Cloud concentration risk occurs when a company relies excessively on a few key cloud suppliers. This dependence raises the possible disruptions caused by a single provider’s failure. With few options, enterprises confront difficulties in reducing this risk while reaping cloud benefits. Potential effects include widespread event impact, high vendor dependence, which limits technological options, and regulatory compliance failures due to varying restrictions.

These strategies can address your cloud concentration risks:

  • Diversify cloud providers: Reduce dependency by distributing risk among several cloud providers and minimize the impact of any single provider’s failure.
  • Implement multi-cloud strategies: Distribute workloads and services over multiple cloud platforms to ensure redundancy and resilience to disruptions.
  • Develop contingency plans: Create carefully planned continuity plans to quickly address large cloud service outages.

Weak Attack Surface Management

Weak attack surface management occurs when vulnerabilities in a system aren’t detected and mitigated properly. It results from a failure to identify, test, and monitor potential access points, such as devices, users, and software flaws. Impacts include increased risk of data breaches, unauthorized access, and cyberattacks as a result of undetected vulnerabilities, which endanger system integrity, privacy, and the overall security posture.

Resolve weak attack surface management through these tips:

  • Adopt zero-trust policies: Limit illegal access by adopting zero-trust security, which ensures that only authorized users can access networks. This lowers entry sites, strengthening the infrastructure against cyber assaults.
  • Streamline networks and tools: Remove unnecessary software, program, and equipment, minimize errors, and reduce the attack surface to prevent unauthorized access to your organization’s data.
  • Conduct vulnerability scans: Run regular network scans to detect and repair any vulnerabilities, ensuring visibility of the attack surface and protecting both cloud and on-premises networks from exploitation.
