Securing data requires a comprehensive approach to mitigate all possible vulnerabilities.
Areas to make sure to cover are:
SECURITY POLICIES
- password policies: require complex passwords and enforce regular password changes
- data backup and recovery plan:
- data retention policy: this should be reviewed regularly and data retention should be set for different types of data
- access controls: zero trust principle
- Incidence response: define a clear and consice procedure for identifying, reporting (define responsibilities) and responding to security incidents (steps for remediation).
INFRASTRUCTURE
- Operating systems upgrades and updates
- Firewall configuration and maintenance
- Enhancing authentication methods: implement MFA
PHYSICAL MACHINES
- securing physical machines: locking mechanisms, CCTV and access control systems
- remote access: VPN or remote desktop software with authentication controls
LAST BUT NOT LEAST
Always remember, human error is one of the most common vulnerability! Stay informed and train your staff on cybersecurity hygiene!
