The novel aspects of WannaCry and Petya were not skills as ransomware, but the combination of commonplace <a href="https://www.microsoft.com/en-us/wdsi/threats/ransomware">ransomware</a> tactics paired with worm capability to improve propagation.</p>&#10;<p><a href="https://blogs.technet.microsoft.com/mmpc/2017/05/12/wannacrypt-ransomware-worm-targets-out-of-date-systems/">WannaCry</a> achieved its saturation primarily through exploiting a discovered and patched vulnerability in a common Windows service. The vulnerability (<a href="https://technet.microsoft.com/en-us/library/security/ms17-010.aspx">MS17-010</a>) impacted the Windows Server service which enables communication between computers using the SMB protocol. Machines infected by WannaCry propagate by connecting to a nearby unpatched machine, performing the exploit, and executing the malware. Execution of the exploit did not require authentication, thus enabling infection of any unpatched machine.</p>&#10;<p><a href="https://blogs.technet.microsoft.com/mmpc/2017/06/27/new-ransomware-old-techniques-petya-adds-worm-capabilities/">Petya</a> took this worming functionality one step further and additionally introduced credential theft and impersonation as a form of worming capability. These techniques target single sign-on technologies, such as traditional domain membership. This added capability specifically targeted enterprise environments and enabled the malware to use a single unpatched endpoint to springboard into the network, then used active sessions on the machine to infect other machines regardless of patch level. To an enterprise, a single unpatched endpoint paired with poor credential hygiene could be used to enable propagation throughout the enterprise.</p>&#10;<p>Most impersonation and credential theft attacks are possible only when malware obtains local administrator or equivalent authorization to the operating system. For Petya, this would mean successful exploitation of MS17-010, or running under the context of a user with local administrator authorization.</p>&#10;<h3>Measuring the value of a user account</h3>&#10;<p>To a hacker, an infected or stolen identity is measurable in two ways: the breadth of computers that trust and grant authorization to the account and the level of authorization granted upon successful authentication. Since encryption can be performed by any user account, ransomware benefits most when it infects an account which can convey write authorization to a large amount of data.</p>&#10;<p>In most cases (thus far), the data sought out by ransomware has been either local files or those accessible over a network attached share data which can be accessed by the malware using out-of-the-box operating system interfaces. As such, data encrypted by most ransomware includes files in the users profile, home directory, or on shared directories where the user has access and write authorization.</p>&#10;<p>In the case of WannaCry, the identity used by the ransomware was SYSTEM an effectively unrestricted account from an authorization perspective. Running as SYSTEM, WannaCry had authorization to encrypt any file on the infected machine.</p>&#10;<p>Petyas encryption mechanism <a href="https://blogs.technet.microsoft.com/mmpc/2017/06/27/new-ransomware-old-techniques-petya-adds-worm-capabilities/">required the ability to overwrite the boot sector</a> of the hard drive to invoke its encryption mechanism. The malware then creates a scheduled task to restart the machine at least 10 minutes later to perform the encryption. The offline encryption mechanism prevented destruction of network files by Petya.</p>&#10;<h3>Infected machines and worms</h3>&#10;<p>Pivoting our focus to the worm aspect of these ransomware variants, the value of an infected host to a hacker is measurable in two ways: the quantity of newly accessible targets resulting from infection and the data which now becomes available because of the infection. Malware with worming capability focuses on widespread propagation, thus machines which can access new targets are highly valuable.</p>&#10;<p>To both WannaCry and Petya, a newly infected system offered a means to access previously inaccessible machines. For WannaCry, any potential new targets needed to be vulnerable to MS17-010. Vulnerability gave both malware variants SYSTEM-level authority, thus enabling successful execution of their payload.</p>&#10;<p>Additionally, in the case of Petya, any machine having reusable credentials in memory furthered its ability to propagate. Petya searches for active sessions on an infected machine and tries to use the session to infect machines which may not have been vulnerable to MS17-010. As a result, a single vulnerable endpoint may expose a reusable administrative credential usable to infect potential targets which grant that credential a necessary level of authorization.</p>&#10;<h3>Codifying the vulnerability</h3>&#10;<p>To defend against a ransomware application with worm capability we need to target the following areas:</p>&#10;<ul>&#10;<li>Ransomware&#10;<ul>&#10;<li>Reduce the authorization level of users relative to the operating system of an infected machine</li>&#10;<li>Perform backups or versioning of files to prevent loss of data due to encryption, deletion, or corruption</li>&#10;<li>Limit authorization to delete or tamper with the data backups</li>&#10;</ul>&#10;</li>&#10;<li>Worms&#10;<ul>&#10;<li>Reduce the ability for an infected host to access a potential infection target</li>&#10;<li>Reduce the number of remotely exploitable vulnerabilities that provide remote code execution</li>&#10;<li>Reduce exposure of reusable credentials relative to the likelihood of a host to compromise</li>&#10;</ul>&#10;</li>&#10;</ul>&#10;<h2>Resolving Concerns through design</h2>&#10;<p>Many of the risks associated with ransomware and worm malware can be alleviated through systems design. Referring to our now codified list of vulnerabilities, we know that our solution must:</p>&#10;<ul>&#10;<li>Limit the number (and value) of potential targets that an infected machine can contact</li>&#10;<li>Limit exposure of reusable credentials that grant administrative authorization to potential victim machines</li>&#10;<li>Prevent infected identities from damaging or destroying data</li>&#10;<li>Limit unnecessary risk exposure to servers housing data</li>&#10;</ul>&#10;<h3>Windows 10, BYOD, and Azure AD Join</h3>&#10;<p>Windows 10 offers a new management model that differs significantly from traditional domain joined machines. Azure Active Directory joined machines can still convey identity to organizational resources; however, the machine itself does not trust domain credentials. This design prevents reusable accounts from exposure to workstations, thus protecting the confidentiality of the credential. Additionally, this limits the impact of a compromised domain account since Azure AD joined machines will not trust the identity.</p>&#10;<p>Another benefit of Windows 10 with Azure AD is the ability to move workstations outside of the firewall, thus reducing the number of potential targets once infection occurs. Moving endpoints outside the firewall reduces the impact of any workstation threat by reducing the benefits normally gained by compromising a machine within the corporate firewall. As a result, this design exposes fewer server ports to potentially compromised endpoints, thus limiting the attack surface and reducing the likelihood of worm propagation.</p>&#10;<p>Moving workstations outside of the firewall offers added security for the workstation as well. Migrating to a BYOD architecture can enable a more stringent client firewall policy, which in turn reduces the number of services exposed to other hosts, and thus improves the machines defense against worms and other inbound attacks.</p>&#10;<p>Additionally, most organizations use many laptops which often connect from untrusted locations outside the firewall. While outside of the firewall, these machines can connect to untrusted sources, become infected, then bring the infection inside the firewall next time it is able to connect to the internal network. This causes confusion when trying to identify the initial infection during an incident response, and potentially exposes the internal network to unnecessary risk.</p>&#10;<h3>Consider migration file shares to OneDrive or Office365</h3>&#10;<p>Migrating data from traditional file shares into a solution such as SharePoint or OneDrive can limit the impact of a ransomware attack. Data stored in these technologies can enforce version control, thus potentially simplifying recovery. To further protect this data, limit the number of SharePoint users who had administrative authority to the site to prevent emptying of the recycle bin.</p>&#10;<h3>Ensure resilient backups</h3>&#10;<p>When an attack occurs, it is crucial to <a href="https://blogs.technet.microsoft.com/mmpc/2017/03/28/world-backup-day-is-as-good-as-any-to-back-up-your-data/">ensure ransomware cannot destroy data backups</a>. Although convenient, online data backups may be subject to destruction during an attack. Depending on design, an online backup solution may trust a stolen reusable single sign-on credential to enable deletion or encryption of backup data. If this occurs, backups may be rendered unusable during the attack.</p>&#10;<p>To prevent against this, consider Azure Cloud Backup a secure off-site backup solution. Azure Cloud Backup is managed through the Azure Portal which can be configured to require separate authentication, to include multi-factor authentication. Volumes used to store backup data reside in Azure and cannot be initialized or overwritten using on-premises domain credentials.</p>&#10;<h2>Closing</h2>&#10;<p>Windows 10 and BYOD architecture offers significant defense against a variety of cyberattacks, to include worms and ransomware. This article covers only some of the protections that Windows 10 offers against credential theft, bootkits, rootkits, and other malware techniques employed by this class of highly destructive malware.</p>&#10;<p>To better defend your organization against future malware outbreaks:</p>&#10;<ul>&#10;<li>Prepare to migrate client machines to <a href="https://docs.microsoft.com/en-us/windows/deployment/planning/">Windows 10</a></li>&#10;<li>Plan for BYOD device management using <a href="https://docs.microsoft.com/en-us/windows/client-management/manage-windows-10-in-your-organization-modern-management">Microsoft Intune</a> and <a href="https://docs.microsoft.com/en-us/azure/active-directory/device-management-introduction">Azure AD joined machines</a></li>&#10;<li>Implement <a href="https://docs.microsoft.com/en-us/azure/backup/backup-azure-microsoft-azure-backup">Azure Backup</a> to provide a resilient and malware-resistant backup solution</li>&#10;<li>Learn how <a href="https://docs.microsoft.com/en-us/windows/threat-protection/windows-defender-atp/windows-defender-advanced-threat-protection">Windows Defender Advanced Threat Protection (ATP)</a> can help your organization quickly detect and respond to malware outbreaks</li>&#10;</ul>&#10;]]></content:encoded> </item> <item> <title>Learn from leading cybersecurity experts</title> <link>https://cloudblogs.microsoft.com/microsoftsecure/2017/10/26/learn-from-leading-cybersecurity-experts/</link> <pubDate>Thu, 26 Oct 2017 16:00:28 +0000</pubDate> <dc:creator><![CDATA[Microsoft Secure Blog Staff]]></dc:creator> <category><![CDATA[Uncategorized]]></category> <guid isPermaLink="false">https://cloudblogs.microsoft.com/microsoftsecure/?p=74758</guid> <description><![CDATA[More than 170K technology and business leaders from across the world depend on Microsofts Modern Workplace monthly webcast to shed new light on business challenges related to technology.

Over the past four years, Modern Workplace has had the worlds leading experts share their advice on technology topics, such as security, including CISOs, Chief Privacy Officers, Cyber Intelligence Advisors, and Chief Digital Officers. Just in the past year, Modern Workplace security episodes included:</p>&#10;<ul>&#10;<li><a href="https://resources.office.com/ww-landing-modern-workplace-ep307.html">Cyber Intelligence: The Human Element</a> (covering Identity and Access Management)</li>&#10;<li><a href="https://resources.office.com/modern-workplace-webinar-registration-306.html">Cyber Intelligence: Help Prevent a Breach</a> (covering Threat Protection)</li>&#10;<li><a href="https://resources.office.com/modern-workplace-webinar-registration-302.html">The Privacy Balance: Staying Secure and Ethical with Your Data</a> (covering Information Protection)</li>&#10;<li><a href="https://resources.office.com/modern-workplace-webinar-registration-301.html">Data Defense: An Inside Look at Your Secure Cloud</a> (covers Security Management)</li>&#10;</ul>&#10;<p>These episodes include more than just security checklists and basicsthey go into depth around the decisions business leaders are faced with every day. In the episode on data privacy, Hillery Nye, Chief Privacy Officer at Glympse, explained how the startup company made a very conscious decision to not collect data that it could have easily gathered from its real-time location sharing app. The company collects customer data and uses it for very specific purposes, but it never stores or sells that data. The company may have given up some opportunities to monetize its customer data, but Nye feels that the company gains even more by being a responsible corporate citizen and establishing a reputation for privacy. She discussed how a companys brand is affected by its privacy policies, and how businesses can better align their privacy policies with business strategy for long term success.</p>&#10;<p>The Modern Workplace series has been nominated for four regional Emmy awards because of its creative presentation of diverse perspectives and insights.

In the flurry of headlines and advice about credit freezes an important part of the conversation was lost: if we didnt misuse our social security numbers, losing them wouldnt be a big deal. Let me explain: most people, and that mainly includes some pretty high-up identity experts that Ive met in my travels, dont understand the difference between identification and verification. In the real world, conflating those two points doesnt often have dire consequences. In the digital world, its a huge mistake that can lead to severe impacts.</p>&#10;<p>Isnt it all just authentication you may ask? Well, yes, identification and verification are both parts of the authentication whole, but failure to understand the differences is where the mess comes in. However, one reason its so hard for many of us to separate identification and verification is that historically we havent had to. Think back to how humans authenticated to each other before the ability to travel long distances came into the picture. Our circle of acquaintances was pretty small and we knew each other by sight and sound. Just by looking at your neighbor, Bob, you could authenticate him. If you met a stranger, chances are someone else in the village knew the stranger and could vouch for her.</p>&#10;<p>The ability to travel long distances changed the equation a bit. We developed documents that provided verification during the initiation phase, for example when you have to bring a birth certificate to the DMV to get your initial drivers license. And ongoing identification like a unique ID and a photo. These documents served as a single identification and verification mechanism. And that was great! Worked fine for years, until the digital age.</p>&#10;<p>The digital age changed the model because rather than one person holding a single license with their photo on it, we had billions of people trying to authenticate to billions of systems with simple credentials like user name and password. And no friendly local villager to vouch for us.</p>&#10;<h2>Who are you? Prove it!</h2>&#10;<p>This is where the difference between the two really starts to matter. Identification answers the question: Who are you? Your name is an identifier. It could also be an alias, such as your unique employee ID number.</p>&#10;<p>Do you want your name to be private? Imagine meeting another parent at your kids soccer game and refusing to tell them your name for security reasons. How about: Oh your new puppy is so adorable, whats her name? And you respond, If I told you, Id have to kill you. Or you try to find an address in a town with no street signs because the town is super security conscious. Ridiculous, right? Identifiers are public specifically so we can share them to help identify things.</p>&#10;<p>We also want consistency in our identifiers. Imagine if that town had street signs, but changed the names of the streets every 24 hours for security reasons. And uniqueness, if every street had the same name, youd still have a heck of a time finding the right address wouldnt you?</p>&#10;<p>Now that were clear on what the identifier is, we can enumerate a few aspects that make up a really good one:</p>&#10;<ul>&#10;<li>Public</li>&#10;<li>Unchanging</li>&#10;<li>Unique</li>&#10;</ul>&#10;<p>In a town or public road, we have a level of trust that the street sign is correct because the local authorities have governance over road signs. Back in our village, we trust Bob is Bob because we can verify him ourselves. But in the digital world, things get pretty tricky how do you verify someone or something youve never met before? Ask them to- Prove It!</p>&#10;<p>We use these two aspects of authentication almost daily when we log into systems with a user ID (identification) and password (verification). How we verify in the real world can be public, unchanging, and unique because its very hard to forge a whole person. Or to switch all the street signs in a town. But verification online is trickier. We need to be able toprovide verification of who we are to a number of entities, many of whom arent great at protecting data. And if the same verification is re-used across entities, and one loses it, attackers could gain access to every site where it was used. This is why experts strongly recommend using unique passwords for every website/app. This goes for those challenge questions too. Which can lead to some fun calls with customer service, Oh, the town where I was born? Its: xja*21njaJK)`jjAQ^. At this point in time our fathers middle name, first pets name, town where we were born, school we went to and address history should be assumed public, using them as secrets for verification doesnt make sense anymore.</p>&#10;<p>If one site loses your digital verification info, no worries. You only used it for that site and can create new info for the next one. What if you couldnt change your password ever? It was permanent and also got lost during the Yahoo! breach? And it was the one you use at your bank, and for your college and car loans, and your health insurance?

As digital transformation sweeps the globe, the imminent threat of cybercrime grows alongside it. As a result, new techniques in cybersecurity must be developed at a growing rate to keep pace.</p>&#10;<p>Digital-first is the new business frontier, and if we want to keep this landscape a safe space to store and share information, we must be able to quickly identify opportunities to bolster security and adapt to evolving threats. Microsofts cloud technology offers organizations the tools to advance security, enhance government compliance, improve security education, and enable industry collaboration to shut down new threats. Microsoft is creating a new path toward digital transformation in a secure space.</p>&#10;<p>Through cloud technologies, IT professionals now have advanced tools at their fingertips that provide real-time visibility into cybersecurity and the ability to proactively thwart threats before they become an issue. As more organizations move to the cloud, management of security risks can occur in real time. This real-time action on cyber threats helps create cost efficiency, and allows for frequent and seamless updates without reconfiguration, giving IT leaders the upper hand in staying compliant with regulatory guidelines.</p>&#10;<p>With cloud-based technology come real solutions in data loss prevention. IT professionals are using the cloud to secure employee data in new and highly effective ways. Through improved cloud encryption capabilities, organizations can better help protect sensitive information in motion and at rest. Even if cybercriminals are able to breach your network and bypass the first lines of cyber defense, <a href="https://www.microsoft.com/en-us/trustcenter/security/encryption">encryption helps keep organizational data from falling into unauthorized hands</a>. Additionally, advanced measures like multi-factor authentication (MFA) and Single Sign-On (SSO) provide additional layers of security by ensuring only those with the proper credentials are able to gain access to information and company platforms. These solutions and innovations in tech security are just the beginning.</p>&#10;<p>With the advent of new technology and the digitization of how IT experts and professionals communicate, a quicker dissemination of knowledge can occur in a collaborative space. Experts can share and explore new ideas and concepts to quickly improve upon cloud technology and how to best address security concerns. By partnering up, industries are able to break new ground on how to secure information, share information, and revolutionize the way government, private enterprise, education systems, and average people navigate a digitally transforming world.</p>&#10;<p>Ready to discover how Microsoft technology is transforming security for a digital-first, cloud-first world, and participate in interactive sessions led by subject matter experts? Microsoft is hosting a series of Security Forums in cities across the United States to demonstrate how organizations can use the latest technology to update and improve their cybersecurity efforts. We invite you to join your fellow IT professionals alongside Microsoft experts to discuss new ways to address evolving cyber threats.

To make it easier for Microsoft customers to deploy secured virtual machines out of the box, I am excited to share the recent availability for purchase of hardened virtual machine images within Azure, based on the partnership between Microsoft and the <a href="https://www.cisecurity.org/">Center for Internet Security</a>(CIS). CIS is a non-profit entity focused on developing global standards and recognized best practices for securing IT systems and data against the most pervasive attacks. Hardened images are virtual machine images that have been hardened, or configured, to be more resilient to cyber attacks. These images are available in the <a href="https://azuremarketplace.microsoft.com/">Azure Marketplace</a> and can be used by Azure customers to create new, securely configured virtual machines.</p>&#10;<p>Establishing and maintaining the secure configuration of an entitys IT infrastructure continues to be a core tenet of information security. History has shown that the misconfiguration or poor configuration of laptops, servers, and network devices is a common cause of data breaches. Global standards, governments, and regulatory bodies have also highlighted the importance of establishing and maintaining secure configurations, and in many cases, have mandated their use due to their effectiveness. I have included a few of the most relevant and wide-ranging examples in the table below.</p>&#10;<table style="height: 226px" width="980">&#10;<tbody>&#10;<tr>&#10;<td width="208"><strong>Source</strong></td>&#10;<td width="236"><strong>Control</strong></td>&#10;<td width="180"><strong>Reference</strong></td>&#10;</tr>&#10;<tr>&#10;<td width="208">Center for Internet Security Critical Security Controls</td>&#10;<td width="236">CIS Control 3 Secure configurations for hardware and software on mobile devices, laptops, workstations, and servers</td>&#10;<td width="180"><a href="https://www.cisecurity.org/controls/secure-configurations-for-hardware-and-software/">https://www.cisecurity.org/controls/secure-configurations-for-hardware-and-software/</a></td>&#10;</tr>&#10;<tr>&#10;<td width="208">Australian Signals Directorate Strategies to Mitigate Cyber Security Incidents</td>&#10;<td width="236">User Application Hardening<br />&#10;Server Application Hardening<br />&#10;Operating System Hardening</td>&#10;<td width="180"><a href="https://www.asd.gov.au/infosec/mitigationstrategies.htm">https://www.asd.gov.au/infosec/mitigationstrategies.htm</a></td>&#10;</tr>&#10;<tr>&#10;<td width="208">US NIST Cyber Framework</td>&#10;<td width="236">PR.IP-1: A baseline configuration of information technology/ industrial control systems is created and maintained</td>&#10;<td width="180"><a href="https://www.nist.gov/sites/default/files/documents/cyberframework/cybersecurity-framework-021214.pdf">https://www.nist.gov/sites/default/files/documents/cyberframework/cybersecurity-framework-021214.pdf</a></td>&#10;</tr>&#10;<tr>&#10;<td width="208">Payment Card Industry</td>&#10;<td width="236">Build and maintain a secure network and systems</td>&#10;<td width="180"><a href="https://www.pcisecuritystandards.org/documents/PCIDSS_QRGv3_2.pdf?agreement=true&amp;time=1505339723255">https://www.pcisecuritystandards.org/documents/PCIDSS_QRGv3_2.pdf?agreement=true&amp;time=1505339723255</a></td>&#10;</tr>&#10;</tbody>&#10;</table>&#10;<h2>Accessing and Deploying CIS Hardened Images</h2>&#10;<p>To view the CIS hardened images, login to the Azure portal and navigate to the Marketplace. You can then search for and filter on the Center for Internet Security. As you can see below, there are hardened images for many of the common operating systems, including Windows Server 2012, Oracle Linux, and Windows Server 2016.</p>&#10;<p><img class="size-large wp-image-70516 aligncenter" src="https://cloudblogs.microsoft.com/microsoftsecure/wp-content/uploads/sites/13/2017/10/Accessing-and-Deploying-CIS-Hardened-Images_1-1024x700.png" alt="" width="1024" height="700" srcset="https://cloudblogs.microsoft.com/microsoftsecure/wp-content/uploads/sites/13/2017/10/Accessing-and-Deploying-CIS-Hardened-Images_1-1024x700.png 1024w, https://cloudblogs.microsoft.com/microsoftsecure/wp-content/uploads/sites/13/2017/10/Accessing-and-Deploying-CIS-Hardened-Images_1-300x205.png 300w, https://cloudblogs.microsoft.com/microsoftsecure/wp-content/uploads/sites/13/2017/10/Accessing-and-Deploying-CIS-Hardened-Images_1-768x525.png 768w, https://cloudblogs.microsoft.com/microsoftsecure/wp-content/uploads/sites/13/2017/10/Accessing-and-Deploying-CIS-Hardened-Images_1.png 1431w" sizes="(max-width: 1024px) 100vw, 1024px" /></p>&#10;<p>From within the Marketplace blade, you can then select the appropriate image and select the create button to start the deployment journey within the portal or gain further details on deploying the image programmatically.

This will cause the object in question to become invisible (not be returned in LDAP queries performed to the Active Directory), which causes the object to avoid being seen (and monitored) by any service account used by monitoring solutions.</p>&#10;<p>This does sound like an issue, as denying permissions from a Domain Admin principle (or the <em>Everyone</em> principle for that matter) will cause an object to become invisible. A cool idea indeed.</p>&#10;<p>So, this made me think is there a way we can identify <em><strong>all</strong></em> the objects to which I <strong>dont</strong> have permissions?</p>&#10;<p>Sounds like a tough task, however after going through some of the possible resolution APIs together with the ATA security research team, <a href="https://twitter.com/simakov_marina">Marina</a> has come across this statement for the LsaLookupSIDs:</p>&#10;<p style="padding-left: 30px"><em><a href="https://technet.microsoft.com/en-us/library/ff428139%28v=ws.10%29.aspx#BKMK_LsaLookupSIDs">There is no access check that would require the caller to be able to read the SID or account name to perform the mapping</a>.</em></p>&#10;<p>Now that weve found a method to query a SID and get a result regardless of the ACL we can verify whether the object exists or not.</p>&#10;<p>The next step is to identify whether its a permissions issue. In order to validate whether its a permissions issue or not, we can compare the results of this API with the LDAP query results.</p>&#10;<p>If <em><strong>only</strong></em> the LsaLookupSIDs returns a result while the LDAP query fails this means one thing (after cleaning up several bugs related to SidHistory) <strong>we dont have permissions on the objec</strong>t!</p>&#10;<p>Ive made a small PowerShell script to demonstrate this capability. The script enumerates all RIDs in a specific domain and compares the LDAP result to the LsaLookupSIDs result to see what I am missing.</p>&#10;<p>The script can be found at <a href="https://github.com/michdu/WhatAmIMissing">https://github.com/michdu/WhatAmIMissing</a>.</p>&#10;<p>This should make discovering ACL hidden objects a little bit easier.</p>&#10;]]></content:encoded> </item> <item> <title>SharePoint and OneDrive: security you can trust, control you can count on</title> <link>https://cloudblogs.microsoft.com/microsoftsecure/2017/10/10/sharepoint-and-onedrive-security-you-can-trust-control-you-can-count-on/</link> <pubDate>Tue, 10 Oct 2017 19:00:19 +0000</pubDate> <dc:creator><![CDATA[Microsoft Secure Blog Staff]]></dc:creator> <category><![CDATA[Uncategorized]]></category> <guid isPermaLink="false">https://cloudblogs.microsoft.com/microsoftsecure/?p=70447</guid> <description><![CDATA[This post is authored by Bill Baer, Senior Product Marketing Manager, SharePoint and OneDrive Team.

We draw from this experience to keep making SharePoint and OneDrive more secure for users, by implementing and continuously improving security-aware software development, operational management, and threat-mitigation practices that are essential to the strong protection of your services and data.</p>&#10;<p>SharePoint and OneDrive are uniquely positioned to help you address these evolving security challenges. To begin with, Microsoft has continued to evolve with new standards and regulations. This has been a guiding principle as we think about security for SharePoint and OneDrive. Right alongside that principle is this one: There is no security without usability. If security gets in the way of productivity, users will find a different, less secure way to do their work.</p>&#10;<p>SharePoint and OneDrive allow your organization to go beyond its regular business rhythms and be nimbler in responding to market changes and opportunities. These solutions enable users to access the files and documents they need wherever they&#8217;re doing work while sharing and collaborating in real-time. And you control and own your data while Microsoft takes care of it. <a href="http://sharepoint-infographic.azurewebsites.net/">Explore</a> the many options SharePoint and OneDrive provide to secure you and your information and then read our eBook <em><a href="https://www.microsoft.com/en-us/download/details.aspx?id=55242">Securing your content in the new world of work with SharePoint and OneDrive</a>.</em></p>&#10;<p>For businesses, the time is now to reevaluate security practices. In the modern communications and collaboration, landscape connectivity is ubiquitous and the ability to work remotely has become an ingrained part of the work practice. People have come to expect to be able to access email and documents from anywhere on any device &#8211; and for that experience to be seamless.</p>&#10;<p>While this has been an enormous boost to productivity, it also presents huge challenges for security. Previously, businesses needed to concern themselves with a firewall that ended at the corporate boundary. Now that boundary has shifted to the end user. Businesses need to ensure sure that corporate data is safe while enabling users to stay productive in today&#8217;s mobile-first world, where the threat landscape is increasingly complex and sophisticated.</p>&#10;<p>We know that data loss is non-negotiable, and overexposure to information can have legal and compliance implications. SharePoint and OneDrive provide a broad array of features and capabilities designed to make certain that your sensitive information remains that way with investments across our security and compliance principles to include compliance tools that span on-premises servers and Office 365 while providing a balance between enabling user self-service.</p>&#10;<p>The rapidly-changing security landscape means that your organization&#8217;s content &#8211; its knowledge &#8211; is being shared more broadly, and accessed from more devices and more locations, than ever before. We&#8217;re committed to the security, privacy, and compliance of your data, and we continuously innovate intelligent ways to protect your content and to empower you to govern and manage information. Last month we announced label-based classification for information management policies, which enable a more dynamic governance of content across SharePoint, Exchange, and Skype, and Microsoft Teams. We&#8217;re continuously working to ensure content usage adheres to corporate policy defending your organization from todays growing and evolving advanced threats.</p>&#10;<p>To learn more about security and compliance with SharePoint and OneDrive:</p>&#10;<ul>&#10;<li><a href="https://www.microsoft.com/en-us/download/details.aspx?id=53884">Read more about how we secure your files</a></li>&#10;<li><a href="https://products.office.com/en-us/business/office-365-trust-center-welcome?legRedir=true&amp;CorrelationId=de8d945b-65d3-41bc-b5a5-41d503131554">Review Office 365 Trust where we share our commitments and information about security, privacy, and compliance</a></li>&#10;<li>Stay up to date with our <a href="https://blogs.office.com/security/">security</a> and <a href="https://blogs.office.com/compliance/">compliance</a> blogs</li>&#10;</ul>&#10;]]></content:encoded> </item> </channel> </rss>
