Cybersecurity Trends to Watch in 2023

Introduction

As digital transformation accelerates across all sectors, the cybersecurity landscape continues to evolve at a rapid pace. For UK businesses, staying ahead of emerging threats is no longer optional—it's essential for survival. The cybersecurity challenges of 2023 are being shaped by shifting geopolitical tensions, increasingly sophisticated threat actors, and the expanding digital attack surface created by hybrid work environments and IoT proliferation.

In this article, we examine the key cybersecurity trends that UK organizations should be monitoring closely in 2023, and provide practical recommendations for strengthening your security posture.

The Evolving Threat Landscape

1. Ransomware Becomes More Targeted and Destructive

Ransomware attacks have evolved from opportunistic mass campaigns to highly targeted operations against organizations that can pay significant ransoms. In 2023, we're observing several concerning developments:

Triple extortion tactics: Beyond encrypting data and threatening its release, attackers are now also targeting customers and partners of the compromised organization, amplifying pressure to pay.
Industry-specific targeting: Threat actors are developing deep expertise in specific sectors like healthcare, manufacturing, and financial services, customizing attacks to exploit industry-specific systems and vulnerabilities.
Destructive elements: Even when ransoms are paid, we're seeing more cases where attackers sabotage systems or leave backdoors for future access.

Mitigation strategies: Implement comprehensive backup solutions with offline copies, adopt a zero-trust architecture, establish and test incident response plans, and consider ransomware-specific cyber insurance.

2. The Supply Chain Remains a Prime Target

Following high-profile incidents like SolarWinds and Kaseya, supply chain attacks continue to offer attackers tremendous leverage. This trend is accelerating in 2023 because:

A single compromise can provide access to hundreds or thousands of downstream organizations
Many vendors, especially smaller ones, may have less robust security practices
The interconnected nature of modern business makes it difficult to isolate vulnerabilities

UK businesses are particularly vulnerable given their participation in global supply chains and the regulatory complexity of post-Brexit trade arrangements.

Mitigation strategies: Implement comprehensive third-party risk management programs, conduct regular security assessments of critical suppliers, use code signing and verification, and develop contingency plans for critical vendor compromises.

3. Cloud Security Challenges Intensify

As UK organizations accelerate their migration to the cloud, security teams are struggling with several cloud-specific challenges:

Misconfigurations: Improperly configured storage buckets, excessive permissions, and insecure APIs continue to be leading causes of data breaches.
Identity management complexity: Managing identities and access across hybrid and multi-cloud environments is increasingly difficult.
Shared responsibility confusion: Many organizations still misunderstand the security responsibilities they retain when using cloud services.

Mitigation strategies: Implement cloud security posture management (CSPM) solutions, adopt cloud-native security tools, establish clear security policies for cloud resources, and regularly audit configurations against best practices.

Emerging Attack Vectors

1. Attacks on Remote Work Infrastructure

With hybrid work models becoming permanent for many UK organizations, remote access infrastructure remains a prime target for attackers:

VPN vulnerabilities are being actively exploited to gain initial access
Remote Desktop Protocol (RDP) remains a common entry point for ransomware attacks
Collaboration tools are increasingly targeted for both data theft and as entry points
Home networks and personal devices create security gaps that are difficult to manage

Mitigation strategies: Implement multi-factor authentication universally, adopt zero-trust network access solutions, keep remote access infrastructure patched, and enhance security monitoring for remote connections.

2. IoT and Operational Technology (OT) Vulnerabilities

The expanding universe of connected devices creates new attack surfaces that many organizations are ill-equipped to secure:

Industrial IoT deployments often connect previously isolated OT systems to the internet
Smart building technologies introduce network-connected HVAC, lighting, and access control systems
Medical devices in healthcare settings may run outdated software that cannot be easily patched
Consumer IoT devices used in work-from-home environments often have poor security controls

Mitigation strategies: Maintain comprehensive device inventories, segment networks to isolate IoT devices, implement IoT-specific security monitoring, and establish procurement standards requiring security features.

3. AI-Powered Attacks

Artificial intelligence and machine learning are being weaponized by threat actors to create more sophisticated attacks:

Deepfake technology is enabling more convincing social engineering attacks, including fake video and audio of executives
AI-generated phishing content is becoming more personalized and grammatically correct, making it harder to identify
Automated vulnerability discovery is accelerating the identification of exploitable weaknesses
Adversarial machine learning techniques are being used to evade AI-based security controls

Mitigation strategies: Establish verification protocols for sensitive requests, create out-of-band authentication procedures, train staff to recognize deepfakes, and implement defense-in-depth approaches that don't rely solely on AI-based detection.

Regulatory and Compliance Developments

1. Evolving UK Cybersecurity Regulations

The UK regulatory landscape continues to develop, with several important changes affecting organizations in 2023:

The UK's post-Brexit data protection regime is evolving, with potential divergence from GDPR
The Network and Information Systems (NIS2) Directive implementation will expand cybersecurity obligations for essential service providers
The Online Safety Bill introduces new requirements for digital service providers
Financial sector-specific regulations are becoming more prescriptive about cybersecurity controls

Response strategies: Maintain dedicated resources for regulatory monitoring, participate in industry forums sharing compliance best practices, and develop flexible security frameworks that can adapt to changing requirements.

2. Mandatory Breach Reporting Requirements

Requirements for prompt disclosure of security incidents are becoming more stringent:

Shorter timeframes for reporting breaches to authorities
More detailed disclosure requirements about the nature and impact of incidents
Expanded definitions of what constitutes a reportable incident
Increased penalties for failure to report in a timely manner

Response strategies: Develop comprehensive incident response plans with clear reporting procedures, establish relationships with relevant authorities before incidents occur, and conduct tabletop exercises that include the reporting process.

Defensive Strategies Gaining Momentum

1. Zero Trust Architecture

The zero trust security model has moved from theory to practical implementation across many UK organizations:

Identity-centric security: Shifting from network perimeters to identity as the primary security control
Micro-segmentation: Creating granular network segments to limit lateral movement
Continuous verification: Implementing ongoing authentication and authorization for all resource access
Least privilege access: Providing only the minimum permissions necessary for each user and application

Implementation guidance: Start with critical applications and data, focus on identity and access management fundamentals, implement strong authentication, and gradually expand controls across the environment.

2. Security Automation and Orchestration

Facing skills shortages and increasing threat volumes, organizations are turning to automation:

Security Orchestration, Automation and Response (SOAR) platforms to streamline incident management
Automated vulnerability management to prioritize and remediate weaknesses
Threat intelligence integration to proactively block known malicious indicators
Automated compliance monitoring to continuously verify security controls

Implementation guidance: Begin by automating routine, well-defined tasks, ensure human oversight of automated decisions, establish clear metrics to measure effectiveness, and gradually expand automation as confidence grows.

3. Cybersecurity Mesh Architecture

As traditional security perimeters dissolve, a more distributed approach to security is emerging:

Composable security services that can be deployed where needed
Centralized policy management with distributed enforcement
Integration of disparate security tools through common frameworks
Consistent security across hybrid and multi-cloud environments

Implementation guidance: Focus on integration capabilities when selecting security tools, establish standardized APIs and data formats, implement centralized identity governance, and develop consistent security policies across environments.

Human Factors in Cybersecurity

1. The Evolving Cybersecurity Skills Gap
