Automated submission of threat information to McAfee Advanced Threat Defense and automated sharing of that information across the enterprise improves protection while saving security operations time and hassle. This large global software company with more than 20,000 employees in 20 countries has implemented an IT infrastructure that is highly virtual and fluid. Systems come and go daily on the company’s network. For instance, in a recent week, 45,000 systems, including virtual machines, connected to the corporate network. However, during peak periods, up to 150,000 endpoints can be connected. For the company’s senior manager of security engineering, who oversees the team responsible for deployment of all security tools across the global enterprise, this environment poses distinct challenges. Challenge: Close Gaps to Block Zero-Day Attacks Although the company employs the McAfee Complete Endpoint Threat Protection suite on all its high-risk physical and virtual endpoints, it also has many virtual endpoints connecting to its network that do not have a McAfee agent installed and are therefore not updated with the latest threat protection via the McAfee ePolicy Orchestrator (McAfee® ePO™) management console. The company’s more important virtual machines host a McAfee agent but many “low-risk” systems do not. Until recently, if one of these unmanaged endpoints downloaded a malicious file, the McAfee ePO softwaremanaged endpoints would be at risk because they had no way of knowing of the existence of that threat within the environment. “Zero-day threats are our biggest concern,” remarks the senior manager of security engineering. “If any of our endpoints—managed or unmanaged—downloads a zero-day threat, we want our whole environment to know about it, and we want to be able to react appropriately as fast as possible.” In addition, if a managed endpoint became infected, security analysts would receive an alert, but, because of the fluidity of systems coming on and off the network, by the time an analyst has logged in and has attempted to find the suspicious payload, the system could easily have moved offline, essentially removing the information needed to understand what had transpired. As a result, security operations center (SOC) engineers found that they had to spend extra time tracking down infected systems and remediating them. Hunting and Blocking Zero-Day Threats with McAfee Advanced Threat Defense Along with McAfee Complete Endpoint Threat Protection, the company had implemented the Data Exchange Layer (DXL) communication fabric and McAfee Threat Intelligence Exchange. DXL connects and optimizes security actions across multiple vendor products, as well as internally developed and open source solutions, and McAfee Threat Intelligence Exchange leverages DXL to bi-directionally share threat information across all DXL-connected systems. To this automated threat reputation-sharing framework, the company added McAfee Advanced Threat Defense for “zero-day hunting,” as the senior manager of security engineering describes the appliance’s main role.  “If an unknown or suspicious file comes across one ofour endpoints protected by McAfee Endpoint Security, the file is automatically sent to McAfee Advanced ThreatDefense for sophisticated static and dynamic behavioralanalysis,” explains the senior manager of securityengineering. “If McAfee Advanced Threat Defensedeems the file to be malicious, its reputation is thenautomatically broadcast via McAfee Threat IntelligenceExchange to all the endpoints connected to DXL. Thisautomatic distribution of threat reputation informationhelps us block zero-day threats before they can harmour environment.” Enhancing Intrusion Detection with Bro But what about threats entering the environment through the company’s many unmanaged endpoints? To extend detection to these systems, the company turned to the open-source Bro network security monitoring platform. Bro ingests the company’s network traffic off a span or inline tap and converts the traffic data into logs and metadata in binary format. In a typical week, Bro submits approximately 6,000 files to McAfee Advanced Threat Defense for analysis. Of those, approximately 10% to 20% end up in the McAfee Threat Intelligence Exchange threat reputation database and are subsequently shared throughout the enterprise. “Bro gives us the ability to retain network traffic in a searchable format, which is extremely useful,” the senior manager of security engineering explains. “For instance, using Bro, we can search for source or distributed IP so we can easily conduct lightweight investigations— discover who or what connected to a specific IP address, what the payload looks like, determine the packet size, and so on.” The information captured by Bro supplements the threat information delivered via the McAfee Global Threat Intelligence cloud and disseminated via McAfee Threat Intelligence Exchange. With the Bro script and advice provided by McAfee (now available as a deployment kit), the senior manager of security engineering’s team integrated Bro with McAfee Advanced Threat Defense so that the Bro traffic data is automatically submitted to McAfee Advanced Threat Defense, just as suspicious files from McAfee Endpoint Security are automatically submitted through McAfee Threat Intelligence Exchange. Since the team was already very familiar with Bro, the integration was straightforward. Automatic Immunization Against Threats that Hit Unmanaged Endpoints “If one of our unmanaged endpoints downloads a malicious file, Bro will capture that event among the network traffic and submit it to McAfee AdvancedThreat Defense for analysis,” notes the senior managerof security engineering. “If McAfee Advanced ThreatDefense determines the file is malicious, then thatmalicious reputation will be shared automatically withevery McAfee ePO software-managed system in ourentire enterprise—in other words, with all the systemswe care about. Put another way, if one of our unmanagedvirtual machines downloads a malicious file, all of ourmanaged devices automatically receive an immune shot.” Facilitating and Accelerating Incident Response With the McAfee Advanced Threat Defense/Bro integration and threat reputation information automatically disseminated across endpoints via McAfee Threat Intelligence Exchange, inoculation of endpoints happens much faster than it did before. Consequently, there is a much greater likelihood that a system will “receive the immune shot” before it goes offline. In addition, because the actual event and surrounding intelligence is captured by Bro, even if the system goes offline, McAfee Advanced Threat Defense, as well as security analysts, have a great deal more information to help determine appropriate action, and, if necessary, to remediate more quickly. “With the McAfee automated threat framework and supporting intelligence from the Bro integration, plus automated remediation that we have also set up, our SOC very rarely needs to pay attention to endpoint incidents,” points out the senior manager of security engineering. “The Bro integration and all that automation save a ton of time.” To fortify its defenses further, the company continues to build upon its DXL-based integrated security framework. For instance, the company is currently in the process of adding McAfee DLP Monitor to gather, track, and report on data in motion across its entire network and augment its McAfee DLP Endpoint host-based data protection. “The more we can integrate our systems and automate responses, the safer we will be,” says the senior managerof security engineering.

Harry Folloder loves his job as Chief Information Officer of Waypoint, the premier sales and marketing agency for foodservice (as well as non-foods channels) in North America. As CIO, he oversees the use of technology within the company and across its 1,500 endpoints and three data centers. “It’s fun,” he says. “I get to spend a lot of my time innovating and looking for ways to use technology to increase the value we provide our customers.” No News is Good News Folloder’s job was a lot less fun and his phone a lot less quiet a few years ago. “So much of my security staff’s time was spent dealing with false positives and other program problems; they would end up calling me and griping about the problems,” recalls Folloder, who is also CIO of Marlin Networks, the leading marketing agency in the food service industry. “Sometimes the security issues would even take salespeople out of the field for a day or two while waiting for the issue to be resolved. Ultimately, I decided we needed a security partner focused solely on security, with products that do what they’re supposed to do, so I don’t have to hear about them and, more importantly, so our end users can keep focusing on doing their part to serve our customers and grow our business.” Folloder says his top priority as CIO is to be an ambassador to clients and customers and to keep the business moving forward. “Keeping security running is not my job,” he says. “When security is running smoothly and my phone is quiet, with no unwanted calls from my security team or my Board, then I can focus on my real job.” Result of Migrating to McAfee Endpoint Security: Better User Experience and Reduced TCO Folloder found in McAfee the security partner he was looking for. After replacing Waypoint’s previous endpoint protection software with McAfee Complete Endpoint Protection Enterprise (now called McAfee Complete Endpoint Threat Protection), phone calls from his staff decreased significantly. When Folloder and his staff heard that McAfee was introducing a new, more intelligent, more collaborative endpoint protection framework, McAfee Endpoint Security, they couldn’t wait to take advantage of it. After running McAfee Endpoint Security version 10.2 briefly in a test environment, they used the McAfee ePolicy Orchestrator® (McAfee ePO™) central console to push it out across all of Waypoint’s approximately 1,500 nodes. The migration of the virus scanning engine, McAfee VirusScan® Enterprise, and McAfee SiteAdvisor® software from the McAfee Complete Endpoint Threat Protection to McAfee Endpoint Security took place within a two-and-a-half-week period that also included deployment of McAfee Threat Intelligence Exchange across all endpoints and McAfee Advanced Threat Defense for sandbox analysis. “Migrating to McAfee Endpoint Security was one of the easiest platform migrations ever,” notes Folloder. “It went off without a hitch. The only calls received were from a handful of users who had shut down or rebooted in the middle of the upgrade process. Folloder and his staff have been extremely pleased with the results. “McAfee Endpoint Security is a much better experience for our administrative staff, providing better protection with less management time,” says Folloder. “It allows us to better serve our business with higher quality levels, lower total cost of ownership, and lower cost of administration. It also allows our business users to focus on their jobs rather than issues caused by security software.” No Ransomware. Period. Folloder was most excited to integrate McAfee Endpoint Security with McAfee Advanced Threat Defense via McAfee Threat Intelligence Exchange, for even greater ability to combat advanced threats and deliver actionable threat forensics. Leveraging the McAfee Data Exchange Layer (DXL), McAfee Threat Intelligence Exchange combines multiple internal and external threat information sources and instantly shares this data along the DXL backbone that extends to all of the company’s nearly 1,500 nodes. Integration of McAfee Endpoint Security with Threat Intelligence Exchange enables information generated by McAfee Advanced Threat Defense to be shared immediately with all endpoints. “McAfee Threat Intelligence Exchange is information sharing at its best; you’re aggregating everything that McAfee and all of its customers are seeing in a way that helps crowdsource the good info,” explains Folloder. “It gives us comprehensive, near real-time threat intelligence and shares it with all our machines to make them safer.” As for McAfee Advanced Threat Defense, Folloder says: “One of the initial things that caught my eye was the inspection methodology and in-depth analysis that Advanced Threat Defense does, that I just didn’t see elsewhere. Its simple packet inspection, which is what a lot of malware targets, and in-depth analysis of disassembled raw code drew me in immediately. Then when I found out what else it did, I became a true believer. Best of all, it fulfills its promise to detect zeroday, zero-hour attacks, and does so in a very elegant way with minimal end-user impact.” “Since implementing McAfee Endpoint Security, Threat Intelligence Exchange, and Advanced Threat Defense, we haven’t had a single case of ransomware,” says Folloder. “Period.” McAfee Advanced Threat Defense also catches many undesirable files that try to install on users’ browsers, such as adware, the Mindspark toolbar, fake utilities like Optimizer Pro and PC Accelerator, and plugins for music players, coupons, and online games. Experience Improved for Both Business Users and Security Administrators Waypoint’s legacy endpoint protection—McAfee VirusScan Enterprise software—although many times better than the company’s previous antivirus solution, still required some heavy processor usage at times. With the upgrade to McAfee Endpoint Security, however, the impact of malware scanning on CPU utilization has diminished significantly.  “Our end users have a much better experience,” says Folloder. “Whether or not their personal computer has experienced a significant change in processor usage, all of our users perceive less interference and faster computing. Since the rollout of McAfee Endpoint Security, we haven’t heard a single complaint about corporate virus scans.” The user experience for Waypoint’s two information security administrators has also improved with the migration to McAfee Endpoint Security. “I don’t have to interact with [Endpoint Security] much, which is a good  thing,” says Folloder, “but my techs say that it has a much nicer, more modern interface than before.” Quiet and Peace of Mind “Worth Every Penny” “At my level, the measure of success for a product is that I haven’t had to hear about it or worry about it,” says Folloder. “I haven’t had to mess with McAfee Endpoint Security. I haven’t had to hear from anyone in the C-suite or their direct reports. It is doing exactly what we paid for it to do and I love it.” Furthermore, adds Folloder, since the migration to McAfee Endpoint Security, endpoint protection has not interrupted a single associate or sales person’s work. “The less interruptions of business and service to our customers, the better,” he states. “That’s really my overarching goal. That’s why I invest in products like McAfee Endpoint Security. It’s worth every penny.” A True Security Partner But it’s not just the quality of products that count. “I look for partners, not vendors,’ says Folloder. “At the end of the day we’re a service company. Partnering with the best allows us to focus on our core competency.” “I know I sound like an ad for McAfee, but I really do love that I can sleep at night, knowing that Waypoint’s IT infrastructure is protected by a company that is focused on protecting my environment and not distracted by backup or storage or whatnot,” continues Folloder. “Ask yourself, ‘Is my security vendor focused specifically on securing my environment? Does it have leading researchers and state-of-the-art resources to protect my infrastructure and users, and to keep innovating and evolving to face new threats?’ Take a hard look. My experience with McAfee has been everything a partnership should be and more.”

HollyFrontier is a Fortune 500 independent refiner and distributor of petroleum products. The company operates six refineries—five in the middle of the US and one in Ontario, Canada. The company employs 3,500 people across 43 sites in the US, 16 in Canada, and a handful of locations in China and the United Kingdom.
Search for Better Endpoint Protection Leads to Revamped Security Architecture As part of an endpoint security review, HollyFrontier invited six leading vendors to make presentations in competition for the business. McAfee stood out from the other vendors with its integrated security strategy and attainable vision of a threat defense lifecycle that learns and adapts to meet changing requirements. “We agreed wholeheartedly with the McAfee® approach,” says Cybersecurity Engineer Phillip Fort, the main person responsible for HollyFrontier’s day-to-day security posture. “With the integrated McAfee ecosystem, our limited security team can automate a lot of security tasks. We can essentially do a lot more to protect our company a lot faster, without adding staff.” In addition to McAfee endpoint protection and its bundled McAfee ePolicy Orchestrator (McAfee ePO) central console, in just a few weeks, HollyFrontier deployed:
■    McAfee Network Security Platform intrusion prevention system (IPS) appliances.
■    McAfee Data Exchange Layer, the open-source fabric that connects security components to automate integration and real-time data exchange.
■    McAfee Threat Intelligence Exchange, which aggregates threat intelligence from local and global sources and shares file reputation information across McAfee Data Exchange Layer-connected systems.
■    McAfee Enterprise Security Manager and other components of the McAfee SIEM solution set.
■    McAfee Advanced Threat Defense sandboxing appliance. Within a year, the company also began deploying McAfee Endpoint Threat Defense and Response and McAfee Web Gateway. Infection Rate and Ransomware Reduced Dramatically HollyFrontier initially deployed the McAfee Complete Endpoint Threat Protection suite. However, because of “all the ransomware going around,” HollyFrontier was anxious to install McAfee Endpoint Security and its Dynamic Application Containment (DAC) functionality. When DAC encounters a file that does not have a trusted reputation or is unknown, it immediately quarantines the file before it can infect “patient zero.” Consequently, as soon as McAfee Endpoint Security became available, the company migrated the McAfee VirusScan® Enterprise portion of its endpoint protection suite to the McAfee Endpoint Security Threat Prevention module, first rolling out version 10.1, then upgrading to version 10.2, and upgrading again to version 10.5.
Although DAC initially blocked a few legacy applications that are still used, Fort was able to quickly create exclusions for those applications. “The McAfee Endpoint Security graphical user interface is very easy to use,” he notes.“Once I created the first couple exclusions, the rest were easy.” It didn’t take long for the biggest impact of the new endpoint protection framework to became evident. “After implementing McAfee Endpoint Security and DAC, our malware infection rate plummeted,” states Fort. “We used to have ransomware attacks each month, but we have had none since migrating to McAfee Endpoint Security and integrating it with McAfee Threat Intelligence Exchange and McAfee Advanced Threat Defense … Truthfully, I don’t have to deal with McAfee Endpoint Security very much—and that’s a good thing.” Results of Sandbox Analysis Automatically Shared Throughout Enterprise
As Fort contemplated the benefits of an integrated security platform prior to its implementation, the integration he was most excited about was that of the endpoint and other security components with the McAfee Advanced Threat Defense.
“McAfee Advanced Threat Defense does as much or more than other sandboxes, but its integration with other McAfee solutions is what makes it so incredibly powerful,” says Fort. “It immediately detects and contains a potentially malicious file on the endpoint, IPS, or gateway.
First it sends the file automatically to McAfee Advanced Threat Defense for analysis, and, if found malicious, the file is then automatically removed across the entire enterprise. That is truly transformative for our small security team,” states Fort. “It augments our own abilities and saves us a lot of time.” Every day a security analyst checks McAfee Advanced Threat Defense to review the list of files that the appliance has convicted as malicious. “Once an administrative assistant clicked on a phishing email,” explains Fort. “The IPS, McAfee Network Security Platform, blocked the suspicious file and sent it to McAfee Advanced Threat Defense, which determined that it was bad. The file appeared in the day’s list of convicted files, and we confirmed that it was indeed blocked and automatically entered in the McAfee Threat Intelligence Exchange reputation database shared throughout the enterprise.”
Periodically, the HollyFrontier security team runs assessments in which sample malware is put on a machine. “We then watch to make sure the malware shows up in McAfee Advanced Threat Defense and is removed from the host machine and blacklisted throughout the enterprise,” clarifies Fort. “It works every time—just as it’s supposed to.” Increasing Visibility and Facilitating Reporting with McAfee SIEM The desire for better visibility across the enterprise drove HollyFrontier to replace its aging SIEM with the McAfee SIEM technology. According to Fort, McAfee SIEM technology provides a much more complete security picture and widespread visibility across the network, which helps in countless ways. To cite just one example, a considerable number of users were becoming locked out as they tried to reset their passwords because they had failed to log off other machines. A security analyst simply entered the user ID in the McAfee SIEM system, and immediately could see exactly which machines a user was logged into, whether or not he was locked out, and whether he should have access—and then could reset passwords as necessary. “In that case and many more, McAfee Enterprise Security Manager technology saves us a lot of investigative time,” says Fort. The HollyFrontier security team also uses many out-of- the-box rules and alerts, as well as custom ones within the McAfee SIEM solution. “Even if we haven’t developed a custom rule, if I have just a little information on a security event, it is easy to drill down and do a search based on single or multiple variables to find as much additional information as I need,” explains Fort. The McAfee Enterprise Security Manager solution also makes reporting easier. For example, to produce a quarterly security review to upper management, Fort simply runs out-of-the-box executive reports created by the McAfee SIEM solution and McAfee Advanced Threat Defense from within McAfee ePO software.
Rapid Searching Saves Time, Eliminates Vulnerabilities Faster
According to Fort, before learning about the McAfee integrated security platform, he had “fallen in love” with an endpoint detection and response (EDR) product from another vendor. “When we looked at McAfee Endpoint Threat Defense and Response, however, we realized it did everything that other solution did,” he recalls. “It gives us all the information we ever wanted to know— really, really fast.” With the McAfee EDR software, the HollyFrontier security team can eradicate vulnerabilities much faster. If Fort learns of a vulnerability in a specific version of an application—for instance, in Microsoft Office 2013—he can use the McAfee Active Response search functionality to quickly and easily find out exactly how many desktops have that version or create a list of all endpoints with that version. It took less than a minute for one of Fort’s colleagues to find all versions of Adobe Acrobat in the enterprise recently and just a few more minutes to determine which endpoints required updating. After pushing out the update, he clicked to rerun the search to confirm that all the updates were successful.
“The rapid searching we can do using McAfee Active Response saves us a tremendous amount of time,” says Fort. “We used to manually maintain inventory spreadsheets of all the various applications and systems. Now we can run real-time reports in seconds, and everyone is confident they are correct.” Adding Hybrid Web Protection At a McAfee user conference, while Fort was singing the praises of McAfee Network Security Platform and McAfee Advanced Threat Defense to other attendees.
Many of the participants were raving about McAfee Web Gateway, claiming it was their favorite McAfee product, prompting Fort to investigate. He quickly became convinced that McAfee Web Gateway was worth the investment, even though the company had an adequate web gateway solution. In addition to being able to share threat information in near real time with the other McAfee Data Exchange Layer-connected security solutions, McAfee Web Gateway offers more granular control and the ability to deploy a hybrid environment managed from the same console.
As a result, HollyFrontier is in the process of deploying its first McAfee Web Gateway appliance and McAfee Web Gateway Cloud Service. HollyFrontier employees working from home or on the road will be protected by the same corporate web security policies as users at corporate locations. In addition, any malware detected by McAfee Web Gateway is sent immediately to McAfee Advanced Threat Defense, and its information is shared throughout the enterprise. Integration and Increased Protection Ease Security Administration “With the McAfee integrated security infrastructure and McAfee ePO software, I can manage just about everything through one pane of glass,” says Fort. “That alone makes administration so much easier, but so does increased protection. If there is an infection somewhere else in the world, thanks to McAfee Threat Intelligence Exchange, my network knows about it and is protected before the infection even reaches us. If, on the other hand, the malware is detected within our environment, it is immediately sent to McAfee Advanced Threat Defense for analysis, and the rest of the environment is automatically informed. We have reduced operational overhead dramatically while improving our security posture.”
Fort has not only been impressed with McAfee products and their integration with one another, but also with McAfee personnel. “Any time I need anything, I just call or email my McAfee Security Engineer, and he responds right away,” he notes. “McAfee Platinum Support is also extremely responsive. I can usually get the help I need within a couple of minutes. We learned early on that McAfee is a strategic security partner as well as a dependable one.”
