfee and Norton for basic anti-virus software, the security internet suites can easily run an upwards of $70) and slow your computer down to turtle speed with all the extra addons and 'intrusion-detecting-virus-scanning-database-blocking-popup-alerts-that-annoy-the-hell-out-of-you-and-show-up-for-no-reason' , or you can use free software and achieve some of the best protection you can get for less headache and less cost.

Antivirus programs

avast! is the best antivirus program I recommend. AVG Anti-Virus free Edition v4.7 is also available. Both are compatible with Windows 98 or later, and Vista as well.

Spyware/Adware Removal

Lavasoft's Ad-Aware 2007 Free or Microsoft Windows Defender 1.1 are good options for antispyware protection. Both offer the best spyware and malware detection, and they are very easy to use.

Firewalls

ZoneAlarm Firewall Pro and Comodo Firewall pro are two of my favorite firewalls. ZoneAlarm is easier to use and install, while Comodo Firewall Pro has all the features a power user needs for managing his network and monitoring his firewalls.

Comodo features:

Host Intrusion Prevention System is used to prevent malware from installing and to protect files.

Advanced Network Firewall Engine prevents programs from connecting to internet

A whitelist for nearly one million trusted applications

Comodo Firewall is for people who want the best firewall possible and want to have all options and settings available for a network monitoring application. PC World Australia says that Comodo Firewall performs better than many paid-for alternatives.

ZoneAlarm features

Inbound intrusion detection system

Outbound connections can be made by a variety of programs

Compatible with Windows Vista

Zonealarm is easy to install and use. It won't be noticed unless you have something unusual going on with your firewall. A pop-up window appears in the taskbar when a new program attempts to access the internet. After accepting or denial, you can choose to check a box to stop it asking again.

These programs can all be used to make your computer and network more secure from hackers, intruders and viruses. Each program has its own features and offers different protection levels. Before making a decision, make sure you do your research. You should not have more than one antivirus program or firewall installed on your computer. This can lead to conflicts. You'll do better if you grab more than one of the spyware removers or detectors. They all detect different types of spyware so you will want to ensure you have several good programs.
