Many organizations are adopting Microsoft 365 (formerly Office 365) and businesses nationwide are seeing the benefits of improved productivity through its email and collaboration solution. Organizations of all sizes can benefit from a seamless user experience between mobile and on-premise environments.

While Microsoft 365 offers great flexibility, it mostly focuses on infrastructure management rather than data management. Meaning: You are responsible for your data.

Some businesses who have migrated their workloads to Microsoft 365 do not realize that the same reasons they had for backing up and protecting that data on-premises applies even in the cloud.

If you are still considering Microsoft 365 for office productivity and collaboration, this article may be for you: Microsoft 365: Is it the right choice for your business?

Without proper backup and recovery, your data is at risk, because Microsoft isn't providing complete protection. It's important to create a backup and recovery strategy to ensure you avoid permanently losing your critical data.

It's important to understand the difference in responsibilities of Microsoft and Microsoft 365 user organizations. Microsoft hosts the infrastructure, but you are responsible for your data.

What is Microsoft's Responsibility?

Cloud Infrastructure Uptime — Microsoft focuses on the infrastructure management rather than data management. By focusing on infrastructure, Microsoft ensures its cloud service is online and operational. Guaranteed uptime is based on your agreement level and outlined in the availability SLA (Service Level Agreement).

Basic Data Replication — Microsoft provides basic data replication with datacenter-to-datacenter geo redundancy, and limited retention for short-time data recovery.

Data Processing Compliance — Compliance and controls for data processing are limited to the processor, not the data itself. Microsoft ensures data privacy, regulatory controls, and industry certifications for compliance are in place and maintained for the infrastructure of its cloud service.

Physical Infrastructure Security — Security functions for Microsoft 365 are limited to physical infrastructure, not data. It includes app-level security, logical security, and access controls for users and administrators.

What is the Customer's Responsibility?

Business Data in Microsoft 365 — The customer is the owner of the data that resides in the Microsoft 365 data centers. As the owner, the customer controls the data and who can access the data. All responsibility of the data is on the user to ensure data security, privacy, and retention.

Enterprise-grade Backup and Long-Term Data Retention — Implementing an enterprise-grade backup solution for Microsoft 365 can give businesses confidence to recover from security breaches, compliance exposure, and data loss. With enterprise-grade backup, a copy of the data is stored outside the environment. In the event of an incident, it provides granular and point-in-time recovery options.

Data Owner Compliance — As the data owner, the customer has the ultimate responsibility of data for internal legal and compliance teams. The customer answers to the demands from corporate and industry regulations.

Security Functions to Protect Data — Protection of data is the responsibility of the user, not Microsoft. Security controls must be implemented to protect the data from internal threats, such as accidental deletion, insider threat, and disgruntled employees, and external threats, such as malware, ransomware, and rogue applications.

What happens when Microsoft 365 is used without backup?

Microsoft only provides basic and limited retention. If you don't implement a backup strategy outside of Microsoft's native capabilities, you are opening up your business for unnecessary risk. Lack of a Microsoft 365 backup plan is a risky data strategy.

Without proper backup and recovery, your organization can expose itself to the following risks:

  • Data loss from accidental deletions
  • Ransomware attacks and security breaches
  • Insufficient retention time for regulatory compliance policies
  • Lack of data control due to potential SaaS lock-in

Organizations investing in productivity and collaboration tools should also consider their backup and retention needs as a factor in efficiency and productivity. Considering a third-party backup solution is critical for data loss avoidance.

What is the best strategy for Microsoft 365 backup?

Your data is your business. By taking a data-driven approach to your backup strategy, you recognize the critical importance of your data for your business stability.

Make Microsoft 365 Backup a Key Priority

Backup for cloud services (SaaS), such as Microsoft 365, is imperative for security and data control. Full oversight and control of data is a boardroom priority. Without backup, organizations do not have an exit strategy or freedom from SaaS lock-in because they are not in complete control of their data. Backup should be part of the conversation when buying SaaS and not an afterthought.

Consider Enterprise-grade Data Protection

When investing in backup solutions, consider integration between the Microsoft 365 environment and your existing data protection environment. Evaluate automation, security, and integration between systems when comparing enterprise-grade data protection and recovery features. Integrating SaaS into enterprise data protection can help unify data management.

What to look for in a Microsoft 365 backup solution

1) Freedom to use existing on-premise capacity for Microsoft 365 backup, or the ability to leverage another cloud for cloud backup.
2) Basic features provided, such as incremental backups, granular recovery, automation, and policy-based retention capabilities.
3) A solution capable of managing and protecting hybrid deployments and the ability to ease the full adoption of SaaS.
4) Integration between Microsoft 365 and the customer's existing data protection environment.
5) Advanced security features such as access control, SaaS usage metrics, and multifactor authentication for additional security.
6) Ability to scale up or down as business and data demand changes and as SaaS is rolled out more widely within the company.

Microsoft has been emphasizing Office 365 (now Microsoft 365) subscription services since the public introduction in 2011. As a result, the popularity of these services has grown to over 155 million active users as of October 2018, and is gaining new users at over 3 million seats per month. With this growth, on-going marketing, and the increasing acceptance of public cloud services, many businesses and financial institutions are starting to look at Microsoft 365.

In this article, we will highlight several pros and cons of Office 365 you should consider to determine if it's right for your business.

Microsoft 365 (formerly Office 365) encompasses several different products and services, but in this article, we will address these services in two primary areas: user applications and back-end services.

Microsoft 365 User Applications

Most Microsoft 365 subscription plans include Office applications like Word and Excel running on Windows, macOS, and portable devices running iOS and Android. Applications are also available through a web browser but most customers are interested in Microsoft 365 applications as a possible replacement for traditional Office licensing.

What are the primary differences between Microsoft 365 and traditional on-premise Office applications?
  • Microsoft 365 is an annual subscription per user or seat. Each user is entitled to run the Microsoft 365 applications on up to 5 devices for the term of the subscription. As long as you continue to pay the annual subscription, you are covered for the Office applications included in your plan.
  • Office applications through Microsoft 365 are designed to be downloaded from the O365 portal. There is no license key to determine if you have a valid license. After installation the applications routinely "check in" to the M365 (formerly O365) portal to ensure there is an active account. Because of this check-in process IT administrations must use a specific procedure for mass deployment of M365 applications. Additionally, installation on multi-user servers like Remote Desktop Services and Citrix requires a new approach.
  • Microsoft 365 applications are designed to install features and security updates directly from Microsoft when they are released. Legacy patch management solutions like Windows Server Update Services (WSUS) and 3rd party solutions will not work with M365. This can create a challenge for regulated customers who are required to report on patch status. Scanning tools used by auditors to determine patch levels will need the ability to recognize the differences between M365 and traditional Office applications. The M365 update process could also create an issue for Office-integrated applications if a hotfix is released that affects the compatibility of those applications, as there will be no option to block that update from being installed.
  • Microsoft 365 applications utilize a feature called Click to Run. This feature, which was originally introduced with Office 2016, provides a streaming method for installing features and patches for Microsoft 365 and Office 2019 applications. Our experience is that Click to Run can use a significant amount of bandwidth if you are installing Office applications or large updates on multiple systems simultaneously.
Is licensing through Microsoft 365 less expensive than traditional licensing?

For most customers the biggest question is: "Is licensing through Microsoft 365 less expensive than traditional licensing?" The answer is "It depends!" Microsoft 365 licensing could be financially attractive if:

  • Your business always updates to the latest release of Office.
  • You want the flexibility of per user licensing.
  • You want to take advantage of the licensing of up to 5 devices for multiple systems, mobile devices, home use, etc.
  • You need a simplified update process that works anywhere the PC has Internet connectivity.
  • You need to use the browser-based applications for a specific function or employee role.
  • You plan to implement one of the Office 365 back-end services.

Microsoft 365 Back-End Services

Microsoft provides several cloud server applications through Microsoft 365 including Exchange Online (email), Skype for Business (voice and messaging collaboration), SharePoint (file collaboration), and OneDrive (file storage and sharing). These back-end services can be implemented individually, or as part of a bundle with or without the Office applications depending on the plan. However, Exchange Online vs. Exchange on-premise is receiving the most attention from our customers.

What should I look for when performing due diligence?

The security and compliance of back-end Microsoft 365 services is not significantly different than any other cloud-based application or service. The areas to research include:

  • External audit attestation – SSAE 18 or similar
  • Data location residency – production and failover scenarios
  • Data privacy policies - including encryption in transit and at rest
  • Contracts and licensing agreements
  • Intellectual property rights
  • Service Level Agreements – service availability, capacity monitoring, response time, and monetary remediation
  • Disaster recovery and data backup
  • Termination of service
  • Technical support – support hours, support ticket process, response time, location of support personnel
A few more things to consider...

As a public cloud service, Microsoft 365 has several challenges that need specific attention:

  • The business plans listed on the primary pricing pages may include applications or services that you don't need. All of the various features can be confusing and it's easy to pick the plan that is close enough without realizing exactly what's included and paying for services you will never use.
  • Most of the back-end M365 services can integrate with an on-premise Active Directory environment to simplify the management of user accounts and passwords. This provides a "single sign-on" experience for the user with one username and password for both local and M365 logins. Microsoft has several options for this integration but there are significant security implications for each option that should be reviewed very carefully.
  • Microsoft has published several technical architecture documents on how to have the best experience with Microsoft 365. The recommendations are especially important for larger deployments of 100+ employees, or customers with multiple physical locations. One of the notable recommendations is to have an Internet connection at each location with a next-generation firewall (NGFW) that can optimize Internet traffic for M365 applications. Redundant Internet connections are also strongly recommended to ensure consistent connectivity.
  • The default capabilities for email filtering, encryption, and compliance journaling in Exchange Online may not provide the same level of functionality as other add-on products you may be currently using. Many vendors now provide M365-integrated versions of these solutions, but there will be additional costs that should be included in the total.
  • Microsoft OneDrive is enabled by default on most Microsoft 365 plans. Similar to other public file sharing solutions like Dropbox, Box, and Google Drive, the use of OneDrive should be evaluated very carefully to ensure that customer confidential data is not at risk.
  • Several other vendors provide Microsoft 365 add-on products that provide additional functionality which may be useful for some businesses. Netwrix Auditor for Microsoft 365 can provide logging and reporting for security events in your M365 environment. Veeam Backup for Microsoft 365 can create an independent backup of your data to ensure it will always be available. Cloud Access Security Brokers (CASB) such as Fortinet FortiCASB and Cisco Cloudlock can provide an additional layer of security between your users and cloud services such as M365.

Discover why the default retention policies of Microsoft 365 can leave your business at risk.

It is certainly a challenge to research and evaluate cloud solutions like Microsoft 365. Financial institutions and other regulated businesses with high-security requirements have to take a thorough look at the pros and cons of any cloud solution to determine if it's the best fit for them.

CoNetrix Aspire has been providing private cloud solutions for businesses and financial institutions since 2007. Many of the potential security and compliance issues with the public cloud are more easily addressed in a private cloud environment when the solution can be customized for each business.

The combination of Office application licensing with back-end services like Exchange Online can be a good solution for some businesses. The key is to understand all of the issues related to Microsoft 365 so you can make an informed decision.

CoNetrix recently assisted two customers with targeted phishing attacks in which the attackers attempted to redirect wire transfers. This activity is not new, however, some of the tactics utilized in the attack are noteworthy and provide insight into how organizations can better protect themselves.

How did the attackers gain entry into corporate accounts? 

The entry point for the attackers was corporate email accounts that were exposed to the Internet and accessed using a web browser. The email accounts of the victims were compromised by guessing passwords or reusing previously-compromised passwords. Once access was gained to the email accounts, mailbox rules were configured to direct emails about wire transfers to the "RSS Feeds" folder. This effectively hid the email messages from the victim, while allowing the attacker access to them.

Next, the attacker sent email messages from a domain name similar to the domain name of the compromised email account. The fake messages said the previous email messages concerning money transfers were in error and provided different destination bank routing and account numbers where the money would be accessible by the attackers.

Take steps to mitigate the risks of phishing attacks 

In these cases, the fraudulent email messages were noticed by the recipients and the attacks failed. However, these attacks are routinely successful, and it is necessary to take steps to mitigate the risk, especially when corporate email accounts are accessible using a web browser (e.g. Office 365, Outlook Web Access (OWA), cloud-hosted email, any email account that can be logged into using a web browser and public Internet access).

  • Review your organization's email services to see if Internet-facing email access is enabled. One way to do this is to ask the question, "can we log in to our email accounts using a web browser from any Internet connection (e.g. a coffee shop, at home, at a hotel)?"
  • If Internet-facing email access is enabled disable access for employees who do not need it.
  • For employees who need Internet-facing email access, enable dual-factor authentication.
  • Look for inbox forwarding or redirect rule changes. Logging for these changes can be enabled in the email system's administrative console.
  • On firewall or intrusion prevention devices, enable rules to block traffic that is sourced from countries where known malicious traffic originates.
  • Utilize security event monitoring technologies to monitor web server logs for abnormal login activity.
  • Do not rely solely on email or other electronic communications for initiating or modifying financial transactions. Implement out-of-band approval procedures such that financial transactions and changes to financial processes must be verified using a different form of communication. For example, if a request to change a receiving bank account number is initiated via email, it must be verified via a phone call to a number that is already on file.

Early this year the tech world was rocked with the announcement of two unprecedented vulnerabilities named Meltdown and Spectre.

These two vulnerabilities are a big deal because they are hardware vulnerabilities affecting any device with a silicon chip. This includes microprocessors on workstations and servers, mobile phones, tablets, cloud services, and other platforms.

Understandably there was a rush from three main industries, processor companies, operating system companies, and cloud providers to provide solutions. However, as a result of the urgent response, there were unanticipated update incompatibilities which crashed systems. This created a dilemma for IT professionals. "Do we install updates which may cause our systems to crash?" or "Do we sit-tight and remain vulnerable?"

Even in the weeks of uncertainty, there were calm voices of seasoned reasoning. Their message reminded us that basic security standards remain our first line of defense. No matter how bad an exploit may be, its impact can be limited if:

  • The vulnerability doesn't have access to your systems
  • Operating system or application weaknesses are patched
  • Security software is installed (advanced end-point protection software with artificial intelligence is a game changer)

So how do you do achieve these standards? Here are some fundamental best practices:

  1. Monitor availability of operating system and application updates. Be sure you find and establish good sources to inform you about the patches and updates for your systems and applications. Then, monitor the sources or subscribe to notifications.

  2. Test updates to ensure compatibility. It is best if your update and patching process includes a test environment where non-production systems are updated first in order to test functionality and compatibility. This allows you to postpone or avoid updates which might crash systems or applications.

  3. Apply updates and patches on a regular schedule. As a best practice, you should implement a schedule (at least monthly) to evaluate, test and install updates for systems and critical applications. In this way, your schedule can coincide with schedules of operating system and application vendors (e.g., Microsoft has "Patch Tuesday, the second Tuesday of each month).

  4. Install and maintain security software (e.g., antivirus software, endpoint security software, etc.). If possible, explore and utilize behavior based end-point protection software. This genre of software "watches" system behavior to notice and stop suspicious action.

  5. Prevent malicious code execution. The goal is to keep malicious code out of your network and systems. This is best accomplished with layers of security including Internet filtering, phishing detection, and security awareness training for system users. Security awareness is essential to help prevent users from falling prey to malicious emails.
