Some people would have you believe that as time has gone on, the need for rigorous business security has gone down. This is wrong! While it’s true that certain threats have been completely eliminated, crime is always a constant, and every generation sees a range of totally new corporate security risks.

Unfortunately, there’s nothing you can really do to stop criminals targeting your assets. However, you can certainly reduce the risk of any serious damage by understanding these threats, and taking preventative measures.

Here, we’ll look at some of the biggest security threats facing modern businesses, and what you can do to make sure you’re protected.

Your disgruntled employees

The first security risk you need to be aware of is disgruntled employees. I thought I’d get the worst of it out of the way first. The possibility that your own workers could have it in for your business can be pretty hard to swallow, but it’s a very real threat which you have to be aware of.

When a rogue employee is part of your IT department, and has fairly unlimited access to your data centers, networks and important accounts, it can lead to some very serious damage. Look at any study into major cyber-attacks or thefts, and you’ll see that an alarming amount of them were inside jobs.

This can be hard to crack down on, but certainly not impossible. The first thing you need to do is identify all those privileged accounts which have the potential to cause a security breach. If you haven’t been paying enough attention to your employee turnover, then have a big spring clean.

Terminate all those privileged accounts that are connected to people who no longer work for the business. From there, you need to have a system in place for constantly monitoring and controlling the account privileges which could be exploited.

Careless and uninformed employees

Another big threat which you have to be aware of is employees who are simply careless or uninformed, rather than malicious. Someone at your business who manages to lose a mobile device can often be just as dangerous as a saboteur.

By the same token, staff who aren’t properly trained in good security practices can be a big threat. They may use weak passwords, open malicious emails, or click on links to suspicious websites. While cybersecurity should be the biggest concern for any business owner in 2016, it’s also very important to consider physical, “old-fashioned” security risks as well.

Careless employees in an industrial setting may leave keys or sensitive documents out in the open for criminals to stumble upon and exploit. In this situation, your best bet is introducing a key tracking system, or looking into some security guard services.

When it comes to more modern, digital threats, you need to be training your employees on best cyber security practices, and offer them constant support wherever they need it.

Schedule a few training sessions outlining the importance of managing passwords, and how to make it harder for hackers to attack your company computers.

Mobile devices for work related tasks

Another big risk you need to be aware of is mobile devices in general, particularly when you’re running a BYOD system at your company. Ever since businesses have started using bring-your-own-device systems, it’s made business tech so much easier to manage and afford for small business owners.

However, they’ve also introduced a whole host of new cyber security threats. When employees are using their own mobile devices to share important data and access company information, it seriously ups the risk of data theft.

If your organization has embraced BYOD, or will do in the near future, then you need to be wary of the increased risk it carries. The only real thing you can do to mitigate this risk is set out a clear BYOD policy, and make sure all your employees are sticking to it.

With a clear set of rules in place, your employees will be better educated on how they’re expected to use their devices, and it will be easier for you to monitor emails and files which are being downloaded to employee and company-owned devices.

Effective monitoring will make it easier to understand the risk of mobile data loss, and pin down exposures if devices are ever lost or stolen.

Tthird-party service providers

The final security risk you need to know about is third-party service providers. As time goes on, tech has become progressively more complex and specialized.

This means that more and more business owners are having to outsource various technological functions to third party service providers in order to maintain and support different systems.

One common example is restaurant franchises which need to outsource the management and maintenance of their POS systems to third-party service providers. While these third-party providers use remote access tools to connect to the company’s own network, they don’t always follow the best security practices.

One common blunder is these providers using a single default password to connect to all of their clients remotely. In this scenario, a hacker only needs to get a hold of one password to gain access to every client’s network.

Many of the most high-profile cyber-attacks of the past few years have been due to a service provider’s credentials being stolen. These contractors may not have any malicious intent, but a blasé attitude to cyber security can end up causing massive damage to your company.

The best way around this kind of threat is vigorous vetting before you choose to go with any third-party service provider. Make sure that any third party you consider is following best practices when it comes to remote access.

Multi factor authentication, unique credentials for every single user, and setting least-privilege permissions are all good signs. It’s frustrating to have a breach due to your own carelessness, but even worse when you’re left to deal with someone else’s mess!

Take this advice, and you’ll do a lot to reduce the chances of a security breach at your company. Just remember that as much as you try to protect it, some security breaches are inevitable. Be aware of all the risks your company is facing, and have a plan in place for every scenario.
