Our security groups are administered at https://console.aws.amazon.com/ec2/v2/home?region=us-east-1#SecurityGroups:.
A security group allows certain IP addresses to connect a machine, once the machine has been added to the security group like this:
aws ec2 modify-instance-attribute --instance-id THE_MACHINE_S_INSTANCE_ID --groups LIST_OF_GROUPS --profile security
They’re added by Ansible to new servers using the AWS key pair security_access_key / security_secret_key
which are in the group_vars/vault file.
Security Group | Description | Ports | Details | Admin |
|---|---|---|---|---|
| worldwide ssh access |
22
The production and staging ArchivesSpace servers need this group to allow developers to ssh to them. This allows worldwide ssh access; we're using SSH keys to control access.
Aspace prod and staging, port 22 | Allows SSH access by developers to the ArchivesSpace server. | |
| Public web access |
80, 443
Aspace prod and staging, ports 80 and 443 | Allows public web access to the production and staging ArchivesSpace servers. |
| short term production firewall rules | Aspace prod, port 8983 | Used |
to allow developers and export code to access the ASpace API. | ||
| short term staging firewall rules | Aspace staging, port 8983 |
Used for short-term access to the SOLR configuration on ArchivesSpace production from developers' IP addresses.

Security Group
Description

Notes
CHF-Access-Web
CHF internal web access
80, 443
Allows a list of employees to connect to 80 and 443. This is not being applied to any machines; both staging and production ASpace already allow access to those two ports via Public-Access-Web.
Includes Offsite access addresses for Jonathan
internal-networking-production
Access between production machines
8080, 8983, 6379, 5432, 19999
All Samvera machines needed to be members of this group so they can communicate to share REST data.
Port 8080 is Fedora, 8983 is Solr, 6379 is Redis, 5432 is Postgres, 19999 is netdata for monitoring.
Do not mix production and staging boxes, this divide avoids security group rule tests from impacting production. The only box on both is monitor to watch both groups.
internal-networking-staging
Access between staging machines
8080, 8983, 6379, 5432, 19999
All Samvera machines needed to be members of this group so they can communicate to share REST data.
Port 8080 is Fedora, 8983 is Solr, 6379 is Redis, 5432 is Postgres, 19999 is netdata for monitoring.
See Temp-Production. |
In addition there is a default security group that appears unused, but cannot be deleted.
When a machine has multiple security groups, as long as any one of the groups allows access the connection will work through the firewall. Anything not covered will be rejected however.
