Credential handling and service accounts
1. Credential handling and service accounts
You may come across security practices in your everyday life. For example, businesses lock their doors when they close for the day and often keep security cameras on-premises. You can compare these business security practices with a cloud security team’s security principles to keep their organization’s services and accounts safe. In this video, we'll discuss important topics related to security risks, and best practices to help keep systems and data secure and protected. Specific security principles we’ll cover include credential management, secrets management, non-interactive access, and security protocols to protect your systems from security risks. As a cloud security professional, credential management is a good place to start. The risks associated with unauthorized access to data are primarily because of inadequate credential management practices. If your organization’s users create weak passwords, share their credentials, or fail to change credentials regularly, threat actors can easily gain access to your systems. To avoid such risks, it's important to require strong and unique passwords for all user accounts, and require users to regularly change passwords. Users can also use a password manager to securely store and manage their credentials. Another important concept is secret management. Secrets are sensitive information like Application Programming Interface, or API keys, passwords, and certificates that are used to authenticate and authorize access to systems. Your cloud security team will want to manage your organization’s secrets to prevent threat actors from compromising sensitive information, which may lead to negative consequences. Best practices for managing secrets include using a centralized secret management tool, strong encryption methods to protect them, and regular rotation of API keys, passwords, and certificates. This way, unauthorized users are unable to use secrets to exploit services or gather data. Non-interactive service accounts are another security risk that your security team needs to address. These accounts are created for automated processes and services and are often overlooked. If not properly managed, they can provide an easy entry point for malicious actors to infiltrate your systems. To mitigate this risk, it's important to regularly review and audit these accounts, rotate keys associated with service accounts regularly, and limit their privileges. Now that we’ve covered some primary security risks, let’s dive into some important security protocols that can help protect your systems. mTLS, OAuth, and OpenID are three common protocols that provide secure communication between different systems and services. Let's explore each of these protocols and understand their role in securing user communication and network access. mTLS, or mutual Transport Layer Security, is a protocol that provides mutual authentication and encryption between servers. It's a variation of the Transport Layer Security, or TLS protocol, that secures communication between a client and a server. With mTLS, both the client and the server authenticate each other, ensuring that the communication is secure and private. This helps prevent potential breaches or attacks, and ensures that only authorized parties can access the information being exchanged. Open Authorization, or OAuth, is a method that allows users to grant applications access to their information on other sites or systems without the need to share their passwords. For example, if you want to allow an application to access your Google Drive account, you can use OAuth to securely authorize the application to access your account without sharing your credentials. This ensures that your credentials will not be compromised and you have control over the access given to the application. Finally, OpenID is a protocol that is used for single sign-on functionality, allowing users to authenticate once and access multiple services. The process involves the user authenticating with an identity provider in exchange for an identifier. This identifier can then be used on another site or service, without the user having to authenticate on that site or service for a second time. This simplifies the login process for users and reduces the risk of password fatigue and credential reuse. It's critical to implement best practices for credential management, secrets management, non-interactive access, and security protocols to protect your systems from security risks. By following these practices, you can ensure that your systems and data are secure and protected, allowing the appropriate people to reach the information they need.2. Let's practice!
