Environment Considerations
Network ports
Quasar V3 and V4 agents use 3 TCP ports for their connection to the server.
- TCP 55555 (“five fives”),
- TCP 55557 (“four-fives-seven”),
- TCP 55559 (“four-fives-nine”)
Connections are established from the agents to the server.
Note: Quasar 4 network protocols are fully backward-compatible with Quasar 3.
V3 and V4 agents and servers can be mixed without issue.
Anti-Virus
Quasar and its scanning process should be exempt from antivirus scrutiny for a number of reasons:
- This process starts with the exporting of mailboxes from Exchange servers to PSTs.
- It is local-only to the Quasar server. Apart from initial copying-on of the PSTs, the scan process operates only on the box and its local drive.
- Antivirus realtime scanning will trigger on the PST contents as they are scanned by Quasar, significantly slowing the Quasar scan itself.
- Antivirus detecting and deleting/quarantining files from the PST will interfere with Quasar scanning them, which could lead to missed results. We don’t want to deliver a ‘clean’ report when it isn’t actually clean thanks to antivirus hiding the file from Quasar scanner.
- These PSTs are merely snapshots of the real production data and will be deleted once the scan process is completed for them.
- The real production mailboxes should continue to have suitable antivirus operating on them and as such the actual production security threats would be dealt with effectively there.
Exclusions:
- The Quasar Agent
- Quasar Activities
- Quasar Data Folders
- Quasar Files
- Quasar Application Folders
Summary:
Antivirus and application whitelisting software can interfere with Quasar.
This could result in slow scans or excessive CPU use due to the way that the protection software interferes with the application and associated processes.
All of the Quasar processes and associate files need to be whitelisted on your antivirus or application whitelisting solution.
If the Quasar solution has not been appropriately whitelisted this can prevent the application from functioning as intended.
Service Accounts
WARNING: Quasar will only run under the account it is installed as (e.g. local admin account or service account with local admin privileges).
