The Juniper SRX Services Gateway VPN must use AES encryption for the IPsec proposal to protect the confidentiality of remote access sessions.
High Severity
<VulnDiscussion>Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. The Advance Encryption Standard (AES) encryption is critical to ensuring the privacy of the IPsec session; it is imperative that AES is used for encryption operations. Remote access is access to DoD-non-public information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network. Remote access methods include broadband and wireless connections. While there is much debate about the security and performance of AES, there is a consensus that AES is significantly more secure than other algorithms currently supported by IPsec implementations. AES is available in three key sizes: 128, 192, and 256 bits, versus the 56 bit DES. Therefore, there are approximately 1021 times more AES 128-bit keys than DES 56-bit keys. In addition, AES uses a block size of 128 bits—twice the size of DES or 3DES.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
