Cloud Security Checklist

Cloud Security Checklist

Cloud Security Checklist. Everything CSO needs to know

With droves of today’s organizations moving to cloud environments at a rapid pace, there is no question that cloud infrastructure is a viable solution for today’s production workloads. The cloud has certainly matured as a platform and solution for today’s business-critical applications. Organizations have chosen to run not only production virtual machines on top of cloud infrastructure, but also business services such as email and file storage. The cloud revolution has brought about significant changes in the way that businesses today think about provisioning infrastructure. It has also changed the methodologies used in traditional infrastructure that exists on-premises.

A concern with literally all technical infrastructure today, whether it exists on-premises or in the cloud, is security. Cybersecurity has been a major concern with cloud infrastructure since its inception. It was the primary barrier to entry for most organizations with cloud infrastructure in the early days. While cloud has matured greatly and public cloud vendors have drastically improved security measures, technologies, services, and the overall security infrastructure, cloud security is certainly still one of the major concerns with cloud infrastructure of all types. Even though customer confidence in cloud security is at an all-time high, it must be at the forefront of the overall cloud migration plan and ongoing “day 2” operations.

Businesses today do not want to be among the growing list of victims of data compromise, data leakage, or other cybersecurity event. Businesses today need to take a strong stance on cloud security. A cloud security checklist can be a great place to start with implementing security in the cloud as well as useful in incorporating proper security measures into ongoing operations. Let’s take a look at an effective cloud security checklist and see how it can assist organizations in securing their cloud infrastructure.

Meeting Cloud Security Checklist Objectives Effectively

When thinking about security in the cloud, one of the major mistakes an organization can make when considering migrating workloads and data to the cloud is failing to think about security. A huge problem can “snowball” for businesses who start out beta testing cloud as a potential solution, only to transition that beta into production without properly thinking about or designing security into the solution. It is extremely valuable for businesses to have a cloud security checklist to follow when migrating to cloud environments as well as carrying on “day 2” operations. This helps organizations to cover the major areas that need to be considered when thinking about cloud migration. What are the items on an effective cloud security checklist?

  • Cloud Identity and Access Control
  • Enforcing current on-premises policies in the cloud
  • Cybersecurity Protection
  • Data Leak Prevention
  • Auditing and Alerting
  • Business Continuity and Disaster Recovery – Backups and Recovery

Let’s take a look at each of these critical areas of cloud security and why organizations need to carefully consider each as they make plans and execute a plan to migrate to the cloud.

Identity and Access Control in the Cloud

One of the most often-overlooked areas of security is access permissions. All too often businesses assign more permissions or system rights to user accounts than the accounts need to have. Why does this create problems with security? One of the lowest hanging fruits that attackers generally try to exploit is user credentials. User accounts need to have appropriate permissions to only the resources they should have access to. This lessens the security scope of those credentials. For example, if a user account is perhaps assigned administrative privileges and this is way beyond what the user account truly needs, any compromise of this account now gives an attacker full control of the system, with administrative privileges.

Cloud Identity and Access Control is central to an effective cloud security strategy and overall cloud security checklist. Cloud IAM is extremely important in that it is the mechanism that defines “who” has “what” access for “which” resource. The who are members, the what is roles and the resources are anything we want to grant permissions on in the public cloud.

User identity management and verification is extremely important when it comes to public cloud environments. Since users connect from any number of devices and networks, Cloud Identity and Access Control plays a key role in verifying that users are who they say they are. Cloud Identity and Access Management plays a key role in the cloud security checklist in that it allows organizations to have the following capabilities in regards to identity, access control, and security:

  • Identity and Access control
  • Permissions and roles
  • Policy Based Access
  • Intuitive, single management interface
  • Auditing
  • Automation

Going back to the idea of “least privilege as mentioned above, Cloud Identity and Access Control allows organizations to effectively implement the idea of least privilege in terms of creating roles, assigning permissions to those roles, and then adding users to those roles.

Best Practices for Cloud Identity and Access Control:

  • Use Predefined roles over Primitive roles which are much more granular
  • Treat each part of an application controlled by Identity and Access Management as a separate trust boundary
  • Grant roles at the smallest scope needed – “least privilege”
  • Restrict the number and specifics of who can operate as a service account as these types of accounts generally have more permissions
  • Restrict who can create service accounts
  • Be restrictive on granting owner role to members as this allows the modifying and managing of the Identity and Access Control policy for that resource

Organizations migrating to or already housed in the cloud, need to closely consider the management of identity and access permissions and understand the different identity tools and offerings from various public cloud vendors. Cloud Access and Identity and Access Control allows managing permissions and assigning users to roles that can then be assigned to resources. The idea of least privilege should certainly be among the top priorities when architecting a permissions and access control methodology.

Enforce Current On-Premises Policies in the Cloud

A great place to start with creating access and other usage policies with cloud environments is to look at the current policies that are in place with on-premises environments if these have been effectively implemented. Many organizations may struggle to understand how usage and other access policies can be implemented in the cloud in a standardized way that is homogeneous to end users. By using a technology called a Cloud Access Security Broker or CASB, organizations can implement and enforce policies across the organization in the cloud, effectively and efficiently.

The best CASB solution is based on an API-based CASB approach. API-based CASBs have very few limitations and provide standardized access to end users no matter which network they are coming from and what type of device they are using to access cloud resources.

API-based CASB solutions are a much more seamlessly integrated approach to CASB technology in the cloud as opposed to a firewall-based approach. Using the API-based integration, the solution scales and performs extremely well despite changing end user load and requirements. Additionally, no additional network configuration is required from an end user/device perspective such as VPN configuration.

API-based CASBs allows for the following 9 benefits in regards to enforcing policy in the cloud:

  1. Intelligent, machine-learning enabled algorithms that scan and protect cloud environments
  2. Discovering risky applications interacting with the cloud environment
  3. Scans and discovers user accounts that may involved with high-risk behavior or possibly have been compromised by an attacker based on pattern analysis
  4. Protects cloud environments from “Shadow IT” operations
  5. Can enforce encryption and device-based profiles
  6. Allows aligning cloud usage and activity policies with on-premises policies
  7. Helps to protect against data leak activities such as the unsanctioned downloading of data from organization’s public cloud environment and copying that data to a personal public cloud environment
  8. Scans for and remediates sensitive data exposure such as credit card or social security numbers
  9. Scans and protects against ransomware and other malware that may infect cloud environment data

These and other powerful benefits make the API-based CASB technology a solution that organizations will want to strongly consider when looking at their cloud security checklist to ensure their data is secure. Policy enforcement is a great way to strengthen the overall security posture and plays into the next area that organizations want to consider for their cloud security checklist, cybersecurity.

Cloud Cybersecurity

Cybersecurity is the methodology that protects electronic data from cyber criminals. Today’s threats to digital resources come from a wide range of attack vectors. However, criminals today are looking to steal very valuable data that is potentially housed either on-premises or in the public cloud. Businesses who are in the infancy of locating data and services in the cloud may be under the misconception that having data or services in the cloud is inherently more secure. However, this is not true. A simple misconfiguration of permissions or accidental exposure of data to the public Internet can serve up very sensitive data that is wide open for consumption. Even if businesses do not misconfigure or mistakenly make data openly available, this is the prize that is sought out by hackers.

A true security concern with housing data and services in the public cloud can simply be the lack of proper knowledge on how to secure cloud resources when compared to on-premises resources. Moving from on-premises to the cloud can require a new level of expertise and skillset that may take time to acquire or potentially hiring the personnel with that expertise. Therein lies the danger of moving forward with a cloud implementation that may not be architected correctly from a security perspective.

Cloud cybersecurity is an essential operation that must be taken seriously from all levels of the organization. Most of today’s businesses operate digitally at least at some level. Protecting those digital resources and data is now a key business-critical process.

What aspects are involved with cybersecurity? Like security in general, proper cybersecurity initiatives are multi-layered. They require various aspects all working together harmoniously to be successful.

What Successful Sybersecurity Involves

  1. People – Personnel need to be trained with security as a thought process. We live in a new world that must be focused on security. Training personnel to understand the security implications and necessity of creating strong passwords, screening attachments in email, and other behavioral security benefits.
  2. Processes – Organizations must have the policies and processes in play that allow successfully dealing with both cybersecurity attacks that are successful and those that are only attempts. Learning from each event plays a major role in successful cybersecurity.
  3. Technology – In today’s very complex and technology centric environments, businesses must use powerful technology solutions to solidify security solutions that secure computers, mobile devices, network equipment, servers, etc. This includes cloud environments.

With cloud environments, having a technology solution that is capable of utilizing powerful machine learning “intelligence” can be a huge benefit. Machine learning allows creating a baseline of normal activity and then being able to “learn” or recognize anomalies in those normal baselines and pinpoint potential behavior or activity that is not characteristic of normal usage. This helps to quickly identify activity that may otherwise be undetected. For cloud environments, this may be extremely difficult to do manually with the distributed nature of the cloud and access coming from any variety of networks and devices. API-based CASBs as discussed earlier, are a powerful mechanism to implement technology utilizing machine learning. When thinking about cybersecurity, these solutions can watch cloud environments 24x7x365 and ensure electronic information in the form of your data is kept safe.

Cybersecurity encompasses the training of personnel, implementing processes, and technology that allow securing digital infrastructure. Today’s environments both on-premises and in the cloud have to be vigilant to new and existing threats both externally and internally. An extremely important part of securing cloud environments and that should be a major consideration on a cloud security checklist is protecting against data leak. What is data leak and why is it an important component of the cloud security checklist?

Protect Against Data Leak

Of all the cybersecurity events that generally affect organizations today, arguably the most damaging is data leak. What is data leak and why is it an important part of the cloud security checklist? Data leak is any sharing or transmission of data in an unauthorized way, outside of sanctioned use. Data leak is an extremely important topic for businesses to consider as it can lead to the most disastrous consequences in the sense of long-term effects as well as damage to customer confidence and overall brand reputation. Data leak events are generally the events that lead to businesses making headlines in the news for all the wrong reasons. All too often, we hear about organizations that leaked credit card information unintentionally or had a data breach that led to the dissemination of millions of customer names and sensitive information. Data leak events can be the result of actions both unintentional and intentional.

Data leak can happen unintentionally when an employee attaches a spreadsheet with sensitive information to an email and accidentally sends the email outside the organization to an untold number of recipients, or sends the email to the wrong distribution group internally. A disgruntled employee may intentionally disseminate customer information to a competitor or attempt to leak data for a sum of money to a malicious third-party. Malware can be used by attackers to leak data outside the organization by running malicious code on an end user system and compromising data locally or housed on the network. Phishing attacks via emails are still highly successful, even though they have been around for quite some time. By tricking end users to click links embedded in email, they are able to “phish” information from end users, including even user credentials and other sensitive information.

With more information stored in the cloud now than ever before, organizations considering moving to the cloud or already housed there need to seriously consider what measures they have in place to prevent data leakage in the cloud. The lack of direct control in the cloud vs. the control that organizations are able to maintain on-premises can be a challenge. Not only do businesses need to control general data leakage from the cloud for unsanctioned use, they need to especially be concerned about data leakage of sensitive information. Sensitive information can include information that violates compliance regulations, etc. This type of information can include credit card numbers, social security numbers, HIPAA or other information that should be treated as sensitive. It should be a priority on the cloud security checklist to have the processes and technology in place to prevent data leak in general as well as sensitive data control.

Auditing and Alerting

All too often when dealing with security, the response to security events is reactive instead of proactive. Generally, a security breach or cybersecurity event is discovered and then responsive action takes place as a result. When thinking about either migrating to the cloud or for those organizations who have already begun their migrations, the cloud security checklist must contain items related to auditing and alerting.

Unfortunately, for most, a breach is only learned about when the damage is already done or data has already been leaked in mass. What can help prevent these types of cybersecurity disasters? Proper auditing and alerting are powerful tools against security compromise that can happen both on-premises and in the cloud. These actions should be proactive in nature. Proper auditing and alerting are mechanisms when done right that can detect the breach event when it happens, and then proactively alert administrators to the events that have unfolded. With API-based CASBs there can also be a series of proactive remediation actions that get triggered in response to the events.

Again, let’s consider the advantage here of machine learning enabled API-CASB technology that can constantly monitor the cloud environment, 24x7x365. It creates a baseline of normal behavior and activities. When those fall outside the normal thresholds for the cloud environment for a particular user or activity, administrators can be proactively alerted. What if there are dozens of failed login attempts or a particular user? This could indicate a brute force attempt to compromise user credentials. What if successful logins come from an unusual geolocation for a particular user? This could indicate the credentials have been compromised by an attacker coming from outside the normal geolocation for the legitimate user. These are merely a couple of examples of how normal traffic and activity can be audited and used to indicate potential cybersecurity events. Then appropriate alerting can take place based on the event.

Proper auditing and alerting are essential to a successful cloud security checklist. They allow organizations to have the visibility and appropriate responses to activities that may otherwise go unnoticed. However, it can be challenging to implement this type of effective auditing and alerting for businesses attempting to utilize the native tools and other features offered by their public cloud vendor./p>

Business Continuity and Disaster Recovery – Backups and Recovery

One of the most often overlooked areas in security is business continuity and disaster recovery. In fact, many do not even consider or list out business continuity and disaster recovery as items included with security. However, not considering BC/DR as part of any successful security checklist can be a grave mistake. When a security event leaves data destroyed or missing, when ransomware corrupts massive amounts of data, and when a disgruntled employee intentionally deletes business-critical files, the only mechanism that can allow data to be recovered at that point is data backups.

While backups are traditionally considered in on-premises IT infrastructure and have been a staple of normal daily operations for most companies, thinking about backups seemingly get missed in cloud. There has long been a mystical idea that cloud environments make thinking about backups and protecting your data obsolete. This could not be further from the truth. While the major public cloud vendors today have impressive high availability and hardware and network redundancy that most enterprise environments could only dream of, this does not mean your data is indestructible in the public cloud. Public cloud data is still subject to many of the same dangers as on-premises data. These include ransomware, intentional deletion, accidental deletion, data leak, and many other concerns.

The problem for some time now has been that public cloud vendors do not provide a native data protection mechanism for businesses to protect data and resources housed in the public cloud. This means that many businesses are rolling the dice and either do not have backups implemented in the cloud at all, or have only minimal data protection configured by using a third-party that may not natively integrate with their public cloud environment.

With more and more data and services moving to the cloud, businesses have to be able to restore data or services that may be affected or lost. Data backups needs to be a versioned copy of files and data that allow businesses to have an effective way to roll back in time to a particular version or recover files or other data that have been deleted altogether.

Cloud data backups, backup strategy and restores are an essential part of the cloud security checklist in that data is able to be both protected and recovered as needed. Making use of a technology solution that allows having multiple versions of data stored in the cloud, the ability to recover deleted items, the ability to protect not only files but also other services such as email that are commonly stored in the public cloud, is essential. In today’s cloud-centric world, businesses have to be able to support business continuity or the ability to withstand failures and other disasters and continue operating, despite where data is housed.
