Windows is one of the most popular operating systems around and, as it’s a Microsoft product, you would like to think it’s safe. But this isn’t quite true.

As part of their January 2022 ‘Patch Tuesday’ report, Microsoft announced that 97 new security vulnerabilities had been discovered across its range of operating systems. And with an estimated 1 billion Windows PCs in use across the globe, this is very concerning. Any operating system, of course, is a highly complex piece of software. The sheer amount of coding required, to deliver high quality functionality, means that mistakes are inevitable. And then there are the hackers, individuals who are determined to find new and innovative ways to breach Windows.

What Were the Vulnerabilities?

Nine of the reported vulnerabilities were classed as critical by Microsoft, with the remaining 88 being classed as significant threats. Technical details are yet to be released, but it’s known that some of the critical vulnerabilities were associated with Microsoft Exchange Servers and the HTTP Protocol Stack. And, in particular, the HTTP Protocol Stack vulnerabilitiy is one which would allow hackers to allow remote code execution i.e. taking control of an affected PC from a remote connection.

Six of the vulnerabilities discovered have also been categorized as zero-day vulnerabilties. These affect a range of Windows background processes and, as they are classed as zero-day, it’s believed that they were known to hackers before Microsoft’s announcement. Collectively, the 97 vulnerabilities are believed to have impacted the security of major Microsoft applications including Excel, Word, Edge, Windows Defender and all manner of network tools. As a result, it’s believed that users of Windows 7, Windows 8, Windows 10, Windows 11, Windows Server 2019 and even Windows Server 2022 are all at risk.

How Can Windows Users Stay Safe?

Naturally, any user of Windows is likely to be very concerned after reading the above. But the good news is that Microsoft’s January 2022 patch addresses all of these vulnerabilities. Installing it, therefore, should be the number one priority for any PCs running Windows. And that will be nearly all of them. Unfortunately, for those running Windows Server 2019 and Server 2022, this patch was withdrawn due to bugs it was generating in these environments. Users of these operating systems should remain extra vigilant and ensure that automatic Windows updates are in place.

Final Thoughts

The last few months have been relatively poor for Microsoft when it comes to patching vulnerabilities. In September 2021, it was revealed that their patch for the ‘PrintNightmare’ flaw contained bugs which negatively affected numerous printers. And, now, it appears to be history repeating itself with Windows Server users left vulnerable to both security risks and buggy updates. These issues will, no doubt, be rectified quickly but, as ever, time is of the essence when it comes to PC security. Ultimately, installing each and every security update remains the very best practice for protecting your IT devices.

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.

5 Things to Consider When Upgrading Your Servers

Your server is the backbone of your organization’s IT functionality, but what do you need to consider when it’s time to upgrade?

Purchasing and installing a new server is a massive move for any organization. Install the best server for your needs and your productivity should skyrocket. Choose one that doesn’t quite fit with your business and it will seriously harm the way you’re able to operate. Therefore, choosing the correct server is important if you value your organization’s future.

Moving forward, though, isn’t always straightforward due to the complexity of such an upgrade. To help simplify matters, we’re going to share five things to consider when upgrading your servers.

  1. The Right Performance

First and foremost, you have to make sure that any potential new server is able to meet the needs of your organization’s IT needs. The main reason that an organization looks to upgrade is because the current technology isn’t able to fulfill their existing needs. Consulting with various department heads and IT professionals is essential to gauge the necessary requirements, so start by compiling this information and work from there.

  1. Is Integration Possible?

You’ve more than likely got an existing server in place, but upgrading doesn’t mean that you need to chuck your old one out with the trash. In fact, it’s possible that you’ll be able to integrate vast sections of your existing server into your new server. Not only does this potentially save you costs on new technology, but it also provides a level of consistency in terms of staff knowledge on the existing technology.

  1. Costs?

Performance, of course, is paramount, but price is equally important as all organizations work to a strict budget. Once you understand your performance needs, the next step is to evaluate which available servers meet this most closely. Technology, after all, can be costly, so you shouldn’t be paying for any technology that won’t be of use to your organization’s output.

  1. Factor in Maintenance

A brand new server is fantastic, but even the most up to date technology needs to be maintained. Any length of downtime is disastrous for any organization which understands the basics of productivity, so the shrewdest move with servers is to ensure that some form of maintenance cover is put in place. Often, there will be a warranty included with new technology, but this will always have an expiry date, so make sure you start asking about extended warranty options from an early stage.

  1. Future Upgrades?

It may seem counter-intuitive to consider future scalability as you upgrade, but looking to the future is vital when it comes to working with IT technology. The rapid pace at which technology expands means that you may need to consider growing your server a lot sooner than you expected. Discussing expansion options is crucial to safeguard against being lumbered with huge costs in the future when your existing technology is unable to expand further to keep pace.

The computer servers that support your business are the backbone that keeps your organization productive, but how do you keep your business servers safe?

Every week seems to bring a new security threat and you can rest assured that the number and ferocity of these attacks isn’t going to subside anytime soon. Your business servers, of course, contain untold amounts of sensitive data that could be used to harm not only your business, but also your customers. Therefore, keeping on top of your servers’ security is paramount in protecting your data from the all too real threat of hackers.

To help you stabilize and improve the security of your business servers, we’ve put together a plan of recommendations to help you meet your security objectives.

Run an Antivirus. Regularly.

Viruses can spread from file to file very quickly and, before you know it, your entire server can become compromised. However, a piece of antivirus software can prevent the majority of existing viruses taking hold of your servers. Quarantining infected or suspicious files allows you to analyze anything that is flagged as potentially dangerous, so installing antivirus software really is a prerequisite of good security practices. And, to really maximize its effectiveness, run it regularly as an infection could occur at any point during in the day.

Update Your Server Software

Many pieces of malware work by exploiting security vulnerabilities in software such as Petya and NotPetya, but these vulnerabilities could be easily avoided by patching. Installing patches, though, can feel like a tiresome task, particularly when your organization needs to stay productive. To put things into perspective you need to weigh up the minimal downtime of installing updates against the havoc caused by an infected server. The answer’s pretty obvious, right? Install those patches and install them immediately.

Educate Your Staff on Security Threats

Your staff are the first line of defense against any cyber-attacks on your organization, so it’s crucial that they’re trained in what to look for and what to do in the case of an attack. Naturally, they’re not going to be partitioning infected servers or installing critical updates, but they can do the very basics. And this can be as simple as good password practices or understanding how to identify a phishing email.

Backup Your Data

Ransomware has become a major issue for businesses in the last couple of years and, in many cases, paying the ransom doesn’t even guarantee the release of your files. And this is why it’s vital that your organization embraces backups to help safeguard your data in the event of a ransomware attack. Backups have been a cornerstone of IT security since the dawn of the digital age and their importance should never be underestimated.

Keep Web Browsing Separate

The internet is a portal to untold amounts of information, but it’s also a gateway to untold security threats. And this is the last thing you want your business server exposed to. Providing internet access through a separate server (to your main server), therefore, allows you to minimize the risk to your most important data.

If you want your business to be successful and allow your team to collaborate with ease then you need a great PC server, but how do you know which is right?

You’re almost certainly aware that a server is an essential business purchase in the digital age, but do you know what a server actually does? Usually the preserve of IT professionals, servers are dedicated computers that allow you to run hardware, share resources and connect people within your organization. So, as you can tell, they’re crucial for your business to operate and boost your staff’s productivity.

Choosing the best server for your business, however, is a little more complicated due to the vast range of servers available. Naturally, this choice ensures there’s a server for every organization’s needs, but the technical specs and jargon can seem a little bewildering. Thankfully, I’m going to break this jargon down into something more digestible to help you make the right choice.

What Types of Servers are Available?

There are two types of servers most commonly seen in businesses:

  • Rack Mounted Servers: Installed within a framework known as a rack, a rack server is a computer dedicated for use as a server. Due to the racking system in place, rack servers can save you valuable space by stacking one server above the other. Rack servers also bring much more simplicity when it comes to connecting cables between individual components.
  • Tower Servers: Housed within a single, upright cabinet, a tower server contains a computer which is intended to be used as a server. These types of servers allow easier cooling of individual components and offer a scalability which allows you to constantly add new servers to your network.

 Which Operating System is Best? 

When it comes to servers, the very best option you can choose to power them is Windows Server. It may feel as though Windows Server is ubiquitous in modern computing and among your rivals, but this is for one simple reason: it’s incredibly effective.

In use, in its earliest incarnation, since 2003, Windows Server is the industry standard, so there’s not only a vast range of options contained within its shell, but there’s also an amazing amount of support available to tackle virtually any issue. There are, of course, alternative options (mostly open source software), but the support for these systems is less prevalent.

How Do You Determine Storage and Memory?

One of the most important needs of a good server is adequate storage and memory. Therefore, calculating the needs of your organization’s computer activity is crucial. Every organization is different, so you will need to analyze your digital operations closely. For example, if you run a client database which requires 1TB storage and 4GB memory then your server needs to have at least that amount of storage and memory. Chances are that your storage and memory needs will increase over time, so it’s recommended that you overbuy in terms of storage and memory to accommodate any future demands.

These are the very basics of servers, but if you can get them right then you’re laying down a fantastic foundation to help power your organization’s networks.
