Cybersecurity Insurance and Multi-Factor Authentication

Financial institutions are increasingly embracing cybersecurity insurance as an important aspect of their information security program. Cyber insurance can offer vital coverage to protect businesses from various technology-related risks. Data breach insurance, for example, helps companies respond if personally identifiable information gets lost or stolen from their computers—whether intentionally by a hacker or accidentally by an employee. Cyber liability insurance offers expanded protection to help businesses prepare for, respond to, and recover from cyberattacks.

As cybercrimes continue to intensify, more cybersecurity insurance companies are calling for organizations to employ multi-factor authentication (MFA). Some carriers are even refusing to provide insurance quotes to companies that are not using this authentication method. From their perspective, MFA adoption makes perfect sense; it keeps unauthorized individuals from accessing sensitive information, reducing ransomware, data breaches, and other cyberattacks. This, in turn, minimizes insurance claims and saves carriers money.

For insurance providers, MFA is appealing because it lowers cyber risk by requiring users to verify who they are. The individual must furnish valid identification data followed by at least one other credential: a password, one-time passcode, or physical characteristics like their fingerprint or face. This strict authentication system allows organizations to certify people’s identity—before granting them access to sensitive information, an account, or other assets—and this can significantly strengthen their security.

While MFA is heavily promoted by many cyber insurance companies, an institution’s regulators may not require financial institutions to use multi-factor authentication. However, implementing MFA for a whole internal network may not be a simple task. Depending on the solution, it may require installing agent software to all the endpoints requiring MFA and configuring appropriate “break-glass” accounts for emergency use, which creates more infrastructure to be monitored and managed.

MFA Implementation Tips

To simplify MFA implementation, Banks and credit unions can apply a sequenced strategy instead of jumping straight to the internal network. As a first step, institutions can ensure MFA is turned on for all remote-access users, including creating endpoint control policies for their devices. The next logical step would be to lock down MFA for cloud applications. This includes Microsoft Online services like M365 (formerly Office 365) and Azure Active Directory (Azure AD). These solutions come with a variety of free security features that organizations can customize to their business requirements. Even at low licensing levels, these products allow MFA to be turned on for all users—which can be highly effective for averting business email compromise and ransomware attacks. But institutions will need higher-level licensing if they want to make conditional access policies based on the specific location, identity, or device of users. Azure AD Premium P1 and M365 Enterprise E3, for example, have a variety of advanced features that allow conditional access policies to be established to enhance security.

MFA is just one layer of security for banks and credit unions to consider. We hope this post provided some insight into applying MFA for both security and insurance purposes.

How Layered Security Can Address Growing Cyberthreats

With the increasing complexity of cyberattacks, financial institutions need to implement more effective—and comprehensive—security measures. They need a variety of elements to create a layered approach to secure their data, infrastructure, and other resources from potential cyberthreats.

Many organizations rely on a castle-and-moat network security model where everyone inside the network is trusted by default. (Think of the network as the castle and the network perimeter as the moat.) No one outside the network is able to access data on the inside, but everyone inside the network can. However, security gaps may still exist in this model and others. The best approach to compensate for gaps is to surround the network with layers of security.

The basic “table stakes” for a layered security approach include a perimeter firewall with content filtering, email threat filters, an endpoint malware solution, and a robust patch management process. Banks and credit unions could also invest in additional and more sophisticated layers but each one will have associated acquisition and management costs, along with ongoing maintenance. So, it’s prudent for institutions to invest only in the number of layers/solutions they can competently manage.

Key Concerns

Today the top IT security concern for many organizations is ransomware. Due to the proactive measures many financial institutions have taken, the banking industry has fewer security breaches than health care and some other industries thus far. However, when a breach does happen to a financial institution, the impact is more costly than breaches occurring in other industries.

Four-Layer Security Formula

With these concerns in mind, here’s a four-layer “recipe” organizations can employ to improve their security posture:

Training and Testing: Using email phishing tests can serve as a good foundation for minimizing BEC and other social engineering threats.
Network Design: Institutions should refresh older networks to segment their components into different zones. It’s no longer sufficient to have servers, workstations, and printers sitting in one IP space together.
Domain Name System (DNS) filtering: DNS filtering prevents potentially damaging traffic from ever reaching the network. Because it proactively blocks threats, this makes it one of the most effective and affordable security layers institutions can apply.
Endpoint Protection: Institutions should have this type of protection on each of their endpoints, and the best endpoint protection tools have built-in ransomware solutions.

Other Important Considerations

It’s important to back up data regularly and ensure that those backups are well beyond the reach of ransomware and other threats. (Backups done to a local server that’s on-site and are still on the network may be susceptible to ransomware.) One way to address this issue is to have immutable backups, which are backup files that can’t be altered in any way and can deploy to production servers immediately in case of ransomware attacks or other data loss. Another option is to send backups to a cloud solution like Microsoft Azure Storage, which is affordable and easy to integrate because there are no servers to manage.

Another crucial element in security is Transport Layer Security/Secure Sockets Layer (TLS/SSL) encryption protocol, which can be somewhat of a double-edged sword. About 80 percent of website traffic is encrypted to protect it from unauthorized users during transmission. Traditional firewalls don’t have the ability to scrutinize traffic against a content filtering engine, which means savvy hackers can hide ransomware and other dangerous content inside. But firewalls with advanced features are capable of TLS/SSL inspection; they can decrypt content, analyze it for threats, and then re-encrypt the traffic before entering or leaving the network.

There’s an array of security solutions that institutions can implement to establish layered protection against cyber threats. For more insights about this topic, listen to our webinar on “Cyber Threats, Why You Need a Layered Approach.”

Multi-Factor Authentication Offers Secure, Reliable Access Control

In our increasingly digital world, financial institutions must go beyond requiring only usernames and passwords for the sign-in process. They need to employ a combination of factors to validate the individuals using their resources, whether they’re customers accessing electronic products and services or employees accessing systems, applications, and data. Institutions can choose various levels of authentication to verify people’s identity before giving them access to sensitive information, accounts, and other assets. However, multi-factor authentication (MFA) offers a secure and reliable approach for reducing the potential for unauthorized access.

One of the key values of MFA lies in its use of multiple factors for the validation process. MFA adds a layer of protection by requiring users to present a variety of elements to prove who they are. With this method, users must supply valid identification data such as a username followed by at least two types of credentials, such as:

Something the person knows: This represents “secret” information that is known or shared by both the user and the authenticating entity. Passwords and personal identification numbers (PINs) are the most commonly used shared secrets, but newer methods of identification are gaining popularity. Users may be required to answer questions that only they should know, like the amount of their monthly mortgage payment. Another example is they might have to identify their pre-selected image (chosen when they opened their account) from a group of pictures.
Something the person has: This is often a security token or a physical device, such as an I.D. card or smartphone, that people must have in their possession. Password-generating tokens can significantly enhance security because they display a random, one-time password or passcode that the recipient must promptly provide to complete the authentication process. Having unpredictable, one-time passwords makes it more challenging for hackers to use keyboard logging to steal credentials.
Something the person is: This more complex approach to authentication uses a physical characteristic (biometrics) such as face, fingerprint, or voice recognition to verify people’s identity.

Since MFA incorporates factors based on knowledge, possession, and/or biometrics, it makes it more difficult for cybercriminals to compromise people’s identity. Thus, MFA is an ideal verification method to use when more sensitive or critical assets are at stake. MFA is so reliable that the Federal Financial Institution Examination Council (FFIEC) recommends applying it in more high-risk situations. “Management should use multi-factor authentication over encrypted network connections for administrators accessing and managing network devices,” states the FFIEC IT Handbook’s Architecture, Infrastructure, and Operations booklet.

MFA gives financial institutions a valuable security control for their internal and cloud resources. Take our quiz to see how much you know about multi-factor authentication.
