Move quickly to secure your systems and fix vulnerabilities that may have caused the breach. The only thing worse than a data breach is multiple data breaches. Take steps so it doesn’t happen again.
- Secure physical areas potentially related to the breach.
Lock them and change access codes, if needed. Ask your forensics
experts and law enforcement when it is reasonable to resume regular
operations.
Mobilize your breach response team right away to prevent additional data loss. The exact steps to take depend on the nature of the breach and the structure of your business.
Assemble a team of experts to conduct a comprehensive breach response.
Depending on the size and nature of your company, they may include
forensics, legal, information security, information technology,
operations, human resources, communications, investor relations, and
management.
- Identify a data forensics team. Consider hiring
independent forensic investigators to help you determine the source and
scope of the breach. They will capture forensic images of affected
systems, collect and analyze evidence, and outline remediation steps.
- Consult with legal counsel. Talk to your legal
counsel. Then, you may consider hiring outside legal counsel with
privacy and data security expertise. They can advise you on federal and
state laws that may be implicated by a breach.
Stop additional data loss. Take all affected
equipment offline immediately — but don’t turn any machines off until
the forensic experts arrive. Closely monitor all entry and exit points,
especially those involved in the breach. If possible, put clean machines
online in place of affected ones. In addition, update credentials and
passwords of authorized users. If a hacker stole credentials, your
system will remain vulnerable until you change those credentials, even
if you’ve removed the hacker’s tools.
Remove improperly posted information from the web.
- Your website: If the data breach involved
personal information improperly posted on your website, immediately
remove it. Be aware that internet search engines store, or “cache,”
information for a period of time. You can contact the search engines to
ensure that they don’t archive personal information posted in error.
- Other websites: Search for your company’s exposed
data to make sure that no other websites have saved a copy. If you find
any, contact those sites and ask them to remove it.
Interview people who discovered the breach.
Also, talk with anyone else who may know about it. If you have a
customer service center, make sure the staff knows where to forward
information that may aid your investigation of the breach. Document your
investigation.
Do not destroy evidence. Don’t destroy any forensic evidence in the course of your investigation and remediation.
