With modern threats becoming more creative and more dangerous, it’s important that businesses implement proactive cybersecurity measures to stay one step ahead of the game.

Read on to learn more about what a proactive cybersecurity measure is, why it's better to stay proactive rather than be reactive, and some examples of the tools, software, and policies that make for a more proactive approach to cybersecurity.

Proactive Cybersecurity vs. Reactive Cybersecurity

Proactive cybersecurity measures are steps taken by businesses to prevent incoming attacks from happening or causing damage. This means taking steps and implementing technology that helps to identify threats before they execute or can get into your network, taking steps to keep your software and tools fully updated, and implementing security across your entire organization.

the difference between reactive and proactive cybersecurity measures

Proactivity in cybersecurity is more than just plugging in software. It’s a mindset and a dedication to consistent evaluation of your security environment and understanding the possible threats organization-wide.

Reactive cybersecurity measures, on the other hand, are built only to react to attacks after they’ve already happened. This means patching vulnerabilities after they’ve been exposed and abused, updating firewalls and antivirus software after it’s already been breached, and taking measures to prevent repeat attacks.

Do You Need Both?

While there is some merit in strengthening your cybersecurity posture after an attack, such as ensuring a repeat attack won’t occur, it’s always a good idea to focus more on preventing attacks from ever occurring in the first place. So, while you could have some reactive cybersecurity measures alongside your proactive ones, you should never rely solely on them.

Proactive cybersecurity measures should be the focus and foundation of your business’ cybersecurity posture.

Proactive Cybersecurity Measures

When it comes to those proactive security measures, they come in a lot of flavors that hit upon different aspects of cybersecurity and different potentially vulnerable spots in your business network. Here are some examples of proactive cybersecurity measures that modern businesses need to stay secure:

- Employee Awareness Training: People are often your first line of defense. It’s critical that you give them the training they need to be aware of and understand cyberthreats that will come knocking on their door through malicious websites, phishing messages, and other social engineering attacks. Cybercriminals tend to view people as a weak point in business security, but they don’t have to be.

- Updated Next-Gen Antivirus: To defend against modern threats, you need modern tools that go beyond the capabilities of the past. Legacy antivirus software just doesn’t cut it anymore because not only has it been figured out by cybercriminals; but it also simply lacks the features that are required for proactive cybersecurity.

- Software Patches and Updates: When developers become aware of potential vulnerabilities in security software, they release patches to secure them. For businesses, it’s important to keep all your security software fully updated with the latest patches to keep cybercriminals from abusing these known weaknesses.

- Firewalls: Similarly to antivirus software, businesses need new-school firewalls that can recognize and filter our modern threats.

- Data Encryption: Encrypting data helps businesses keep their data secure, even if it does fall into the wrong hands by ensuring only those with access can decipher it.

- Data Segmentation: If an attack occurs, data segmentation is a proactive step that businesses can take to prevent cybercriminals from accessing everything through one vulnerability. Layered protection keeps segmented data secure even if one segment becomes exposed.

- Network Monitoring: Modern network monitoring solutions can implement AI and machine learning technology to adapt and learn about new threats and how to spot them. This ability helps protect businesses from evolving threats.

- Identity and Access Controls: It’s important to restrict access to important systems and information to just those that absolutely need it to do their jobs. Enforcing the principle of least privilege is a step that businesses can take to ensure nobody is misusing credentials to access information they don’t need, leaving it vulnerable to theft.

- Endpoint Protection and Edge Security: It’s important to cover all your angles when fighting cybercriminals. Endpoint protection and edge security provide additional layers of security by protecting your business from being compromised by the devices on the fringe of your network.

In Conclusion

Implementing proactive cybersecurity strategies is the best way to stay ahead of modern cybercriminals and prepare your business for anything that can be thrown at it. With the appropriate and proactive-focused tools and policies in place, you can stay secure in a changing threat landscape.
