There are new vulnerabilities and flaws discovered everyday which could allow a hacker to break your computer security, take control of it for use in a denial-of-service attack or steal or destroy your data security. Keeping your internet security software patched and running updated antivirus software are very important defenses, but having a firewall blocking or regulating incoming connections is definitely a wise idea. No single security solution will solve everything. The more lines of defense you have in place, the harder it is for hackers to get in and the safer you will be.
