IPsec Phase 1 and Phase 2 authentication algorithms default to SHA-1.
Security is not as good as it could be.
When creating a 'net ipsec ipsec-policy' or creating a 'net ipsec ike-peer' and taking the defaults.
Configure a higher level of security. e.g. SHA-256, SHA-384, or SHA-512.
IPsec Phase 1 and Phase 2 authentication algorithms now defaults to SHA-256.
