What Is Secrets Management?

Secrets management refers to the practices and tools used to secure, control access to, and manage the lifecycle of sensitive digital credentials and keys, commonly referred to as secrets. These secrets can include tokens, passwords, certificates, API keys, and other types of sensitive credentials that determine access to machines and processes.

In order to truly understand the importance of secrets management, it’s essential to understand the concept of machines and machine identities. Machines, in the context of IT and cybersecurity, refer not just to physical hardware like servers or network devices, but also virtual machines, containers, service accounts, microservices, and APIs—essentially, any non-human actor in the digital ecosystem that processes, stores, or transmits data. 

What is Effective Secrets Management?

Effective secrets management is a now a cornerstone of cybersecurity. It plays a pivotal role in safeguarding confidential data, preventing unauthorized access, and ensuring adherence to regulatory compliance. Make sure your secrets management tools and practices cover these basics of best practices.

Prioritizing secrets management is not just a strategic move; it’s a fundamental necessity in today’s interconnected world.

What Are Secrets? Definition and Guide

In the context of Information Technology, “secrets” refer to sensitive data that, if compromised, could lead to unauthorized system access. They serve as the keys to the kingdom, so to speak, granting access to valuable resources within an organization’s IT infrastructure.

What is the difference between a credential and a secret?

While both credentials and secrets provide access to systems, there is a clear difference between the two. 

In simple terms, credentials are typically used for human-to-machine access but can also be used for machine-to-machine access, whereas secrets primarily refer to machine-to-machine access.

What Are The Risks of Not Managing Secrets?

Securing secrets is not just a good practice: it’s a vital part of a robust cybersecurity strategy. 

Secrets represent critical access points to sensitive systems and data, and any compromise of these secrets can result in unauthorized access and potential data breaches. According to the 2022 Cost of a Data Breach Report by IBM, the average cost of a data breach is $9.44 million. Stolen or compromised credentials were not only the most common cause of a data breach, but at 327 days, took the longest time to identify, and cost $150,000 more than the average cost of a data breach.

Risks of Not Properly Managing Secrets

Failure to properly employ secrets management can lead to data breaches, system outages due to unmanaged or expired secrets, and unauthorized system access—all of which can have devastating impacts on a business. 

• Data breaches: In its 2023 Data Breach Investigations Report, Verizon found that use of stolen credentials are in the top five most common causes of breach. Unsecured secrets provide an easy avenue for attackers to infiltrate systems and extract sensitive data.
• System outages: Expired or unmanaged secrets, such as certificates, can cause unexpected system failures. The average cost of IT downtime is approximately $5,600 per minute according to Gartner, but a more recent report by Ponemon Institute raises Gartner’s average from $5,600 per minute to nearly $9,000 per minute.
• Unauthorized system access: Unsecured secrets can provide an open door to malicious actors, allowing them to manipulate systems or data, disrupt operations, or even launch attacks against other organizations.

Given these risks, robust secrets management should be a priority for every organization, regardless of size or industry.

Understanding Secrets, IAM and the Rise of Machine Identities

In the context of Identity and Access Management (IAM), which governs the identification and authorization of users within a system, the concept of machine identities has become increasingly significant. As we witness the rise of machines – including servers, devices, and automated scripts – in digital ecosystems, managing their identities is as crucial as managing human identities.

Each machine is given a unique identity, akin to a digital fingerprint, for secure interaction within a system. These machine identities, validated through digital certificates and keys, are vital ‘secrets’ in the domain of secrets management. They enable machines to securely communicate, execute actions, and access resources, paralleling the usernames and passwords used by human users. In the era of expanding digital infrastructures, safeguarding these machine identities is imperative to prevent unauthorized access and potential security breaches, thereby maintaining the integrity of the entire IAM framework

How Do Secrets Managers Work?

Secrets managers are an essential tool in maintaining secure and efficient handling of sensitive data or “secrets”. Here’s a high-level overview of how they function:

• Centralizing Secrets: Secrets managers usually consolidate all secrets within an organization into one secure location. This enhances the uniformity of security measures across all secrets and simplifies their management.
• Securing Secrets: Security is the core function of secrets managers. They encrypt secrets to protect them from unauthorized access, ensuring that only those with necessary decryption keys can access the information.
• Enforcing Access Policies: Strict access policies are enforced by secrets managers. They use mechanisms like Multi-Factor Authentication (MFA) as well as role-based access controls (RBAC) to ensure that only authorized individuals can access the secrets.
• Automating Secrets Rotation: To enhance security, secrets managers support automated secrets rotation, generating and updating new secrets at regular intervals. This automation maintains high security without adding significant administrative burdens.
• Temporary, Just-in-Time Dynamic Secrets: Some secrets managers can create auto-expiring temporary secrets, which eliminate the danger of standing privileges and ensure that access is unavailable as soon as it is not needed.
• Tracking and Visibility for Governance and Auditing:  Secrets managers provide robust tracking and visibility capabilities, allowing organizations to maintain governance and meet auditing requirements. They enable organizations to track, monitor and log activities related to secret creation, access, and modification, providing an audit trail for compliance purposes. This visibility ensures transparency and accountability, helping organizations demonstrate adherence to security policies and regulatory standards.

What Are The Different Types of Secrets Managers?

There are several types of secrets managers, including open-source, self-deployed, or cloud-based secrets managers. 

Open-Source Secrets Managers: Open-source secrets managers are built on freely accessible source code. They are typically flexible and customizable, allowing you to tailor them to your specific needs. Although open-source tools are popular in the development community, they can often require more resources in terms of setup and management compared to other options. Often, this can be a headache to deploy and maintain for large organizations, and are frequently difficult to scale to more than one team or environment.

Self-Deployed Enterprise Secrets Managers: Self-deployed secrets managers are deployed within an organization’s own infrastructure. This can provide more control over the data and system compared to cloud-based options and might be required for organizations with stringent data sovereignty or regulatory requirements. The drawback is that these systems require significantly more management overhead and hardware resources, and may not scale as easily or cost-effectively as cloud-based alternatives.

Cloud-Based Secrets Managers: While convenient and scalable, the use of cloud-based secrets managers like AWS Secrets Manager, Azure Key Vault, and Google Secret Manager can raise security concerns because these providers have full ownership of the keys used for encrypting and decrypting data,  limiting the organization’s control of their own data. Organizations can explore technologies like Akeyless Distributed Fragmentation Cryptography (DFC)™ to regain control over encryption keys and enhance data privacy and security.

How Do Secrets Management Vaults Work?

In secrets management, a vault is a secure and centralized storage system designed to protect important information. It acts as a safe place where organizations can store their secrets, keeping them private and inaccessible to those who shouldn’t have access. By using a vault for secrets management, organizations can have better control over their sensitive data, reducing the risk of unauthorized access and ensuring the safety of their information.

While the vault has traditionally been a cornerstone of secrets management, the landscape of cybersecurity is ever-evolving, as are the methodologies used to safeguard sensitive information. As organizations grow and their systems become more complex, the demand for a more dynamic and flexible approach to managing secrets also increases.

Why Are Secrets Management Vaults Outdated?

The use of a vault has been a traditional method in secrets management, offering various benefits including:

• Centralized, Secure Storage: Vaults provide a single, secure location to store secrets, mitigating the need for disparate and potentially less secure storage alternatives.
• Access Control: They allow organizations to regulate who can access specific secrets and when, thus improving data security.
• Usage Tracking: Vaults have the capability to monitor and document the usage of secrets, providing a comprehensive history of access and helping maintain compliance.

However, as the digital landscape grows in complexity, the capabilities of traditional vault systems might be challenged. 

With the rapid development of technology and escalating intricacies of IT environments, organizations are starting to consider innovative methodologies. These new strategies retain the advantages of traditional vaults, while also incorporating enhanced adaptability and scalability. They’re designed to keep pace with complex, ever-evolving digital ecosystems, ensuring robust security and compliance without hindering operational efficiency. 

Essentially, these emerging strategies are revolutionizing secrets management, meeting the needs of securing sensitive data in today’s fast-paced technological environment.

Why Is Secrets Management Important to the DevOps | DevSecOps Processes?

In the dynamic environments of DevOps and DevSecOps, secrets management plays a pivotal role. It ensures the security and efficiency of automated deployments while reducing potential risks.

The integration and continuous delivery models characteristic of DevOps and DevSecOps necessitate frequent communication between various tools and systems, often involving numerous secrets. Improper management of these secrets can pose significant security risks.

Moreover, secrets are often shared across multiple teams in a DevOps environment. Without effective secrets management, there’s a risk that sensitive information could be exposed, leading to unauthorized access or even data breaches. This can have severe consequences, including loss of customer trust, financial penalties, and regulatory non-compliance.
