Managing Your Unmanaged Attack Surface for Professional Services IT Managers

Managing Your Unmanaged Attack Surface for Professional Services IT Managers

Unmanaged attack surfaces present significant risks to medium-sized businesses in professional services, especially in accounting. These risks can lead to malware delivery and potential data breaches. The main risk is failing to identify and protect all potential entry points for cyber threats. The first step is conducting a comprehensive audit of all digital assets and their security vulnerabilities. When the complexity of the attack surface exceeds your team's capability, it's time to consult a cybersecurity expert.

Who this is for – IT Managers in Professional Services

This guide is specifically for IT managers in the accounting sub-industry of professional services, operating within medium-sized businesses. With a developing security stack maturity and an elevated urgency level, these IT managers are focusing on compliance with frameworks like GDPR while managing risks associated with a primarily remote workforce and a cloud-first environment.

Why this matters – Importance of Attack Surface Management

In the accounting sector, maintaining customer trust and ensuring data protection is paramount. An unmanaged attack surface can lead to operational disruptions and financial losses, undermining the credibility of fractional CFO services. Compliance with GDPR is not just a regulatory requirement but a trust factor for clients. A breach can result in hefty fines and damage to reputation, impacting client relationships and business growth.

What the risk means – Understanding Unmanaged Attack Surfaces

An unmanaged attack surface refers to all potential pathways through which a cyber threat can access your network, including unsecured devices, outdated software, and rogue access points. Malware delivery is a common attack vector that exploits these vulnerabilities to inject malicious software, potentially leading to data breaches and operational shutdowns. In the impact stage, the attacker can access or damage critical data, such as cardholder information, prompting regulatory inquiries and financial liabilities.

What can go wrong – Consequences of Poor Management

Without proper management, your attack surface can lead to several scenarios:

  • Operational Impact: Malware can disrupt accounting operations, leading to downtime and missed deadlines.
  • Compliance Violations: GDPR non-compliance can result in fines and legal actions.
  • Financial Consequences: Breaches can incur direct financial losses and increased insurance premiums.
  • Loss of Trust: Clients may lose confidence in your ability to protect their sensitive information.

What to do first to manage your attack surface

Immediate actions to mitigate these risks include:

  1. Conduct an Attack Surface Audit: Identify all digital assets and assess their vulnerabilities.
  2. Implement Partial MFA: Strengthen access controls by ensuring that multi-factor authentication is used where possible.
  3. Enhance Endpoint Security: Complete the rollout of Endpoint Detection and Response (EDR) solutions to monitor and protect all endpoints.

30-day action plan for initial attack surface control

Owner Action Outcome

Compliance Lead Review and update GDPR compliance measures Assurance of regulatory compliance

90-day improvement plan for sustained security

  • Prevention: Regularly update software and patch vulnerabilities. Train employees on security best practices.
  • Detection: Implement continuous monitoring tools to detect unusual activities.
  • Response: Develop a clear incident response plan and conduct simulated breach exercises.
  • Recovery: Ensure that data backup procedures are robust and tested for efficient restoration.
  • Governance: Establish a governance framework to oversee security policies and compliance adherence.

Vendor and tool considerations for accounting IT managers

Medium-sized businesses in accounting may benefit from using GRC platforms or engaging with vCISOs to manage complex security needs. When selecting tools or service providers, consider their ability to integrate with existing systems, their compliance support for GDPR, and their reputation in the industry.

Common mistakes in managing attack surfaces

Accounting IT teams often underestimate the complexity of their attack surface, leading to incomplete audits. Additionally, they might rely solely on periodic scans rather than continuous monitoring, leaving gaps in detection. A better approach is to maintain an up-to-date inventory and use automated tools for real-time insights.

FAQ on attack surface management

What is an unmanaged attack surface?

An unmanaged attack surface is the sum of all potential entry points that a cyber threat can exploit to access your network. It can include unsecured devices, outdated software, and weak access controls.

How does malware delivery work?

Malware delivery involves the injection of malicious software into a system, often through phishing emails or compromised websites, to gain unauthorized access or cause damage.

Can partial MFA provide sufficient security?

While partial MFA is better than none, it's vital to aim for full implementation across all access points to maximize security and reduce the risk of unauthorized access.

What is the role of a GRC platform in managing attack surfaces?

A GRC platform helps in managing governance, risk, and compliance by providing tools to monitor vulnerabilities, enforce policies, and ensure adherence to regulations like GDPR.
