Managing IT and data risk is a challenging job. When we outsource our IT, applications and data processing to third-parties more and more every day, managing that risk becomes almost impossible. No longer are our data and systems contained within an infrastructure that we have full control over. We now give vendors our data, and allow them to conduct operations on our behalf. 

The problem is, we don’t control their infrastructure, and we can never fully look under the hood to understand and vet their ability to protect our data and operations. We have to fully understand how important this issue is, and ensure we have the right governance, processes and teams to identify and mitigate any risks found in our vendors. No longer are our data and systems contained within an infrastructure that we have full control over

Today, everything is connected. Our own networks have Internet of Things (IoT) devices. We have VPN connections coming in, and we aren’t always sure who is on the other end of that connection. It is a full-time job just to get a handle on our own risk. How much harder, and how much larger should our teams and budgets be, to truly know and trust that our vendors can secure those devices and external connections? 

For every device and application we have internally, it is very difficult to even keep an accurate inventory. Do all of our vendors have some special sauce that allows them to overcome the traditional challenges of securing internal and vendor-connected networks? They are doing the same thing we are – doing our best with the limited human and financial resources allocated by our organization.

Risk Stratification And Control Objectives 

The benefits of outsourcing operations or using a vendor web application are clear. So how can we properly vet those vendors from an IT risk perspective? 

The very first thing we need to put in place is Risk Stratification. Risk Stratification presents a few targeted questions in the purchasing process. These questions include – what type of data will be shared? How much of this data? Will the data be hosted by a vendor? Will this hosting be in the US or offshored?  Has the vendor ever had a data breach? These questions allow you to quickly discern if a risk assessment is needed and if so, what depth and breadth.  Risk stratification allows you to make decisions that not only improve your team’s efficiency, but also ensure that you are not being a roadblock to the business

Risk stratification allows you to make decisions that not only improve your team’s efficiency, but also ensure that you are not being a roadblock to the business. With risk stratification, you can justify the extra time needed to properly assess a vendor’s security. 

And in the assessment of a vendor’s security, we have to consider what control objectives we will use. Control objectives are access controls, policies, encryption, etc. In healthcare, we often use the HITRUST set of control objectives. In assessing against those control objectives, we usually use a spreadsheet. 

Today, there are many vendors who will sell us more automated ways to get that risk assessment completed, without passing spreadsheets back and forth. These solutions are great if you can get the additional budget approved. 

Multi-Factor Authentication 

Even if we are using old-fashioned spreadsheets, we can ensure that the questions asked of the vendor include a data flow and network/security architecture document. We want to see the SOC2 report if they are hosting their solution in Amazon, etc. If they are hosting it within their own datacentre, we absolutely want to see a SOC2 Type II report. If they haven’t done that due diligence, should that be a risk for you? 

Today, we really need to be requiring our vendors to have multi-factor authentication on both their Internet-facing access, as well as their privileged internal access to our sensitive data. I rate those vendors who do not have this control in place as a high risk. We’ve recently seen breaches that were able to happen because the company did not require administrators or DBAs to use a 2-factor authentication into sensitive customer data sources.

This situation brings up the issue of risk acceptance. Who in your organization can accept a high risk? Are you simply doing qualitative risk assessment – high, medium and low risks? Or are you doing true quantitative risk analysis? The latter involves actually quantifying those risks in terms of likelihood and impact of a risk manifesting, and the dollar amount that could impact your organization.  

So is it a million dollars of risk? Who can accept that level of risk? Just the CEO? These are questions we need to entertain in our risk management programs, and socialised within your organization. 

This issue is so important – once we institute risk acceptance, our organization suddenly starts caring about the vendors and applications we’re looking to engage. If they are asked to accept a risk without some sort of mitigation, they suddenly care and think about that when they are vetting future outsourced solutions.Quantitative risk analysis involves quantifying risks in terms of likelihood and impact of a risk manifesting

Risk management process 

In this discussion, it is important to understand how we think of, and present, the gaps we identify in our risk management processes. A gap is not a risk.  If I leave my front door unlocked, is that a control gap or a risk? It is a gap – an unlocked door. What is the risk? 

The risk is the loss of property due to a burglary or the loss of life due to a violent criminal who got in because the door was unlocked. When we present risks, we can’t say the vendor doesn’t encrypt data. The risk of the lack of encryption is fines, loss of reputation, etc. due to the breach of data. A gap is not a risk.

Once we’ve conducted our risk analysis, we must then ensure that our contracts protect our organization? If we’re in healthcare, we must determine if the vendor is, in fact, a true HIPAA Business Associate, and if so we get a Business Associate Agreement (BAA) in place. I also require my organization to attach an IT Security Amendment to these contracts. The IT Security Amendment spells out those control objectives, and requires each vendor to sign off on those critical controls.  We are responsible for protecting our organization’s IT and data infrastructure – today that often means assessing a 3rd-party’s security controls

One final note on risk assessments – we need to tier our vendors. We tier them in different ways – in healthcare a Tier 1 vendor is a vendor who will have our patient information on the Internet. Tiering allows us to subject our vendors to re-assessment. A tier 1 vendor should be re-assessed annually, and may require an actual onsite assessment vs. a desk audit. A tier 2 vendor is re-assessed every 2 years, etc.

We are responsible for protecting our organization’s IT and data infrastructure – today that often means assessing a 3rd-party’s security controls. We must be able to fully assess our vendors while not getting in the way of the business, which needs to ensure proper operations, financial productivity and customer satisfaction. If we truly understand our challenge of vendor risk management, we can tailor our operations to assess at the level needed, identify and report on risks, and follow-up on any risks that needed mitigated.

What New Technologies And Trends Will Shape Video Analytics?
What New Technologies And Trends Will Shape Video Analytics?

The topic of video analytics has been talked and written about for decades, and yet is still one of the cutting-edge themes in the physical security industry. Some say yesterday’s analytics systems tended to overpromise and underdeliver, and there are still some skeptics. However, newer technologies such as artificial intelligence (AI) are reinvigorating the sector and enabling it to finally live up to its promise. We asked this week’s Expert Panel Roundtable: What new technologies and trends will shape video analytics in 2021?

Tackling The Challenge Of The Growing Cybersecurity Gap
Tackling The Challenge Of The Growing Cybersecurity Gap

The SolarWinds cyberattack of 2020 was cited by security experts as “one of the potentially largest penetrations of Western governments” since the Cold War. This attack put cybersecurity front and center on people’s minds again. Hacking communication protocol The attack targeted the US government and reportedly compromised the treasury and commerce departments and Homeland Security. What’s interesting about the SolarWinds attack is that it was caused by the exploitation of a hacker who injected a backdoor communications protocol.  This means that months ahead of the attack, hackers broke into SolarWinds systems and added malicious code into the company’s software development system. Later on, updates being pushed out included the malicious code, creating a backdoor communication for the hackers to use. Once a body is hacked, access can be gained to many. An explosion of network devices What has made the threat of cyberattacks much more prominent these days has been IT's growth in the last 20 years, notably cheaper and cheaper IoT devices. This has led to an explosion of network devices. IT spending has never really matched the pace of hardware and software growth Compounding this issue is that IT spending has never really matched the pace of hardware and software growth. Inevitably, leading to vulnerabilities, limited IT resources, and an increase in IoT devices get more attention from would-be hackers. Bridging the cybersecurity gap In the author’s view, this is the main reason why the cybersecurity gap is growing. This is because it inevitably boils down to counter-strike versus counter-strike. IT teams plug holes, and hackers find new ones, that is never going to stop. The companies must continue fighting cyber threats by developing new ways of protecting through in-house testing, security best practice sources, and both market and customer leads. End-user awareness One of the key battlegrounds here is the education of end-users. This is an area where the battle is being won at present, in the author’s opinion. End-users awareness of cybersecurity is increasing. It is crucial to educate end-users on what IoT devices are available, how they are configured, how to enable it effectively, and critically, how to use it correctly and safely.

Will Airport Security’s Pandemic Measures Lead To Permanent Changes?
Will Airport Security’s Pandemic Measures Lead To Permanent Changes?

Travel volumes at airports have been increasing of late, although still below the 2.5 million or so passengers the Transportation Security Administration (TSA) screened every day, on average, before the pandemic. As passengers return, they will notice the airport security experience has changed during the pandemic – and many of the changes are likely to continue even longer. Need for touchless technology The lowest U.S. air travel volume in history was recorded last April, with approximately 87,500 passengers. As passenger traffic plummeted, the aviation community sought to explore the potential of new technologies to make security checkpoints more contactless and flexible when the traffic numbers return. The pandemic has seen an increase in touchless technology deployed in the screening area. Used for cabin baggage screening, Computed Tomography (CT) produces high-quality, 3-D images to enable a more thorough analysis of a bag’s contents. Imaging Technology Millimeter-wave body scanners began replacing metal detectors globally as a primary screening method Enhanced Advanced Imaging Technology (eAIT), which uses non-ionizing radio-frequency energy in the millimeter spectrum, safely screens passengers without physical contact for threats such as weapons and explosives, which may be hidden under a passenger’s clothing. Millimeter-wave body scanners began replacing metal detectors globally as a primary screening method.  AI algorithms Other innovations include an automatic screening lane, centralized image processing, and artificial intelligence (AI). Looking ahead, AI algorithms have the ability to clear most passengers and bags automatically, making the process smoother and freeing up staff to focus only on alarms. The pandemic’s need for contactless screening may accelerate the adoption of AI.   CAT machine Credential Authentication Technology (CAT) machines automatically verify identification documents presented by passengers during the screening process. The TSA continues to accept expired Driver’s Licenses and state-issued IDs for up to a year after expiration, based on the premise that license renewals may be delayed and/or more difficult during the pandemic. The REAL ID enforcement deadline was extended to Oct. 1, 2021.  Health precautions Checkpoint health precautions have been a part of the airport screening experience since early in the pandemic. Last summer, the TSA announced the “Stay Healthy. Stay Secure” campaign, which included requirements such as social distancing among travelers, ID verification without physical contact, plastic shielding installed at various locations, and increased cleaning and disinfecting. In January 2021, President Biden signed an Executive Order requiring travelers to wear face masks when in airports and other transportation facilities (to remain in effect until May 11). Checkpoint screening Clear is a privately owned company that provides expedited security that uses biometrics either a person’s eyes or face to speed along the process of getting people through checkpoints. TSA officers wear masks and gloves at checkpoints and may also wear eye protection or clear plastic face shields. The limits on allowable liquids a passenger may take on board were broadened to include a hand sanitizer container of up to 12 ounces, one per passenger in a carry-on bag. a paradigm shift Just as aviation security changed after 9/11, the COVID-19 crisis is expected to lead to a paradigm shift to create a safer and more secure environment. Measures were implemented so that passengers, staff and other stakeholders could have continued assurance and confidence in airports amid and after the pandemic.
