Slack is a popular collaboration platform that allows teams to communicate and work together more efficiently. However, as with any online service, Slack also poses some security risks that must be addressed and mitigated. Read on to learn best practices for Slack security that can help you protect your workspace and data.
With 54.1 million monthly active users and 32.3 million daily active users on the platform, Slack has become an enticing target for hackers seeking to breach and access sensitive data. Hence, companies should consider additional security measures to ensure protection against potential Slack security breaches.
Slack security refers to the measures and policies you implement to safeguard your Slack workspace from unauthorized access, data breaches, malware, phishing, and other threats. Slack security covers both the technical and organizational aspects of using Slack, such as:
Slack security is essential for several reasons, such as protecting confidential and sensitive information, complying with legal and regulatory requirements, maintaining your reputation and trust, preventing potential losses and damages, and enhancing productivity and collaboration.
Securing your Slack workspace can safeguard your data, meet your obligations, build credibility, avoid cyberattacks, and improve your performance.
Slack security consists of several key components that ensure the safety and privacy of your data and communications. These components are:
By implementing these components, you can enhance your Slack security and enjoy the benefits of a secure and productive workspace.
Slack has experienced several security incidents, exposing its users’ data and code. Here are some of the well-known ones:
These incidents show that Slack’s security is insufficient to protect its users from cyberattacks and that users need to take additional measures to improve their security.
Depending on your specific needs and goals, there are many ways to improve your Slack security. However, some of the most common and effective Slack security best practices are:
The challenge lies in implementing a system that can seamlessly manage and control user access to critical information. Find a provider that lets you seamlessly integrate with Slack, providing a foundational layer of preventative controls. It assists in preventing data overexposure, automatically remediating insider threats, and enabling secure business collaboration.
Leverage automated workflows for secure file sharing in Slack to overcome challenges in manual security controls. Integrating solutions like DoControl mitigates data exfiltration risks and ensures compliance. Enhance security by incorporating encryption features and promoting private channels for sensitive discussions.
Simplify vetting third-party integrations with dedicated Slack security solutions. Consolidate and normalize activity events across critical SaaS applications, providing a baseline for normal user behavior. This enables real-time notifications and automated security workflows, streamlining the integration of third-party apps securely.
Use a tool offering real-time notifications and automated actions for robust incident response. It swiftly responds to threats by consolidating activity events, allowing teams to focus on critical projects while automating lower-priority tasks.
Beyond technical solutions, it's also essential to foster a culture of secure collaboration. Focus on high-priority tasks while automating lower-priority ones. Regular training sessions, real-time alerts, and automated responses contribute to building a security-aware organizational culture.
Depending on your sector and location, you may need to follow specific standards for data security on collaboration platforms, such as GDPR, HIPAA, PCI DSS, etc. By aligning your Slack usage with these standards, you can avoid legal risks, protect your data, and demonstrate trustworthiness to your customers and partners.
As mobile collaboration becomes increasingly prevalent, you must implement mobile device management (MDM) policies. Promote the adoption of device passcodes and biometric authentication among users to enhance security measures. Utilizing Slack's mobile security settings further enhances the management and control over mobile devices.
Consider partnering with a SaaS Security Platform for consolidated activity events. It establishes a baseline for normal user behavior, enabling Slack webhooks for real-time notifications in automated workflows. Lower-risk events go to individual actors, while higher-risk events trigger immediate action from relevant teams.
Establishing granular data access policies is essential, restricting unauthorized parties from accessing specific files. Real-time alerts and automated responses enhance the security posture, ensuring sensitive information remains within authorized boundaries.
Establish secure data retention policies for Slack to enable you to monitor and control user activity. Enforce policies to prevent perpetual access to sensitive files across organizational Slack channels.
Continuing to fortify your collaborative workspace, it's crucial to implement additional Slack security best practices, such as user emails and domain verification or backing up your data.
Verifying user emails and domains is a way to ensure that only authorized and trusted people can join your Slack workspace. You can do this by setting up a signup mode for your workspace that allows anyone with an approved email domain to join your workspace automatically or by requiring admin approval for all invitations.
Some members of your Slack workspace, such as contractors, interns, or clients, may only need access to certain channels or messages. Guest accounts are a great way to manage who has access to the information they need in your workspace without giving them full access.
Session durations are the length of time that users can stay signed in to Slack without having to re-enter their password or verification code. It helps you limit the risk of unauthorized access to your workspace if a user’s device is lost, stolen, or compromised.
Deactivating old accounts is a way to remove access to your workspace from users who no longer need it, such as former employees, contractors, or guests. Doing so can free up space, reduce costs, and prevent potential security issues.
Encrypting and backing up your data is a way to protect your data from unauthorized access, loss, corruption, or deletion. You can ensure your data is secure and recoverable in case of a cyberattack, disaster, or human error.
It’s a way to keep up with the latest trends and developments in Slack security and the best practices and recommendations from Slack and other experts. You can learn new ways to improve your Slack security and identify and address potential issues or vulnerabilities.
Handle any security issues or breaches in your Slack workspace, such as unauthorized access, data leakage, malware infection, phishing attacks, etc. You can minimize the impact and damage of the incident, as well as prevent recurrence and escalation.
Reviewing and auditing your security settings is a way to check and evaluate the effectiveness and performance of your Slack security measures and policies. You can identify and address any gaps, weaknesses, or risks in your Slack security and improve and optimize it.
