What You Ought To Know About Firewalls

Computers are not merely for typing. Its main purpose nowadays is for internet usage. However, with the amount of online scams and viruses that can affect your hardware, extreme caution is a must before connecting to any internet-related software.

For years, businesses and organizations have used protection from any malware or virus that can affect their businesses’ data. However, the dangerous surge in email spams, Web-borne threats- including viruses, hijacks, malwares and aggressive spywares have forced home computers to acquire the same protection.

Malicious attackers can take all your data and hack all your accounts in minutes. The time of attack is even faster for professional hackers who have higher quality and far more advanced technology. Fraudsters always target PCs for their high bandwidth and always-on nature.

Firewalls do more than protect your computers from malicious ware. They also hide your internet-connect PC from view.

On the latest review of The Peterson Group, one of the leading distributors of mobile phone accessories and laptop peripherals in Taiwan, a large market of hardware-based firewall composes of businesses. In a different study, households with personal computers rarely purchase firewall protection for their PCs at home since it cannot be considered as dangerous with only the members of the family using the connection. For instance, only 3% of the household population in overall Jakarta, Indonesia has firewall installed. This leaves home PCs exposed to all manners of intrusion and attack.

There are two types of firewalls: software applications and hardware devices that plug between your modem and your computer. Although software can be less expensive, a lot of users prefer the hardware since it assures safer connection and better performance.

However, a common misconception happens when an individual purchases a firewall thinking all internet issues will already be solved only to complain later on that he is still receiving spams. Firewalls may be great at stopping unwanted intrusions, but they often do little or nothing to detect virus-laden e-mails or stop intrusive adware and spyware. You'll want separate antivirus and spyware checkers to stymie these threats. What's more, hardware firewalls usually won't manage outbound traffic, which means a piece of spyware can freely send data from your PC to a server on the Internet.

Many experts believe that the dawn of firewall may come one day with all the importance and warnings already laid to the public. It is only a matter of time before people become aware.

The Role of Mobile Phones during Calamity

Mobile use has spread rapidly, especially in some developing countries. Some poor countries are very vulnerable to natural disasters, and many are badly affected when disaster does strike because their infrastructure and emergency response capabilities are often weak.

However though, mobile technology has expanded dramatically around the world. In a review made by The Peterson Group to the Cisco Visual Networking Index, global mobile data traffic has doubled for the fourth year in a row. And looking toward the future, the report estimates that “global mobile data traffic will increase 18-fold between 2011 and 2016.” By the end of that time period, 10 billion mobile devices are projected to be in use around the world.

With its growing usage, this technology is greatly improving disaster relief and public safety efforts. Countries around the world face threats from natural disasters, climate change, civil unrest, terrorist attacks, scams and fraudulent acts, among others. Mobile devices, tablets, and smart phones enable emergency providers and the general public to manage these challenges and mitigate public safety concerns.

On Tuesday, 12th of January 2010, a magnitude of 7.0 earthquake struck Haiti and due to the population density of that area, what unfolds was one of the largest sudden onset emergencies in the Western Hemisphere has ever given. Many lives were lost, homes shattered and families destroyed. People started to give a hand out to help. The government also gave thought of ways to expand the support for the victims. With the help of telecommunication companies, they started a text campaign which every SMS would give a single dollar for the benefit of the Haiti victims. More or less a million dollars were gathered for that cause. Same happened on the aftermath of the tsunami that hit Sumatra, Indonesia, just a few islands away from the country’s capital, Jakarta.

In response to natural disasters such as Hurricane Katrina (2005), the earthquake in Haiti (2010), earthquake and tsunamis in Japan (2011), and the Oklahoma tornados (2013), mobile invention and application have skyrocketed. Mobile development has surged in reaction to the increase in need for instant and accurate information. In Australia, for example, researchers have created software that combines voiceover IP technology with Wi-Fi to enable communication between mobile devices in areas where there is no available reception. Such a feature is of critical importance in cases where traditional communications networks are knocked offline for extended periods of time during or after a major crisis.
