In today's highly digitalized and collaborative business environment, the likelihood of a cybersecurity breach is a matter of when, not if.
Nearly every high-profile breach reported in the news has been a result of a cyberattack that penetrated perimeter security, such as firewalls, anti-virus, authentication, and endpoint detection.
The number of attacks continues to increase-A 2023 report found that three out of four of security leaders witnessed an increase in cyberattacks, with 85% attributing this increase to hackers leveraging generative AI. What Companies Are Doing Wrong.
Enterprises are currently investing in perimeter security solutions, such as MFA, firewalls, and EDR to protect themselves against these cyberattacks, but unfortunately these are not 100% foolproof for sophisticated hackers.
Once hackers bypass these security measures, they can cause significant damage.
The only thing they can control is whether the attacker is able to breach the system and cause damage.
As a result, businesses should proactively prepare with a defense-in-depth strategy rooted in the Zero Trust security model.
To implement a Zero Trust security mindset, organizations need to remove implicit trust and access permissions wherever possible to keep the perimeter well-protected.
It differs from EDR, firewall, and anti-virus defense solutions by automatically assuming a breach has already occurred.
Microsegmentation stops the spread of malware or ransomware after a breach by establishing a micro-perimeter around every asset in the enterprise network and preventing lateral movement.
It allows security teams to define which asset groups should communicate and their purpose in business processes.
Implementing this security strategy is a large project for security leaders to take on.
A CISO's initial priorities when tasked with securing their organization are to implement MFA, firewalls, API security, and email security solutions.
CIOs are focused on business continuity and technology ROI, while CISOs are focused on reducing security risk.
CIOs may have preconceived notions and resistance against implementing complex security measures such as microsegmentation.
This can cause confusion for security leaders due to oversaturation of the market and create a false sense of security for organizations using multiple solutions.
Other companies use circumvented security measures and are waiting for an all-encompassing security solution to solve the burden of microsegmentation adoption.
Security leaders should adopt a defense-in-depth strategy based on a Zero Trust security model.
Incremental network segmentation can help address some of the hesitations with microsegmenation by gradually implementing policies, removing unnecessary privileges, and alerting security teams when there is a breach.
This will prevent further business disruption, financial losses, and reputational damage by isolating systems in the event of a breach.
