- ## Automated incident response
AI systems can automatically perform containment, eradication and recovery tasks to rapidly respond to security incidents. This allows faster neutralization of threats and lower damage costs.

- ## Improved threat intelligence
AI uses big data analytics on threat data to derive real-time insights on emerging risks. This enhances situational awareness so that defenses can be adapted dynamically based on the latest attack trends.

- ## Reduced human error
AI reduces delays and errors by automating tedious and complex security tasks. With AI handling the legwork, human analysts can focus on higher-value threat investigations and response duties.

- ## Increased scalability and efficiency
AI-driven cybersecurity strengthens defenses while lowering costs through automation. Highly scalable AI systems enable streamlined protection across hybrid cloud infrastructures and distributed networks.

### How AI is used in cybersecurity

Here are some of the major applications of AI for cyber defense:

## Intrusion detection and prevention systems (IDPS)

Intrusion Detection and Prevention Systems (IDPS) are essential cybersecurity tools designed to safeguard computer networks from unauthorized access and malicious activities. These systems continuously monitor network traffic and system behavior, actively searching for signs of intrusion, such as suspicious patterns, malware, or abnormal user behavior. 

IDPS serves a dual purpose: detection and prevention. Detection involves identifying potential threats and alerting security teams to investigate further. Prevention, on the other hand, takes immediate action to block or mitigate threats in real-time. IDPS play a critical role in maintaining the integrity and security of digital assets, helping organizations proactively defend against cyber threats and minimize the potential for data breaches and network compromise.

## User and entity behavior analytics (UEBA)

User and Entity Behavior Analytics (UEBA) is a sophisticated cybersecurity methodology that deploys machine learning and artificial intelligence algorithms to scrutinize and comprehend user and entity activities within a network. UEBA establishes a baseline of typical behavior patterns, then continuously monitors for deviations or anomalies. It takes into account a myriad of parameters, such as login times, data access, application usage, and more, to detect potentially malicious or unauthorized activities. By identifying outliers, UEBA assists in the early recognition of insider threats, compromised accounts, or abnormal system actions, enabling rapid response and fortification of network security against evolving cyber threats.

## Security information and event management (SIEM) systems

Security Information and Event Management (SIEM) systems are intricate cybersecurity platforms designed for comprehensive threat detection and incident response. They aggregate and normalize data from a wide array of sources, including firewalls, intrusion detection systems, and servers, to provide a holistic view of an organization's security landscape. SIEM employs rule-based and machine learning algorithms to analyze this data, identifying patterns and anomalies that may indicate security incidents. It correlates disparate events to generate real-time alerts, allowing security teams to respond swiftly. Additionally, SIEM systems aid in compliance adherence by offering in-depth reporting and forensic analysis. Their technical prowess makes SIEM a linchpin in modern security operations.

## Endpoint security

Endpoint security, in the technical realm of cybersecurity, encompasses a suite of tools and practices designed to fortify individual devices (endpoints) within a network. These tools include antivirus software, host-based firewalls, intrusion detection and prevention systems, and encryption mechanisms. Endpoint security aims to prevent, detect, and respond to a spectrum of threats, from malware and ransomware to insider attacks. It employs heuristics, behavioral analysis, and signature-based detection to identify and mitigate risks. With the increasing prevalence of remote work and mobile devices, robust endpoint security is crucial in maintaining data confidentiality and safeguarding against advanced threats, forming a fundamental pillar of modern cybersecurity architecture.

## Vulnerability management

Vulnerability management utilizes specialized SAST (static application security testing) and DAST (dynamic application security testing) tools to continuously monitor applications and infrastructure for security misconfigurations or coding flaws. These scans identify vulnerabilities like SQL injections, cross-site scripting, insecure APIs, and unpatched systems. Once found, vulnerabilities are rated using CVSS (Common Vulnerability Scoring System) risk scores to prioritize remediation. Organizations create plans to patch or mitigate the most critical risks first. Automated patch management solutions can deploy fixes across systems. Vulnerability assessment reports track remediation progress. Effective vulnerability management combines asset inventory, risk analysis, threat modeling, penetration testing, and security instrumentation to find and fix security gaps before exploitation.

### Threat hunting

Threat hunting leverages endpoint detection and response tools, SIEMs, and threat intelligence feeds to actively identify IOCs and TTPs of advanced adversaries. Skilled hunters create statistical baseline models of network traffic and asset behaviors, enabled by machine learning algorithms. By applying behavioral analytics, hunters can flag anomalies indicative of lateral movement, command and control communications, privilege escalation, and exfiltration. Expert threat hunters deeply investigate outliers, pivoting through related observables to rapidly uncover the scope of any active intrusions. Technical threat hunting provides proactive mitigation by continuously monitoring for stealthy, persistent threats that bypass traditional perimeter defenses. Robust threat hunting teams are a critical capability for organizations to validate security controls and expose gaps exploited by sophisticated actors.

## Incident response

Robust incident response relies on integrating threat intelligence feeds, endpoint detection, and centralized log analysis. Security orchestration playbooks automate containment of compromised hosts by isolating VLANs, disabling user accounts, and blocking IOCs. Forensics utilize endpoint and network forensics tools to uncover attack chains, identify patient zero, and determine data exfiltrated. Reverse engineering of malware executables provides IOCs to scan for additional infections. Post-mortems extract key learnings to improve tooling, monitoring, and staff response flows. Tabletop exercises test and refine IR methodologies. SecOps metrics quantify dwell time, time-to-resolution, and costs. Continual enhancement of detection, integration, automation, and cyber resilience prepares teams to efficiently triage, investigate, and remediate advanced persistent threats.
