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.

How much do health insurance companies spend on executive security? It might be less than you think.
- Health insurance companies appear to spend less on executive protection compared to high-profile CEOs like Mark Zuckerberg or Elon Musk.
- The death of UnitedHealthcare CEO, Brian Thompson, highlights that even executives who aren't as high-profile or famous as others may not always have bodyguards with them.
- The amount companies pay for executive security varies widely, with some CEOs known for having multimillion-dollar security packages while some have more modest protection services worth hundreds of thousands of dollars.
- Walmart CEO Doug McMillon and McDonald's CEO Chris Kempczinski, for example, appear to have individual security expenses of less than $25,000 for 2023, according to company filings.
- Typically, company-paid security costs are disclosed in annual corporate filings called proxy statements, and include a breakdown of the salary, benefits, bonuses, and other perks provided for top executives' total compensation packages.
- UnitedHealth Group appear to allocate less expense on executive protection as some of the Big Tech giants, and don't specify any personal security cost for CEO, Brian Thompson, in last year's filings.
- Other insurance companies, including CVS (owner of Aetna), Cigna, Humana, and Elevance (owner of Anthem), also do not specify personal security costs in their proxy statements, while Kaiser Permanente is a nonprofit and not subject to the same reporting requirements.
- Different executives may have their own personal preference for the level of security they require, which is very much driven on the executives' preference.
- Elon Musk, the world's wealthiest person, has spoken out about personal security concerns in recent years and has more than one bodyguard in his security team.
- Executives at health insurance companies, who may not be as recognizable as someone like Musk or Zuckerberg, may consider reviewing executive protection costs following Thompson's death.
