Look Where the Future of Internet Security is Heading to…

Hackers are getting more sophisticated and it has become tough for businesses to survive their attacks. Today, internet means a lot, rather everything to us. Things are changing at a faster rate and so will the internet. Consequently, the new interfaces will bring in unique security challenges. On the other hand, there will be a major shift in the devices used for surfing the internet. The future locality of internet connections would no longer be restricted to businesses; it will be embedded into cars, everyday appliances, clothing, and even disposable packaging. It’s going to be everywhere, making security more challenging than ever. internet-security

Thinking of the wildest guesses as to how the internet will grow, our focus should now be directed at thinking about how it can be safeguarded in the future.
Some of the precise questions to be seriously thought upon are: How important will then security be? What will it cost – as an individual & an organization? What will the unseen threats look like? How will we defend against their attacks? Let us first look at the existing elements of the internet network security. Five elements of internet security are practiced today – Architectural, Technological, Psychosociological, Procedural and Existential elements. But the question remains – Will this state of affairs last?

Though simple, internet-based attacks will prevail and some hackers will continue using the traditional means of attack, the huge leap of technological transformations invites the need of precise and advanced security procedures. Many of the common characteristics will be transcended by tomorrow’s attacks and most of them will:

  • Be untraceable
  • Survive on the Net as self-multiplying software entities
  • Not be controllable or stoppable
  • Have no discrete beginning or end
  • Persist for years, even decades, in a longitudinal attack

The ultimate problem persists – how are we going to deal with these? How will we defend against the threats and secure the data that is most important to us? Active search has already been initiated by major organizations and if they perform well on board, the networks themselves may help to improve their own immune systems. Then, destiny would be survival of the fittest networks.To avail their Internet Security,visit http://www.netactivity.us/contact.html or call Harry Bhatia at 2165035150 X 206.

Key Role of Firewalls In Network Security : How It Works?

Firewalls & network security services are known to all those who use the internet and stands important as a protective shield to your network. Today, internet is a basic necessity of computer (or any digital media) users. However, it also invites invader’s attack on the network security which can lead to build up a malicious traffic on your system by encouraging unauthorized access to and from a network.

How does a firewall network security plan works:

A firewall is responsible for bringing in only safe and relevant traffic to your private network or computer system. It keeps a check on any unauthorized access to your computer and automatically refuses and decrypt’s unwanted information through the network.

It uses one or a combination of the following three methods to monitor traffic flowing in and out of the network.

Packet Filtering

This is the earliest and very basic type of firewall protection that inspects packets of information and flags inappropriate content or suspicious files. It uses a pre-defined set of rules to detect the packet’s source and destination address, protocol, and destination port number.Although the transport layer is used to obtain the source and destination port numbers, the packet filter firewalls mainly work on the first three layers of the OSI reference model.

Stateful Inspection

Introduced in 1994, the Stateful Packet Inspection provided additional information about the origin of a packet – whether it is a part of an existing connection or not. This eventually led to speeding up of packet processing. Stateful firewalls, without further analysis, allow packets that are part of an existing connection and evaluate others according to the rules set for new connections.

Application Filtering

With the increasing web server attacks, application-layer firewalls emerged in 1999 to protect servers as well as the applications. This enabled the firewalls to filter packets on any OSI layer up to the application layer. The advantage of application layer filtering is that it lets you block specific content like malware or certain websites and recognize when certain protocols such as HTTP, FTP & DNS are being misused.

Proxy Service

It acts as an intermediary between systems. The proxy firewall prevents establishing direct connections between both the sides; they are forced to conduct a session through the proxy, which can block or allow traffic according to the pre-defined set of rules.

Firewalls are an inseparable part of the packages provided by managed IT support services providers (MSSPs). Net Activity, Inc. a leading provider of internet security services, Cleveland includes firewall security as a service with management of threats from the network operational center.
