Those whom wish you ill or would gladly steal from you care little about the global economic downturn. They are not sending out fewer exploits as attachments to spam, they have not stopped looking for ways to transfer money from your bank account or use your office PC’s as zombies. When money is tight you need to defend yourself intelligently. Your number one priority should be keeping your software patched. Your second priority should be scanning any externally facing web applications for common vulnerabilities. If you don’t have the skills, hire someone who does. Finally, take the time to educate your employees on safe computing practices. Again, If you lack the skill bring in a professional trainer.
