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.

Cyber-crime remains a major threat to any organization that works with IT, but the basics of IT security are often the best way to counter this threat.

It’s difficult to avoid the fact that cyber-attacks are reaching record levels. IT systems are less secure than ever and need protecting. And that’s where your organization needs to take up the baton. Protecting these systems may sound like a monumental task, but it’s a lot easier than you think. Key to success is following the basics of IT security. The simplicity behind these processes is remarkable and can make a significant difference.

It’s crucial that you know what these are, so let’s take a look at the very basics of good IT security. 

Understanding the Basics

The complexity of IT systems often means they’re difficult to work with. And from this complexity comes flaws in security. The good thing is that IT security doesn’t have to be difficult. The best way you can help protect your IT system is by following these basics:

  • IT Inductions: You should never assume that new employees have a solid understanding of IT security. And that’s why your staff should always have to complete an IT induction. Not only will this familiarize them with the technology you use, but it allows you to run through the basics of cyber threats. This knowledge can make a real difference in strengthening your defenses. 
  • Disable USB Ports: The level of damage that USB devices can cause is shocking and unbelievable. Your employees are unlikely to be aware of this threat. To them, a USB port is simply a handy device for charging their mobile device. The truth is much different. This threat can be extinguished by disabling the USB ports. This can be achieved by adjusting the USB settings for your employees. 
  • Use Antivirus Software: It may feel like a simplistic step in IT security but antivirus software remains essential. Good antivirus software can recognize malware within milliseconds and flag it. A manual scan will never be able to match this. And your employees wouldn’t know what they were looking for. The vast databases in use and the speed in which they operate ensures that antivirus software is a must have in business. 
  • Assign Privileges Accordingly: Different employees will need different network privileges. These variations arise from the different tasks they perform within your IT system. Certain departments, for example, will need access to one drive whilst another department will not. Understanding these differences is critical. Once the necessary privileges have been identified then you can minimize the risk of cyber-attacks spreading through the entire system.

The Basics of Protecting Your Network

Computer networks are complex pieces of technology, but, thankfully, when it comes to protecting them, the processes are relatively simple.

If you’re an organization that works with PCs then the chances are that the backbone of your IT infrastructure will be a network. Packed full of benefits that enhance accessibility, speed and communication, a PC network is crucial for productivity. However, due to the incredible amount of data being transmitted across a network, these bastions of connectivity are squarely in the targets of hackers. And that’s why it’s important that your network is protected from any external threats.

You can, of course, invest heavily in a wide range of security solutions to protect your network, but it’s vital that you make sure you follow the basics as your best defense. So, if you want to know what these are, just take a look at our guide on the basics of protecting your network.

Always Use a Firewall

Your organization’s network is private and, therefore, the last thing you want is for third parties to be accessing the network and viewing its traffic. The most popular and effective method for preventing this is by installing a firewall. A piece of software that analyses incoming and outgoing activity, a firewall is a multi-layered form of defense that can monitor network activity, report unusual behavior and enforce security policies.

Work with Two-Factor Authentication

It’s highly likely that you’re familiar with the process of using login credentials to access networks and applications, but have you ever used two –factor authentication? While the standard practice of entering a login name and a password is highly secure, two-factor authentication makes it doubly so. The concept of two-factor authentication is that users have to go through two forms of authentication to gain access to the network e.g. after entering a username and password, users must then activate a link emailed to a secure email account.

Install Anti-Malware Software

Malware is any form of malicious software that aims to exploit vulnerabilities in your PCs (and their users) to gain access to your network. Naturally, this is the last thing you want, but it’s almost impossible to manually identify every threat entering your network. Therefore, it’s essential that you install anti-malware software to help protect your network. Capable of identifying the vast majority of active threats (and regularly updated against new ones), anti-malware software provides you with peace of mind that your defenses are strong.

Segment Your Networks

A simple way to enhance the security of your network is by segmenting it into individual sub-networks. Not only does this approach enhance the performance of each ‘segment’, it also increases the security of the network as a whole. For example, if a hacker manages to gain access to one of the segments, they will only have access to that one segment. The other sub-networks will be fenced off with their own unique security measures and, therefore, make it much harder for a hacker to gain access to the entire network.
