Bulletin on Cybersecurity: Rufus AI Security and Performance

Jan 1, 2021 | Security

Recent cybersecurity breaches in the united states have triggered alarm bells about known and unknown threats to our most sensitive data and systems.

So, what’s new?

According to Reuters, The Washington Post, The Wall Street Journal, the malware affected the US Homeland SecurityState, Commerce, and Treasury Departments along with the National Institutes of Health. On Thursday, December 17th, 2020, Politico reported that nuclear programs run by the US Department of Energy and the National Nuclear Security Administration were also targeted. Read more regarding the nuclear energy hack here.

While aware of cyber-attacks’ potential threats, many companies have been complacent in taking meaningful action to secure their enterprise and believe somehow they are protected. More and more, these dreams are becoming worst-case scenario nightmares when suddenly your systems are compromised.


Information indicates that the security breach happened around March 2020. So what also happened around that time? The answer, the Covid 19 pandemic lockdown.

Enterprises have been transitioning from a physical server environment to a virtual or cloud-based server environment for some time. The advantages of the cloud, multi-cloud, and hybrid have many benefits. However, the cloud has added tremendous complexity to the system regarding licensing, network communication, and the secure transfer of data.

During the pandemic lockdown, practically overnight, enterprises switched to a remote workforce. Instead of connecting to the system through office-controlled connections, millions of workers connected from home through not-so-secure home networks, providing an excessive amount of uncontrolled exposure to potential hackers. It is believed that these foreign hackers were able to access enterprise through these networks through poorly secured consumer-grade devices connected to their home networks. Once in, they could create gateways for future attacks.

Many of these gateways go undetected until an attack has been initiated. We believe that many of these open doors still exist in this complex system that has been created.

The difference between a Cybersecurity center and Rufus AI

Cybersecurity centers monitor and send alerts when systems are under attack. Rufus AI alerts attacks and provides manual or automatic solutions to secure your system based on the alert.

Security protocols often compromise performance; for example, an enterprise sets up security firewalls to limit exposure both internally and externally to sensitive data. These firewalls create a delay in performance, for example, reducing the number of transactions per hour from 40k to 25k.

These performance delays cause tremendous financial loss to the enterprise. This is why it is crucial to have a relationship between performance, security, change, and configuration detection.

Why config detection? If systems are compromised, and the technical staff does not detect the breach immediately like what has recently happened, after six months, your information is already compromised, and it becomes challenging to determine all the damage. Why Rufus AI config? Every day Rufus AI takes a snapshot of the applications on your systems and the application signature; by comparing those signatures, Rufus AI can determine if the application code has changed. Together with your configuration management system, we know if this was a vendor update or an illegal update. This way, we monitor attacks from outside to inside and detect hacks on the inside within applications.

Rufus AI is unique because no other vendors are doing total security; they all work from outside to inside.

Technical overview

The Rufus AI solution contains several security and performance steps and will reduce 60% of the helpdesk calls, increase performance without increasing hardware, prevent systems compromised, and total infrastructure management APM application performance management and security.

Vendors detect and alert while Rufus AI detects, alerts, and delivers a manual or automatic solution depending on the severity.

Rufus AI Examples

Example One

Botnets or bots: Botnets are comprised of a series of interconnected computers, sometimes consist of zombie systems or just computers infected with malware.

What does a botnet attack target? These bots are under the attacker’s control and are used to perform an attack against the targeted computer system, network, network device, website, or similar IT environment.

What’s the result of a botnet attack? The attacker uses the bots to bombard the victim’s system, overwhelming its bandwidth and processing capabilities. Disruption is usually the botnet attacker’s goal, often preventing normal working operations or otherwise degrading the victim’s system’s overall service.

What’s scary about botnet attacks? Botnet attacks are notoriously hard to trace due to the many different geographic locations that the other bots can have. There’s no limit to how many systems these attackers can control. One attacker’s bots can number in the hundreds, thousands, or even millions.

How To Prevent?

Different types of filtering offer countermeasures against botnet attacks. Techopedia offers the following examples: 

  • RFC3704 filtering denies traffic from spoofed addresses and helps ensure that traffic is traceable back to its correct source network.
  • Blackhole filtering drops undesirable traffic before it enters a protected network. As soon as a DDoS attack is detected, the Border Gateway Protocol (BGP) host sends routing updates to internet service provider (ISP) routers. This process helps the ISP routers direct all web traffic destined for a victim’s servers onto a null0 interface.

Example Two

Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks: These attacks inundate a system’s resources, overwhelming them and preventing responses to service requests, and significantly reducing the system’s ability to perform. The goal of DoS or DDoS is usually service denial or setting up a different, second attack.

Several different types of DoS and DDoS attacks include the following:

  • Transmission Control Protocol (TCP) synchronize (SYN) flooding or SYN attack:
  • What does a TCP SYN flooding attack target? During a TCP session initialization handshake, the attacker takes advantage of buffer space, exploiting it to flood the target’s system with connection requests.
  • What’s the result of a TCP SYN flooding attack? The targeted system will crash or become unusable due to the overburdened system’s small in-process queue.

How To Prevent?

Rufus AI configures your firewall to halt any inbound SYN packets and then places your servers behind that firewall. Boost the connect queue’s size and reduce the timeout rate for open connections.
