In some cases, the threats are worse. In the Middle East, for example, the Palestinians and the Israelis are working hard to break into each others' computers. In these cases, they're looking for secrets and trying to disable computers needed by each others' governments. These break-ins could spread to companies that do business with Palestinian or Israeli customers. Sometimes companies can be targeted by mistake.
Breaches often seem random.
If you protect yourself, such threats might be annoying, but they won't shut down your company. But you must take such threats seriously if you're to contain them. Make sure your company encrypts its credit card file, for example. Make sure you have real, effective and tested intrusion detection. Make sure your firewall and virus scanners are up to date.
