The ISO in a Crisis: The Increased Importance of Vendor Management During a Pandemic

In a previous post, we discussed the role of the ISO in a pandemic and how he or she must make sure all routine tasks are still being completed; help the institution adapt to the new circumstances; and continue providing all products and services at an acceptable risk level.

While an institution may be prepared to continue business as usual, its third-party provider partners may not be on the same page. Like the bankers they support, third-party vendors are also experiencing the impact of the pandemic and are dealing with a variety of operational issues as well. Financial institutions must be able to perform effective vendor management during a crisis and develop alternative plans in the event a critical vendor may not be able to perform the services agreed upon.

Here are a few things the ISO must consider to effectively evaluate the institution’s vendors during a crisis like a pandemic:

Identify Vendor Risks

During a pandemic, the ISO must anticipate several different risk scenarios that can adversely impact the institution’s daily operations. With vendors, there are two interrelated key risk factors to consider:

“Supply chain risk” is related to the interconnectivity among the entity and others. In a pandemic, critical vendors may receive an overload of requests for products and services from a variety of industries and may not be able to keep up with demand. For example, many financial institution employees have been working remotely due to Coronavirus and to keep the network secure, financial institutions have provided company laptops to staff. However, if the FI’s laptop provider runs out of inventory, the institution is then put in a difficult situation – if they allow the use of personal devices, they must still make sure all employees can work safely from home and ensure the network remains secure.
“Cascading impact risk” is an incident affecting one entity or third-party service provider that then impacts other service providers, institutions, or sectors. For example, if the vendor that manages the bank’s perimeter security has a large case of absenteeism and an inadequate succession plan, real-time alerting may be negatively impacted, and the institution could be exposed.

Evaluating these risks with third-party vendors in advance will help ensure that they have the proper personnel redundancies in place, so these situations don’t impact the institution.

Managing Third-Party Risks

According to the Federal Financial Institution Examination Council (FFIEC), open communication and coordination with third parties, including critical service providers, is an important aspect of pandemic planning. A current SOC 2 report that covers the “availability” trust criteria is the best way to determine if the vendor has the capability to respond and recover its systems. In the absence of a SOC report, the first thing the ISO should request is a copy of the business continuity plan. Since the SOC report may not cover the service providers’ vendors (also referred to as sub-service providers), the ISO will also want to gain some awareness of the possibility of supply-chain risk. For example, how might a provider failure two to three layers deep affect the institution?

In addition to vendor business continuity plans, the ISO should ask additional questions about how the vendor is managing the pandemic. Here are a few examples:

When was the last time you updated and tested your BCM plan? Have you incorporated the possibility of a failure of a critical sub-service provider?
Is the likelihood and impact of a pandemic evaluated as a part of your risk assessment?
How do you plan to continue providing services in the event of the loss of key employees?
Have you been in communication with your critical third-party providers?
Are you financially prepared to withstand a long-term pandemic event?

Critical third parties are often either overlooked or under-managed during normal circumstances, but because of the current high level of interdependency among financial institutions and their third-parties, operational events such as pandemics call for much closer scrutiny. Depending on responses received, ISOs may choose to accelerate their oversight efforts, revisit their vendor risk assessments, and make adjustments accordingly.

Combating Business Email Compromise and Protecting Your Remote Workforce

Over the last two months, there have been more people working remotely than ever before, and with more being done outside the branch, financial institutions cannot rely on their usual firewall and anti-malware solutions to protect their staff. Today, the single most common attack used to target remote users is what is known as “business email compromise” (BEC).

Safe Systems hosted a live webinar earlier this month discussing how BEC works; the main techniques used in these types of attacks; and the cost-effective solutions needed to mitigate them. In case you missed it, here are a few key points from the webinar:

What is business email compromise and how does it work?

Business email compromise is a security exploit where an attacker targets an employee who has access to company funds or other non-public information and convinces the victim to transfer money into a bank account controlled by the attacker.

These attacks have two main categories:

Phishing emails – this is just a spoofed email that seemingly comes from someone you trust within the organization (like the CFO or CEO) instructing an employee to wire money to a specific account.
Account takeover – the attacker procures your real username and password and then logs into your mailbox where they are then able to send and receive emails at will from your actual account.

Using these attack methods, cybercriminals can commit many different types of fraud, including wire fraud, non-public information (NPI) theft, and spreading of malware.

There are also a number of different attack “types” that cybercriminals commonly use to take over accounts:

A single-stage attack is a social engineering email directing a user to complete a certain action. For example, an email may include a link that leads to a rogue website where the attacker is trying to capture login information. This is a fairly simple, one-step attack.

The more sophisticated variation on this type of attack is the multi-stage method. In this attack, we often see that instead of having a link in the email that goes to a suspicious website that could potentially be blocked by other security layers, attackers use a link in the email that goes to a highly trusted place like a Citrix share file or some other trusted site. If the user clicks the link, they’ve now stepped outside of any email security layers the institution might have in place. Most often these sites are SSL encrypted so this underscores the importance of having SSL inspection performed on your traffic to ensure links in emails do lead to legitimate, secure websites. The problem with this, however, is that it can be an increasingly difficult job for some financial institutions to implement and manage.

How Can Financial Institutions Defend Against These Threats?

Prevent

The first line of defense against business email compromise is to stop the user from being exposed in the first place, and the single most effective measure financial institutions can implement is user training. It’s important for financial institutions to regularly conduct penetration testing and use security awareness training to educate their employees. Over the years, we’ve seen a distinct correlation between the frequency of user security awareness training and the success rate of phishing attacks. Some institutions leverage self-testing tools such as KnowBe4, but there are many other services that financial institutions can use to test their employees.

Mitigate

The second line of defense is to stop the user from causing damage. To mitigate the threat, financial institutions can use a variety of effective tools, including:

Email Filtering – a tool that filters out suspicious emails to ensure no spam, malicious content, or sensitive data makes it out of the institution unauthorized.
DNS Filtering – is the process of using the Domain Name System lookup to find the IP address of a website to block malicious websites and filter out harmful or inappropriate content.
URL Rewrite – if an email has a link, the system rewrites the destination of the link to go to a security company first before the real session is connected.
Multifactor Authentication – this tool requires more than one method of authentication to verify a user’s identity for a login or other transaction. The methods include something you know (pin); something you have (phone) and/or something you are (biometrics).

These are just a few of the tools that can help strengthen your institution’s security posture and ensure users do not fall victim to malicious attacks. However, if they do, it is critical to have a plan to respond.

Respond

The last line of defense is to stop the expansion of damages if a threat has occurred. In this case, financial institutions must conduct an investigation into the cyberattack and have thorough logs of their mail system to understand exactly what occurred; how far it has spread; and determine the next steps. Community banks and credit unions should have an incident response plan in place and perform regular tabletop testing to confirm the plan works and will be useful when a real attack occurs.

Building a Pandemic Response Plan: What Are the Requirements for Community Banks and Credit Unions?

Building a Pandemic Response Plan

As COVID-19 continues to spread around the world, financial institutions have been forced to respond to this pandemic in new and innovative ways to stop the spread of the virus; protect their employees and the public; and keep their doors open and operations running smoothly to serve their customers and members. Community banks and credit unions are referencing the Pandemic sections of their business continuity management plans to determine the best way forward for their institutions during this challenging time. With the Federal Financial Institution Examination Council’s (FFIEC) recent business continuity management (BCM) guidance, many financial institutions are first of all wondering what has changed in the guidance, and second what specific additional changes this particular event might require.

Pandemic Planning

Since 2007, financial institutions were required to have a separate pandemic plan, and regulators only looked for documentation that institutions were testing their plans periodically. Unfortunately, the pandemic section of the business continuity plan (BCP) has tended to be treated as more of an afterthought since these situations have historically occurred much less often than natural disasters or other business interruptions. If they were assessed at all, they fell into the category of a high impact, low probability event.

Notwithstanding COVID-19, pandemics are still low probability events, but the impact of these events may be far more significant than past risk assessments have indicated. In what may now be perceived as an untimely move, the FFIEC made the decision in the 2019 BCM update to deemphasize Pandemic by categorizing it the same as any other disruptive event. The FFIEC no longer requires financial institutions to have a separate pandemic plan, but instead expects community banks and credit unions to assess and manage pandemic risk alongside all other possible disasters.

In other words, your BCM plan is your pandemic plan, and you must analyze the impact a pandemic can have on your organization; determine recovery time objectives (RTOs); and build out a recovery plan. You must also include a methodology to determine the key triggers your organization will use to activate your recovery plan when faced with a pandemic. But when should you activate your recovery plan and who is in charge of this process?

Pandemic Response

Before a recovery plan is activated, it is important to have an initial response team (typically comprised of C-Level executives) evaluate the situation and assess the potential impact of the current event on the institution. The team must determine if the situation is likely to negatively impact the institution’s ability to provide products and services to their customers or members beyond the established recovery time objectives outlined in the BCM plan.

The same rules apply in a pandemic. Community financial institutions should use the six pandemic phases outlined by the World Health Organization (WHO) or the Center for Disease Control (CDC) to evaluate the severity of the situation.

In most cases, the pandemic portion of the plan is not triggered for activation until phases 4-5 (or if between 20-40% of your workforce is not available to work).

What Regulators Expect

During a pandemic, regulators expect financial institutions to continue offering products and services to customers/members and conduct operations as normally as possible. This underscores the importance of including succession planning and cross training in the BCM plan. In the past, assumptions used to simulate a pandemic were that phases 4-5 wouldn’t last more than a week or two, so most financial institutions may only have planned for one person to be identified and pre-trained to step into a critical role until the event was over. However, the COVID-19 pandemic is a global crisis currently impacting at least 183 countries and territories and is predicted to impact many more people, and take much more time to contain.

To ensure critical functions continue, financial institutions should have at least two or three alternate staff members trained for every primary resource within the institution and assess whether some roles can be performed remotely. This can be difficult for smaller institutions with limited staff and resources. For specialized functions dominated by key personnel, such as funds management, wire services, human resources, etc., these institutions may not have multiple alternatives to step in if key employees are unavailable. In these circumstances, you may need to have other cross-trained staff members identified who can step into these roles quickly.

Next Steps: Lessons Learned

There will be many more lessons learned after the COVID-19 pandemic has passed, and regulators will expect those lessons to be reflected in your plan. When all is said and done, regulators are likely to ask “what have you learned from this event, and what have you done to enhance your pandemic plan based on those lessons learned?” Prior to this event, had you analyzed your business processes and their interdependencies, and prioritized them by recovery time? Since interdependencies include employees, and pandemic events almost exclusively impact personnel, have you identified employees with job duties capable of being performed remotely? If so, did they have secure, reliable, remote access? If those job duties are highly specialized, or highly critical, did you have alternate personnel identified and pre-trained to step in when needed?

The answers to these questions, and many more, will be used to enhance the pandemic section of your BCM plans, but until we reach that post-event, lessons-learned point, it’s important for financial institutions to continue to reference their business continuity plans; document the entire process; keep stakeholders informed; and put measures in place to continue serving their customers and members and protecting their employees and the public.
