Can i stop apps from downloading cached data

Your Safari cache might be the culprit responsible for your large amount of Other iPhone data. You can either clear your website data with your search history, or clear only your website data retaining your search history in case you need it. Even if you delete both, your AutoFill information will remain. Removing Website Data while keeping history. The easiest way to save space is to consolidate your emails. If this is the case, you can delete one app and use only the other one, potentially halving the amount of storage used!

Another way to cut down on your email data is by removing and then re-adding your email. This can help you to free up storage by clearing this data from your iPhone though not from your email account. Removing and re-adding your email account to save data. Be aware that doing so will also cause your Apple Watch to backup and restore, too. Find out how to create a backup and restore your iPhone here. If you find your iPhone storage is being held at the mercy of your holiday photos, here are some steps you can implement to increase storage on your iPhone by reducing the amount of storage dedicated to Photos:.

Because we store a considerable number of photos on our phones, many of us unknowingly store multiple copies of the same photo on one device, or store multiple versions of similar pictures, where we only need one.

Deleting duplicate photos can free up a significant amount of space. Photos can be deleted manually, one by one, or as a group, but both of these methods are significantly time-consuming. Speed things up by using one of the many free apps available, such as Remo Duplicate Photos Remover , which can not only find and delete duplicates, but also allows you to delete similar photos.

Removing duplicate photos with Remo. Using iCloud, you can optimise photo storage, by moving full-resolution versions of most of your photos to iCloud, with lower-resolution versions still available to browse on your iPhone.

See our iCloud storage guide for more information about iCloud. Once you have enough iCloud storage for your photos, you can move the majority of your photos to iCloud by following these steps:. This space will become available with the images offloaded as you begin downloading films, apps and music. And in the meantime, you can continue to view, share and edit your images in full resolution without waiting for them to download.

There are a couple of drawbacks to this method, however. Another drawback is that your iPhone may not be able to recognize who is in each photo, so your albums of people may not record all the photos you have of each person, although any photos that have already been sorted into these albums will not be removed after they have been offloaded.

This is an easy way to free up some additional space in your Photo Library. When you delete photos on your phone, they move to a folder of recently deleted photos. Your iPhone will permanently delete these photos after 40 days, but in the meantime, those photos are still using up storage on your iPhone. Free up storage by emptying your Deleted Photos folder. To make sure this function is enabled on your iPhone:.

Store images in High Efficiency to save space. We, at TechWelkin and our reader community will try to assist you. Thank you for using TechWelkin! The only ones that can be uninstalled are those that came from Google play store. Like Duo and Knox. Another problem is the memory.

I had to clean it up every time to make space otherwise, it will lag or slow down the speed. And what apps are better kept with battery optimization and wich ones can be deleted. I removed Gboard [I have a different keyboard] google Korean, pinyin can both be removed, Both facebook apps can be removed, prime video can be removed. Thanks man that was a lot of good info, I had no idea what APK was and now with what you have told me I will put it help with my phone, again Thanks.

I have a government free phone Q link.. When I got it 7. GB out of 8 were used. That does nothing to free up space. What do you suggest I do to free up some space so I can view my accounts and put even 2 games on my phone? Love your site, Susanne. Can someone be a bit more specific please? How can I improve the storage on my Android phone? I have Moto E5. Spotify has filed a lawsuit against Apple's app store practices. And then there is the Epic battle with Apple over Fortnite.

If you don't believe me, you should see app owners contacting me to create a PWA for them. Some because their apps were removed. Others because they fear removal or rejection. So does Apple care about AppStore success? Yes, they do, but at the same time it is not their priority, selling hardware at massive margins is the goal. But as I highlighted in the Spotify vs Apple article, much of that revenue is from a handful of apps.

I have created a litmus test to determine if your app should be native or a progressive web app: Does your app sell iPhones? If the answer is no, then don't waste your time and money on a native app. Apple does not want you anyway. I am still here to make it available to everyone for less. When you take the time and create a proper progressive web app you are taking the time to create a better user experience.

This better UX ultimately means your customers are happier with your online experience and of course engage at higher rates. Even with platform limitations a consistent message from brands using PWA is their iOS engagement numbers increase. There are many PWA examples out there reporting across the board improvements to key performance indicators. Even with the current limitations making a better web user experience means you will reap rewards on iOS. And eventually Apple will catch up to the competition.

At least to where Chrome, Edge and other browsers are today. When those missing features light up your customers will just experience them. We know about 4 years ago consumers reached app fatigue and stopped downloading or installing apps. Yes, apps are still downloaded, but for the most part it is the 4 or 5 apps the consumer uses the most and only when they get a new device.

For the most part these apps are Facebook. The other apps are video, which honestly can be progressive web apps without degrading experience. I mean Netflix is phasing their apps out. Most apps are eventually abandoned and after a while purged from the platform due to lack of interest by device owners.

Unfortunately, many still fear or falsely assume they need to have their brand in the AppStore to be found. They are searching for your products and services in search engines. Once you get them on your site you can easily remarket and engage them in your sales funnel. You just need to get them to formally install or add your PWA to their device homescreen.

A far easier task than downloading an app. I frequently read articles about limitations of progressive web apps on iOS. Sure, there are limitations with Apple Safari due to its laggardness in supporting modern web standards.

The current joke among web developers is Safari is the new Internet Explorer. Of course, Internet Explorer is Microsoft's old, long deprecated browser that had so much disdain passed its way. It lagged behind its rivals FireFox and then Chrome. Today most browsers support the same modern web standards and capabilities.

Most except Safari, which always seems to be at least years behind the competition. The story is not as bad as that sounds. The boundaries can be handled if you plan for them. And if and when Apple ships support for a feature it can just light up in your application. I have built applications that deal with iOS limits. Make sure you can detect and respond to a potential alert. In many scenarios, thin client devices are perfect for high-risk environments.

Thin clients run a specialized version of an operating system, only having enough of an operating system and application to connect to a Citrix session. In this scenario, there are benefits around patching. With thin clients there are limited applications to be patched and maintained. Usually the operating systems have reduced footprint. Due to the devices having a simplified and purpose-built operating system, there is limited data at rest on the endpoint. For thin client terminals that run a full operating system, the use of write filters to stop the persistence of data is useful.

Resetting the terminals when a reboot occurs reduces the chance of an attacker persisting data on the endpoint that can be used to formulate an attack. Make sure you are not destroying logs and other critical data, as it is needed for later forensic analysis.

Thin Client terminals have the added benefit of usually being cheaper to purchase and maintain than traditional desktops or laptops. Patch management must be one of the foremost considerations to factor into choosing an endpoint.

How does the business get security fixes applied to the endpoints? These services are great if corporate IT manages the endpoint. What about BYOD? Who patches those devices to ensure they are up to date? With work from home growing rapidly, endpoint patching becomes more complicated. Policies must be defined with clear responsibilities for the user.

The policy is needed to ensure that users know how to patch and update their devices. Simple notifications on the login page suggesting a new update has been released and they need to be patched as soon as possible is one method.

You can also use Endpoint Analysis Scans EPA on the endpoint to deny access to the infrastructure unless they are running up to date software. It is also important to ensure that the Citrix Workspace app is patched and up to date on the endpoint.

Citrix provides not only feature enhancements, but also security fixes in new releases. The end user is widely considered the weakest piece on the attack surface of an organization. It has become common practice for attackers to use sophisticated methods to fool users into installing malware on their endpoints. Once installed, the malware can silently collect and exfiltrate sensitive data. Endpoints become an even more exposed threat surface with the increase in BYO devices.

And when accessing corporate resources from unmanaged endpoints. With many users working from home, the risk to the organizations is heightened due to the untrustworthiness of the endpoint device. With the use of virtual apps and desktops, an attack surface of endpoints has been greatly reduced. Data is stored centrally in a data center and it is much harder for the attacker to steal it. The virtual session is not running on the endpoint and users generally do not have permission to install apps within the virtual session.

The data within the session is secure in the data center or cloud resource location. However, a compromised endpoint can capture session keystrokes and information displayed on the endpoint. Citrix provides administrators the ability prevent these attack vectors, using an add-on feature called App protection. The feature enables CVAD administrators to enforce policies specifically on one or more delivery groups. You can find more information in App protection policies tech brief.

Through the user and device layer, there has been a major focus on device security. Things like User account creation and resource assignment authorization processes need to be centralized and managed efficiently. It can speed up onboarding, but it creates creep in terms of permissions and unauthorized group memberships within the central directory. Ideally, the data owner must authorize any group request before being permitted access.

Decommissioning accounts can be simple if integrated properly with HR systems. Sometimes businesses need to flex resources in and out from third parties. Vendor accounts and extra support for busy periods and when outsourcing business. How do those accounts get decommissioned and ultimately deleted? In the best-case scenario, the business has clearly defined procedures for both onboarding and offboarding any contracting resource. Then it must be deleted when the resource is confirmed as no longer being required.

Ultimately, we do not want contractors to log in months after they have left the business. Within the Citrix design process, the Access layer is where users authenticate. Here the necessary policies are applied, and dynamic contextual based access is evaluated. The access tier is designed with a strong level of security in mind and is critical. In the following section, we aim to cover the main tasks to help better secure your Citrix ADC deployment. There are two common deployment types for Citrix ADCs.

The other way is for load balancing applications to make them more highly available and secure. Following the details contained in this document help lower your risk and exposure for items that the Citrix ADC is interacting with. Strong authentication is recommended for all external connections to any internal system. Unfortunately, there are a great number of user names and passwords out there that are searchable by attackers.

They are from past breaches and leaks, with over This number increases the risks of a breach into your company, as more become available. A user name and password must not be your only defense to your applications. You must not inherently trust people with just two pieces of information that can be easily stolen.

You can find more information in product documentation. It provides a level of security on the ICA stream. The configuration binds a certificate to the Desktop service. It encrypts the ICA stream to the given standard of the certificate bound.

For more information on how to carry out this process, read CTX Ensure you are using all the TLS best practices as they are ever-changing. Choosing between a Wildcard or SAN certificate is another aspect of this process. Wildcards can be cost-effective, but they also can be more complicated. Certificate expirations highly impact deployments with a high number of hosts. However, a SAN certificate can effectively be a restricted wildcard for just 2—5 sites. All with the ability to use more than one TLD in the same certificate.

The purpose is to prevent someone with simple network access from seeing what is being requested by users. Certificates are required for each server along with changing the configuration of each server to use the new encrypted port by default port High-Security Recommendation - For a high-security deployment it is recommended to use non-standard ports for obfuscation. Also ensure that there are firewalls configured between the server roles for the XML traffic to control traffic bidirectionally.

Encryption ensures that neither credentials nor session launch data traverse a network without transport protection. In most deployments, the certificate can be issued from an internal certificate authority.

Ensure the use of strong ciphers and TLS 1. Details for this process are outlined in Microsoft documentation. High-Security Recommendation - In high-security deployments we recommend enabling ICA file signing to ensure the files received by the Citrix Workspace app are trusted.

This process is outlined in StoreFront product documentation. VDA Encryption is typically one of the last items configured to increase the session transport security. High-Security Recommendation - In high-security deployments we recommend enabling VDA encryption to further protect the transport of the Citrix session information.

Using a PowerShell script is the simplest method, and the process is outlined in product documentation. Citrix ADC appliances must be deployed in a secure location with sufficient physical access control to protect them from unauthorized access. This requirement applies to physical models and their COM ports.

Find more information in Citrix ADC product documentation - physical security best practices. Having any default password that is known by the IT community is a huge risk.

There are network scanners that can search for default credentials being used on a given network out there. The effectiveness of these scanners can easily be mitigated or even eliminated by simply changing the default password. All service account passwords must be stored in a secure location like a password manager.

The secure storage of all service account passwords is a foundational information security standard. The password for each role and deployment HA Pair must be unique and credentials must never be reused.

Every device in your network must be denied the ability to manage your Citrix ADC appliances. This configuration ensures that only Authorized Privileged Workstations or other authorized networks can access them for management.

By securing these IPs in a controlled manner you can drastically lower this attack vector or eliminate it altogether. Anytime you limit access of the management of any IT system, you must be document it thoroughly. We do not recommend using generic login accounts for day-to-day administration. When all configuration changes are done by nsroot in an IT team, you will not be able to track who logged in and made a particular change.

Once the nsroot accounts password has been changed, the system should then immediately be bound to LDAPS to track usage to a specific user account. This step provides delegated control so you can create View Only groups for auditing and application teams.

You can then allow full admin rights to specific AD groups. We do not recommend binding using unencrypted LDAP, as credentials can be collected with packet captures. You can find more information in CTX Also, ensure NTLMv2 is the only hashing method for credentials, and network sessions.

This step is an AD security best practice. It ensures that credentials are as protected as possible while in transit for authentication requests and network sessions. Properly test this configuration and validate with older Windows clients - to identify compatibility issues with older versions of Windows.

When binding to any external authentication source, you must disable local authentication for accounts like nsroot. Optionally, only enable specific local accounts to use local authentication. Depending on your deployment requirements can require one path or another. If there is a service account needed, you can create and delegate an LDAP user. This guide covers setting up both methods, one method must be deployed. The practice of Syslog Forwarding is critical for providing incident response along with more advanced troubleshooting.

These logs allow you to see login attempts to the ADC. The Citrix Gateway can take actions which are based on policies from packet and system operations such as:. This information can be invaluable for troubleshooting issues. This detail helps you understand a potential current attack situation.

It will help determine how to best react based on actionable data to resolve issues, stop, or mitigate an attack. Without a Syslog target configured on your Citrix ADC, the required logs are deleted to save space for the system to stay operational. There are many free and paid Syslog servers and collectors available. Some are priced according to the number of messages per day, storage space of messages, or they are just a continuous subscription. These solutions must be planned for, as they require a sizable amount of storage space to be allocated.

Your Syslog server or collector must be sized based on the number of events from other critical services. These services include Active Directory, database, and file servers, VDAs, and other application servers. Citrix ADM can allow you to have some off-device retention. Citrix ADM is also a great tool to be able to search and view these logs and use its events dashboards.

There are many great default views of log data to help you troubleshoot, view hardware, authentication issues, configuration changes, and much more. You can find more information in Citrix ADM product documentation - Configuring syslog on instances and View and Export syslog messages. We highly recommend using this list of messages to create your alerts based on what features of the Citrix ADC you have in use.
