Rarely are security controls modified to reflect new technology. Both BYOD rules and corporate policies offer security vulnerabilities in the mobile world.
Below, we'll go over how to handle this threat. With these security suggestions in hand, your business can make sure that your mobile security procedures are current and reliable.
The security guidelines that Computing Services created for mobile devices are described in this paper. This serves to safeguard confidential information, lower the danger of viruses spreading, and lessen other threats.
Describe Mobile Security
To safeguard sensitive information saved and sent on laptops, smartphones, tablets, wearables, and other portable devices, a set of controls called "mobile device security" has been put in place.
The purpose of mobile device security is to restrict access to the corporate network by unauthorized users. This is simply one element of a larger company security strategy.
To safeguard portable devices like laptops, tablets, and Android and iPhone phones, mobile security is a combination of methods, security architecture, and apps.
To protect consumers and companies against data breaches, this sort of security entails measures to improve mobile device cybersecurity. In addition to protecting data stored locally on the device, endpoints connected to other devices and network hardware are also protected by comprehensive mobile device security.
Why Is Mobile Security So Crucial?
The future of computing and communication will be on mobile devices like smartphones, tablets, and laptops with desktop computer capability.
Because of their size, operating system, applications, and processing capacity, they are perfect for usage anywhere with an internet connection. Every piece of equipment that is augmented with this software and capabilities will transform into a mobile computing system with the arrival of ruggedized devices and the Internet of Things, operating systems like Chrome OS and Windows 10, and the Internet of Things.
Because they are more portable and less expensive than desktop computers, mobile devices are preferred by businesses and users. Due to the extensive usage of wireless Internet, data breaches and attacks are more likely to occur on mobile devices.
Although handy, authentication across mobile devices raises risk since it does away with the limitations of a secure organizational boundary.
Smartphone capabilities are improved by features like multi-touch screens, GPS, microphones, and multi-megapixel cameras, for instance. They also make it possible for them to connect to more gadgets. These new features change how users authenticate and how devices, applications, and services are granted permissions.
The number of devices that need to be protected from cybersecurity threats also rises as a result of the increased capabilities.
As more people travel and work from home, mobile devices are becoming more and more ingrained in the daily life of corporate employees.
Laptops were formerly solely available to traveling personnel, and desktop computers were the only devices that could be used to browse the Internet. The most popular way to browse the Internet is now on a mobile device. The majority of traffic no longer originates from desktops.
Attacks on mobile devices are more likely than those on PCs. They provide a more significant risk to the safety of business networks.
Compared to desktop computers, mobile devices are more susceptible to physical and virtual threats. Users carry their mobile devices with them wherever they go; therefore, administrators want to be increasingly concerned about both physical risks (like theft and loss) and virtual ones (such as man-in-the-middle attacks from WiFi hotspots and third-party apps).
Because fixed computers are not disconnected from the business network, network administrators and security may be managed more easily. Mobile devices can be physically lost by users, and they can also be rooted.
Many of these problems, along with others, make it more difficult for businesses to design plans for mobile devices.
Mobile devices, despite the increased workload, are an essential component of cybersecurity since they represent severe risks to data security.
How to Manage Mobile Device Security in the Enterprise
Aware of the right way to do things and how to use specific resources, this policy has been established. The right to make adjustments is reserved by Computing Services.
Any updates to this policy will be announced by an official. Computing news and mirroring on this website. New opportunities and difficulties are presented by current trends in mobile security.
Personal computing device security needs to be redefined to address this. For instance, a device's capabilities and expectations vary according to the device's form factor, size, and shape, as well as on security technology advancements, changing threats, and device interactions, including audio, video, touch, and other features.
Three key security goals must be met by mobile devices, according to the report:
Confidentiality - Make sure no undesired parties can access any data that is transmitted or stored.
Both trade secrets and personal information are protected.
Integrity- Businesses need to be able to verify that the data they are storing or transmitting is uncorrupted.
Availability- Devices must be functional and secure. Still, they must also enable users to access corporate resources securely from any location at any time.
The following mobile device cybersecurity practices should be used by your business to further your mobile security to accomplish these objectives.
These consist of:

Install A Security Policy For Mobile Devices
You may aid your staff in understanding how mobile technology impacts your organization by developing and describing a mobile device policy in clear terms.
You will also be able to recognize any potential dangers that mobile gadgets can present. This policy should be as similar as possible to your current security measures for non-mobile systems. You'll need to define and further explain the following subjects:
- What assets can be accessed by mobile devices?
- What devices work with those resources?
- How much Internet access do mobile devices have, particularly when contrasting personally owned devices with those provided by employers?
- How to handle your company's centralized management servers for mobile devices.
Create Threat Models For Mobile Device Systems
On the other hand, because they are stationary, used at a workplace, and protected by numerous layers of IT security protocols, non-mobile devices are far less prone to breaches.
Because they can be transported outside of the office, thanks to their portability, mobile devices are more susceptible to assault. These devices are accessible to some attacks once they are unexpectedly released from your company's security constraints, including:
- Public WiFi WiFi that isn't secure
- third-party programs
- Viruses and spyware
By creating a system that makes use of threat models, you may estimate the likelihood of an attack. The potential effects of a successful attack.
What security measures need to be strengthened or implemented to fill such gaps?
Include the required security services – To make sure that mobile devices have overlapping coverage, several services are available.
It contains a comprehensive mobile security policy with the following new additions:
Access Limitations for Hardware and Software
Automatic policy violations are found and reported. Management of wireless network interface By encrypting the data and erasing it, you can safeguard its transmission and storage.
This is crucial in cases where a device has been stolen, misplaced, or compromised. Restricted access to mobile app management shops and apps.
Requiring device verification or two-factor authentication to log in, change passwords, install new apps, or have the device automatically lock.
Make Sure That All Company-Issued Mobile Devices Are Secure
Employees and human mistakes pose a severe threat to business security. Industry research claims that employee irresponsibility is the main reason for data breaches.
Forty-seven percent of CEOs surveyed in the study claimed that human error—such as an employee accidentally misplacing a gadget or document—was to blame for a data breach at their organization. Before introducing a device to your employees, it is crucial to take the appropriate safety measures.
Mobile Devices Pose High-Level Risks and Vulnerabilities
Security threats from mobile devices are more complicated than those from static equipment. Due to their inherent susceptibility, mobile devices frequently require additional protection, according to the report.
Organizations should develop system threat models that take into account mobile devices and the resources they access. Phishing and malware are the leading causes of mobile security issues in this situation.
Protect Your Mobile Device With A Password
Mobile gadgets have a minimal level of physical security, are compact, and are simple to lose. If your mobile device has been lost or stolen, a device password can be the only thing preventing someone from seeing your emails and other critical information.
- Pick a secure password. The security of your system depends entirely on the password you use to secure it. You can find ISO guidelines to assist you in selecting a secure password.
- Complex passwords could be challenging to enter on some devices' tiny keypads. However, you ought to pick a strong password that is difficult to decipher. Consult the document Managing Mobile Security Password for advice on selecting the optimal password.
Disable Applications And Options That You Do Not Use
Use only the most necessary apps and services on your device. By avoiding upgrading applications that you do not use, updates may be managed more efficiently, and battery life can be increased.
If they are not appropriately configured, services like Bluetooth and IR can let unwanted visitors into your device.
Report A Stolen Or Lost Device Immediately
To prevent email or sensitive data from being exposed, a device may occasionally be remotely deactivated using services like the mobile ActiveSync service.
Recognize your alternatives and take advantage of them as soon as you can. Think about writing down or etching your device's serial number.
Make Regular Data Backups
You ought to keep a backup copy in case your gadget is broken or misplaced. Think about various backup options, and if you're traveling, pack a portable device.
Maintain Safe Disposal Procedures
Before disposal, erase all sensitive data from your device. Remote device clearing is possible with several providers, including the Computing provider's Services.
Obtain An Operating System Update
By accepting updates and patches for the operating system of your mobile device, you can lower security threats.
To achieve this, either enable automatic updates or receive updates from the operating system, service provider, or application provider for your device.
Avoid Breaking
Your mobile device is more susceptible to attack or is more likely to attack other systems if you change the factory security settings.
Before Downloading, Check The Programmes
Some applications can damage your smartphone. They could drive you to a malicious website that gathers personal data about you, including credit card details, or they might include malware themselves.
Credit card details). It would help if you searched for the program you want to download to find out about its validity and user reviews—only download programs from reputable sources.
Controls For Physical Security
Anywhere the user goes, they can bring their mobile devices with them. It comprises their residences and shops, as well as establishments like cafes, offices, and hotels.
The likelihood of these gadgets being stolen, lost, or having their data compromised is higher. When creating your device security rules, you should consider the possibility that one or more devices will eventually be obtained or accessed by evil individuals, either physically or online.
Your company should implement the following measures to lessen this:
- Authentication- Before using any device to access organization resources, employees must verify their identification. Typically, a password or PIN is used for this. By requiring all or part of the following, you can progress further.
- Encrypting Data – Encryption is used to safeguard private information about a corporation to prevent unauthorized parties from reading it.
- Employee Education and Training- Your company will be safer if you inform and train your employee on the threats and the best practices, as employee misuse of technology is the primary source of cybersecurity breaches.
BYOD
Due to a lack of security and control, mobile devices owned by individuals are more susceptible to outside threats.
The study notes that:
In communications systems, wireless technologies like WiFi and cellular networks can be used. Sensitive data is in danger since these systems are susceptible to eavesdropping.
Communications can also be intercepted and changed by a man-in-the-middle attack. Using mobile asset management tools, you can keep track of all of your mobile assets.
If you permit BYOD, you should anticipate that the networks connecting individual mobile devices to your company will be insecure. You can solve this problem by doing what is listed below:
- Do not accept BYOD rules.
- Impose a VPN requirement on employees who use their own devices.
- Any network interfaces that do not need to be accessed from personal devices should be disabled.
- Preventing access to personal devices on unsecured WiFi networks
Untrusted Applications
Third-party application stores can easily be integrated into mobile devices. Since app stores don't impose any additional security controls or limits on third-party applications, this security risk is quite severe.
It is preferable to presume that all foreign apps are fraudulent. The steps below can help you avoid harmful apps:
- App installation is not allowed.
- A company's approved apps are the only ones that can be downloaded.
- To keep your organization's data safe from unauthorized access, use a sandbox.
- Verify that only necessary permissions are granted to applications.
Web-based apps that can be accessed using mobile browsers are NOT addressed by these mitigation measures. It might be worthwhile to limit browser access to these applications and take the following actions:
- Servers that act as HTTP proxies are an excellent approach to secure your web traffic.
- Using secure gateways to send device traffic.
- Use a secure sandbox with a browser.
Location Services
Nearly all mobile devices offer location services. Using the GPS position, the online browser, apps, navigation, and social media are all optimized.
The likelihood of a device assault rises as a result. Hackers now have access to real-time information on the whereabouts of the user, the device, and their activities. To solve this issue, think about taking the following actions:
- It's against the law to use location services in the photo and social networking apps.
- Employees should manually turn off the location service when they are in sensitive areas.

Incorporating Guidance
It is advised that you put an action plan into place based on its five-phase life cycle model to apply the concepts outlined above appropriately and to serve as guidance.
Phases include:
Phase 1: Initialization
Before putting a mobile solution in place, your company should first gain a thorough understanding of these variables.
You can also take your company's future security needs into account. Your mobile device requires security, functionality, and performance. You want specific mobile device safety provisions to be included in the policy.
What resources are mobile devices accessible or not? Different levels of access are available on mobile devices. This will rely on a variety of elements, such as:
- Sensitivity at Work Cost
- Place of Employment
- technical restrictions
- Confidence in policy compliance
- Other policies to be followed
Phase 2: Development
You can focus on the technical aspects of your policy for mobile device security with the help of your IT department.
It's critical to note the following:
- The kinds of portable electronics that are usable.
- Authentication-based data protection techniques.
- Cryptographic mechanisms can be used to provide extra security levels.
- Particular components handle particular weaknesses.
Phase 3. Implementation
Once you get to this point, the extra security measures and tools are set up, checked, and turned on when the go-ahead is given.
To accomplish this, new security protocols must be included in already-in-use technology and protocols. An evaluation is necessary for the following:
- Apps
- Authentication
- Connectivity
- Standard settings
- Logging
- Management
- Protection
- Implementation security
Phase 4 - Operations and Upkeep
To ensure mobile device security, operational procedures must be carried out regularly. Regular supervision is necessary for these procedures.
- Take private information off of mobile devices.
- Removing or rescinding authorization for dangerous apps.
- The risks and safe use of mobile devices should be made clear to employees.
- Red flag anomalies could be a sign of unethical activity or careless security protocols.
- Keeping an updated list of mobile users and devices.
Phase 5 - Disposal
The Guidelines state that before a mobile component is reassigned or permanently leaves an organization (such as when the lease on a server expires or an old mobile device is recycled), all sensitive data must be removed.
This may take some time, mainly if your security personnel are meticulous.
Components Of Mobile Device Security
You can keep your mobile device more secure by using these options.
Endpoint Security
Organizations must put in place networks that allow remote access to accommodate flexible and mobile staff. By keeping an eye on the data and operations of each mobile device accessing a network, endpoint security safeguards businesses.
Endpoint security can detect attacks sooner by continuously monitoring for unwanted activity. When they identify malicious behavior, endpoint solutions quickly notify security personnel. As a result, threats can be eliminated before they have a chance to cause harm.
VPN
Virtual private networks, or VPNs, are secure connections made between a device and a network over the Internet.
Sensitive data can be safely exchanged thanks to this encrypted connection. This makes it impossible for unauthorized parties to listen in on traffic and enables users to work remotely in safety.
Web Secure Gateway
Secure online gateways have the potential to offer cloud security, which is a potent instrument. Businesses require cloud security because 70% of all assaults are specific to their organization.
They must therefore locate previously launched strikes. By acting at the DNS layer and IP layer, cloud security can defend against malware, ransomware, phishing, and other threats earlier.
By incorporating security into the cloud, you can recognize and stop an attack at a single branch.
Email Security
Email is the primary assault method and the most crucial commercial communication medium. Email is the primary method used by attackers to transmit malware and ransomware, according to the study.
To prevent data loss and secure sensitive information while it is in transit utilizing end-to-end encrypted communications, email security should include advanced threat prevention. This protection should be able to detect, block, and remediate threats more quickly.
Broker for Cloud Access Security
Your network, as well as where and how people work, must be protected. The cloud is a part of this. A cloud access security broker (CASB) is a device that connects your on-premises network to cloud services like Dropbox, Salesforce, and other services.
Using a cloud data protection (DLP) engine, it detects dangerous applications in the cloud and shields users against intrusions.
