According to a recent industry report, over 90% of cybersecurity professionals believe AI and machine learning will dramatically transform network security in the next 3-5 years.

AI Improves Threat Detection

One of the biggest challenges in cybersecurity is promptly detecting increasingly sophisticated threats and abnormal behavior. Traditional rule-based security tools that rely on matching known signatures and patterns are not able to keep up with today’s advanced and rapidly evolving threats. AI excels at recognizing anomalies and identifying emerging threats by learning patterns within massive volumes of high-velocity security data.

Machine learning algorithms can establish baselines for normal network traffic, system and user behavior. By continuously monitoring for deviations, AI models can quickly flag suspicious events that warrant further investigation. For example:

  • Network traffic analysis – AI can analyze network traffic patterns and communications to detect command-and-control activity associated with botnets and malware. The AI models can flag surges in data transfers, unusual spikes in activity, and other network anomalies.
  • Log analysis – AI techniques can rapidly parse through vast amounts of log data and system events to identify signs of brute force login attempts, privilege escalations, data exfiltration, and other security incidents. This is far faster and more efficient than manual log reviews.
  • Malware detection – Deep learning algorithms are extremely effective at analyzing attributes of files and programs to detect zero-day malware and advanced persistent threats (APTs) that easily bypass traditional signature-based antivirus tools. The AI can identify code anomalies and subtle behavioral indicators of malicious intent.

Going into 2023, AI-powered threat detection tools and services will become a mainstream component of cybersecurity stacks. Cloud providers such as Microsoft and Amazon Web Services already offer AI-infused SIEMs and security analytics services like Microsoft Azure Sentinel and Amazon GuardDuty.

These can ingest massive data streams from across cloud workloads to detect threats. On-premises cybersecurity solutions are also rapidly adding integrated AI capabilities for behavior analysis and anomaly detection.

With cybercriminals continuously innovating their methods, the ability of AI models to find needles in massive haystacks and connect subtle dots between events will be critical for keeping up with the threat landscape. Organizations will need to ensure they have the necessary data, infrastructure and talent to fully capitalize on the benefits of AI for robust threat detection.

AI Aids Threat Hunting

Threat hunting refers to the practice of proactively searching through IT environments to identify threats that may have evaded existing security tools and gained a foothold within systems and networks. This allows security teams to get ahead of threats before they can cause damage. But combing through massive volumes of data across complex modern technology stacks is an immensely tedious and labor-intensive process, often compared to finding a needle in a haystack.

AI and automation provides a force multiplier for threat hunting capabilities in several key ways:

  • Network mapping – AI can automatically discover all assets, connections and data flows across cloud, on-prem and hybrid environments. This provides an updated blueprint of the attack surface and potential lateral movement pathways.
  • Behavioral analytics – By establishing dynamic baselines for entities like users, devices and applications, machine learning models can flag anomalies that may be indicative of compromised credentials, command and control activity, data staging and other early threat behaviors.
  • Pattern recognition – AI examines vast streams of data flowing across networks to highlight potentially malicious sequences of events, such as privilege escalations followed by lateral movement. This connects the dots to piece together tactics of advanced attackers.
  • Automated hunting – AI continuously hunts through datasets and events, leveraging intelligence to identify indicators of compromise and abnormalities. This frees up human investigators to focus on higher-value analytical efforts.
  • Entity resolution – Graph algorithms link related entities to uncover hidden relationships between users, endpoints and events that may point to stealthy threats.

Key players in the AI-powered threat hunting space include IBM, Palo Alto Networks, RSA, Huntress and Sift. In 2023, more organizations will leverage these AI capabilities for proactive threat detection across cloud and hybrid environments. This will enable faster discovery of threats that may have already infiltrated networks and lay dormant – before major damage can occur.

AI Orchestrates Automated Responses

When a cyberattack or breach occurs, time is of the essence. The quicker security teams can contain an incident and shut down attack pathways, the less damage is inflicted. But manual incident response processes often struggle to keep pace with the speed and complexity of modern threats. AI and automation provides a force multiplier for accelerating incident response.

AI empowers security software to immediately execute tactical containment and remediation actions without waiting for human direction. For example:

  • Compromised user accounts exhibiting signs of takeover like impossible travel can be instantly disabled or prompted for password resets to cut off attacker access.
  • Application credentials and permissions being abused by an attacker can be revoked to limit lateral movement.
  • Infected endpoints can be isolated from the network to prevent malware from spreading.
  • Suspicious IP addresses or domains can be blocked at the firewall to disrupt command-and-control channels.
  • Sandboxes and deception tools can be dynamically deployed to safely analyze and engage with threats.

AI virtual assistants can also help automate the initiation and coordination of broader incident response workflows. This includes notification trees, evidence gathering, system backups, and activation of emergency procedures. Orchestration integrations further allow AI to leverage other security tools like SIEMs, endpoint detection and response (EDR), and secure web gateways to immediately enact containment measures.

Key players in the AI-driven automated response market include Microsoft, FireEye, IBM, Fortinet, Rapid7, Cynet and SentinelOne. Organizations will increasingly rely on AI to institute instantaneous countermeasures and accelerate human-led processes. This will drastically reduce dwell times for attackers and enable faster bounce-back from cyber incidents.

AI Fortifies IoT and Edge Security

The Internet of Things (IoT) explosion is leading to billions of connected smart devices deployed across homes, factories, cities and other environments. This massive scale of distributed endpoints with limited security capabilities creates a perfect storm for cyber attacks. Additionally, more processing and data storage is shifting to localized edge infrastructure outside of traditional network perimeters. AI and machine learning is becoming indispensable for securing these sprawling IoT and edge ecosystems.

Some key ways AI strengthens IoT and edge security:

  • On-device detection – Lightweight AI agents can be embedded directly on processor-constrained devices like cameras and sensors to analyze behavior patterns and detect compromised credentials or anomalous activities indicating attacks.
  • Network monitoring – Centralized AI systems digest and correlate insights from massive fleets of IoT devices across different locations to identify coordinated attacks spanning multiple endpoints.
  • Edge protection – AI safeguards edge data centers by scanning memory, runtimes and data flows for risks. It also provides encryption, access controls and other data protection measures tailored to edge environments.
  • Updates – Machine learning analyzes device telemetry and vulnerability data to intelligently determine optimal scheduling for pushing security patches and firmware updates across millions of IoT devices.

Major cloud providers including AWS, Microsoft and Google offer AI-infused IoT security services. Specialized platforms from vendors such as CrowdStrike, Akamai, VDOO, and Armis embed advanced AI directly on individual devices all the way up to the cloud. As IoT and edge adoption explode, AI and automation will become mandatory aspects of scalable security strategies in 2023 and beyond.

With regulations like GDPR, CCPA, and emerging data privacy laws worldwide, businesses face a complex compliance burden to implement appropriate security controls around personal data collection and processing.

However, sensitive data often resides across highly fragmented environments encompassing on-prem systems, cloud services, remote endpoints and more. Manually identifying where regulated data exists and how it flows is extremely challenging.

AI and automation provides a scalable solution to tackle modern data privacy compliance requirements:

  • Data discovery – Natural language processing and deep learning scours unstructured data contained in documents, communications, source code and other corpora to accurately pinpoint personally identifiable information. This builds visibility into where regulated data exists.
  • Classification – Machine learning analyzes data sets and applies tags indicating sensitivity levels, types of personal information contained, and jurisdiction of origin. This enables appropriate policies to be applied.
  • Mapping – Automated data lineage diagrams trace how personal information flows across systems, services and users. This illuminates blindspots and risks.
  • Enforcement – As data moves, AI dynamically applies encryption, tokenization, masking and access controls to enforce privacy policies and standards.
  • Monitoring – Continuously monitor for improper data handling, unauthorized access, or policy violations regarding sensitive information.

Leading this new wave of AI-powered data privacy platforms are vendors such as BigID, Ground Labs, Microsoft, AWS, and IBM. Organizations must embrace AI to efficiently comply with expanding data privacy regulations across their digital estates. Automating discovery, classification, protection and monitoring will be critical.

  • HR information on employees targeted by social engineering and insider threats based on roles, performance issues, etc.
  • News, social media and brand monitoring revealing external threats, like hacktivist targeting.

Natural language processing and knowledge graphs are key technologies for extracting insights from these disparate context sources and identifying relationships between them. This allows AI to analyze threats with a holistic understanding of business criticality and respond based on risk severity, rather than just technical indicators. As this contextual breadth and depth expands, security AI will continuously improve in accuracy, relevance and overall efficacy.
