The recent Twitter data leak of 2.8 billion users' personal information highlights insider threats due to disgruntled employees retaining access to sensitive systems.
Proper identity hygiene is crucial, with dormant 'zombie' accounts posing risks as a common attack vector for cybercriminals, as highlighted in the Verizon Data Breach Investigations Report 2024.
Mitigating risks includes promptly revoking access for departing employees and implementing identity governance automation solutions to minimize errors and reduce deprovisioning time.
Maintaining a risk-aware mindset is essential, as insider threats can lead to compliance liabilities and severe consequences, emphasizing the importance of managing cybersecurity risks effectively.
