The Web Security Service provides several options that allow you to specify how the Unified Agent behaves on the client and how to route traffic.
Determine the Fail Behavior, which is what happens to web requests if the Web Security Service is not available from remote locations. You have the option to Prompt users when a new Unified Agent version is available or prevent automatic updates and distribute from a central location at a time of your choosing.
The option to allow employees access the Proxy Settings tab on their Unified Agent applications is a decision performed before installation.
By default, a Unified Agent process sends the User ID through the tunnel to the Web Security Service.
For a current list of known third-party applications that cause this issue, see NT AUTHORITY\SYSTEM Username Returned From the UA.
If clients are configured to have ports other than the defaults (80, 443, and 8080) listen for web requests, add those ports to the Web Security Service. If a destination request contains one of these IP addresses, the traffic bypasses the Web Security Service the client connects directly. Client Connector only: the Web Security Service can only bypass the first 256 items in the list. Allow remote client requests to bypass specific domains (only available for Unified Agent v4.4+).
To enforce accurate user credentials rather than rely on locally cached credentials, select Enable Captive Portal for remote users (using Unified Agent). For more details about the network footprint, see About Challenge-based Auth (Captive Portal).
Malware is constantly evolving, so you need a dynamic security defense that can keep up with the latest Web-based threats. WebPulse supports more than 50 languages and utilizes a combination of traffic, content and reputation analysis of real-time requests to build a comprehensive view of the web-based malware ecosystem. To keep pace with the evolving threat landscape, Blue Coat Security Labs continually adds new defenses to WebPulse that are immediately available to all 75 million users without updates or downloads. Dynamically analyzes URL requests and immediately shares threat intelligence throughout the cloud community.
Leverages 16 advanced threat analysis tools to provide immediate and continuous protection against known and unknown Web-based threats.
Delivers the latest security advances without requiring software downloads or other update cycles. One of this year's new categories, threat intelligence products, can generally be thought of in two ways: as an intelligence feed that is consumed by various other products, or as a product that utilizes intelligence to block malware and sophisticated attacks. The prevailing trend in the space is to have security controls that can consume threat information to block malicious activity --a characteristic of all three of the finalists --though these products will need to evolve in the near future, according to Rick Holland, principal analyst at Cambridge, Mass.-based Forrester Research Inc. Three products came out on top in a crowded category, teeming with a wide range of platforms and services. FireEye's Threat Intelligence services and products impressed readers this year both with how quickly they can react to new threats, and the service and support offered by the vendor. The company offers three subscription levels for its Threat Intelligence service: Dynamic Threat Intelligence, Advanced Threat Intelligence and Advanced Threat Intelligence Plus. FireEye Threat Intelligence delivers auto-generated indicators of compromise based on information taken from customer deployments, promising to reduce the time until an attack is detected and blocked.
To take full advantage of FireEye's Threat Intelligence services, organizations will also need to deploy some of the other products in the vendor's Threat Prevention Platform.
Readers scored Blue Coat Systems' WebPulse offering highly in a number of areas, including its ability to react quickly to new threats, the service and support offered by the vendor and rated it a good value overall based on the investment.
IT security teams can automatically block suspicious URLs and their associated malware with Blue Coat's WebPulse.


That information is then relayed to the WebPulse cloud so that other users can benefit from the analysis.
Cisco's Advanced Malware Protection (AMP) offering, the result of the vendor's blockbuster $2.7 billion acquisition of security firm Sourcefire in 2013, received some of the highest ratings from readers in this category for its ability to respond quickly to new threats. AMP's threat intelligence hinges in part on its integration with ThreatGrid, a malware analysis service, available on-premises or in the cloud, that uses sandboxing and a proprietary threat database to detect potential exploits. The AMP technology can be deployed in a number of ways, from being integrated into dedicated ASA firewalls and other network security appliances to working on endpoints and mobile devices. Cisco's AMP mostly serves to analyze, detect and block malware throughout the attack lifecycle. The threat intelligence gathered from AMP's analysis activity is fed into Cisco's Talso threat research group, with the promise that information on fending off threats will be shared with the Cisco community and fed into the company's products to block future attacks.
Learn how threat intelligence can give your enterprise security team the upper hand over attackers. Cloud identity management can offer a lot of security benefits, but enterprises need to answer some questions before deployment. The degree of network control IT pros possess is expanding with new features in network monitoring systems.

Marketing materials paint a rosy picture, but a managed WAN implementation can be a challenge for enterprise network engineers. When companies get serious about understanding what it costs to get work done, employment will change dramatically.
Surface Pro 2 and Surface Pro 3 are different enough that Microsoft is keeping both on the market as competing products. Windows 10 collects a lot of user data but Microsoft says it is all in an effort to deliver the best user experience.
Define policy on the Microsoft ISA server to forward web requests plus user identification information to the Blue Coat Web Security Service.
To assist with deployment planning, download and complete the Proxy Forwarding Planning Form. Step 2a€”Create another access rule for DNS for all users to both internal and external sources. Step 3a€”Create an access rule to allow for Auth Connector TCP connections on port 443 (SSL) .
If your region requires a second Web Security Service IP address, repeat Step 4 and add it.
Scroll down to the Microsoft services and verify that the Status column for Microsoft Firewall displays Started.
To forward credentials from the Active Directory to the Web Security Service, you must add those groups to the bc-isapifilter.ini file.
Paste or define groups of interest in a separate file, validate them, and paste them into this file.
Configure the gateway firewall device to allow traffic from the gateway ProxySG on ports 8080 and 8443.
This ensures an accurate account of who initiated the request and allows for policy enforcement and reporting. To be compatible with third-party interceptions that cause this issue, instruct the Unified Agent to send the logged-in username (applies to Unified Agent v4.6+).
This option requires deployment of the Auth Connector application, which integrates with your Active Directory to provide username and group information.
With custom script analyzers, anti-malware and anti-virus scanning, and sandboxing and browser simulations as well as other proprietary security defenses, WebPulse identifies and blocks 3.3 million threats per day.


We congratulate the winners chosen by Information Security readers as the best of Threat Intelligence 2014. Of course, FireEye's ability to profile and react to threats was buoyed by its $1 billion acquisition in 2013 of Mandiant, a high-profile incident response and forensics firm. Dynamic is the most basic level and allows customers with FireEye's own technologies to share threat intelligence with the FireEye cloud, with the promise of being able to block attacks based on the returned data. That includes a number of cloud-based products and physical appliances that defend various areas of an enterprise environment, including network, email, endpoint and mobile.
If a URL has already been visited recently by a different Blue Coat user and the details were uploaded to the cloud, WebPulse will automatically assign the site a rating that can then be used by administrators to block or allow it within their organization. Users of Blue Coats' ProxyAV inline Web traffic scanning appliances also feed data to the WebPulse cloud to similar effect. Readers also felt the Cisco product provided good overall awareness of a situation based on security context. Cisco is expected to tighten its integration with ThreatGrid after acquiring the longtime partner of Sourcefire in May. Products throughout the Cisco ecosystem such as Cisco Cloud Web Security and Cisco Web and Email Security appliances can also utilize AMP as an integrated feature. File reputations can be analyzed inline, files with unknown behavior can be analyzed in a sandbox environment and, perhaps the most unique selling point for AMP, files will continually be analyzed to determine if a threat has emerged from a previously innocent file. Intriguingly, in a move that Holland pointed to as a potential indicator of the future, Cisco also recently signed a deal that made data from AMP's sandboxing available to customers of Symantec's managed security services. If you reside outside of the United States, you consent to having your personal data transferred to and processed in the United States. An authentication filter that can perform the authentication to the users workstation must be configured. FireEye continues to be out in front, announcing plans in September to offer native threat intelligence in the cloud with an analytics product for Amazon Web Services. Advanced adds more context to the threat intelligence being returned, including details on known threat actors and malware as well as other indicators of compromise. All of the Threat Prevention technologies rely on FireEye's proprietary multi-vector virtual execution (MVX) engine to detect advanced malware through real-time analysis techniques.
Those products then make use of that threat intelligence to block attacks before they strike. If a URL hasn't been visited previously --a possibility with the millions of URLs created every month --then WebPulse will utilize its cloud-based ratings engine to analyze the requested URL's language content, registration information, history, and more, to determine whether the site can be trusted.
With that latter capability, Cisco promises AMP customers that it can detect unknown threats when they are discovered and block similar attacks before they happen based on the collected information.
If a group is not added, the Web Security Service still generates the Web traffic from those clients; however, the user names are not available for policy. The most complete level, Advanced Threat Intelligence Plus, provides comprehensive reports on hacker groups and targeted industries using news, trends and analysis, and allows enterprises to share information directly with trusted partners. FireEye delivers auto-generated indicators of compromise based on information taken from customer deployments, promising to reduce the time until an attack is detected and blocked. WebPulse's analysis relies on a number of techniques, including antimalware and AV scanning, sandboxing and the use of proprietary content scanners, to determine whether a site hosts malicious content.
