Understanding CPU Spikes and P J Networks Monitoring Service

There is no doubt that in today’s digital landscape, the importance of firewalls to secure networks and their communications cannot be overstated. Firewalls, however, are systems that can be strained by performance such as CPU spikes. The knowledge about CPU spike causes and effects can mean all the maintenance to provide a safe, efficient network. In this blog, we would discuss the reasons of high CPU utilization in firewalls and why it is risky to ignore. And further how P J Networks monitoring service helps us discover those issues with mitigation tips. We will also be showing a case study of how our service has helped protect your site and tips on optimising your firewall with P J Networks.

What Causes CPU spikes in Firewalls?

When an abrupt hike of CPU usage happens, this is called a Central Processing Unit (CPU) spike and it can severely impair the performance of your firewall. Many reasons can be responsible for CPU spikes on firewalls:

High Traffic Volume

• Packet Inspection: Firewalls inspect all inbound and outbound packets to ensure that they comply with security policies. High traffic Volume, for example: A sudden spike in CPU usage due to a huge increase of network traffic.
• Connection Flooding: Similar to the Massiveness connection, DDoS can cause so many connections that spike on a CPU of firewall.

Configuration Issues

• Improper Rules: Simply put, too many or wrong structured firewall rules will make inefficient packet processing.
• Logging and Reporting: Aggressive logging can use a fair amount of CPU.

Firmware/Software Bugs

• Software Glitches: Malfunctions in the firewall firmware or software can consume CPU cycles unnecessarily.

Malware

• Botnets & Viruses: Malware can infect the firewall system and leverage its resources to generate an attack, causing CPU spikes.

These reasons help in diagnosing and solving the root issues leading to a CPU spikes.

Why You Can’t Ignore High CPU Usage

There are dire consequences to ignoring high CPU usage in firewalls:

Performance Degradation

• Slow Network Response: When CPU utilization gets high it makes your network processing slower, which can cause delays.
• Dropped Packets: High CPU utilization in turn may lead into a situation where packets are dropped from the queue and communication breaks down.

Increased Vulnerability

• Security Breach: Firewalls loaded with excess traffic can cause them to overlook inspection of packets and harmful data may make it past.
• DDoS: High CPU usage means it is more likely that a firewall can be overloaded and used in DDoS attacks.

Operational Disruptions

• Service Downtime: Continuous high CPU usage can cause firewalls to crash, causing the network outage.
• Administrative Overhead: Great, we get to spend time troubleshooting and resolving issues caused by high CPU use on our servers.

These risks have shown how crucial it is to monitor your network continuously and act on any impending threats before they can impact not only the performance but also the security of a network.

How P J Networks Monitors and Alerts on CPU Spikes

At P J Networks, we provide a complete monitoring solution that will help businesses to identify and react promptly against CPU spikes. This is how our service shines:

Real-Time Monitoring

• Continuous Oversight: Our observation software program analyzes CPU utilization time and again in real-time.
• Threshold-based Alerts: Customizable thresholds which trigger alerts when CPU utilization surpasses predefined exhaustion, helps in immediate corrective measures.

Detailed Reporting

• Usage Trends: Periodic reports can reveal usage patterns, making problems easier to identify earlier.
• Performance Metrics: Provide detailed metrics to review the firewall performance.

Proactive Maintenance

• Firmware Updates: Automatic updates will keep your firewall software healthy and running the most recent version of security.
• Configuration Optimization: We conduct periodic scans to fine-tune firewall rules and settings, enabling maximum efficiency.

Incident Response

• Alert Management: Proactive alerting is sent to our security operations center (SOC) for immediate identification and response.
• Automated Actions: Predefined actions that can mitigate risks, for example block traffic from suspicious sources.

The last thing you should be worrying for is your firewall performance, our monitoring service ensures that we keep all eyes trained on it.

Case Study

This particular mid-sized e-commerce company found their firewall reaching up to 60% CPU usage during occasional DDoS attacks. They signed up for P J Networks monitoring service, this is where we assisted:

Problem

• High CPU usage due to firewall was overwhelmed by frequent DDoS attacks causing network outages.

Solution

• Real-Time Alerts: As soon as a CPU spike was detected by our monitoring system, it alerted the IT team.
• DDoS Mitigation: DDoS attacks are partially filtered by automated scripts to reduce the negative impact.
• Optimization: We examined and optimized the configuration of firewalls so that legitimate connections could be processed more efficiently.

Results

• The company experienced a marked increase in the stability of its networks, with CPU spikes being reduced by 70 per cent.
• There was no downtime experienced in the following DDoS attacks, thereby offering uninterrupted services to their customers.

This study shows just some of the real-world value to be had when you actively monitor and optimize your firewall.
