Data will always be one of the cornerstones of your business. But keeping this data secure in the 21st century is a big ask. So, how do you protect it?

A staggering amount of data is created every single day and your business will contribute to this with each order placed, every service request logged and all the mailing lists you create. Data such as this is sensitive and needs to be protected. If personal details are compromised then they can be used for fraudulent purposes. Your customers need to trust your organization to handle and protect their data correctly. But in a world full of hackers, malware and social engineering it can feel like an uphill struggle.

However, you can make a significant difference to your data protection. And it doesn’t have to be difficult. In fact, you can elevate the security of your data quickly and effectively. All you have to do is follow our 7 tips for keeping your sensitive data secure.

  1. Use Cloud Storage

Individual PCs can become compromised by security breaches. And this means that the data stored on this hardware is up for grabs. But if this data is stored remotely it’s securer and less likely to be stolen. The perfect way to achieve this is by investing in remote cloud storage.

  1. Never Display Passwords

Passwords should never be displayed e.g. written on a Post-It note stuck to your monitor. Hackers don’t have to be external figures, they can easily be an internal threat. Therefore, create passwords which you can remember easily and don’t need to have visible reminders for.

  1. Make Sure Deleted Files are Overwritten

A deleted file isn’t necessarily deleted. And a hacker who knows what they’re doing can easily retrieve those files you thought were deleted for all eternity. But if these deleted files are overwritten enough times then you can make it impossible to retrieve them from your hard drive.

  1. Always Encrypt USB Sticks

USB sticks are useful for carrying around large amounts of data in a small space, but their small size means they’re easy to lose. Therefore, you should always ensure that data on these devices is encrypted and password protected.

  1. Install Anti-Malware Protection

You can never take enough precautions when it comes to data security, so anti-malware software should always form part of your strategy. Malware operates stealthily and can steal your data at a rapid pace. But with anti-malware protection in place you can reduce the risk of malware getting a foothold in your system.

  1. Always Install Updates

PC software and hardware is prone to security vulnerabilities. And these vulnerabilities give hackers the opportunity to access your systems and your data. Installing all updates at the earliest opportunity helps you to avoid having your systems and data compromised.

  1. Destroy Old Hard Drives

Technology advances at a rapid pace and PC hardware can soon become obsolete in the face of newer, faster technology. Hard drives are a case in point. But you need to make sure old hard drives are disposed of correctly. They contain a lot of data, so need to be thoroughly cleaned and then shredded to prevent any sensitive data being made available to external sources.

We visit websites on a daily basis, but how do we know how safe they are? No matter how genuine they look there’s every risk they’re a malicious website.

It’s estimated that up to 18.5 million websites are infected with malicious content. That’s around 1% of the total number of websites online. It may not sound a huge percentage, but it’s a percentage that could cause your business significant trouble.  And it’s a problem that most organizations aren’t entirely clear on. Malicious emails, for example, are well known due to the scare stories that flood our newsfeeds. But we’re less informed about malicious websites. And that’s what makes them dangerous.

However, if you’re able to understand the basics of a malicious website then you’re going to be in a much better position to avoid falling victim. So, what are malicious websites?

What is a Malicious Website?

A malicious website is like any other website on the internet: you connect to it with a browser. But if you dig a little deeper you’ll soon realize why it’s unlikely to become one of your favorite websites. The main objective of a malicious website is to install malware on to your PC. And, in most cases, it won’t even ask permission. The moment that you land on a malicious website is the moment that the malware starts downloading.

But why is a malicious website so misleading? Well, hackers are incredibly clever and they’re even more deceptive. That’s why they design malicious websites to look as genuine as possible. We, as humans, make quick decisions based on first impressions and, in this busy digital age, this is never truer than when online. Malicious websites take full advantage of this. And the false layer of trust that this engenders can soon lead to us clicking on links that we really shouldn’t.

How Do You Protect Yourself from Malicious Websites?

No one wants to fall victim to a malicious website. But, without a prior knowledge of how to protect yourself, this is difficult. Thankfully we’re here to make things easier. That’s why we’ve put together this amazing set of safety tips:

  • Always keep your software updated and install the latest patches as soon as possible. Malicious websites are often used to distribute malware that targets software vulnerabilities. With this updated protection in place you can minimize one of the main threats of malicious websites.
  • It’s vital that you never install any software you’re unfamiliar with. Malicious websites are sometimes courteous enough to ask permission before installing their malicious content. And it’s easy to click the Yes button just to clear the screen of yet another pop-up window. But it can spell disaster for your PC. Therefore, always read pop-up windows carefully and, if you don’t trust it, leave that website immediately.
  • If you’re sent a link to a website that’s unfamiliar then you shouldn’t click it. But you should do some research first. The best way to verify a mystery link is to type that link into the search box of a search engine. The results should soon highlight whether that web address is trustworthy or dangerous.
  • Install internet security software that can identify malicious websites before they’re loaded up. Knowledge of malicious websites can spread quickly and this has led to massive databases being created to help alert users to those that contain a threat.

Ransomware has been causing trouble for businesses for many years, so it’s clearly a form of hacking which needs greater understanding to avoid its wrath.

The name ransomware sounds a little threatening and, as with all hacks, it’s hardly the friendliest of exchanges. However, whilst most forms of malware – which ransomware is a strain of – tend to disrupt day to day operations of your IT equipment by either stealing data or putting a strain on your network through DDoS attacks, ransomware is different. Not only does it disrupt your IT operations, but it also delivers a financial threat to your organization.

Due to the double whammy contained within ransomware, it’s crucial that you understand the basics of ransomware, so let’s take a quick look.

What is Ransomware?

Believe it or not, but the very first recorded ransomware attack dates back to 1989 when a hacker was able to hide the files of an infected PC on its hard drive and encrypt the file names. And, to be honest, modern day ransomware still operates in a similar, if not more sophisticated, manner.

Ransomware is a form of malware which, when executed on a user’s PC, is able to take over the victim’s system and encrypt their files. Naturally, files are essential for any organization to operate efficiently and to their maximum productivity, so this is clearly a very debilitating attack. However, to add insult to injury, the hackers then demand a ransom fee to release a key which can decrypt the files and return them to a usable state.

How is Ransomware Executed?

The most common method employed by hackers to execute ransomware on a user’s PC is through phishing emails. These emails, which appear to be genuine, are highly deceptive methods of communication which convince the recipients that they need to open an attachment bundled with the email. However, these attachments are far from genuine and the most likely result of clicking them is that malicious software such as ransomware will be executed.

How Can You Combat Ransomware?

With the average ransom fee demanded by ransomware totaling around $12,000, it’s clearly an irritation that your organization can do without. Thankfully, there are a number of actions you can take to protect your business:

  • Regularly Backup Your Data: As long as your data is regularly backed up, there should be no need to pay the ransom fee. With a comprehensive backup route in place you will be able to easily retrieve your files from an earlier restore point when they weren’t encrypted. 
  • Work with Anti-Malware Software: Most ransomware can be detected by anti-malware software, so it stands to reason that installing this software should make a significant difference to your defenses. Updating this software as soon as any patches or upgrades become available, of course, should be made a priority as it could make a real difference to falling victim to newly released ransomware.

At the center of all unauthorized access to your computers or servers is a PC exploit. What are these exploits, though, and how do you protect against them?

Without the presence of an exploit, hackers find themselves in a position where gaining access to a victim’s PC is incredibly difficult. However, it suddenly becomes a lot easier if there’s an exploit available that they can take advantage of. It’s probably becoming clear, very quickly, that it’s crucial that you, as a PC user, also know about the existence of these exploits. Unfortunately, the level of knowledge that the average organization has regarding the nature of exploits is disturbingly low. And that’s why so many businesses fall victim to PC exploits.

If, however, your organization can begin to understand even the basics of PC exploits, then you stand to make your IT operations considerably more secure.

What is an Exploit?

The simplest way of looking at an exploit is by describing it as a hole in a security gate. Once hackers become aware of this hole then they can easily bypass your security by climbing through the hole impeded. If we’re talking slightly more technically, then this hole isn’t necessarily a hole but some form of weakness in your PC. These weaknesses can be found in operating systems, software code and any applications installed on your network. And the impact that exploits can have on these components can be devastating.

What Does an Exploit Do?

An exploit can work in a number of different ways; most commonly, a PC exploit is used to infect huge numbers of PCs. It only takes one PC to be infected to help kick-start a process whereby this infection spreads across networks within an organization and, eventually, across the world. This allows hackers to execute the following tasks:

  • Malicious software can be downloaded to PCs without the user’s knowledge
  • Vast amounts of sensitive data can easily be recorded and transmitted to remote locations
  • Ransomware can be used to encrypt data and extort payment in return for the un-encrypted data

How Do You Protect Yourself Against Exploits?

Exploits, of course, are the result of vulnerabilities that are already present on your PCs. Therefore, exploits are down to failures by developers and manufacturers in the design and testing phases of their products. As a result, once an exploit has been identified, any decent developer should work on remedying this exploit by producing a security patch. This patch can be installed on any vulnerable PC to effectively seal the hole in your security gate and keep any hackers out.

Final Thoughts

Exploits can cause major disruption to your organization very quickly due to the ease of access that they gift to hackers. Protecting your organization from these exploits, therefore, is vital to keep your PCs online and productive. Time and knowledge are important commodities when it comes to protecting against exploits, so make sure you remain up to date with not just the latest software patches, but also any breaking news on emerging exploits.

What are Zero-Day Vulnerabilities?

Zero-day vulnerabilities are frequently referenced in regards to PC security, but it’s also a term which most PC users will be completely unaware of.

Any vulnerability that is present in your organization’s IT network poses a significant danger to the security of your data and equipment. Educating yourself and your staff on the dangers posed by these vulnerabilities is an important security practice, so understanding what zero-day vulnerabilities are is a crucial step in securing your PCs.

To help you get started, we’ve put together a quick guide to provide you with a zero day introduction.

What Happens on Zero-Day?

The definition of a zero-day vulnerability is very simple; it’s any exploit or security bug that is present in software or hardware that isn’t patched as the software vendor isn’t aware of its existence. To be considered a true zero-day vulnerability it must also be known to hackers. And this is where it becomes a huge security concern.

With hackers aware of such an exploit (known as a zero-day exploit), they’re essentially granted free rein to continually exploit this vulnerability in the face of little opposition. Therefore, malware can be installed, data can be stolen and whole networks taken down without software vendors and customers being aware of how it’s happening.

Once the zero-day vulnerability has been confirmed and the software vendor made aware, Day Zero is established. Naturally, any period before Day Zero is highly problematic, but even the commencement of Day Zero provides little comfort. And this is because developing fixes and patches isn’t an instant process. Instead, time and effort needs to be invested in creating these patches and ensuring that customers install them as soon as possible.

What are Some Examples of Zero-Day Vulnerabilities?

Now that you understand a little more about the makeup of zero-day vulnerabilities, it’s time to consolidate that knowledge with some real life examples:

  • Microsoft Windows Vulnerability: Even the seasoned professionals at Microsoft are capable of falling foul to zero-day vulnerabilities with one recently being discovered in the system file Win32k.sys. The exploit can be launched by a specific malware installer and, without the relevant patch, can be considered very dangerous.
  • Adobe Flash Malware: Adobe have suffered numerous zero-day attacks and, in 2016, their users experienced a zero-day vulnerability packaged within an Office document. Activating this vulnerability allowed hackers to download malware to the affected PCs and begin exploiting data until Adobe hastily issued a patch.
  • Internet Explorer Loses Control: Microsoft was, again, victim of a zero-day vulnerability in December 2018 when their Internet Explorer app experienced a severe security risk. It’s believed that the vulnerability is exploited by directing victims to an infected website where the hackers can then assume control of the PC from a remote location.

Final Thoughts

Zero-day vulnerabilities are troubling security flaws as their very definition means that there is no immediate protection available. Accordingly, it’s important that your organization takes the following steps:

  • Always install all updates to ensure zero-day vulnerabilities are treated as soon as possible
  • Backup all data and store it correctly in the case of a zero-day vulnerability disrupting your network and productivity
  • Educate your staff on the dangers of zero-day vulnerabilities and ensure they’re aware of the telltale signs of infection
