This sort of news certainly doesn't come around as frequently or on a strict schedule, but it is nonetheless just as important as (for example) Microsoft's well known "Patch Tuesdays." On Tuesday, March 18th, Apple released a comprehensive security update for Mac OS X 10.4.11 and Mac OS X 10.5.2, as well as a security update package for its Safari Web browser. Apple doesn't follow the same monthly release schedule as their best competitor, but that doesn't affect the importance of such a security update.Since the release of these security updates, we have come across all kinds of news feeds and blogs that refer to it as a patch release. Those writers calling it a "patch release" has of course raised the ire of users and readers alike, with arguments ranging from the size of the downloads to comparisons with Microsoft or Linux updates. Some people have referred to it as a software upgrade, but we must call for calm in the industry. :-) Instead of bemoaning the size of download or making the inevitable comparisons with other OS vendors and their patch release schedules, we should embrace the security benefits that have surely been addressed with this update.As Apple increases its market share, it will be of extreme importance to be one step ahead of problems and by releasing this security update for at least 95 security holes in the Mac OS X operating system and the system's open-source components, Apple will be looking to mend as many holes as possible, before they become vulnerabilities. Take a closer look at Apple's advisory on the details of the update, found here. As always, Symantec recommends that you assert responsibility for the security of your computer by keeping your antivirus and firewall software and definitions up to date. In addition, this latest advisory serves as a perfect reminder to ensure that your operating system (no matter what vendor) is fully patched, upgraded to a new version, or has security update applied. No matter what your definition of the care for the OS is, it won't hurt to keep things current. Oh, and be careful out there.
