Top 5 Cloud Security Threats

There are numerous reasons why businesses today are moving to the cloud.  Some of these include efficiency, accessibility, fast speeds… the list goes on.  It is also thought that the cloud is “safe” from hackers.  The truth is that while it is a secure option, the cloud also introduces a new/different set of security risks.  Hackers have realized that businesses are using the cloud more than ever, so they have adjusted their approach for today’s world.  Many times, hackers take advantage of an organization’s lack of knowledge around cloud security controls.

Below are the top 5 cloud security threats that organizations should still be cautious of –

  1. Data Breaches:
    1. Lack of data value definition & loss impact
    2. Failure to regularly review access to critical or sensitive data
    3. Misconfiguration 
    4. Inadequate encryption methods
    5. Inadequate incident response plan
  2. Insufficient identity, credential, access & key management:
    1. Failure to use strong passwords
    2. Failure to use multi-factor authentication
    3. Inadequately protected credentials
    4. Lack of automated rotation of cryptographic keys, passwords, and certificates
  3. Insecure interfaces & APIs:
    1. Inadequate protection of API keys
    2. Reusage of API keys
    3. Inadequate penetration testing
  1. Account hijacking:
    1. Failure to address the root cause of stolen account credentials
    2. Weak Identity Access Management (IAM) controls
  2. Insider threats (intentional or negligent): 
    1. Poor security education & training for employees/contractors
    2. Failure to regularly audit server configurations

Top 5 Cloud Security Best Practices

As you can see, choosing a cloud hosting provider does not mean your organization is off the hook for ensuring data security.  While hosting providers typically offer several monitoring and alerting services to help prevent a potential security incident, there are still things your organization is responsible for to strengthen your security posture.
