Threat Detection

Artificial Intelligence improves real-time threat detection by assessing large data sets, identifying patterns, and making predictions. AI analyses threats from user behavior and unusual patterns that can indicate a cyber attack. AI can minimize the impact of a security breach by automating threat detection, such as isolating affected systems or blocking malicious activities.

AI also detects malware threats. Malware includes the category of code or software that is intentionally targeted to harm. Since machine learning analyzes massive amounts of data, it can detect the presence of malware even before a user opens malicious files. It also detects the type of malware such as ransomware, bots, botnets, and so on.

Network Security Enhancement

With remote work taking over on-premises work environments in organizations, one of the biggest challenges was to ensure network security in a remote setting. Companies are digitizing more than ever before by updating internal and hybrid networks. Network topologies are complex to manage and require extensive security resources to manage communications, transactions, applications, etc.

What AI does here is reduce the challenge of managing extensive network security with network automation. Network automation leverages AI technology to maintain network devices such as firewalls and routers in a systematic and automated way. It uses software programs, scripts, and APIs to enhance its security and reduce the risk of human error.

Network automation is applicable in various environments including enterprises, Local Area Networks (LAN), data center networks, and wireless networks. Automation with AI also allows firms to respond quickly if there are changes in the network environment and make timely upgrades and backups to be protected from cyberattacks.;

Spam Filtering

One of the most common ways spammers use to trick users into giving them sensitive information is through phishing emails. For example, if a user clicks on a phishing email, AI can identify the change in the behavior and alert the security of a potential security breach. Phishing emails contain links and messages that look like it’s from an organization or a bank you trust. Some even target specific employees of a company posing as their superiors and bosses.

There have been various such cyber attacks in the past where users have been scammed and are asked to click on a link to make payment, but the link has malware, or they try to confirm financial information and so on. Thanks to the integration of AI in cybersecurity, these activities are identified in advance and automatically filtered into spam. AI analyzes the content and characteristics of emails and prevents them from reaching inboxes.

Threat Response and Risk Mitigation

Since threat detection is automated with AI, so is the threat response. AI-driven cybersecurity platforms can automatically detect and respond to threats by isolating affected systems and initiating incident response workflows. It can also help with vendor risk management as AI can trigger real-time alerts and notify security teams about the nature of the threat, its potential impact, and recommended actions.

Due to the instant response to a security threat, AI can prevent hackers from causing irreversible damage and reduce overall costs for an organization. It also reduces the burden on the cybersecurity workforce and assists them in securing the information systems.

User Authentication and Access Control

Two-factor authentication is a common way to shield your user accounts from getting their profiles hacked. Websites with user account features or contact forms containing sensitive information require a layer of protection.

AI provides this security by using facial recognition tools, CAPTCHA, and fingerprint scanners to authenticate during login attempts. This prevents scammers and hackers from fraudulent activities and prevents credential stuffing that can lead to a potential security breach of your network.

Behavior Analysis and User Profiling

AI cybersecurity tools can analyze user behaviors, interactions, and preferences over time. AI models utilize machine learning to detect deviations from regular behavior. For example, AI tools can easily detect unauthorized login attempts by irregular user behavior and malicious payment patterns. It can also check for irregular purchases and fraudulent transactions that don’t align with user profiling.

The best part is that AI only gets better. With time, AI trains, learns, self-corrects, and adapts which improves its accuracy in determining any abnormalities in user behavior and identifying potential threats. The self-correcting attribute of AI in cybersecurity facilitates businesses to create reliable cybersecurity mechanisms that can respond to emerging cyber threats.

Security Automation

Thanks to AI, many repetitive tasks and mundane activities get automated in cybersecurity. For example, your team doesn’t have to work on identifying low-risk alerts or tedious data enrichment as augmented security tools can easily take over such tasks and free up security professionals for strategic decision-making. Since machine learning algorithms can raise the baseline of threats, humans only need to intervene when there are high-order threats.

Cybersecurity performance and accuracy are now a combination of humans and AI and augmented security tools are a must for the security teams of tomorrow. With the basic tasks automated, cybersecurity professionals have a larger bandwidth to prevent, analyze, and respond to threats that compromise business functions and reputation
