Bridging the gap between DevOps and Security

Security should be baked into the DevOps process, from tools to skills to collaboration. DevOps and security are not mutually exclusive.

The problem with digital innovation is that considerations for compliance come later, after the product or service is on the market. From public cloud infrastructure to Internet of Things to mobile apps and even to DevOps, tough requirements like security aren’t built into innovators’ plans. Entrepreneurs are thinking primarily about shiny, new, fast and disruptive. Yet for the CIO and other chief executives accountable to customers, laws and financial markets, managing risk around sensitive data is top priority.

DevOps processes are at the heart of business innovation: think Netflix, Facebook, Etsy and Nordstrom, all leaders in their sectors. Yet many of the popular DevOps tools and methodologies, whether commercial or open source, haven’t been optimized for the needs of enterprise security. An application running in a container, for instance, will still require attention around configuration to ensure application security.

As well, many security professionals haven’t yet made the leap to understanding the changing best practices for security in this new world of cloud/agile/mobile IT. Some security experts have imposed barriers to DevOps, by resisting the switch to faster, more iterative development along with the public cloud.

On the surface, the speed at which DevOps teams are approving and releasing code would suggest an increase in security risks to end users by eliminating rigorous security review phases. Yet managing security, as with ing, is in fact optimal when performed side-by-side with developers as code is being written. By integrating security, people and processes tightly within the continuous delivery cycle, DevOps can do a better job of eliminating loopholes and gaps in the code before production. DevOps tools emphasize the use of frequent and automated processes to improve software quality: also an ideal model for handling security ing and fixes. Determining the best way to merge security with DevOps is a work in progress. The following concepts can provide a framework for getting started:

  1. Use the best of DevOps for security: DevOps, with its focus on automation and continuous integration, provides a more holistic framework for security management. Start by considering security through every step of the development and production cycle. Security professionals can help developers root out design problems in the beginning – such as ensuring all data transport is encrypted. Integrate automated security checks into development, ing and deployment phases, and educate all team members about the importance of incorporating security thinking in their specific job roles. Security should no longer be the last process before committing the code to production.
  2. Investigate new DevOps and Cloud security tools: Fortunately, the security technology industry is ramping up quickly to the needs of DevOps security. Static Application Security (SAS) tools for security when code is being written while Dynamic Application Security (DAS) tools for interface risks. A few of the reputable systems include Checkmarx, Veracode and Parasoft. The third area of security automation tools covers penetration vulnerability ing, such as Nessus, developed by Tenable. Other contenders in this area include Qualys and OpenVAS. These tools can integrate smoothly into the software development lifecycle, such as by plugging into Jenkins. By adding automation, security is not only built-in, but doesn’t slow down the DevOps process.
  3. Getting buy-in from security teams: This might just be the hardest part. While developers are incentivized to go faster and do more, security professionals are incentivized to control, monitor and reduce risk. Meeting in the middle is definitely possible – but it will require some opinion shifting on both sides. Developers and product managers will need to understand the importance of working collaboratively with the security team, and in an accountable way. Security people can benefit from a more comprehensive understanding of security in the cloud. This should include continuous education on the new tools and services available today to manage risk and to deliver even higher levels of security than in the past – from better reporting, to API-based security and easier encryption at rest.\
  1. Manage tool sprawl: The concept of self-organization is an important one in DevOps, because it fosters a spirit of flexibility and rapid collaboration. Yet this same principle can also lead to environments of dozens or even hundreds of different tools in use to manage deployment, configuration, QA and orchestration. That creates risks for visibility and monitoring as well as standardizing around security controls and access. Engineering leads should help strike a balance between too much and too little governance when it comes to tools and workflows by providing guidelines for tool selection. The DevOps automation infrastructure itself can introduce risks. If a hacker gains access to a tool like Puppet or Chef, he can modify any number of configurations and add new user accounts. Configuration and change management tools must be adequately secured and governed, lest they become a new attack plane.\

With the advent of DevOps, there’s an opportunity at last for security to become an integral and seamless aspect of innovation. We think it’s not only possible but critical to give security the attention it demands in the world of fast IT.

What’s the Plan? A How-To Guide for Preparing Your Cyber Incident Response Program

Last week, we kicked off a four-part blog series with our strategic partner, Alert Logic, that has a focus on the importance of cloud security for Digital Businesses.  This week, Alert Logic has contributed the following blog post as a guide to help digital businesses prepare for—and respond to—cyber incidents.

Evaluating your organization’s cyber security incident response readiness is an important part of your overall security program. But responding to a cyber security incident effectively and efficiently can be a tremendous challenge for most. In most cases, the struggle to keep up during an incident is due to either of the following:

  • The cyber incident response plan has been “shelf-ware” for too long
  • The plan hasn’t been practiced by the incident response team.

Unfortunately, most organizations view cyber incident response as a technical issue—they assume that if a cyber incident response plan is in place and has been reviewed by the “techies,” then the plan is complete. In reality, all these organizations have is a theoretical cyber incident response plan, one with no ing or validation. Cyber incident response plans are much more than a technical issue. In the end, they are about people, process, communication, and even brand protection.

How to ensure your cyber incident response plan works

The key to ensuring your cyber incident response plan works is to practice your plan. You must dedicate time and resources to properly the plan. Cyber incident response is a “use or lose” skill that requires practice. It’s similar to an athlete mastering a specific skill; the athlete must complete numerous repetitions to develop muscle memory to enhance performance. In the same way, the practice (repetitions) of ing your cyber incident response plan will enhance our team’s performance during a real incident.

Steps for ing your plan effectively

 Step 1: Self-Assessment and Basic Walk-Through

An effective methodology to your cyber incident response plan begins with a self-assessment and simple walk-through of the plan with limited team members.  Steps should include:

  1. The incident response manager reads through the plan, using the details of a recent data breach to follow the plan. The manager also identifies how the incident was discovered as well as notification processes.
  2. The team follows the triage, containment, eradication, and forensics stages of the plan, identifying any gaps.
  3. The incident response manager walks through the communications process along the way, including recovery and steady-state operations.
  4. The team documents possible modifications, follow-up questions, and clarifications that should be added to the plan.

Step 2: All Hands Walk-Through

The next step to a self-assessment is the walk-through with the entire incident response team. This requires an organized meeting in a conference room and can take between 2-4 hours, in which a scenario (recent breach) is used to walk through the incident response document. These working sessions are ideal to fill in the gaps and clarify expectations for things like detection, analysis, required tools, and resources.  Organizations with successful incident response plans will also include their executive teams during this type of .  The executive team participation highlights priorities from a business and resource perspective and is less focused on the technical aspects of the incident.

Step 3: Live Exercise

The most important step in evaluating your incident response plan is to conduct a live exercise.  A live exercise is a customized training event for the purpose of sharpening your incident response teams’ skills in a safe, non-production environment. It isn’t a penetration ; it’s an incident response exercise designed to your team’s ability to adapt and execute the plan during a live cyber attack.  It’s essentially the equivalent to a pre-season game—the team participates, but it doesn’t count in the win/loss column.  The value of a live exercise is the plan evaluation and team experience. The lessons learned usually prove to be the most valuable to the maturation of your cyber incident response plan.

Ultimately, preparedness is not just about having an incident response plan; it’s about knowing the plan, practicing the plan, and understanding it’s a work in progress. The development of an excellent incident response plan includes involvement and validation from the incident response team as well as a commitment to a repetitive cycle of practice and refinement.

5 Tips for Getting Started with Cloud Security

Implementing security in a cloud environment may seem like a difficult task and slows down, or even prevents, some organizations from migrating to the cloud.  Some cloud security models have similarities to traditional data center or on-premises security; however, there are opportunities to implement new security measures as well as tweak your existing security plan. Here are five tips for getting started with cloud security.

  1. Secure your application security code
    Knowing and understanding account usage and the types of coding languages, inputs, outputs, and resource requests is essential.
  2. Implement a solid patch management and configuration management strategy
    These strategies are usually more people and process driven, but are important components to the care of feeding of the technology solution.  Organizations should take inventory of all the data they are maintaining and understand what type of data it is, where it is being stored, what accounts have access to this data, and how is it being secured.
  3. Dedicate time and resources to the design and maintenance of identity and access management solutions
    Attackers continue to use brute force attacks against accounts to crack passwords and gain authenticated privileges in your environment.  Accounts should follow the least privilege concept and account activity should be logged.  A robust logging and log review system should be a standard implementation for all systems, accounts, and configuration modifications to ensure accountability of legitimate activity.
  4. Understand the shared responsibility of security
    Generally, cloud providers will have security implemented throughout their core infrastructure, which is primarily designed to safeguard their systems and the basic foundational services for each of their customers.  Cloud providers will maintain and secure their infrastructure; however, they won’t necessarily provide customers reports or notifications from this layer unless it impacts a significant amount of customers.  Therefore, it is highly recommended that you implement a customized security plan within your own cloud environment.

    At the moment a cloud provider drops a network packet onto your systems, you should employ security monitoring and network threat detection.  The customer responsibility for security increases when moving from the network level to the host level and further to the application level.  Once you have access to your operating system, you are giving root/administrator access and therefore, that system is yours to secure and manage.

    At this point, the customer is responsible for the security of the applications and the application code that is used on the host systems. Cloud customers need to pay particular attention to the application code that is used in their environment since web application attacks are the most prevalent type of attacks used by adversaries.

  5. Stay informed about the la threats and vulnerabilities
    Organizations should also stay informed about the la threats and vulnerabilities to their cloud systems.  Adversaries, hacking groups and security researchers are constantly working to discover new vulnerabilities within systems and keeping up with these threats is imperative.  Organizations that have dedicated resources to monitoring and responding to the la threat activities are able to anticipate cyber activity and minimize the impact of an attack.

    Implementing effective security within a cloud environment may seem to be a challenging task; however, a strategic plan and the proper integration of people, process, and technology enable organizations to overcome this challenge.

Understanding the AWS Security Model and Services

Protecting and monitoring networks, applications and data is simple if you know and use the right tools

Security is a stifling fear for organizations considering public clouds, one frequently stoked by IT vendors with vested interests in selling enterprise IT hardware and software using security as a catalyst for overall FUD about cloud services. The fears and misconceptions about cloud security are rooted in unfamiliarity and conjecture. A survey of IT pros with actual cloud experience found the level of security incidents relative to on-premise results quite similar. When asked to compare public cloud versus on-premise security, the difference between those saying the risks are significantly lower versus higher is a mere one percent. Cloud infrastructure is probably more secure than typical enterprise data centers, but cloud users can easily create application vulnerabilities if they don’t understand the available security services and adapt existing processes to the cloud environment.

Cloud-security-survey_int-v-public

Whatever the cause, the data shows that cloud security remains an issue with IT executives. For example, a survey of security professionals found that almost half are very concerned about public cloud security, while a 2014 KPMG survey of global business executives found that security and data privacy are the most important capabilities when evaluating a cloud service and that the most significant cloud implementation challenges center on the risks of data loss, privacy intrusions and intellectual property theft.

KPMG-cloud-2014_security-eval

 

KPMG-cloud-2014_adopt-challenges

Unfortunately, such surveys are fraught with problems since they ask for subjective, comparative evaluation of two very different security models, one (on-premise) that IT pros have years of experience implementing, managing and refining, and the other (public cloud) that is relatively new to enterprise IT, particularly as a production platform, and thus often not well implemented. The ‘problem’ with public cloud security isn’t that it’s worse, no, it’s arguably better. Rather, the problem is that cloud security is different. Public cloud services necessarily use an unfamiliar and more granular security design that accommodates multi-tenant services with many users, from various organizations, mixing and matching services tailored to each one’s specific needs.

AWS Security Model

AWS designs cloud security using a shared security model that bisects security responsibilities, processes and technical implementation between the service provider, i.e. AWS, and customer, namely enterprise IT. In the cloud, IT relinquishes control over low-level infrastructure like data center networks, compute, storage and database implementation and infrastructure management to the cloud provider. The customer, i.e. enterprise IT, has control over abstracted services provided by AWS along with the operating systems, virtual networks, storage containers (object buckets, block stores), applications, data and transactions built upon those services, along with the user and administrator access to those services.

AWS_shared-security-model

The first step to cloud security is mentally relinquishing control: internalizing the fact that AWS (or your IaaS of choice) owns low-level infrastructure and is responsible for securing it, and given their scale and resources is most likely doing better than most enterprise IT organizations. Next, AWS users must understand the various security control points they do have. AWS breaks these down into five categories:

  • Network security: virtual firewalls, network link encryption and VPNs used to build a virtual private cloud (VPC).
  • Inventory and configuration: comprehensive view of AWS resources under use, a catalog of standard configuration templates and machine images (AMIs) and tools for workload deployment and decommissioning.
  • Data encryption: security for stored objects and databases and associated encryption key management.
  • Access control: user identity management (IAM), groups and policies for service access and authentication options including multifactor using one-time passwords.
  • Monitoring and logging: tools like CloudWatch and CloudTrail for tracking service access and use, with ability to aggregate data from all available services into a single pool that feeds comprehensive usage reports, facilitates post-incident forensic analysis and provides real-time application performance alerts (SNS).

Using CloudTrail Activity Logs

Organizations should apply existing IT security policies in each area by focusing first on the objectives, the policy goals and requirements, then mapping these to the available AWS services to create control points in the cloud. For example, comprehensive records of user access and service usage are critical to ensuring policy adherence, identifying security gaps and performing post hoc incident analysis. CloudTrail fills this need acting as something of a stenographer recording all AWS API calls, for every major service, whether accessed programmatically or via the CLI, along with use of the management console. CloudTrail records are written in JSON format to facilitate extraction, filtering and post-processing, including third party log analysis tools like Alert Logic, Loggly and Splunk.

CloudTrail so thoroughly monitors AWS usage that it not only logs changes to other services, but to itself. It records access to logs themselves and can trigger alerts when logs are created or don’t follow established configuration guidelines. For security pros, CloudTrail data is invaluable when used to build reports about abnormal user or application behavior and to detail activity around the time of a particular suspicious event.

The key to AWS security is understanding the division of responsibilities, the cloud control points and available tools. Mastering these can allow cloud-savvy organizations to build security processes that exceed those in many on-site data centers.
