MFA for Shared Accounts To Eliminate Security Risks

Nowadays, cybersecurity is a top concern for businesses and individuals alike. As threats evolve, so must our protection methods. One powerful tool in the security arsenal is Multi-Factor Authentication (MFA).

This blog explores how Multi-factor authentication software can significantly enhance security for shared accounts and admin access, two areas that are often vulnerable to attacks.

The Rise of Shared Accounts and Their Inherent Risks

Shared accounts have become increasingly common in many industries and households. They offer convenience and potential cost savings, but they also introduce significant security risks that need to be addressed. Some common examples of shared accounts include:

Social media accounts for businesses
Company credit cards and financial accounts
Shared digital tools and software licences
Streaming services shared among family members or friends
Cloud storage accounts used by multiple team members

While shared accounts can be practical and cost-effective, they present several serious security challenges:

Increased vulnerability to hacks and unauthorised access
Difficulty in managing access when users leave or roles change
Lack of accountability for actions taken within the account
Higher risk of password exposure due to multiple users
Potential for credential stuffing attacks if passwords are reused

MFA for Shared Accounts

Implementing MFA for shared accounts can dramatically improve security without sacrificing the convenience that makes shared accounts attractive. Here's how MFA for multiple users can effectively address the main risks associated with shared accounts:

Enhanced Protection Against Unauthorised Access

With MFA in place for shared accounts, even if a password is compromised, an attacker would still need additional factors to gain entry.

This significantly reduces the risk of any unauthorised access, especially for high-value shared accounts like financial services, company social media profiles, or shared cloud storage. MFA for shared accounts acts as a powerful deterrent against brute force attacks and password-guessing attempts.

Improved User Management and Access Control

Multi-factor authentication software for shared accounts often includes features that make it easy to control user access. Administrators can quickly add or remove users, ensuring that only current authorised individuals have access to the shared account.

This granular control is especially valuable when team members leave or change roles within an organisation.

Better Accountability and Audit Trails

MFA systems typically log which specific user accessed the account and when creating a clear audit trail. This increased visibility makes it easier to track actions within the shared account and attribute them to individual users.

In case of any suspicious activity, this audit trail becomes invaluable for incident response and forensic analysis.

With MFA in place for shared accounts, users are less likely to share passwords casually, as the additional factors make it more difficult to pass along access informally. This reduction in password sharing helps mitigate the risks associated with credential leakage and unauthorised access.

Protection Against Credential Stuffing Attacks

Shared account MFA protects against credential stuffing attacks, which occur when attackers use stolen credentials from one provider to access other accounts. Even if a shared account's password is compromised in a data breach, the additional authentication factors prevent easy account takeover.

MFA for Shared Accounts: Best Practices

To maximise the benefits of MFA shared accounts, consider these best practices:

Choose Strong MFA Methods: Opt for more secure MFA options like FIDO2 security keys, biometrics, or authenticator apps rather than SMS-based codes, which can be vulnerable to interception.
Educate Users: Ensure all users understand the importance of MFA and how to use it properly. Conduct regular training sessions on MFA for shared accounts to keep security awareness high.
Regular Access Reviews: Periodically review who has access to shared accounts and revoke access for those who no longer need it.
Enable Least Privilege Access: Ensure users only have the level of access they need within shared accounts. Not every user needs full admin rights.
Implement Risk-Based Authentication: Consider using adaptive MFA that adjusts authentication requirements based on factors like device, location and user behaviour.
Regular Security Assessments: Conduct periodic security assessments of your MFA implementation for shared accounts to identify and address any vulnerabilities.

The Critical Importance of Securing MFA for Admin Accounts

While MFA is crucial for all accounts, it's particularly vital for admin accounts. Administrators often have the keys to the kingdom, with access to data and critical systems. This elevated access makes admin accounts prime targets for cybercriminals.

Here's why MFA for admin accounts is absolutely non-negotiable:

High-Value Targets for Attackers

Admin accounts are the holy grail for attackers. Compromising an admin account can potentially give access to an entire network or organisation's data. MFA adds a crucial layer of protection against these high-stakes attacks, making it exponentially more difficult for unauthorised users to gain admin-level access.

Privileged Access and System-Wide Impact

Admins often have the ability to make system-wide changes, modify security settings, and access sensitive data across the organisation.

MFA ensures that this powerful access is only granted to the right individuals, even if passwords are compromised. This is especially critical in preventing insider threats or accidental misuse of admin privileges.

Setting a Strong Security Culture

When admins use MFA, it sets a strong precedent for the rest of the organisation. It demonstrates that security is a top priority, even for those with the highest level of access.

Compliance Requirements

Many regulatory standards and compliance frameworks explicitly require MFA for privileged accounts. Implementing MFA for admin accounts helps organisations meet these compliance requirements and avoid potential penalties.

Protection Against Advanced Persistent Threats (APTs)

Admin accounts are often targeted by sophisticated APTs. MFA provides a strong defence against these long-term, stealthy attacks by making it much harder for attackers to maintain persistent access.

Implementing MFA for Admin Accounts: Best Practices

To ensure the most effective protection for admin accounts, follow these guidelines:

Mandatory MFA: Make MFA compulsory for all admin accounts without exception. This should be enforced through technical controls and policy.
Use the Strongest Methods: Implement the most secure MFA options available, such as hardware security keys or biometric factors. Avoid less secure methods like SMS-based codes for admin accounts.
Regular Security Training: Provide ongoing security awareness training for admins, focusing on the latest threats, social engineering tactics, and best practices for using MFA.
Audit Admin Actions: Implement comprehensive logging and monitoring of admin activities to detect any suspicious behaviour quickly.
Rotate Admin Credentials: Regularly update admin passwords and MFA credentials to minimise the risk of long-term compromise. Consider using Privileged Access Management (PAM) solutions to automate this process.
Implement Just-in-Time Admin Access: Use tools that provide temporary, elevated privileges only when needed, rather than permanent admin access. This reduces the attack surface and exposure time of admin accounts.
Separate Admin and Regular Accounts: Ensure that administrators use separate accounts for their day-to-day activities and admin tasks. Apply MFA to both types of accounts.

Overcoming Common MFA Challenges for Shared and Admin Accounts

While MFA offers significant security benefits, it's not without its challenges. Here are some common issues and strategies to address them:

User Resistance

Some users may resist MFA, viewing it as an inconvenience. To overcome this:

Teach users on the importance of MFA and the risks it mitigates
Choose user-friendly MFA methods that balance security and convenience
Gradually introduce MFA, starting with the most critical accounts
Highlight the personal benefits of MFA, such as protecting personal data and reputation

Technical Difficulties

Users may encounter issues with MFA setup or use. To mitigate this:

Provide clear, step-by-step instructions for setting up and using MFA
Offer multiple MFA options to accommodate different user preferences and device capabilities
Ensure IT support is readily available to assist with MFA-related issues
Conduct hands-on training sessions for users to familiarise them with MFA processes

MFA Fatigue

Constant MFA prompts can lead to user fatigue and potentially result in careless approvals. To combat this:

Implement risk-based authentication that only triggers MFA for suspicious logins
Use adaptive MFA that learns user behaviour to reduce unnecessary prompts
Consider implementing single sign-on (SSO) solutions to reduce the number of times MFA is required
Use push notifications or biometrics for a smoother user experience

Integration Challenges

Integrating MFA across diverse systems and applications can be complex. To address this:

Choose multi-factor authentication software with broad integration capabilities
Work with vendors to ensure smooth integration with existing systems
Consider using identity federation to streamline MFA across multiple applications

Recovery and Backup Methods

Users may lose access to their MFA devices or factors. To prepare for this:

Implement secure account recovery processes that don't compromise security
Provide backup MFA options, such as backup codes or secondary devices
Educate users on the importance of keeping recovery options up to date
