How To Protect Against Identity Threats

Identity-based attacks have become a significant threat to individuals and organizations alike. In more than one-third of the ransomware attacks observed by the Secureworks® Incident Response team, identities are exploited as the initial access vector. The increasing digitalization of services and the proliferation of online accounts have created more opportunities for attackers to exploit. Additionally, the widespread use of remote work and the popularization of software-as-a-service (SaaS) identity and access management (IAM) solutions make it easier for cybercriminals to target individuals and organizations. These attacks, which target personal and organizational identities, can lead to severe consequences, including financial loss, reputational damage, and unauthorized access to sensitive information. Below are some essential strategies to help you defend against these types of attacks.

Strategies to Defend Against Identity-Based Attacks
Identity-based attacks involve the unauthorized use of someone's identity to gain access to systems, networks, or data. Common types of identity-based attacks include:

  • Phishing: Deceptive emails or messages designed to trick individuals into revealing personal information.
  • Password Spraying: Using common passwords against a list of known or probable accounts.
  • Brute Force Attacks: Using multiple passwords against a target account.
  • Man-in-the-Middle (MitM) Attacks: Intercepting and altering communication between two parties to steal information.
  • Social Engineering: Manipulating individuals into divulging confidential information.

To defend against these types of attacks, organizations and individuals can use the following strategies:

  1. Strengthen Password Policies

    Move to a passphrase model requiring longer passwords, but with less complexity. This makes it easier for users to remember their passphrases and still means they are difficult to brute force. Check for known compromised passwords as well.

  2. Implement Multi-Factor Authentication (MFA)

    MFA adds an extra layer of security by requiring additional verification methods, such as a text message code or biometric scan, beyond just a password.

  3. Educate and Train Employees

    Conduct regular cybersecurity training sessions to educate employees about the latest threats and how to recognize phishing attempts and other social engineering tactics. Periodically run simulated phishing attacks to test employees' awareness and response to potential threats.

  4. Monitor and Detect Suspicious Activity

    Use an extended detection and response (XDR) platform to monitor for attacks. This can allow you to see identity-based attacks or compromises quickly so you can respond. Conduct regular audits of access logs and user activities to identify and respond to suspicious behavior promptly.

  5. Secure Personal Information

    Only share personal information when absolutely necessary and ensure that it is transmitted securely. Encrypt sensitive data both in transit and at rest to protect it from unauthorized access.

  6. Adopt Zero Trust Principles
    Implement a Zero Trust model where every access request is verified, regardless of whether it comes from inside or outside the network. Ensure that users have the minimum level of access necessary to perform their job functions, reducing the risk of unauthorized access.

In an era where identity-based attacks are becoming increasingly prevalent, it is crucial for individuals and organizations to adopt robust security measures. By understanding the nature of these attacks and implementing strategies such as strengthening password policies, educating employees, monitoring suspicious activity, securing personal information, and adopting Zero Trust principles, you can significantly reduce the risk of falling victim to these threats. Stay vigilant, stay informed, and always be prepared to adapt to the evolving threat landscape.
