This blog explores the pivotal role of AI in cybersecurity threat intelligence and how businesses can use it to enhance their security posture and incident response capabilities.
Understanding Cyber Threat Intelligence
To understand CTI, the first thing you as a business owner need to learn is “what is cyber threat intelligence”. Cyber threat intelligence solutions collect information from various sources, such as security logs, threat feeds, and open-source intelligence, and transform it into actionable intelligence.
CTI analyzes this information to provide insights into threat actors’ tactics, techniques, and procedures. As a result, you can proactively identify vulnerabilities, prioritize security efforts, and implement appropriate defensive measures to protect your networks, systems, and data.
Types of Cyber Threats and Their Impact On Organizations
Now that you know what is threat intelligence in cyber security, you must learn about various types of cyber threats hackers deploy to gain access to confidential business data.
Malware, short for “malicious software,” is designed to harm or compromise computer systems, networks, or data. It encompasses a wide range of malicious programs, including viruses, worms, trojans, ransomware, and spyware. Malware can infiltrate systems and exfiltrate sensitive data, such as customer information, intellectual property, financial records, or trade secrets. It can also disrupt normal business operations by encrypting files, locking systems, or deleting critical data.
Phishing attacks allow cybercriminals to deceive individuals into disclosing sensitive information by impersonating trustworthy entities. Due to this, they can result in data breaches and unauthorized access to company systems. These attacks can also have financial implications for organizations, as stolen details can be used to conduct fraudulent transactions. This can damage an organization’s reputation and erode customer trust.
Distributed Denial of Service (DDoS)
Distributed Denial of Service (DDoS) uses a botnet to overwhelm a targeted system or network with excessive traffic or requests. This exhausts the target’s resources, making its services unavailable to legitimate users. During this attack, organizations cannot access critical systems, leading to a loss of business productivity. In some cases, DDoS attacks are launched as a smokescreen to divert attention from other malicious activities, such as data breaches or network intrusions.
Zero-day exploits are vulnerabilities or weaknesses in software or systems that are unknown to the software vendor and for which no patch or fix has been released. Cyber attackers can discover these vulnerabilities and exploit them to gain unauthorized access to sensitive information. They can also use it to disrupt critical systems or networks, causing downtime and reputational damage.
SQL Injection is a web application vulnerability in which malicious SQL code is inserted into an application’s database query, allowing attackers to manipulate or retrieve data from the database. These attacks can compromise entry points of the application or underlying system to execute arbitrary commands, upload malicious files, or execute remote code. In short, the attackers gain complete control of the system to use it for illegal purposes.
Why Organizations Leverage Proactive Cyber Threat Intelligence
Organizations can use proactive cybersecurity threat intelligence (CTI) to enhance their security posture and effectively combat the ever-evolving threat landscape. Businesses can also leverage it to anticipate emerging threats before they manifest into full-blown attacks.
Proactive CTI empowers organizations to mitigate potential risks by providing actionable insights into current and future threats. It helps organizations stay informed about recent cyberattacks to effectively implement security controls and patch vulnerabilities to prioritize risk mitigation.
Using vigorous CTI, companies can even enhance their incident response capabilities. They can develop incident response plans and establish communication channels to minimize the impact of security incidents.
