Criminals will want to target greater rewards from the disruption.

Protective Measures

Encryption technologies and automated threat detection and response are poised to play pivotal roles in fortifying IT infrastructures. The Security of Critical Infrastructure Act 2018 (SOCI) regulates critical infrastructure assets from 11 key industries in Australia.

Government Initiatives

Australia’s cyber shields strategy aims to protect critical infrastructure. Actions such as developing or joining a knowledge-sharing network or ensuring business vendors are working harder in areas of weakness lead to improved cybersecurity resiliency and maturity.

Mid-Market Business Cyber Security

Common Weaknesses

Mid-market companies will likely be targets of interest for threat actors in 2024. A lack of in-house cyber security resources and competencies will combine to make them softer targets than some of Australia’s larger, better-protected organisations and sectors. In the mid-market, it’s often not economically feasible to have more than probably two or three people in your cyber team. Criminals are out to exploit the weakest points.

Case Studies

Extended SOC support can boost mid-market defences. The Federal Government is focusing on smaller businesses as part of its cyber strategy. This includes a AUD $7.2 million (USD $4.9 million) voluntary cyber health check program and AUD $11 million (USD $7.4 million) for one-on-one assistance for businesses during cyber challenges, including attack recovery.

Improvement Strategies

  • Conduct regular cyber health checks.

  • Invest in extended SOC support.

  • Leverage government assistance programs.

Vendor Consolidation for Enhanced Security

Advantages of Consolidation

Enterprises are increasingly looking to consolidate the number of security vendors they use. Tool proliferation often leads to inefficiencies, such as increased alert noise and configuration challenges. According to Gartner, 75% of organizations in 2022 aimed to reduce their vendor count to decrease complexity, leverage commonalities, reduce administrative overhead, and enhance security effectiveness.

Implementation Challenges

While vendor consolidation offers numerous benefits, it also presents several challenges:

  1. Integration Issues: Merging different systems can be technically complex.

  2. Vendor Lock-in: Relying on fewer vendors can increase dependency and reduce flexibility.

  3. Cost Implications: Initial costs for consolidation can be high, even if long-term savings are expected.

Case Studies

Several organizations have successfully implemented vendor consolidation strategies:

  • Company A: Reduced its security vendors from 15 to 5, resulting in a 30% decrease in administrative overhead.

  • Company B: Achieved a more streamlined security posture by consolidating vendors, which led to a 20% reduction in alert noise.

Emerging Cyber Security Technologies
