With today’s increasing Mobile Enterprise Security Threats, do you have a strategy to mitigate the risk on your Corporate Network?

/in , , , , , , , , , , , , , , , , , , , , , , , /by

Corporations are increasingly utilizing mobile enterprise systems to meet their business objectives, allowing mobile devices such as smart phones and tablets to access critical applications on their corporate network.  These devices provide advanced technologies over traditional desktop clients, such as: information sharing, access from anywhere at any time, data sensors, location, etc. But what makes these mobile devices desirable, by their very nature, also poses a new set of security challenges.  Reports by research agencies in recent years show an alarming trend in mobile security threats listing as top concerns: Android malware attacks, and for the IOS platform issues with enterprise provisioning abuse and older OS versions.

These trends highlight the need for corporations to start taking seriously a mobile security strategy at the same level to which cyber criminals are planning future attacks. A mobile security strategy might involve adopting certain Mobile Security Guidelines as published by standards organizations (NIST) and Mobile OWASP project. See the references at the end of this document:

The following guidelines are a subset of Mobile Security Guidelines I pulled from various published sources with most coming from NIST. It is by no means a comprehensive list, however they can be considered as a starting point or additional considerations for an existing mobile security strategy.

1 – Understand the Mobile Enterprise Architecture

You should start with understanding and diagramming the flow from mobile application to business applications running on the back-end application server. This is a great starting point and should be done at the beginning stages, as most of the security guidelines will depend on what is known about the architecture.

  1. Is the mobile application a native application or mobile web application? Is it a cross-platform mobile application?
  2. Does the mobile application use middleware to get to the back-end API, or does it connect directly to a back-end Restful based Web Service?
  3. Does the mobile application connect to an API gateway?

2 – Diagram the network topology of how the mobile devices connect

Is the mobile device connecting to the business application servers over the cellular network or internally through a private WiFi network, or both? Does it go through a proxy or firewall? This type of information will aid in developing security requirements; help with establishing a QA security test bed and monitoring capability.

3 – Develop Mobile Application Security Requirements

At a high level, a security function must protect against unauthorized access and in many cases protect privacy and sensitive data. In most cases, building security into mobile applications is not at the top of the mind-set in the software development process. As such, these requirements should be gathered as soon as possible in the Software Development Life Cycle (SDLC). It has been my personal experience in many cases that you have to work with application software developers in adopting best security practices. So the sooner you can get that dialogue going the better. Security objectives to consider are:  Confidentiality, integrity, and availability. Can the mobile OS platform provide the security services required? How sensitive is the data you are trying to protect. Should the data be encrypted in transit, and in storage? Do you need to consider data-in-motion protection technologies?  Should an Identity and Access Management (IDAM) solution be architected as part of the mobile enterprise system? Should it include a Single Sign On functionality (SSO)? Should there be multi-factor authentication, role based or fine-grained access control? Is Federation required? Should the code be obfuscated to prevent reverse engineering?

4 – Incorporate a Mobile Device Security Policy

What types of mobile devices should be allowed to access the organization’s critical assets. Should you allow personal mobile devices, Bring Your Own Devices (BYOD’s) or consider only organization-issued or certified mobile devices to access certain resources? Should you enforce tiers of access? Centralized mobile device management technologies are a growing solution for controlling the use of both organization-issued and BYOD’s by enterprise users. These technologies can remotely wipe the data or lock the password from a mobile device that has been lost or stolen. Should Enterprises consider anti malware software and OS upgrades to become certified mobiles on the network? To reduce high risk mobile devices, consider technologies that can detect and ban mobile devices that are jail broken or rooted, as these can pose the greatest risk of being compromised by hackers.

5 – Application Security Testing

According to a study performed by The Ponemon Institute, nearly 40% of 400 companies surveyed were not scanning their applications for security vulnerabilities, leaving the door wide open for cyber-attacks. This highlights the urgency for security teams to put together some sort of security vetting process to identify security vulnerabilities and validate security requirements as part of an ongoing QA security testing function. Scanning application technologies typically conduct two types of scanning methods: Static Application Security Testing (SAST) which analyzes the source code and Dynamic Application Security Testing (DAST), which sends modified HTTP requests to a running web application to exploit the application vulnerabilities. As the QA scanning process develops, it can be automated and injected into the software build process to detect security issues in the early phases of the SDLC.

6 – System Threat Model, Risk Management Process

What will typically come out of the application scanning process will be a list of security vulnerabilities found as either noise, suspect or definitive.  It will then be up to the security engineers knowing the system architecture and network topology working with the application developer to determine whether the vulnerability results in a valid threat and what risk level based on the impact of a possible security breach. Once the risk for each application is determined, it can be managed through an enterprise risk management system where vulnerabilities are tracked, fixed and the risk brought down to a more tolerable level.

7 – Consider implementing a Centralized Mobile Device Management System

Depending on the Mobile Security Policy that is in place, you may want to consider implementing a Centralized Mobile Device Management System especially when Bring Your Own Device (BYOD) mobiles are in the mix that can:

  • For mobile devices, manage certificates, security setting, profiles, etc through a directory service or administration portal.
  • Policy based management system to enforce security settings, restrictions for organization-issued, BYOD mobile devices.
  • Manage credentials for each mobile device through a Directory Service.
  • Self service automation for BYOD and Reducing overall administrative costs.
  • Control which applications are installed on organization-issued applications and check for suspect applications on BYOD mobile devices.
  • A system that can remotely wipe or lock a stolen or loss phone.
  • A system that can detect Jail-broken or rooted mobile devices.

8 – Security Information and Event Management (SIEM)

Monitor mobile device traffic to back-end business applications. Track mobile devices and critical business applications and correlate with events and log information looking for malicious activity based on threat intelligence. On some platforms it may be possible to integrate with a centralized risk management system to specifically be on alert for suspicious mobile events correlated with applications at higher risk.

Developing an Entitlements Management Approach

/in , , , , , , , , , , , , , , , , /by

We were sitting down with a client during some initial prioritization discussions in an Identity and Access Management (IAM) Roadmap effort, when the talk turned to entitlements and how they were currently being handled.  Like many companies, they did not have a unified approach on how they wanted to manage entitlements in their new world of unified IAM (a.k.a. the end of the 3 year roadmap we were helping to develop).  Their definition of entitlements also varied from person to person, much less how they wanted to define and enforce them.  We decided to take a step back and really dig into entitlements, entitlement enforcement, and some of the other factors that come into play, so we could put together a realistic enterprise entitlement management approach.  We ended up having a really great discussion that touched on many areas within their enterprise.  I wanted to briefly discuss a few of the topics that really seemed to resonate with the audience of stakeholders sitting in that meeting room.

(For the purpose of this discussion, entitlements refer to the privileges, permissions or access rights that a user is given within a particular application or group of applications. These rights are enforced by a set of tools that operate based on the defined policies put in place by the organization.  Got it?)

  • Which Data is the Most Valuable?- There were a lot of dissenting opinions on which pieces of data were the most business critical, which should be most readily available, and which data needed to be protected.   As a company’s data is moved, replicated, aggregated, virtualized and monetized, a good Data Management program is critical to making sure that an organization has handle on the critical data questions:
    • What is my data worth?
    • How much should I spend to protect that data?
    • Who should be able to read/write/update this data?
    • Can I trust the integrity of the data?
  • The Deny Question – For a long time, Least Privilege was the primary model that people used to provide access. It means that an entitlement is specifically granted for access and all other access is denied, thus providing users with exact privilege needed to do their job and nothing more.  All other access is implicitly denied.  New thinking is out there that says that you should minimize complexity and administration by moving to an explicit deny model that says that everyone can see everything unless it is explicitly forbidden.  Granted, this model is mostly being tossed around at Gartner Conferences, but I do think you will see more companies that are willing to loosen their grip on the information that doesn’t need protection, and focus their efforts on those pieces of data that are truly important to their company.
  • Age Old Questions – Fine-Grained vs. Coarse-Grained. Roles vs. Rules. Pirates vs. Ninjas. These are questions that every organization has discussed as they are building their entitlements model.
    • Should the entitlements be internal to the application or externalized for unified administration?
    • Should roles be used to grant access, should we base those decisions on attributes about the users, or should we use some combination?
    • Did he really throw Pirates vs. Ninjas in there to see if we were still paying attention? (Yes.  Yes, I did).

There are no cut and dry answers for these questions, as it truly will vary from application to application and organization to organization.  The important part is to come to a consensus on the approach and then provide the application teams, developers and security staff the tools to manage entitlements going forward.

  • Are We Using The Right Tools? – This discussion always warms my heart, as finding the right technical solution for customers IAM needs is what I do for a living. I have my favorites and would love to share them with you but that is for another time.  As with the other topics, there really isn’t a cookie cutter answer.  The right tool will come down to how you need to use it, what sort of architecture, your selected development platform, and what sort of system performance you require.  Make sure that you aren’t trying to make the decisions you make on the topics above based on your selected tool, but rather choose the tool based on the answers to the important questions above.

Post #1, Virtual Machines != Security Virtual Reality

PathMaker Group is introducing some exciting new technologies to the market that greatly reduce business cost of securing virtual environments and simultaneously increasing system efficiencies, measured in hard-dollar savings. In order to truly embrace the value of these innovative solutions and approaches, one needs to consider some of the obvious and not-so-obvious security issues rooming in virtual space today.

This post is the first of my multi-part series on securing virtual machine environments and I hope that it provides some additional insight into the security issues that I anticipate would concern every business using virtual machines, or considering using it. Read more
