In 2009 was released a report stating that if you connect to the Internet with a computer without security updates or without other protections , the system is infected within four minutes. This announcement seems to be very afraid, but do not worry : is totally unfounded.
More is not that a news released on purpose to create confusion and panic unjustified, and a marketing tool used by the organization that issued it ( in this case, SANS , a company that sells security training courses and organizes conferences ) .
It ‘ true that there are many malicious programs that automatically search and on the Internet to infect unprotected machines , but it is true that they are easily infected . If you install anything prior to Windows XP SP (which was released in late 2004) , perhaps you should worry about , unless there is something on your network that you ‘re put under protection , which is probably true , you know it or not.
Your ISP (Internet service provider) is probably already preventing unwanted traffic from the Internet to achieve your devices . Your wireless router or your cable modem / DSL could carry a firewall enabled by default and your router / modem most likely will use NAT ( network address translation ) . NAT technology protects you from external threats , even if your car turns in a very old version of Windows.
These technologies make it extremely difficult for someone from outside can penetrate into your machine without you yourself do something. This usually means that only you can be the cause of infection . You could visit a site that tries to deceive you to download something dangerous or you receive an email that tries to exploit the vulnerabilities of the program used for electronic mail, or you try to install something .
In any case , it is you who started a connection to the outside. Clearly there are many prevention techniques that can keep your machine safe. Why , then , SANS should spread things that seem true? SANS measurement data certainly real , but fluctuates . SANS says nothing about the methodology used to calculate these numbers. Although it is a good listen to those who provide valuable safety tips , do not believe too whistle alarms for the sole purpose of terrorizing people . In essence, do not believe campaigns Marketing is not supported by strong evidence
