Cybersecurity best practice – minimum controls for professional services firms
In response to this heightened risk landscape, leading experts in both insurance and risk management argue that investing in robust cybersecurity measures is not a luxury, but a strategic necessity. The cost of a cyber breach, both in financial and reputational terms, far outweighs the initial investment required to fortify digital perimeters.
As such, certain cyber hygiene standards which were merely recommended a few years ago are now considered mandatory across the board. Before they are willing to offer a quotation, insurers will undertake an in-depth assessment of a firm’s cybersecurity infrastructure to ensure minimum cybersecurity controls are in place. Such controls include:
- Multi-factor authentication (MFA) – this is the first control an underwriter will look for and remains the first hurdle to securing cover. Remote network access, admin accounts, third-party remote access, and email user accounts. However, MFA alone will not be enough to meet insurers’ minimum standards
- Endpoint detection and response (for the smaller entities anti-virus and firewalls which are updated at least quarterly)
- Data backups – ensure backup integrity (including encryption, air-gapping, secure (preferably offline) platforms, appropriately tested restoration) conducted on a weekly basis and held offline or offsite
- Training – ensure all staff awareness cyber training including regular phishing simulations, protocol re safe use of portable devices, limited use of public Wi-Fi, and security controls for videoconferencing on an annual basis
- End of life systems – segregated from the rest of the network
- High severity patches – all critical patches implemented within 30 days
- Email filtering software to scan incoming emails for malicious links or attachments
- Passwords – ensure appropriate password management software with strong passwords required for admin rights.
There are also preventative and detective controls which are important and should be considered. These include:
- Privileged access management software – ensure strategies and technologies are in place to control privilege
- Business continuity plan – ensure a BCP is in place which addresses network outages, off-line communications, and data recovery protocols
- Monitoring capabilities – either through an SIEM or an internal team that is alerted on a 24/7 basis of any suspicious activity.
All insurers have different appetites and market strategies, so it is not one size fits all; however, the above controls provide a set of standards and are deemed good business practice to have in place.
Firms should not be daunted by the above list, but rather take this as a positive opportunity to understand what controls they currently have, and what they may need to implement to improve their security. To satisfy cyber insurers, it’s important that firms instil a culture of cybersecurity awareness at every level of their organisational hierarchy.
Resilient cybersecurity infrastructures are less likely to be compromised by cyber risks. As cyber exposures have increased in recent years, so have premiums.
Accordingly, establishing a resilient cybersecurity infrastructure is the best and only method for reducing cyber insurance premiums.
Conclusion
Unfortunately, the cyber risk landscape for professional services is not a distant storm on the horizon, it’s a current reality, and the ever-evolving threat remains a challenge that all firms must meet. The implementation of a robust cyber risk management plan helps to mitigate risks, protect your balance sheet, preserve your reputation, and facilitate growth within your firm.
