The definition and importance of Firewall

firA firewall can be either software (computer program or application) or hardware (a special computer that is running a firewall program) which serves to filter the traffic of computer networks and the Internet. Firewall protection is needed, especially for computers connected to the internet connection. Firewall improves the security of computer networks by providing detailed information on network traffic patterns. Firewall is indispensable as a security gateway between the internal networks that is relatively safe with external vulnerable networks (the Internet).

How it works
• All network communications pass through the firewall
• Only the data traffic from a trusted network that is allowed through the firewall
• Firewall has the ability to protect computers from malicious attacks originated from the Internet

Firewall function
The computer has thousands of ports that can be accessed for a variety of purposes. Firewall computer has a duty to close the ports unless some ports that need to be kept open. Firewall in computers also act as a first line of defense in preventing all types of hacking. As we have seen, hackers generally work by trying to break into a computer network through an open port.

In addition, there are also a variety of other uses of the firewall as follows:
• Firewall is useful to maintain confidential and valuable information to keep it out without being noticed by the user. For example, traffic of FTP (File Transfer Protocol) of an organization is generally controlled by the firewall. This is done to prevent users on the network to send confidential file either intentionally or accidentally to any other party.

• Filter of firewall is also used to prevent certain traffic flowing into the subnet network. It is useful to prevent users from sharing music and playing games on the network. This type of application is useful especially in the corporate sector.

• Another important utility of a firewall is to modify the data packets coming through the firewall. This process is called Network Address Translation (NAT). There is a type of NAT called a basic NAT where the private IP (Internet Protocol) address of a computer network is hidden behind one IP address.

Data Recovery – What Technologies You Can Expect to See More of in 2015

Data RecoveryFinancial institutions, retailers and the IT industry as a whole are under growing pressure to have nimble, effective solutions ready in the event of a data disaster. Nobody can prepare fully for every possible issue, so data recovery methods need to evolve constantly to meet demanding objectives.

Today’s technology innovators are looking beyond legacy technologies like RAID and to the future of data recovery in the Internet of Everything. Let’s consider some technologies that are likely to be seen more often in 2015:

Cloud-Based Data Recovery

The cloud has made it possible for just about any company, and even individuals, to have an off-site data storage repository that can be accessed instantly. In 2015, the cloud will become more robust, more common and more secure. That said, IT pros and data recovery centres will still face many challenges when it comes to ensuring that ubiquitous cloud access doesn’t result in a nightmare of unauthorized access to sensitive data.

SSD-Focused Hard Drive Recovery

The performance benefits of SSD hard drives are undeniable. With an average 10 percent faster loading time versus HDD, SSD hard drives help ensure data is loaded and served quickly over long distances. However, for all its benefits, SSD architecture is still prone to data loss. A number of companies, from start-ups to global enterprises, are developing new tools to recover data from afflicted SSD drives.

Data Recovery for Apple-Heavy Environments

In the “Bring Your Own Device” world of the future, the divide between Android and Apple users will become an issue businesses must be prepared for. The majority of data recovery tools out there today are focused on Windows or Linux, but new data recovery hardware for Mac tablets and phones will continue to emerge. This could seriously reduce data recovery costs for home users, too, consult a professional mac repair expert for more information on Apple data recovry if this applies to you.

Secure, Encrypted Flash Drives and Mobile Devices

It was not that long ago when the flash drive was considered one of the most perilous dangers to data security. With increasing speed and capacity, however, a carefully encrypted thumb drive or even a mobile device will become capable of storing entire disk images and ensuring their physical security. Apple’s moves toward integrating on-board biometrics, like fingerprint scanners, will make this more practical as time goes on.

A catastrophe can strike for technical, human or environmental reasons, so be sure to review your own data recovery plans in the new year!
