Although some IM and P2P applications can generate real value for businesses, IT security experts recommend centralized monitoring and administration of user access. Undesired applications should be blocked while applications that are truly advantageous for business should be freely accessible.
For example, many companies use the file sharing protocol BitTorrent to exchange large files or software downloads. In such cases, administrators need a way to provide employees authorized access to BitTorrent while risky or undesired applications remain blocked.
The latest release of the Astaro Security Gateway allows IT managers to recognize, classify, and block Skype connections and other popular instant messaging and peer-to-peer programs, such as AOL Messenger, ICQ, Google Talk, Jabber, IRC, MSN Messenger, and Yahoo! Messenger. Version 7.2 provides granular access control down to the user level while also supporting quality of service bandwidth control.
With Astaro, Skype connections and other complex, difficult-to-identify protocols, such as QQ or Winny, can be recognized in the data stream.
In many companies, administrators are struggling with the unrestricted availability of messenger and P2P software programs, which employees can install and use for business or private purposes without their knowledge, impacting network security. Data can be slipped past the company's firewall, and virus-infected files can enter the network. Additional negative consequences include heavy increases in network traffic, disruption of other applications, violations of compliance regulations, and diminished business productivity.
Version 7.2 of Astaro Security Gateway enables administrators to block recognized Skype communications, if desired, or simply receive notice of connection attempts. For optimal allocation of the bandwidth necessary for business-critical applications, bandwidth limits can be specified for certain protocols such as BitTorrent.
On the company network, exceptions to the internal security policy can be defined to grant granular access to specific instant messaging services or peer-to-peer applications for individual IP addresses or end systems.
Astaro Security Gateway V7.2 is available as a virtual appliance or software ISO starting at a list price of $345, or pre-installed on Astaro's hardware appliances. More info can be found at www.astaro.com.
