Criminals and hackers are always looking to exploit holes within software to gain access to your computing devices. One method they use is to look for vulnerabilities within software code to target their attacks. Once these vulnerabilities are discovered, software providers rewrite or update their software code to "patch" the holes so they cannot be exploited. In 2015 over 100 patch bulletins were issued.
