Strategy 1: Device and Browser Fingerprinting

What is device and browser fingerprinting

Device and browser fingerprinting is a technique used to uniquely identify and track user devices and browsers based on their characteristics. This method helps to recognize patterns and anomalies that can indicate fraudulent activities or unauthorized access attempts.

How does it work

Device and browser fingerprinting works by collecting device-specific properties, such as operating system, browser version, screen resolution, and installed plugins, among others. These properties are then analyzed and compared against a database to identify unusual patterns and potential threats.

Pros & Cons

Pros:

• Detect and mitigate issues like credential stuffing and insider threats: Device and browser fingerprinting can help identify patterns indicative of malicious activities, such as multiple failed login attempts or unexpected device/browser combinations.
• Monitor multiple account creation and unusual login behavior: By tracking the devices used to access accounts, it is possible to detect if the same device is being used to create multiple accounts or if unusual login patterns emerge.

Cons:

• Can be bypassed by fraudsters using advanced fingerprinting obfuscation techniques: Determined attackers can manipulate their device and browser properties to avoid detection, rendering this technique less effective in some cases.

Tactical implementation

To implement device and browser fingerprinting, follow these steps:

1. Integrate fingerprinting libraries in the software stack: Include established libraries, such as OpenWPM and FingerprintJS. These libraries will assist in gathering device and browser-specific properties needed for identification.

   
   

2. Collect and analyze data to flag suspicious activities: Once the fingerprint information is collected, analyze the data for unusual patterns and anomalies that could indicate fraudulent activities. Set up automated systems to compare gathered fingerprints against known fraudulent patterns, or establish thresholds for acceptable variations in user behavior.

   
   

3. Implement additional authentication measures for flagged actions: If a user's device or browser fingerprint raises suspicion, require additional authentication steps, such as two-factor authentication (2FA). This will help to ensure the user is legitimate and not an attacker attempting unauthorized access.

   
   

By integrating device and browser fingerprinting into your SaaS applications and platforms, you can better shield user data and maintain the integrity of your systems, all while giving you valuable insight into fraudulent activities or suspicious user behaviors.

Strategy 2: Impossible Travel

By identifying cases where users appear to log in from multiple, disparate locations within an unrealistic time frame, this approach can help flag potential security threats for further investigation.

Pros & Cons

Pros:

• Identify potential unauthorized access: Detecting impossible travel patterns allows SaaS professionals to take prompt action to secure affected accounts, notify users of potential breaches, and minimize harm.
• Prompt action to secure affected accounts: By quickly detecting and reacting to potentially unauthorized access, this strategy helps maintain data integrity and preserve trust in your SaaS system.

Cons:

• Limited effectiveness in cases of sophisticated proxy usage: While impossible travel detection can identify basic attempts at unauthorized access, it may struggle to detect more advanced techniques, such as the use of proxy servers or VPNs to obfuscate the true location of the user.

Tactical implementation

1. Implement IP geolocation tracking in the authentication process: As users authenticate to your SaaS application, track their IP addresses and associate geolocation data with each login. Use this information to monitor patterns of access and identify any impossibilities that warrant further investigation.
2. Set up alert systems for flagged logins: When the impossible travel detection system identifies suspect behavior, it should generate an alert. This will enable your security team to respond rapidly to potential security incidents, minimizing any potential damage.
3. Enforce additional authentication or temporary account suspension: In cases where suspect logins are detected, consider implementing additional security measures, such as two-factor authentication, to verify the user's identity. Alternatively, you might choose to temporarily suspend the account, prompting the user to contact your support team for assistance in re-establishing access. This approach can help protect your SaaS system from unauthorized access while minimizing negative impacts on user experience.

By implementing an impossible travel strategy, SaaS professionals can effectively detect and mitigate instances of unauthorized access, helping to maintain the integrity of user data. However, this technique should be accompanied by other data integrity strategies to ensure a comprehensive approach to SaaS security.
