5 Patch, Patch, Patch …..

Operating systems and software are made up of numerous components with different functions working in coordination. It is inevitable that some of these components, in some way are less than perfect, these flaws or imperfections – or simply bugs – sometimes result in security issues and vulnerabilities. When a bug or vulnerability leaves a hole in your computer's defenses, it is extremely important to apply the required patch as soon as possible. A patch is designed to update a computer program or its supporting data, to fix or improve it. This includes fixing security vulnerabilities and other bugs, and improving the usability or performance.

• Keep your operating systems and software up-to-date
  
  Operating systems such as Windows, Apple OS X including device firmware/OS such as IOS, Android and Windows mobile need to be updated as soon as bugs or vulnerabilities are discovered and the manufacturer (e.g. Microsoft) has issued a patch for those vulnerabilities.
• Keep all your software/applications up-to-date including device firmware and drivers
  
  Aside from updating your operating system on a regular basis, it is necessary to keep the software/applications that you use with the latest security patches and updates. You should also update the drivers of any device that are linked to your PCs. This will ensure that your computer is up-to-date and will help keep your computer free from viruses and other security threats. Mobile devices (e.g. smart phones and tablets) should also be updated regularly.
  • Example: an Apple IOS security bug published a few weeks ago affected more than 2,500 apps so it is not enough to simply update the IOS, you also have to update the apps to ensure that no security holes are left open
• To simplify updates, turn on automatic updates
  
  Turning on the automatic update feature of your operating system, software and other applications allows you to obtain security patches for identified holes and exploits. This is best accomplished by using built-in automatic update features through the Windows Security Center in latest version of Windows, Automatic Updates control panel in earlier versions of Windows, and the Software Update application in Macintosh OS X under System Properties.
