But some months are tougher than others.

Security provider Patchlink Corp. believes the release of 12 patches for the month of June, which were released this week, has left IT managers with a "patch management hangover."

The release occurs monthly on the second Tuesday allowing Microsoft to announce product vulnerabilities and issue patches.

Local Patchlink president Neal Gemassmer said the bottom line is that enterprises still face network vulnerability if IT managers fail to get the update fully tested and deployed across the enterprise in a timely manner.

But IT managers who spoke to Computerworld said the bundled releases are more manageable and allow for planning.
