Without mobile device security measures, organizations can be vulnerable to malicious software, data leakage and other mobile threats. Security breaches can cause widespread disruptions in the business, including complicating IT operations and affecting user productivity if systems must shut down.

A lack of mobile security can lead to compromised employee, business or customer data. If an employee leaves a tablet or smartphone in a taxi or at a restaurant, for example, sensitive data, such as customer information or corporate intellectual property, can be put at risk.

Application security is also a mobile security concern. One problem is mobile apps that request too many privileges, which allows them to access various data sources on the device. Leaked corporate contacts, calendar items and even the location of certain executives could put the company at a competitive disadvantage. Another concern is malicious software or Trojan-infected applications that are designed to look like they perform normally, but secretly upload sensitive data to a remote server.

Malware attacks are a common mobile security concern. Experts say Android devices face the biggest threat, but other platforms can attract financially motivated cybercriminals if they adopt near-field communications and other mobile payment technologies.

As is the case with securing desktop PCs or network servers, there is no one single thing that an organization does to ensure mobile device security. Most organizations take a layered approach to security, while also adapting longstanding endpoint security best practices.

Device security. From a device configuration standpoint, many organizations put policies into place requiring devices to be locked with a password or to require biometric authentication. Organizations also use mobile device security software that allows them to deploy matches to devices, audit the OS levels that are used on devices and remote wipe a device. For instance, an organization may want to remotely wipe a phone that an employee accidentally leaves in public.

End-user practices. Some end-user mobile security best practices might include avoiding public Wi-Fi or connecting to corporate resources through a virtual private network (VPN). IT staff can also educate users on mobile threats such as malicious software and seemingly legitimate apps that are designed to steal data.

The most obvious benefit to mobile security is preventing sensitive data from being leaked or stolen. Another important benefit, however, is that by diligently adhering to security best practices, an organization may be able to prevent ransomware attacks that target mobile devices.

One of the biggest challenges to mobile device security is the sheer variety of devices that employees potentially use. There are countless makes and models of smartphones, tablets and other mobile devices. Mobile device management (MDM) software generally supports the more popular devices and the latest mobile OSes, but not all security policy settings work on all devices.

Another challenge to mobile device security is the constantly evolving threat landscape. At one time, there were relatively few mobile threats for organizations to worry about. As devices became more widely adopted, however, cybercriminals began increasingly targeting mobile platforms.

However, organizations typically use other security tools to enhance their mobile device security. This might include VPNs, antimalware software, email security tools that are designed to block phishing attacks and endpoint protection tools that monitor devices for malicious activity.

With the advent of 5G networks in the era of Internet of Things (IoT), wireless and mobile networking have become prevalent everywhere. In this scenario, security and privacy have become the decisive factors. Mobile and wireless ecosystem is an ideal playground for countless perpetrators. (i) Handheld devices are often utilized for critical tasks, such as e-commerce, bank transactions, and application purchases as well as social interactions. (ii) These devices uniquely identify their users and store sensitive and meticulous information about them. (iii) Despite their sophistication, naive security mechanisms have culminated in the bypassing of the mobile operating systems. Moreover, several wireless interfaces and protocols have been found to be vulnerable. As the attacker has a multitude of alternate entry points to perform penetration, the inception of assaults against the user and underlying systems have augmented both in amount and in matters of complexity. It is, therefore, imperative that novel and advanced security and privacy preserving measures be deployed.

However, increases in organizational mobility typically result in an increase in the number of mobile devices that are accessing your systems from a remote location. And for your security teams, this means a growing variety of endpoints and threats they need to secure in order to protect your organization from a data breach.

Mobile security threats are commonly thought of as a single, all-encompassing threat. But the truth is, there are four different types of mobile security threats that organizations need to take steps to protect themselves from:

Mobile carriers are shutting down their 3G networks, which rely on older technology, to make room for more advanced network services, including 5G. As a result, many older cell phones will be unable to make or receive calls and texts, including calls to 911, or use data services. This will affect 3G mobile phones and certain older 4G mobile phones that do not support Voice over LTE (VoLTE or HD Voice).

Some mobile providers have already completed the shutdown of their 3G networks, while others are scheduled to occur later in 2022. Plans and timing to phase out 3G services will vary by company and may change. Consult your mobile provider's website for the most up-to-date information.

If your mobile carrier is not listed here, you may still be affected. Many carriers, such as Cricket, Boost, Straight Talk, and several Lifeline mobile service providers, utilize AT&T's, Verizon's, and T-Mobile's networks. In addition, international visitors to the United States with 3G phones will be affected and are urged to plan accordingly.

As mobile carriers seek to upgrade their networks to use the latest technologies, they periodically shut down older services, such as 3G, to free up spectrum and infrastructure to support new services, such as 5G. Similar transitions have happened before. For example, some mobile carriers shut down their 2G networks when they upgraded their networks to support 4G services. Mobile carriers have the flexibility to choose the types of technologies and services they deploy, including when they decommission older services in favor of newer services to meet consumer demands.

Enhancements in mobile telecommunication networks are galvanizing a wave of digital transformation which is disrupting industries of all types and forcing us to rethink our traditional ways of working. Value chains are becoming value networks, where one-to-one relations between suppliers, vendors, operators, and end users are being reinvented as ecosystems of partners and co-creators.

From a user perspective, 5G is inherently different to any of the previous mobile generations. Machine-type communication, enabled by 5G, is widely anticipated to become the strategic difference and unique selling point of 5G in the long run. 5G networks will serve as critical infrastructures to facilitate the digitization, automation, and connectivity to machines, robots, and transport solutions etc. Thus, there is a significant value at stake and, so too, a significantly different tolerance for risk. 5G marks the beginning of a new era of network security.

Data is one of the most important assets in mobile networks, subscriber data being the most critical one in this category. Subscriber data comprises of communication data (voice, text, and data sessions) as well as subscriber related information, such as identities, location, subscription profile, and connection metadata (e.g. Call Data Records or signaling traces). To protect subscriber privacy, this data needs to be protected at storage and at transport.

Apart from subscriber data, network management related information assets are required for proper operation of the mobile network. The management data comprises of infrastructure and service configuration data, network configuration data, security-related data, monitoring data, such as performance metrics, logs, and traces.

5G will expand traditional relationships between consumers, business users and mobile network operators. The expansion will include new relationships in the form of digitized and automated business processes of enterprises, control, and operations of machinery of industry companies. Furthermore, cyber-physical interdependency between telecom networks and smart connectivity of other infrastructure providers (cities, power, utility, transport etc.) will be enabled by new ways to access the mobile network.

The 5G system may only appear as a faster and more versatile radio technology but it is much more. 5G is the first generation that was designed with virtualization and cloud-based technology in mind. The 5G system is not static for any specific access type or radio technology. For example, new services provided by the 5G core network are also available via 4G radio, Wi-Fi or fixed access depending on the network configuration. Evolution towards the 5G system started in the mid-2000s when the focus in telecom networks was shifted from circuit switched telephony services to packet switched networks and mobile broadband (figure 6). With cloud-based technologies, software execution can now be disconnected from specific physical hardware (removing the need for boxed, e.g. hardware dependent functions). This is made possible thanks to Software Defined Networking (SDN) and Network Function Virtualization (NFV). SDN offers flexibility how to configure the routing paths between dynamically configured virtualized network functions. 041b061a72
