Posted by & filed under IT Support. Protected by Copyscape

Computer security threats that permeate the digital world have made every enterprise’s network unsafe. With the ability to annoy, harm and steal, these threats masterfully disguise their way into a system by manipulating the users.

Businesses are not safe, for a single security breach can result in the compromise of sensitive information, leading to loss of business critical data and heavy expenses that are incurred in the process of recovery and restoration.

To counter the computer security threats, organizations are constantly involved in the process of erecting, implementing and updating a robust security infrastructure. And, it all starts with equipping oneself with the basic knowledge about the threats that endanger a computer system. For, if you know what you are up against, you can strategize a well rounded and comprehensive mitigating plan.

Welcome to the weekly edition of “Know Your Row” (hyperlink to blog titled: “Find Out About the Computer Security Threats You Haven’t Protected Against”) blogging series, where today, we will talk about:

The 4 most common computer security threats

The information provided in the blog post, aims to help you—our readers, in identifying the common computer security threats and assist you to structure a security program based on the acquired information.


Computer Security Threat #1: Viruses

Viruses are, and have been the most common and ubiquitous nemesis to computer security, carrying high level of danger. Out of the 24 million malware attacks that have affected the US computers in last two years, 57 percent of them were in the form of viruses.

A virus is a computer program that replicates itself without the user’s permission, spreading and damaging the files non-stop. It can be transferred through a downloaded file or through an infected media disk, presenting a list of endless ways for the malicious actor to exploit your system.


What You Can Do?

In order to prevent and remove virus infiltrations, you can try the following list of solutions:

  • Make sure your OS is fully updated.
  • Make sure you have a comprehensive anti-virus suite installed on your machine that is equipped to handle latest and old malicious software versions.
  • Run regular scans to ensure that your system is operating at optimum health levels.
  • Scan every file before downloading, and every media disk before mounting on the system.

Computer Security Threat #2: Keystroke Logging

Keystroke logging is an activity of recording the keyboard taps, and sending over the recorded information discreetly to a remote party. It is executed through a software program, called keylogger, which installs itself onto a machine, transferred via an infected plug-in device or through the internet. Since the information being sent consumes minimal of bandwidth, it is almost impossible to monitor the breach.

Information like credit card account numbers and important passwords, typed during the process of accessing an account are often at risk, communicated via a keylogger.


What You Can Do?

You can try the following solutions to counter the threats posed by keystroke logging:

  • You can install a latest version of a firewall on your system. This way, whenever the software program tries to communicate with the remote party, in order to send the captured information, the firewall will alert you of a possible exchange.
  • Another solution is to install a password manager. This way the sensitive information can be automatically entered while trying to access an account, without having to tap the keystrokes.


Computer Security Threat #3: Mousetrapping

You open the browser, and automatically get directed to a website’s homepage, which you never intended to visit.

Fine, you gasp!

You click on the address box, and type:


You again get redirected to the same website.

You try again, and you end up on the same website – once again!

Bad news, your system has been exposed to a Mousetrapping malware.

It is a software that confines a system’s web browser within a particular website. You cannot navigate any other page, you cannot visit another website. You are just trapped there. The whole business workflow comes to a still, especially if the operations are heavily dependent on the medium of internet.


What You Can Do?

You can try following solutions and strategies to overcome the inconvenience caused by Mousetrapping malware:

  • Try disabling the JavaScript functionality, by accessing the option from the web browser’s setting.
  • Install an anti-virus software on your computer, updated to the latest version, so as to effectively identify and eliminate all Mousetrapping malware files from your system.

Computer Security Threat #4: Ransomware

If you have been recently following the daily prime time news, chances are that you may have heard about the global cyberattack, WannaCry, a digital heist that affected the computer systems of major and minor organizations across the globe. The first signs of the attack were spotted on May 12, 2017.

It was a malware—a ransomware, which encrypted the files and demanded, bit coin in return for the files to be decrypted back.

And, this was not the first case of a ransomware attack reported in the history of internet. The malware variant has become quite a common computer security threat, believed to have been infecting four thousand machines daily, since the start of 2016.


What You Can Do?

Once the ransomware infects a machine, it is almost impossible to make your way through without paying the demanded ransom. As such, organizations have to focus on shaping up preventive strategies, some of which are as follows:

  • Enabling robust spam filters to avoid being exploited by email phishing, a common mode of ransomware infiltration.
  • Installing and configuring firewalls to restrict access to malicious IP addresses.
  • Disabling macro scripts from the office files that are transmitted via email.
  • Create backup of important files, so that even if your files get encrypted by a ransomware, you can restore the system back to normal functionality.
  • Keep your OS software and antivirus programs updated.


By shaping up a security program that addresses the aforementioned computer security concerns along with other threats, you can enact a robust and comprehensive strategy that will ensure maximum safety of your important digital assets.
