Seek Out and Remove End-Of-Life Components

Posted on December 5, 2022 by Brent Huston

Just a quick reminder, at some point during each quarter, it is a good idea to enact a process to seek out and remove any end-of-life products in your environment. This is not only a best practice but a significant risk reduction measure as well. Make it an ongoing periodic process, and you’ve got a powerful weapon against threats and emerging issues stemming from end-of-life hardware, firmware, and software in your networks.

How to Search for End-Of-Life Products In Your Environment

The first step is to identify the devices, applications, and firmware that are no longer supported by their vendors. You can do this manually or with a tool. The next step is to determine which of those devices have been deployed in your network. Once you know where they are, you need to find them. There are several ways to search for these devices:

Use Network Inventory Tools

Network inventory tools such as Nmap and Nessus will allow you to scan your entire network to locate all of the devices on your network. These tools will also tell you what operating systems and versions of software/firmware are running on the device. If you’re using a vendor-specific tool, you’ll be able to see if there are any known vulnerabilities associated with the product in many cases.

Talk to Device and Application Owners

If you don’t already have a relationship with the owners of the devices and applications, then you should start building one now. It’s important to get to know the people who own the devices and applications so that you can ask questions about how they use the devices and applications. You may even want to consider getting an end-of-life security policy together for the organization so that you can make sure everyone understands the risks of end-of-life components.

Once you have discussed the issues with the owner, remove the component if possible. Otherwise, add it to a list of components to look for workarounds or replacements. Many organizations that can’t manage to replace an end-of-life component either place it in a low trust network zone, front-end it with firewalls or ACLs, and increase monitoring and detection of the assets involved. Of course, the component should be reviewed quarterly until it can be removed from service.

Doing this process every quarter will increase your networks’ overall stability and trust worthiness, plus reduce risk and management headaches. It’s well worth your time and an effective part of an overall risk management strategy.

How Do I Know If My Company Needs a Risk Management Policy?

Posted on May 16, 2022 by Brent Huston

Risk management policies protect companies against financial losses due to various risks. These risks include legal issues, employee misconduct, environmental hazards, etc.

A company may implement a risk management policy to minimize these risks. However, several questions should be asked before implementing such a policy.

What Are the Risks That Could Lead to Financial Losses?

Many types of risks can lead to financial losses. Some examples include:

• Legal issues

• Employee misconduct

• Environmental hazards

• Product liability

• Cybersecurity threats

• Data breaches

• Other

It is important to understand what type of risk your company faces. For example, if your company sells products online, you will face cyber security risks.

Are There Any Existing Policies?

Before deciding whether or not to adopt a risk management policy, it is important to determine whether any existing policies cover the risks your company faces.

For example, if your company has an insurance policy, then you may not need to implement a separate risk management policy.

However, if your company does not have an insurance policy, then it is necessary to consider implementing a risk management policy.

Is Implementing a New Policy Worth It?

Once you know what type of risks your company faces, it is time to decide whether or not to implement a risk management plan.

Some companies feel that they do not need a risk management plan because their current policies already address their risks. However, this decision should be made carefully.

If your company does not have a formal risk management policy, then it is possible that some of the risks your company faces could go unaddressed. This means that the risks could become more significant problems down the line.

In addition, if your company decides to implement a risk management program, it is crucial to ensure that the program covers all the risks your company faces, including those currently unaddressed.

Do Your Employees Understand What Is Being Done?

When implementing a risk management plan, it is vital to ensure employees understand what is being done.

This includes explaining why the risk management plan was implemented, how the plan works, and what steps must be taken to comply.

The goal here is to ensure that employees understand your company’s risks and how the risk management plan helps mitigate them.

Will the Plan Be Cost-Effective?

Finally, it is essential to evaluate whether or not the risk management plan will be cost-effective.

Cost-effectiveness refers to the amount of money saved compared to the costs incurred.

For example, suppose your company spends $1 million per year to insure its assets. In addition, suppose that the risk management plan saves $500,000 per year. Then, the risk management plan would be considered cost-effective if it saves $500,000 annually.

In this case, the risk management plan is cost-effective because it saves $500,00 annually.

However, if the risk management plan only saves $100,000 per year, then the plan is not cost-effective.

In Conclusion

As discussed above, there are many reasons to implement a risk management strategy.

These strategies can help your company avoid potential financial losses caused by certain risks.

In addition, implementing a risk management plan can make your company more efficient and productive.
