Password-controlled access requires clients to authenticate through a private login ID and password before entering the system. After authenticating to the system, sessions that remain inactive for a period of time are expired, requiring the client to re-authenticate before continuing. Passwords are protected in the system using sophisticated hashing schemes, never shared, and combine with a Secure Sockets Layer (SSL) protocol transport layer to protect against eavesdropping, server impersonation, and stream tampering. Passwords must be reset at least every 90 days and must be at least 8 characters in length and that contain at least one each letter and digit.
System access can be further restricted on the group or user level by IP address or IP range. Any attempt to authenticate to the system from a client machine outside of the configured IP address or IP range will be rejected.
All transactions are performed in a secure environment. The client’s web browser automatically secures the session with the InstaScreen server by connecting to it using the Secure Sockets Layer (SSL) protocol with 128-bit encryption. The data travels between client and server encrypted, and can only be decrypted with a public and private key pair.
Firewalls, Intrusions Detection and Filtering Routers
The application server is protected by firewalls, intrusion detection, and filtering routers which verify the source and destination of the request traveling in information packets. The routers and firewalls are configured to reject any unauthorized traffic. The system uses network devices that only allow permitted traffic through the devices. Routers keep out traffic that does not emanate from either end of the secured session between the client and the server.
The physical server machines are hosted at a state-of-the-art collocation facility that is staffed on-site 24/7 to provide an immediate response to any incident. Access to the facility is restricted to authorized personnel and is secured by both password-protected keypads and biometric scans. Door, glass, and motion events at the facility are digitally recorded and archived, as well as observed live by facility staff for any suspicious activity. UPS systems and a 500-kilowatt diesel generator ensure electrical service to the facility. Multiple fiber providers provide Internet connectivity with diversified entry points into the facility. The cooling system incorporates redundant components, excess capacity, and high-efficiency technologies to maintain an optimal operating environment for the servers.
Data servers are configured with mirrored hard drives to provide real-time, fail over redundancy. Additionally, nightly backups of data are scheduled, with archives removed weekly to an offsite location for additional redundancy.
Clients are expected to guard their password carefully and to not share it with or disclose it to anyone, for any reason. VICTIG staff will never ask a client for their password. Clients must also ensure the security of their InstaScreen sessions, completely logging out of the system when finished and not leaving active sessions unattended. Paper and electronic copies of reports must be carefully controlled to prevent the unauthorized distribution or disclosure of personally identifying applicant information. A robust and secure system requires a multi-faceted solution with hardware, software, and education. Critical to the success of any secure system is the education of its user community and employees on the importance and sensitivity of information. Knowledge of why and how data is secured, and the permissible uses of all information, is essential in maintaining the integrity of the system and its contents.
