Techopedia Explains Storage Area Network Security

SAN security generally requires first analyzing the underlying SAN infrastructure for possible loopholes and/or vulnerabilities.

Some of the techniques used for securing a SAN infrastructure include:

  • Encrypting data at rest when stored on a SAN infrastructure or storage drives
  • Isolating users/departments/organizations using a virtual SAN
  • Securing network and communication interfaces
  • Implementing an access control list (ACL) and digital certificates within the switch to ensure only authenticated switches join a SAN fabric
  • Removing and resolving single points of failure
  • Mitigating network-based vulnerabilities such as Simple Network Management Protocol (SNMP), which is vulnerable to Denial of Service (DoS) attack

SAN security may also involve creating and implementing a SAN backup and recovery plan to ensure it stays operational even after an attack or threatening incident.
