About a fifth of the Fortune 500 was hit by the RSA attacks from earlier this year. A total of 760 companies of all sizes are on the list, with possibly more to be found in the future. It’s disconcerting to note that companies whose primary business is security are on the list. No matter how big or small, companies are constantly under attack. Just because your company doesn’t have valuable assets such as Social Security numbers and banking credentials doesn’t mean attackers will leave you alone. They’ll often attack indiscriminately, gather other sensitive data, take your systems offline, or use your network to launch an attack against someone else.
