Why is remote access important?
Remote access security is crucial for businesses that have a remote workforce, as these employees need to safely access corporate networks from multiple places. As many remote employees work from home, an unsecured network could lead to massive data breaches on both personal and company servers. If your business shares sensitive data to clients via a corporate network, the proper security precautions need to be implemented to protect both parties from malicious code.
What is secure remote access?
Secure remote access represents any security policy, program, or strategy that safeguards a specific application or network from unauthorized access. Rather than utilizing one cybersecurity strategy, secure remote access incorporates multiple security solutions to ensure your business’s confidential information is protected, no matter where your network is being utilized.
How to secure your cloud?
This includes identifying which applications you are currently using, as well those you plan to integrate into your network in the future. Once identified, it’s important to assess these services for any potential cybersecurity risks or vulnerabilities so you can get started implementing the right security measures. Some of the most common cloud app security strategies include:
Why is it important to adjust user permissions?
Adjusting user permissions within your cloud apps allows you to assign or prevent access to sensitive data. Similarly, it’s important to regulate what devices can securely access your cloud network. Many cloud-based services allow you to restrict certain devices from designated applications.
What is zero trust network access?
Zero-trust network access (ZTNA) is a security solution that provides secure remote access to private applications and services based on defined access control parameters. This means that employees only have access to services that have been specifically granted to them. A zero-trust security framework also prevents users from being placed on your network and your apps or services from being exposed to the internet.

What is Citrix best practices?
Citrix best practices for mobile app security are based on containerization, a form of segmentation at the device level. Users can use a single device with both personal and business apps, with business apps and data managed by IT. The security of the hardware, operating system and individual apps is extended by container-based security measures including encrypted storage and usage, app-to-app data control and data wipe policies.
How does application virtualization protect data?
Application virtualization protects sensitive data by centralizing apps in the datacenter and allowing only a pixelated representation of the application to reach the endpoint—no actual data transfer occurs. Virtualization also allows the classification of applications based on their security requirements; sensitive apps can be siloed onto dedicated servers within a separate network segment with different sensitivity classifications and restrictions, and multiple isolated versions of web browsers can be published to address diverse security and legacy requirements of web apps. IT gains a single point of visibility and control to define and enforce access policies on a group or user level.
How does log management help in detecting a threat?
Regular auditing and accounting of user access, configuration changes and account management logs aid threat detection by capturing early indicators of attack and compromise. These can include unusual and large volume of outbound traffic, unusual account activity —especially for privileged accounts—and failed and successful logins from unusual locations. This data also helps IT clean up inactive accounts as best practices recommend. As successful intruders often clean up logs to delay detection of their breach, log files should be stored externally to the system.
How does NetScaler work?
Visibility challenges grow as the number and complexity of applications and deployments increase across lines of business, as well as the tools and techniques used for monitoring. NetScaler simplifies monitoring by providing a central point through which all application information travels. While the primary purpose of this design is to allow load balancing and SSL offload for scalability and availability, it also ideally positions NetScaler to parse both web and ICA traffic for any type of application using any type of encryption. Performance data for this traffic is then sent to NetScaler Insight Center, which uses AppFlow to define and extract visibility information.
What is segmentation in security?
Segmentation extends the rule of least privilege to the network and hosts by defining security zones that minimize unwanted access to sensitive applications and data. Firewalls and gateways restrict traffic to their respective zones, reducing lateral movement and attack surface to contain the blast radius of a breach.
Is NetScaler app firewall a threat?
Such threats are often devised specifically for the target, making identification by network-layer security devices such as intrusion protection systems and network firewalls impossible. This leaves web apps exposed to application-layer attacks using known and zero-day exploits. NetScaler AppFirewall closes this gap by delivering centralized, application-layer security for web apps and services.

Why should Citrix be managed?
Functionality, such as client drive mapping and special folder redirection, should be managed carefully to avoid remote users from unknowingly pulling massive data sets from Citrix clients to Citrix servers for processing. This also prevents problems with authored map documents containing unusable data references, such as \c$.
What is Citrix XenApp?
Citrix XenApp provides two methods for delivering applications : session virtualization (also known as hosted shared sessions), and application virtualization (also known as application streaming). Session virtualization represents the traditional method where a remote session is established and the application is executed remotely from a server. In this configuration, the application is installed onto the server in a similar manner as with a typical desktop. Application virtualization focuses on virtualizing the application itself. The application is 'sequenced' into a containerized format that prepares it for streaming to the client. The application, along with supporting registry information and other components, is essentially wrapped into a customized file structure and served from a file server on demand. The application can be accessed by a XenApp server for delivery via a remote session or directly from a desktop client.
Does XenApp support 3D?
One of the original goals of thin computing was to minimize the impact to the network. To achieve this goal, graphic-intensive and 3D displays were not considered practical in terms of application delivery via XenApp. This has traditionally limited the use of 3D applications within a XenApp environment. However, 3D support has evolved and current XenApp editions (XenApp 6.5 with the OpenGL GPU Sharing Feature Add-on or newer versions) now support server-side GPU acceleration, including support for OpenGL applications (classic Esri 3D applications are OpenGL based). It has been shown that GPUs cannot be used to accelerate ArcMap’s GDI-based display, therefore no advantage is gained by deploying GPUs in XenApp servers for ArcGIS Desktop. For applications such as ArcGlobe, ArcScene, and ArcGIS Explorer, GPUs can be leveraged to accelerate display performance. Network traffic must be considered, as well, since it increases significantly with these types of displays. Therefore, it is recommended that these applications be tested to ensure expected performance objectives can be achieved.
Is XenApp a challenge?
Historically, virtualizing XenApp with ArcGIS proved to be challenging with many deployments. However, as server and virtualization technologies have evolved, the risk associated with virtualizing XenApp servers with ArcGIS has significantly decreased.
Is ArcGIS Desktop blocked?
Since ArcGIS Desktop is running on a XenApp server in the data center, network access is often more secure, and port 80 may be blocked outbound to the internet. Port 80 is required for ArcGIS Online access and other web services, so it is important to ensure port 80 is not blocked for XenApp servers.
Does Citrix XenApp use ArcGIS?
A typical Citrix XenApp deployment with ArcGIS leverages roaming profiles, allowing for a similar user experience regardless of which server the user is assigned. Esri does not require anything beyond the standard best practices published by Microsoft and Citrix for managing profiles. However, there are cases where some changes in profile management are desired. The following cases are examples of profile-related modifications.
Does ArcMap run on Citrix?
To date, there has not been a known configuration where a given version of ArcMap does not run on a given version of Citrix XenApp. However, to increase confidence with the use of XenApp, for several years now Esri has been certifying ArcGIS with XenApp.
