Are you making plan to move your work in Office 365 email client? Or have just did that? But while doing all this have you considered security risks on cloud? No? Don’t worry, here we are to address all cloud access security concerns that need to keep in mind while transferring outlook emails to office 365.
Migrating security factors of cloud applications demand more specific planning and deep knowledge about product-based obstacles. Microsoft research states that around 35% of the MS Exchange users base is prepared with Office 365 migration. Several other enterprises will make the switch from one platform to Microsoft cloud-based products in coming months.
It is the truth that each and every migration comprises of several risks. But, none of the IT employees want to be the part of dramatic outage, business disruptions, or productivity losses. So, considering all the factors from the side of business owners and employees, we designed this blog. This will provide Office 365 cloud security checklist while migrating in Office 365 tenants.
Security Concern 1: Extra On-premises Security Methods
It is true that several benefits will be offered while migration to the cloud but, enterprises who are already long-term customers with Microsoft services legacy have to face few amounts of redundancy. The already available data protection measures, backup, and the servers might be under unnecessary post-migration category.
This leads to gap in Office 365 enterprise cloud security. Not only while moving to Office 365 but, also other migrations should comprise a complete assessments list. This list should involve that how will you manage compliance requirements and challenges along with the technical approaches like data integrity analyzing the application for determining emerging vulnerabilities.
Security Concern 2: Limits of Applicable Protection Offerings
A number of security concerns can be addressed and permitted to upgrade inherent Office product’s security by the Exchange Online Protection. It provides protection against several spam and malware forms, comprising suspicious attachments as well. But, in trending cybercrimes, this EOP is not sufficient to render safety of Office 365 that comprises of prevention from highly-targeted attacks like phishing and whaling, malicious software, and other identical ways to deliver threats.
The Exchange online protection and other signature-based detection forums are dependent on already existing data sets of popular threats. They do not role like a sufficient prevention technique against a unique, customized, or unpredictable attack.
Security Concern 3: Absence of Multi-Layer Protection
EOP is a single-layered idea to filter out the malicious documents and emails. At the time of moving to Office 365, if any of the malicious data escapes from filtration process, there is no chance to protect upcoming disaster.
Exchange online protection’s sole reliance renders a protective environment but, disable the cloud security professionals to determine or fix threats that have acquired illegal access in your environment. Well, EOP is effective to filter several malicious emails and its attachments, it is not an application for multi-layered security.
Security Concern 4: Office 365 Data Protection Compliance
Basic requirements of Microsoft Office 365 security compliance might vary in a significant manner. These demands need to be described in a simple and best way to consult with general counsels. But prior to the process of moving to Office 365, it is essential to identify the measures to prevent eDiscovery archives and relevant laws for data retention policy.
No robust information capabilities are provided by Exchange Online archiving but, it is compulsory to completely assess either a fully compliant in all involved areas, which your firm operates or less. In addition to this, EOA might not retain archives of pre-migration in a scenario, which is compliant along with requirements of your enterprise.
Security Concern 5: Office 365 Data Loss
Information resiliency should be an important part in the planning of migration and risk mitigation while working with any of the cloud-based application. If the cloud-based Office applications should move downward, your firm requires the capability of data restoration to an earlier state. This is needed with full oversight of modifications, which occurs while moving downwards. In an optimal manner, you should gain solutions for business continuity, which comprises of archived as well as post-transition content.
Observational Verdict
Moving to Office 365 could yield few aspects of security and help businesses in their growth through access control in cloud computing technology. This includes prevention of Exchange Online Archival and Protection. However, enterprises should be aware of the risks that are associated with source and destination email client migrations to convert OST file to office 365. They should be known from limitations of any signature-based measures and understand that how your enterprise moves away from the legacy security that impacts existing cloud access security.
