Revision history Copyright © 2021 Symantec Corp. 4 Tech Note — Using the Audit App Introduction The CloudSOC Audit application is a powerful tool that helps you make intelligent decisions about which cloud applications you should embrace, and which you should avoid. Audit finds and monitors all the cloud applications being used in your organization, and highlights any risks and compliance issues these applications may pose. With Audit, you can quickly identify risky services that your employees have adopted, as well as identify the employees using these services. It shows you why each app is risky, as measured against over 60 objective security, compliance and business continuity criteria. Opening Audit To open the Audit app: 1. Log into your CloudSOC account with your administrator credentials. 2. In CloudSOC, click Audit as shown in the following. Audit is at or near the middle of the bar. Tip: Once you’re familiar with Audit, you can use the Audit submenu to go directly to specific Audit pages. Copyright © 2021 Symantec Corp. 5 Tech Note — Using the Audit App Audit opens to the Summary tab as shown in the following. The summary tab shows you an overview of your organization’s SaaS usage and risk exposure. Choosing data sources The Audit app uses data from log files generated by your network devices and proxies to show you your company’s actual SaaS activity. You can select to use one, several, or all available, data sources. The compressed source files sent to Audit must be less than 9 GB. Note: This Tech Note assumes that you have already uploaded firewall and proxy logs to CloudSOC. It also assumes that CloudSOC has already processed the logs, and that the results of analysis are available. For more information, see the Tech Note Managing Data Sources for the CloudSOC Audit App. Copyright © 2021 Symantec Corp. 6 Tech Note — Using the Audit App To select data sources for Audit: 1. At the top of any Audit page, click Select Sources as shown in the following. Audit opens a list of available data sources as shown in the following. 2. Select one or more of the available sources, or select All to use an aggregate of all available sources. If you are using a supported centralized proxy/firewall management solution to aggregate logs from multiple devices into one data source, you can further narrow your data source selection to a specific devices within the data source: 1. If it is not already selected, click the aggregated data source. Copyright © 2021 Symantec Corp. 7 Tech Note — Using the Audit App 2. Click the gear icon to open a panel that shows the devices aggregated into the data source. If the gear icon is absent, filtering by individual devices is not supported for the data source. 3. On the panel, select devices to include in the Audit view. Viewing and filtering audit results The power of the Audit app comes from in-depth research on Cloud applications such as SaaS, PaaS and IaaS conducted by the CloudSOC research team, and a powerful yet simple set of analytics tools. These features let you quickly drill down and answer key questions such as: ● What unapproved cloud applications are my users using most? ● Which enterprise cloud applications are the riskiest, and who is using those applications? ● What cloud services have been compromised in the last 90 days? ● Which SaaS applications have my users adopted recently that can be risky? ● Which cloud applications consume the most bandwidth? ● Which cloud applications are hosted in locations that violate company or regulatory requirements? Copyright © 2021 Symantec Corp. 8 Tech Note — Using the Audit App ● Which cloud applications fail to meet security and compliance requirements? ● What alternatives are there to the SaaS applications in use? Are there alternatives that fulfill my users’ needs but are more secure and enterprise-friendly? You can answer all these questions and more using the Audit app’s filters. These filters let you slice and dice Audit data along various dimensions such as type of service, its risk level, services used by specific users, services hosted in a particular geographical location and much more. We encourage you to explore various filtering and drill down options to see how they can show you about your company SaaS activity. Viewing summary results To view Audit results and see the top 20 SaaS applications your employees actually use: 1. In CloudSOC, select Audit, and then select Summary. Audit opens to the Summary tab as shown in the following. The Summary tab shows you your current overall Audit score, and a trend chart of your Audit score over time. The current overall Audit score is based on your Copyright © 2021 Symantec Corp. 9 Tech Note — Using the Audit App company Business Readiness Rating of every cloud service in use, weighted according to the number of users of each service, and is a value between 0 and 100. It is also dependent on your selections, such as service visibility and selected number of days. Business Readiness Rating (BRR) is a metric that the CloudSOC research team assigns to each cloud service based on a variety of criteria, such as how secure is the service. The research team also categorizes each cloud service as high risk (rating of 0 - 33), medium risk (rating of 34 - 66), or low risk (rating of 67 - 100). For more information about how cloud services are rated, see Viewing service details. The trend chart is calculated once a day at midnight, and is based on: ○ All available data sources that are not marked as "Ignored" ○ All Cloud SaaS services which are allowed traffic ○ The previous 12 months of data You can select the time range from seven days to 12 months. Use this chart to track your Audit score. Hover over a point on the curve to see the score at that point in time. Blue diamonds mark points in time at which you edited the global BRR profile. This feature lets you see when changes in the score were caused by changes to the way Audit evaluated your cloud services. The right endpoint of the curve may not match the numerical audit score, since the numerical score is based on the currently selected data sources, while the curve is based on all available sources. Copyright © 2021 Symantec Corp. 10 Tech Note — Using the Audit App The Audit Summary tab also shows you when the selected service has been involved in a recent security compromise. You can sort the Summary tab services list for compromises using the sort menu as shown in the following. You can also configure CloudSOC to reduce the BRR of any cloud service that has been compromised in the prior 90 days. The Compromised in Last 90 Days process works as follows: a. The machine learning algorithm retrieves data from multiple internet sources and identifies probable data breaches of your apps. b. Any sources flagged as being likely application data breaches are sent to reviewers in the security team. c. The reviewers analyze the available information and source to determine details such as the breach date, public notification date, responsible party, and root cause of breach. If the analysis determines a breach, then it is flagged as a breach and included in the Cloud Threat Feed functionality. The preceding process is performed multiple times a day. See Customizing service rankings for more information. Copyright © 2021 Symantec Corp. 11 Tech Note — Using the Audit App You can view the top five users and destinations for each service by clicking the service on the list. The top five users and destinations appear on the right hand side of the page. To view all users of a service, click View All above the list of service users as shown in the following. 2. To change the view to the most-used services, select Top Used Services from the menu above the services list as shown in the following.

    Cyber Security Trends: Aiming Ahead of the Target to Increase Security in 2017 A SANS Whitepaper Written by John Pescatore March 2017 Sponsored by Qualys ©2017 SANS™ Institute Introduction In security, change always equates to risk. Because change is constant, being aware of the key changes that will increase risk is a critical part of being proactive in cyber security. A simple equation for risk is the following: RISK THREAT VULNERABILITY ACTION Threats are Vulnerabilities Action consists of two malicious tactics are weaknesses components: and techniques that enable • Attacks that malicious actors (external that would cause those threats to or internal) take to launch threats damage to a succeed. business. • Prevention or mitigation efforts by security teams to reduce the attack aperture or increase speed of detection In reality, security teams control only half of the “Action” parameter. We can’t determine when threats will be developed or launched, and vulnerabilities are driven by weaknesses in people and technology. People change slowly, but technology changes rapidly, and business adoption of new technologies invariably brings new vulnerabilities that enable new threats. Understanding and anticipating business demand for emerging technologies is a key element in successful security programs. With each new wave of technology, threats tend to come in three forms: denial-of- service (DoS) attacks, cyber crime and attacks by nation-states. DoS Attacks When weaknesses in new technologies are exposed (generally by experimenters, academics and hacktivists), DoS attacks are the easiest to launch. They crash systems or cause data storms that bring networks to a halt. Cyber Crime Cyber criminals and the ecosystem that supports them refine attacks to focus on approaches that can lead to revenue, most commonly by stealing information that can be resold or support account fraud.

  • Identifying Software and Protocol Vulnerabilities in WPA2 Implementations Through Fuzzing
    POLITECNICO DI TORINO Master Degree in Computer Engineering Master Thesis Identifying Software and Protocol Vulnerabilities in WPA2 Implementations through Fuzzing Supervisors Prof. Antonio Lioy Dr. Jan Tobias M¨uehlberg Dr. Mathy Vanhoef Candidate Graziano Marallo Academic Year 2018-2019 Dedicated to my parents Summary Nowadays many activities of our daily lives are essentially based on the Internet. Information and services are available at every moment and they are just a click away. Wireless connections, in fact, have made these kinds of activities faster and easier. Nevertheless, security remains a problem to be addressed. If it is compro- mised, you can face severe consequences. When connecting to a protected Wi-Fi network a handshake is executed that provides both mutual authentication and ses- sion key negotiation. A recent discovery proves that this handshake is vulnerable to key reinstallation attacks. In response, vendors patched their implementations to prevent key reinstallations (KRACKs). However, these patches are non-trivial, and hard to get correct. Therefore it is essential that someone audits these patches to assure that key reinstallation attacks are indeed prevented. More precisely, the state machine behind the handshake can be fairly complex. On top of that, some implementations contain extra code to deal with Access Points that do not properly follow the 802.11 standard. This further complicates an implementation of the handshake. All combined, this makes it difficult to reason about the correctness of a patch. This means some patches may be flawed in practice. There are several possible techniques that can be used to accomplish this kind of analysis such as: formal verification, fuzzing, code audits, etc.

The spreader was apparently built by someone with "more advanced skills" than those that had created the original Mirai malware. This, Kaspersky Lab says, has "worrying implications for the future use and targets of Mirai-based attacks." It is richer and more robust than the original Mirai codebase, even though many of its components are "several years old." Its spreading capabilities are limited, as it can only deliver from an infected Windows host to a vulnerable Linux-powered IoT device. Even that -- if it can brute-force a remote telnet. It was also said that the author is likely Chinese- speaking, more experienced, but probably new to Mirai. "The appearance of a Mirai crossover between the Linux platform and the Windows platform is a real concern, as is the arrival on the scene of more experienced developers.

  • Is Cloudbleed Inevitable After Heartbleed? by Taiye Lambo and Jordan Flynn September 2014
    Is Cloudbleed Inevitable After Heartbleed? By Taiye Lambo and Jordan Flynn September 2014 In the technology world, vulnerabilities and bugs are commonplace. Whether an avid hobbyist or a professional working for an organization in a technical capacity, those familiar with the technology and information security space understand that there is no avoiding the inevitable discovery of vulnerabilities and bugs that must ultimately be addressed. While some of these fixes require nothing more than a simple patch job, others necessitate significant changes in policy and process within the workplace and the cautious or discontinued use of applications on mobile devices and Internet based services. With the rise in cybersecurity attacks and the continued growth of individuals storing their sensitive information online, vulnerabilities in cyberspace represent one of the most significant concerns not just for hobbyists and professionals, but also for society as a whole. The discovery of the Heartbleed bug in April 2014 made the issue of vulnerabilities and bugs in cyberspace more evident. Fundamentally, the vulnerability allows for anyone on the Internet to read and view the personal and sensitive information of others through system memory, information meant to be protected by the SSL/TLS encryption that is used to secure the vast majority of the Internet. Compounding this issue is that Heartbleed also provides the proverbial “key to the kingdom” by making the confidential keys used to properly identify service providers, and encrypt the names and passwords of users as well as actual content itself available to the criminal, allowing them to easily spy on communications and impersonate both users and services therefore stealing sensitive data directly from them.
