In the realm of cybersecurity, the focus often gravitates toward advanced threats and cutting-edge technologies designed to counteract them. Yet, beneath the surface, it’s the seemingly innocuous gaps in foundational concepts that often create the most significant vulnerabilities within corporate infrastructures. These gaps, though hidden, can have devastating effects, leading to data breaches, operational disruptions, and financial losses.
The Hidden Gaps in Corporate Infrastructure
Corporate infrastructures are complex ecosystems composed of networks, systems, applications, and data, all interconnected and interdependent. Within this complexity, foundational concepts—if not properly implemented—can lead to critical gaps. These gaps can manifest in various ways:
1. Asset Mismanagement: Without a comprehensive understanding of all assets within the infrastructure, including their location and status, companies inadvertently create blind spots. These unaccounted-for assets often escape regular security checks and updates, becoming easy targets for attackers. Here are some common mistakes and their implications:
- MDM vs. Excel for Asset Management: MDM Systems provide real-time visibility and control, automatically detecting and managing new devices, and offering alerts for unauthorized access. However, organizations sometimes rely on Excel Spreadsheets, which are low-cost and simple but lack real-time updates and management capabilities. This approach is prone to human error and does not alert when new devices are added, making it unsuitable for dynamic environments. This can lead to missed rogue devices or unauthorized access points, significantly increasing security risks.
- Partial Asset Management: Some organizations attempt to manage only their most critical assets, assuming that this will save time and resources. However, this leaves other, less visible devices unmanaged. For instance, during a penetration test, we discovered that an unmanaged device, which wasn’t included in the main inventory, was used by attackers to compromise administrative credentials. This highlights the danger of overlooking less critical devices, which can become gateways for attackers.
- Lack of Regular Audits: Many organizations fail to conduct regular audits of their asset inventory. This oversight can lead to outdated records, where devices that are no longer in use remain on the network, or new devices are not added. This creates blind spots in the network that attackers can exploit, as unmonitored devices often lack the latest security patches and configurations.
- Shadow IT: Employees sometimes deploy their own devices or applications without the knowledge of the IT department, a practice known as shadow IT. These devices and applications often bypass the organization's security measures, creating vulnerabilities that the IT team is unaware of. This lack of visibility can lead to significant security gaps, as these unmanaged assets are not subjected to regular security checks.
- Ignoring End-of-Life (EOL) Devices: Organizations often delay replacing or decommissioning devices that have reached their end of life (EOL). EOL devices are no longer supported with security updates, making them easy targets for attackers. Maintaining such devices in the network creates significant security risks, as they can be exploited through unpatched vulnerabilities.
2. Inadequate Access Controls: A lack of stringent access controls can open the door to unauthorized users, allowing them to navigate through systems and extract sensitive data. This issue is compounded in environments where access privileges are not regularly reviewed or where excessive permissions are granted without proper justification. Here are some common mistakes and their implications:
- Excessive Privilege Access: Granting users more access than necessary is a common mistake. For example, giving all employees administrative privileges "just in case" can lead to a situation where a compromised user account can access critical systems or data that should be restricted. This over-provisioning can be exploited by attackers to escalate their privileges and gain control over more sensitive parts of the network.
- Lack of Role-Based Access Controls (RBAC): Many organizations fail to implement RBAC, where access is granted based on the user's role within the organization. Without RBAC, access rights are often assigned arbitrarily, leading to inconsistencies where some users have more access than they need while others lack necessary permissions. This inconsistency not only increases the risk of unauthorized access but also complicates the process of auditing and managing permissions.
- Failure to Regularly Review Access Permissions: Access permissions are often set during onboarding and then forgotten. Organizations that do not regularly review and adjust permissions according to role changes or employee departures risk leaving accounts with outdated and unnecessary access. This can lead to former employees or internal attackers having access to sensitive data long after their role has changed or their employment has ended.
- Weak Authentication Mechanisms and Lack of MFA: Relying solely on passwords, especially weak or default ones, without implementing multi-factor authentication (MFA) is a critical flaw. Attackers can easily exploit weak passwords to gain access to critical systems. The lack of MFA means there is no second layer of defense, making it easier for unauthorized users to breach systems. MFA should be a baseline requirement to ensure that even if passwords are compromised, attackers cannot gain easy access.
- Neglecting Conditional Access: Conditional Access is an advanced security measure that grants or blocks access based on specific conditions, such as the user’s location, device, or risk level. Many organizations overlook the importance of implementing Conditional Access policies, which can help prevent unauthorized access by enforcing stricter controls when certain conditions are met. For instance, blocking access from untrusted locations or devices can mitigate risks associated with compromised credentials. There has been more than one instance where I have seen a SOC report compromised credentials and MFA used to login and the attack was thwarted by conditional access policies.
- Shared Accounts: Using shared accounts for multiple users is a dangerous practice. It not only makes it difficult to track individual actions and accountability but also increases the risk of credential theft. If one user’s credentials are compromised, attackers can use the shared account to access systems undetected, with no clear audit trail of their activities. I have also observed MSP’s who use shared accounts and distribution phone numbers for MFA to login to client networks. Unfortunately, this was discovered in a forensics investigation, post incident.
- Overlooking Third-Party Access: Many organizations provide third-party vendors with access to their systems without proper oversight. This can include remote access or direct access to internal systems for support or maintenance. Without stringent controls and monitoring, these third-party accesses can become an easy target for attackers, who exploit the weaker security practices of vendors to gain a foothold in the organization’s network.
- Inadequate Segmentation of Access: Failing to properly segment access within the network allows attackers to move laterally across the organization once they gain initial access. For example, if a low-level employee's account is compromised, and there is no network segmentation, attackers can potentially reach sensitive areas, such as financial records or intellectual property, unchecked.
3. Outdated Systems and Software: Failure to keep systems and software up-to-date creates vulnerabilities that attackers can exploit. Organizations that neglect patch management due to resource constraints or oversight leave themselves exposed to risks that could have been easily mitigated. Here are some common issues related to outdated systems and software, including browser plugins:
- Unsupported Operating Systems: Running on outdated or unsupported operating systems (OS) is a major security risk. These systems no longer receive security patches or updates, making them easy targets for attackers who exploit known vulnerabilities. Organizations that continue using outdated OS versions often do so due to compatibility issues with legacy applications, but this trade-off significantly increases their risk profile.
- Legacy Applications: Legacy applications, especially those critical to business operations, are often left unpatched because they are difficult to update or replace. These applications can harbor vulnerabilities that attackers exploit to gain access to the network. The challenge lies in balancing the need to maintain business continuity with the necessity of securing these legacy systems.
- Outdated Browser Plugins and Extensions: Browser plugins and extensions are frequently overlooked in security strategies. Many organizations fail to update or monitor these small but significant pieces of software. Outdated plugins can be exploited by attackers to inject malicious code or gain unauthorized access to systems. Additionally, some plugins may no longer be supported by the browser or developer, increasing the likelihood of vulnerabilities going unpatched.
- End-of-Life (EOL) Hardware and Software: Continuing to use hardware and software that has reached its end of life (EOL) is a common issue. EOL products no longer receive updates, making them vulnerable to new threats. Organizations often keep using these products due to budget constraints or operational dependencies, but this decision can lead to serious security breaches.
- Unpatched Third-Party Software: Many organizations use third-party software to enhance their operations, but they often neglect to keep these tools updated. Unpatched third-party software can become an entry point for attackers, who exploit vulnerabilities to infiltrate the network. Ensuring that all third-party applications are regularly updated is essential to maintaining a secure environment.
- Compatibility Issues Leading to Delayed Updates: Sometimes, organizations delay updates due to concerns about compatibility with other systems or applications. While this might prevent short-term disruptions, it opens the door to long-term security risks. Attackers are quick to exploit known vulnerabilities, and delaying updates can give them the window of opportunity they need.
4. Neglecting User Training: Employees are often the first line of defense against cyber threats, yet they are frequently undertrained. Without regular, comprehensive training, employees may fail to recognize phishing attempts, fall prey to social engineering, or unknowingly introduce malware into the system. Here are key considerations and recommendations:
- Lack of Training on Foundational Elements of Deployed Systems: Employees often interact with complex systems without fully understanding the foundational security concepts that govern their use. For example, users may be unaware of the risks associated with bypassing security protocols, such as using weak passwords or ignoring software update prompts. Without proper training, employees may inadvertently compromise systems, opening the door to cyber threats.
- Phishing and Social Engineering Vulnerabilities: Phishing still remains as one of the most common attack vectors because it exploits human psychology rather than technical vulnerabilities. Without regular training, employees may not recognize phishing attempts, leading to compromised credentials or malware infections. Effective training programs should include simulated phishing exercises to help employees recognize and respond to suspicious emails.
- Foundational Cybersecurity Certifications and Training: To ensure that employees have a solid understanding of cybersecurity principles, organizations should encourage or require foundational certifications. Certifications such as CompTIA A+, Network+ and Security+, Microsoft Certifications, Amazon Certifications, or other training and certifications relevant to your implemented infrastructure provide employees with essential knowledge of security best practices, threat identification, and risk management. These certifications not only validate an employee’s understanding but also help build a culture of security awareness within the organization.
- Insufficient Training on Specific Tools and Systems: Employees often use specialized tools and systems without receiving adequate training on their security features and protocols. This can lead to misuse or underutilization of critical security features. For example, if users are unaware of how to properly configure Multi-Factor Authentication (MFA) or Conditional Access, they might leave these features disabled or improperly set up, reducing the overall security posture of the organization.
- Failure to Establish a Security-First Culture: Organizations that fail to instill a security-first mindset across all levels often find that employees view cybersecurity as an IT issue rather than a shared responsibility. Regular training sessions, security drills, and clear communication from leadership about the importance of security can help embed this mindset. When employees understand that they play a critical role in protecting the organization, they are more likely to follow best practices.
- Inadequate Incident Response Training: Even with robust security measures in place, incidents will occur. Employees need to be trained on how to respond to potential security breaches, including who to contact, what steps to take, and how to contain the threat. Incident response training should be part of regular security awareness programs, ensuring that employees can act quickly and effectively when needed.
Addressing the Gaps: Strengthening the Foundation
To prevent such scenarios, organizations must take a proactive approach to reinforcing foundational concepts:
- Conduct regular asset audits to ensure every component of the infrastructure is accounted for, monitored, and secured.
- Implement role-based access controls (RBAC) and regularly review access privileges to minimize the risk of unauthorized access.
- Prioritize patch management by creating a structured, timely update process that covers all systems, including legacy applications.
- Develop and rigorously test incident response plans to ensure readiness in the event of a breach, reducing response time and limiting damage.
- Invest in ongoing user training programs that emphasize the importance of cybersecurity awareness and equip employees to act as vigilant defenders against potential threats.
The unseen gaps within corporate infrastructure, often stemming from neglected foundational concepts, represent a significant risk to organizations. While advanced threats and technologies garner much attention, it’s the underlying weaknesses that often cause the most harm. By addressing these foundational gaps, companies can build a more resilient infrastructure, better equipped to withstand the ever-evolving landscape of cyber threats.
