Penetration Testing for Law Firms

Law firms must stay prepared for security breaches as they are primary targets for cybercriminals. Regardless of size, firm livelihood is directly tied to protecting its sensitive information.Regularly scheduled penetration tests are a proactive way to identify and remedy security risks and prevent financial loss associated with cybersecurity breaches. Penetration tests determine systems’ susceptibility to digital security threats and often uncover weaknesses that firm members likely did not know existed. 

For many law firm clients, penetration testing is not only a friendly suggestion but also a requirement. Penetration tests help ensure adherence to compliance obligations mandated by regulations, including ABA and HIPAA accordingly. Moreover, if clients do not currently require penetration testing, it is good practice to regularly perform them to ensure systems are secure and current and future clients have assurance that sensitive data is protected. 

What Is Penetration Testing?

Penetration testing identifies weak points in systems by performing simulated cyberattacks. The goal is to identify insecure processes or operations, poor security settings and other weaknesses cyber criminals may exploit. Penetration testing examines perimeter defenses and weak security settings and requires high-level of expertise. Experts recommend annual testing by a neutral and qualified third-party, or more frequently by client request.

How Can a Firm Get the Most Out of Penetration Tests? 

Once a firm has decided to administer a penetration test, there are steps that will improve the outcomes and further strengthen system security. Here are 5 of the most important actions to consider:
1. Enlist a Third-Party to Administer the Test

While it’s possible for firms to perform tests on their own, penetration tests often produce the best results when they are conducted by a third-party partner. Partners have access to a variety of tools to perform the test and can determine which type of test is best based on the firm’s circumstances. Furthermore, a partner will delve deeper into the networks, systems, and applications than a less experienced security professional.

Effective third-party penetration testing partners will guide you through the testing process and provide and explain the reports and necessary next steps to improve security.

2. Scope the Test Properly

Thorough penetration tests will ensure the greatest number of vulnerabilities are found. Comprehensive tests are dependent upon proper scoping. Therefore, to ensure the test is properly scoped, consider all the devices and network elements in your firm’s system. This includes active hosts, Wi-Fi-enabled hardware and applications.

Comprehensive penetration tests will also involve an external and internal scan. External penetration testing targets the network perimeter and identifies defects on the Internet-facing systems. Internal penetration tests target the internal networks used by firm team members.

3. Prioritize Risks 

Once a report from the penetration test is generated, it should be used to determine the priority risks that need to be handled immediately and lower risk factors that can be addressed later.

4. Supplement Penetration Testing with Vulnerability Testing

The cousin of penetration testing is vulnerability testing, which involves scanning all networked devices for potential vulnerabilities. Vulnerability testing can be done automatically, more quickly, and at a lower cost. This type of test reports which vulnerabilities exist and if anything has changed since the last test. Vulnerability testing should also be completed on a regular basis, as often as once a week. The biggest difference is that penetration testing provides a more in-depth and detailed picture of potential risks. Both tests are vital, but penetration testing offers a proactive approach to cyberattack prevention, whereas vulnerability testing is a reactive mechanism.

5. Use the Test’s Findings to Develop or Improve Incident Response Plans

After remedying the vulnerabilities discovered in the penetration test, use those findings to further protect systems and data by reviewing them against your firm’s incident response plan.

Create response policies on how your firm should manage disruption if a bad actor exploits the vulnerabilities found in the testing. Once a threat is identified, the incident response plan should have recommendations on how to contain it. The plan should include instructions on how to eliminate threats and actions the firm must take to recover, including steps on restoring systems and communicating incidents to the appropriate stakeholders.

The time to start penetration testing is now. Continue tests on an annual basis with a trusted partner. In addition to reducing risks and potential costs associated with cyberattacks, a strong security perimeter is critical to firms’ public image and credibility. Clients, partners, shareholders, and staff expect that their firm’s sensitive data is always protected.
