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

It’s important for small businesses to make the most of their IT capabilities, so understanding what the best IT practices are is paramount.

If you can implement the right IT practices in your organization then you’re clearly a smart thinker as it can only lead to increased productivity. However, for a small business this isn’t always the easiest strategy to formulate. The cost of investment can often restrict your use of brand new technology, so you need to be a little bit smarter. And the good news is that costs can be kept to a minimum.

To help you get started on getting the best out of your IT, I’ve put together a list of five best IT practices for small businesses.

  1. Backing up the Right Data

Backing up data can be an expensive process. Not only is physical storage costly, but cloud storage can soon start totting the dollars up. However, this is all dependent on the amount of data you want to back up. Therefore, if you can reduce the amount of storage you need to backup, you can reduce your storage costs. The best way to achieve this objective is by thoroughly researching how your data is used and determining exactly what you need to backup.

  1. Staff Security Knowledge

Cyber security should be a major concern for all businesses, but for a small business it’s crucial. With a wide range of new cyber-attacks such as ransomware and phishing emerging every day, the risk of your business operations being disrupted is high. Whilst firewalls and carefully secured, partitioned servers can make a huge difference, it’s even more useful for your employees to understand good security practices. All it takes is one malicious email to be clicked on to bring your organization to a halt, so ensure that regular refresher courses on security threats are conducted for your employees.

  1. Install all Updates

Keeping on the security theme, it’s essential that all updates for your software and hardware are installed as soon as possible. Once your IT equipment becomes even slightly out of date then it’s at risk of becoming vulnerable to hackers. However, if all the latest updates and firmware upgrades are installed, then you’re improving the defenses of your data no end.

  1. Good Power Protection

Your PC technology is important, so you need to ensure that it’s protected from the damaging effects of power outages and surges. Not only can these events reduce the lifespan of your technology, but they’re also capable of wiping data if they happen in the middle of a backup. To counter this risk, it’s vital that backup hardware comes with adequate battery support to keep backups running. Likewise, ensuring that your servers have reserve power supplies which are uninterruptible can help keep your data accessible and safe at all times.

  1. Provide Good Technical Support

Your business needs professional IT support, there simply isn’t any other option if you’re working with PCs. And when I say professional, I mean professionally trained and not a hobbyist who likes to tinker with their PC every now and then. Knowledge, after all, equals authority and when you’re working with complicated technology, you need as much authority as possible. Maybe this will be outsourced or maybe you’ll build an in-house team, either way it should be a priority for your organization.

5 Best Ways to Secure Your Backups

Data backups are crucial when it comes to protecting your data; it’s even more important to ensure that your backups are kept secure and available.

For many people, having data backed up is enough. However, what they fail to understand is that a backup is not infallible. In fact, there are a whole range of issues that could affect the stability of a backup. And, if your organization is in the midst of a data disaster, the one factor above all else that you should be concentrating on is security. Your backup, after all, is your lifeline to resuming productivity, so it should be as secure as possible.

To get you started, we’re going to look at the five best ways to secure your backups:

  1. Password Protect Your Backups

At the very least, you have to make sure that your backups are password protected. While, yes, it’s possible for a password to be cracked, it still acts as a deterrent and guarantees some level of security. The stronger the password, of course, the more protection you provide to your backup, so make sure that it’s unique and contains a mixture of uppercase, lowercase characters and numbers.

  1. Restrict Backup Access Rights

The more people that have access to your backups, the more risk there is that they could be compromised or damaged. Therefore, you should only ever assign access rights to the backup software to those members of staff who genuinely need it. Nominating those with access in advance will help to not only protect your backups, but also ensure that restores are completed quickly if the need arises.

  1. Integrate Encryption

There’s every chance that your entire backup could be snatched in the case of a data disaster, so it’s vital that it’s protected. After all, your backup is likely to contain data pertaining to your customers/staff and this could be highly sensitive. However, by encrypting the data contained within your backup, you’re rendering it next to useless in the hands of external parties.  Along with password protection, it’s a simple yet highly effective layer of defense.

  1. Store Physical Backups in a Safe

Although we live in an age where cloud backups are grabbing all the headlines, it’s still important that physical backups are also maintained. These can include: DVDs, optical disks and data tapes. Naturally, due to the data contained on them, these storage methods represent a high security risk and can’t just be stored on a shelf. The best solution is to invest in a safe, but make sure it’s fireproof as high levels of heat can easily distort and damage physical storage devices.

  1. Log all Backups

Most backup software will log details of the backups carried out, but when it comes to working with physical backups it’s a little different. As your physical backups will be stored somewhere, there needs to be a logging process of what is going where. It’s very easy for a single DVD to go missing, but, with a logging system in place, you should discover this sooner rather than later.

Backing up data is crucial for any organization, but it’s even more important that a good backup is performed or it may not be worth backing up at all.

Wasting time and resources on the wrong type of data or failing to backup data effectively can spell disaster for your restore options, so it’s essential you maximize the efficiency of your backup process. Understanding how you can improve and enhance your backup process, though, is a major struggle that many organizations face.

Therefore, we’ve put together a few pointers on how you can begin to reorganize your backup process and ensure that the data you need is available when you need it.

Keep Three Copies of Your Backup

The more sure-fire way to protect the availability of your data is by making multiple copies. The minimum you need is three, but what’s most important are the locations these backups are stored in. Naturally, you will want one copy based on site, but to minimize a loss of data you will also want two copies that are based off site. By storing these in, for example, a cloud based server or a remote data center, your organization can rest assured that a successful restore is almost guaranteed in almost all data loss scenarios.

Monitor Your Backups

As data gets bigger and bigger, the complexities behind backups increase accordingly. And this is why monitoring and analyzing your backups is more important than ever. To better understand how your system is coping then you will need to implement systems which can automatically survey servers and monitor how effective your backup process is and list any failures. Performing this kind of analysis manually is incredibly labor intensive and involves a lot of spreadsheets, so investing in specialized, automated software is vital to safeguard future backups.

Cloud Backup is Crucial

Cloud servers provide a highly elastic option for all your backup and restore needs, so there’s no excuse for not integrating them into your backup process. Not only can cloud servers help to counter the rapid increase in data size, but, as a remote system, they deliver fantastic protection from ransomware and other data disasters. Data can be transferred/accessed from cloud servers exceptionally quickly compared to traditional wide-area networks, so a cloud server can get your organization back on track quicker than ever before.

Protect Everything

While Windows is the primary target of most data attacks, it’s impossible to say that other services – such as the virtual application host Citrix – will not become the focus of attacks in the near future. Protecting all your servers and applications, therefore, allows you to keep your defenses fully manned and minimizes the amount of data loss that could occur. It’s important, however, that you don’t complicate your backup process with numerous pieces of software to help backup individual components. Instead, look for an all-in-one solution that can automate all the various backups and keep all your data safe.
