Practical Cybersecurity Tips for Effective Vulnerability Management


Cybersecurity often gets sidelined in organizations, particularly when they’re scaling rapidly.

The focus tends to be on growth and expansion, with cybersecurity considered an afterthought or only addressed when compliance requirements demand it.

In many instances, the complexity of it often leads to dismissal with a “what are the odds” mindset. But with the right help, cybersecurity is an asset. It not only provides security, but also builds trust, improves efficiency and ultimately converts into a competitive advantage. 

At Aerstone, spanning over 20 years, we’ve been dedicated to delivering cybersecurity solutions tailored to businesses of all sizes. Drawing from our extensive experience, we’ve identified six indispensable cybersecurity tips applicable to every organization.

Aerstone Blog Graphic Practical Cybersecurity Tips for Effective Vulnerability Management - 1 Adopt a Zero Trust Networking Approach

Cybersecurity Tip 1: Adopt a Zero Trust Networking Approach

Embrace the Zero Trust networking model. This approach operates under the assumption that no entity, whether internal or external, should be automatically trusted, and all interactions should be rigorously verified and authenticated. 

Most of the time, it’s not even just about trust. Individuals within organizations can fall prey to deception, leading to vulnerabilities that reverberate throughout the entire organization. The reality is, even highly trained security professionals are susceptible to deception.

Implement strict access controls, multi factor authentication, and continuous monitoring to verify and secure every user, device, and application accessing your network. By adopting a Zero Trust approach, you can mitigate the risk of insider threats and unauthorized access.

A recent research study revealed that on average, 15% of companies have over 1,000,000+ files open to every employee and another revealed that 74% of cybersecurity breaches are caused by human error, reiterating the importance of a zero trust networking approach.

Let’s look at some ways to action this cybersecurity tip:


Implement Strict Access Controls

Implement granular access controls that restrict access to resources based on the principle of least privilege. Instead of granting broad permissions by default, only provide users with the minimum access necessary to perform their specific tasks. For example, use role-based access control (RBAC) to define access rights based on job roles and responsibilities.


Multifactor Authentication (MFA)

Require users to authenticate their identities using multiple factors, such as passwords, biometrics, smart cards, or tokens, before granting access to network resources. By adding an extra layer of authentication beyond just passwords, MFA strengthens security and mitigates the risk of compromised credentials.


Implement Continuous Monitoring

Implement continuous monitoring and real-time threat detection capabilities to identify and respond to suspicious activities and anomalies within the network. Utilize security information and event management (SIEM) systems, intrusion detection systems (IDS), and endpoint detection and response (EDR) solutions to monitor network traffic, log data, and endpoint activities for signs of unauthorized access or malicious behavior.


Enable Micro-Segmentation

Divide the network into smaller, isolated segments or zones using micro-segmentation techniques. By creating barriers between different parts of the network, organizations can contain the spread of cyber threats and limit the impact of potential breaches.

Cybersecurity Tip 2: Invest in Cybersecurity Culture and Awareness

EmbrCultivate a strong cybersecurity culture within your organization by promoting awareness and education among employees at all levels. Offer regular training sessions, workshops, and simulated phishing exercises to educate employees about common security threats and best practices. Encourage a culture of vigilance and accountability, where employees feel empowered to report suspicious activities and adhere to security policies and procedures diligently.


Encourage a Culture of Vigilance and Accountability

Foster a sense of ownership and responsibility for cybersecurity among all employees by promoting a culture of vigilance and accountability. Encourage employees to remain vigilant for unusual or suspicious activities, both online and offline, and empower them to report any security incidents or concerns to the appropriate channels. Recognize and reward employees who demonstrate proactive security behaviors and contribute to a safer working environment.


Lead by Example

Leadership plays a crucial role in shaping organizational culture, including cybersecurity culture. Senior executives and management should lead by example by demonstrating a commitment to cybersecurity best practices and actively participating in awareness initiatives. By visibly prioritizing security and emphasizing its importance, leadership sets a positive tone for the entire organization and reinforces the value of cybersecurity culture.


Integrate Security into Everyday Practices

Embed security awareness into everyday business practices and workflows to ensure that cybersecurity remains top of mind for employees. Incorporate security reminders, tips, and updates into internal communications, meetings, and training materials. Encourage collaboration between IT and other departments to address security concerns and integrate security measures seamlessly into existing processes.

Cybersecurity Tip 3: Conduct Penetration Testing

Another important cybersecurity tip to remember is to conduct non-automated penetration testing. Regularly subjecting systems, networks, and applications to simulated cyber-attacks, you can proactively identify and address security vulnerabilities before others exploit them. 

When it comes to vulnerabilities, the conventional vulnerabilities such as SQL Injections have declined due to advancement in development frameworks and technologies. Modern frameworks have built-in security features that effectively neutralize such threats. 

Instead, more sophisticated security challenges such as privilege escalation attacks are on the rise. Privilege escalation attacks involve gaining unauthorized access to higher-level permissions. These attacks exploit flaws in application logic or system configurations. They result from business logic errors and are often overlooked in automated testing.

Well thought out penetration testing allows organizations to stay ahead of emerging threats, mitigate potential risks, and enhance their overall security posture. It provides valuable insights into the effectiveness of existing security controls, incident response capabilities, and employee awareness.

It also helps organizations comply with regulatory requirements and industry standards, demonstrating a commitment to safeguarding sensitive data and protecting against cyber threats. Ultimately, by investing in regular penetration testing, organizations can bolster their resilience against cyber-attacks and minimize the impact of security breaches on their operations, reputation, and bottom line.

Cybersecurity Tip 4: Carry out Red Team Exercises

Conduct regular red team exercises to simulate real-world cyberattacks and test your organization’s incident response capabilities. Red teams, composed of skilled ethical hackers, attempt to penetrate your network and systems using the same tactics and techniques as real attackers. By identifying weaknesses and vulnerabilities before malicious actors do, red team exercises enable organizations to strengthen their defenses and improve their ability to detect and respond to security incidents.

The red team leverages a diverse range of tools, methodologies, and attack vectors to identify weaknesses and vulnerabilities across your network infrastructure, applications, and systems.

They serve as a litmus test for your organization’s incident response capabilities by challenging the effectiveness of detection, response, and mitigation processes. By simulating cyber-attacks in a controlled environment, organizations can evaluate the timeliness and efficacy of their incident response procedures and fine-tune their response plans accordingly.
