Top 7 Essential Steps to Improve IT Security

IT security is more than important for keeping your business running smoothly as it protects against cyber threats that can cause significant financial losses, damage your reputation, and disrupt your operations. As more companies depend on digital tools, the risks from cyber threats have increased. A single risk could cost you a lot of money, damage your reputation, and even bring your operations to a standstill. With cyberattacks becoming more advanced, basic security measures just aren’t enough anymore. To truly protect your business, you need a well-rounded security plan that tackles these modern threats head-on.

In this guide, we will cover seven key steps to help you strengthen your IT security, so you can stay ahead of potential risks and keep your business safe in the digital age.

1. Conduct a Thorough Security Audit

Before you can protect your systems effectively, you need a clear understanding of your current security posture. A thorough security audit helps you uncover hidden vulnerabilities that could put your organization at risk. It’s not just about identifying clear defects but also about understanding the deeper, less visible weaknesses that could be used by attackers.

How to Perform a Comprehensive Security Audit?

You can start by mapping out all your digital assets, including servers, applications, databases, and devices. This inventory will give you a full picture of what you need to protect. Next, assess the security measures you currently have in place for each of these assets. Identify any gaps where your defenses might be weak or outdated.

Use tools like for vulnerability scanning and Metasploit for penetration testing to uncover potential issues that might not be immediately obvious. These tools simulate attacks on your systems to see how well they hold up under pressure.

Don’t overlook the human element. Assess how well your team follows security protocols and identify areas where additional training might be needed. Sometimes, the biggest vulnerabilities are due to human error or lack of awareness. After gathering this information, classify the vulnerabilities based on the risks they pose to your organization. Develop a plan to address the most critical issues first, ensuring that you close the biggest gaps in your defenses. Regular reviews and updates of this plan are important to keep up with the ever-evolving threat landscape.

2. Implement Multi-Factor Authentication (MFA)

Relying only on passwords isn’t enough to keep your systems safe anymore. Cybercriminals have become skilled at stealing or guessing them, so even strong passwords can be compromised. To better protect your systems, it's crucial to add an extra layer of security by implementing Multi-Factor Authentication (MFA).

MFA (Multi-Factor Authentication) strengthens your security by requiring users to verify their identity in multiple ways before accessing your systems, such as using a password plus a verification code sent to their phone. This added layer makes it much harder for unauthorized users to gain access, even if they have a password. To implement MFA, start with the systems that handle sensitive data or critical operations, as these are the most important to protect.

Choose an MFA solution like Google Authenticator, Duo Security, or Authy that works smoothly with your existing technology, and ensure your team understands its importance.

Provide clear instructions and support during the setup to make adoption easier. Regularly monitor and audit MFA use to ensure it’s being properly implemented and is effective in securing your systems.

3. Regularly Update and Patch Systems

Outdated software is an open invitation for cybercriminals. Hackers are constantly scanning for vulnerabilities in software that hasn’t been updated. To keep your defenses strong, you need to regularly update and patch all systems within your organization. This is one of the most basic yet effective ways to protect against cyber threats.

How to Stay on Top of Patching?

Establish a routine for checking and applying updates across all your systems, including operating systems, applications, and even hardware. This routine should be well-documented and adhered to strictly, with designated responsibilities for different team members. Categorize patches for critical systems, particularly those that are exposed to the internet or handle sensitive data. These systems are often the first targets for attackers.

Automate the patching process where possible using tools like WSUS (Windows Server Update Services) or Patch Manager Plus to reduce the risk of human error or delays.

Automation ensures that updates are applied as soon as they’re available, without waiting for manual intervention. For systems that can’t be patched immediately due to compatibility issues, implement temporary measures such as limiting access or increasing monitoring until the patch can be applied. This approach minimizes the window of vulnerability and keeps your systems safer.

Testing Before Deployment

Before testing out patches organization-wide, test them in a controlled environment using tools like TestRail or Jira to ensure they won’t disrupt your operations. This step is important for critical systems where downtime is not an option. Testing allows you to identify and resolve potential issues before they affect your broader infrastructure. Once you’re confident the patch won’t cause issues, deploy it quickly to minimize your exposure to threats. Regularly review and refine your patch management process to keep it efficient and effective.

4. Encrypt Sensitive Data

Encryption is essential to protecting sensitive data. Without it, even if someone breaches your defenses, they could easily access or steal your information. Encryption ensures that your data remains secure, both when stored and when transmitted across networks.

How to Implement Strong Encryption?

Start by identifying all the sensitive data your organization holds, such as customer information, financial records, and intellectual property. This type of data is often the main target for attackers. To protect it, make sure you encrypt the data both when it’s stored (at rest) and when it’s being transmitted across networks (in transit). Use strong encryption standards, like AES-256, which is known for its high level of security and is widely trusted for safeguarding critical information.

Properly managing your encryption keys is important. Store them securely and separately from the encrypted data to prevent unauthorized access. Regularly rotate these keys and update your encryption methods to keep up with technological changes. This ensures your encryption remains effective against new and evolving threats.

To maintain comprehensive encryption, regularly review your practices to ensure all sensitive data is protected. Don’t forget to encrypt your backups as well these can be vulnerable if left unprotected. Encrypting backups ensures that even if they’re accessed by unauthorized individuals, the data remains unreadable. Finally, make sure your encryption strategies comply with relevant regulations like GDPR or HIPAA. This not only protects your data but also keeps your organization compliant, avoiding legal and financial penalties.

5. Strengthen Network Security

Your network is the foundation of your IT infrastructure, and securing it is important to preventing unauthorized access and attacks. As cyber threats become more advanced, focusing on both external threats and internal risks is essential to maintaining a secure network.

How to Protect Your Network?

You can start by segmenting your network into smaller, isolated sections using tools like Cisco ACI or VMware NSX. This limits the potential damage if an attacker breaches one part of your network. By containing the breach, you prevent it from spreading to more important areas of your infrastructure.

Use firewalls and interference detection/prevention systems (IDS/IPS) to monitor and control traffic at key points in your network. These tools help you detect and block malicious activities before they can cause significant harm.

Use secure VPNs for remote access, ensuring that data transmitted over the network is encrypted and that only authorized users can connect. VPNs add an extra layer of security for remote workers, safeguarding your network from external threats. Regularly monitor your network traffic for unusual activity that could indicate an attack. Early detection allows you to respond quickly and minimize potential damage.

Implement network access control (NAC) solutions to enforce security policies on all devices connecting to your network, ensuring that only compliant and authorized devices are allowed. This step is crucial in maintaining the integrity of your network.

Securing Remote Access

With the increase in remote work, securing remote access has become more important than ever. Use strong encryption for all remote connections and require multi-factor authentication. These measures ensure that only verified users can access your network.

Consider using endpoint detection and response (EDR) tools like CrowdStrike Falcon to monitor and secure devices that access your network from outside the office. EDR tools help you maintain visibility and control over all endpoints, reducing the risk of breaches from remote locations

6. Develop a Powerful Incident Response Plan

Even with the best defenses, breaches can happen. How you respond to these incidents can make all the difference in minimizing damage and recovering quickly. A well-developed incident response plan ensures that your team knows exactly what to do when an attack occurs.

How to Build an Effective Incident Response Plan?

Assemble an incident response team that includes members from IT, legal, communications, and senior management. Each member should have clearly defined roles and responsibilities to ensure a coordinated response. Outline the steps to take in the event of a security incident, from detecting and containing the breach to eradicating the threat and recovering systems.

This plan should be detailed and comprehensive, covering every aspect of incident management.

Include communication strategies for informing internal stakeholders and external parties, such as customers, partners, and regulators. Clear communication helps maintain trust and ensures that everyone is informed and on the same page. Conduct regular drills to test the effectiveness of your plan and ensure your team is prepared to act quickly and decisively when an incident occurs. These techniques simulate real-world scenarios, helping your team build confidence and proficiency in handling incidents.

After handling an incident, conduct a thorough review to understand what happened, how it was managed, and what could be improved. This analysis is important for refining your incident response plan and strengthening your overall security posture. Use the lessons learned to prevent similar incidents in the future and to enhance your organization's resilience against cyber threats.

How to Train Your Team Effectively?

Develop a comprehensive training program that goes beyond the basics of cybersecurity. Order the content to the specific roles and responsibilities of your employees. For example, those in finance should focus on safeguarding financial data, while IT staff should learn advanced techniques to identify and lessen threats. This approach ensures that every employee understands how their actions can impact overall security.

Use phishing simulations, to make the training relevant and engaging. These exercises not only help employees recognize potential threats but also provide them with practical experience in responding to security incidents. Regularly update the training material to reflect the latest threats and best practices, ensuring that your team remains alert against new and evolving risks.

Encourage a culture of continuous learning and open communication about security issues. Make it clear that security is everyone’s responsibility, and provide channels for employees to report suspicious activities without fear of retribution. Recognize and reward good security practices to reinforce their importance and motivate others to follow suit.
