Update – February 7, 2018:

Cisco® updated their vulnerability advisory on Monday, February 5, 2018 after identifying “additional attack vectors and features that are affected.” What does this mean? If you patched last week, you may need to patch again. Be sure to read the advisory notice carefully to find out if your environment is at risk.

What is it?

Earlier this week, Cisco revealed that there is a security vulnerability in the Cisco® ASAs, exposing these firewalls to remote attackers. Of course, now we all know about it, as does anyone who may want to exploit this opening. The good news: Cisco has released a critical update to address the issue. The bad news? There is no other workaround, so affected devices must be updated to be secured, and now you’re in a race against anyone who may be trying to take advantage. It’s worth noting that some FirePower devices are affected also, so read the Cisco post in detail to help ensure that you know where your vulnerabilities may lie.

 

What can you do?

Fortunately, if you have SolarWinds® Network Performance Monitor (NPM), our own KMSigma has created a report so you can quickly see if you have vulnerable devices. (For a refresher on implementing user-created reports, see How to export and import reports in the Orion® web console.)

 

Once you’ve identified affected devices, you can use Network Configuration Manager (NCM) to easily schedule, patch, and monitor your ASA devices using the firmware upgrade process. Are you running multi-context ASAs? No problem. The firmware upgrade path supports both single- and multi-context upgrades.

In this industry, it doesn’t take long to realize that discovering vulnerabilities of this nature—and subsequently addressing them—is a standard part of the job description. Having the right tools available can make a notable difference in how long your network is exposed and how much effort is required to remediate issues.

 

Tell us:

Were your devices affected? Have you already updated, and if so, did you use NPM and NCM to do so? Use the comments to tell us how it went. Were you affected but don’t have NPM or NCM?

Keeping a network up and running is a full-time job, sometimes a full-time job for several team members! But it doesn’t have to feel like a fire drill every day. Managing a network shouldn’t be entirely reactive. There are steps you can take and processes you can put in place to help reduce some of the top causes of network outages and minimize any downtime.

 

1. The Problem: Human Element

The dreaded “fat finger.” You’ve heard the stories. You may have done it yourself, or been the one working frantically late into the night or over a weekend to try to recover from someone else’s mistake. If you’re really unlucky (like some poor employee at Amazon® last spring), the repercussions can be massive. No one needs that kind of stress.


The Protection:
First, make sure only the appropriate people have access to make changes. Have an approval system built in. And, since even the best of us can make mistakes, ensure you have a system that allows you to roll back changes just in case.

 

2. The Problem: Security Breaches

Network security is becoming more and more critical every day. People trying to break the system get better, and privacy needs for users gets higher. There are many critical elements to trying to keep your network secure, and it’s important not to miss any. It doesn’t do any good to deadbolt your door when your window is wide open.

The Protection:

Protect your devices from unauthorized changes. Monitor configurations so you can be alerted to any changes, see exactly what was changed, and know what login ID was used to make the change. Also, you should be regularly auditing your device configurations for vulnerabilities. Whether you have custom policies defined for your organization or need to comply with HIPAA, DISA STIG, SOX, or other industry standards, continuously monitoring your devices to help ensure your network stays compliant is one way to help.

 

3. The Problem: Lack of Routine Maintenance

Over time, networks can become messy and disorganized if there aren’t standards in place, increasing both the risk of errors and the time needed to resolve them.

 

The Protection:

Network standardization simplifies and focuses your infrastructure, allowing you to become more disciplined with routines and expectations. Naming conventions, standard MOTD banners, and interface names are just a few things you can do to help troubleshoot and keep a balance within your team and devices, allowing for better management and less human error.

 

4. The Problem: Hardware Failures

It’s not if hardware will fail, but when. Are you ready to make a speedy recovery? When a device unexpectedly goes down, it can have a big impact, depending on which device it is and what redundancies you have in place.

 

The Protection:

Ensure that you can quickly recover devices or bring a replacement online by having device configurations automatically backed up so you can quickly bring new devices online.

 

5. The Problem: Firmware Issues / Faults in the Devices

When you support hundreds of devices, required firmware updates can be tedious, and executing commands over and over increases the risk of error.

 

The Protection:

With network automation, you can easily manage rapid change across complex networks. Bulk deploy configurations to ensure accuracy and speed up deployment times.

 

Increase your uptime and reduce the challenges of keeping your network running smoothly so you can focus on other projects. With SolarWinds® Network Configuration Manager, you can bulk deploy configuration changes or firmware updates, manage approvals, revert to previous configurations, audit for compliance, and run remediation scripts. Take action today to reduce these five causes of network outages.

We just can't have anything nice, now can we?  Oh, well. We knew there would be new vulnerabilities and ransomware attacks in 2018. However, this time hardware is the culprit, and patching is not going to be a cure-all for the situation. Consider yourself warned: expect more slowdowns in 2018.

 

Stop and think about this for a second: as the days progress, we are literally learning how much this new vulnerability impacts us. Anyone who says they have the full solution is not being honest with you or themselves. What I would like to do is help you to see how you can use the tools you likely already have to make you more aware of past, present, and future vulnerabilities and threats. That said, let's move on to the importance of using SolarWinds tools to do just that.

 

SolarWinds® Patch Manager will allow you to update your Windows® machines to their Microsoft® patches. If you are currently using this product, you should already be scheduling and looking for these. I discovered that there can be some issues with third-party Windows antivirus or you might get the BSOD. Read more here, because the awesome chart helps clarify these issues and how to prevent them from happening to you.

 

Further, Patch Manager will allow you to schedule and report on your Windows devices regarding updates. The reporting is key to showcase your compliance and, in this case, start your baseline. Plus, just because you update your devices does not mean you are 100% in the clear. Updating your third-party packages is an added bonus with Patch Manager, a fact that is often overlooked though desperately needed.     

 

SolarWinds® Server & Application Monitoring (SAM) will help you validate your business, yourself, and your vendor support for any degradation that patching may have on your applications. This is something you will want to have in place as soon as possible. It allows you to see any anomalies that may present themselves to your applications after the patching is applied. And because SAM is multi-vendor, you’ll be able to address even broad-scale hardware issues. The avid SAM users among you will likely know even more tricks for using the software, and I encourage you to share your knowledge in the comments to help us all be more aware in terms of application-centric monitoring.

 

SolarWinds® Network Configuration Manager (NCM) comes helps when there are firmware upgrades\updates that need to be applied to impacted network devices. It also helps you to roll these out. There is a compliance reporting function built into NCM that will assist with audits automatically. Remember, this incident is ongoing, which makes NCM’s ability to import very helpful. In fact, you can plug into firmware vulnerability warnings provided by the National Institute of Standards and Technology (NIST). This puts you even further ahead of future vulnerabilities.

 

SolarWinds® Network Performance Monitor (NPM) is all about the baseline. If you have ever been to one of our SWUGs, you have heard me preach endlessly about baselines and their extreme importance. However, I understand that sometimes you need black and white in front of you to truly understand this. The mindset I’m currently following regarding this vulnerability looks something like this:

 

  1. Patched and we have our checkbox
  2. Monitoring our application performances
  3. Ready for updates to needed network devices
  4. Monitoring the common vulnerabilities database
  5. Waiting for any anomaly that may present its ugly face (my favorite)

 

 

We can now show that we have implemented the patching to put a Band Aid® on the issues that could present themselves. However, as I’ve already mentioned, this is not a full fix. A hardware option would be the best solution, but is obviously not available to billions of devices at this time. YOU ARE THE THE FIRST RESPONDER!

 

Using NPM in combination with the other tools that I have outlined allows you to verify the patching and the results. Also, if there are ticks or drops or spikes that do NOT match your current baseline, you can share that solid reporting and documentation with your vendor to work out the possible issue, which makes you part of the solution. Is there anything better than working at the edge of technological advancements to create countermeasures to vulnerabilities? NO. The answer is a solid NO.

 

If you don’t already have it in place, set up threshold alerting and monitoring on critical devices that are housing your applications. That helps ensure that you are alerted to anything out of the ordinary, allowing you to get things back on track. It also shows your team and other departments that you are fully invested in the integrity of application uptime and performance. Also, if you have DevOps, you really need the documentation and baselines to prove that perhaps the performance issue is not the in-house application, but an actual patching issue. That, right there, can save a lot of unneeded cycles through rabbit holes.

 

Please let me know if you have additional ways to protect and help through these beginning stages of 2018 vulnerabilities. The ideas we share could literally help the many of you who act as a one-person army fighting your way to the top!

 

Thank you all for your eyes,

SQL Server Two Ways - SAM AppInsight for SQL and Database Performance Analyzer

 

I read through it again and realized it still resonates in a big way. I’d like to add this foreword and bring it up to speed given some recent changes. SolarWinds® Database Performance Analyzer (DPA) wait-time statistics and resource metrics were recently added to the Performance Analysis view (lovingly known as PerfStack) in the Orion® Platform. I believe this addition gives IT professionals the end-to-end visibility they want. I know we all tend to exist in silos, but that doesn’t mean we don’t want greater upstream and downstream performance metrics.

 

Now you can easily see if your database performance is impacting application response time, and if storage latency is causing longer I/O related database activities. Also, you can view existing dependencies and what relates to what. These customizable dashboards are way cool!

 

If you haven’t had a chance to check it out, you have a couple of ways to do so:

  • If you own just DPA (without any Orion products), you can now download a standalone DPA Integration Module (DPAIM) from your customer portal as part of your existing license. That’s right! It’s free. You will be limited to DPA data only, as there are no other modules running to collect application, server, storage, and network data, etc.
  • If you already have another Orion product and are on the latest release, DPAIM may be installed (it comes with Server and Application Monitor for example), or you can install the DPAIM module from your customer portal on your Orion Platform.
  • If you aren’t ready to commit to a download, you can check out oriondemo.solarwinds.com and try out the Performance Analysis view. This might be a good start to play around with, but remember, it is demo data. Things may not line up exactly. Some of the data might be invented. The best way to get the most out of the PerfStack dashboard would be to look at your own data with it, which is infinitely more interesting!
