Wie können Sie Ihre IT-Services in einer Bring-Your-Own-Device-Umgebung absichern?

A comprehensive BYOD policy not only mitigates security risks but also fosters a culture of responsibility and accountability among employees. Regular updates ensure alignment with evolving technology and security standards.

Developers are going to want to bring their own devices. Forcing them to work on a corporate machine - with all sorts of limitations - will definitely frustrate them. When I was working as an Engineering Manager a couple years back, the biggest frustration of our developers was having to find workaround for the corporate device.

When crafting a BYOD policy, several critical elements must be considered. These elements include: - Security Requirements - Acceptable Use - Privacy Considerations - Support and Maintenance - Compliance and Legal Issues - Reimbursement and Costs - Device and Software Standards - Training and Awareness - Exit Strategy - Regular Reviews and Updates

First issue to address in a BYOD policy is why allow BYOD at all? Is it just a staff perk to have free WiFi/Internet? Is it necessary to do your job? Like, using MyGovID to login to government services? Is it desirable to have staff use the Intranet on their personal devices? Like, for HR matters or for some personal services the organisation offers staff. These concerns inform the rest of the policy, maybe it's not one-size-fits-all BYOD.

A Holistic Approach is needed based on the organization's needs, the various business processes, Complexity of Operations, clearly define the BYOD POLICY, the first thing is to have zero access unless you know devices, military-grade security which is multi-layered, need access policy, Traning, data access and ownership, various layers of cyber security, data auditing, packet level scrutinizing, user training, deployment of various data models, many more need to be part of the policy

The implementation of a virtual desktop infrastructure (VDI) or Windows 365 (W365) can significantly change the dynamics of device management in a BYOD environment. These technologies offer alternative approaches to managing and securing devices and data, which can complement or, in some cases, simplify traditional device management strategies. - Reduced Device Dependency - Enhanced Security - Simplified Management - Access Control - Compliance and Auditing - User Experience - Network Considerations

Requiring device management for BYOD is fraught with pit-falls. Absolutely necessary for corporate devices, but unless you are providing 24/7 support for staff BYOD there are so many risks for staff allowing their personal device to be managed by their employer. Privacy concerns are #1 followed by availability. Can 'monitoring' of the BYOD reveal job applications to a rival company? Work's MDM borks your phone when you need to be on call to pick up the kids, would be a disaster. The BYOD policy has to ensure there is only ever information pertaining to the owner is accessed/stored by the unmanaged BYOD in question. Expect uptake to be negligible if BYOD is treated the same as corporate. Policy specifies need for corporate device instead.

Here’s-measure on the key aspects and techniques involved in effective device management: 1. Device Authentication: 2. Encryption: 3. Remote Wipe, Lock, or Locate: 4. Software Updates 5. VPN 7. Backup Solutions 8. Application Control 9. Feature Restrictions 10. Compliance Checks 11. Geofencing 12. Inventory Management By implementing these device management tools and techniques, organizations can exercise greater control over the security of devices accessing IT services in a BYOD environment. This approach enhances overall security, reduces risks, and ensures compliance with BYOD policies. Regular monitoring and updates to device management strategies are essential to address emerging security challenges.

Device management acts as a reinforcing mechanism for your BYOD policy. It empowers organizations to enforce policy guidelines by restricting or blocking specific applications, features, or functions on connected devices. By integrating these measures, businesses can confidently embrace the flexibility of BYOD without compromising on security.

Zero Trust micro-segmentation will be the right approach here, with the principle of least privilege (Role-based access - RBAC, Attribute-based access - ABAC…). For the remote users, Zero Trust Network Access (ZTNA) based on a comprehensive SASE platform will bring the best outcome.

Network segmentation acts as a strategic barrier, bolstering the defense against potential security breaches in a BYOD environment. This method not only protects critical services but also optimizes network performance by tailoring access rights and bandwidth allocation according to each device's role.

From my perspective I would rate this as the first thing to do before embarking on any BYOD program. The key here is ensuring employees are aware and alert, even on traditional closed networks that have VPN and/or CITRIX based entry to services. Prepping them to be security vigilant ensures that not only in a corporate sense you are protected but in a personal and individual sense. An employee could be compromised at home, on personal email for example, and that _could_ open up vulnerabilities in a corporate setting. Coach and train your employees now, before setting into motion any BYOD plans.

You wouldn't be the first company to have employees that download (or pirate) movies from illegal sources, while being connected to the VPN. As a company you might be liable for any consequences of your employees actions when they are using your network. Education will help everyone in the company what NOT to do when working with company material and networks.

Educating your people about cybersecurity risks is one of the first things organizations should do. The social engineering practice of Pretexting is a form of social engineering that involves creating a false backstory to gain trust. For example, a pretexting attacker might call an employee and claim to be from a customer service department. They might then ask the employee to verify their identity by providing their personal information or resetting their password. BYOD policies can help mitigate the risk of social engineering attacks by implementing strong access controls: Employees should only be able to access corporate data and networks from their devices if they have been appropriately authorized.

Employee education acts as a proactive defense against potential vulnerabilities, transforming employees into informed contributors to overall IT service security. By instilling a sense of responsibility and awareness, organizations can significantly mitigate the human factor in security risks within a BYOD environment.

Regular and thorough monitoring not only allows for timely threat detection and response but also provides invaluable insights for ongoing improvement. This iterative process contributes to the resilience and efficiency of IT services in the dynamic landscape of a BYOD environment.

Technology constantly changes; reviewing the current tech stack to ensure it meets the current security landscape and identifying if your current vendors have added new features that can reduce employee friction are both excellent practices.

Subject to industry, an organisation will typically be running a mix of legacy and /or modern apps (either cloud based SAAS apps or client apps which support modern authentication mechanisms). To support BYOD environment securely: 1. Identify Crown Jewels of the organisation (data, apps) 2. Consolidate and converge application delivery mechanism (ADC) which are entry points into your organisation. Integrate ADC with Modern Authentication Identity plane and apply strict conditional access policies (MFA plus device /browser compliance rules). 3. Work on a roadmap to modernise apps to support modern authentication and adopt strict network segmentation policies to isolate and provide only required access. Implement strict DLP for users.

One method to increase security overall and especially relevant to BYOD is to protect your applications and data rather than your endpoints. Assume your endpoints are compromised. Don't allow unlimited access from clients. Require strong authentication for each request and authorize each request based on this context. This of course requires system modification at many levels but can be part of an overall application modernization program. For more information on this topic research zero trust architecture. This term has been used heavily for marketing particular products but that doesn't make the mindset any less effective.

You can't. Rather than byod, just establish a good set of standard operating environments that cater for different requirements.
