Free antivirus from Microsoft

Microsoft will launch a free antivirus for PCs – code named Morro – which will be available on the company website. The product, which is found in beta and will compete with products
sold by Symantec and McAfee.

A Microsoft representative announced Wednesday that the software manufacturer is preparing to launch a antivirus, in beta, which can be downloaded free from the company website. Microsoft has stated that the product is still in testing stage and refused to give an exact date for release, stating only that it will take place “soon”.

The danger awaiting behind a screensaver

When we’re talking about your computer security, the most dangerous online activities are searching for screensavers, the lyrics of songs and different stuff for free.
The report prepared by McAfee Inc., a firm specialize in Internet security, looks like hackers know what users search most and using sophisticated search programs , they can [...]

Firewalls | Deploy and Manage

Deploy
Once testing is complete and all issues have been resolved, the next phase of the firewall planning and implementation model is deployment, which should be done in accordance with organization policies.

Before deploying the firewall, administrators should notify users or owners of potentially affected systems of the planned deployment, and instruct them who to notify if they encounter any problems.Any changes required to other equipment, such as changing default routes, should [..]

Overview of Firewall Technologies

Firewalls are devices or programs that control the flow of network traffic between networks or hosts that employ differing security postures. While firewalls are often discussed in the context of Internet connectivity, they may also have applicability in other network environments.

For example, many enterprise networks employ firewalls to restrict connectivity to and from the internal networks used to service more sensitive functions, such as personnel or accounting. An organization [..]

IPv6

IPv6 is a new version of IP that is increasingly being deployed. Although IPv6’s internal format and address length differ from those of IPv4, many other features remain the same—and some of these are relevant to firewalls.

For the features that are the same between IPv4 and IPv6, firewalls should work the same. For example, blocking all inbound and outbound traffic that has not been expressly permitted by the firewall policy [..]

Security – Principles of Authentification

The broadest definition of authentication within computing systems encompasses identity verification, message origin authentication, and message content authentication.
The concept of identity verification specifically applies to principals with information processing and decision making capabilities, including human users, computing systems and processes executing on those systems. From an authentication standpoint, the term “user” applies to all these principals. This guideline focuses on technology and techniques for verifying the identity of human users [..]

Multicast Traffic – Ethernet

Most industrial producer-consumer (or publisher-subscriber) protocols operating over Ethernet, such as EtherNet/IP and Foundation Fieldbus HSE, are IP multicast-based. The first advantage of IP multicasting is network efficiency; by not repeating the data transmission to the multiple destinations, a significant reduction in network load can occur. The second advantage is that the sending host need not be concerned with knowing every IP address of every destination host listening for the [..]

Firewalls Testing

New firewalls should be tested and evaluated before deployment to ensure that they are working properly. Testing should be completed on a test network without connectivity to the production network. This test network should attempt to replicate the production network as faithfully as possible, including the network topology and network traffic that would travel through the firewall. Aspects of the solution to evaluate include the following:

• Connectivity. Users can establish and [..]
