You are advised to review security bulletins and advisories from any vendor you use and apply their updates as soon as possible. Many vendors allow you to automate the process of updating their software.
Security updates address vulnerabilities in computer systems that attackers can otherwise use to gain access to systems or information.
A vulnerability is a weakness that can leave a computer and its systems open to attack. Attacks can be carried out in a number of ways, including through malicious software (malware) such as viruses and spyware that can monitor a user's activity on a computer and stop systems operating properly.
