Multi Factor Authentication (MFA) and the human risk factor

The basic prerequisite for a company's survival is protection against a wide range of threats - both internal and external. Cyber criminals use a wide range of attack methods to penetrate systems and steal valuable data. Some of these methods are highly technical and require specialized knowledge. However, the majority of attacks are aimed at misusing stolen employee credentials, for example through phishing attacks.

 

A basic but still highly effective method to prevent the misuse of stolen credentials is Multi-Factor Authentication (MFA). To fully understand the effectiveness of MFA, it is essential to gain a deeper insight into the human factor and its role in IT security.

 

The human risk factor in IT security

At the center of many cybercriminal activities is the human being as the "weakest link" in the chain. Despite advanced security technologies, human error, ignorance or negligence can lead to serious security breaches. Here are some aspects where the human factor can compromise IT security:

 

• Inadequate password practices: Many users use weak passwords - or the same passwords for multiple user accounts. This makes it easier for attackers to gain access to different systems as soon as they capture a password.
• Phishing attacks: Phishing remains one of the most effective methods of attack. Phishing focuses on manipulating people into revealing confidential information. By using deceptively real-looking emails or login pages, attackers can trick users into entering their credentials on malicious websites.
• Lack of training and awareness: Many users and even IT professionals are not sufficiently informed about the latest threats and best practices in cybersecurity.

 

Once inside the system, the attacker can exploit further local vulnerabilities, access sensitive data, manipulate systems and create further attack vectors to establish a persistent presence on the network. This underscores the need to implement robust security measures such as multi-factor authentication (MFA) to prevent unauthorized access in the first place.

The solution: Multi-Factor Authentication (MFA)

MFA is a security mechanism that confirms a user's identity by validating two or more independent factors before granting access to a particular resource or system.

 

The possible authentication methods can be divided into three categories:

 

Knowledge-based authentication - "Something you know"

This refers to knowledgethat is only known to the user, such as passwords, PINs or security questions.

Possession-based authentication - "Something you have"

This refers to something physicalthat the user possesses, such as a smartcard, security token or smartphone.

Biometric authentication - "Something you are"

This refers to biometric features of the user, such as fingerprint, facial recognition or iris scan.

 

The restriction to a single authentication factor (Single Factor Authentication - SFA) can lead to security gaps in various scenarios.

Traditional login procedures with username and password only rely on the "knowledge" category. A cybercriminal can easily gain access to the company network if an employee uses the same user name and password for both an online service and the company network and the online service is compromised.

Another example is the sole use of a security token or smart card. Such login procedures rely solely on possession. If the card is stolen, the thief gains immediate access to protected systems or data, provided no other authentication factors are required.

Regardless of whether possession or knowledge is used as an authentication factor in the examples, these can easily be compromised or lost. However, if two or more of these factors are combined to secure the login process, security increases considerably - this is known as multi-factor authentication (MFA).

 

Why is MFA important?

• Increased safety: MFA offers significantly higher security compared to SFA. Even if an attacker is able to compromise one of the authentication factors, e.g. the password, the additional factor will prevent them from gaining access.
• Protection against phishing and other cyber attacks: MFA can effectively protect against phishing attacks because even if the password is disclosed, the attacker does not have the additional authentication factor.
• Regulatory compliance: Many industries and countries have laws and regulations that require the use of MFA to increase data security and ensure the protection of personal information.

 

Checklist - Best Practices

The implementation of Multi-Factor Authentication (MFA) is a crucial step towards improving cyber security in a company. However, simply enabling MFA is not enough. It's important to follow best practices and regularly review and adjust the MFA strategy to ensure it remains effective. Here are some recommended best practices:

 

1. robust password policies

• Complex passwords for service accounts: Ensure that passwords for service accounts are complex to increase their resistance to password cracking attempts.
• Uniqueness: Use a unique password for each service account to prevent a compromise from affecting multiple accounts.
• Regular password changes: Encourage users to change their passwords regularly to reduce the risk of compromise.
• Password management tools: Use password management tools to make it easier to create and store secure passwords.

 

 

2. implementation MFA

• Broad application: Implement MFA wherever possible to provide an additional layer of security that prevents misuse of accounts even in the event of credential compromise.
• User-friendly MFA solutions: Choose MFA solutions that offer a good balance between security and ease of use to encourage adoption.
• Training & Awareness: Educate users on the relevance and effective use of MFA so they can identify phishing attacks and prevent password theft.

 

 

3. current threat situation

• Stay up to date: Use up-to-date threat intelligence to understand the latest methods of attackers who specialize in first access and better respond to their strategies, techniques and approaches.
• Regular reviews and updates: Review and update your MFA strategies regularly to ensure they keep pace with evolving threats.

 

 

Next Steps

Implementing MFA is a critical step in addressing the human risk factor in IT security. By validating two or more independent factors before accessing certain resources or systems, MFA provides a robust barrier against the exploitation of human error or negligence. Even at a time when cyber threats are becoming increasingly sophisticated, MFA retains its critical importance and effectiveness. Yet it is often not consistently implemented for all employees. At IT-HAUS GmbH , we can help you implement MFA across your organization without compromising the comfort of your employees.

But the journey to improving IT security does not end with the implementation of MFA. We also have tailor-made solutions for the next steps on the way to more comprehensive IT security.
