V-94713
|
High |
Symantec ProxySG must terminate all network connections associated with a device management session at the end of the session, or the session must be terminated after 10 minutes of inactivity except to fulfill documented and validated mission requirements. |
Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended. In addition, quickly terminating an idle session will also free up resources committed by... |

V-94709
|
High |
The Symantec ProxySG Web Management Console and SSH sessions must implement cryptographic mechanisms to protect the confidentiality of nonlocal maintenance and diagnostic communications. |
This requirement requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP. If unsecured protocols (lacking cryptographic mechanisms) are used for sessions, the contents of those sessions will be susceptible to eavesdropping, potentially putting... |
|
V-94707
|
High |
Symantec ProxySG must be configured to use only FIPS 140-2 approved algorithms for authentication to a cryptographic module with any application or protocol. |
Unapproved mechanisms that are used for authentication to the cryptographic module are not validated and therefore cannot be relied upon to provide confidentiality or integrity, and DoD data may be compromised.
The Symantec ProxySG can be configured in FIPS-mode, but this is not recommended by the vendor or DoD. Instead,... |
|
V-94703
|
High |
Symantec ProxySG must transmit only encrypted representations of passwords. |
Passwords need to be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily compromised.
Network devices can accomplish this by making direct function calls to encryption modules or by leveraging operating... |
|
V-94695
|
High |
Symantec ProxySG must use only approved management services protocols. |
In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable unused or unnecessary physical and logical ports/protocols on information systems.
Network devices are capable of providing a wide variety of functions and services. Some... |
|
V-94657
|
High |
Symantec ProxySG must configure Web Management Console access restrictions to authorized IP address/ranges. |
It is important that administrative access (SSH, web) to an appliance using the account of last resort be able to be restricted to only the appropriate networks/subnets in order to reduce the likelihood of unauthorized access. |
|
V-94655
|
High |
Symantec ProxySG must be configured to enforce user authorization to implement least privilege. |
To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems must be properly configured to incorporate access control methods that do not rely solely on the possession of a certificate for access. Successful authentication must not automatically... |
|
V-94413
|
High |
Symantec ProxySG must enable Attack Detection. |
DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity.
Symantec ProxySG Attack Detection prevents or limits the effects of denial of service (DoS) and distributed-DoS (DDoS) attacks by limiting the... |
|
V-94705
|
Medium |
Symantec ProxySG must not have a default manufacturer passwords when deployed. |
Network devices not protected with strong password schemes provide the opportunity for anyone to crack the password and gain access to the device, which can result in loss of availability, confidentiality, or integrity of network traffic.
Many default vendor passwords are well known or are easily guessed; therefore, not removing... |
|
V-94701
|
Medium |
Symantec ProxySG must be configured to enforce a minimum 15-character password length for local accounts. |
Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to determine strength and how long it takes to crack a password.
The shorter the password, the lower the number... |
|
V-94699
|
Medium |
Symantec ProxySG must configure SNMPv3 so that cryptographically-based bidirectional authentication is used. |
Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Bidirectional authentication provides stronger safeguards to validate the identity of other devices for connections that are of greater risk.
A local connection is any connection with a device communicating without the use of a network. A... |
|
V-94697
|
Medium |
Symantec ProxySG must implement HTTPS-console to provide replay-resistant authentication mechanisms for network access to privileged accounts. |
A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be vulnerable to a replay attack.
An authentication process resists replay attacks if it is impractical to achieve a successful authentication by... |
|
V-94693
|
Medium |
Symantec ProxySG must configure the maintenance and health monitoring to send an alarm when a critical condition occurs for a component. |
Predictable failure prevention requires organizational planning to address device failure issues. If components key to maintaining the device's security fail to function, the device could continue operating in an insecure state. If appropriate actions are not taken when a network device failure occurs, a denial of service condition may occur... |
|
V-94691
|
Medium |
Symantec ProxySG must obtain its public key certificates from an appropriate certificate policy through an approved service provider. |
For user certificates, each organization obtains certificates from an approved, shared service provider, as required by OMB policy. For federal agencies operating a legacy public key infrastructure cross-certified with the Federal Bridge Certification Authority at medium assurance or higher, this Certification Authority will suffice. |
|
V-94689

V-94673
|
Medium |
Symantec ProxySG must be configured to synchronize internal information system clocks with the primary and secondary time sources located in different geographic regions using redundant authoritative time sources. |
The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run mode) and increasingly inaccurate time stamps on audit events and other functions.
Multiple time sources provide redundancy by including a secondary source. Time synchronization is usually a hierarchy; clients synchronize time... |
|
V-94671
|
Medium |
Symantec ProxySG must compare internal information system clocks at least every 24 hours with an authoritative time server. |
Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when conducting forensic analysis and investigating system events. Sources outside of the configured acceptable allowance (drift) may be inaccurate. Additionally,... |
|
V-94667
|
Medium |
Symantec ProxySG must be configured to support centralized management and configuration of the audit log. |
Without the ability to centrally manage the content captured in the audit records, identification, troubleshooting, and correlation of suspicious behavior would be difficult and could lead to a delayed or incomplete analysis of an ongoing attack.
The DoD requires centralized management of all network component audit record content. Network components... |
|
V-94665
|
Medium |
Symantec ProxySG must enable event access logging. |
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.
