AI's ability to learn from historical data and adapt to new threats makes it a valuable asset in the ever-evolving landscape of cybersecurity.

Artificial intelligence (AI) is also being used in the prevention of cybersecurity attacks by enhancing the security and resilience of online systems and data. Some of the ways that AI can be used for this purpose are:

Password Protection and Authentication: AI can help users create and manage strong and unique passwords, as well as use biometric or behavioral factors to verify their identity. For example, some password managers use AI to generate and store passwords, while some platforms use AI to authenticate users based on their fingerprints, typing styles, or voice patterns.

Phishing Detection and Prevention: Artificial Intelligence can help users identify and avoid phishing attacks, which are one of the most common and effective ways of stealing credentials, data, or money from unsuspecting users. Currently, some email services use AI to filter out spam and phishing emails, while some browsers use AI to warn users of malicious websites.

Vulnerability Management and Patching: AI can help users discover and fix vulnerabilities in their systems and applications, as well as update them with the latest security patches. Security experts advise their clients to use AI to scan and monitor systems for potential weaknesses, while some software vendors use AI to automate the patching process.

Network Security and Firewall: Artificial Intelligence can help users protect their network and devices from unauthorized access or intrusion, as well as block or allow traffic based on predefined rules. For example, some routers use AI to optimize the network performance and security, while some firewalls use AI to analyze and filter network traffic.

AI can also strengthen the response capabilities of cybersecurity systems by enabling faster, smarter, and more effective actions to contain and mitigate cyberattacks. Some of the ways that AI can be used for this purpose are:

Automated Incident Response: Artificial Intelligence can help automate parts of the incident response process, such as identifying the root cause, isolating the affected systems, applying the appropriate remediation, and restoring normal operations. Did you know that some security tools use AI to orchestrate and execute predefined workflows and playbooks for common cyber scenarios.

Adaptive Threat Hunting: AI can help enhance the threat hunting capabilities of security teams, by providing them with actionable intelligence, recommendations, and insights. Some security platforms use AI to analyze and correlate data from various sources, such as network traffic, system logs, and threat intelligence feeds, and generate hypotheses and queries for security analysts to investigate.

Dynamic Risk Management: Artificial Intelligence can help improve the risk management strategies of organizations, by providing them with continuous and comprehensive visibility, assessment, and prioritization of their cyber risks. Today there exist security solutions that use AI to monitor and measure the security posture and performance of businesses and suggest the best actions and investments to reduce their exposure and impact.

Let’s now transition from talking about using artificial intelligence in the fight against cyber-attacks, to companies having robust cybersecurity plans.

Let me just say, companies should have a cybersecurity plan to protect their data, operations, and reputation from cyber threats. A cybersecurity plan can help prevent costly business disruptions, reduce the risk of ransomware attacks, and comply with legal and ethical obligations. Some of the steps to develop a cybersecurity plan include:

• Assessing the current state of security and identifying potential vulnerabilities.
• Establishing policies, procedures, and tools to prevent, detect, and respond to cyber incidents.
• Educating and training employees and stakeholders on cybersecurity best practices and responsibilities.
• Reviewing and updating the plan regularly to adapt to changing threats and technologies.

Cybersecurity is not a one-time project, but an ongoing process that requires constant vigilance and investment. Now let me focus on what the potential investment might look like and how best to educate and train employees and related stakeholders, especially business partners, suppliers and vendors who have access into the company network.

Some of the financial considerations for a small or medium sized business to incorporate a cybersecurity plan are:

• The cost of implementing and maintaining the security measures, such as software, hardware, training, and audits. The cost of implementing and maintaining the security measures, such as software, hardware, training, and audits.
• The potential savings from avoiding or minimizing the impact of cyberattacks, such as data breaches, ransomware, downtime, and lawsuits.
• The return on investment from enhancing the reputation, trust, and competitiveness of the business in the market.
• The compliance with the regulatory and contractual obligations that may require certain levels of cybersecurity.

To help you estimate the financial aspects of your cybersecurity plan, there are some cost calculator tools and resources available online, such as Cybersecurity Cost Calculator, Cybersecurity ROI Calculator, and Cybersecurity Planning Guide.

When it comes to training employees on the business cybersecurity plan, the business can train using a combination of methods, such as:

• Providing formal education on the policies, procedures, and tools that the business uses to prevent, detect, and respond to cyber threats.
• Sending simulated attack messages and challenging the employees to identify and report them.
• Gamifying the experience and rewarding the employees who demonstrate good cybersecurity practices and behaviors.
• Reviewing and updating the training content regularly to reflect the changing cyber landscape and the business needs.

Now for those business partners, suppliers and vendors who have access into the business network, a business can train them on their cybersecurity plan by using some of the following methods:

• Monitoring and logging the network access of the suppliers and vendors and reviewing the logs on a regular basis.
• Establishing boundaries and limiting the network access of the suppliers and vendors to the minimum necessary.
• Creating incident guides for third-party supply-chain attack scenarios and conducting tabletop exercises with key software vendors.
• Establishing point-of-contact connections and secure channels of communication with the suppliers and vendors.
• Specifying security requirements in third-party contracts and working with the procurement function to integrate these elements into any supplier contracts.

Before I close out this article let me share with you the current annual cost to businesses when it comes to cyber-attacks.

According to a report by Hiscox, the average financial cost of a cyber-attack to a small business in the US over 12 months is just over $25,000. However, the cost of cyber-attacks can vary depending on the size, industry, and location of the business, as well as the type, frequency, and severity of the attack. Some estimates suggest that the global cost of cybercrime will reach $11 trillion USD by 2025. Cyber-attacks can have a devastating impact on businesses, affecting their reputation, productivity, customer trust, and legal compliance. Therefore, it is essential for businesses to invest in cybersecurity measures and strategies to protect themselves from cyber threats.
