How to Develop an Effective Cybersecurity Incident Response Plan for Businesses

Data breaches have become more frequent and costly than ever. In 2021, the average data breach cost companies more than $4 million. Threat actors are increasingly likely to be sophisticated. The emergence of ransomware-as-a-service (RaaS) has allowed even unsophisticated, inexperienced parties to execute harmful, disruptive, costly attacks. In this atmosphere, what can businesses do to best prepare for a cybersecurity incident?

One fundamental aspect of preparation is to develop a cyber incident response plan (IRP). The National Institute of Standards and Technology (NIST) identified five basic cybersecurity functions to manage cybersecurity risk:

  • Identify
  • Protect
  • Detect
  • Respond
  • Recover

In the NIST framework, anticipatory response planning is considered part of the “respond” function, indicating how integral proper planning is to an effective response. Indeed, NIST notes that “investments in planning and exercises support timely response and recovery actions, resulting in reduced impact to the delivery of services.”

But what makes an effective IRP? And what else goes into quality response planning?

A proper IRP requires several considerations. The primary elements include:

  • Assigning accountability: identify an incident response team
  • Securing assistance: identify key external vendors including forensic, legal and insurance
  • Introducing predictability: standardize crucial response, remediation and recovery steps
  • Creating readiness: identify legal obligations and information to facilitate the company’s fulfillment of those obligations
  • Mandating experience: develop periodic training, testing and review requirements

After developing an IRP, a business must ensure it remains current and effective through regular reviews at least annually or anytime the business undergoes a material change that could alter either the IRP’s operation or the cohesion of the incident response team leading those operations.

An effective IRP is one of several integrated tools that can strengthen your business’s data security prior to an attack, facilitate an effective response to any attack, speed your company’s recovery from an attack and help shield it from legal exposure in the event of follow-on litigation.

Governor Wolf Signs Act 151 Addressing Data Breaches Within Local Entities

On Thursday, November 3, 2022, Governor Tom Wolf signed PA Senate Bill 696, also known as Act 151 of 2022 or the Breach of Personal Information Notification Act.  Act 151 amends Pennsylvania’s existing Breach of Personal Information Notification Act, strengthening protections for consumers, and imposing stricter requirements for state agencies, state agency contractors, political subdivisions, and certain individuals or businesses doing business in the Commonwealth.  Act 151 expands the definition of “personal information,” and requires Commonwealth entities to implement specific notification procedures in the event that a Commonwealth resident’s unencrypted and unredacted personal information has been, or is reasonably believed to have been, accessed and acquired by an unauthorized person.  The requirements for state-level and local entities differ slightly; this Alert will address the impact of Act 151 on local entities.  While this law does not take effect until May 22, 2023, it is critical that all entities impacted by this law be aware of these changes.

For the purposes of Act 151, the term “local entities” includes municipalities, counties, and public schools.  The term “public school” encompasses all school districts, charter schools, intermediate units, cyber charter schools, and area career and technical schools.  Act 151 requires that, in the event of a security breach of the system used by a local entity to maintain, store, or manage computerized data that includes personal information, the local entity must notify affected individuals within seven business days of the determination of the breach.  In addition, local entities must notify the local district attorney of the breach within three business days.

The definition of “personal information” has been updated, and includes a combination of (1) an individual’s first name or first initial and last name, and (2) one or more of the following items, if unencrypted and unredacted:

  • Social Security number;
  • Driver’s license number;
  • Financial account numbers or credit or debit card numbers, combined with any required security code or password;
  • Medical information;
  • Health insurance information; or
  • A username or password in combination with a password or security question and answer.

The last three items were added by this amendment.  Additionally, the new language provides that “personal information” does not include information that is made publicly available from government records or widely distributed media.

Act 151 defines previously undefined terms, drawing a distinction between “determination” and “discovery” of a breach, and setting forth different obligations relating to each.  “Determination,” under the act, is defined as, “a verification or reasonable certainty that a breach of the security of the system has occurred.”  “Discovery” is defined as, “the knowledge of or reasonable suspicion that a breach of the security of the system has occurred.”  This distinction affords entities the ability to investigate a potential breach before the more onerous notification requirements are triggered.  A local entity’s obligation to notify Commonwealth residents is triggered when the entity has reached a determination that a breach has occurred.  Further, any vendor that maintains, stores, or manages computerized data on behalf of a local entity is responsible for notifying the local entity upon discovery of a breach, but the local entity is ultimately responsible for making the determinations and discharging any remaining duties under Act 151.

Another significant update afforded by Act 151 is the addition of an electronic notification procedure.  Previously, notice could be given: (1) by written letter mailed to the last known home address of the individual; (2) telephonically, if certain requirements are met; (3) by email if a prior business relationship exists and the entity has a valid email address; or (4) by substitute notice if the cost of providing notice would exceed $100,000, the affected class of individuals to be notified exceeds 175,000, or the entity does not have sufficient contact information.  Now, in addition to the email option, entities can provide an electronic notice that directs the individual whose personal information may have been materially compromised to promptly change their password and security question or answer, or to take any other appropriate steps to protect their information.

Act 151 also provides that all entities that maintain, store, or manage computerized personal information on behalf of the Commonwealth must utilize encryption –  this provision originally applied only to employees and contractors of Commonwealth agencies, but was broadened in Act 151.  Further, the act provides that all entities that maintain, store, or manage computerized personal information on behalf of the Commonwealth must maintain policies relating to the transmission and storage of personal information – such policies were previously developed by the Governor’s Office of Administration.

Finally, under Act 151, any entity that is subject to and in compliance with certain healthcare and federal privacy laws is deemed to be in compliance with Act 151.  For example, an entity that is subject to and in compliance with the Health Insurance Portability and Accountability Act of 1996 (HIPAA) is deemed compliant with Act 151.

Although Act 151 is an amendment to prior legislation, the updates create potential exposure for local entities and the vendors that serve them.  For local municipalities, schools, and counties, compliance will require a proactive approach – local entities will have to familiarize themselves with the new requirements, be mindful of the personal information they hold, and ensure that their vendors are aware of their obligations.  Further, local entities will be required to implement encryption protocols, and prepare and maintain storage and transmission policies.

Law Firm Data Breaches: Big Law, Big Data, Big Problem

law firm data breachesThe Year of the Breach

2016 was the year that law firm data breaches landed and stayed squarely in both the national and international headlines. There have been numerous law firm data breaches involving incidents ranging from lost or stolen laptops and other portable media to deep intrusions exposing everything in the law firm’s network. In March, the FBI issued a warning that a cybercrime insider-trading scheme was targeting international law firms to gain non-public information to be used for financial gain. In April, perhaps the largest volume data breach of all time involved law firm Mossack Fonesca in Panama. Millions of documents and terabytes of leaked data aired the (dirty) laundry of dozens of companies, celebrities and global leaders. Finally, Chicago law firm, Johnson & Bell Ltd., was in the news in December when a proposed class action accusing them of failing to protect client data was unsealed.

A Duty to Safeguard

Law firms are warehouses of client information and how that information is protected is being increasingly regulated and scrutinized. The legal ethics rules require attorneys to take competent and reasonable measures to safeguard information relating to client. (ABA Model Rules 1.1, 1.6 and Comments). Attorneys also have contractual and regulatory obligations to protect information relating to clients and other personally identifiable information, financial and health, for example.

American Bar Association’s 2016 TechReport

Annually, the ABA conducts a Legal Technology Survey (Survey) to gauge the state of our industry vis-à-vis technology and data security. The Survey revealed that the largest firms (500 or more attorneys) reported experiencing the most security breaches, with 26% of respondents admitting they had experienced some type of breach. This is a generally upward trend from past years and analysts expect this number only to rise. This is likely because larger firms have more people, more technology and more data so there is a greater exposure surface and many more risk touch-points.

Consequences of Breach

The most serious consequence of a law firm security breach is loss or unauthorized access to sensitive client data. However, the Survey shows there was a low incidence of this, only about 2% of breaches overall resulted in loss of client data. Other concerning consequences of the breaches are significant though. 37% reported business downtime/loss of billable hours, 28% reported hefty fees for correction including consulting fees, 22% reported costs associated with having to replace hardware/software, and 14% reported loss of important files and information.

Employing & Increasing Safeguards Commonly Used in other Industries

The 2016 Survey shows that while many law firms are employing some safeguards and generally increasing and diversifying their use of those safeguards, our industry may not be using common security measures that other industries employ.

1. Programs and Policies. The first step of any organization in protecting its data is establishing a comprehensive data security program. Security programs should include measures to prevent breaches (like policies that regulate the use of technology) and measures to identify, protect, detect, respond to and recover from data breaches and security incidents. Any program should designate an individual, like a full-time privacy officer or information security director, who is responsible for coordinating security. However, the numbers show that the legal industry may not be up to speed on this basic need. Survey respondents reported their firms had the following documented policies:

Document or records management and retention policy: 56%

Email use policy: 49%

Internet use/computer use policy: 41%

Social media use: 34%

2. Assessments. Using security assessments conducted by independent third parties has been a growing security practice for other industries; however, law firms have been slow to adopt this security tool, with only 18% of law firms overall reporting that they had a full assessment.

3. Standards/Frameworks. Other industries use security standards and frameworks, like those published by the International Organization for Standardization (ISO) to provide approaches to information security programs or to seek formal security certification from one of these bodies. Overall, only 5% of law firms reported that they have received such a certification.

4. Encryption. Security professionals view encryption as a basic safeguard that should be widely deployed and it is increasingly being required by law for any personal information; however only 38% of overall respondents reported use of file encryption and only 15% use drive encryption. Email encryption has become inexpensive for businesses and easier to use with commercial email services yet overall only 26% of respondents reported using email encryption with confidential/privileged communications or documents sent to clients.

5. Cybersecurity Insurance. Many general liability and malpractice polices do not cover security incidents or data breaches, thus there is an increasing need for business to supplement their coverage with cybersecurity insurance. Unfortunately, only 17% of attorneys reported that they have cyber coverage.

Conclusion

It is important to note that the figures revealed by the 2016 Survey, while dismaying, may also be extremely conservative as law firms have a vested interest in keeping a breach of their client’s data as quiet as possible. There is also the very real possibility that many firms don’t yet know that they have been breached. The 2016 Survey demonstrates that there is still a lot of room for improvement in the privacy and data security space for law firms. As law firms continue to make the news for these types of incidents it is likely that improvement will come sooner rather than later.
