IT hardware is complex and, as a result, can be highly fragile. Even the slightest amount of damage can render it unusable, so you need to protect it.

The fragile nature of IT hardware isn’t your only concern. There is also the cost. While a mouse may not be a bank-breaking  piece of equipment, a PC terminal is. Therefore, it pays to err on the side of caution and ensure your IT equipment is protected. But where exactly should you start? After all, there are so many different types of IT hardware and you need to know which ones to protect and how to achieve this. Let’s take a quick look at what you should be concentrating on.

Protecting Your IT Hardware

There are a number of options when it comes to protecting your IT hardware from damage and the most useful solutions are:

  • Use Surge Protectors: Electrical surges can damage both motherboards and hard drives, so it’s important to use surge protectors. When a surge protector detects that an incoming voltage is too high, it will re-distribute any excess voltage. This protects any devices on that circuit and reduces the risk of them suffering electrical damage.
  • Laptop Cases: Advances in technology mean that laptops are getting lighter and slimmer than ever before. It certainly makes them more portable, but it also opens them up to a world of damage. Protecting your laptop, while it’s in transit, is crucial. The simplest way to achieve this is with a laptop case. Make sure you invest in one which has plenty of padding to minimize the inevitable knocks and bumps it will get as you travel around.
  • Laptop Screen Protectors: It’s more likely that a laptop is going to fall onto the floor than a desktop PC. This means that the risk of screen damage is much higher. And, unfortunately, swapping out a damaged screen is equivalent to the cost of a new laptop. But you can minimize scratches with screen protectors. It’s also possible to buy heavy duty screen guards made from tempered glass to maximize screen protection.
  • Provide Adequate Ventilation: All IT hardware has a tendency to heat up as its workload increases. This is why PCs are designed with internal cooling fans and vents. However, these vents need adequate ventilation to correctly disperse excess heat. If workstations are jammed up against a wall then it’s likely that these vents will be blocked. This can lead to soaring internal temperatures which will literally fry your hard drive. The ideal amount of airspace between a PC and anything else should always be 3 – 4 inches.

A healthy PC is a happy PC and one that will serve your organization well. But to keep your PC healthy you need to carry out regular maintenance.

Take the casing off a PC and you will see that it’s a complex collection of circuitry, wires, boards and fans. All of these parts combine to bring your PC to life. But, with so many different components at play, it’s very easy for one of these to fail. Even the most unassuming, basic component can play a major role in the performance of your PC, so maintaining these is crucial. A PC, as we’ve stated, contains numerous different parts. And that’s only the start. The software contained within the PC also needs maintaining to prevent system errors and hardware damage.

It may sound as though you have a mountain to climb when it comes to PC maintenance, but it’s actually very easy.

Keeping Your PC Healthy

Thankfully, there are a number of simple and quick practices you can carry out to maximize the health of your PC. These are a mixture of software and hardware tips which include:

  • Shut Down Correctly: The end of the working day often signifies a rush to leave and the process of shutting a PC down correctly often suffers. Hitting the power button may be quicker, but it risks a number of problems. Firstly, there’s the risk that unsaved work will be lost and, secondly, the shutdown process allows the disk drives and RAM to power down correctly. Modern PCs may be mostly immune to power spikes, but they’re not completely So, take your time and shut down correctly. 
  • Clean Your Keyboard: A keyboard remains an essential part of any PC and allows you to complete almost every necessary task. That’s why a failed keyboard will instantly affect your productivity. It may be that a single key doesn’t work or it may be that the entire device is damaged. Either way, it’s vital that you regularly clean the keyboard. The best way to do this is by turning the keyboard upside down and shaking it before using a can of compressed air to blast anything else out. Finally, use an alcohol-based wipe to fully clean the surface. 
  • Organize Your Cables: Even the most modern PCs require a number of cables to connect all the required components. The sheer number of cables involved can soon become jumbled. And this only becomes more complicated the more additions you make to your system. If these cables are not organized correctly then your PC will be left vulnerable to damage. Not only is there the risk of entire systems getting pulled on the floor, but there’s the risk of electrocution. Avoid this by detangling cables and using cable ties to gather them together. 
  • Always Update: It’s important that all updates and patches are installed as soon as they are available. The process may feel time consuming, but the majority of these procedures will take place in the background with minimal impact on performance. And, by installing these upgrades, you will maximize your PCs performance and protect it from any software vulnerabilities.

Its name is Shodan and it could just revolutionize your device security.

Let’s take a look at what it is and how Shodan can keep the IoT secure.

What is Shodan?

Shodan is, in its simplest terms, a search engine for IoT devices. It’s similar to Google, but rather than searching for news on your favorite TV shows, you can use it find IoT devices. As long as a device is connected to the internet, Shodan should be able to find and identify it. And this applies to any IoT device be it a printer, security camera or refrigerator.

How Does Shodan Work?

The part of the internet that the IoT connects to is usually considered invisible, but all it takes is the right algorithm to analyze it. And this is what Shodan does. The overall mechanics of Shodan’s algorithm is complex, but here’s a breakdown of how it works:

  • Creates random IPv4 addresses which are used to identity network interfaces on a machine
  • Scans the internet for a real time list of connected IoT devices
  • Scans each device by checking a selection of available ports
  • Analyzes each port for a unique IPv4 address
  • Grabs a selection of metadata from the device which includes: usernames, passwords, geographical location and IP addresses

And all of this information can be displayed in the search results on Shodan.

Is Shodan a help or a Hindrance?

The amount of sensitive data that Shodan can expose is worrying. The last thing you want is for your usernames and passwords to be compromised. This could lead to grave consequences for your security. But is Shodan as scary as it sounds? Well, the truth is that it can actually enhance your IoT security.

Shodan is now a popular tool for security professionals to evaluate their IoT devices. And it’s most commonly used in the following ways:

  • Detecting Vulnerabilities: Shodan has a range of filters available that you can use to identify potential vulnerabilities in your IoT devices. This could include the use of default login credentials (these are the only login details that Shodan exposes) or which ports are currently open. By identifying these vulnerabilities with Shodan you can rectify them.
  • Track Exploits: Hackers are industrious characters and relish the challenge of identifying exploits. And the result is that IoT devices are constantly in their targets. Thankfully, Shodan is on hand to help. It does this by collecting together all known exploits for IoT devices and making them available. All a user has to do is use the Shodan search engine to search for specific terms and uncover any known exploits.

Getting to grips with problems relating to your computer network can be a frustrating affair, but it’s one which is likely to happen on a daily basis.

Computer networks are, after all, highly complex systems that comprise various components and are in use by multiple users. These structures may bring many benefits, but they can also be a recipe for disaster. And, if your network fails or experiences any issues, then your organization’s productivity is going to be affected.

Your main objective, with your computer network, should be to keep it online and functioning correctly. But you can only do this if you know what the most common computer network problems are, so let’s take a look:

  • Slow Connectivity: If there’s one thing that frustrates an employee then it’s slow connectivity over a network. PCs can grind to a halt and even the simplest task can take an age to complete. It’s often caused by large file transfers, so a limit should be put in place on the size that is permitted e.g. no email attachments that total more than 20mb as a standard rule. Sometimes this lag can also be caused by faulty network cards, so it’s important to investigate this possibility. 
  • IP Conflicts: Each PC on your network should have a unique IP address such as 209.85.255.255, but sometimes two PCs can be assigned the same IP address. And this can create major connectivity issues for both parties. Sometimes these conflicts will work themselves out, but you can help speed up the process. Restarting the router is the simplest approach as it should assign new IP addresses to every PC on the network. 
  • Unable to Connect to Local Printer: Printers on a network tend to be shared by multiple users, but occasionally an error can arise that leaves people unable to access the printer. This problem is often caused by a sharing issue whereby different security settings between PCs and the printers fail to agree with each other. When this occurs it’s recommended that you check firewall settings and that your Windows network adapters have printer sharing enabled. 

  • Faulty Cables: A computer network relies on cables to facilitate its connectivity. And when just one cable fails it can have massive implications for your network. However, it’s easy to overlook cables as the source of network issues. People tend to concentrate on software and hardware troubleshooting first. Nonetheless, investigating the condition of cables in the affected network area is vital. Cables can easily become dislodged or damaged, so sometimes the fix can be as simple as plugging them back in or replacing. 
  • Weak Wi-Fi Signal: If you rely on wireless connections in your organization then you will be well aware of the issues caused a weak signal. This can often be caused by environmental issues such as the presence of a microwave or even the layout of an office. It’s important to eliminate these factors to identify the cause of the fault. Alternatively the connection issues could be caused by out-dated firmware, so make sure all updates are installed.
