Responding to Cybersecurity Threats: How to Assess Your Tools and Cyber Strategy
Cybersecurity is in crisis. Cybersecurity threats are becoming increasingly sophisticated and pervasive. Bad actors have access to all the latest technology and tools, including artificial intelligence, for free or very little cost. They have endless time and resources to send out millions of cyberattacks – and need only a single successful attack to reap a windfall. It’s asymmetric warfare, and the attackers’ tools just keep improving.
In response, dozens of new cybersecurity providers seem to enter the market every day. Artificial intelligence, new tools and easy access to information mean that innovation keeps accelerating daily. With cybersecurity threats regularly making headlines, and pressure on companies to secure their data (and customers’ data) growing, new cybersecurity providers barely need to advertise to gain customers’ attention. For the same reasons, venture capitalists are eager to fund cybersecurity firms. The traditional big players in the market are rushing to upgrade their outdated packages. It’s a noisy marketplace, and companies trying to protect their data and systems are confused about how best to do so.
How Companies Are Addressing Cybersecurity Threats
Companies have responded to the crowded cybersecurity marketplace in different ways. Some just bury their heads in the sand, deciding to deal with incursions when they occur, or to hope that they’re too small to be worth targeting with a cyberattack. Others are spending way too much money on cybersecurity, experimenting with every new product that hits the market.
Many companies believe that they already have all the tools they need to combat cybersecurity threats, but haven’t properly patched their existing systems, which need regular updates to combat ever-changing cyber threats. On top of that, many companies experience dozens of little attacks every day, from all sides, and it’s hard to know where to put resources.
But burying your head in the sand or sticking with old tools that don’t counteract today’s cybersecurity threats is simply not an option. And throwing money at whatever strikes a chord isn’t an effective strategy, either.
What Is an Effective Strategy for Managing Cybersecurity Threats?
Resolving the cybersecurity crisis starts with an honest cyber vulnerability assessment, either by your internal experts or by outside experts.
Ultimately, this cyber vulnerability assessment should give you a map of where your company is in terms of cybersecurity. Next, you’ll need a map of where you’re going. Your experts should prepare a plan that:
- Closes your cybersecurity gaps over time
- Analyzes the financial risks of not closing gaps and prioritizes closing the gaps that put the company at the most risk
- Includes a company cybersecurity policy that every employee is expected to follow (much like a dress code or conduct policy)
This cyber vulnerability assessment and plan give you a framework for cybersecurity decisions. Armed with an understanding of your risk profile, your budget, your weaknesses and the consequences of various breaches, your experts should be able to recommend cybersecurity investments that will provide the best ROI for your company. The key is to remain true to this framework, even as new cybersecurity threats rear their ugly heads. Certainly, you want to maintain some flexibility, with strategies adjusting as truly required. But stick with what you know to be important to your business, and let that lead your investment decisions.

To thwart cyber attacks, the traditional approach has been to focus on the perimeter to repel intruders. But over time the perimeter has become a sieve. Today’s hackers easily break through it or find ways around it. In fact, a new study by RiskIQ estimates the cost cybercrime at $856,000 per minute. AI cybersecurity solutions directly address these challenges, which is why many now view the technology as the future of cybersecurity.
Going Beyond the Perimeter Is the Future of Cybersecurity
Focusing on defending the perimeter has been akin to wearing a Hazmat suit in a hostile environment: Any small perforation, and you were doomed to unexpected consequences at the hands of hackers who had the time and intellect to play games with your critical assets.
Not only are perimeters fragile and the gap in available talent huge, but most IT teams are often so stretched for resources that they can’t keep up with the updates necessary to protect against the myriad attacks that can penetrate a company’s external defenses. WannaCry was just an example of that.
Over the years, computing speed has grown exponentially –multiplying more than 3,000x since 1991 – to the point where even a $5 Raspberry Pi can now run deep learning algorithms. So it’s not a surprise that, in recent years, focus has shifted to using AI cybersecurity to complement traditional defenses in many ways and neutralize stealthy, unknown threats that may have already breached the perimeter before any irreparable damage to network or data is done.
Applying Artificial Intelligence in Cybersecurity
In AI cybersecurity programs, which are now being embedded in companies’ networks, endpoints and data are evolving into immune systems that allow internal defenses to shorten the dwell-time and pre-empt the devastation that can follow a breach.
While there is no need to abandon the perimeter, today’s smart CISOs are squarely focused on increasing their AI-driven pre-emption capabilities and boosting their own auto-immune systems. Artificial intelligence in cybersecurity is by no means perfect yet, but cybercriminals are already using automation and machine learning 24x7x365. In the never-ending cat-and-mouse game, AI is slated to continue gaining ground to build predictive capabilities and strengthen defenses for the foreseeable future.

Recent headlines have been abuzz with ICS experts warning of grid vulnerability to hacking. Digital threat actors have become exceptionally skilled at infiltrating every type of computer network. Industrial Control Systems (ICS) are no different: While ICS networks were generally thought to be more secure due to not communicating outside of the corporate network or on the internet, attackers have managed to compromise them and steal valuable production data.
Some of the most effective tools for ICS cybersecurity are the emerging technologies in Machine Learning and Artificial Intelligence. By combining real-time data monitoring with orchestration and automated response, AI/ML solutions are proving their value when compared to legacy systems and human-intervention driven response times.
A Real-World Example of Using AI for ICS Network Security
At the last Black Hat Europe conference, security research firm CyberX demonstrated how data exfiltration was possible from a supposedly air-gapped ICS network. By delivering a payload of specific ladder logic code into Programmable Logic Controllers, the attack was programmed to send out copies of data through encoded radio signals which can be received by AM radios and analyzed by special-purpose software. As the communication channel is outside the TCP/IP stack, there is no encryption to safeguard the data once it’s captured.
How does AI respond to this threat? In this case, Machine Learning can be used to craft an algorithm which establishes a “normal” state and monitors traffic and configurations to compare against that state. This baseline can include network traffic, equipment settings, and even the source code of PLCs. With its continuous heartbeat checks, the algorithm can detect when the system deviates from the baseline and immediately alert security staff of the change.
Another real-world example involving operational technology security comes very recently from the ransomware attack on Atlanta’s municipal infrastructure, which involved encrypting city files, locking access to online services, and blocking the city from processing court cases and warrants. This is just the latest in a string of attacks on American cities. Previously, hackers gained access to Dallas’s tornado warning system and set off sirens in the middle of the night. In the case of Atlanta, an AI cybersecurity layer would have been able to spot irregularities in system access and lockdown channels before the hackers could manipulate the permissions.
AI and ICS Cybersecurity: Adding Value to Existing Systems
Where does AI fit into your existing ICS network security program? You already have the ICS equipment sectioned off on its own VLAN(s), firewalled, monitored, and protected by IDS/IPS, SIEMs, and other security tools. Where does it make sense to insert AI/ML into the equation?
The biggest advantage of implanting an AI solution for ICS cybersecurity is its real-time response and orchestration. AI tools don’t need to wait for security staff to make a decision. They don’t see a black and white picture of firewall rules which often miss malware traffic flying under the radar, masquerading as “normal” network signals. Machine algorithms can detect abnormal data exchanges and immediately respond to the threat, long before a SOC resource would be alerted. Some AI offerings can even monitor devices that don’t communicate over TCP/IP, creating powerful visibility into non-networked equipment.
A particularly interesting tool to protect industrial control systems is Cyberbit’s ScadaShield, a layered solution to provide full stack ICS networkdetection, visibility, smart analytics, forensics and response. ScadaShield performs continuous monitoring and detection across the entire attack surface for both IT and OT components and can be combined with SOC automation to trigger workflows that accelerate root cause identification and mitigation.
Large-scale processes operating at critical power generation, electrical transmission, water treatment, and refining sites, as well as major manufacturing plants are more at risk than ever. The good news is that new developments in Artificial Intelligence and Machine Learning have created new ways to protect these systems and improve ICS cybersecurity.
If you haven’t already done so, this is a good time to consider adding an AI/ML solution to your security perimeter to take your prevention and response times to the next level.

Machine learning and artificial intelligence have exploded onto the cybersecurity scene over the last year. Software vendors and MSSPs are scrambling to bring their particular flavor of AI cyber security to market and claim their stake as industry leaders.
While AI has quickly become table stakes for an effective security posture, some of it can also seem to be overhyped in some respects. In this post, we’ll aim to cut through the superlatives and provide a few thoughts on the role of artificial intelligence in cyber security.
Artificial Intelligence in Cyber Security Does Not Replace Traditional Tools
By claiming that AI will replace traditional tools while lowering labor costs and probably making coffee at the same time, some advertising has put AI on a pedestal that it may not have achieved yet.
Here are some things that AI cyber security definitely will not replace. Security teams will still need to keep around:
- Employee training and a security-sensitive culture
- Smart policies and processes
- Qualified architects, managers, engineers, and analysts
- Rock-solid, layered infrastructure with effective controls around it
If you find yourself saying, “Wait, that’s 95% of my security program,” you’re right. Artificial intelligence in cyber security is a complement to a well-run cyber framework, not a replacement for it.
Must-Ask Questions When Evaluating AI Cyber Security Tools
We all have seen that technology can be promoted with grand promises backed by sometimes disappointing results. To avoid a dud in your AI implementation, you may want to sit down with your security team and your vendor rep to go over a few questions:
- How do your AI algorithms actually work? How mature is the technology? What are its blind spots?
- How well does it avoid false positives and false negatives?
- How do you measure the incremental benefits and the expected ROI?
- What outside support are we going to need to implement and maintain this?
- How much additional training will we need to use this effectively?
- Does it produce usable reports that actually mean something?
- What results have your other clients seen from it?
- Does it outperform what I already have, or will it be just another software bloating up my network?
Pitfalls to Avoid When Implementing an AI Cyber Security Solution
Adding software to your organization’s toolkit is rarely a trivial matter, and even less so when you’re dealing with AI. Here are some potential mistakes when deploying an AI cyber security tool:
- Expecting a “set-and-forget” solution that will replace the whole security program: See the first section of this post.
- Thinking that an in-house developed solution will be best-in-show without exploring other available options.
- Expecting that the AI tool won’t require any customization or integration.
- And possibly the most delicate one: Thinking it’ll all work out on automatic pilot without specialized AI expertise on your team or assistance from AI safety experts.
The fact of the matter is that it is no longer viable to delay implementation of robust AI cyber security tools. Bad actors have already started using AI.
A talented cybersecurity team and company-wide awareness trainings go a long way. Artificial intelligence in cyber security simply brings a needed support structure that can assist your teams to prevent attacks and accelerate mitigation if needed. As businesses undergo the digital transformation, it is imperative they also leverage new developments in cyber capabilities.
