Elasticsearch doesn't enforce HTTPS traffic.
Default Severity: critical
Explanation
Plain HTTP is unencrypted and human-readable. This means that if a malicious actor was to eavesdrop on your connection, they would be able to see all of your data flowing back and forth.
You should use HTTPS, which is HTTP over an encrypted (TLS) connection, meaning eavesdroppers cannot read your traffic.
Possible Impact
HTTP traffic can be intercepted and the contents read
Suggested Resolution
Enforce the use of HTTPS for ElasticSearch
Insecure Example
The following example will fail the aws-elastic-search-enforce-https check.
resource "aws_elasticsearch_domain" "bad_example" {
domain_name = "domain-foo"
domain_endpoint_options {
enforce_https = false
}
}
Secure Example
The following example will pass the aws-elastic-search-enforce-https check.
resource "aws_elasticsearch_domain" "good_example" {
domain_name = "domain-foo"
domain_endpoint_options {
enforce_https = true
}
}
