10 Reasons why businesses need mobile device management (MDM)

The content of this post is solely the responsibility of the author.  AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. 

Mobile device management (MDM) refers to a type of software that allows businesses to manage, configure and secure mobile devices used by their employees. Companies use MDM solutions to maintain a secure environment across all the mobile devices they own or have access to, as well as provide features such as remote wipe, password policies, application management and data protection. This helps them ensure security while providing their employees with access to the applications and data they need.

An increasing number of businesses are either accepting that they need MDM or realising that what they have in place is not sufficient. With that in mind, below are ten reasons why MDM is an integral part of doing business in the 21st century.

1. Enhanced security

MDM technology provides an extra layer of security for businesses, protecting them from breaches and data loss. MDM solutions enable secure authentication, access control and encryption for devices, applications and data, which in turn helps to keep sensitive corporate information safe. ESIMs, or embedded SIM cards can enhance the security of mobile devices even further by allowing businesses to remotely manage and secure their devices.

Improved security is one of the most important reasons why businesses need MDM solutions. With an ever-increasing number of cyber threats, it is essential for companies to take steps to keep their data and systems secure. MDM can help with this.

2. Increased productivity

MDM makes it easier for employees to access the applications and data they need, increasing their productivity and efficiency. By providing them with secure access to the resources they need, MDM solutions help remove the frustration of not being able to do their job due to technical issues or security policies.

The ability to securely access corporate resources from anywhere, at any time, helps boost employee productivity and gives them the freedom they need to work more flexibly.

3. Reduced costs

MDM solutions can help reduce costs in several ways. They enable companies to better manage their mobile devices and applications, which ensures that they are up-to-date with the latest security patches and features. This helps reduce maintenance costs associated with managing outdated equipment.

MDM solutions also make it easier for businesses to deploy new applications, as they don’t have to worry about manually configuring each device. This reduces expensive install times and makes it easier for employees to get started quickly.

4. Improved compliance

MDM solutions help businesses comply with industry standards and regulations. They enable companies to configure devices to meet specific security requirements, as well as monitor and manage mobile devices so that they adhere to corporate policies.

By ensuring that all company devices are configured securely, MDM solutions reduce the risk of data breaches and fines associated with non-compliance. What's more, they can help identify areas where businesses need to improve their compliance processes.

5. Easier troubleshooting

MDM solutions can make it easier for IT administrators to troubleshoot issues on mobile devices. As they give IT teams a centralized view of all connected devices, it’s simple for them to identify any problems quickly and take appropriate action.

This ability to easily monitor employee mobile devices also makes it easier for IT teams to provide support and help employees get back to work faster. Not only does this help reduce the time IT teams need to spend troubleshooting, but it also improves employee satisfaction.

6. Improved user experience

MDM solutions can improve the user experience by providing users with fast, secure access to the applications and data they need. This helps reduce frustration and makes it easier for employees to do their job, which in turn boosts productivity.

MDM solutions also make it easy for companies to deploy new apps and updates remotely, meaning that users always have access to the latest software versions. This ensures that all mobile devices are running optimally and delivers a better overall user experience.

7. Device optimization

MDM solutions enable businesses to optimize individual mobile devices for specific tasks. For example, corporate-owned devices can be configured with the exact set of features needed for each employee’s role, improving their efficiency and reducing costs associated with managing unnecessary features.

Furthermore, MDM solutions can also be used to remotely configure devices for different network settings or regions. This allows businesses to easily manage a fleet of mobile devices in different locations, ensuring that each device is optimized for its specific use case.

8. Improved customer service

MDM solutions can help improve customer service by providing employees with secure access to the applications and data they need when interacting with customers. This helps ensure that customer queries are dealt with promptly and accurately, improving overall customer satisfaction.

The ability to remotely monitor mobile devices also makes it easier for IT teams to proactively identify any issues before they become major problems, further enhancing customer service.

9. Increased visibility and control

MDM solutions enable businesses to gain greater visibility over their mobile devices, allowing them to quickly identify which devices are connected, what applications they’re running, and how they’re being used.

This, in turn, gives IT teams greater control over their deployments, ensuring that all company-owned devices are used for appropriate purposes and helping to reduce the risk of data breaches.

10. Reduced costs associated with lost or stolen devices

By using MDM solutions, businesses can remotely lock down or wipe any device that is lost or stolen. This prevents unauthorized access to sensitive business data, reducing the cost of potential data breaches or fines associated with non-compliance.

What's more, MDM solutions can also help businesses save money by allowing them to manage and monitor their mobile devices remotely, reducing the need for costly onsite visits. This helps make sure that all devices are kept up-to-date with the latest software versions, helping to reduce repair costs in the long run.

Conclusion

In summary, MDM solutions provide a range of benefits to businesses. From improved compliance and customer service to increased visibility and reduced costs associated with lost or stolen devices, they are an invaluable tool for any business looking to improve its MDM strategies.

Cyber Attack news headlines trending on Google

CommScope, an American company that is in the business of providing network infrastructure, was reportedly hit by a ransomware attack. Afterward, cybercriminals leaked data of thousands of the company’s employees onto the dark web, including social security numbers and bank account details of employees involved in the R&D of infrastructure products. It is confirmed that unauthorized access occurred on the servers of CommScope on March 27th of this year, and the criminals managed to obtain full names, postal addresses, email addresses, personal numbers, and other sensitive details.

German-based company Rheinmetall has become a victim of a cyber attack recently, and hackers fraudulently accessed data related to industrial customers, largely from the automobile sector. However, the servers related to the military division remained untouched, and thus, a large-scale business embarrassment was averted. Spiegel, the German news website, was the first to report the incident, and more details are awaited.

The third news item concerns a lawsuit related to Facebook owner Meta. According to the latest media update provided by the social media giant, the business has agreed to pay $725 million as it failed to protect the data of its users from the Cambridge Analytica data scandal. Those who had Facebook accounts from May 24th, 2007, to Dec 22nd, 2022, will be eligible to gain some monetary benefits from the settled amount. The company has created a separate page for users to claim the benefit, and you can find more details on the company’s website.

According to preliminary inquiries launched by the Slovenian government, Chinese hacking group Vixen Panda, aka APT15, was reportedly involved in the cyber attack that took place on the Slovenian Foreign Ministry.

The news is out that a ransomware attack launched by the BlackCat/Alphv gang has crippled the entire computer network platform of American software and technology consulting firm NCR. This resulted in the disruption of the Aloha Point of sale platform, causing trouble for customers and business owners involved in digital banking, POS Systems, and payment processing across restaurants, retailers, and healthcare. NCR Corporation has announced that it has taken all necessary measures to contain the malware spread and assured that the incident will never be repeated.

Malware found in James Webb Space Telescope revealed by US President Joe Biden

Cybersecurity analysts from Securonix have discovered a new malware variant hiding in the images produced by the James Webb Space Telescope. The malware is being dubbed as “Go#Webbfuscator” and has the potential to be spread through phishing emails loaded with a malicious deep image file in a Word document, apart from the James Webb Space Telescope generated images.

According to a source, the malware is written in the GOLANG language, which is commonly used by the Mustang Panda hackers’ group to develop malware that can cross platform OS systems such as Windows, Mac, and Linux.

For the past six months, the highly sophisticated telescope has detected many deep field images in the galaxy and was announced by Biden earlier this year. However, security researchers found that the recently released Webb images also contain malware that might be induced by hackers to target larger computer networks and take control of those victimized systems thereafter.

Technically, images embedded with malware are a common web affair these days, and that is what the memes trolling the big celebrities speak about. But using an image sourced from a telescope and made public by the honorable president seems suspicious. However, those tracking cybercrimes say that anything that becomes a craze or a trend on the web becomes an attractive target to cybercriminals who then start exploiting the trend/craze to trap more victims.

Note that the James Webb Space Telescope is a highly sophisticated device used to read and analyze space. It is equipped with high-resolution lenses that allow the viewing of too old, distant, or minute objects and is used in fields such as astronomy and cosmology, such as the detection of new galaxies. The United States National Aeronautics and Space Administration (NASA) is the owner and designer of the space telescope and received great support from the European Space Agency (ESA) and the Canadian Space Agency (CSA).

Cloud forensics – An introduction to investigating security incidents in AWS, Azure and GCP

The content of this post is solely the responsibility of the author.  AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article.

The cloud has revolutionized the way we do business. It has made it possible for us to store and access data from anywhere in the world, and it has also made it possible for us to scale our businesses up or down as needed.

However, the cloud also brings with it new challenges. One of the biggest challenges is just keeping track of all of the data that is stored in the cloud. This can make it difficult to identify and respond to security incidents.

Another challenge is that the cloud is a complex environment. There are many different services and components that can be used in the cloud, and each of these services and components has different types of data stored in different ways. This can make it difficult to identify and respond to security incidents.

Finally, since cloud systems scale up and down much more dynamically than anything we’ve seen in the past, then the data we need to understand the root cause and scope of an incident can disappear in the blink of an eye.

In this blog post, we will discuss the challenges of cloud forensics and incident response, and we will also provide some tips on how to address these challenges.

How to investigate a compromise of a cloud environment

When you are investigating a compromise of a cloud environment, there are a few key steps that you should follow:

1. Identify the scope of the incident: The first step is to identify the scope of the incident. This means determining which resources were affected and how the data was accessed.
2. Collect evidence: The next step is to collect evidence. This includes collecting log files, network traffic, metadata, and configuration files.
3. Analyze the evidence: The next step is to analyze the evidence. This means looking for signs of malicious activity and determining how the data was compromised.
4. Respond to the incident and contain it: The next step is to respond to the incident. This means taking steps to mitigate the damage and prevent future incidents. For example with a compromise of an EC2 system in AWS, that may include turning off the system or updating the firewall to block all network traffic, as well as isolating any associated IAM roles by adding a DenyAll policy. Once the incident is contained, that will give you more time to investigate safely in detail.
5. Document the incident: The final step is to document the incident. This includes creating a report that describes the incident, the steps that were taken to respond to the incident, and the lessons that were learned.

What data can you get access to in the cloud?

Getting access to the data required to perform an investigation to find the root cause is often harder in the cloud than it is on-prem. That’s as you often find yourself at the mercy of the data the cloud providers have decided to let you access. That said, there are a number of different resources that can be used for cloud forensics, including:

• AWS EC2: Data you can get includes snapshots of the volumes and memory dumps of the live systems. You can also get cloudtrail logs associated with the instance.
• AWS EKS: Data you can get includes audit logs and control plane logs in S3. You can also get the docker file system, which is normally a versioned filesystem called overlay2. You can also get the docker logs from containers that have been started and stopped.
• AWS ECS: You can use ecs execute or kubectl exec to grab files from the filesystem and memory.
• AWS Lambda: You can get cloud trail logs and previous versions of lambda.
• Azure Virtual Machines: You can download snapshots of the disks in VHD format.
• Azure Kubernetes Service: You can use “command invoke” to get live data from the system.
• Azure Functions: A number of different logs such as “FunctionAppLogs”.
• Google Compute Engine: You can access snapshots of the disks, downloading them in VMDK format.
• Google Kubernetes Engine: You can use kubectl exec to get data from the system.
• Google Cloud Run: A number of different logs such as the application logs.

Figure 1: The various data sources in AWS

Tips for cloud forensics and incident response

Here are a few tips for cloud forensics and incident response:

• Have a plan: The first step is to have an explicit cloud incident response plan. This means having a process in place for identifying and responding to security incidents in each cloud provider, understanding how your team will get access to the data and take the actions they need.
• Automate ruthlessly: The speed and scale of the cloud means that you don’t have the time to perform steps manually, since the data you need could easily disappear by the time you get round to responding. Use the automation capabilities of the cloud to set up rules ahead of time to execute as many as possible of the steps of your plan without human intervention.
• Train your staff: The next step is to train your staff on how to identify and respond to security incidents, especially around those issues that are highly cloud centric, like understanding how accesses and logging work.
• Use cloud-specific tools: The next step is to use the tools that are purpose built to help you to identify, collect, and analyze evidence produced by cloud providers. Simply repurposing what you use in an on-prem world is likely to fail.

LockBit Ransomware gang focusing on MacOS

For the first time in the history of Apple Inc, a notorious ransomware-spreading gang seems to have shifted its focus to MacOS-loaded laptops. The LockBit Ransomware Group has now developed encryptors targeting Macs, thus extending their crimes from Windows, Linux, and VMware ESXi servers to Apple computers.

According to the analysis of MalwareHunterTeam, the encryption was found on a ZIP file on the database of VirusTotal, which offers cloud-based security services. Interestingly, the archive also contained encryptors for ARM, FreeBSD, MIPS, and SPARC CPUs. Apple Inc seems to be silent on this issue as it must first investigate and then release an assurance-filled statement that their devices are safe from ransomware attacks.

Coming to other news related to the Cupertino company, Chinese web search giant Baidu has threatened to file a lawsuit against the Steve Jobs-founded company over fake copies being circulated on its official app store in the name of the Ernie Bot app.

Technically speaking, Ernie is a mimic of Microsoft’s ChatGPT and is still functioning in beta version. But for the past 16 days, the Apple App Store and Google Play Store have been buzzing with the Ernie smart app, which is a conversational AI-powered bot used to answer anything and everything.

It works like OpenAI’s ChatGPT and is still in the testing phase. But some developers scraped the idea, developed an app with the same name, and released it on the play store, thus violating the intellectual property rights of the internet services-related company.

Issuing a public statement via the Baidu AI WeChat platform, the company warned all its users that any Ernie app available on the app stores respectively until it makes an official announcement. And that’s true!

What if the app is being circulated to spread malware, spyware, or espionage-related tools?

API security: the new security battleground

The content of this post is solely the responsibility of the author.  AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. 

“While defenders pursue the most powerful and advanced solutions they can find, the enemy needs only a single user with a bad password or an unpatched application to derail an entire defensive position.” This quote by Dr. Chase Cunningham from his book, “Cyber Warfare – Truth, Tactics, and Strategies,” seems a fitting way to begin the topic of cybersecurity battlegrounds.

Regardless of the techniques used, going big, expensive, and glossy – while potentially useful – doesn’t replace the need for a well-reasoned approach to securing assets founded on traditional activities and principles. Innumerable assets are housed behind APIs, and the widespread use of APIs means they are high-profile targets. Securing them is of the utmost importance.

Two historical books came to mind for this topic:

• Art of War, by Sun Tzu
• Book of Five Rings, by Miyamoto Musashi

I chose these two due to their applicability to the topic (oddly enough because they are less specific to modern security – something about their antiquity allows for a broader application).

After revisiting the books, I decided to take Musashi’s five (5) principles (scrolls; Earth, Water, Fire, Wind, and Void) and match them as best as possible with 5 of the numerous teachings from Sun Tzu. I then applied them to securing APIs in the growing cybersecurity arena where there are an increasing number of threat actors.

Earth

Musashi’s focus in the Earth Scroll is seeing the bigger picture. Practitioners need to know the landscape or the 30,000 ft view. Sun Tzu said, “The supreme art of war is to subdue the enemy without fighting.”

How to Apply

One needs to understand the nature of API attacks and attackers in securing APIs. One example of a common exploit category is Security Misconfiguration.

Some fundamental API security activities that can prevent attacks before they even get started including following an SDLC, implementing access control, deploying some form of edge protection, using continuous monitoring and alerting, and using appropriate architecture and design patterns.

API attackers are ruthless and relentless. Most criminals want an easy win and using good defense will fend off a high percentage of attacks.

Encryption is a must, both in transit and at rest. The enemy can be thwarted by not being able to use what was stolen.

WATER

It’s important to be experienced and flexible – or fluid – on an individual level, and that includes one’s role in the company. Sun Tzu said, “Be flexible.”

How to Apply

Gathering cyber threat intelligence (CTI) makes it possible to adapt to changing threats in real time. Intelligence gathering, even using Contextual Machine Learning (CML), means that one doesn’t depend on past information, hearsay, rumors, or peer information. Rely on as much clear, relevant, and current information as possible about threats and risks for one’s own company.

In addition to CTI, focus on a well-designed and tested incident response plan.

Intelligence and responding to incidents go a long way toward making company security agile and adaptable.

FIRE

The Fire aspect is about the actual use of the weapons (tools) on the battlefield. Sun Tzu said, “The enlightened ruler lays his plans well ahead; the good general cultivates his resources.”

Now that the proper foundations have been built, it’s time to use the API tools that have been implemented.

How to Apply

Manage and maintain the API resources and identify the strengths and weaknesses of the API system, Ensuring secure authentication and authorization methods for API access.

Also, set fire to vulnerabilities through regular security testing. This should include vulnerability scanning and pentesting, if not red/blue/purple teaming, or even something like Chaos Monkey to test uptime (an oft-overlooked aspect of API security).

Wind

This is also interpreted as “Style.” Here, the goal is to study (not just passively observe) opponents. Sun Tzu said, “If you know the enemy and know yourself, you need not fear the result of a hundred battles.”

How to Apply

For the modern day, we’ll expand this to studying how other companies have dealt with cybercrime and cyberattacks. One will improve by studying others based on facets such as industry, regulations, and org size.

It's easy for a company to a) think it's alone or b) believe it does better than anyone. This can lead to isolation. Org leaders have every reason to set their org apart – distinction is a major component in having a chance at creating a profitable, if not lasting, business. But there aren't all that many ways to uniquely secure a business – phishing is phishing whether against an international enterprise or a local coffee shop; an API for a fintech org is much the same as an API for ice cream shop (the architectures available are only in a few flavors) – many people can use it and abuse it.

Intelligence sharing with other companies can be helpful in creating a secure community.

Void

The idea here – also called Emptiness, is understood as “no mind.” This doesn’t mean that no brain activity is involved, but points more to intuition, awareness, and acting on instinct. Action doesn’t always require thinking things through, getting input from others, and planning something. Some things – whether by natural inclination or by training – are just second nature.

Sun Tzu said, “Utilize your strengths.”

How to Apply

Play to your strengths: individual, departmental, corporate. There’s no one else like you or your company.

Leverage the strengths of your API resources to enhance security. Make sure you know your tools in and out. Often, they’re expensive and very likely, they’re not used to full capacity.

Focus on continuous learning and improvement. This requires a team of individuals who work well together and are independently passionate about defending data.

This intuitiveness is not based on industry, spreadsheets, or data analysis but depends on relevant stakeholders' individual and collective expertise. Often, it will be addressing many fronts at once, such as improved IR, developer training, choosing a platform that provides numerous API protections (while also avoiding a single point of failure), getting legal and compliance teams to determine next steps in the privacy regulation landscape, and performing regular incident response and disaster recovery exercises.

Epilogue

To paraphrase the classic ending of many of Musashi’s teachings, these ideas should be given careful and thorough reflection.

Identity and Access Management (IAM) in Payment Card Industry (PCI) Data Security Standard (DSS) environments.

This is the first of a series of consultant-written blogs around PCI DSS.

Many organizations have multiple IAM schemes that they forget about when it comes to a robust compliance framework such as PCI DSS.

There are, at minimum, two schemes that need to be reviewed, but consider if you have more from this potential, and probably incomplete, list:

• Cloud service master account management AWS (Amazon Web Services), Microsoft Azure, Google Cloud Platform (GCP), Oracle Cloud Architecture (OCA),
• Name Service Registrars (E.g., GoDaddy, Network Solutions)
• DNS service (E.g., Akamai, CloudFront)
• Certificate providers (E.g., Entrust, DigiCert)
• IaaS (Infrastructure as a Service) and SaaS (Software as a Service)) accounts (E.g.: Digital Realty, Equinix, Splunk, USM Anywhere (USMA), Rapid7)
• Servers and networking gear administrative account management (Firewalls, routers, VPN, WAF, load balancer, DDoS prevention, SIEM, database, Wi-Fi)
• Internal user account management, (Active Directory, LDAP or equivalent, and third parties who may act as staff augmentation or maintenance and repair services, API accesses)
• Consumer account management (often self-managed in a separate database using a different set of encryption, tools and privileges or capabilities, from staff logins).
• PCI DSS v4.0 expands the requirement to all system, automated access, credentialed testing, and API interfaces, so those need to be considered too.

Bottom line, in whatever fashion someone or something validates their authorization to use the device, service, or application, that authorization must be mapped to the role and privileges afforded to that actor. The goal being to ensure that each is provisioned with the least-privilege needed to be able to complete its or their intended function(s) and can be held accountable for their actions.

As many of the devices as possible should be integrated into a common schema, since having multiple devices with local only admin accounts is a recipe for disaster.

If privilege escalation is possible from within an already-authenticated account, the mechanism by which that occurs must be thoroughly documented and monitored (logged) too.

PCI DSS Requirement 7 asks the assessor to review the roles and access privileges and groupings that individuals could be assigned to, and that those individuals are specifically authorized to have those access rights and roles. This covers both physical and logical access.

Requirement 9 asks specifically about business-based need and authorization for visitors gaining physical access to any sensitive areas. Frequent visitors such as janitors and HVAC maintenance must be remembered when writing policy and procedures and when conferring access rights for physical access.

Requirement 8 then asks the assessor to put together the roles, privileges, and assignments with actual current staff members, and to validate that the privileges those staff currently have, were authorized, and match the authorized privileges. This is one of the few for-ever requirements of PCI DSS, so if paperwork conferring and authorizing access for any individuals or automation has been lost, it must be re-created to show authorization of the current access rights and privileges.

PCI DSS v4.0 requires much more scrutiny of APIs – which are a growing aspect of application programming. The design engineers need to ensure that APIs and automated processes are given, or acquire, their own specific, unique, authorization credentials, and the interface has session control characteristics that are well-planned, documented, and managed using the same schema created for Requirement 7. Cross-session data pollution and/or capture must be prevented. If the API is distributed as a commercial off-the-shelf (COTS) product, it cannot have default credentials programmed in, but the installation process must ask for, or create and store appropriately, strong credentials for management and use.

Requirements 1 and 6 both impact role and privilege assignments also, where separation of duties between development and production in both networking and code deployment is becoming blurred in today’s DevSecOps and agile world. However, PCI’s standard remains strict and requires such separations, challenging very small operations. The intent is that no one person (or login ID) should have end-to-end control of anything, and no-one should be reviewing or QA’ing and authorizing their own work. This might mean a small organization needs to contract one or more reviewers¹ if there's one person doing development, and the other doing deployment.

Even in larger organizations where developers sometimes need access to live production environments to diagnose specific failures, they must not be using the same login ID as they use for development. Organizations could choose asmith as the developer role and andys as the administrative login ID for the same person, to ensure privilege escalations are deliberately bounded and easily trackable (per requirement 10). Also, no-one should ever be using elevated privileges to perform their day-to-day job; elevations should always be used for point tasks and dropped as soon as they are no longer needed.

Next, third parties allowed into your cardholder data environment (CDE) – for maintenance purposes for instance – must always be specifically authorized to be there (physically or logically) and monitored while they are there. Most SIEM tools these days monitor everything indiscriminately, but PCI also says their access must be cut off as soon as it is no longer needed.

That might mean time-bounding their logical access, and it does mean escorting them while they are present. Staff must also be empowered and encouraged to challenge people with no badge, or no escort, and to escort them out of any sensitive area until their escort can be reunited with them. If your staff has access to customer premises where PCI-sensitive data is present, (either physically or logically) they must conduct themselves in like manner.

PCI DSS v4.0 also adds a requirement that any normally automated process that can be used interactively (e.g. for debugging) must log any of the interactive usage that occurs, with the appropriate individual’s attribution.

Lastly, PCI DSS 4.0 adds credentialed testing using high access privileges for requirement 11 (although not necessarily administrative privilege), which requires those credentials to be designed into the overall requirement 7 schema and subjected to the requirement 8 restrictions and constraints.

¹Reviewers are secure-code reviewers and security-trained functional QA staff.
