Storage security threats
Securing SAN environments has become an increasingly important aspect of data security. IT
organizations face many security threats and must comply with numerous industry and government
regulations. In the past, IT organizations accepted that authentication issues were handled by the
network architecture; they were not responsible for SAN security.
The NSA IATF defines five security attack classes that you should consider when defining your solution
(Table 193).
Table 193 Security attack classes
DescriptionAttack class
Attacks that can disclose information to an attacker.
Passive attacks include:
• Analyzing traffic
• Monitoring unprotected communications
• Decrypting weakly encrypted traffic
• Capturing authentication information (passwords)
An example of a passive attack is the disclosure of information such as credit card numbers
and passwords.
Passive
Attacks that can disclose information, deny service, or modify data.
Active attacks include:
• Attempting to circumvent or break protection features
• Introducing malicious code
• Stealing or modifying information
• Attacking a network backbone
• Exploiting in-transit information
• Penetrating an enclave
• Attacking when a remote user attempts to connect to an enclave
