The bottom line is it seems like if you have defenses in against the LSASS exploit, youre set against the best todays malwarriors have to throw at you. You can take off early for a supersized Memorial Day weekend (thats an American thing for those of you abroad), or you can take the opportunity to tighten your defenses.

Lots of skeleton crews in place.In the meantime, time to test and install operating-system patches and firmware upgrades youve been putting off.

Time to do one more check through your firewall policies, for old accounts that dont need to be there, for old services related to software that isnt running anymore.

Make sure theres some way to know if an attack begins when youre vulnerable over the weekend, so at least you can shut things down. Translation: Bring your BlackBerry out to the beach with you.
