What are the main cybersecurity threats organizations face?

Firstly, it's essential to understand that cybercriminals utilize various vectors to infiltrate companies. For instance, email remains the primary channel through which malware enters organizations, but threats can also emerge via endpoints, the cloud, or networks.

Ransomware is the most prevalent form of attack; this involves the use of specific malware to encrypt an organization's data, followed by a demand for payment in exchange for the decryption key.

Phishing, though a longstanding threat, continues to trick users into divulging sensitive information, such as login credentials or banking details, via fraudulent messages.

One notable example is "CEO fraud", where attackers impersonate an organization's senior executive, requesting a bank transfer or payment to a fictitious supplier.

Another method is "data leakage", which involves the theft of sensitive information later sold on the dark web or deep web.

Denial of Service (DoS) attacks are also common, overwhelming an organisation's infrastructure to cause significant operational disruptions.

Internal threats cannot be overlooked; current or former employees, and even contractors, may steal confidential information and pass it to competitors.

Social engineering is another growing concern, wherein individuals are manipulated into revealing confidential information that compromises an organisation's security.

Finally, there's unauthorised cryptomining, or cryptojacking, where attackers exploit a company’s computing resources to mine cryptocurrencies, resulting in system slowdowns and increased operational costs.

What role does artificial intelligence play in both defence and cyberattacks?

Artificial intelligence has been a part of cybersecurity for several years. AI enables predictive analysis through algorithms to identify vulnerabilities and anticipate potential cyberattacks. By analysing large volumes of data, it can detect threats or anomalous patterns in real-time.

It also facilitates the automation of security responses and enhances authentication and access control systems.

On the offensive side, cybercriminals use AI to automate and refine their attacks, such as creating more sophisticated phishing schemes based on social media data.

AI can also develop more advanced malware that evades traditional defences, making it harder to detect.

While AI assists organisations in identifying weaknesses in their security systems, it equally aids cybercriminals in finding these vulnerabilities first. Therefore, it’s crucial for organisations not only to adopt AI for defence but to remain vigilant about how it may be used against them.

What measures should organisations take to enhance their cybersecurity?

To strengthen IT security, organisations should implement a combination of strategies.

Conduct thorough risk assessments and management. Ideally, regular audits and ethical hacking should be carried out to identify vulnerable applications or data repositories. Evaluating potential attack risks can help anticipate security measures.

Develop a comprehensive IT security policy and master plan to outline clear, up-to-date strategies for protection against threats.

Access control is vital, including robust authentication protocols and effective password management. Data encryption is also critical in this regard.

Network security is another priority. In addition to intrusion prevention systems (IPS), organisations should deploy tools such as Network Detection and Response (NDR) to identify malware attacks. Segmenting networks is also essential to limit the spread of attacks in the event of a breach.

It’s important to use VPNs to ensure remote connections remain secure and unaltered. Keeping all devices, systems, and applications updated is another fundamental requirement.

Organisations must maintain rigorous backup processes, using tools to securely store data both on-premises and in the cloud.

Above all, user awareness and training are key to ensuring employees are well-informed about evolving cyberattack methods and know how to respond appropriately.

What trends do you foresee in cybersecurity over the coming years?

I anticipate increased use of AI and machine learning in cybersecurity, alongside the growth of cloud security tools and Zero Trust strategies to protect data in transit and at rest.

Identity and access protection will continue to evolve to ensure that individuals accessing systems are who they claim to be.

Internal threats are likely to increase, so it's essential for companies to be prepared for this growing risk.

Quantum computing poses another challenge, as it threatens to disrupt current cryptographic systems. Organisations will need to update their encryption methods to more advanced standards.

Cybersecurity as a service is another growing trend, with companies increasingly relying on specialised providers due to the shortage of skilled professionals.

Finally, we will see a rise in proactive cybersecurity. AI-driven solutions will enable companies to detect potential security incidents before they occur.
