So you think your computer or network security has been breached. What next?
Your computer support staff may have brought this to your attention already, but if not you need to make them aware as quickly as possible. Avoid the obvious urge to wipe the hard drives and start over! You need to preserve the compromised computers or servers for a forensic analysis. This is work that is best performed by a qualified computer security or forensics professional.
Signs that you may have sustained an attack:
- Viruses, spyware, malware, and Trojan horses appear on your computer.
- Clicking on a link on a SPAM or phishing email could send you to an infected web site or trick you into revealing personal or financial information or login credentials.
- Unusual charges on your credit cards, bank accounts, or changes to your credit report could indicate identity theft.
The United States Computer Emergency Readiness Team (US-CERT) maintains an incident reporting system for computer security incidents. There are additional suggestions on the StaySafeOnline.org web site.Share
