Cyber Security Monitoring (5 Key Components)

Continuous Security Monitoring - 5 Key Components | BitSight

Utilizing a continuous cyber security monitoring strategy can give your security team higher visibility into your threat landscape.

To get the most value when investing in continuous monitoring, you first need to understand how data can be compromised.

The three main ways are:

  1. External attacks (i.e., bad actors breaking into your network from the outside)
  2. Insider attacks (i.e., trusted employees or company insiders either willingly or unknowingly becoming the source of data loss, theft, or compromise)
  3. Supply chain or third-party ecosystem attacks (i.e., vendors that have access to your most critical data becoming the source of data loss, theft, or compromise)

Cybersecurity is an often-discussed topic in boardrooms and C-suites around the world.

The alternative to a continuously monitored organization is to be a “compliance-focused” organization—but as we’ve said before, compliance does not equal security.

Therefore, it’s safe to say that having a continuous cyber security monitoring strategy is not just a best practice or a competitive differentiator; it’s simply necessary to operate a successful business.

And while the criticality of continuous security monitoring cannot be understated, the process of building a successful continuous monitoring plan isn’t simple.

We’ve compiled five components you should consider while putting together your continuous security monitoring plan. They are as follows:

  1. Identify the data you want to protect
  2. Create a process for patching security vulnerabilities regularly
  3. Ensure that you’re continuously monitoring all of your endpoints
  4. Create a process for continuously identifying changes in standard user behavior from within your organization
  5. Put continuous security monitoring software in place to monitor your third parties

1. Identify the data you want to protect.

There’s only so much time and resources you can devote to cybersecurity, especially given the budget pressure and increasing number of cyber threats that security teams are facing.

First, decide which data and infrastructure are crucial for your organization to operate efficiently. Identifying this from the outset will help you better articulate your continuous security monitoring strategy.

2. Create a process for patching security vulnerabilities regularly.

Stay aware of vulnerabilities in your network settings or software applications you are using. If you stay on top of your current security posture and what kinds of malware are rampant throughout your industry, you’ll be able to more quickly patch vulnerabilities when they occur.

3. Ensure that you’re continuously monitoring all of your endpoints.

When someone from the outside is trying to gain illicit access to your data, they may, for example, send a spear-phishing email to employees.

This is a great example of why endpoint security—including desktops, laptops, servers, and other things of this nature—is so critical.

If one of your company’s employees was to then click on a spear-phishing link and malware was deployed on your system, you’d be able to address it quickly and securely. Remember: the longer cyber attacks sit on your system, the more likely it is that your data will be compromised.

4. Create a process for continuously identifying changes in standard user behavior from within your organization.

Security measures for potential insider threats are also important to guard with continuous security monitoring. First, you must set a baseline for standard user behavior across your organization. You must understand how most employees usually engage with applications and data in your network.

Can you identify what a typical workday is like for your employees? Or how engaged they are with applications and data in your network? If not, you should begin working on creating metrics and gathering data on these subjects.

Once you’re able to do so, you can better create a process to identify any suspicious changes in behavior that could indicate a potential security threat. Another thing to consider here is whether or not you’ve limited privileges to your most critical data.

5. Put continuous cyber security monitoring software in place to monitor your third parties.

There are many tools and techniques companies today use to continuously monitor how potential security threats get into their network. You can monitor at the firewall or across all of your endpoints to identify malicious code, but what about data that doesn’t sit in your environment?

Has your organization tried to understand their attack surface? It is, of course, also critical to look outside of your organization and use continuous security monitoring for your third parties.

Using a tool like Bitsight Vendor Risk Management (VRM) enables your team to immediately and automatically expose third-party cyber risk during the onboarding process and throughout the vendor lifecycle.

You can also use Bitsight to get an idea of a potential vendor’s cybersecurity posture before you begin working with that company or before it gains access to your sensitive data.

How continuous monitoring enhances security posture

Continuously monitoring your vendors offers several critical advantages compared to the point-in-time nature of annual assessments.

  • Faster identification of threats. By continuously monitoring the risk posed by third-party vendors, CIOs can immediately take action when a vendor vulnerability is detected. Continuous monitoring enables a proactive approach, triggering action based on changes in a vendor's security rating.
  • Customized assessments. While annual assessments treat all vendors as the same, continuous monitoring lets CIOs tailor the cadence of reviews to the risk posed by each vendor. This saves significant time and resources for the vendors you do want to assess, instead of spreading resources to evaluate all vendors.
  • An objective lens. Continuous monitoring using objective data provides context for the self-assessments that vendors complete, allowing CIOs to verify the accuracy of vendors' assessments.
  • Faster onboarding. Continuous monitoring reduces the time and cost required to onboard vendors, allowing organizations to see value from vendors sooner.

In Summary

The point of continuous security monitoring of your information is to protect your organization’s most sensitive data.This is about knowing what that data is, where that data is stored, and who has access to that data is simply imperative. Beyond that, you have to consider what steps to put in place to reduce privileges to that data and how to protect that data wherever it lives.

This is particularly critical when your data lives outside of your organization. By putting a continuous security monitoring plan in place, you will hold your vendors accountable for their actions and make it crystal clear what standards you expect them to uphold.
