On holiday: Most important policies for reduced staff
- December is prime time for cyberattacks and data leaks, especially in the United States, where organizations and employees are in holiday-season mode between Thanksgiving and New Year’s.
- Threat actors know this and see this period as prime time to launch an attack.
- Of the 18 cybersecurity professionals approached, only two shut down operations completely, while several reduced the number of staff working or were more flexible with providing time off.
- Keeping cybersecurity standards at normal levels is vital for all of the organizations.
- Several respondents stressed that cybersecurity standards have to be kept at normal levels, often through increased automation in threat detection or enhanced monitoring.
- Half the organizations freeze updates and patches, six change their incident response plan and elevate their alert protocols and four limit account access.
- 'The attacker was trying to encrypt critical data, which required immediate action from the response team. Due to proactive measures and rapid response from our offshore team, we managed to control the attack surface.'
- The common thread with these stories is that each security professional had either a plan in place that resulted in minimal damage or was able to use the incident to prevent problems in the future.
- To learn how IBM X-Force can help you with anything regarding cybersecurity including incident response, threat intelligence, or offensive security services schedule a meeting here.
- If you are experiencing cybersecurity issues or an incident, contact X-Force to help: US hotline 1-888-241-9812 | Global hotline (+001) 312-212-8034.
