Cyber Security & Resilience Consulting Services
Cyber security involves the practice of safeguarding systems, networks, and data against unauthorised access, attacks, and damage. Cyber resilience is the capability to withstand, detect, and recover when an incident successfully penetrates these defences. Collectively, they constitute a continuous framework for managing risk, budget, and controls, rather than relying on a single product: the objective is to prevent attackers from entering where feasible, and to maintain business operations when they do breach the perimeter.
Scope of coverage
Protection
- Network and endpoint protection: Implementing firewalls, segmentation, and monitoring to impede intruders.
- Access control: Determining which individuals can access specific systems, often representing the most cost-effective line of defence.
- Identity management: As compromised accounts are a primary vector for entry, Multi-Factor Authentication (MFA) and the principle of least privilege are critical.
- Data protection: Applying encryption, backups, and retention policies to data whether at rest or in transit.
Detection, response, and recovery
- Detection: Identifying anomalous activity while it remains containable, before it can proliferate.
- Containment: Rapidly isolating affected systems or accounts to prevent the threat from spreading across the infrastructure.
- Recovery: Restoring services and data from verified, current, and tested copies within a timeframe the business can tolerate.
- Continuity: Maintaining essential operations, potentially in a degraded state, whilst full recovery efforts are underway.
Key areas of impact
- Remote work: Devices operating outside the office network extend the attack surface and erode traditional perimeter security.
- Third-party access: Vendors and integrations often possess more credentials than internal staff, increasing risk.
- Ransomware: Modern attacks typically assume initial access has been gained. The distinction between a minor disruption and a major crisis largely depends on the robustness of the recovery design.
- Backup integrity: A backup accessible to the same attacker as the live system offers no true protection. Offline or isolated copies are essential.
Why prevention alone is insufficient
No control stack can block every attempt. Security reduces the frequency of successful attacks, while resilience dictates the outcome after a breach occurs. A comprehensive programme must account for both aspects.
Considerations for assessment
- Cost versus coverage: Since full tooling is costly, prioritise the assets whose loss would cause the most significant harm.
- Recovery targets: Determine how long each system can remain offline before the financial cost surpasses that of recovery. This should be a realistic figure for each system, rather than an optimistic one.
- Maintenance burden: Security tools generate alerts and require updates. Without management, they become a source of noise and potential gaps.
- Testing: An incident response or recovery plan that has never been tested remains a draft. Regular testing identifies gaps cost-effectively, replacing uncertainty with measured action.
- Decision authority: Clearly define who has the power to declare an incident, order a shutdown, or initiate a restore. These roles must be established in advance, not improvised during a crisis.
- Compliance: Regulations increasingly specify minimum controls, recovery expectations, and reporting obligations.
How NobleConsul can assist
Where appropriate, NobleConsul can support these decisions through consulting activities, such as technology evaluation, solution design, and implementation guidance for protective controls. This also includes reviewing detection and recovery coverage, designing realistic recovery targets for each system, and planning tests to verify that the design is effective.
